The TRE3 research project focuses on the development of a new and innovative timber frame wall modulus for emergency housing facilities. The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialit
Mainstream option valuation theory relies implicitly on the assumption that latent states (such as stochastic volatility) and parameters are perfectly known, an assumption that is dubious in many ways. Computing the value of options under the assumption of perfect knowledge will typically introduce bias. Correcting for the bias is straightforward but can be computationally expensive. Fourier-base
Hidden Markov models are applied in many expert and intelligent systems to detect an underlying sequence of persistent states. When the model is misspecified or misestimated, however, it often leads to unrealistically rapid switching dynamics. To address this issue, we propose a novel estimation approach based on clustering temporal features while penalizing jumps. We compare the approach to spect
A number of measures have been taken by the society to ensure gender equality in higher education. Nevertheless, women still face great difficulties when pursuing an academic career. Our aim is to increase the understanding of how the society, conceptualised as the organisational field, interacts with organisational factors and personal actions as women try to establish themselves within academia.
Popular Abstract in Swedish Barn födda före 32 gestationsveckor, även de utan svåra neurologiska avvikelser, har en hög förekomst av neuropsykologiska problem såsom läs-, inlärnings-, språk-, minnes- och beteendeproblem. Det är ännu inte klarlagt vilka funktionella och strukturella förändringar i hjärnan som orsakar dessa problem. Möjligheten till tidig diagnos behövs men saknas ännu. Auditiva hänChildren born before 32 gestational weeks have a high incidence of neuropsychological deficits. The structural and functional correlates of such impairments in preterm infants are incompletely understood, and early diagnostic tools are needed, but still lacking. Auditory event-related potentials (AERPs) are neurophysiological measures of cortical sound detection, encoding, discrimination, and atte
Snow in the environment acts as a host to rich chemistry and provides a matrix for physical exchange of contaminants within the ecosystem. The goal of this review is to summarise the current state of knowledge of physical processes and chemical reactivity in surface snow with relevance to polar regions. It focuses on a description of impurities in distinct compartments present in surface snow, suc
Sustainability, resilience and safety are features of a society that are more affected by sound environments than is generally acknowledged, even if other environmental threats may appear more prominent. But when noise levels reach the limits of sustainability in society, it´s resilience to destructive processes of many kinds will be challenged. In an interdisciplinary symposium in 2014 arranged b
Aggregation of the amyloid β-protein (Aβ) is believed to be involved in Alzheimer's disease pathogenesis. Here we have investigated the importance of the aromatic rings at positions 19 and 20 for the aggregation rate and mechanism by substituting phenylalanine with leucine. Aggregation kinetics were monitored as a function of time and peptide concentration by thioflavin T (ThT) fluorescence, the a
Data are presented on the number of fibers and the proportion of different fiber types within fascicles of whole vastus lateralis muscles from 5 male children, 5 to 15 years of age, and compared with results from 25 male adults, middle aged and old individuals. The results verify a difference in the proportion of fibers with different properties within a fascicle. The proportion of type 2 (fast tw
In an effort to find conditions favouring bioelectrocatalytic reduction of oxygen by surface-immobilised human ceruloplasmin (Cp), direct electron transfer (DET) reactions between Cp and an extended range of surfaces were considered. Exploiting advances in surface nanotechnology, bare and carbon-nanotube-modified spectrographic graphite electrodes as well as bare, thiol- and gold-nanoparticle-modi
The following thesis is examining compliance with EU-law from a member state perspective. The variation in the compliance level between the member states from 1995 to 2005 is analyzed to prove the fact that the Nordic member countries during the measured time period experienced a low number of infringements. The infringements that did occur were resolved faster and more efficient in the Nordic cou
We investigated the role of attention and executive control in rhythmic timing, using a dual-task paradigm. The main task was a finger tapping task in which participants were asked to tap their index finger in time with metronome sequences. The tempo of the sequences ranged from 600 ms to 3000 ms between each beat. The distractor task, chosen so as to engage executive control processes, was a nove
Efficient and robust control strategies can greatly contribute to the reliability of fuel cell systems, and a stable output voltage is a key criterion for evaluating a fuel cell system's reliability as a power source. In this study, a polymer electrolyte fuel cell (PEFC) system model is developed, and its performances under different operating conditions are studied. Then two different novel contr
The effects of ionizing radiation in different compositions of polymer gel dosimeters are investigated using FT-Raman spectroscopy and NMR T2 relaxation times. The dosimeters are manufactured from different concentrations of comonomers (acrylamide and N,N'-methylene-bis-acrylamide) dispersed in different concentrations of an aqueous gelatin matrix. Results are analysed using a model of fast exchan
