1. 21. Reconfigurable Motion Control Systems for Over-Actuated Road Vehicles

   Författare :Leo Laine; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; over-actuated; road vehicle; reconfigurable; control allocation; hybrid electric vehicle; motion control system;

   Sammanfattning : Over-actuated systems, such as today's road vehicle configurations, have more motion actuators than controlled motions. For example, a passenger car has a combustion engine and four mechanical brakes, all of which can be used individually to correct any error in yaw rate when the vehicle becomes under- or oversteered.

3. 22. The Frequency of the Frequency : On Hydropower and Grid Frequency Control

   Författare :Linn Saarinen; Urban Lundin; Per Norrlund; Bengt Carlsson; Kjetil Uhlen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydropower; frequency control; governors; power system stability; inertia; primary control; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Variations in the electricity consumption and production connected to the power system have to be balanced by active control. Hydropower is the most important balancing resource in the Nordic system, and will become even more important as the share of variable renewable energy sources increases. LÄS MER

4. 23. Dynamic modeling of Internet congestion control

   Författare :Krister Jacobsson; Håkan Hjalmarsson; Douglas Leith; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Congestion control; TCP; Control theory; Fluid flow modeling; Internet; Telecommunication; Telecommunication; Telekommunikation;

   Sammanfattning : The Transmission Control Protocol (TCP) has successfully governed the Internet congestion control for two decades. It is by now, however, widely recognized that TCP has started to reach its limits and that new congestion control protocols are needed in the near future. LÄS MER

5. 24. Resource Allocation in Airborne Surveillance Radar

   Författare :Johannes Wintenby; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar resource management; radar control; sensor management; surveillance radar; electronically scanned antenna; adaptive tracking; resource allocation;

   Sammanfattning : Radars equipped with an Electronically Scanned Antenna (ESA) have the potential of directing the electromagnetic radar beam without mechanically adjusting the antenna. Furthermore, the beam can be redirected instantaneously towards any location in space. LÄS MER

7. 25. Revenue Maximization in Resource Allocation : Applications in Wireless Communication Networks

   Författare :Nilo Casimiro Ericsson; Anders Ahlén; Mikael Sternad; Jens Zander; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; wireless; resource; scheduling; revenue; admission control; service level control; service level agreement; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

   Sammanfattning : Revenue maximization for network operators is considered as a criterion for resource allocation in wireless cellular networks. A business model encompassing service level agreements between network operators and service providers is presented. LÄS MER
