  1. 6. Advances in High Porductivity - High Quality Machining

    Författare :Marcel Escursell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; Quality; Machining; Productivity;

    Sammanfattning : Quality, productivity and flexibility are vital factors in todays machining industry in order to remain competitive. Nowadays, finished products not only have to be produced within specific tolerance limits, but they also have to posses high standards in terms of surface integrity, i.e. LÄS MER

  3. 7. Optimization of track geometry maintenance : a study of track geometry degradation to specify optimal inspection intervals

    Författare :Iman Arasteh khouy; Per-Olof Larsson-Kråik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Railway infrastructure is a complex system which comprises different subsystems. Long useful life span is one of the important aspects of this prime mode of transport. The useful life length of its assets is highly dependent on the maintenance and renewal strategy used during its life cycle. LÄS MER

    Sammanfattning : Mobile video content today generates more than half of the mobile data traffic.The increasing popularity of mobile video on demand services poses great challenges to mobile operators and content providers. LÄS MER

  5. 9. Distributed Multiple Access and Service Differentiation Algorithms for Wireless Networks

    Författare :Thomas Nilsson; Per-Åke Wedin; Jerry Eriksson; Lennart Bondesson; Andrzej Duda; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Local Area Networks; Medium Access Control; Quality of Service; Resource Allocation; IEEE 802.11; IEEE 802.11e; Datatransmission; Datatransmission;

    Sammanfattning : Communicating over a wireless channel poses many unique challenges not found in wired communication because of the special characteristics of the wireless channel. The capacity in a wireless network is typically scarce as a result of the limited bandwidth and many distinct phenomenons, like attenuation and interference, that work destructively on the received signals.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

    Sammanfattning : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. LÄS MER
