  1. 1. High Order Local Radial Basis Function Methods for Atmospheric Flow Simulations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Lehto; Uppsala universitet.; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radial basis function; meshless method; high order finite difference; atmospheric flow; hyper-viscosity; stable algorithm; Scientific Computing; Beräkningsvetenskap;

    Abstract : Since the introduction of modern computers, numerical methods for atmospheric simulations have routinely been applied for weather prediction, and in the last fifty years, there has been a steady improvement in the accuracy of forecasts. Accurate numerical models of the atmosphere are also becoming more important as researchers rely on global climate simulations to assess and understand the impact of global warming. READ MORE

  2. 2. Stem cell function and organ development analysis of Lhx2 function in hematopoietic stem cells and eye development

    University dissertation from Umeå : Umeå university

    Author : Lina Dahl; Umeå universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lhx2; hematopoietic system; hematopoietic stem cell; progenitor; embryonic stem cell; embryoid body; eye development; forebrain; eye field transcription factor; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Molecular medicine genetics and pathology ; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Molekylär medicin genetik och patologi ; molekylär medicin genetik och patologi ; Molecular Medicine;

    Abstract : When a multicellular organism suffers damages to tissues/organs it heals itself by either substituting the lost cellular matrix by scar formation or by regenerating the lost tissue. Regeneration likely occurs by a recapitulation of the developmental process that formed the organ. READ MORE

  3. 3. Radial basis function methods for pricing multi-asset options

    University dissertation from Uppsala universitet

    Author : Victor Shcherbakov; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The price of an option can under some assumptions be determined by the solution of the Black–Scholes partial differential equation. Often options are issued on more than one asset. In this case it turns out that the option price is governed by the multi-dimensional version of the Black–Scholes equation. READ MORE

  4. 4. Study of ergodicity of p-adic dynamical systems with the aid of van der Put basis

    University dissertation from Växjö, Sweden : Linnaeus University

    Author : Ekaterina Yurova; Linnéuniversitetet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; p-adic numbers; van der Put basis; 1-Lipschitz; measure-preserving; ergodicity; sphere; T-function; Tillämpad matematik; Applied Mathematics;

    Abstract : The study of p-adic dynamical systems is motivated by their applications in various (and surprisingly diverse) areas of mathematics, e.g., in physics, genetics, biology, cognitive science, neurophysiology, computer science, cryptology, etc. READ MORE

  5. 5. Gender differences in chemosensory function

    University dissertation from Umeå : Institutionen för psykologi

    Author : Jonas Olofsson; Umeå universitet.; [2005]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Social sciences Psychology; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi; Psychology; psykologi;

    Abstract : This thesis consists of two studies, in which gender differences in nasal chemosensory function are investigated. The first study assesses odor identification ability in a populationbased sample, varying from 45 to 90 yrs, screened for cognitive impairment and severe olfactory dysfunction. READ MORE
