  1. 11. A Non-Gaussian Limit Process with Long-Range Dependence

    Författare :Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. LÄS MER

  3. 12. Reliable and deterministic network services

    Författare :Florian-Daniel Otel; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

    Sammanfattning : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. LÄS MER

  4. 13. The arrival of the tipping point of solar photovoltaic technology

    Författare :Ying Yang; Jinyue Yan; Reinhard Madlener; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Sammanfattning : Solar photovoltaic (PV) technology has become well-established for addressing both greenhouse gas emission reductions and regional air pollution. Rapid developments within the solar PV sector are still facing various technical barriers, economic impediments, and institutional barriers. LÄS MER

  5. 14. Various aspects of treatment in cardiac arrest prior to hospital arrival

    Författare :Per Nordberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :out-of-hospital cardiac arrest;

    Sammanfattning : Background and aims: Out-of-hospital cardiac arrest (OHCA) is a major public health issue, affecting almost 300,000 victims per year in Europe, who have an overall survival rate of about 10 per cent. In general, the current Emergency Medical Services (EMS) do not have the capacity to act quickly and effectively enough in regard to this vast group of patients. LÄS MER
