  1. 21. Quantitative 3D reconstruction of porous polymers using FIB-SEM tomography -correlating materials structures to properties of coatings for controlled drug release

    Författare :Cecilia Fager; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tomography; controlled drug release; 3D; connectivity; insulating material; polymer film; soft material; focused ion beam; scanning electron microscopy;

    Sammanfattning : Porous networks are found in a wide range of different advanced and technologically important materials and influence the materials properties. The networks are active components in for example batteries, food and pharmaceuticals. The interconnectivity of a network strongly influences the transport properties. LÄS MER

  3. 22. Crosstalk in Wideband Wireline Systems -- Curse and Blessing

    Författare :Yezi Huang; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The fourth generation broadband (4GBB) concept aims for ubiquitous and high-speed data communication over the existing twisted copper pairs between the last distribution point and the customer premise equipment. Although it saves deployment cost for the last-mile communication, using the existing copper infrastructure makes the system vulnerable to crosstalk due to electro-magnetic coupling from the neighboring pairs.

  4. 23. Aggregation of Plug-in Electric Vehicles in Power Systems for Primary Frequency Control

    Författare :Seyedmahdi Izadkhast; Mehrdad Ghandhari; Garcia-Gonzalez Pablo; Frias Pablo; Ignacio Egido Cortés; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aggregation; Plug-in Electric Vehicles; Primary Frequency Control; Aggregeren; Plug-in Elektrische Voertuigen; Primaire Reserve; Laddbara Bilar; Elnätet; Primär Frekvensreglering; Agregación; Vehículos Eléctricos Enchufables PEVs ; Control Primario de Frecuencia PFC ; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The number of plug-in electric vehicles (PEVs) is likely to increase in the near future and these vehicles will probably be connected to the electric grid most of the day time. PEVs are interesting options to provide a wide variety of services such as primary frequency control (PFC), because they are able to quickly control their active power using electronic power converters.

  5. 24. Stereoscopic 3D Video Quality of Experience : impact of coding, transmission and display technologies

    Författare :Kun Wang; Mårten Sjöström; Kjell Brunnström; Ulf Jennehag; Roger Olsson; Hans-Jürgen Zepernick; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Three-Dimensional (3D) videos are using their success from cinema to home entertainmentmarkets such as TV, DVD, Blu-ray, video games, etc. The video quality isa key factor which decides the success and acceptance of a new service. Visual qualitywill have more severe consequences for 3D than for 2D videos, e.g. LÄS MER

  7. 25. Born Globals : Rapid International Growth in New Ventures

    Författare :Ingemar Wictor; Svante Andersson; Tomas Müllern; Sören Sören Kock; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Born Global; internationalisation; entrepreneur; network; vision; value chain; growth; management; leadership; entrepreneurial teams;

    Sammanfattning : The traditional theories developed by Johanson and Vahlne (1977, 1990) and other researchers ofinternationalisation have long been questioned because of the fast-changing environment and deregulations. In particular, for Born Global firms, namely a company that has achieved a foreign sales volume of at least 25% within three years of its inception and that seeks to derive significant competitive advantage from the use of resources and the sales of outputs in multiple countries (Andersson and Wictor, 2003, p.
