2. 1. Design of Multi-layer Telecommunication Networks: Fairness, Resilience, and Load Balancing

   Author : Eligijus Kubilinskas; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; network design; multi-layer networks; fairness; resilience; telecommunications; load balancing; optimization;

   Abstract : Migration to Next Generation Internet architectures poses new challenges for network operators in planning core networks and calls for efficient network planning and optimization tools. Optimization models underlying such tools are developed in this thesis. READ MORE

4. 2. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

   Author : Stavros Tzilis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

   Abstract : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.

5. 3. Thermal and State-of-Charge Balancing of Batteries using Multilevel Converters

   Author : Faisal Altaf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal balancing; Convex optimization; DC-link ripple; Battery ripple; Battery control; Hybrid electric vehicles.; Multilevel converter; Cell balancing;

   Abstract : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. READ MORE

6. 4. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

   Author : Faisal Altaf; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; converters; electrified vehicles.; model predictive control; thermal balancing; SOC balancing; battery control; Modular batteries;

   Abstract : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. READ MORE
