  1. 1. 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.

  3. 2. A case-based multi-modal clinical system for stress management

    Författare :Mobyen Uddin Ahmed; Peter Funk; Ning Xiong; Bo von Schéele; Nosrat Shahsavar; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress management; diagnosis and treatment; multi-purpose and multi-modal; Case-based reasoning; textual information retrieval; rule-based reasoning; and fuzzy logic; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : A difficult issue in stress management is to use biomedical sensor signal in the diagnosis and treatment of stress. Clinicians often make their diagnosis and decision based on manual inspection of physiological signals such as, ECG, heart rate, finger temperature etc. LÄS MER

  4. 3. New Strategies for Ensuring Time and Value Correctness in Dependable Real-Time Systems

    Författare :Hüseyin Aysan; Sasikumar Punnekkat; Iain Bate; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : Dependable real-time embedded systems are typically composed of a number of heterogeneous computing nodes, heterogeneous networks that connect them and tasks with multiple criticality levels allocated to the nodes. The heterogeneous nature of the hardware, results in a varying vulnerability to different types of hardware failures. LÄS MER

  5. 4. Formal Approaches to Service-oriented Design : From Behavioral Modeling to Service Analysis

    Författare :Aida Čaušević; Paul Pettersson; Jonathan P. Bowen; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; service-oriented software engineering; formal modeling; service-oriented systems; resources; analysis; behavior; correctness check; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : Service-oriented systems (SOS) have recently emerged as context-independent component-based systems. In contrast to components, services can be created, invoked, composed and destroyed at run-time. Services are assumed to be platform independent and available for use within heterogeneous applications. LÄS MER

  7. 5. Information Centric Development of Component-Based Embedded Real-Time Systems

    Författare :Andreas Hjertström; Mikael Sjödin; Dag Nyström; Luis Almeida; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Database; Real-Time; RTDBMS; Component; CBSE; Database proxy; Data entity; data management; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : This thesis presents new techniques for data management of run-time data objectsin component-based embedded real-time systems. These techniques enabledata to be modeled, analyzed and structured to achieve data managementduring development, maintenance and execution. LÄS MER
