  3. 2. Thermal System Analysis : heat transfer in glass forming and fluid temperature-control systems

    Författare :Karl Storck; Rolf Karlsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Thermal system analyses are often required, and conducted, in engineering problems in almost all engineering disciplines. The methods employed vary a great deal and must be specially adapted for each situation. Basically, two different methods are used, namely distributed modelling and lumped parameter modelling.

  4. 3. Survival of the Unfit : Path Dependence and the Estonian Oil Shale Industry

    Författare :Rurik Holmberg; Staffan Laestadius; Mats Bladh; Mats Söderström; Nick von Tunzelmann; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Estonia; oil shale; path dependence; lock-in; institutions; knowledge; Sweden; innovation; Soviet Union; technology; systems; energy; shale oil; electricity; fossil fuel; environment; economy; Technology and social change; Teknik och social förändring;

    Sammanfattning : Estonia is the only country in the world, which is totally dependent on oil shale in its energy system. Although this fossil fuel exists in enormous quantities around the world, it has so far not been utilized on a larger scale. The reasons for this have been both economic and, in recent times, ecological. LÄS MER

  5. 4. Coupled Simulations of Cooling and Engine Systems for Unsteady Analysis of the Benefits of Thermal Engine Encapsulation

    Författare :Blago Minovski; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oil system; Cooling system; Drive cycle; CFD simulations; Fuel consumption; Engine encapsulation; 1D simulations;

    Sammanfattning : A well-designed engine encapsulation can extend engine cool-down time significantly - on the order of 500 - 700%. This is expected to have a sensitive influence on the fuel consumption due to the increased probability for high oil temperatures at the following engine start, reduced length of the initial warm-up period and consequently, reduced friction losses.

  7. 5. Essays on African Growth, Productivity, and Trade

    Författare :Ludvig Söderling; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomiska system; ekonomisk teori; ekonometri; Nationalekonomi; Africa; economic policy; economic systems; economic theory; econometrics; Economics; trade; gravity model; general equilibrium model; oil; diversification; Dutch disease; productivity; ekonomisk politik; International commerce; Internationell ekonomi; Economics of development; Utvecklingsekonomi; growth;

    Sammanfattning : The thesis comprises an introductory chapter and four research papers. The introductory chapter provides a brief overview of recent economic growth performance in Africa, places the individual papers into a coherent context, summarizes the main findings, and discusses their relevance for economic policy.
