    Templated electrodeposition as a scalable and surfactant-free approach to the synthesis of Au nanoparticles with tunable aspect ratios2022In: Nanoscale Advances, E-ISSN 2516-0230, Vol. 4, no 11, p. 2452-2467Article in journal (Refereed)
    Abstract [en]

    A high-throughput method for the fabrication of ordered arrays of Au nanoparticles is presented. It is based on pulsed electrodeposition into porous anodic alumina templates. In contrast to many synthesis routes, it is cyanide-free, prior separation of the alumina template from the aluminium substrate is not required, and the use of contaminating surfactants/capping agents often found in colloidal synthesis is avoided. The aspect ratio of the nanoparticles can also be tuned by selecting an appropriate electrodeposition time. We show how to fabricate arrays of nanoparticles, both with branched bases and with hemispherical bases. Furthermore, we compare the different morphologies produced with electron microscopies and grazing-incidence synchrotron X-ray diffraction. We find the nanoparticles are polycrystalline in nature and are compressively strained perpendicular to the direction of growth, and expansively strained along the direction of growth. We discuss how this can produce dislocations and twinning defects that could be beneficial for catalysis.

    The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar, and APOGEE-2 Data2022In: Astrophysical Journal Supplement Series, ISSN 0067-0049, E-ISSN 1538-4365, Vol. 259, no 2, article id 35Article in journal (Refereed)
    Abstract [en]

    This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 survey that publicly releases infrared spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the subsurvey Time Domain Spectroscopic Survey data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey subsurvey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated value-added catalogs. This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper, Local Volume Mapper, and Black Hole Mapper surveys.

    Accurate determination of the enhancement factor X for the nuclear Schiff moment in (TlF)-Tl-205 molecule based on the four-component relativistic coupled-cluster theory2020In: Molecular Physics, ISSN 0026-8976, E-ISSN 1362-3028, Vol. 118, no 23, article id e1767814Article in journal (Refereed)
    Abstract [en]

    Studies of parity (P) and time-reversal (T) symmetry violations using molecules are important and attractive because they are complementary to the high-energy tests of physics beyond the Standard Model of elementary particles. The focus of our present work is to surpass the current accuracies of the quantity X, an enhancement factor for the nuclear Schiff moment (Q), and the nucleon electric dipole moments for the (TlF)-Tl-205 molecule. We obtain X = 6856 a.u. using a relativistic coupled-cluster singles and doubles and perturbative triples (CCSD(T)) approach. This new value of X improves the upper limits for Q and the proton EDM by about ten percent over the previous ones. [GRAPHICS] .

    Jämförelse mellan betong och klimatförbättrad betong: Livscykelanalys inkluderande byggskede A1-5 och driftsenergi B6 i flerbostadshus2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Concrete is a leading building material due to its durability, strength and carrying capacity etcetera. A weakness of concrete is it´s relatively large carbon dioxide emissions that are released during the production process. At this current time cement production accounts to 5% of the world's GHG emissions. Boverket has set a specific requirement that new buildings must be climate declared as a guide to more sustainable construction.

    This  study  aims  to  investigate  and  use  a  model-based  LCA-assessments  where climate- improved concrete is compared to a traditional concrete. This was done by examining a BIM- model.

    The  possibility  of  improving  the  environmental  impact  is  answered  by  producing carbon dioxide emissions equivalent for concrete in this property and comparing it with carbon dioxide emissions  equivalent  for  a  climate-improved  concrete  to  show  a potential  carbon  dioxide saving.

    A quantitative method is selected for this study using LCA. LCA-assessment is performed using several computer-based BIM programs to be able to produce simulations and calculations. A reference building that represents an ordinary apartment building in Sweden forms the basis of the assessment.

    LCA is based on only one environmental indicator which is carbon dioxide emissions. LCA assessment for the two types of concrete include the construction phase A1-A5 as well as the phase B6 operating energy according to Swedish standard SS-EN 15978: 2011. No account is taken of any differences in strength, fire class and sound class when exchanging materials. LCC limits to utility calculation.

    Results shows the total price increases by approximately SEK 49,000 if the ordinary concrete is replaced with a climate-improved concrete, and the carbon dioxide emissions is reduced by approximately 57,000 kgCO2e.

    Reduction in the climate-impact of concrete partly helps in the climate policy framework 2045 for a climate-neutral Sweden. Climate-improved  concrete  has  limits  within exposure  and  strength  classes.  Surroundingenvironment must therefore be considered.

    The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra2020In: Astrophysical Journal Supplement Series, ISSN 0067-0049, E-ISSN 1538-4365, Vol. 249, no 1, article id 3Article in journal (Refereed)
    Abstract [en]

    This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17).

    Intervention for a correct medication list and medication use in older adults: a non-randomised feasibility study among inpatients and residents during care transitions2024In: International Journal of Clinical Pharmacy, ISSN 2210-7703, E-ISSN 2210-7711Article in journal (Refereed)
    Abstract [en]

    Background Medication discrepancies in care transitions and medication non-adherence are problematic. Few interventions consider the entire process, from the hospital to the patient’s medication use at home.

    Aim In preparation for randomised controlled trials (RCTs), this study aimed (1) to investigate the feasibility of recruitment and retention of patients and data collection to reduce medication discrepancies at discharge and improve medication adherence and (2) to explore the outcomes of the interventions.

    Method Participants were recruited from a hospital and a residential area. Hospital patients participated in a pharmacist-led intervention to establish a correct medication list upon discharge and a follow-up interview two weeks post-discharge. All participants received a person-centred adherence intervention for three to six months. Discrepancies in the medication lists, the Beliefs about Medicines Questionnaire (BMQ-S), and the Medication Adherence Report Scale (MARS-5) were assessed.

    Results Of 87 asked to participate, 35 were included, and 12 completed the study. Identifying discrepancies, discussing discrepancies with physicians, and performing follow-up interviews were possible. Conducting the adherence intervention was also possible using individual health plans for medication use. Among the seven hospital patients, 24 discrepancies were found. Discharging physicians agreed that all discrepancies were errors, but only ten were corrected in the discharge information. Ten participants decreased their total BMQ-S concern scores, and seven increased their total MARS-5 scores.

    Conclusion Based on this study, conducting the two RCTs separately may increase the inclusion rate. Data collection was feasible. Both interventions were feasible in many aspects but need to be optimised in upcoming RCTs.

    Surface optical reflectance combined with x-ray techniques during gas-surface interactions2020In: Journal of Physics D: Applied Physics, ISSN 0022-3727, E-ISSN 1361-6463, Vol. 53, no 22, article id 224001Article in journal (Refereed)
    Abstract [en]

    High energy surface x-ray diffraction (HESXRD), x-ray reflectivity (XRR), mass spectrometry (MS) and surface optical reflectance (SOR) have been combined to simultaneously obtain sub-second information on the surface structure and morphology from a Pd(100) model catalyst during in situ oxidation at elevated temperatures and pressures resulting in Pd bulk oxide formation. The results show a strong correlation between the HESXRD and SOR signal intensities during the experiment, enabling phase determination and a time-resolved thickness estimation of the oxide by HESXRD, complemented by XRR measurements. The experiments show a remarkable sensitivity of the SOR to changes in the surface phase and morphology, in particular to the initial stages of oxidation/reduction. The data imply that SOR can detect the formation of an ultrathin PdO surface oxide layer of only 2-3 angstrom thickness.

