  1. 16. Third Party Logistics : Outsourcing Logistics in Partnerships

    Författare :Dan Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Third-Party Logistics; Contract Logistics; Outsourcing; Partnerships; Operational Alliances; Physical Distribution; Materials Management;

    Sammanfattning : The purpose of this dissertation is to contribute the body of knowledge of the outsourcing of logistics services in integrated relationships between a shipper ( e.g. a manufacturer) and a logistics service provider (e.g. LÄS MER

  3. 17. VCSELs for High-Speed, Long-Reach, and Wavelength-Multiplexed Optical Interconnects

    Författare :Erik Haglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mode filter; high-contrast grating; oxide aperture; high-speed modulation; wavelength control; spectral width; vertical-cavity surface-emitting laser; optical interconnect; quasi-single-mode;

    Sammanfattning : The vertical-cavity surface-emitting laser (VCSEL) is the standard light source in short-reach fiber-optic links in datacenters and supercomputers. These systems use an enormous number of links, making cost and energy efficiency pressing issues. LÄS MER

  4. 18. Respiratory mechanics during mechanical ventilation in health and in disease

    Författare :Cecilia Svantesson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Recruitment; Collapse; Overdistension; Viscoelasticity; Elastic pressure-volume curve; Respiratory disease; Health; Human; Rabbit; Positive end-expiratory pressure; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : The elastic pressure-volume (Pel-V) curve of the respiratory system can be used as a guide for improved ventilator management. It may indicate risks of lung damage associated with collapse or overdistension of lung units. LÄS MER

  5. 19. Medical CT-scanners for non-destructive wood density and moisture content measurements

    Författare :Owe Lindgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Most methods to measure wood density and moisture content are destructive. One non-destructive technique is X-ray computed tomography (CT). The actual physical variable measured is the X-ray linear attenuation coefficient which is highly density dependent. LÄS MER

  7. 20. Methods for Reducing the Complexity of Geometrical Structures Based on CFD Programming : Time Efficient Simulations Based on Volume Forces Coupled with Single and Two-phase Flow

    Författare :Kamal Rezk; Lars Nilsson; Jonas Berghel; Erik Dahlquist; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical design cycle; CFD; porous media; volume forces; heat exchanger; vacuum dewatering; time efficient simulations; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Throughout recent years, computer based programs have been applied to solve and analyse industrial problems encountered global fields such as automobile design for reduction of CO2-gas, designing wind parks aimed at increasing power output etc. One of these developed programs is Computational Fluid Dynamics (CFD) which numerically solves complex flow behaviour based on computer power.
