  1. 1. Meteorological impact and transmission errors in outdoor wireless sensor networks

    Författare :Hjalmar Wennerström; Lars-Åke Nordén; Christian Rohner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Wireless sensor networks have been deployed outdoors ever since their inception. They have been used in areas such as precision farming, tracking wildlife, and monitoring glaciers. These diverse application areas all have different requirements and constraints, shaping the way in which the sensor network communicates. LÄS MER

  4. 3. Model Based Reconstruction of Ultrasonic Images

    Författare :Erik Wennerström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis is concerned with reconstruction methods for ultrasonic imaging, primarily applied to non-destructive material inspection. In ultrasonic inspection, a specimen is insonified with pulses of high frequency ultrasound, which enters the material and propagates through it. LÄS MER

  5. 4. A Node-Link Perspective on the Impact of Local Conditions in Sensor Networks

    Författare :Hjalmar Wennerström; Lars-Åke Nordén; Christian Rohner; Lars Wolf; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; opportunistic communication; meterlological impact; packet corruption; multi-contacts; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks are made up of small battery-powered sensing devices with wireless communication capabilities, enabling the network to monitor the environment in which it is deployed. Through their flexible and cable-free design these networks open up for new deployment scenarios that were previously not plausible such as during a natural disaster. LÄS MER
