    Sammanfattning : This dissertation provides a capability creation perspective on the story of China’s technological catching up, or resurgence, if viewed from a broader historical perspective.Since the first Asian tigers caught up to modern technological standards (e.g. LÄS MER

  3. 2. Control of vehicle platoons and traffic dynamics : catch-up coordination and congestion dissipation

    Författare :Mladen Čičić; Karl H. Johansson; Daniel Work; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Congestion; Intelligent Transport Systems; Moving Bottlenecks; Platoon Coordination; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array ofnegative effects on the society, from wasted time and productivity to elevated air pollution and increased number of accidents. Classical traffic control methods have long been successfully employed to alleviate congestion, improving the traffic situation of many cities and highways. LÄS MER

  4. 3. Att elda för kråkorna? : hushållens energianvändning inom bostadssektorn i Sverige 1913-2008

    Författare :Mikael Levin; Magnus Lindmark; Ann-Kristin Bergquist; Astrid Kander; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic History; households; energy consumption; consumption patterns; housing; housing and energy policy; carbon dioxide emissions; Ekonomisk historia; hushåll; energikonsumtion; konsumtionsmönster; hushåll och energipolitik; koldioxidutsläpp; ekonomisk historia; Economic History;

    Sammanfattning : This thesis investigates the development of the long-term energy consumption in the Swedish households by estimating the sector’s total energy use and moreover, by examining how structural, institutional and economic factors have affected the demand for energy in the residential sector during the period 1913-2008. The investigated period covers a transition from traditional fuels, such as firewood, to fossil fuels and finally renewable energy. LÄS MER

  5. 4. Catching the invisible - aerodynamic tracks and kinematics of bat and bird flight

    Författare :Marta Wolf; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flight; bats; birds; kinematics; vertebrates; aerodynamics;

    Sammanfattning : This thesis is about the flight of vertebrates and the studies of different modes of flight. Flight has always fascinated mankind and this fascination gave inspiration for our attempts at flying. LÄS MER

  7. 5. Solution Chemistry and Morphological Properties for Organic Solar Cells : Exploring Alternative Solvents Using Microgravity and Modelling as Tools

    Författare :Ishita Jalan; Jan van Stam; Patricia Saenz Mendez; Stela Andrea Muntean; Mariano Campoy-Quiles; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solution chemistry; green solvents; microgravity; OPV; HSP; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Sammanfattning : Organic photovoltaics (OPVs) have the advantage of the accessibility of energy for all, due to facile and low-cost processing, with its low energy payback time compared to other technologies, therefore promising applications. Research and development have led to power conversion efficiencies of nearly 20% and now catching up to their inorganic counterparts. LÄS MER
