  2. 21. A study on wear characteristics of high strength steels under sliding contact

    Author : Abdulbaset Mussa; Pavel Krakhmalev; Jens Bergström; Jens Hardell; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High strength steels; thread joint wear; punch wear; sliding wear; surface cracking; reciprocal sliding; fatigue; surface delamination; white etching layer; nano-structured layer; friction; Materialteknik; Materials Engineering;

    Abstract : In the last decades, significant improvements regarding the design, materials and technology of rock drills have been made. Likewise, in sheet metal forming, forming tools experience very high contact pressures when processing high strength steel sheets. READ MORE

  4. 22. cancer subtype identification using cluster analysis on high-dimensional omics data

    Author : Linda Vidman; Patrik Rydén; Jun Yu; Erik Kristiansson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cluster analysis; cancer; classification;

    Abstract : Identification and prediction of cancer subtypes are important parts in the development towards personalized medicine. By tailoring treatments, it is possible to decrease unnecessary suffering and reduce costs. Since the introduction of next generation sequencing techniques, the amount of data available for medical research has increased rapidly. READ MORE

  5. 23. Structured Learning for Structural Bioinformatics : Applications of Deep Learning to Protein Structure Prediction

    Author : David Menéndez Hurtado; Arne Elofsson; Sergei Grudinin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

    Abstract : Proteins are the basic molecular machines of the cell, performing a broad range of tasks, from structural support to catalysisof chemical reactions. Their function is determined by their 3D structure, which in turn is dictated by the order of their components, the amino acids. READ MORE

  6. 24. Performance analysis of a low-speed high-torque hydrostatic transmission unit

    Author : Håkan Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. READ MORE

  7. 25. Distributed Control of HVDC Transmission Grids

    Author : Davood Babazadeh; Lars Nordström; Oriol Gomis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-simulation; cyber-physical system; DC slack bus; distributed control; HVDC grids; power injection; topology processor; wind farms; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Recent issues such as priority access of renewable resources recommended by European energy directives and increase the electricity trading among countries lead to new requirements on the operation and expansion of transmission grids. Since AC grid expansions are limited by legislative issues and long distance transmission capacity, there is a considerable attention drawn to application of HVDC transmission grids on top of, or in complement to, existing AC power systems.
