  1. 11. School Reform, Educational Achievement and Lifetime Income : Essays in Empirical Labor Economics

    Författare :Anders Böhlmark; Anders Björklund; Dan-Olof Rooth; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economics of education; international migration; lifetime income; Economics; Nationalekonomi; Economics; nationalekonomi;

    Sammanfattning : The Impact of School Choice on Pupil Achievement, Segregation and Costs: Swedish Evidence. This paper evaluates school choice at the compulsory school level. We estimate the impact of an increased enrolment in private schools on average achievement using within-municipality variation over time. LÄS MER

    Sammanfattning : Recently, wireless sensor network (WSN) has become a promising technology with a wide range of applications such as supply chain monitoring and environment surveillance. It is typically composed of multiple tiny devices equipped with limited sensing, computing and wireless communication capabilities. LÄS MER

  5. 14. Assessment of the lifetime of district heating pipes

    Författare :Alberto Vega; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FTIR; rigid polyurethane foam; artificial ageing; {District heating pipes; natural ageing; degradation mechanisms; mechanical performance;

    Sammanfattning : This thesis is concerned with the degradation and assessment of the lifetime of district heating pipes, where accelerated ageing is used to study the degradation in a short time frame. The project was divided into four interrelated parts. LÄS MER

  7. 15. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Författare :Stavros Tzilis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

    Sammanfattning : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.
