  1. 1. Energy Efficient Protocols for Active RFID

    Författare :Björn Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

    Sammanfattning : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. LÄS MER

  3. 2. Architecting Smart Home Environments for Healthcare : A Database-Centric Approach

    Författare :Wagner Ourique de Morais; Bertil Svensson; Nicholas Wickström; Diego López-de-Ipiña González-de-Artaza; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Smart environments; system architectures; active databases; in-database processing; ambient assisted living;

    Sammanfattning : The development of system architectures and applications for smart homes and ambient assisted living has been the main activity of a number of academic and industrial research projects around the world. Existing system architectures for smart environments usually employ different architectural styles in a multi-layer logical architecture to support the integration and interoperation of heterogeneous hardware and software technologies, which are subsequently used to provide two major functionalities: monitoring and assistance.

  4. 3. Active Database Management Systems for Monitoring and Control

    Författare :Martin Sköld; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Active Database Management Systems (ADBMSs) have been developed to support applications with detecting changes in databases. This includes support for specifying active rules that monitor changes to data and rules that perform some control tasks for the applications. LÄS MER

  5. 4. Developing Theoretical and Empirical Definitions of Safety Problems in Driving Suitable for Active Safety Function Evaluation

    Författare :Mikael Ljung Aust; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; avoidance; driver behaviour; pre-crash scenarios; crash causation; adaptation; motivation; conceptual framework; active safety functions;

    Sammanfattning : In passive safety, the requirement specifications used for evaluation of protective functions are both standardised and specified at a high level of detail regarding evaluation scenario definition, performance metrics and pass/fail criteria. For active safety, while several propositions for evaluation scenarios have been made, neither these, nor performance metrics and pass/fail criteria have yet reached a similar level of detail and standardisation.

  7. 5. Natural Products as Leads for Pharmaceutically Active Compounds

    Författare :Pia Kahnberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scaffold hopping; Catalyst; anxiety; benzodiazepine site; GABAA receptor; pharmacophore model; flavones; SAR; antifungal activity; Complex I; pterulone; Organic chemistry; Organisk kemi; Biochemical technology; Biokemisk teknik;

    Sammanfattning : In the search for new pharmaceutically active compounds, it is recognized that Nature produces structurally different compounds in a great variety. By having the compounds or extracts tested in defined systems, new drugs or more often leads (a compound that has an interesting but moderate activity) can be found. LÄS MER
