  1. 21. Methods for the Evaluation of Wingsails with a Crescent-Shaped Profile

    Författare :Heng Zhu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-assisted ship propulsion; rigid wingsail; light weight structure; crescent-shaped profile; wind-assisted ship propulsion.;

    Sammanfattning : Seaborne transportation accounts for a large proportion of greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has stipulated that GHG emissions should be reduced by 50% before 2050 compared to 2018. The use of wind-assisted ship propulsion (WASP) is considered one of the most effective ways to reduce GHG emissions. LÄS MER

  3. 22. Cotranslational protein biogenesis in Escherichia coli monitored by force profile analysis

    Sammanfattning : Proteins are a diverse class of biomolecules that carry out many essential functions across all organisms. They can either be found in aqueous compartments or embedded in biological membranes of the cell and are called soluble or membrane proteins, respectively. LÄS MER

  4. 23. Segmentation and fitting for geometric reverse engineering : processing data captured by a laser profile scanner mounted on an industrial robot

    Författare :Mohamed Rahayem; Johan Kjellander; Sören Hilmerby; Naoufel Werghi; Örebro universitet; []
    Nyckelord :Geometric Reverse Engineering; Industrial robot; Laser profile scanner; Segmentation; Fitting; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Geometric Reverse Engineering (GRE) is the problem of creating CAD models of real objects by measuring point data from their surfaces. The GRE process is usually divided into four sub processes, data capturing, preprocessing, segmentation, fitting and finally CAD model creation. To automate the GRE process the sub processes need to be integrated. LÄS MER

  5. 24. Electric Vehicle Charging Impact on Load Profile

    Författare :Pia Grahn; Lennart Söder; Ola Carlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One barrier to sustainable development is considered to be greenhouse gas emissions and pollution caused by transport, why climate targets are set around the globe to reduce these emissions. Electric vehicles (EVs), may be a sustainable alternative to internal combustion engine vehicles since having EVs in the car park creates an opportunity to reduce greenhouse gas emissions. LÄS MER

  7. 25. Road profile statistics relevant for vehicle fatigue

    Författare :Klas Bogsjö; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; Matematik; Mathematics; model evaluation; vehicle fatigue; stochastic processes; road roughness; Road profiles; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER
