  1. 11. III-V MOSFETs for High-Frequency and Digital Applications

    Författare :Cezar Zota; Nanoelektronik; []
    Nyckelord :III-V; MOSFET; Transistor;

    Sammanfattning : III-V compound semiconductors are used in, among many other things, high-frequency electronics. They are also considered as a replacement for silicon in CMOS technology. Yet, a III-V transistor outperforming state-of-the-art silicon devices in VLSI-relevant metrics has not yet decisively been demonstrated. LÄS MER

  3. 12. Heterostructure Barrier Varactor Diodes for Frequency Multiplier Applications

    Författare :Jan Stake; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor; millimetre- and submillimetre wave power source; Heterostructure Barrier Varactor HBV ; frequency multiplier; varactor diode;

    Sammanfattning : This thesis deals with fabrication, characterisation and modelling of the Heterostructure Barrier Varactor (HBV) diode and its use in frequency multiplier circuits. Different aspects of material structures and frequency multipliers are described. LÄS MER

  4. 13. Compile-time Safety and Runtime Performance in Programming Frameworks for Distributed Systems

    Författare :Lars Kroll; Seif Haridi; Jim Dowling; Peter Van Roy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; distributed computing; programming systems; programming languages; computer science; domain specific languages; message-passing; actor model; component model; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Distributed Systems, that is systems that must tolerate partial failures while exploiting parallelism, are a fundamental part of the software landscape today. Yet, their development and design still pose many challenges to developers when it comes to reliability and performance, and these challenges often have a negative impact on developer productivity.

  7. 15. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations

    Författare :Viktor Larsson; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Geometric Vision; minimal solvers; Convex relaxation; Pose estimation;

    Sammanfattning : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. LÄS MER
