    Sammanfattning : Essay 1 studies the household's decision to supply labor and tests if the so-called unitary model holds. What is subject to a test is the resulting symmetry of the Slutsky matrix, i.e., that the compensated cross-wage effects are equal. LÄS MER

  2. 2. Assessment of cerebrospinal fluid system dynamics novel infusion protocol, mathematical modelling and parameter estimation for hydrocephalus investigations

    Detta är en avhandling från Umeå : Umeå university

    Författare :Kennet Andersson; Anders Eklund; Karin Wårdell; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknik; hydrocefalus; infusionstest; utflödeskonduktans; systemidentifiering; MEDICINE Physiology and pharmacology Physiology Medical technology; MEDICIN Fysiologi och farmakologi Fysiologi Medicinsk teknik;

    Sammanfattning : Patients with idiopathic normal pressure hydrocephalus (INPH) have a disturbance in the cerebrospinal fluid (CSF) system. The treatment is neurosurgical – a shunt is placed in the CSF system. The infusion test is used to assess CSF system dynamics and to aid in the selection of patients that will benefit from shunt surgery. LÄS MER

  3. 3. High Order Finite Difference Methods with Artificial Boundary Treatment in Quantum Dynamics

    Detta är en avhandling från Umeå : Umeå university

    Författare :Anna Nissen; Gunilla Kreiss; Sverker Holmgren; Magnus Svärd; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schrödinger equation; finite difference methods; perfectly matched layer; summation-by-parts operators; adaptive discretization; stability; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The investigation of the dynamics of chemical reactions, both from the theoretical and experimental side, has drawn an increasing interest since Ahmed H. Zewail was awarded the 1999 Nobel Prize in Chemistry for his work on femtochemistry. LÄS MER

  4. 4. Analysis of boundary and interface closures for finite difference methods for the wave equation

    Detta är en avhandling från Uppsala University

    Författare :Siyang Wang; Gunilla Kreiss; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : We consider high order finite difference methods for the wave equations in the second order form, where the finite difference operators satisfy the summation-by-parts principle. Boundary conditions and interface conditions are imposed weakly by the simultaneous-approximation-term method, and non-conforming grid interfaces are handled by an interface operator that is based on either interpolating directly between the grids or on projecting to piecewise continuous polynomials on an intermediate grid.

  5. 5. Residual Generation Methods for Fault Diagnosis with Automotive Applications

    Detta är en avhandling från Linkö : Linköping University Electronic Press

    Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik Systemteknik;

    Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER
