  1. 1. Program Analysis for Performance and Reliability

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Jacob Lidman; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static dynamic program analysis; abstract interpretation; performance; reliability;

    Sammanfattning : The increased demand for computing power has lead designers to put an ever increasing number of cores on processor dies. This advance has been made possible through miniaturization and effectivization of the underlying semi-conductor technology. As a by-product, however, the resulting computer systems are more vulnerable to interference. LÄS MER

  2. 2. Structural Safety Analysis of Bow-Doors

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Ulf Karlsson; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship design; structure; safety; fatigue.; arm; IACS S8; damage; bow-door; analysis;

    Sammanfattning : Bow-doors are one of the most vulnerable parts on a RoRo-vessel. At the same time, they are necessary for the profitability of todays RoRo-vessels.The minimum design rules for bow-door systems, stated in the International Association of Classification Societies (IACS) S8, constitute the basis for the class rules.
