   Sammanfattning : .... LÄS MER

3. 2. Protocols with Heterogeneous Real-Time Services for High-Performance Embedded Networks

   Författare :Carl Bergenhem; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical; Ring; Pipeline; Distributed; Parallel-Processing; Real-time; SAN; System Area Network; Heterogeneous; Service;

   Sammanfattning : Network protocols for applications that demand high performance and heterogeneous real-time services are presented. These protocols control the medium access to the network and offer additional features to the user, both different user services for traffic and services for parallel and distributed real-time processing.

4. 3. Virtual Full Replication for Scalable Distributed Real-Time Databases

   Författare :Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik;

   Sammanfattning : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

5. 4. Fibre-Optic AWG Networks Supporting Real-Time Communication in High-Performance Embedded Systems

   Författare :Kristina Kunert; Magnus Jonsson; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time communication; medium access control MAC protocol; traffic dependency analysis; network architecture; Arrayed Waveguide Grating AWG ; optical communication; real-time analysis; optical network; Computer engineering;

   Sammanfattning : High-performance embedded systems communicating heterogeneous traffic with high bandwidth and strict timing requirements are in need of more efficient communication solutions. This thesis proposes two multi-wavelength passive optical networks able to meet these demands. LÄS MER

7. 5. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

   Författare :Ola Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

   Sammanfattning : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.
