2. 6. Characterization of energy gases by ultrasound : theory and experiments

   Author : Pär-Erik Martinsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

   Abstract : The long-term goal with the research presented in this thesis has been to develop an ultrasonic sensor capable of measuring the energy content of energy gases such as natural- and biogas. The energy content can be calculated if the concentration of each constituent of a gas mixture is known. READ MORE

4. 7. Essays on Econometric Theory

   Author : Peter Jochumzen; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic theory; econometrics; Economics; measure of fit; unemployment insurance; non proportionality; stochastic frontier production function; diffusion of technology; Duration analysis; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

   Abstract : This dissertation contains a variety of contributions to econometric theory. Broadly speaking, econometrics may be categorized depending on what type of data is being analyzed, the two main categories being time series data and cross sectional data. A third category is panel data, combining cross sectional data observed over time. READ MORE

5. 8. String Theory at the Horizon : Quantum Aspects of Black Holes and Cosmology

   Author : Martin Olsson; Ulf Danielsson; Lárus Thorlacius; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; black holes; cosmology; de Sitter space; c=1 matrix models; 2D string theory; topological string theory; conifolds; 4D BPS black holes; Gödel universe; closed time-like curves; Teoretisk fysik; Physics; Fysik;

   Abstract : String theory is a unified framework for general relativity and quantum mechanics, thus being a theory of quantum gravity. In this thesis we discuss various aspects of quantum gravity for particular systems, having in common the existence of horizons. READ MORE

6. 9. Estimation of Nonlinear Dynamic Systems : Theory and Applications

   Author : Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

   Abstract : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. READ MORE

7. 10. Norm-Regulation of Agent Systems : Instrumentalizing an algebraic approach to agent system norms

   Author : Magnus Hjelmblom; Magnus Boman; Jan Odelstad; Kim Solin; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agent System; Norm-regulated; Norm-governed; Normative MAS; Normative Positions; Normative system; Transition system; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : An architecture for norm-regulated multi-agent systems based on an algebraic approach to normative systems is instrumentalized and further developed. The core of the instrumentalization is a Prolog module, which together with a Java library can be used for creating client/server-based runtime systems. READ MORE
