2. 1. Approximating Stochastic Partial Differential Equations with Finite Elements: Computation and Analysis

   Author : Andreas Petersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lévy process; Lyapunov equation; white noise; finite element method; multilevel Monte Carlo; Monte Carlo; multiplicative noise; asymptotic mean square stability; stochastic heat equation; covariance operator; weak convergence; generalized Wiener process; numerical approximation; stochastic wave equation; Stochastic partial differential equations;

   Abstract : Stochastic partial differential equations (SPDE) must be approximated in space and time to allow for the simulation of their solutions. In this thesis fully discrete approximations of such equations are considered, with an emphasis on finite element methods combined with rational semigroup approximations. READ MORE

4. 2. Efficiency in Education - A Multilevel Analysis

   Author : Staffan Waldo; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; economic theory; econometrics; Data Envelopment Analysis; Economics; Education; Efficiency;

   Abstract : Sweden spends altogether about 4.5% of GDP on primary, secondary and upper secondary school. Considering the magnitude of this investment it is important that these resources are used efficiently. In this thesis efficiency in public education is analysed on three different levels: The municipal level, the school level, and the individual level. READ MORE

   Abstract : The thesis comprises four independent research papers and a summary that focus on two related dimensions. The first dimension focuses on the understanding of the production of health. Particularly, the question is asked whether community's stock of social capital influence individual's health. READ MORE

6. 4. Analysis of Some Convolutional Coding Constructions

   Author : Karin Engdahl; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo-codes; low-density parity-check convolutional codes; low-density codes; PSK; PAM; QAM; coded modulation; multilevel coding; convolutional codes; multilevel modulation; iterative decoding; Informatics; systems theory; Informatik; systemteori;

   Abstract : This thesis focuses on different convolutional coding constructions for digital communication systems, and on methods to analyze these constructions. The work presented in the thesis can be divided into three main areas; error probability bounds for convolutional codes, analysis of multilevel modulation, and investigation of low-density parity-check convolutional codes.

7. 5. On Linguistic and Discursive Constructions of Concession and Adversativity : Towards a Multilevel Analysis of English in the UK Parliament

   Author : Mihai Daniel Frumuselu; Michal Krzyżanowski; Cornelia Ilie; Per Ledin; Eivind Nessa Torgersen; Örebro universitet; []
   Keywords : HUMANIORA; HUMANITIES; concession; adversativity; political discourse; parliamentary discourse; UK Parliament; Corpus Linguistics; Discourse Analysis; Critical Discourse Analysis; English; Engelska;

   Abstract : This study analyses concessive and adversarial language in UK parliamentary debates and thereby enriches the theoretical and analytical body of knowledge on the language of concession and adversativity in contemporary English. It contributes to existent scholarship on both grammatical constructions of concession/adversativity and on the dynamics of contemporary British parliamentary and political discourse. READ MORE
