2. 6. Asynchronous First-Order Algorithms for Large-Scale Optimization : Analysis and Implementation

   Author : Arda Aytekin; Mikael Johansson; Lin Xiao; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex; optimization; asynchronous; algorithms; parallel; distributed; large-scale; big data; software; serverless; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. READ MORE

4. 7. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

   Author : Rasmus Bokrantz; Anders Forsgren; Karl-Heinz Küfer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

   Abstract : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. READ MORE

5. 8. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

   Author : Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. READ MORE

6. 9. Distributed Optimization of P2P Media Delivery Overlays

   Author : Amir H. Payberah; Seif Haridi; Alberto Montresor; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; P2P overlay networks; P2P live streaming; Distributed optimization; Electronics; Elektronik; Computer and systems science; Data- och systemvetenskap;

   Abstract : Media streaming over the Internet is becoming increasingly popular. Currently, most media is delivered using global content-delivery networks, providing a scalable and robust client-server model. However, content delivery infrastructures are expensive. READ MORE

7. 10. Quality-Driven Synthesis and Optimization of Embedded Control Systems

   Author : Soheil Samii; Petru Eles; Zebo Peng; Samarjit Chakraborty; Linköpings universitet; []
