1. On Gas Dynamics of Exhaust Valves
Abstract : With increasing effects of global warming, efforts are made to make transportationin general more fuel efficient. When it comes to internal combustion engines,the most common way to improve fuel efficiency is through ‘downsizing’. Downsizingmeans that a smaller engine (with lower losses and less weight) performsthe task of a larger engine. READ MORE

2. Signs of inflammation in different types of heart valve disease : The VOCIN study
Abstract : Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. READ MORE

3. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine
Abstract : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. READ MORE

4. Experimental Methods in Valve Characteristic Assessment
Abstract : This thesis deals with experimental methods for assessing performance and characteristics of fluid power valves. Mobile applications are traditionally manually operated open-loop systems. However, there is an increasing number of applications where it is interesting to use feedback controls in an outer loop. READ MORE

5. Experimental validation of dynamic component models
Abstract : Proper coil function is an important issue regardingair-handling devices. Thus, proper modeling is important. Thepresent work deals with simulation of heating coil subsystems,especially validation on component level. READ MORE
