21. Approximation Techniques for Timing Analysis of Complex Real-Time Embedded Systems
Sammanfattning : To date, many industrial embedded systems are very large, flexible, and highly configurable software systems, containing millions of lines of code and consisting of hundreds of tasks, many with real-time constraints, being triggered in complex, nested patterns. Furthermore, the temporal dependencies between tasks in such systems are difficult to determine analytically, and they vary the execution time and response time of tasks greatly. LÄS MER
22. Dendritic and axonal ion channels supporting neuronal integration : From pyramidal neurons to peripheral nociceptors
Sammanfattning : The nervous system, including the brain, is a complex network with billions of complex neurons. Ion channels mediate the electrical signals that neurons use to integrate input and produce appropriate output, and could thus be thought of as key instruments in the neuronal orchestra. LÄS MER
23. Making Sampled Simulations Faster by Minimizing Warming Time
Sammanfattning : A computer system simulator is a fundamental tool for computer architects to try out brand new ideas or explore the system’s response to different configurations when executing different program codes. However, even simulating the CPU core in detail is time-consuming as the execution rate slows down by several orders of magnitude compared to native execution. LÄS MER
24. Development of an efficient solver for detailed kinetics in reactive flows
Sammanfattning : The use of chemical kinetic mechanisms in CAE tools for reactive flow simulations is of high importance for studying and predicting pollutant formation. However, usage of complex reaction schemes is accompanied by high computational cost in both 1D and 3-D CFD frameworks. LÄS MER
25. Image segmentation using snakes and stochastic watershed : with applications to microscopy images of biological tissue
Sammanfattning : The purpose of computerized image analysis is to extract meaningful information from digital images. To be able to find interesting regions or objects in the image, first, the image needs to be segmented. This thesis concentrates on two concepts that are used for image segmentation: the snake and the stochastic watershed. LÄS MER
