  1. 11. Security of Electricity Supply in Power Distribution System : Optimization Algorithms for Reliability Centered Distribution System Planning

    Författare :Sanja Duvnjak Zarkovic; Patrik Hilber; Ebrahim Shayesteh; George Anders; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The importance of electricity in everyday life and demands to improve the reliability of distribution systems force utilities to operate and plan their networks in a more secure and economical manner. With higher demands on reliability from both customers and regulators, a big pressure has been put on the security of electricity supply which is considered as a fundamental requirement for modern societies.

  2. 12. Lignocellulosic Ethanol Production Potential and Regional Transportation Fuel Demand

    Författare :Lilia Daianova; Jinyue Yan; Louise Trygg; Mälardalens högskola; []
    Nyckelord :Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. LÄS MER

  3. 13. System Interconnection Design Trade-offs in Three-Dimensional (3-D) Integrated Circuits

    Författare :Roshan Weerasekera; Hannu Tenhunen; Li-Rong Zheng; Atila Alvandpour; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interconnects; Parasitic Extraction; Repeaters; Signal Integrity; System-on-Chip SoP ; System-in-Package SiP ; System-on-Package SoP ; Three-dimensional 3-D Integration; Through-Silicon-Via TSV ; Vertical Integration; Information technology; Informationsteknik;

    Sammanfattning : Continued technology scaling together with the integration of disparate technologies in a single chip means that device performance continues to outstrip interconnect and packaging capabilities, and hence there exist many difficult engineering challenges, most notably in power management, noise isolation, and intra and inter-chip communication. Significant research effort spanning many decades has been expended on traditional VLSI integration technologies, encompassing process, circuit and architectural issues to tackle these problems.

  4. 14. Reduction of Substrate Noise in Mixed-Signal Circuits

    Författare :Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Sammanfattning : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. LÄS MER

  5. 15. Convergence in mixed reality-virtuality environments : facilitating natural user behavior

    Författare :Daniel Johansson; Leo J. de Vin; Morten Fjeld; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mixed reality. augmented reality; augmented virtuality; head mounted display; omnidirectional floor; natural interface; telepresence; Datalogi; Computer and Systems Science;

    Sammanfattning : This thesis addresses the subject of converging real and virtual environments to a combined entity that can facilitate physiologically complying interfaces for the purpose of training. Based on the mobility and physiological demands of dismounted soldiers, the base assumption is that greater immersion means better learning and potentially higher training transfer. LÄS MER
