3. 27. On Optimization-Based Falsification of Cyber-Physical Systems

   Författare :Zahra Ramezani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian Optimization; Model-Based Testing; Optimization-Based Falsification; Cyber-Physical Systems; Quantitative Semantics; Input Generators;

   Sammanfattning : In what is commonly referred to as cyber-physical systems (CPSs), computational and physical resources are closely interconnected. An example is the closed-loop behavior of perception, planning, and control algorithms, executing on a computer and interacting with a physical environment. LÄS MER

4. 28. Performance Analysis of Positive Systems and Optimization Algorithms with Time-delays

   Författare :Hamid Reza Feyzmahdavian; Mikael Johansson; Peter Richtarik; KTH; []
   Nyckelord :Optimization; Delay; Positive system; Asynchronous; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Time-delay dynamical systems are used to model many real-world engineering systems, where the future evolution of a system depends not only on current states but also on the history of states. For this reason, the study of stability and control of time-delay systems is of theoretical and practical importance. LÄS MER

5. 29. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

   Författare :Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

   Sammanfattning : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.

7. 30. Optimization-Based Models for Measuring and Hedging Risk in Fixed Income Markets

   Författare :Johan Hagenbjörk; Jörgen Blomvall; Ou Tang; Giorgio Consigli; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finance; Fixed income; Interest rate risk; Credit risk; Risk management; Optimization; Mathematics;

   Sammanfattning : The global fixed income market is an enormous financial market whose value by far exceeds that of the public stock markets. The interbank market consists of interest rate derivatives, whose primary purpose is to manage interest rate risk. LÄS MER
