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

   Författare :Mladen Čičić; Karl Henrik Johansson; Miroslav Krstić; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 37. Simulation-based Optimization and Decision Making with Imperfect Information

   Författare :Farzad Kamrani; Rassul Ayani; Stephen John Turner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

   Sammanfattning : The purpose of this work is to provide simulation-based support for making optimal (or near-optimal) decisions in situations where decision makers are faced with imperfect information. We develop several novel techniques and algorithms for simulation-based optimization and decision support and apply them to two categories of problems: (i) Unmanned Aerial Vehicle (UAV) path planning in search operations, and; (ii) optimization of business process models.

4. 38. Phase Noise and Wideband Transmission in Massive MIMO

   Författare :Antonios Pitarokoilis; Erik G. Larsson; Gerhard Kramer; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In the last decades the world has experienced a massive growth in the demand for wireless services. The recent popularity of hand-held devices with data exchange capabilities over wireless networks, such as smartphones and tablets, increased the wireless data traffic even further. This trend is not expected to cease in the foreseeable future. LÄS MER

5. 39. Turbulent and Transitional Flow in Porous Media An Experimental Investigation

   Författare :Shervin Khayamyan; Wook Ryol Hwang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Fluid flow through porous media takes place in many natural processes such as ground water flows, capillary flows in plants and flow in human organs and muscles. It is also of outmost importance to have knowledge of this flow in a number of industrial processes such as paper making, making of fiber boards, composites manufacturing, filtering, forming and sintering of iron ore pellets and drying and impregnation of wood.

7. 40. Aging and Characterization of Semiconducting Glazes

   Författare :Heike Ullrich; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Semiconducting glazes on ceramic insulators had been introduced as a solution for improving the performance of high voltage insulators especially under heavily polluted conditions. The major concern in using such glazes, despite their approved advantages, is the observed aging of the surface with exposure time, leading to reduction of conductivity and deterioration of the glaze itself, especially under dc voltage.
