2. 1. Skew-symmetric matrix pencils : stratification theory and tools

   Author : Andrii Dmytryshyn; Bo Kågström; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Investigating the properties, explaining, and predicting the behaviour of a physical system described by a system (matrix) pencil often require the understanding of how canonical structure information of the system pencil may change, e.g., how eigenvalues coalesce or split apart, due to perturbations in the matrix pencil elements.

4. 2. REMAP-γ: A Scalable SIMD VLSI Architecture with Hierarchical Control

   Author : Lars Bengtsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; array signal processing; hierarchical control; SIMD; VLSI architectures; distributed synchronous clocking; embedded supercomputing;

   Abstract : While the clock speed of general purpose (uni-)processors has risen dramatically during recent years, this is not true for SIMD (Single Instruction stream Multiple Data streams) parallel processors. The reason is to be found in the structure of this type of architecture: long-range broadcasting of data, clock and control signals. READ MORE

5. 3. Tools for Structured Matrix Computations : Stratifications and Coupled Sylvester Equations

   Author : Andrii Dmytryshyn; Bo Kågström; Volker Mehrmann; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Developing theory, algorithms, and software tools for analyzing matrix pencils whose matrices have various structures are contemporary research problems. Such matrices are often coming from discretizations of systems of differential-algebraic equations. READ MORE

6. 4. Essays on Consumption : - Aggregation, Asymmetry and Asset Distributions

   Author : Mårten Bjellerup; Jan Ekberg; Katarina Juselius; Växjö universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aggregate consumption; Aggregation; Asymmetry; Wealth distribution; Income distribution; Concavity; Permanent Income Hypothesis; Buffer stock saving; Precautionary saving; consumption; saving; Euler equation; error correction; skew-t distribution; gamma distribution; dispersion; non-linear model; durable goods; nondurable goods; household level data; consumption function; marginal propensity to consume; current resources; consumption expenditure; life-cycle model; univariate test; multivariate test; Sweden; Economics; Nationalekonomi; Economics; Nationalekonomi;

   Abstract : The dissertation consists of four self-contained essays on consumption. Essays 1 and 2 consider different measures of aggregate consumption, and Essays 3 and 4 consider how the distributions of income and wealth affect consumption from a macro and micro perspective, respectively.

7. 5. Human leukocyte antigen in sickness and in health : Ankylosing spondylitis and HLA in Sweden

   Author : Jessika Nordin; Kerstin Lindblad-Toh; Jennifer Meadows; Matthew Webster; Alison Meynert; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Disease genetics; Ankylosing spondylitis; HLA typing; Imputation; Inference; Sex-stratified; HLA-B*27 independent; Association tests; Functional validation; Bioinformatics; Bioinformatik; Molekylär genetik; Molecular Genetics;

   Abstract : The human leukocyte antigen (HLA) plays a major role in keeping us healthy, but some of the HLA alleles can contribute to disease susceptibility. One example is HLA-B*27, which confers increased susceptibility of ankylosing spondylitis and represents one of the strongest genetic associations found in any common human disease. READ MORE
