  1. 1. Static Execution Time Analysis of Parallel Systems

    Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; David Broman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Sammanfattning : The past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism is no longer feasible due to extensive power consumption and heat dissipation. Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

  3. 2. Static Timing Analysis of Parallel Systems Using Abstract Execution

    Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; Nan Guan; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Sammanfattning : The Power Wall has stopped the past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism.Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

  4. 3. On the Simulation of Progressive Deformation in Nuclear Piping

    Författare :Andreas Gustafsson; Jan Granlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : In this thesis the performance of different constitutive models in ratchet simulation is investigated. Ratcheting is accumulated plastic strains which may occur when a structure is subjected to a constant load in combination with cyclic loading. LÄS MER

  5. 4. Iron Based Materials for Positive Electrodes in Li-ion Batteries : Electrode Dynamics, Electronic Changes, Structural Transformations

    Författare :Andreas Blidberg; Fredrik Björefors; Torbjörn Gustafsson; Carl Tengstedt; Miran Gaberšček; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion; batteries; electrochemistry; iron; LiFeSO4F; Li2FeP2O7; PEDOT; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Li-ion battery technology is currently the most efficient form of electrochemical energy storage. The commercialization of Li-ion batteries in the early 1990’s revolutionized the portable electronics market, but further improvements are necessary for applications in electric vehicles and load levelling of the electric grid.

  7. 5. An Automotive Lane Guidance System

    Författare :Andreas Eidehall; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; Collision avoidance; Lane guidance; State estimation; Target tracking; Kalman filter; Centralized filtering; Threat assessment; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Automotive lane guidance systems, usually referred to as Lane Keeping Aid or Lane Keeping System, are designed to prevent or warn the driver of lane departure. They typically use a buzzer to alert the driver or a steering wheel torque to actually steer the vehicle back into the center of the lane. LÄS MER
