16. Exploring Cost Estimation Inaccuracy - Why do practitioners still fail to predict the actuals?
Sammanfattning : The purpose of this research is to further explore why practitioners’ ability to predict actual results is still not satisfactory. This problem was investigated from two perspectives. First, the practitioners view on causes of inaccurate cost estimates was explored in a quantitative multiple case study. LÄS MER
17. Estimation of the In-Cylinder Air/Fuel Ratio of an Internal Combustion Engine by the Use of Pressure Sensors
Sammanfattning : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. LÄS MER
18. Adaptive model-based battery management - Predicting energy and power capability
Sammanfattning : The battery is the limiting system for automotive electrication due to cost, size, and uncertain degradation. To be competitive the battery must therefore be used optimally. LÄS MER
19. Low-Cost Navigation Systems : A Study of Four Problems
Sammanfattning : Today the area of high-cost and high-performance navigation for vehicles is a well-developed field. The challenge now is to develop high-performance navigation systems using low-cost sensortechnology. LÄS MER
20. Contributions to Delay, Gain, and Offset Estimation
Sammanfattning : The demand for efficient and reliable high rate communication is ever increasing. In this thesis we study different challenges in such systems, and their possible solutions. LÄS MER
