  1. 1. Duplicate systems investigating unintended consequences of information technology in organizations

    University dissertation from Umeå : Institutionen för informatik, Umeå universitet

    Author : Henrik Wimelius; Umeå universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; IS and organization; adoption of IT; assimilation of IT; change; dialectics; paradox; duplicate systems; contradiction; unintended consequences; information systems; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Informatics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informatik;

    Abstract : The organizational consequences of information technology (IT) constitutes a core focus in information systems (IS) research. The relationship between organizations and IT has received considerable attention by IS researchers in order to develop knowledge related to how and why organizations and IT are related. READ MORE

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

    University dissertation from Västerås : Mälardalen University

    Author : Andreas Gustavsson; Mälardalens högskola.; [2014]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 3. Timing Analysis of Distributed Embedded Systems with Stochastic Workload and Realiability Constraints

    University dissertation from Linköping : Linköping University Electronic Press
