1. Bortom kontroll? : Den svenska kemikalieövervakningens logik
Sammanfattning : Kemikalier utgör en grundläggande beståndsdel av det senindustriella samhället, och en omfattande produktion av kemikalier brukar allmänt anses som en nödvändig förutsättning för teknisk utveckling och ekonomisk tillväxt. I Sverige ledde miljölarmen om DDT, PCB och kvicksilver på 1960- och 1970-talet till inrättandet av ett system för kemikaliekontroll som brukar framhållas som ett av världens främsta. LÄS MER
2. Enabling and Coercive Control : Coexistence in the Case of Banking
Sammanfattning : This thesis focuses on subjects of control and attitudinal outcomes of formalized control in organizations. Previous research have concluded contradicting results of whether formalized control is positive or negative for the employees and propose that not only degree of formalization, but also type of formalization, can explain attitudinal outcomes.

3. Event-Based Control and Estimation with Stochastic Disturbances
Sammanfattning : This thesis deals with event-based control and estimation strategies, motivated by certain bottlenecks in the control loop. Two kinds of implementation constraints are considered: closing one or several control loops over a data network, and sensors that report measurements only as intervals (e.g. with quantization).

4. Control of EGR and VGT for emission control and pumping work minimization in diesel engines
Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER
5. The stochastic nature of intracellular control circuits
Sammanfattning : Chemical reactions are probabilistic by nature, causing random fluctuations inconcentrations to emerge spontaneously. In conventional (macroscopic) kinetics this internal noise is ignored under the assumption that average copy numbers are so high that fluctuations are negligible in comparison. LÄS MER
