  2. 2. Low-delay sensing and transmission in wireless sensor networks

    Author : Johannes Karlsson; Mikael Skoglund; Markus Flierl; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative communication; wireless sensor networks; low-delay transmission; joint source-channel coding; estimation; quantization; Telecommunication; Telekommunikation;

    Abstract : With the increasing popularity and relevance of ad-hoc wireless sensor networks, cooperative transmission is more relevant than ever. In this thesis, we consider methods for optimization of cooperative transmission schemes in wireless sensor networks. READ MORE

  3. 3. The influence of clouds on Earth's radiation budget in global climate models

    Author : Johannes Karlsson; Gunilla Svensson; Henning Rodhe; Bjorn Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Meteorology; Meteorologi; Oceanography; Oceanografi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Considering the high sensitivity of climate to changes in cloudiness, the way clouds might change in a perturbed climate is important for the total temperature response. In fact, the cloud feedback has been identified as the main uncertainty in future projections, as simulated by global climate models. READ MORE

  4. 4. Wireless video sensor network and its applications in digital zoo

    Author : Johannes Karlsson; Haibo Li; Jerry Eriksson; Oliver Wu Dapeng; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Wireless ad-hoc Networks; Digital Zoo; Video Compression; Real-Time Video Communication; Object Tracking; Sensor Fusion; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik; signalbehandling; Signal Processing;

    Abstract : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. READ MORE

  5. 5. GABA-, glycine- and glutamate-induced currents in rat medial preoptic neurons : functional interactions and modulation by capsaicin

    Author : Urban Karlsson; Staffan Johansson; Johannes Krupp; Bryndis Birnir; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic transmission; glutamate; GABA; glycine; TRPV1; Physiology; Fysiologi;

    Abstract : The medial preoptic nucleus (MPN) of the hypothalamus plays a major role in many functions involved in maintaining bodily homeostasis, such as thermoregulation and osmoregulation, as well as in the control of complex behaviours, e.g. sexual behaviour. READ MORE
