1. Flexible Embedded Control Systems : Design and Implementation
Sammanfattning : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. LÄS MER
2. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors
Sammanfattning : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. LÄS MER
3. Multistage gearboxes : vibration based quality control
Sammanfattning : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. LÄS MER
4. Models for Estimation of Software Faults and Failures in Inspection and Test
Sammanfattning : In software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. LÄS MER
5. On Falsification of Large-Scale Cyber-Physical Systems
Sammanfattning : In the development of modern Cyber-Physical Systems, Model-Based Testing of the closed-loop system is an approach for finding potential faults and increasing quality of developed products. Testing is done on many different abstraction levels, and for large-scale industrial systems, there are several challenges. LÄS MER
