1. 1. Real-Time Time Metrology Using Space Geodetic Methods

   Författare :Carsten Rieck; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VLBI; Time metrology; UTC; TAI; time link combination; carrier phase; time transfer; real-time filtering; GNSS;

   Sammanfattning : Two main objectives in time and frequency metrology are the realization of the SI unit of time, and the construction and dissemination of atomic time scales based on the SI second. This thesis is mainly concerned with the latter of the two and has investigated the characteristics of space geodetic time and frequency comparison methods. LÄS MER

3. 2. CPU Resource Management and Noise Filtering for PID Control

   Författare :Vanessa Romero Segovia; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; embedded systems; real-time systems; multimedia; multicore; measurement noise; filtering; trade-offs; robustness; performance; SDU; noise gain; PID control;

   Sammanfattning : The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. LÄS MER

4. 3. On sparse voxel DAGs and memory efficient compression of surface attributes for real-time scenarios

   Författare :Dan Dolonius; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; directed acyclic graph; surface properties; neural networks; voxel; compression; spherical gaussians; light field; octree; filtering; geometry;

   Sammanfattning : The general shape of a 3D object can expeditiously be represented as, e.g., triangles or voxels, while smaller-scale features usually are parameterized over the surface of the object. LÄS MER

5. 4. Adaptive Real-time Monitoring for Large-scale Networked Systems

   Författare :Alberto Gonzalez Prieto; Rolf Stadler; George Pavlou; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Large-scale networked systems, such as the Internet and server clusters, are omnipresent today. They increasingly deliver services that are critical to both businesses and the society at large, and therefore their continuous and correct operation must be guaranteed. LÄS MER

7. 5. Image Processing Architectures for Binary Morphology and Labeling

   Författare :Hugo Hedberg; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; labeling; binary image processing; morphology; Hardware architectures; real-time;

   Sammanfattning : Conventional surveillance systems are omnipresent and most are still based on analog techniques. Migrating to the digital domain grants access to the world of digital image processing enabling automation of such systems, which means extracting information from the image stream without human interaction.
