  1. 1. On Connection Admission Control in Computer Networks

    Författare :Stanislav Belenki; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quality of service; packet-switched networks; the Internet; admission control;

    Sammanfattning : The best-effort nature of the Internet is a result of a relative simplicity of the network. This nature also allows the Internet to achieve high utilization of its resources. However, all these benefits are traded for inability of the Internet to provide a guaranteed or predictive quality of service (QoS). LÄS MER

  3. 2. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

    Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

  4. 3. A perfect score : Validity arguments for college admission tests

    Författare :Per-Erik Lyrén; Christina Stage; Marie Wiberg; Simon Wolming; Stephen G. Sireci; Umeå universitet; []
    Nyckelord :college admission tests; SweSAT; validity; interpretive arguments; predictive validity; equating; item revisions; subscores;

    Sammanfattning : College admission tests are of great importance for admissions systems in general and for candidates in particular. The SweSAT (Högskoleprovet in Swedish) has been used for college admission in Sweden for more than 30 years, and today it is alongside with the upper-secondary school GPA the most widely used instrument for selection of college applicants.
