Representing a physical system with a mathematical model requires knowledge not only about the physical laws governing the dynamics but also about the parameter values of the system. The parameters can sometimes be measured or calculated, however some of them are often difficult or impossible to obtain in these ways. Finding accurate parameter values is crucial for the accuracy of the mathematical

Popular Abstract in Swedish Om man betraktar ljuset fran en varm gas ser man att det har en viss färg som är beroende gasens kemiska sammansättning. Består gasen av endast ett ämne kan man genom att detaljstudera ljuset erhålla information som är specifik för just detta grundämnet. For varje grundämne finns ett mönster av spektrallinjer som bygger upp ämnets spektrum. Om spektrumen for många ämnenInvestigation of astrophysical plasmas, such as stellar atmospheres, require both knowledge of atomic structure and data. We present laboratory instruments, techniques and tools for acquisition of the data required to derive important atomic parameters such as, wavelengths, oscillator strengths and line profiles. In this thesis new atomic data for advancement of stellar atmosphere analysis are pre

”Det är en jättegrej det här att bli sedd som elitidrottare” - Citatet är från en intervju med en kvinnlig idrottare, en ung kvinna som är bland de bästa i världen i sin gren, bordtennis. Hur är det att vara funktionshindrad kvinna i idrottens världselit? - Vikten i analysen läggs vid situationens motsägelsefullhet: Att vara bland de bästa i något som är socialt marginaliserat och som befinner sig

This paper discusses a method for abnormal motion detection and its real-time implementation on a smart camera. Abnormal motion detection is a surveillance technique that only allows unfamiliar motion patterns to result in alarms. Our approach has two phases. First, normal motion is detected and the motion paths are trained, building up a model of normal behaviour. Feed-forward neural networks are

Boken är producerad inom Etikforskningsprogrammet i anslutning till Swegene och Wallenberg Consortium North (WCN). Birgitta Forsman skriver om sekulära perspektiv på människan och gentekniken. Tre olika religiösa förhållningssätt beskrivs och analyseras: judiska (Karin Hedner Zetterholm), kristna (Axel Carlberg), och muslimska (Jonas Svensson). Ställningstagandena till de aktuella bioetiska frågor

Data from Au+ Au interactions at s(NN)=130 GeV, obtained with the PHENIX detector at the Relativistic Heavy-Ion Collider, are used to investigate local net charge fluctuations among particles produced near midrapidity. According to recent suggestions, such fluctuations may carry information from the quark-gluon plasma. This analysis shows that the fluctuations are dominated by a stochastic distrib

The question of the relation between the collective and the individual has had a long but patchy history within both philosophy and psychology. In this chapter we consider some arguments that could be adopted for the primacy of the we, and examine their conceptual and empirical implications. We argue that the we needs to be seen as a developing and dynamic identity, not as something that exists fu

In this thesis, models for simulation of inelastic phenomena, such as plastic anisotropy, texture evolution, void growth and phase transformation are presented. Special emphasized is put on the modeling of heat generation due to plastic work. All models are formulated within a thermodynamic framework that allows large deformations. The thermodynamic framework is used as a base for the formulation
