  1. 1. Injection Strategies for Heavy Duty DI Diesel Engines

    Författare :Tanja Rente; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multiple injections; injection pressure; local heat transfer; diesel combustion; injection duration; orifice number; injection strategies;

    Sammanfattning : Diesel engines enjoy widespread popularity in transportation and industrial systems. The reasons for this popularity are their simplicity, relatively low capital costs, durability and high fuel efficiency. LÄS MER

  3. 2. Pain induced by propofol - clinical studies on drug composition and adminstration

    Författare :Elisabeth Liljeroth; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intravenous; Medicin människa och djur ; Medicine human and vertebrates ; pain; propofol; injection;

    Sammanfattning : Over the last 25 years a number of new anaesthetic drugs have been introduced on the market to allow for better patient satisfaction and faster recovery after anaesthesia and sedation. Propofol (2,6-di-isopropylphenol), one of our most common iv anaesthetics, is associated with pleasant sleep and rapid recovery with little postoperative nausea. LÄS MER

  4. 3. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis

    Författare :Erik Svensson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Compression ignition; Direct injection; Methanol; Engine optimization; Stochastic reactor model; T-phi diagrams; Partially premixed combustion; Compression Ignition; Direct Injection; Methanol; Engine Optimization; Stochastic reactor model; Gas exchange; T-phi diagrams;

    Sammanfattning : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. LÄS MER

  5. 4. On Impact and Tolerance of Data Errors with Varied Duration in Microprocessors

    Författare :Örjan Askerdal; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dependability; error propagation analysis; fault tolerance; error effect analysis;

    Sammanfattning : The evolution of high-performance and low-cost microprocessors has led to their almost pervasive usage in embedded systems such as automotive electronics, smart gadgets, communication devices, etc. These mass-market products, when deployed in safety-critical systems, require safe services albeit at low recurring costs.
