  1. 1. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Författare :Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Sammanfattning : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. LÄS MER

  3. 2. Fabrication, Simulation and Performance of Ultra-Thin Silicon Detectors-Development of a Detection System for Living Cell Irradiation

    Författare :Naseem Salim; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Abdel; micro-fabrication technology; ultra-thin silicon detector; single ions; SIHF; ΔE detector;

    Sammanfattning : For the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. LÄS MER

  4. 3. Investigation of New Concepts and Solutions for Silicon Nanophotonics

    Författare :Zhechao Wang; Lech Wosinski; Kresten Yvind; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Planar integrated circuit; silicon photonics; slot waveguide; finite-difference time-domain; waveguide grating coupler; ring resonator; polarization diversity scheme; polarization beam splitter; polarization rotator; hybrid silicon laser; epitaxial lateral overgrowth; chemical-mechanical polishing.; Optics; Optik;

    Sammanfattning : Nowadays, silicon photonics is a widely studied research topic. Its high-index-contrast and compatibility with the complementary metal-oxide-semiconductor technology make it a promising platform for low cost high density integration. LÄS MER

  5. 4. Microstructure Evolution and Mechanical Properties of Haynes 282

    Författare :Ceena Joseph; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER

  7. 5. New tools for probing biological extremes of ionizing radiation

    Författare :Charlotta Nilsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:000;

    Sammanfattning : Three different biological extremes of irradiation of living organisms, both human and animal, have been investigated and are presented in this thesis. Central to the thesis is the concept of bystander effects of ionizing radiation, i.e. LÄS MER
