  1. 21. Heat Transfer Prediction of In Service Welding in a Forced Flow of Fluid

    Författare :Per Lindström; Lars-Erik Svensson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sjöfartsvetenskap; Maritime Science;

    Sammanfattning : An algorithm for heat transfer prediction of in-service welding operations in a forcedflow of fluid is presented. The algorithm presented is derived from Rosenthal’s 3D heatflow equation and boundary layer approximations. LÄS MER

  3. 22. Improved CWM platform for modelling welding procedures and their effects on structural behaviour

    Författare :Per Lindström; Lars-Erik Svensson; Lennart Josefson; Hannu Hänninen; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CWM; FEM; WELD; STRESS; EPFM; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : A welding procedure specification is the document describing how a weld joint should be constructed. Arc weld processes are characterized by transient thermal behavior, leading to rapid changes in material properties and dynamic interaction between weld and base material. LÄS MER

  4. 23. Ultrasound Assessment and Vascular Mechanics in Takayasu Arteritis and Systemic Lupus Erythematosus

    Författare :Christina Svensson; Helene Zachrisson; Christopher Sjöwall; Per Eriksson; Andreas P. Diamantopoulos; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Takayasu arteritis (TAK) and systemic lupus erythematosus (SLE) are inflammatory diseases that primarily affect young women. TAK is a rare vasculitis that affects the aorta and its main branches, whereas SLE is a chronic autoimmune disease that effects multiple organs. LÄS MER

  5. 24. Topics in Workforce Management in a Contact Center Context

    Författare :Göran Svensson; Per Enqvist; Tolga Tezcan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; queues; queuing networks; workforce management; optimization; conditional value-at-risk; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This thesis is written as a monograph covering topics in operations research and focusing on workforcemanagement in a contact center environment.This text is the result of a cooperative project between the Royal Institute of Technology (KTH) andTeleopti WFM. LÄS MER

  7. 25. Carbon dynamics in spruce forest ecosystems - modelling pools and trends for Swedish conditions

    Författare :Magnus Svensson; Per-Erik Jansson; Dan Berggren Kleja; Keith Paustian; KTH; []
    Nyckelord :boreal; climate; CoupModel; net ecosystem production; nitrogen; process-based model; soil carbon; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Carbon (C) pools and fluxes in northern hemisphere forest ecosystems are attracting increasing attention concerning predicted climate change. This thesis studied C fluxes, particularly soil C dynamics, in spruce forest ecosystems in relation to interactions between physical/biological processes using a process-based ecosystem model (CoupModel) with data for Swedish conditions.
