  1. 6. Perpetual product development : a study of small technology-driven firms

    Författare :Jan Bodin; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perpetual product development; technology; aircraft industry; small firms; inventor; key actors; resources;

    Sammanfattning : This dissertation focuses the attention toward inventors and key actors involved in product development projects. The study focuses on how a new product development process is carried out operationally and strategically in small, technology-driven firms. LÄS MER

  3. 7. Techniques for finite element methods on modern processors

    Författare :Karl Ljungkvist; Jarmo Rantakokko; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : In this thesis, methods for efficient utilization of modern computer hardware for numerical simulation are considered. In particular, we study techniques for speeding up the execution of finite-element methods. LÄS MER

  4. 8. Driver Experience and Acceptance of Driver Support Systems - A Case of Speed Adaptation

    Författare :Emeli Adell; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed support; ISA; driver support systems; Driver experiences; acceptance; UTAUT; ADAS; field trial;

    Sammanfattning : Substantial research and development efforts are being made to add driver support systems to the arsenal of traffic safety measures. Obviously, the system cannot reduce fatalities and trauma until it is actually used. Hence, drivers’ experiences and acceptance of the system are of paramount importance. LÄS MER

  5. 9. Centrifugal pendulum vibration absorbers in heavy-duty truck powertrains : Modelling, simulation and experimental investigations

    Författare :Erik Gomez; Leif Kari; Ines Lopez Arteaga; Ole Balling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; centrifugal pendulum vibration absorber CPVA ; powertrain; heavy-duty truck; driveline; transmission; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The heavy-duty vehicle industry is facing big challenges to reduce CO2 emissions. Although electrification is on the rise, the combustion engine will used for some time to come. LÄS MER

  7. 10. Structure determination of ribosomal proteins and development of new methods in biomolecular NMR

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

    Sammanfattning : 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. LÄS MER
