  1. 11. Efficient and Flexible Embedded Systems and Datapath Components

    Författare :Magnus Själander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flexible; Twin-Precision; Scheduling; Embedded; Multiplier; Multi-Core;

    Sammanfattning : The comfort of our daily lives has come to rely on a vast number of embedded systems, such as mobile phones, anti-spin systems for cars, and high-definition video. To improve the end-user experience at often stringent require-ments, in terms of high performance, low power dissipation, and low cost, makes these systems complex and nontrivial to design. LÄS MER

  5. 14. Modelling and design of high-power HBV multipliers

    Författare :Mattias Ingvarson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal limitations; semiconductor; millimetre and sub-millimetre wave power source; varactor diode; frequency multiplier; heterostructure barrier varactor;

    Sammanfattning : This thesis deals with symmetric varactor frequency multipliers for millimetre and sub-millimetre wave applications. Much of the material presented is general and applicable to any type of (symmetric) varactor, but the focus is on the heterostructure barrier varactor (HBV). The basic function and principles of HBVs are explained. LÄS MER

  7. 15. Some new Fourier multiplier results of Lizorkin and Hörmander types

    Författare :Lyazzat Sarybekova; Michael L. Goldman; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fourier multipliers; Lizorkin theorem; Hörmander theorem; regular system; Mathematics; Matematik; Mathematics; Matematik;

    Sammanfattning : This PhD Thesis is devoted to the study of Fourier series and Fourier transform multipliers and it contains four papers (papers A - D) together with an introduction, which put these papers into a general frame. This extensive introduction can also be seen as an independent description of this important area including the historical development and the most important results. LÄS MER