    Oxidation and Reduction of Ir(100) Studied by High-Energy Surface X-ray Diffraction2022In: The Journal of Physical Chemistry C, ISSN 1932-7447, E-ISSN 1932-7455, Vol. 126, no 11, p. 5244-5255Article in journal (Refereed)
    Abstract [en]

    The oxidation and reduction of an Ir(100) surface using 2.5, 5, and 10 mbar O2 partial pressure and a sample temperature of 775 K have been studied by using high-energy surface X-ray diffraction (HESXRD) which allowed to record large volumes of reciprocal space in short time periods. The complex 3D diffraction patterns could be disentangled in a stepwise procedure. For the 2.5mbar experiment the measurements indicate the formation of an Ir(100)-O c(2 × 2) oxygen superstructure along with the onset of epitaxial IrO2(110) bulk oxide formation. For the 5 and 10 mbar O2 partial pressures the formation of additional IrO2 bulk oxide epitaxies with (100) and (101) orientations as well as of polycrystalline IrO2 was observed. Upon CO reduction, we found the IrO2 islands to be reduced into epitaxial and metallic Ir(111) and (221) oriented islands.

    Theoretical investigation of α-iron chromium carbide (α-Fe/Cr7C3) interfaces2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). Six different α-Fe/Cr7C3 interfaceswere constructed α-Fe(001)/Cr7C3(024), α-Fe(001)/Cr7C3(202), α-Fe(001)/Cr7C3(040),α-Fe(110)/Cr7C3(024), α-Fe(110)/Cr7C3(202) and α-Fe(110)/Cr7C3(040). Due to limited computational resources, only one of them was computationally analyzed to determine its interfacial energy value. The results revealed that the interfacial energy of the α-Fe(001)/Cr7C3(040) interface falls within the range of incoherent interfaces, indicating its stability. The computed interfacial energy values ranged from 0.94 to 3.39 J/m2, consistent with similar studies on other iron interfaces. The simulations also identified minimum and local minimum points in the interface energy curve, representing stable configurations at specific interface separation distances. The presence of a minimum point at an interface separation value of d = 1.3551 Å with an interfacial energy of 0.94 J/m2 indicates the most stable configuration, while a local minimum point at d = 2.27 Å with an interfacial energy of 2.12 J/m2 suggests another stable configuration for the interface. The conclusion that the computations were correctly performed with an interfacial energy value of 0.94 J/m2 for the most stable configuration at a supercell length (aSupercell ) of 22.23 Å is drawn. The findings of this research have significant implications for future investigations and applications. Firstly, this study fills the gap of the unresearched ferrite-carbide interfaces with theoretical data. Secondly, the knowledge gained from studying these interfaces contributes to understanding hydrogen interactions, which is fundamental for the transition towards a hydrogen economy. Additionally, the incoherent nature of the interface introduces challenges in understanding material behavior and properties, necessitating further investigations for designing efficient systems. Future work includes experimental validation of the α-Fe/Cr7C3 interface to compare the theoretical and experimental energies and stability. Investigating the remaining interfaces and examining the effects of introducing hydrogen atoms in these interfaces, along with calculating the corresponding hydrogen trapping energies, are important research areas. Further advancements in understanding these interfaces can be achieved through interface engineering, multiscale modeling, and studying other iron-carbide systems.

    Abstract [en]

    Today's blue-collar workers have more tools and implements at their disposal than ever before. To perform their work, craftsmen are dependent on their tools and materials and must therefore always have easy access to them. Trousers-pouches for craftsmen are available in various types as a complement to pockets. A interchangeable variant is produced by Cirk-L but these lack a storage solution for smooth transport of several pouches. Their trouser-pouches are intended to be changed when different tools and materials are needed. The problem is that there is no system that manages the trouser-pouches and contents when they are not in use. The purpose of the study is to develop a solution that makes it possible to transport Cirk-L's pouches smoothly. The goal is to develop a prototype of a storage solution through a concept development process, material selection, CAD modeling with detailed drawings and finite element analysis for strength calculations. Calculations are performed using the MATLAB extension CALFEM and are simulated in Creo for dimensioning. Material selection for all components is performed with regard to sustainability from an environmental perspective. The process results in a prototype that meets the desired requirements. The storage solution can carry six trousers on the outside and various tools on the inside.

    Addressing and transforming complexities in cities: Exploring logics and routines in Sweden2024In: / [ed] Peter Palm; Sylwia Lindqvist, 2024Conference paper (Other academic)
    Abstract [en]

    Well-managed urbanization can be a transformative force towards socially and environmentally sustainable cities. The transformative change relies on knowledge and collaborative action, rather than disconnected knowledges from different scientific disciplines and of sectorial actors. A problem that hinders collaborative action is the complexity of sustainable urbanization. In this paper we aim to expand thinking on urban transformation from a multisectoral and tri-disciplinary research perspective. 

    Methods in use are tri-disciplinary essays to identify multisectoral interests, logics and routines in urban transformation. Essayistic insights form and develop three analytical dialogues on a range of urban transformation specificities in the urban complexity and related to sustainable urbanization. The essays are collaboratively interpreted as a Saskia Sassen inspired de-theorising process to get hold of complexities in cities by social, self-reflective and introspective processes. 

    There are multi-sectoral issues difficult to develop with current modes of thinking and independent logic of developments. A re-theorization is proposed with collective ways of understanding, interacting and developing urban sustainable solutions that aims to appropriately address the complexities of the urban environment. Two ways of thinking and acting is contrasted. Independent and interdependent logics of leadership cultures for sustainable development are considered as a new way to theorise around the sustainable city. 

    Implications concern complexities in cities such as how to design and develop urban projects that embraces actors' concerns and knowledge for sustainable development. There appear many simultaneous action nets of urban transformation specificities. These are based on actors’ logics, routines, ambitions, and collaboration. Leadership for transformation is not the independent cultures with one or few actors in the action nets but the interdependent culture making room for and adapt specificities of the engaged actors.

    Industrialization of construction: Implications on standards, business models and project orientation2020In: Organization Technology and Management in Construction, ISSN 1847-5450, Vol. 12, no 1, p. 2109-2116Article in journal (Refereed)
    Abstract [en]

    Digitalization has the potential to radically change the way buildings are designed, produced, and operated. In this digital transformation, the establishment of information standards play an important role. However, despite substantial efforts in the development of both technology and standards, these are not yet fully adopted in construction. This study aims to review the adoption of standards and to examine whether suppliers of prefabricated concrete elements have transformed their business models. The purpose is to strengthen the understanding of the interplay between the adoption of standards and business model renewal. Driving forces for the adoption of standards are identified and coupled with suppliers' arguments for business model protection and renewal, explained in terms of a market and a hierarchy approach. The market approach embraces the adoption of open standards for improved competition and information exchange along with the further adoption of industrialized construction. This study identifies that common standards for precast elements are lacking, which leads to waste in terms of structural re-design and liability uncertainties. On the other hand, a market situation with open standards is challenging for suppliers to utilize and benefit from their existing operational platforms. Suppliers of precast elements strive for a hierarchy approach, that is, the adoption of the whole value chain, to protect their market position and continue offering structural frameworks and services. This concurs with arguments for industrialized construction, which emphasize the benefits of continuous improvements. This study contributes to the understanding of drivers and impediments for the up-take of standards versus business model renewal in construction.

