  2. 21. Optimal and Adaptive Subband Beamforming

    Author : Nedelko Grbic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Optimal; Adaptive; Speech Enhancement;

    Abstract : The increased use of personal communication devices, personal computers and wireless cellular telephones enables the development of new inter-personal communication systems. The merge between computers and telephony technologies brings up the demand for convenient hands-free communications. READ MORE

  4. 22. Performance and Implementation Complexity in Multiprocessor Operating System Kernels

    Author : Simon Kågström; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Operativsystem; multiprocessorer; implementationskomplexitet;

    Abstract : The increasing use of multiprocessor computers require operating system adaptations to take advantage of the computing power. However, porting an operating system kernel to run on a multiprocessor can be very difficult because of a large code base, concurrency issues when dealing with multiple threads of execution, and limited tool support for development.

  5. 23. On Observation of and Interaction in Open Distributed Systems

    Author : Jens-Olof Lindh; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherence; interaction; temporal interval; relativity; uncertainty;

    Abstract : The thesis presents the results of research in computer science, as applied within a series of industrial projects. All of these projects have been part of an iterative and adaptive development process, from which we can draw conclusions in three different aspects. READ MORE

  6. 24. On the Quality of Computer Network Measurements

    Author : Patrik Arlos; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Network Measurements; Network Measurement Accuracy; Timestamp Accuracy; Quality of Measurements; Traffic Generation; Analysis; Sampling;

    Abstract : Due to the complex diversity of contemporary Internet-services, computer network measurements have gained considerable interest during recent years. Since they supply network research, development and operations with data important for network traffic modelling, performance and trend analysis, etc. READ MORE

  7. 25. Railway traffic disturbance management

    Author : Johanna Törnquist; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Railway traffic; Transportation; Re-scheduling; Disturbance management; Decision support systems;

    Abstract : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. READ MORE
