  1. 1. Software Engineering in Start-up Companies

    Författare :Eriks Klotins; Tony Gorschek; Michael Unterkalmsteiner; Anthony Wasserman; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; start-ups; software engineering; practices; models;

    Sammanfattning : Start-up companies have emerged as suppliers of innovation and software-intensive products. Small teams, lack of legacy products, experimental nature, and absence of any organizational processes enable start-ups to develop and market new products and services quickly. However, most start-ups fail before delivering any value. LÄS MER

  3. 2. Run-Up Transient Analysis for Salient Pole Wound Field Synchronous Motors : Field winding and power electronics implications for a smoother and cooler asynchronous start

    Författare :Roberto Felicetti; Urban Lundin; Andreas Binder; Uppsala universitet; []
    Nyckelord :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; asynchronous start; run-up; torque ripple; reluctance torque; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Salient Pole Wound Field Synchronous Machines have better efficiency at full load than asynchronous machines of the same capability. Moreover, where asynchronous machines need inherently to draw a magnetizing current from the grid, Salient Pole Wound Field Synchronous Machines can work efficiently at unity power factor. LÄS MER

  4. 3. Cold Load Pick-up

    Författare :Evert Agneholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cold load pick-up; load modelling; field measurements; blackout; power system restoration;

    Sammanfattning : The load behaviour of the industrial and residential sector following different types of outages is dealt with in this dissertation. Data on the power consumption after these outages have been used for deriving models of the cold load pick-up. LÄS MER

  5. 4. Tillväxtföretag i startfas : från dimma och mörker till relationslyft : ett tjugofemårigt perspektiv på paradoxer och dilemman i processen från uppfinning till innovation

    Författare :Leif Rylander; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Tillväxtföretag; Tekniska innovationer; ekonomiska aspekter; Företagande; Företagsetablering; Högteknologi;

    Sammanfattning : The importance of high-technology growth companies is emphasized throughout the Western World. In Sweden an industrial company with proprietary products, which achieves sales of SEK 1 billion, only emerges about once every ten years. LÄS MER

  7. 5. Pilot Production and Manufacturing Start-up in the Automotive Industry. Principles for Improved Performance

    Författare :Henrik Almgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; disturbance control; performance; verification; manufacturing start-up; learning; pilot production; Swedish automotive industry; product and production preparation;

    Sammanfattning : The dissertation is based on experiences from Volvo Car Corporation and examines pilot production and manufacturing start-up, processes that are here combined under the rubric final verification of product and production system. The purpose of this dissertation is to study pilot production and manufacturing start-up in order, first, to identify and analyze factors affecting final verification performance and, secondly, to develop general principles for how final verification performance can be improved.
