  1. 1. Techniques to Cancel Execution Early to Improve Processor Efficiency

    Author : Mafijul Islam; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; processor design; energy-efficiency; narrow-width cache; instruction reuse; zero-value cache; resource-efficient; narrow-width load; complexity-effective; small value locality; register file cache; frequent value locality; trivial instruction; silent load; high-performance; zero load;

    Abstract : The evolution of computer systems to continuously improve execution efficiency has traditionally embraced various approaches across microprocessor generations. Unfortunately, contemporary processors still suffer from several inefficiencies although they offer an unprecedented level of computing capabilities. READ MORE

  2. 2. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

    Author : Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. READ MORE

  3. 3. Functioning in prosthetic users provided with and without a microprocessor-controlled prosthetic knee – relative effects on mobility, self-efficacy and attentional demand

    Author : Saffran Möller; Nerrolyn Ramstrand; Kerstin Hagberg; David Rusaw; Catharina Sjödahl Hammarlund; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amputation; trans-femoral amputation; adaptive prosthetic knee; prosthetic limb; self-report; mobility; self-efficacy; attention; brain; gait; neuroimaging; functional near-infrared spectroscopy; cognitive load; brain activity;

    Abstract : Background: To undergo a lower limb amputation is a traumatic experience affecting the individual on physical as well as psychological levels and often leading to limitations in a person´s daily life. Following an amputation individual often receive a prosthesis to address impairments in mobility and functioning. READ MORE

  4. 4. Experimental Results of a Load-Controlled Vertical Axis Marine Current Energy Converter

    Author : Johan Forslund; Mats Leijon; Karin Thomas; Jan Sundberg; Tom Blackmore; Uppsala universitet; []
    Keywords : Marine Current; Vertical Axis; Load Control; ; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : This thesis investigates the load control of a marine current energy converter using a vertical axis turbine mounted on a permanent magnet synchronous generator. The purpose of this thesis is to show the work done in the so far relatively uncharted territory of control systems for hydro kinetic energy conversion. READ MORE

  5. 5. Investigating Effects of Water Injection on SI Engines

    Author : Jayesh Khatri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knock Mitigation; Downsized SI engine; RON; Water Injection; Particulates; Relative Humidity;

    Abstract : In recent years, there has been a major shift towards the partial or complete electrification of vehicles that have traditionally been powered by conventional internal combustion (IC) engines; almost all major automotive manufacturers have rightly stated that they will make such a shift. This has been motivated in large part by pressure from governments and policymakers to minimize vehicular emissions, especially those of the greenhouse gas CO2, in order to control climate change.