    Industrialized and project-based construction: standards versus business models2019In: Creative Constructive Conference - Proceedings, Budapest University of Technology and Economics , 2019, p. 362-367Conference paper (Refereed)
    Abstract [en]

    Digitalization transforms the design, construction and operation of buildings and brings promises of integrated information exchange, ease of communication and productivity improvements for the whole construction sector. These promises depend significantly on the establishment of common information standards, i.e. rules and classification of information. However, despite rigorous efforts on development of standards and considerable technology advancements, standards are not yet fully adopted in construction and benefits from digitalization are not fully capitalized. The objective of this study is to review the adoption of standards and business model renewal for industrialized suppliers of precast concrete elements, with the purpose of reaching enhanced understanding of the mechanisms of standards adoption and business model renewal. The study identifies driving forces for adoption of standards that counteract with arguments for business renewal, explained in terms of a market versus a hierarchy approach in this context. The market approach promotes adoption of open standards for enhanced competition, ease of communication and information exchange as well as improved utilization of industrialized construction. The existing lack of common standards for precast elements, identified in this study, render e.g. waste due to structural re-design and liability uncertainties. However, on a market with open standards, the precast suppliers find it difficult to fully utilize and benefit from their existing operational platforms. Precast supplier search for adoption of the whole value chain of precast structural frameworks, i.e. a hierarchy approach, to protect their market position and maintain their business offerings of complete structural frameworks that include design, manufacturing, logistical services as well as on-site assembly. The integrated hierarchy approach concurs with arguments for industrialized construction, i.e. collecting experiences from design, manufacturing, logistics and assembly as a basis for continuous improvements. The study thus contributes to the understanding of drivers and impediments for adoption of standards versus business renewal in construction.

    Product Service Systems in Construction Supply Chains2018In: Proceedings - Creative Construction Conference, Diamond Congress Ltd. , 2018, p. 635-640Conference paper (Refereed)
    Abstract [en]

    The shipbuilding, automotive and aerospace industries are examples of industries offering product service systems (PSS) to their customers, i.e. they combine physical products with services to add increased value. While product service systems are well established in many manufacturing industries, it has barley emerged in construction, which is mainly explained by the well-established project-based organisation of construction work. Thus, implementation of product and service systems in construction will challenge the established utilisation of technical solutions and systems, production processes and supply chains. The objective of this study is to identify and critically review examples of product service systems in construction supply chains, with the purpose of describing how it challenges prevailing business systems and organisation of construction work. The study rests upon empirical data collected in two case studies at Gyproc Saint-Gobain in Denmark and Celsa Steel Service in Sweden. The two case studies reveal significant challenges related to the implementation and marketing processes of product service systems. Companies that develop and expand their business offers by providing new product service systems find themselves operating in two parallel market segments, i.e. the traditional market of construction components and the new market of product service systems. The product service systems reviewed in the two case studies show a strong focus and emphasis on the development of the offer and the operational platform, while the companies’ roles and market positions remain unchanged. Thus, the case study companies organise and operate their businesses and market relations as before the implementation of the product service system. The conclusion is that development and implementation of product service systems in construction supply chains, even at the low end of product complexity represented by single building components, require awareness in the companies’ offer of products and services, development in operational platforms as well as clear market position.

    Abstract [en]

    The shipbuilding, automotive and aerospace industries are examples of industries offering product service systems (PSS) to their customers, i.e. they combine physical products with services to add increased value. While product service systems are well established in many manufacturing industries, it has barely emerged in the fragmented and project-based organisation of construction. The objective of this study is to identify and critically review examples of product service systems in construction supply chains, with the purpose of describing how it challenges prevailing business systems and organisation of construction work. The study rests upon two case studies carried out at Gyproc Saint-Gobain in Denmark and Celsa Steel Service in Sweden. The findings reveal significant challenges related to the implementation and marketing of the product service systems provided. Companies that develop and expand their business offers by providing new product service systems tend to find themselves operating in two parallel market segments, i.e. the traditional market of construction components and the new market of product service systems. The PSS-offers reviewed in the case studies show a strong focus and emphasis on the development of the offer and the operational platform, while the companies’ market positions remain unchanged. Thus, the case study companies organise and operate their businesses and market relations as before the implementation of the product service system. The conclusion is that development and implementation of product service systems in construction supply chains requires awareness in the companies’ offer of products and services, well-established operational platforms, and particularly, a renewed market position.

    Theoretical hyperfine structures of F-19 I and O-17 I2018In: Physical Review A: covering atomic, molecular, and optical physics and quantum information, ISSN 2469-9926, E-ISSN 2469-9934, Vol. 97, no 3, article id 032506Article in journal (Refereed)
    Abstract [en]

    Multiconfiguration Hartree-Fock (MCHF) and multiconfiguration Dirac-Hartree-Fock (MCDHF) calculations are performed for the 2p(5) P-2 degrees, 2p(4)(P-3)3s P-4, 2p(4)(P-3)3s P-2, and 2p(4)(P-3)3 p S-4 degrees states of F-19 I to determine their hyperfine constants. Several computing strategies are considered to investigate electron correlation and relativistic effects. High-order correlation contributions are included in MCHF calculations based on single and double multireference expansions. The largest components of the single reference MCHF wave functions are selected to define the multireference (MR) sets. In this scheme, relativistic corrections are evaluated in the Breit-Pauli approximation. A similar strategy is used for the calculation of MCDHF relativistic wave functions and hyperfine parameters. While correlation and relativistic corrections are found to be rather small for the ground state, we highlight large relativistic effects on the hyperfine constant A(3/2) of 2p(4)(P-3)3 p(4)S(degrees) and, to a lesser extent, on A(1/2) of 2p(4)(P-3)3s P-4. As expected for such a light system, electron correlation effects dominate over relativity in the calculation of the hyperfine interaction of all other levels considered. We also revisit the hyperfine constants of 2p(3)((4)(S))3s S-5 degrees and 2p(3)(S-4)3 p P-5 in O-17 using similar strategies. The results are found to be in excellent agreement with experiment.

