1. Stability and inactivation mechanisms of two transaminases
Sammanfattning : In the past decades, more and more enzymes are employed as biocatalysts in industrial processes because of their advantages, such as high efficiency, substrate selectivity and stereoselectivity. Among them, amine transaminases (ATAs) are pyridoxal 5’-phosphate (PLP) dependent enzymes. LÄS MER
2. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation
Sammanfattning : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. LÄS MER
3. The Effect of Different Perturbations on the Stability Analysis of Light Water Reactors
Sammanfattning : Neutron noise analysis techniques are studied and developed, with primary useof determining the stability of Boiling Water Reactors (BWRs). In particular, the role ofa specific perturbation prevailing in Light Water Reactors, the propagating densityperturbation, in the stability of BWRs and on the noise field of LWRs in general, isinvestigated by considering three topics.

4. Data-driven methods for real-time voltage stability assessment
Sammanfattning : Voltage instability is a phenomenon that limits the operation and the transmission capacity of a power system. An operation state close to the security limits enables a cost-effective utilization of the system but it could also make the system more vulnerable to disturbances. LÄS MER
5. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis
Sammanfattning : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. LÄS MER
