1. 16. Offshore renewable energy systems : Quantification of extreme loads using computational methods

   Författare :Eirini Katsidoniotaki; Malin Göteman; Alison Raby; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore systems; wave energy; CFD; extreme events; machine learning; Bayesian experimental design; active learning; surrogate modeling;

   Sammanfattning : This Ph.D. thesis investigates the dynamic response of offshore energy systems in extreme waves. The use of offshore energy technologies, such as wave energy systems and offshore wind turbines, is crucial for transitioning to clean energy and mitigating the effects of climate change. LÄS MER

3. 17. On Efficient Transmission Balancing Operation : Capturing the Normal State Frequency and Active Power Dynamics

   Författare :Martin Nilsson; Lennart Söder; Julia Matevosyan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Power Dynamics; Frequency Control; Normal State; Power System Balancing; Transmission System Operator; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In an electric power system, there will always be an electric balance. Nevertheless, System Operators (SOs) often uses the term imbalance. Here, the term imbalance refers to the difference between trades and real-time measurements. LÄS MER

4. 18. BRIDGING THE INFORMATION GAP : Supporting Evidence-Based Medicine and Shared Decision-Making through Information Systems

   Författare :Hanife Rexhepi; Peter Bath; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Systems; Informationssystem IS ;

   Sammanfattning : Practicing evidence-based medicine (EBM) and shared decision-making (SDM)along the patient process is important in today's healthcare environment, as thesemodels of care offer a way to improve quality and safety of care, patient satisfaction,and reduce costs. EBM is the conscientious and judicious use of current best medicalevidence in conjunction with clinical expertise. LÄS MER

5. 19. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects

   Författare :Babak Rasolzadeh; Jan-Olof Eklundh; Ales Leonardis; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

   Sammanfattning : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. LÄS MER

7. 20. Analyzing real-world data to promote development of active safety systems that reduce car-to-vulnerable road user accidents

   Författare :Azra Habibovic; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident prevention; Naturalistic observation; Causation analysis; Active safety system; Vulnerable road user VRU ; Driver behavior; Functional requirements; Statistical analysis; VRU behavior;

   Sammanfattning : The overall objective of the thesis is to explore various types of real-world road traffic data and to assess the extent to which they can inform the design of active safety systems that aim to prevent car-to-vulnerable road user (VRU) accidents. A combined analysis of in-depth and police reported accident data provided information on driver behavior and contextual variables, which is valuable for the development of active safety systems.