    A semi-analytical coupled simulation approach for induction heating2021In: Advanced Modeling and Simulation in Engineering Sciences, ISSN 2213-7467, Vol. 8, no 1, article id 14Article in journal (Refereed)
    Abstract [en]

    The numerical simulation of the induction heating process can be computationally expensive, especially if ferromagnetic materials are studied. There are several analytical models that describe the electromagnetic phenomena. However, these are very limited by the geometry of the coil and the workpiece. Thus, the usual method for computing more complex systems is to use the finite element method to solve the set of equations in the multiphysical system, but this easily becomes very time consuming. This paper deals with the problem of solving a coupled electromagnetic - thermal problem with higher computational efficiency. For this purpose, a semi-analytical modeling strategy is proposed, that is based on an initial finite element computation, followed by the use of analytical electromagnetic equations to solve the coupled electromagnetic-thermal problem. The usage of the simplified model is restricted to simple geometrical features such as flat or curved surfaces with great curvature to skin depth ratio. Numerical and experimental validation of the model show an average error between 0.9% and 4.1% in the prediction of the temperature evolution, reaching a greater accuracy than other analyzed commercial softwares. A 3D case of a double-row large size ball bearing is also presented, fully validating the proposed approach in terms of computational time and accuracy for complex industrial cases.

    Influence of induction hardening residual stresses on rolling contact fatigue lifetime2022In: International Journal of Fatigue, ISSN 0142-1123, E-ISSN 1879-3452, Vol. 159, article id 106781Article in journal (Refereed)
    Abstract [en]

    Rolling contact fatigue is a unique mode of fatigue that components under cyclic contact loading experience. In this work, the impact of induction hardening residual stresses in rolling contact fatigue lifetime is investigated experimentally and numerically using the Dang Van multiaxial criterion. Various residual stress fields from induction hardening are simulated using the finite element method and are mapped into a classical monocontact finite element model. The impact of induction hardened residual stresses on the lifetime of a component has been investigated, and the importance of incorporating the residual stress profile into fatigue life assessments is affirmed.

    Numerical and experimental investigation of residual stresses during the induction hardening of 42CrMo4 steel2022In: European journal of mechanics. A, Solids, ISSN 0997-7538, E-ISSN 1873-7285, Vol. 96, article id 104766Article in journal (Refereed)
    Abstract [en]

    The usage of induction hardening in the industry has increased in the last years due to its efficiency and repeatability. Induction hardening produces a hard martensitic layer on the specimen surface, which is accompanied by the generation of compressive residual stresses in the hardened case and tensile stresses in the untreated core. Residual stresses generated by induction hardening greatly impact on fatigue performance, as they act as crack growth retardants. In this work, a multiphysical coupled finite element model is developed to simulate induction hardening and compute the final residual stress state of the specimens along the microstructural transformations and hardness evolution. The impact of the transformation induced plasticity strain in the stress-state of the specimen during the process is also studied. The experimental validation shows that considering the transformation induced plasticity in induction hardening simulations improves the residual stress predictions, concluding that this effect should be included to achieve good residual stress predictions, especially in the subsurface region.

    Numerical and experimental investigation on the residual stresses generated by scanning induction hardening2022In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 108, p. 827-832Article in journal (Refereed)
    Abstract [en]

    Induction hardening is widely used in the industry as a surface heat treatment that improves the surface and the subsurface hardness of components greatly. The hardened case, which usually is a few mm, highly impacts the surface and structural integrity of the component. In this work, we simulate the scanning induction hardening process by means of finite element modeling. The computed hardness, microstructure, and residual stress profile are compared with experimentally measured data using several surface and subsurface characterization techniques. A very good agreement is found between the simulated and experimentally measured residual stresses, which were characterized by the incremental hole drilling technique.

    Predicting the induction hardened case in 42CrMo4 cylinders2020In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 87, p. 545-550Article in journal (Refereed)
    Abstract [en]

    Induction hardening has the potential to produce favorable surface integrity that can improve fatigue performance and extend the lifetime of a component. The localized superficial heating provided by induction is the main advantage of this process, as it allows the core to remain intact and, therefore, ductile, while the surface is hardened. Achieving favorable characteristics in the hardened case is of great importance, as this process is usually applied to load bearing and wear-susceptible metallic components. The simulation of the hardening process by induction heating is a complex and challenging task at which many efforts have been directed in the last years. Due to the numerous interactions of the many physics that take part in the process (electromagnetic, thermal, microstructural and mechanical), a highly coupled finite element model is required for its numerical simulation. In this work, a semi-analytical induction heating model is used to compute the induction hardening process, predicting the size and shape of the hardened layer and the distribution of the hardness. Using the semi-analytical model allows the computational time to be much faster compared to a fully coupled model using a commercial software, where the time consumption for the presented 2D case is reduced by 20 %. Experimental validation is presented for cylindrical 42CrMo4 billets heated by a short solenoidal inductor, which shows good agreement with the predicted results, reaching an average error of 3.2 % in temperature estimations.

    Controlling the adhesive pull-off force via the change of contact geometry2021In: Philosophical Transactions. Series A: Mathematical, physical, and engineering science, ISSN 1364-503X, E-ISSN 1471-2962, Vol. 379, no 2203, article id 20200392Article in journal (Refereed)
    Abstract [en]

    A first-order asymptotic analysis of the Griffith energy balance in the Johnson-Kendall-Roberts model of adhesive contact under non-symmetric perturbation of the contact geometry is presented. The pull-off force is evaluated in explicit form. A particular case of adhesive contact between a relatively stiff sphere and an elastic half-space is considered under the assumption that the sphere geometry is changed by the application of an arbitrary lateral normal surface loading. The effect of the sphere Poisson's ratio on controlling the adhesive pull-off force is considered.

    From Winkler's Foundation to Popov's Foundation2019In: Facta Universitatis-Series Mechanical Engineering, ISSN 0354-2025, Vol. 17, no 2, p. 181-190Article in journal (Refereed)
    Abstract [en]

    In recent years, the method of dimensionality reduction (DR) has started to figure as a very convenient tool for dealing with a wide class of elastic contact problems. The MDR modeling framework introduces an equivalent punch profile and a one-dimensional Winkler-type elastic foundation, called henceforth Popov's foundation. While the former mainly accounts for the geometry of contact configuration, the Popov foundation inherits the main characteristics of both the contact interface (like friction and adhesion) and the contacting elastic bodies (e.g., anisotropy, viscoelasticity or inhomogeneity). The discussion is illustrated with an example of the Kendall-type adhesive contact for an isotropic elastic half-space.

    On the Size Effects in Indentation Testing of Elastic Functionally-graded Materials2019In: New Achievements in Continuum Mechanics and Thermodynamics: A Tribute to Wolfgang H. Müller / [ed] Bilen Emek Abali, Holm Altenbach, Francesco dell'Isola, Victor A. Eremeyev, Andreas Öchsner, Springer, 2019, p. 17-28Chapter in book (Refereed)
    Abstract [en]

    The size effect in the small-scale indentation testing is studied for a functionally-graded material (FGM) whose shear elastic modulus varies according to the exponential law. Under the simplifying assumption of zero Poisson’s ratio, the asymptotic model of the indentation stiffness for an axisymmetric frictionless indenter is developed in the case when the contact radius is small compared to the inhomogeneity characteristic size. The so-called sample size effect is considered on the example of a simply supported FGM plate indented at the center of its top surface. A certain range of applicability of the first-order asymptotic models has been established by comparison with the approximate analytical solution available in the literature.

