  3. 2. Optimization product parts in high pressure die casting process

    Författare :Mohammad Sadeghi; Rebei Bel-fdhila; Dan Loyd; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Sammanfattning : This thesis describes optimization of die temperature in high pressure die-casting (HPDC) of A380 alloy by experimental observation and numerical simulation with the use of statistical tools. The goal of this research is to determine the optimum die temperature to minimize incidence of these defects and thus maximize production of parts without defects. LÄS MER

  4. 3. Analysis and Management of Communication in On-Chip Networks

    Författare :Fahimeh Jafari; Ahmed Hemani; Davide Bertozzi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Regarding the needs of low-power, high-performance embedded systems and the growing computation-intensive applications, the number of computing resources in a single chip has enormously increased. The current VLSI technology is able to support such an integration of transistors and add many computing resources such as CPU, DSP, specific IPs, etc to build a Systemon- Chip (SoC). LÄS MER

  5. 4. Influence of optical properties on Laser Doppler Flowmetry

    Författare :Marcus Larsson; Stefan Andersson-Engels; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser Doppler flowmetry (LDF) is based on the principle that a Doppler shift occurs when coherent light is scattered by a moving object, i.e. red blood cell (RBC). The magnitude of these frequency shifts affects the optical beating that occurs w hen shifted and non-shifted light is mixed. LÄS MER
