  1. 1. Model of dynamic behavior for frame mounted truck components

    Master-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Erik Bäckström; [2019]
    Nyckelord :;

    Sammanfattning : In the truck industry, it is crustal to test components against fatigue to make sure that the trucks stand up to the high demands on durability. Today’s testing methods have some disadvantages; it is quite a time-consuming process, but more important, similar tested components cannot easily be compared due to the load spread the components are subjected to.

  3. 2. New Generation 4-Channel GNSS Receiver : Design, Production, and Testing

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Guillem Antoja Lleonart; [2018]
    Nyckelord :gnss; gps; galileo; glonass; beidou; constellation; receiver; new generation; 4-channel; design; pcb; shield; front end; nt1065; biastee; bias t; bias tee; sma; saw filter; fpga; microzed; microheader; digital; analog; lvds; single end; agc; selector;

    Sammanfattning : Due to the current research needs and the lack of commercial multi-channel, multi-constellation GNSS receivers, a two-board solution has been developed so it can be mated with and take advantage of the processing power of the FPGA board branded as MicroZed. In order to achieve the proposed goals, an initial phase for assessing and updating the older design, building, and testing of SiGe modules (including both the electronics and casings) has been carried out.

  4. 3. Mapping Images - When words don't work

    Master-uppsats, Kungl. Konsthögskolan

    Författare :Malou da Cunha Bang; [2016]
    Nyckelord :stories juxtaposing inspiration narrative images mapping;

    Sammanfattning : Mapping images – when words don’t work. My master essay is a walking contradiction. It is an explanation of how a non-wordly thought process emerged – but explained in words. LÄS MER

  5. 4. Potential Capacity for Wi-Fi system In TV White Space

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Yanpeng Yang; [2012]
    Nyckelord :;

    Sammanfattning : In recent years, the demand of bandwidth has increased rapidly due to the growth of new technologies in wireless communication systems along with the rise of traffic flow. This has made the radio spectrum in a short supply. LÄS MER

  7. 5. Adaptive Sub band GSC Beam forming using Linear Microphone-Array for Noise Reduction/Speech Enhancement.

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Mamun Ahmed; [2012]
    Nyckelord :Generalized Side lobe Canceller GSC ; Blocking matrix; Microphone array; Sub band; SNR. ;

    Sammanfattning : This project presents the description, design and the implementation of a 4-channel microphone array that is an adaptive sub-band generalized side lobe canceller (GSC) beam former uses for video conferencing, hands-free telephony etc, in a noisy environment for speech enhancement as well as noise suppression. The side lobe canceller evaluated with both Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) adaptation. LÄS MER
