  2. 1. A model for simulation and generation of surrounding vehicles in driving simulators

    Author : Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Keywords : Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. READ MORE

  4. 2. Micro-grids supplied by renewable energy : Improving technical and social feasibility

    Author : Caroline Bastholm; Ewa Wäckelgård; Annette Henning; Frank Fiedler; Kirsten Ulsrud; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; Electricity access; Decentralized; Off-grid; Photovoltacs; PV-hybrid; Micro-grid; Multi-disciplinary; Sociotechnical; Engineering Science; Teknisk fysik; Energy and Built Environments;

    Abstract : Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. READ MORE

  5. 3. On the deformation behavior and cracking of ductile iron; effect of microstructure

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical graphite iron; component casting; high silicon ductile iron; digital image correlation DIC ; in-situ tensile testing; in-situ cyclic testing; DIC pattern generation; pit etching; micro-scale deformation; micro-crack; finite element analysis FEA ; focused ion beam FIB milling; segjärn; komponentgjutning; högkisellegerat segjärn; digital image correlation DIC ; insitu dragprovning; in-situ cyklisk provning; DIC-mönstergenerering; grop-etsning; mikroskalig deformation; mikrosprickor; finite element analys FEA ; fokuserad jonstråle FIB avverkning;

    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

  6. 4. RVE generation and computational homogenization of structural battery electrolytes

    Author : Vinh Tu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrochemical transport; structural battery electrolyte; Li-ion based structural batteries; computational homogenization; RVE generation;

    Abstract : The structural battery is multifunctional in the sense that it is able to carry mechanical loads, and at the same time store and deliver energy. This is made possible due to carbon fibers' ability to act not only as structural reinforcement materials, but also as electrode components. READ MORE

  7. 5. Low-temperature based thermal micro-grids: operation and performance assessments

    Author : José Fiacro Castro Flores; Viktoria Martin; Bruno Lacarrière; Justin NingWei Chiu; Vittorio Verda; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; active thermal micro-grid; substation operation; performance assessment; distributed heat resources; chauffage urbain basse température; micro-réseaux de chaleur urbains actifs; fonctionnement de la sous-station; évaluation de la performance; sources de chaleur distribuées; lågtemperatur fjärrvärme; aktiv fjärrvärmemikronät; fjärrvärmecentral operation; prestationsbedömning; distribuerada värmekällor; Energy Technology; Energiteknik;

    Abstract : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. READ MORE
