  1. 1. Athletic Sprint Start Biomechanics : Investigations into the relationships between three dimensional starting technique, first step width and performance

    Författare :Paul Nicolas Sandamas; Anton Arndt; Elena M. Gutierrez-Farewik; Aki Salo; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sprint start; step width; biomechanics; performance; angular momentum; Medicin Teknik; Medicine Technology;

    Sammanfattning : The block and early acceleration phase plays a very important role in the overall outcome of athletic sprint events. During this part of the race it is commonly observed that sprinters use a lower-body technique that involves the swing leg crossing medially in front of the athlete followed by wide steps. LÄS MER

  3. 2. 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

  4. 3. The efficient ethanol engine with cold start capability

    Författare :Jonas Wärnberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezo-actuated outward-opening direct injection; SI engine; Two-stage-turbo charging; Ethanol; Stratified Direct Injection; Cold start;

    Sammanfattning : In light of the world’s growing demand for personal transportation and the decreasing availability of fossil fuels, alternative fuels must be evaluated. Ethanol is a renewable fuel whose adoption could help to reduce the burden of anthropogenic activity on the environment. LÄS MER

  5. 4. Start-ups in Business Networks: Resource Development through Interaction

    Författare :Maria Landqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Resource Development; Resources; Interaction; Business Networks; Interfaces; Start-ups;

    Sammanfattning : This licentiate thesis deals with start-ups’ processes of relating to existing components in the business network in order to develop their innovations and become embedded in it. Previous research has shown that technology-based start-ups rely on external resources through collaborative business partners in order to create innovation. LÄS MER

  7. 5. Hollow cone gasoline/ethanol sprays under cold start conditions
