  1. 1. Dimension Reduction and Signal Decomposition for Genotype–Phenotype Relations

    Författare :Rasmus Perby Henningsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Bioinformatik; Dimensionsreduktion; Computational mathematics; Bioinformatics; Dimension reduction;

    Sammanfattning : Over the last few decades, DNA sequencing has developed from costing billions of dollars to get the complete sequence of the human genome, to being a routine procedure performed in labs all around the world. This has transformed the field of experimental biology since measurements can be done at a level of detail that was not possible before. LÄS MER

  4. 3. Efficient reduction techniques for a large-scale Transmission Expansion Planning problem

    Författare :Quentin Ploussard; Luis Olmos; Andres Ramos; Efraim Centeno; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy; electricity; transmission expansion planning; linear programming; integer linear programming; relaxation methods; clustering; dimension reduction; network theory graphs ; partitioning algorithms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The aim of Transmission Expansion Planning (TEP) studies is to decide which, where, and when new grid elements should be built in order to minimize the total system cost. The lumpiness of the investment decisions, together with the large size of the problem, make the problem very hard to solve. LÄS MER

  5. 4. On Dimension Reduction in Sensor Array Signal Processing

    Författare :Sören Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the last decades, sensor array signal processing has been a very active research area. More recently, relations between many of the proposed methods has been examined. The problem of assessing the estimation accuracy of these methods has also been addressed. LÄS MER

  7. 5. Scaling effects and homogenization of reaction-diffusion problems with nonlinear drift

    Författare :Vishnu Raveendran; Adrian Muntean; Irina Pettersson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homogenization; asymptotic expansion with drift; two-scale convergence with drift; effective transmission condition; dimension reduction; two-scale system; nonlinear dispersion; Matematik; Mathematics;

    Sammanfattning : We study the periodic homogenization of reaction-diffusion problems with nonlinear drift describing the transport of interacting particles in composite materials. The microscopic model is derived as the hydrodynamic limit of a totally asymmetric simple exclusion process for a population of interacting particles crossing a domain with obstacles.
