1. 1. Aging sensitive battery control

   Författare :Malin Andersson; Mikael Johansson; Matteo Corno; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; battery control; parameter identification; equivalent circuit model; Doyle-Fuller-Newman model; sensitivity analysis; optimal experiment design; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : The battery is a component with significant impact on both the cost and environmental footprint of a full electric vehicle (EV). Consequently, there is a strong motivation to maximize its degree of utilization. Usage limits are enforced by the battery management system (BMS) to ensure safe operation and limit battery degradation. LÄS MER

3. 2. Electromechanics of Vertical Axis Wind Turbines

   Författare :Morgan Rossander; Sandra Eriksson; Hans Bernhoff; Daniel Karlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind power; Diode rectification; Control; Measurement; Simulation; Electromechanical coupling; vindkraft; diodlikriktning; reglering; mätning; simulering; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maintenance is high and future wind turbines may need to be improved to enable more remote and offshore locations. LÄS MER

4. 3. Embedded Systems and FPGAs for Implementation of Control Oriented Models, Applied to Combustion Engines

   Författare :Carl Wilhelmsson; Förbränningsmotorer; []
   Nyckelord :NOx; NO; Nitrogen Oxides; Emissions; Air pollution; Algorithms; Physical model; Mathematical model; FPGA; Field Programmable Gate Arrays; Embedded Systems; Micro-controllers; Engine; Diesel Engine; Internal Combustion Engine; Combustion Control; Engine Control.;

   Sammanfattning : Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. LÄS MER

5. 4. Cognitive training in young and old adults : Transfer, long-term effects, and predictors of gain

   Författare :Petra Sandberg; Anna Stigsdotter Neeyl; Michael Rönnlund; Boo Johansson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive training; aging; old adults; executive function; life-span; individual differences; episodic memory; inhibition; shifting; updating; cognitive control; strategy training; mnemonics; predictors; Psychology; psykologi;

   Sammanfattning : Aging, also in the absence of pathological conditions, is associated with cognitivedecline, especially in so called fluid abilities, such as episodic memory andexecutive functions. Due to an ongoing demographic shift, a larger part of thepopulation will reach higher ages, and more people will be affected by age-relatedcognitive decline. LÄS MER

7. 5. Modelling, parameter identification and aging-sensitive management of lithium-ion batteries in heavy-duty electric vehicles

   Författare :Malin Andersson; Mikael Johansson; Davide Raimondo; KTH; []
