  2. 21. Autonomous Power Systems based on Renewables - On generation reliability and system control

    Author : Jimmy Ehnberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Today one billion people are living in non-electrified areas. A majority of the people are living in rural areas in developing countries where there are no possibilities, neither economical nor technical, for grid extension. Instead energy sources like wood and fossil fuels are used. READ MORE

  4. 22. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance

    Author : Tommie Lindquist; Prof. Roland Eriksson; Dr. Lina Bertling; Docent Carl-Ejnar Sölver; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Maintenance; reliability modelling; electrical power systems; ageing; failure mechanisms; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Abstract : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. READ MORE

  5. 23. Reliability, replicability and reproducibility in PET imaging

    Author : Granville James Matheson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Positron Emission Tomography (PET) is a non-invasive biomedical imaging method which can quantify biochemical markers as well as functional and metabolic activity in vivo. Following image analysis, quantification can be performed using various pharmacokinetic models, or using simplified semi-quantitative methods. READ MORE

  6. 24. Optical Interconnects for Next Generation Data Centers : Architecture Design and Resource Allocation

    Author : Yuxin Cheng; Jiajia Chen; Lena Wosinska; Po Dong; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The current data center architectures based on blade servers and elec- tronic packet switches face several problems, e.g., limited resource utilization, high power consumption and cost, when handling the rapidly growing of data traffic. READ MORE

  7. 25. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation

    Author : Andreas Jamnig; Kostas Sarakinos; Gregory Abadias; Gregory Thompson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

    Abstract : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. READ MORE
