    Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  4. 2. Efficiency of heat and work in a regional energy system

    Author : Tommy Rosén; Louise Ödlund; Shahnaz Amiri; Erik Dotzauer; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the largest flows of energy in Swedish municipalities is the fuel-energy flow through the regional combined heat and power (CHP) plant. The customer products from this flow are mainly electricity to the electricity grid and heat to the building sector. READ MORE

  5. 3. System studies of the use of industrial excess heat

    Author : Sarah Broberg Viklund; Magnus Karlsson; Mats Söderström; Semida Silveira; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; waste heat; surplus heat; energy systems; greenhouse gas emissions; energy efficiency; energy policy; system studies;

    Abstract : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. READ MORE

  6. 4. Evaluation of new active technology for low-energy houses

    Author : Henrik Davidsson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-quality heat; hybrid ventilation; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE

  7. 5. Biomedical and atmospheric applications of optical spectroscopy in scattering media

    Author : Johannes Swartling; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Turbid media; Tissue optics; Tissue optical properties; Multiple scattering; Radiative transfer; Diffusion equation; Monte Carlo method; Time-resolved spectroscopy; Atomic and molecular physics; Integrating spheres; Atom- och molekylärfysik; Fysicumarkivet A:2002:Swartling;

    Abstract : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. READ MORE
