  1. 21. Modeling, Implementation and Evaluation of IP Network Bandwidth Measurement Methods

    Författare :Andreas Johnsson; Mats Björkman; Bob Melander; Gábor Vattay; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer networks; Bandwidth measurement; Wireless networks; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Internet has gained much popularity among the public since the mid 1990's and is now an integrated part of our society. A large range of high-speedbroadband providers and the development of new and more efficient Internet applications increase the possibilities to watch movies and live TV, use IP-telephony and share files over the Internet.

  3. 22. Price measurement and index construction : some contributions to theory and application

    Författare :Jörgen Dalén; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Konsumentprisindex;

    Sammanfattning : Four different problems are treated, all concerned with problems arising when compiling price indexes in official statistics. One deals with the computation of so called elementary aggregates, low level indexes for single products, when proper weights for the observations are not available. LÄS MER

  4. 23. Characterization and Classification of Internet Backbone Traffic

    Författare :Wolfgang John; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Characterization; Measurement; Backbone; Internet; Classification; Traffic; Passive;

    Sammanfattning : We contribute to an improved understanding of Internet traffic characteristics by measuring and analyzing modern Internet backbone data. We start the thesis with an overview of several important considerations for passive Internet traffic collection on large-scale network links. LÄS MER

  5. 24. Solid-State Nanopores for Sensing : From Theory to Applications

    Författare :Chenyu Wen; Shi-Li Zhang; Zhen Zhang; Ulrich F. Keyser; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solid-state nanopore; ionic current; current blockage; effective transport length; noise; surface charge; translocation; biomolecule; electroosmotic flow; vortex; autogenic translocation; multiple nanopores; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Nanopore based sensing technology has been widely studied for a broad range of applications including DNA sequencing, protein profiling, metabolite molecules, and ions detection. The nanopore technology offers an unprecedented technological solution to meeting the demands of precision medicine on rapid, in-field, and low-cost biomolecule analysis. LÄS MER

  7. 25. Non-image-forming effects of light : Implications for the design of living and working environments

    Författare :Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

    Sammanfattning : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. LÄS MER
