  1. 16. Gear engagement control for transmissions in hybrid electric vehicles

    Författare :Muddassar Piracha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

    Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER

  3. 17. Analysis and Design of Hybrid Systems

    Författare :Stefan Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

    Sammanfattning : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. LÄS MER

  4. 18. Wind Power and Natural Disasters

    Författare :Jon Olauson; Mikael Bergkvist; Stefan Ivanell; Uppsala universitet; []
    Nyckelord :Wind power; Natural disasters; Hybrid energy system; Meteorological model; Statistical model; Variability; Wind power integration;

    Sammanfattning : Wind power can be related to natural disasters in several ways. This licentiate thesis gives some background and introduces four papers devoted to two aspects of this relation. The first section looks into how small-scale wind energy converters (WECs) could be used to generate power after a natural disaster. LÄS MER

  5. 19. Modern GIR Systems : Framework, Retrieval Model and Indexing Techniques

    Författare :Xing Lin; Yifang Ban; Harrie Lars; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Retrieval; GIR; Framework; Indexing; Retrieval Model; Other information technology; Övrig informationsteknik;

    Sammanfattning : Geographic information is one of the most important and the most common types of information in human society. It is estimated that more than 70% of all information in the world has some kind of geographic features. LÄS MER

  7. 20. Mathematical Modelling of Cellular Ageing: a Multi-Scale Perspective

    Författare :Barbara Schnitzer; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; replicative ageing; healthy ageing; yeast; complex systems; multi-scale model; hybrid model; flux balance analysis; ordinary differential equations; Boolean modelling;

    Sammanfattning : In a growing and increasingly older population, we are progressively challenged by the impact of ageing on individuals and society. The UN declared the years 2021-2030 as the Decade of Healthy Ageing, highlighting the efforts to minimise the burden of ageing and age-related diseases. LÄS MER
