2. 1. Small-Scale Decentralized Energy Systems : optimization and performance analysis

   Author : Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

   Abstract : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. READ MORE

4. 2. On Distributed Optimization in Networked Systems

   Author : Björn Johansson; Mikael Johansson; Asuman Ozdaglar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; resource allocation; networked systems; peer-to-peer; distributed optimization; Telecommunication; Telekommunikation; Automatic control; Reglerteknik;

   Abstract : Numerous control and decision problems in networked systems can be posed as optimization problems. Examples include the framework of network utility maximization for resource allocation in communication networks, multi-agent coordination in robotics, and collaborative estimation in wireless sensor networks (WSNs).

5. 3. Cardiac Resynchronization Therapy Optimization : Comparison and Evaluation of Non-invasive Methods

   Author : Elena Sciaraffia; Carina Blomström Lundqvist; Giuseppe Boriani; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac resynchronization therapy; device optimization; left ventricular contractility; Cardiology; Kardiologi;

   Abstract : The general purpose of this thesis was to investigate new cardiac resynchronization therapy (CRT) optimization techniques and to assess their reliability when compared to invasive measurements of left ventricular contractility (LV dP/dtmax).We first assessed whether cardiac output (CO) measured by trans-thoracic impedance cardiography could correctly identify the optimal interventricular (VV) pacing interval while using invasive measurements of LV dP/dtmax as reference.

6. 4. Multi-Criteria Optimization of System Integration Testing

   Author : Sahar Tahvili; Markus Bohlin; Franz Wotawa; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Testing; Optimization; Integration Testing; Decision Support System; Dependency; Test Scheduling; Requirement Coverage; Computer Science;

   Abstract : Optimizing software testing process has received much attention over the last few decades. Test optimization is typically seen as a multi-criteria decision making problem. One aspect of test optimization involves test selection, prioritization and execution scheduling. READ MORE

7. 5. Optimization and Control in Dynamical Network Systems

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

   Abstract : 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.