    A vanishing at infinity solution of the three-dimensional Laplace equation is sought in an a priori unknown domain with overdetermined boundary conditions, the right-hand sides of which depend on the unit normal to the free boundary. A perturbation analysis of the nonstandard free boundary problem that models deep abrasive drilling has been performed under the assumption that the free boundary is close to the surface of a given semi-infinite cylinder, the longitudinal position of which depends on the boundary data, and the leading-order asymptotic solution has been developed.

    Unilateral adhesive contact between a rigid indenter and a uniformly stretched membrane of arbitrary shape is considered. The generalized Johnson-Kendall-Roberts (JKR)-type and Derjaguin- Muller-Toporov (DMT)-type models of non-axisymmetric adhesive contact are presented for short- and long-range adhesion, respectively, and the JKR-DMT transition is established in the framework of the generalized Maugis-Dugdale model. A refined method of matched asymptotic expansions is applied to construct the leading-order asymptotic model for indentation mapping of freestanding two-dimensional materials with an axisymmetric probe, using the approximate analytical solution obtained in explicit form for an infinite membrane in the limit of short-range adhesive contact with an indenter in the form of an elliptic paraboloid. The cases of a spherical indenter and a rectangular membrane are studied in detail.

    Abstract [en]

    A contact problem of electroadhesion for a conductive elastic body pressed against a rigid plane surface of a dielectric coating covering a conductive substrate is formulated applying the Johnsen-Rahbek approximation for the attractive surface stresses and the Derjaguin-Muller-Toporov (DMT) hypothesis about the influence of the adhesive stresses on the deformable shape of the elastic body. An approximate solution is obtained using the Winkler-Fuss deformation model with the equivalent (contact load dependent) stiffness coefficient evaluated according to the Xydas-Kao soft finger model. The friction force under applied voltage is evaluated as the product of the coefficient of friction and the integral of the macro contact pressure over the apparent contact area. The upper and lower estimates for the friction force are discussed in the case of absence of any external normal load.

    A simple mathematical model for the resonance frequency analysis of dental implant stability: Implant clamping quotient.2019In: Mechanics research communications, ISSN 0093-6413, E-ISSN 1873-3972, Vol. 95, p. 67-70Article in journal (Refereed)
    Abstract [en]

    A simple mathematical model for free vibrations of an elastically clamped beam is suggested to interpret the results of the resonance frequency analysis developed for implant stability measurements in terms of the Implant Stability Quotient (ISQ) units. It is shown that the resonance frequency substantially depends on the lateral compliance of the implant/bone system. Based on the notion of the lateral stiffness of the implant/bone system, a new measure of the implant stability is introduced in the form similar to the ISQ scale and is called the Implant Clamping Quotient (ICQ), because it characterizes the jawbone’s clamp of the implant. By definition, the ICQ unit is equal to a percentage of the original scale for the lateral stiffness of the implant/bone system.

The effect of the body surface reinforcement is discussed. The case of a uniform (symmetric) settling is considered in detail.

    A note on artificial neural network modeling of vapor-liquid equilibrium in multicomponent mixtures2019In: Fluid Phase Equilibria, ISSN 0378-3812, E-ISSN 1879-0224, Vol. 502, article id 112282Article in journal (Refereed)
    Abstract [en]

    Application of artificial neural networks (ANNs) for modeling of vapor-liquid equilibrium in multicomponent mixtures is considered. Two novel ANN-based models are introduced, which can be seen as generalizations of the Wilson model and the NRTL model. A unique feature of the proposed approach is that an ANN approximation for the molar excess Gibbs energy generates approximations for the activity coefficients. A special case of the ternary acetic acid-n-propyl alcohol-water system (at 313.15 K) is used to illustrate the efficiency of the different models, including Wilson's model, Focke's model, and the introduced generalized degree-1 homogeneous neural network model. Also, the latter one-level NN model is compared to the Wilson model on 10 binary systems. The efficiency of the two-level NN model is assessed by a comparison with the NRTL model.

    Analysis of the minimal model for the enthalpy relaxation and recovery in glass transition: application to constant-rate differential scanning calorimetry2021In: Continuum Mechanics and Thermodynamics, ISSN 0935-1175, E-ISSN 1432-0959, Vol. 33, p. 107-123Article in journal (Refereed)
    Abstract [en]

    The so-called minimal model is formulated for describing the enthalpy relaxation and recovery in glass transition. The model is based on the Arrhenius law for the enthalpy relaxation, which uses two-dimensional parameters, namely the activation energy and the so-called pre-factor (relaxation time at relatively high temperature). A numerically effective exact analytical solution is obtained for the case of constant-rate differential scanning calorimetry. The developed model is analyzed according to the logic of the model itself without introducing additional simplifying assumptions of thermodynamic nature. For typical range of the model parameters, the resulting differential equation contains a large parameter, which offers an opportunity for the application of asymptotic and approximate techniques. A number of simple approximations have been provided for some thermodynamic quantities of interest.

    Axisymmetric JKR-type adhesive contact under equibiaxial stretching2021In: The journal of adhesion, ISSN 0021-8464, E-ISSN 1563-518X, Vol. 97, no 2, p. 140-154Article in journal (Refereed)
    Abstract [en]

    An axisymmetric frictionless adhesive contact problem for a spherical indenter pressed against an isotropic elastic incompressible half-space under equibiaxial stretching is studied in the framework of the generalized Johnson-Kendall-Roberts (JKR) theory, which accounts for the effect of weak coupling between fracture modes I and II by means of a phenomenological mode-mixity function. The model predicts that contact area can withstand a larger level of the substrate stretch under moderate pre-pulling force. We have provided simple formulas to evaluate the pull-off force and the critical contact radius at the detachment point.

    Elliptical adhesive contact under biaxial stretching2020In: Proceedings of the Royal Society. Mathematical, Physical and Engineering Sciences, ISSN 1364-5021, E-ISSN 1471-2946, Vol. 476, no 2233, article id 20190507Article in journal (Refereed)
    Abstract [en]

    Adhesive contact of the Hertzian indenter with an incompressible elastic substrate bi-directionally stretched along the indenter principal planes of curvature is considered in the Johnson-Kendall-Roberts theoretical framework. An approximate model is constructed by examining energy release rate conditions only on the edges of the minor and major axes of the contact ellipse. The effect of weak coupling between fracture modes I and II is introduced using a phenomenological mode-mixity function. This study was motivated by the need to model a passive-adhesive mechanism in cell mechanics on stretchable substrates.

    MCDHF and RCI calculations of energy levels, lifetimes, and transition rates in Si III and Si IV2019In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, ISSN 0004-6361, Vol. 631, article id A29Article in journal (Refereed)
    Abstract [en]

    We present extensive multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations including 106 states in doubly ionized silicon (Si III) and 45 states in triply ionized silicon (Si IV), which are important for astrophysical determination of plasma properties in different objects. These calculations represents an important extension and improvement of earlier calculations especially for Si III. The calculations are in good agreement with available experiments for excitation energies, transition properties, and lifetimes. Important deviations from the NIST-database for a selection of perturbed Rydberg series are discussed in detail.

