  1. 1. Computer-aided optimization of complex processes in production systems and urban environments

    Författare :Mikael Yamanee-Nolin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; modeling; simulation; complex processes; process systems engineering; preparative chromatography; blue-green systems;

    Sammanfattning : Complex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. LÄS MER

  3. 2. 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.

  4. 3. Efficient Memory Utilization in Resource Constrained Real-Time Systems

    Författare :Kaj Hänninen; Mikael Nolin; Robert Davis; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stack sharing; Real-Time systems; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : This thesis presents design and run-time techniques for efficient memory utilization in embedded real-time systems. The proposed techniques give developers means to reduce the memory consumption in the systems. LÄS MER

  5. 4. Introducing a Memory Efficient Execution Model in a Tool-Suite for Real-Time Systems

    Författare :Kaj Hänninen; Mikael Nolin; Christer Norström; Jukka Mäki-Turja; Ola Redell; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Execution Models; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : This thesis shows how development of embedded real-time systems can be made more efficient by introduction of an memory efficient execution model in a commercial development suite. To identify the need of additional support for execution models in development tools, the thesis investigate by a series of interviews, the common requirements in development of industrial embedded real-time systems.

  7. 5. Engineering Strength Response-Time Analysis : A Timing Analysis Approach for the Development of Real-Time Systems

    Författare :Jukka Mäki-Turja; Mikael Nolin; Michael González Harbour; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Vid utvecklingen av datorsystem som är en del av en större produkt, som t.ex. styrsystemet i en bil, ett flygplan eller medicinsk utrustning, ställs det ofta mycket hårda krav på säkerhet och tillförlitlighet. LÄS MER
