2. 21. Reactive Shared Objects for Interprocess Synchronization

   Author : Phuong Ha; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-blocking; distributed data structures; online algorithms; trees; reactive synchronization; practical; lock-free;

   Abstract : In parallel processing environments such as multiprocessor systems, processes are synchronized using concurrent objects, which allow many concurrent processes to access them at the same time. The performance of these concurrent objects heavily relies on the load conditions of the surrounding environment (e.g. READ MORE

4. 22. Machine Learning for Wireless Link Adaptation : Supervised and Reinforcement Learning Theory and Algorithms

   Author : Vidit Saxena; Joakim Jaldén; Mats Bengtsson; Hugo Tullberg; Jakob Hoydis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Communications; Reinforcement Learning; Multi-Armed Bandits; Thompson Sampling; Convex Optimization; Deep Learning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Wireless data communication is a complex phenomenon. Wireless links encounter random, time-varying, channel effects that are challenging to predict and compensate. Hence, to optimally utilize the channel, wireless links adapt the data transmission parameters in real time. READ MORE

5. 23. Modeling and constructing unstructured overlay networks: Algorithms, techniques and the Smart Grid case

   Author : Georgios Georgiadis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; matching; smart grid; online computation; scheduling; unstructured overlays; random walks; natural computing; resistor networks; clustering;

   Abstract : Throughout its lifetime, the Internet was always associated with overlay networks; from the WorldWideWeb and peer-to-peer networks to blogs and social networking solutions, overlays built on the Internet infrastructure gave it additional value and made it more engaging to everyday users. Today, rising overlay networks such as the Smart Grid as well as a multitude of sensor, mobile andwireless networks herald a new era of unprecedented connectivity and networking. READ MORE

6. 24. Efficient Online Learning under Bandit Feedback

   Author : Stefan Magureanu; Alexandre Proutiere; Odalric-Ambrym Maillard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-armed bandits; reinforcement learning; learning to rank; Electrical Engineering; Elektro- och systemteknik;

   Abstract : In this thesis we address the multi-armed bandit (MAB) problem with stochastic rewards and correlated arms. Particularly, we investigate the case when the expected rewards are a Lipschitz function of the arm and extend these results to bandits with arbitrary structure that is known to the decision maker.

7. 25. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning

   Author : Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; George Anders; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The importance of electricity in everyday life and demands to improve the reliability of distribution systems force utilities to operate and plan their networks in a more secure and economical manner. With higher demands on reliability from both customers and regulators, a big pressure has been put on the security of electricity supply which is considered as a fundamental requirement for modern societies.
