  1. 1. En sund själ i en sund kropp : hälsopolitik i Stockholms folkskolor 1880-1930

    Författare :Lena Hammarberg; Eva Palmblad; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Discipline; Elementary School; Hygiene; Health Education; School History in Sweden in the 19th century; School History in Sweden in the 20th century; Stockholm: Maria Elementary School.; pedagogik; Education;

    Sammanfattning : A sound mind in a sound body is a study of the health policy in Stockholm's elementary schools. One of the city's schools is used as a representative focus: the Maria Elementary School. The efforts of the school's leadership, medical staff and corps of teachers to create clean and healthy children, are broadly described. LÄS MER

  3. 2. On Multistage Analysis of Transonic Compressors: From Axisymmetric Throughflow Time-Marching to Unsteady Three-Dimensional Methods

    Författare :Stephane Baralon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shock; time-marching; deterministic; average-passage; multistage; fan; axisymmetric; 3D; unsteady; transonic; viscous; body force; stress; singularity; perturbation; throughflow; mixing-plane; modelling; finite-volume;

    Sammanfattning : A throughflow time-marching finite-volume solver, capable of computing viscous transonic multistage compressor flows with embedded shocks, is presented. The behavior of the blade model, based on the blade mean surface flow tangency condition, was investigated for transonic flows. LÄS MER

  4. 3. Numerical approximations of time domain boundary integral equation for wave propagation

    Författare :Andreas Atle; KTH; []
    Nyckelord :MOT; Marching on in time; boundary integral equations;

    Sammanfattning : Boundary integral equation techniques are useful in thenumerical simulation of scattering problems for wave equations.Their advantage over methods based on partial di.erentialequations comes from the lack of phase errors in the wavepropagation and from the fact that only the boundary of thescattering object needs to be discretized.

  5. 4. Approximations of Integral Equations for WaveScattering

    Författare :Andreas Atle; Björn Engquist; Richard Tsai; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integral equations; Marching on in time; On surface radiation condition; Physical Optics; Numerical analysis; Numerisk analys;

    Sammanfattning : Wave scattering is the phenomenon in which a wave field interacts with physical objects. An incoming wave is scattered at the surface of the object and a scattered wave is produced. Common practical cases are acoustic, electromagnetic and elastic wave scattering. LÄS MER

  7. 5. Computation of Thermal Development in Injection Mould Filling, based on the Distance Model

    Författare :Per-Åke Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermoplastic materials; finite element FEM ; finite difference FD ; Newton-Mysovskii theorem; Moldflow Mfl ; Cadmould Cmd ; MATHEMATICS; MATEMATIK;

    Sammanfattning : The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion ([Aronsson], 1996).The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.
