3. 2. Regional and Industrial Co-operation in District Heating Systems

   Författare :Alemayehu Gebremedhin; Thore Berntsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A century after the introduction of the first district heating system (DHS) on a commercial basis, the technology has still not become as widespread as it deserves to be. The role of district heating (DH) has meant not only comfort for its users but also less impact on the environment. LÄS MER

4. 3. The impact of a widened energy system boundary on cost effectiveness

   Författare :Alemayehu Gebremedhin; Olof Björkqvist; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This study describes the impact of widened system boundaries in the choice of heat generating plants, the total cost of the defined energy system and the use of combined heat and power (CHP) production plants. The economic and environmental benefits of co­ operation between public utilities and industries and the importance of enlarged system boundaries are shown in the different case-studies. LÄS MER

5. 4. Automatic and Explicit Parallelization Approaches for Equation Based Mathematical Modeling and Simulation

   Författare :Mahder Gebremedhin; Peter Fritzson; Erwin Laure; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Modelling; Simulation; Multi-core; Automatic Parallelization; Clustering; Scheduling; Explicit Parallelization; ParModelica; Task Systems; GPGPU;

   Sammanfattning : The move from single-core processor systems to multi-core and manyprocessor systems comes with the requirement of implementing computations in a way that can utilize these multiple computational units efficiently. This task of writing efficient parallel algorithms will not be possible without improving programming languages and compilers to provide the supporting mechanisms. LÄS MER

7. 5. Automatic and Explicit Parallelization Approaches for Mathematical Simulation Models

   Författare :Mahder Gebremedhin; Peter Fritzson; Francesco Casella; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation; Modelling; Parallel Programming; Mutli-core; Modelcia; OpenModelica; ParModelica;

   Sammanfattning : The move from single core and processor systems to multi-core and many-processors systemscomes with the requirement of implementing computations in a way that can utilizethese multiple units eciently. This task of writing ecient multi-threaded algorithmswill not be possible with out improving programming languages and compilers to providethe mechanisms to do so. LÄS MER
