  3. 2. Data Management in Vehicle Control-Systems

    Författare :Dag Nyström; Christer Norström; Rob van Ommering; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : As the complexity of vehicle control-systems increases, the amount of information that these systems are intended to handle also increases. This thesis provides concepts relating to real-time database management systems to be used in such control-systems. LÄS MER

  4. 3. Systematic Design and Analysis of Customized Data Management for Real-Time Database Systems

    Författare :Simin Cai; Cristina Seceleanu; Barbara Gallina; Dag Nyström; Marieke Huisman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Modern real-time data-intensive systems generate large amounts of data that are processed using complex data-related computations such as data aggregation. In order to maintain logical data consistency and temporal correctness of the computations, one solution is to model the latter as transactions and manage them using a Real-Time Database Management System (RTDBMS).

  5. 4. Systematic Design of Data Management for Real-Time Data-Intensive Applications

    Författare :Simin Cai; Cristina Seceleanu; Dag Nyström; Barbara Gallina; Luís Almeida; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Modern real-time data-intensive systems generate large amounts of data that are processed using complex data-related computations such as data aggregation. In order to maintain the consistency of data, such computations must be both logically correct (producing correct and consistent results) and temporally correct (completing before specified deadlines).

  7. 5. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks

    Författare :Ewa Hansen; Mats Björkman; Mikael Nolin; Dag Nyström; Thiemo Voigt; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; routing; energy efficiency; asymmetric communicaiton; communication; power consumption; computer networks; trådlösa sensornät; trådlös; kommunikation; energikonsumtion; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : In this thesis centralized routing methods for wireless sensor networks have been studied. The aim has been to prolong network lifetime by reducing the energy consumed by sensor-node communication.Wireless sensor networks are rapidly becoming common in application areas where information from many sensors is to be collected and acted upon.
