2. 1. Studies of flow duct acoustics with applications to turbocharged engines

   Author : Hans Rämmal; Hans Boden; Mats Åbom; Antonio Torregrosa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IC-engine; turbocharger; duct termination; flow duct; exhaust system; inlet system; acoustic source; one-port; two-port; source model; transmission loss; two-port matrix; reflection coefficient; source strength; multi-load method; Acoustics; Akustik;

   Abstract : A number of experimental and theoretical studies, performed in the field of technical flow duct acoustics are presented in this thesis. The acoustical methods treated are implemented on turbocharged IC-engines and engine gas exchange system components. A new method based on the well-known two-load technique has been developed.

4. 2. Vehicle-in-the-loop validation of autonomous cars

   Author : Angel Molina Acosta; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backward reachability; scenario-based testing; multi-agent systems; Model Predictive Control;

   Abstract : Validation of autonomous driving (AD) cars is a difficult task because of the complexity that results from the integration of multiple systems and the variety of operating conditions. To this end, testing with real vehicles is crucial to ensure a thorough validation of AD cars. READ MORE

5. 3. Automatic Reduction Procedures for Chemical Mechanisms in Reactive Systems

   Author : Terese Lövås; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mechanism Reduction; Combustion; Physics; Emissions; Fysik; Fysicumarkivet A:2002:Lövås;

   Abstract : To deal with complex physical and chemical processes in reactive systems, such as combustion processes, it is necessary to find methods that simplify modelling in such a way that it becomes both more comprehensible and practically useful. In the work reported here a method for automatically reducing chemical reaction mechanisms has been developed for use in computer simulations of various combustion systems. READ MORE

6. 4. A High-end Reconfigurable Computation Platform for Particle Physics Experiments

   Author : Ming Liu; Axel Jantsch; Zhonghai Lu; Wolfgang Kuehn; Lennart Lindh; KTH; []
   Keywords : reconfigurable computing; FPGA implementation; HW SW co-design; pattern recognition; particle physics;

   Abstract : Modern nuclear and particle physics experiments run at a very high reaction rate and are able to deliver a data rate of up to hundred GBytes/s.  This data rate is far beyond the storage and on-line analysis capability. Fortunately physicists have only interest in a very small proportion among the huge amounts of data. READ MORE

7. 5. Evolutionary optimisation of a morphological image processor for embedded systems

   Author : Andreas Magnusson; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded system; machine vision; morphological image processing; genetic algorithm; Energi och material;

   Abstract : The work presented in this thesis concerns the design, development and implementation of two digital components to be used, primarily, in autonomously operating embedded systems, such as mobile robots. The first component is an image coprocessor, for high-speed morphological image processing, and the second is a hardware-based genetic algorithm coprocessor, which provides evolutionary computation functionality for embedded applications.
