36. Risk stratification in cardiac surgery: Algorithms and applications
Sammanfattning : The aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural networks (ANNs) to select and rank the most important risk factors for operative mortality in open-heart surgery. Preoperative evaluation of the surgical risk is an important component in cardiac surgery. LÄS MER
37. Foresight and Feedback: Monitoring and assessing the environmental implications of emerging technologies
Sammanfattning : The magnitude of the change required to approach sustainability indicates an effort that will have to be sustained over decades, during which vast new technology systems will have to be developed and deployed. Yet technological development is a double edged sword, and these efforts will inevitably incur unintended consequences. LÄS MER
38. Design of Assured and Efficient Safety-critical Systems
Sammanfattning : Safety-critical systems need to be analyzed rigorously to remove software/specifications errors, that is, their requirements specifications should be unambiguous, comprehensible and consistent, and the software design should conform to the specifications, hence avoiding undesirable system failures. Currently, there is a lack of effective and scalable methods to specify and analyze requirements, and formally analyze the behavioral models of embedded systems. LÄS MER
39. Preservation of Extra-Functional Properties in Embedded Systems Development
Sammanfattning : The interaction of embedded systems with their environments and their resource limitations make it important to take into account properties such as timing, security, and resource consumption in designing such systems. These so-called Extra-Functional Properties (EFPs) capture and describe the quality and characteristics of a system, and they need to be taken into account from early phases of development and throughout the system's lifecycle.

40. Model-driven Analysis and Verification of Automotive Embedded Systems
Sammanfattning : Modern vehicles are equipped with electrical and electronic systems that implement highly complex functions, such as anti-lock braking, cruise control, etc. To realize and integrate such complex embedded systems, the automotive development process requires an updated methodology that takes into consideration the system’s intricate features and examines both their functional and extra-functional requirements.
