  1. 1. Numerical Computations with Fundamental Solutions

    Författare :Per Sundqvist; Henrik Brandén; Sverker Holmgren; Alison Ramage; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fundamental solution; partial differential equation; partial difference equation; iterative method; preconditioner; boundary method; Numerical Analysis; Numerisk analys;

    Sammanfattning : Two solution strategies for large, sparse, and structured algebraic systems of equations are considered. The first strategy is to construct efficient preconditioners for iterative solvers. The second is to reduce the sparse algebraic system to a smaller, dense system of equations, which are called the boundary summation equations. LÄS MER

  3. 2. Production Costs Calculation Model in Crushing and Screening : Using a technical-economic approach tool for finding the optimal production costs when comparing technical and economical solutions

    Författare :Per Hedvall; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Krossning; siktning; sortering; krossanläggningar; processer; produkter; kostnad; entreprenadindustri; Gruvindustri; ballastindustri; beräkningar;

    Sammanfattning : The mining and quarrying industries represent a highly important sector of the Swedish economy. The mining industry operates globally, whereas the quarrying industry operates on a regional/local basis. LÄS MER

  4. 3. Computational methods for cellular network inference and compound evaluation

    Författare :Kristofer Hallén; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Most diseases are caused by a mixture of environmental and genetic components. The genetic component is mainly inherited but can also induced by the environment. Cancer and cardiovascular diseases are not affected by a single gene but more often by a number of genes a nd also the complex system that the interactions between these genes form. LÄS MER

  5. 4. Gene Expression Profiling of Human Atherosclerosis

    Författare :Sara Hägg; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Atherosclerosis is the main underlying cause of coronary artery disease (CAD) and stroke. These two diseases are leading causes of death in the developed world. The socio-economical cost for treatments and absence of work is enormous. Recent numbers from the US show no tendency of decline in the spread of atherosclerosis. LÄS MER

  7. 5. Gene Expression Profiling of Human Atherosclerosis

    Författare :Sara Hägg; Johan Björkegren; Jesper Tegnér; Josefin Skogsberg; Olle Melander; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Atherosclerosis is a progressive inflammatory disease that causes lipid accumulation in the arterial wall, leading to the formation of plaques. The clinical manifestations of plaque rupture—stroke and myocardial infarction—are increasing worldwide and pose an enormous economic burden for society. LÄS MER
