  2. 11. Multilevel three-phase dual active bridge dc-dc converters - A study on converter modulation, capacitive energy requirement, ZVS boundaries, MFT's winding connections, and core losses

    Author : Babak Alikhanzadehalamdari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-voltage power converters; dual active bridge; harmonic analysis; three-phase system; medium-frequency transformer; capacitor sizing; multilevel converters; high power-density systems; transformer winding connection; core loss modeling; dc collector network; soft-switching converters;

    Abstract : The collection and transmission of power from offshore wind turbines using dc have advantages over the ac system. One of the enabling technologies for deploying dc collection is the dc-dc converter that boosts the dc output from the turbine to the medium-voltage dc level of the collection grid. READ MORE

  4. 12. Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

    Author : Danfeng Cao; Edwin Jager; Jose Gabriel Martinez Gil; Jonathan Rossiter; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The human body is a complex system, consisting of different types of biomolecules and living matters, such as nucleic acids, proteins, carbohydrates, lipids, serum, cells, tissues, and organs. These complex biomolecules and living matters integrate and interact dynamically to perform and maintain body functions. READ MORE

  5. 13. Mapping Concurrent Applications to Multiprocessor Systems with Multithreaded Processors and Network on Chip-Based Interconnections

    Author : Ruxandra Pop; Petru Eles; Shashi Kumar; Linköpings universitet; []
    Keywords : Network on Chip; Multiprocessor Embedded Systems; Task Mapping; Task Scheduling; Multithreading; Simultaneous Multithreading; Response Time Estimation; Genetic Algorithms; List Scheduling; Soft Deadline; Task Graphs; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Network on Chip (NoC) architectures provide scalable platforms for designing Systems on Chip (SoC) with large number of cores. Developing products and applications using an NoC architecture offers many challenges and opportunities. A tool which can map an application or a set of applications to a given NoC architecture will be essential. READ MORE

  6. 14. High Speed (MHz) Switch Mode Power Supplies (SMPS) using Coreless PCB Transformer Technology

    Author : Hari Babu Kotte; kent Bertilsson; Bengt Oelmann; Per Karlsson; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SMPS; High Frequency converters; Coreless PCB transformers; Electrical engineering; Elektroteknik; Electronics; Elektronik;

    Abstract : The most essential unit required for all the electronic devices is the Power Supply Unit (PSU). The main objective of power supply designers is to reduce the size, cost and weight, and to increase the power density of the converter. READ MORE

  7. 15. On technologies for ubiquitous multimedia communication

    Author : Johan Kristiansson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Abstract : The proliferation of multimedia and deployment of wireless networks over the last decade have made it possible for users to communicate and share information using e-meeting services from almost any location at anytime. While these new services offer new ways to communicate, they are not always easy to use because of the heterogeneity of networks and devices, which must be managed by the users to take full advantage of the possible benefits.