    Extended relativistic multiconfiguration calculations of energy levels and transition properties in singly ionized tin2023In: Journal of Quantitative Spectroscopy and Radiative Transfer, ISSN 0022-4073, E-ISSN 1879-1352, Vol. 294, p. 108392-108392, article id 108392Article in journal (Refereed)
    Abstract [en]

    Multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) calculations are performed for 22 states in singly ionized tin (Sn II) belonging to the 5s2ns (n=6,7), 5s2nd (n=5,6), 5s5p2 even parity configurations and the 5s2np (n=5,6,7), 5s24f odd parity configurations. Valence-valence and core-valence correlation effects are taken into account through configuration state function (CSF) expansions. Complete and consistent data sets of level energies, wavelengths, oscillator strengths, lifetimes and transition rates among all these states are given. The results are compared with existing theoretical and experimental results. There is an excellent agreement for calculated excitation energies with experimental data from the NIST database. Lifetimes and transition rates are also in agreement with the results from previous calculations and available measurements for most of the transitions.

    Generalizations of p-Laplace operator for image enhancement: Part 22020In: Communications on Pure and Applied Analysis, ISSN 1534-0392, E-ISSN 1553-5258, Vol. 19, no 7, p. 3477-3500Article in journal (Refereed)
    Abstract [en]

    We have in a previous study introduced a novel elliptic operator Delta((p,q))u = vertical bar del u vertical bar(q) Delta(1)u + (p - 1) vertical bar del u vertical bar(p-2)Delta(infinity) u, p >= 1, q >= 0, as a generalization of the p-Laplace operator. In this paper, we establish the well-posedness of the parabolic equation u(t) =vertical bar del u vertical bar(1-q) Delta((1+q,q)), where q = q(vertical bar del u vertical bar) is continuous and has range in [0, 1], in the framework of viscosity solutions. We prove the consistency and convergence of the numerical scheme of finite differences of this parabolic equation. Numerical simulations shows the advantage of this operator applied to image enhancement.

    En analys av skillnaden på beräknad klimatpåverkan för en byggnad i olika beräkningsverktyg2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Sweden, the construction and real estate sector accounts for 21 percent of the totalgreenhouse gas emissions where imported goods are included. Construction of new buildingsaccounts for a third of the total emissions caused by the Construction and Real Estate sector.Sweden aims to achieve zero net emissions by 2045.The purpose of the study is to investigate how much the climate impact differs if the climatedata largely consists of specific data and generic data, respectively. The study examined thedifferences that arise when producing climate declarations in three different software.To achieve the purpose of the study and answer set questions, a literature study, interviewstudy and a quantitative survey were conducted. The quantitative study was based onproducing five different climate declarations for a fictitious building provided by OneClickLCA. Two of five climate declarations produced are largely based on specific data. Theclimate calculations were performed in OneClick LCA, Bidcon and the IVL constructionsector's environmental calculation tools. The mentioned software was best known amongselected respondents.

    The results from the calculations are presented below:

    ● Oneclick LCA specific climatdata1: 230 600 kg CO₂e

    ● Oneclick- LCA specific climatdata2: 179 300 kg CO₂e

    ● OneClick LCA generic climatdata: 269 000 kg CO₂e

    ● Bidcon generic climatdata: 273 000 kg CO₂e

    ● IVL Byggsektorns miljöberäkningsverktyg generic climatdata: 266 000 kg CO₂e

    The study showed that the difference in the total calculated climate impact is marginalbetween the different calculation programs that were examined. The study also showed thatclimate calculations that are mostly based on specific data result in a lower calculated climateimpact compared to generic data. Despite the selection of EPDs with a high climate impact,the result of the total calculated climate impact was 16 percent lower compared to genericdata.

    Abstract [en]

    Sales of three-wheeled motorcycles are expected to increase in the coming years. Demand is increasing, especially for electric tricycles. To succeed in the automotive industry, the vehicles that are developed need to be safe. Safety is a high priority in the development of Omotion AB’s vehicles. OMotion has two problems with its latest three-wheeled motorcycle Where the solutions can contribute to increased safety. The dashboard behind the steering wheel is obscured when the steering wheel is turned. The previous model of the steering system does not interact with the 3D model of the vehicle realistically. New concept with prototype of display is developed with a product development process. The product development process includes a concept development, development at system level, detailed development and testing. 3D model för a new control system that interacts correctly is developed with the CAD program SolidWorks. Simpler physical calculations are performed with knowledge in solid mechanics and machine elements.The results are solutions to OMotion’s two problems. A physical and analytical prototype for the steering wheel’s integrated display has been developed, as well as a realistic 3D model of the steering system. The steering system model enables control of the motorcycle model in SolidWorks

    Ab initio calculations of the hyperfine structure of zinc and evaluation of the nuclear quadrupole moment Q(Zn-67)2018In: Physical Review A: covering atomic, molecular, and optical physics and quantum information, ISSN 2469-9926, E-ISSN 2469-9934, Vol. 97, no 6Article in journal (Refereed)
    Abstract [en]

    The relativistic multiconfiguration Dirac-Hartree-Fock and the nonrelativistic multiconfiguration Hartree-Fock methods have been employed to calculate the magnetic dipole and electric quadrupole hyperfine structure constants of zinc. The calculated electric field gradients for the 4s4p P-3(1)degrees and 4s4p P-3(2)degrees states, together with experimental values of the electric quadrupole hyperfine structure constants, made it possible to extract a nuclear electric quadrupole moment Q((67) Zn) = 0.122(10) b. The error bar was evaluated in a quasistatistical approach-the calculations were carried out with 11 different methods, and then the error bar was estimated from the differences between the results obtained with those methods.

    Abstract [en]

    Context. The age, evolution, and chemical properties of the Galactic disk can be effectively ascertained using open clusters. Within the large program Stellar Populations Astrophysics at the Telescopio Nazionale Galileo, we specifically focused on stars in open clusters, to investigate various astrophysical topics, from the chemical content of very young systems to the abundance patterns of lesser studied intermediate-age and old open clusters.

    Aims. We investigate the astrophysically interesting element fluorine (F), which has an uncertain and intriguing cosmic origin. We also determine the abundance of cerium (Ce), as F abundance is expected to correlate with the s-process elements. We intend to determine the trend of F abundance across the Galactic disk as a function of metallicity and age. This will offer insights into Galactic chemical evolution models, potentially enhancing our comprehension of this element’s cosmic origin.

    Methods. High-resolution near-infrared spectra were obtained using the GIANO-B spectrograph. The Python version of Spectroscopy Made Easy (PySME), was used to derive atmospheric parameters and abundances. The stellar parameters were determined using OH, CN, and CO molecular lines along with Fe I lines. The F and Ce abundances were inferred using two K-band HF lines (λλ 2.28, 2.33 µm) and two atomic H-band lines (λλ 1.66, and 1.71 µm), respectively.

    Results. Of all the clusters in our sample, only King 11 had not been previously studied through medium- to high-resolution spectroscopy, and our stellar parameter and metallicity findings align well with those documented in the literature. We have successfully inferred F and Ce abundances in all seven open clusters and probed the radial and age distributions of abundance ratios. This paper presents the first F Galactic radial abundance gradient. Our results are also compared with literature estimates and with Galactic chemical evolution models that have been generated using different F production channels.

