  2. 1. A Software Framework for Prioritized Spectrum Access in Heterogeneous Cognitive Radio Networks

    Author : Yong Yao; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cognitive Radio Networks; Queueing Modelling; Spectrum Decision; Fuzzy-Logic; Cellular Network; Ad-Hoc Network; Mesh Network;

    Abstract : Today, the radio spectrum is rarely fully utilized. This problem is valid in more domains, e.g., time, frequency and geographical location. READ MORE

  4. 2. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction

    Author : Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic control; Lagrangian control; mixed traffic models; Intelligent Transportation Systems; Connected and Automated Vehicles; traffic congestion; platoon coordination; moving bottlenecks; bottleneck decongestion; stop-and-go wave dissipation; traffic state reconstruction; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

  5. 3. Electric autonomous tractors in Swedish agriculture : A systems analysis of economic, environmental and performance effects

    Author : Oscar Lagnelöv; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Use of battery-electric vehicles has become common in different sectors, as a measure to reduce greenhouse gas emissions. Driveline electrification in agricultural machinery could reduce emissions and increase driveline efficiency, but implementation has been hindered by the low energy-carrying capacity of batteries compared with conventional fuels.

  6. 4. On some Control Problems for Queues

    Author : Bengt Bengtsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Queues; Control problems;

    Abstract : This thesis consists of three parts. In the first one, optimal policies are constructed for some singe-line queueing situations. The second part deals with finite-state Markovian decision processes, and in the third part the practical modelling of a more complex problem is discussed and exemplified. READ MORE

  7. 5. Performance Analysis and Design Space Exploration of On-Chip Interconnection Networks

    Author : Abbas Eslami Kiasari; Axel Jantsch; Joerg Henkel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The advance of semiconductor technology, which has led to more than one billion transistors on a single chip, has enabled designers to integrate dozens of IP (intellectual property) blocks together with large amounts of embedded memory. These advances, along with the fact that traditional communication architectures do not scale well have led to significant changes in the architecture and design of integrated circuits. READ MORE
