  2. 12. 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.

    Abstract : This thesis consists of an introduction and five research papers on topics related to conformal mapping, the Loewner equation and its applications, and Bergman-type spaces of holomorphic functions. The first two papers are devoted to the study of integral means of derivatives of conformal mappings. READ MORE

  5. 15. Novel concepts for advanced CMOS : Materials, process and device architecture

    Author : Dongping Wu; KTH; []
    Keywords : CMOS technology; MOSFET; high-k; gate dielectric; ALD; surface pre-treatment; metal gate; poly-SiGe; strained SiGe; surface-channel; buried-channel; notched gate;

    Abstract : The continuous and aggressive dimensional miniaturization ofthe conventional complementary-metal-oxide semiconductor (CMOS)architecture has been the main impetus for the vast growth ofIC industry over the past decades. As the CMOS downscalingapproaches the fundamental limits, unconventional materials andnovel device architectures are required in order to guaranteethe ultimate scaling in device dimensions and maintain theperformance gain expected from the scaling.