    Conclusions. Our results indicate a constant, solar pattern in the [F/Fe] ratios across clusters of different ages, supporting the latest findings that fluorine levels do not exhibit any secondary behavior for stars with solar or above-solar metallicity. However, an exception to this trend is seen in NGC 6791, a metal-rich, ancient cluster whose chemical composition is distinct due to its enhanced fluorine abundance. This anomaly strengthens the hypothesis that NGC 6791 originated in the inner regions of the Galaxy before migrating to its present position. By comparing our sample stars with the predictions of Galactic chemical evolution models, we came to the conclusion that both asymptotic giant branch stars and massive stars, including a fraction of fast rotators that increase with decreasing metallicity, are needed to explain the cosmic origin of F.

    Weak correlation and strong relativistic effects on the hyperfine interaction in fluorine2021In: Physical Review A: covering atomic, molecular, and optical physics and quantum information, ISSN 2469-9926, E-ISSN 2469-9934, Vol. 104, no 6, article id 062813Article in journal (Refereed)
    Abstract [en]

    In previous work devoted to ab initio calculations of hyperfine-structure constants in nitrogen and fluorine atoms, we observed sizable relativistic effects, a priori unexpected for such light systems, that can even largely dominate over electron correlation. We observed that the atomic wave functions calculated in the Breit-Pauli approximation describe adequately the relevant atomic levels and hyperfine structures, even in cases for which a small relativistic LS-term mixing becomes crucial. In the present work we identify levels belonging to the spectroscopic terms 2p(4)(P-3)3d(2,4)(P, D, F) of the fluorine atom, for which correlation effects on the hyperfine structures are small, but relativistic LS-term admixtures are decisive to correctly reproduce the experimental values. The Breit-Pauli analysis of the hyperfine matrix elements nails cases with large cancellation, either between LS pairs for individual hyperfine operators or between the orbital and the spin dipole contributions. Multiconfiguration Dirac-Hartree-Fock calculations are performed to support the Breit-Pauli analysis.

    Cleaning and tailoring the Pt3Sn(111) surface for surface experiments2023In: Surface Science, ISSN 0039-6028, E-ISSN 1879-2758, Vol. 732, article id 122281Article in journal (Refereed)
    Abstract [en]

    The cleaning process of the bimetallic Pt3Sn(111) surface has been studied by means of low-energy electron microscopy (LEEM), microspot low-energy electron diffraction (mu.-LEED), and X-ray photoemission electron microscopy (XPEEM). Different cleaning procedures, performed under ultra-high vacuum conditions (UHV), including sputtering with argon ions and repeated cycles of annealing up to 1500 K were investigated. In this work, we show that a clean Pt3Sn(111) surface of high structural quality with a sharp and brilliant (2 x 2) bulk reconstruction in LEED as well as a perfectly smooth surface with terraces of micron size can be achieved by sputtering, annealing at very high temperatures, followed by a subsequent slow (0.09 K/s) and careful cooling procedure. Additionally, we show the possibility of tailoring the Sn concentration in the topmost layers of Pt3Sn(111) as a function of annealing temperature and subsequent cooling rate. Structural changes of the surface are induced by Sn segregation combined with a surface order-disorder transition at 1340 K. Moreover, two new surface reconstructions depending on the cooling rate are reported.

    Experimental oscillator strengths of Al I lines for near-infrared astrophysical spectroscopy2023In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 672, article id A197Article in journal (Refereed)
    Abstract [en]

    Context. Elemental abundances can be determined from stellar spectra, making it possible to study galactic formation and evolution. Accurate atomic data is essential for the reliable interpretation and modeling of astrophysical spectra. In this work, we perform laboratory studies on neutral aluminium. This element is found, for example, in young, massive stars and it is a key element for tracing ongoing nucleosynthesis throughout the Galaxy. The near-infrared (NIR) wavelength region is of particular importance, since extinction in this region is lower than for optical wavelengths. This makes the NIR wavelength region a better probe for highly obscured regions, such as those located close to the Galactic center.

    Aims. We investigate the spectrum of neutral aluminium with the aim to provide oscillator strengths (f-values) of improved accuracy for lines in the NIR and optical regions (670–4200 nm).

    Methods. Measurements of high-resolution spectra were performed using a Fourier transform spectrometer and a hollow cathode discharge lamp. The f-values were derived from experimental line intensities combined with published radiative lifetimes.

    Results. We report oscillator strengths for 12 lines in the NIR and optical spectral regions, with an accuracy between 2 and 11%, as well as branching fractions for an additional 16 lines.

    Ljus (dagsljus, solljus, utblick &belysning): en kunskapssammanställning2022Report (Other academic)
    Abstract [sv]

    Denna kunskapssammanställning över bland annat regelverk, vägledningar och frivilligakrav för ljus, dagsljus, solljus, utblick och belysning visar att det finns många verktyg attta hjälp av för att styra kvaliteten inom området. Det är viktigt med robusta lösningar försådant som inverkar på människors hälsa.

    Vid stadsförtätning och maximering av markanvändning finns en risk att dagsljusnivåer ibefintliga byggnader minskar kraftigt. Många nya stadsdelar byggs med så hög täthet attdagsljustillgången inte lever upp till dagens krav i alla vistelserum. Kvantitativadagsljuskraven fungerar som en garant för att trender att rationalisera bort tillgång tilldagsljus och utblick inte drivs alltför långt.

    Det finns inslag i moderna byggprojekt som bidrar till lägre energianvändning somsamtidigt leder till lägre dagsljusinsläpp. Minskad fönsterarea ger som konsekvensminskad dagsljusnivå vilken i sin tur får följden att elektrisk belysning måste tändasoftare, särskilt på lägre våningar. Dagsljus är en fri/gratis ljus- och energikälla, sombidrar till resiliens vid elavbrott.

    Elektrisk belysning är ett relativt nytt fenomen. Glödlamporna och lysrören uppfannsomkring 1880 respektive 1930 dvs. för mindre än 150 år sedan. Före dessa uppfinningarvar alla byggnader belysta av dagsljus och byggplanerna och stadsplaneringen ritadesnoggrant för att säkerställa god tillgång till dagsljus.

    Med dagens energi- och elkris är det värt att poängtera att en av de viktigasteenergikällorna (dagsljus) och också styr tidsanpassning och påverkar utvecklingen avalla arter på jorden, inklusive människor, ända ner till cellnivå. Ny forskning publicerasvarje månad som visar hur varje band av den elektromagnetiska strålningen - från UVtill infraröd - är kopplad till dygnsrytmen och att dygnsrytmen är allmänt grundläggandeför hälsa.

    Det är viktigt att byggbranschen håller sig ajour med pågående medicinsk forskning omcirkadiska cykler och hur dagsljus, solljus, utblick och belysning på verkar hälsa.Nya rekommendationer kommer allt tätare.

    Många av de byggtekniska åtgärder som används för att reducera buller påverkardagsljustillgång och till en viss del även utblick negativt. Vid tekniskt samråd är det inteovanligt att akustikkrav väger tyngre än kraven på dagsljus samt utblick.

