4. 23. Size Estimation of Real-Time Software Components - A System Perspective

   Författare :Kenneth Lind; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; COSMIC Function Points; software code size; Functional Size Measurement; software components; system architecture.;

   Sammanfattning : The demands and expectations on the system architectures of contemporary consumer products like cars are increasing for each product generation. New features using new sensors and actuators, with different variants on different markets, and that interact with other features, create additional complexity in the system. LÄS MER

5. 24. Excited State Processes in Solar Energy Materials

   Författare :Tomas Österman; Kemisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solar cells; Conjugated polymers; Charge transfer state; Time-resolved spectroscopy; Fluorescence; Artificial Photosynthesis; Bis-tridentate ruthenium II -complexes; Density functional theory; Quantum chemistry.;

   Sammanfattning : This dissertation covers studies of excited state processes in two types of solar energy materials: alternating polyfluorene polymers and their blends with fullerenes in the active layer of plastic solar cells, and bis-tridentate RuII-polypyridyl complexes to be used as sensitizer in systems for artificial photosynthesis. The polymer:fullerene blends were studied by transient absorption and time-resolved fluorescence measurements in order to investigate the role of the charge transfer (CT) state in charge formation.

7. 25. Theoretical Routes for c-BN Thin Film Growth

   Författare :Johan Karlsson; Karin Larsson; Sven Ulrich; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cubic boron nitride; chemical vapor deposition; density functional theory; adsorption; abstraction; Inorganic Chemistry; Oorganisk kemi;

   Sammanfattning : c-BN has been in focus for several years due to its interesting properties. The possibility for large area CVD is a requirement for the realization of these different properties in various applications. Unfortunately, there are at present severe problems in the CVD growth of c-BN. LÄS MER
