11. Model-Based Cognitive Radio Strategies
Sammanfattning : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. LÄS MER
12. Model-based design of haptic devices
Sammanfattning : Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and validating compact and computationally efficient simulation models to be used for the design process.

13. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR
Sammanfattning : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

14. Nonlinear Model-based Control of Automotive Powertrains
Sammanfattning : In recent years the focus of powertrain control has shifted perspective from control of the individual powertrain components to control of the complete powertrain, so-called integrated powertrain control. The idea presented in this thesis is to view the powertrain as one single control object and to used the engine as a torque actuator to the rest of the driveline. LÄS MER
15. An Empirical Investigation of Using Models During Requirements Engineering in the Automotive Industry
Sammanfattning : Context: The automotive industry is undergoing a major transformation from a manufacturing industry towards an industry that relies heavily on software. As one of the main factors for project success, requirements engineering (RE) plays a major role in this transition. LÄS MER
