21. Managing Software Quality through Empirical Analysis of Fault Detection
Sammanfattning : Software often constitutes a large share of today's products. To deliver a product with the level of software quality expected by the customer, software development organizations need to manage quality achievement and assessment. In practice, quality is often referred to as the lack of bugs. LÄS MER
22. A Fault Detection Framework Using Recurrent Neural Networks for Condition Monitoring of Wind Turbines
Sammanfattning : The global energy system is experiencing a transition to a sustainable system with ambitious targets for increased use of renewable energy. One key trend for this transition has been the large introduction of wind power and integration into the electricity grid. LÄS MER
23. Power System Oscillations - Detection, Estimation and Control
Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER
24. Multiple-Bit Errors in Computer Systems
Sammanfattning : This thesis discusses the types of transient faults caused by heavy-ion or a-particle radiation that manifest as multiple-bit errors and how information redundancy techniques can achieve fault tolerance with respect to some classes of multiple-bit errors. The first part of the thesis considers the fault modelling problem, beginning with the problem of how single event upsets (SEUs) originating from faults in register cells in microprocessors manifest as primary errors.

25. Fault detection in district heating substations
Sammanfattning : This thesis gives a summary of different faults that occur in district heating substations and suggests ways of detecting them. The aim of the research has been to achieve fault detection using only the heat meter and the sensors connected to it, namely two temperature sensors and one flow meter. LÄS MER
