  2. 1. 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.

  4. 2. Incident Traffic Flow Models

    Author : Azita Dabiri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic incident; ramp metering; macroscopic freeway traffic modeling; robust control; incident parameterization;

    Abstract : In the trend toward civilization, transportation has always been considered asan indisputable aspect. However, soon it turned out to be a dilemma in manymetropolitan areas how to assess the increased demand in transportation. The exigency for advanced alternative arises when constructing new roads and infrastructures lost its eligibility due to i. READ MORE

  5. 3. Thread-based mobility for a distributed dataflow language

    Author : Dragan Havelka; Seif Haridi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Datavetenskap; Computer science; Datavetenskap;

    Abstract : Strong mobility enables migration of entire computations combining code, data, and execution state (such as stack and program counter) between sites of computation. This is in contrast to weak mobility were migration is confined to just code and data. READ MORE

  6. 4. Sequential Data Learning, Scalable Models and Adversarial Regularization

    Author : Jin Huang; Ming Xiao; Geyong Min; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Time Series Prediction (TSP) has been used in mobile network traffic data analysis to produce predictive results for network planning and resource allocation. In the first part of this thesis, we propose a novel method of predicting mobile network traffic using neural networks based on conditional probability modeling between adjacent data windows in the time series sequence.

  7. 5. Lossy and Lossless Compression Techniques to Improve the Utilization of Memory Bandwidth and Capacity

    Author : Albin Eldstål-Ahrens; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Approximate Computing; Compression; Memory Systems;

    Abstract : Main memory is a critical resource in modern computer systems and is in increasing demand. An increasing number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates and greater memory capacity. READ MORE
