  1. 1. On Intelligent District Heating

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Christian Johansson; Blekinge Tekniska Högskola.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Intelligent district heating is the combination of traditional district heating engineering and modern information and communication technology. A district heating systemis a highly complex environment consisting of a large number of distributed entities, and this complexity and geographically dispersed layout suggest that they are suitable for distributed optimization and management.

  2. 2. Towards Intelligent District Heating

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Christian Johansson; Blekinge Tekniska Högskola.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A district heating system consists of one or more production units supplying energy in the form of heated water through a distribution pipe network to a multitude of consumers. District heating systems come in a range of different forms and sizes; from small independent systems within industrial estates or university campuses to large city-wide systems supplying millions of consumers with heating and hot water.

  3. 3. High frequency electronic packaging : SBU-materials, material characterization, simulation and processing

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Christian Johansson; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

    Sammanfattning : Electronic packaging continues to move towards improved performance and lower cost. Requirements of higher performance, reduced size, weight and cost of both High Density Interconnects (HDI) and high frequency (HF) devices has led to the search for new: materials, material combinations, methods, processes and production equipment.

  5. 5. Interaction Between Microgels and Oppositely Charged Proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christian Johansson; Uppsala universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microgel; protein; uptake; distribution; core-shell; colloidal stability; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.
