  2. 1. Topology optimization in fluid flow problems

    Author : Niclas Wiker; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In this thesis, the topic of topology optimization in fluids is studied. With emphasis on modeling aspects, the general framework for formulating such problems is presented through a derivation of a sample problem. A survey of the literature, summarizing the developments in the area, forms the first part of the thesis. READ MORE

  4. 2. Studies on Design Automation of Analog Circuits : the Design Flow

    Author : Emil Hjalmarson; Svensson Mattiasson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : During the past few years the concept of system-on-chip (SoC) have become an important segment in the market of integrated circuits. This recent development have increased not only the number of devices and the functionality that can be put on a chip, but the chips now includes both digital and analog circuits. READ MORE

  5. 3. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

    Author : Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation automation systems; IEC 61850; electrical topology; electrical engineering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.

  6. 4. Approximation of topology optimization problems using sizing optimization problems

    Author : Anton Evgrafov; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structural optimization; bilevel programming; approximation; topology optimization; control in coefficients; optimal design; fictitious domain; control in coefficients;

    Abstract : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. READ MORE

  7. 5. Topology Prediction of Membrane Proteins: Why, How and When?

    Author : Karin Melén; Gunnar von Heijne; Hugh Salter; Janet Thornton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; topology prediction; bioinformatics; Theoretical chemistry; Teoretisk kemi; biokemi; Biochemistry;

    Abstract : Membrane proteins are of broad interest since they constitute a large fraction of the proteome in all organisms, up to 20-30%. They play a crucial role in many cellular processes mediating information flow and molecular transport across otherwise nearly impermeable membranes. READ MORE
