Popular Abstract in Swedish Doktorsavhandlingen handlar om beslutsfattande i grupp och innehåller studier om efterbeslutsprocesser. Gruppmedlemmar i olika experimentellt skapade sociala situationer jämförs med individuella beslutsfattare. Metoden är alltså i huvudsak experimentell, men en kvalitativ metod har också använts för att studera kommunikationen under gruppdiskussionerna. Studierna använThe present thesis examines differences in post-decision processes between members of groups and individual decision makers. The empirical studies employed a decision theoretical framework based on Differentiation and Consolidation (Diff Con) Theory. Diff Con theory proposes that decision makers strive to achieve sufficient differentiation in their evaluation of one alternative versus competing al

The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. The performance of iterative decoding depends on the quality of the extrinsic inputs; badly correlated extrinsic inputs can deteriorate the performance. While most turbo coding literature assumes that the extrinsic information is uncorrelated, we investig

Popular Abstract in Swedish Olika sätt att mäta substrat (monosackarider) och produkter (främst etanol) vid tillverkning av biobränslet etanol har studerats. Etanoltillverkning sker i en fermentor med hjälp av mikroorganismer som kan omvandla socker. Det är av stort intresse att mäta koncentrationen av produkter och substrat under tillverkningsprocessens gång för att veta om den fortlöper som den

Popular Abstract in Swedish I detta arbete har utvecklats automatiserade system för analys av miljöprover och av biologiska material. Två olika membranbaserade provupparbetningsmetodiker har använts för provförberedelse tillsammans med olika typer av kromatografi för själva analysen. Dessa principer har applicerats på tre olika tillämpningsområden. Extraktion med vätskemembran har kopplats med et

The electromagnetic scattering properties of red blood cells were analyzed by three different methods. The finite-different time-domain method is a general and flexible approach and enables accurate simulations of scattering from objects with arbitrary shape. This method was compared with two approximate methods: the Rytov approximation and the Discrete Dipole Approximation. The interaction of light

BiPd is a noncentrosymmetric superconductor with Dirac-like surface states on both (010) and (01¯0) faces. The Dirac cone on (010) surface is intense and appears at 0.66 eV binding energy. These states have drawn much attention due to contradictory reports on dimensionality and the momentum of these Dirac fermions. We have studied the properties of these Dirac fermions using varied photon energies

The purpose of this study was to investigate the effects of experimental data on performance of a developed Bayesian algorithm tailored for orphan source search, estimating which parameters affect the accuracy of the algorithm. The algorithm can estimate the position and activity of a gamma-ray point source from experimental mobile gamma spectrometry data. Bayesian estimates were made for source p

Traffic models can be used to study evacuation scenarios during wildland-urban interface fires and identify the ability of a community to reach a safe place. In those scenarios, wildfire smoke can reduce visibility conditions on the road. This can have serious implications on the evacuation effectiveness since drivers would reduce their speed in relation to the optical density on the road. To date

Purpose: To investigate long-term trends and changes in the pattern of use of lamotrigine (LTG). Methods: Retrospective survey of a large, routine therapeutic drug monitoring database. Results: Twelve thousand one hundred and seven samples from 4123 subjects were analysed from October 1999 to May 2007. Within this period, the mean daily dose rose from 183 to 253 mg, whereas the median dose remaine

Purpose: To study the interaction between lamotrigine (LTG) and hormonal contraception. Methods: LTG serum concentrations of female patients using either no hormonal contraception (n = 18), an ethinyl estradiol (EE)-containing (n = 11), or a progestogen (PG)-only-containing compound (n = 16) were analyzed. Patients were recruited prospectively, and blood samples were drawn during drug fasting and

Digital twins have been gaining an immense interest in various fields over the last decade. Bringing conventional process simulation models into (near) real time are thought to provide valuable insights for operators, decision makers, and stakeholders in many industries. The objective of this paper is to describe two methods for implementing digital twins at water resource recovery facilities and

The term “charisma” is recognized as sociology's most successful export to common speech. While sociologists habitually dismiss popular uses of the word, we address its vernacularity head on as a worthy object of study and as a potential resource for conceptual development. Using machine learning, we locate “charisma” within the wider discursive field out of which it arises (and continues to arise

Care robots are often portrayed as an exciting new technology for improving care practices. Whether these robots will be accepted and integrated into care work or not, is likely to be affected by the assumptions, expectations and understandings held by potential end users, such as frontline staff and the people that are cared for. This paper describes how the conceptual framework of technological

The classical problem of the Hebrew consecutive tenses is here attacked from a different angle: that of comparative language typology. The article explores parallel typological developments between West Semitic and early Indo-European as pertains to the creation of verbal forms by means of adding an “augment” or temporalizing particle to otherwise Aktionsart- or aspect-based morphological construc

What factors affects New Product Development (NPD) and are the factors the same in different industries? These are two of the main questions explored when three organizations in different industries are studied from the perspectives of knowledge, motivation and organizational context. Focus is on the early phases of NPD, however the entire NPD process is included to better understand the results o

Two recent dynamic friction models, the LuGre model and a model by Bliman and Sorine, are investigated and compared. Comparisons are made of captured friction phenomena, behaviour at zero crossings of the velocity and computational issues. Limit cycles in position control of a simple servo with dynamic friction are investigated by means of single input describing function analysis. Both models giv
