2. 11. May the power be with you : managing power-performance tradeoffs in cloud data centers

   Author : Jakub Krzywda; Erik Elmroth; Per-Olov Östberg; Ahmed Ali-Eldin; Tarek F. Abdelzaher; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; data centers; power efficiency; power budgeting; application performance;

   Abstract : The overall goal of the work presented in this thesis was to find ways of managing power-performance tradeoffs in cloud data centers. To this end, the relationships between the power consumption of data center servers and the performance of applications hosted in data centers are analyzed, models that capture these relationships are developed, and controllers to optimize the use of data center infrastructures are proposed.

5. 13. Analysing, modelling and controlling power-performance tradeoffs in data center infrastructures

   Author : Jakub Krzywda; Erik Elmroth; Per-Olov Östberg; Ahmed Ali-Eldin; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The aim of this thesis is to analyse the power-performance tradeoffs in datacenter servers, create models that capture these tradeoffs, and propose controllers to optimise the use of data center infrastructures taking the tradeoffs into consideration. The main research problem that we investigate in this thesis is how to increase the power efficiency of data center servers taking into account the power-performance tradeoffs. READ MORE

7. 15. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry

   Author : Kaveh Torkashvand; Mohit Kumar Gupta; Shrikant V. Joshi; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribological Behaviour; HVAF; WC-Based Coatings; Process Variables; Binder Chemistry; Tribologisk Prestanda; HVAF; WC-baserade Beläggningar; Parametervariabler; Bindemedelskemi; Production Technology; Produktionsteknik;

   Abstract : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. READ MORE
