2. 16. The Use of Laboratory Analyses in Sweden : Quality and Cost-Effectiveness in Test Utilization

   Author : Mirja Mindemark; Anders Larsson; Lars-Olof Hansson; Per Simonsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; continuing medical education; cost control; cost savings; physician practice patterns; diagnostic tests; clinical chemistry; primary health care; health care costs; laboratory management; test utilization; trends; cost-effectiveness; inflammatory bowel disease; irritable bowel syndrome; calprotectin; cost avoidance; Clinical chemistry; Klinisk kemi; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

   Abstract : Laboratory analyses, essential in screening, diagnosis, treatment, and monitoring of disease, are indispensable in health care, but appropriate utilization is intricate. The overall aim of this thesis was to study the use of laboratory tests in Sweden with the objective to evaluate and optimize test utilization. READ MORE

4. 17. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

   Author : Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

   Abstract : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

5. 18. Data-Rich Multivariable Control of Heavy-Duty Engines

   Author : Maria Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

   Abstract : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. READ MORE

6. 19. On LQG-Optimal Event-Based Sampling

   Author : Marcus Thelander Andrén; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Event-based control; LQG control; sampled-data control; Stochastic control; Event-based PID control; Event-based state estimation; stochastic triggering;

   Abstract : Event-based control is a promising concept for the design of resource-efficient feedback systems, where events such as sampling, actuation, and data transmissions are triggered reactively based on monitored control performance rather than a periodic timer. In this thesis, we investigate how sampling and communication events should be triggered to fully exploit the potential of event-based control based on the classic linear–quadratic–Gaussian (LQG) framework.

7. 20. Control Structures for Low-Emission Combustion in Multi-Cylinder Engines

   Author : Maria Henningsson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; fumigation; mid-ranging control; HCCI engine; engine control;

   Abstract : Traditionally, heavy-duty diesel engines have high efficiencies but also high emissions of NOx and soot particles. New engine concepts show the potential to retain diesel-like efficiencies while reducing emissions by forming a completely or partially homogeneous mixture of fuel and air prior to ignition through compression.
