  1. 1. Data Logging for Controller Area Network of Autonomous Vehicles : An Investigation of a CAN-Ethernet Gateway

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Daniel Grönås; Fredrik Mazur; [2022]
    Nyckelord :CAN; CAN FD; Ethernet; Gateway; Network; CAN-ETH; CAN-Ethernet; Data Logging; Autonomous Vehicle; CAN; CAN FD; Ethernet; Nätsluss; Nätverk; CAN-ETH; CAN-Ethernet; Dataloggning; Autonoma Fordon;

    Sammanfattning : With the development of autonomous vehicles, more and more technology is introduced into the automotive industry. Ethernet has found its way into the vehicle network, and it is forced to coexist with the well-established CAN bus. LÄS MER

  3. 2. Geodesic Lens Antenna for sub-THz Imaging

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joan Mitjans i Blasco; [2021]
    Nyckelord :;

    Sammanfattning : The Millimiter Wave (mmW) frequency band, characterized by a high atmospheric attenuation and wide available bandwidth has become of big interest for high accuracy radar imaging applications. The continuous development of the Monolithic Microwave Integrated Circuit (MMIC) technology yields to the appearance of different commercial-off-the-shelf (COTS) radar transceivers at that frequency band, where the antennas are fully integrated into the chip.

  4. 3. Synchronization of Distributed Units without Access to GPS

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Erik Carlsson; [2018]
    Nyckelord :Timing algorithm; Communications system; QPSK; FPGA; VHDL;

    Sammanfattning : Time synchronization between systems having no external reference can be an issue in small wireless node-based systems. In this thesis a transceiver is designed and implemented in two separate systems. Then the timing algorithm of "TwoWay Time Transfer" is then chosen to correct any timing error between the two free running clocks of the systems. LÄS MER

  5. 4. Exploiting Wireless Sensors : A gateway for 868 MHz sensors

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Albert López Garcia; Francisco Javier Sánchez Galisteo; [2012]
    Nyckelord :wireless sensor gateway; microcontoller; power over ethernet;

    Sammanfattning : The great interest in monitoring everything around us has increased the number of sensors that we utilize in our daily lives. Furthermore, the evolution of wireless technologies has facilitated their ubiquity. Moreover, is in locations such as homes and offices where exploitation of the data from these sensors has been more important. LÄS MER

  7. 5. A Performance Evaluation of RPL in Contiki

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Hazrat Ali; [2012]
    Nyckelord :RPL; Routing metrics; Cooja; Objective Function; Evaluation; Low Power and Lossy Networkk;

    Sammanfattning : A Wireless Sensor Network is formed of several small devices encompassing the capability of sensing a physical characteristic and sending it hop by hop to a central node via low power and short range transceivers. The Sensor network lifetime strongly depends on the routing protocol in use. LÄS MER
