  1. 1. On Intelligent District Heating

    Author : Christian Johansson; Blekinge Tekniska Högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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

    Author : Christian Johansson; Blekinge Tekniska Högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.

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

    Author : Christian Johansson; Hjalmar Hesselbom; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; dielectric loss; high frequency electrical characterization; microwave circuits; multilayer thin film technology; ORMOCER; permittivity; sequential build up; silicone elastomer;

    Abstract : 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.