    Några av de senaste trenderna i utformningen av nya byggprojekt har lett till reduceradedagsljusnivåer inomhus (t.ex. oregelbunden och asymmetrisk placering av fönster,mörka fasadmaterial, avskärmning via fasadelement).

    Elektrisk belysning inomhus behöver utformas för att underlätta seendet, dvs. utanflimmer och bländning. En god visuell miljö minskar mängden ögonbesvär, huvudvärk,muskel och ledbesvär och kan påverka prestationsförmåga och produktivitet på ettpositivt sätt.

    I detaljplaner fastställs förutsättningarna för exploateringsgraden. Byggnadersmöjligheter att uppfylla krav på ljus, dagsljus, solljus och utblick ska prövas.Vid framtagande av detaljplaner är det därför viktigt att se till att kraven är möjliga attuppfyllas. Idag finns många verktyg som också lämpar sig för tidiga skeden, men det ärinte alltid som de tillämpas eller att exploateringsgraden anpassas till resultaten i destudier som görs. Vid hantering först vid startbesked är projekteringsarbetet långtframskridet och anmärkningar skulle få stora konsekvenser.

    När alla rum i kritiska lägen kontrolleras i projekteringen är det vanligt med avvikelserfrån kraven på dagsljusfaktor. En del kan lösas på ritbordet men inte allt. Ibland ärförutsättningarna för svåra och det går inte att hitta lösningar som tillgodoser alla krav.Djupa rum ger svårare förutsättningar än grunda rum, eftersom ljuset avtar kraftigt medavståndet från fönstret.

    I en tätt byggd stad har inte alla samma möjlighet att välja boende – högst upp i huseteller i gathuset där dagsljuset flödar. Mycket få föredrar mörkare bostäder men många ärberedda att kompromissa bort dagsljustillgången för att få tillgång till stadens puls.Dagsljus ska inte bara vara en lyx som privilegierade kan unna sig, det ska vara entillgängligt för alla.

    I tätbebyggda kvarter är det ofta en utmaning att efterleva regelverket. Dagsljuset i Sverige är relativt svagt, och lågt stående sol, dessutom ofta skymd av omgivandebyggnader, ger långa skuggor. Historien visar att svenska städer kan förse alla boendemed ljusa bostäder men om förtätandet fortsätter enligt samma mönster som tidigare såmåste både lagstiftare och planaktörer ha verktyg att förstå dess begränsningar.Misslyckas planeringen av framtidens städer finns en risk att hälsa och välmående för desom bor i den attraktiva kvartersstaden i all mening äventyras.

    Folkhälsomyndigheten och Arbetsmiljöverket utgår från att brist på dagsljus kan genegativa effekter för hälsan. Uppskattningsvis 80 % av levnadstiden spenderas inomhus.Det är en av anledningarna att miniminivåer för dagsljus i vistelserum är nödvändiga ibyggregler.

    Dagsljusfaktorn är ett bra mått för att bedöma tillgången av dagsljus. Dagsljusfaktornbeskrivs i en nyare standard där den bedöms över en yta och inte i en punkt.BBR hänvisar till föråldrade metoder.

    Nuläge termisk komfort: en kunskapssammanställning2022Report (Other academic)
    Abstract [sv]

    Boverket ser ett behov av en kunskapssammanställning kring nuläget inom termisk komfort i Sverige för att ha en så bred och korrekt förståelse som möjligt för vem branschen är, vilka regler som tillämpas, var det finns kunskapscentra och vilka utvecklingsbehov som behöver stödjas för att branschen ska kunna ta större ansvar.

    Några faktafrågeställningar som vi författare noterat och som kan vara värda att kartlägga ytterligare:

    Metoder att simuleraKlimatdata för analyser och simuleringarBetydelsen av värmeöarÅtgärder för att minska värmelaster på byggnaderörbereda plats i byggnader för komfortkylaRisker med fukt och påväxt vid komfortkylaPrioriterade rum för termisk komfortUpplåtelseformers inverkan, utsatta grupper och lokala reglerVädring och fläktarPrioritera passiva åtgärderPortabel luftkylning/komfortkylaTillsyn och bygglovKrav som inte är samordnade (energi, dagsljus, buller, etc.)VarningssystemFörhoppningen är att kartläggning av termisk komfort ska bidra till kunskapsspridning om bransch, aktörer, teknik, system, konstruktion, kontroller, drift och underhåll samt forskning och utveckling.

    Modelling Daily Gross Primary Productivity with Sentinel-2 Data in the Nordic Region-Comparison with Data from MODIS2021In: Remote Sensing, E-ISSN 2072-4292, Vol. 13, no 3, article id 469Article in journal (Refereed)
    Abstract [en]

    The high-resolution Sentinel-2 data potentially enable the estimation of gross primary productivity (GPP) at finer spatial resolution by better capturing the spatial variation in a heterogeneous landscapes. This study investigates the potential of 10 m resolution reflectance from the Sentinel-2 Multispectral Instrument to improve the accuracy of GPP estimation across Nordic vegetation types, compared with the 250 m and 500 m resolution reflectance from the Moderate Resolution Imaging Spectroradiometer (MODIS). We applied linear regression models with inputs of two-band enhanced vegetation index (EVI2) derived from Sentinel-2 and MODIS reflectance, respectively, together with various environmental drivers to estimate daily GPP at eight Nordic eddy covariance (EC) flux tower sites. Compared with the GPP from EC measurements, the accuracies of modelled GPP were generally high (R-2 = 0.84 for Sentinel-2; R-2 = 0.83 for MODIS), and the differences between Sentinel-2 and MODIS were minimal. This demonstrates the general consistency in GPP estimates based on the two satellite sensor systems at the Nordic regional scale. On the other hand, the model accuracy did not improve by using the higher spatial-resolution Sentinel-2 data. More analyses of different model formulations, more tests of remotely sensed indices and biophysical parameters, and analyses across a wider range of geographical locations and times will be required to achieve improved GPP estimations from Sentinel-2 satellite data.

    A comprehensive review on heat accounting and cost allocation in residential buildings in EU2019In: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178, Vol. 202, article id 109398Article in journal (Refereed)
    Abstract [en]

    Since 2002, the European Union (EU) has promoted individual metering of energy consumption as an ef- fective tool to improve energy efficiency in buildings. In 2012, the Energy Efficiency Directive has set mandatory the individual heat accounting in buildings when centralized heating/cooling systems are present, when technically feasible and cost efficient. As a consequence, EU Member States adopted dif- ferent allocation rules mainly due to differences in building stocks and climatic conditions. This measure has led to a series of technical, legal and consumer protection issues which still need to be solved. In this paper, more than 130 publications have been analysed and critically reviewed, highlighting the dif- ferent approaches adopted in EU Member States concerning heat accounting and the related issues. To this aim, the authors focussed the following subjects: (i) the allocation rules adopted by EU Member States, (ii) the heat metering and sub-metering technologies, (iii) the cost-benefit analysis of individual heat metering and accounting systems. This review is useful for researchers since the existing regulation and technologies for heat accounting and their related potential are discussed together with the analysis of the existing gap in terms of technical standard and consumer protection. Finally, the analysis provides policy makers with several suggestions to improve transparency and reliability of allocation rules.
