  1. 1. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :María Xuan Celaya Granados; [2023]
    Nyckelord :;

    Sammanfattning : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. LÄS MER

  3. 2. Identifying Bluetooth Low Energy Devices via Physical-Layer Hardware Impairments

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : It is desirable to be able to distinguish between Bluetooth Low Energy (BLE) devices purely based on individual hardware imperfections because such imperfections are often prohibitly expensive to imitate. Other works have been done on this topic in the past, which utilized signal transients requiring a multi-GHz sampling rate recorded with costly special equipment to be satisfactorily captured.

  4. 3. VHF/UHF Uplink Solutions for Remote Wireless Sensor Networks

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

    Författare :Alp Sayin; [2013]
    Nyckelord :;

    Sammanfattning : The purpose of this thesis was to compare alternative wireless links for transfer of data from sink motes of remote wireless sensor networks to a central repository. A few different protocol stacks to be implemented in the WSN (Wireless Sensor Network) uplink gateway and along with them a few implementation environments based on open source software and low-power hardware were discussed.

  5. 4. A TinyOS Testbed for CC2420 Transceivers

    Master-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Författare :Muhammad Asif Jamal; [2013]
    Nyckelord :TinyOS; Motes; WSN; RSS; testbed; nesC; MICAz; MIB520; Handshaking; Frame length byte;

    Sammanfattning : Wireless Sensor Networks (WSNs) have gained significant consideration these days, as opposed to wired sensor networks, by introducing multi-functional wireless nodes, which are smaller in size. The main advan-tage is that its wireless, so it costs less to install, maintain and reconfig-ure. These sensor nodes are used in various application areas. LÄS MER

  7. 5. Energismart bevattningssystem

    M1-uppsats, KTH/Data- och elektroteknik

    Författare :Daniel Söderholm; Markus Fröberg; [2013]
    Nyckelord :;

    Sammanfattning : Energismarta lösningar är väldigt aktuellt och alla möjligheter till att spara energi anses absolut nödvändiga för att värna om naturen. Energi kan sparas på bevattningsanläggningar genom att inte vattna om nederbörd är annalkande. LÄS MER
