  2. 11. Structure determination of ribosomal proteins and development of new methods in biomolecular NMR

    Author : Magnus Helgstrand; KTH; []
    Keywords : nuclear magnetic resonance; structure determination; ribosomal proteins; NMR simulations; NMR theory; NMR assignment software; semiautomatic assignment;

    Abstract : This thesis concerns different areas of biomolecular nuclearmagnetic resonance spectroscopy (NMR). In the first part of thethesis a new formalism for simulations of NMR pulse sequencesis introduced. The formalism is derived both from classicalmechanics and quantum mechanics and is presented forhomonuclear and heteronuclear spin systems. READ MORE

  4. 12. New Insights on Computerized Trading : Implications of Frequently Revised Trading Decisions

    Author : Petter Dahlström; Björn Hagströmer; Lars Nordén; Andriy Shkilko; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Administration; företagsekonomi;

    Abstract : Computerized trading may be viewed as an aspect of modernization of financial markets. This dissertation contains four articles that in different ways examine to what extent the modernization influences the economics of the markets. READ MORE

  5. 13. Predictive Modelling to Support Design and Manufacturing in Aerospace Engineering

    Author : Siva Krishna Dasari; Abbas Cheddad; Lars Lundberg; Stan Matwin; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surrogate modelling; defects classification; machine learning; aerospace; additive manufacturing; Computer Science; Datavetenskap;

    Abstract : A crucial issue in the design of aircraft components is the evaluation of a large number of potential design alternatives.  This evaluation involves too expensive procedures, consequently, it slows down the search for optimal design samples. READ MORE

  6. 14. Structure-acoustic analysis; finite element modelling and reduction methods

    Author : Peter Davidsson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; low frequency range; building acoustics; lightweight structures; porous materials; modal reduction; substructuring; finite element analysis; structural acoustics; vibroacoustics; Structural dynamics;

    Abstract : This thesis investigates structure-acoustic systems by use of finite element analysis. The systems studied here are limited to those that consist of an enclosed acoustic fluid cavity, which is coupled to a flexible structure and/or a porous sound absorbing material domain. READ MORE

  7. 15. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics

    Author : Roberto Felicetti; Urban Lundin; Jon Kjellin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency;

    Abstract : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. READ MORE
