1. 16. Distributed Optimization with Nonconvexities and Limited Communication

   Författare :Sindri Magnússon; Carlo Fischione; Juan Miguel Morales González; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Nonconvex Optimization; Wireless Sensor Networks; Cyberphysical Systems.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In economical and sustainable operation of cyber-physical systems, a number of entities need to often cooperate over a communication network to solve optimization problems. A challenging aspect in the design of robust distributed solution algorithms to these optimization problems is that as technology advances and the networks grow larger, the communication bandwidth used to coordinate the solution is limited.

3. 17. Fast local optimization in decision analytic software

   Författare :Xiasong Ding; Love Ekenberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bilinear programming; decision analysis; optimization; linear progamming; decision support systems; iterative method; Computer science; Datavetenskap;

   Sammanfattning : In decision analysis, significant recognition has been given to the fact that requiring numerically precise information seems unrealistic for real-life decision situations, Despite the emergence of many modern apporaches, which attempt to handle imprecise estimates, concentration has focused more on representation and less on evaluation. Methods such as the DELTA method  challenged this issue by its evaluation framework that can accommodate both precision an imprecision, and thus pushes forward the disign of advanced dicision analysis systems.

4. 18. Optimization and Control in Dynamical Network Systems

   Författare :Håkan Terelius; Karl Henrik Johansson; Alexandre Proutiere; Giacomo Como; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Networks; Transportation; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Dynamical network systems are complex interconnected systems useful to describe many real world problems. The advances in information technology has led the current trend towards connecting more and more systems, creating "intelligent" systems, where the intelligence originates in the scale and complexity of the network.

5. 19. Automated Driving Maneuvers - Trajectory Planning via Convex Optimization in the Model Predictive Control Framework

   Författare :Julia Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Model Predictive Control; Trajectory planning; Lane Change; Automated Driving; Autonomous Driving; Advanced Driver Assistance Systems;

   Sammanfattning : Highly automated vehicles have the potential to provide a variety of benefits e.g., decreasing traffic injuries and fatalities while offering people the freedom to choose how to spend their time in their vehicle without jeopardizing the safety of themselves or other traffic participants.

7. 20. Rank Reduction with Convex Constraints

   Författare :Christian Grussler; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-rank approximation; model reduction; non-convex optimization; Douglas-Rachford; matrix completion; overlapping norm; k-support norm; atomic norm;

   Sammanfattning : This thesis addresses problems which require low-rank solutions under convex constraints. In particular, the focus lies on model reduction of positive systems, as well as finite dimensional optimization problems that are convex, apart from a low-rank constraint. LÄS MER
