  1. 1. On-demand Restricted Delegation : A Framework for Dynamic, Context-Aware, Least-Privilege Delegation in Grids

    Författare :Mehran Ahsant; Lennart Johnsson; Marty Humphrey; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grid Security; Restricted and Context-Aware Delegation; Delegation Protocol; On-demand Delegation; Dynamic Trust Federation; Grid Interoperability; Credential Mapping; Computer science; Datalogi;

    Sammanfattning : In grids, delegation is a key facility that can be used to authenticate and authorize requests on behalf of disconnected users. In current grid systems,delegation is either performed dynamically, in an unrestricted manner, or by a secure but static method. LÄS MER

  3. 2. Visual demand in manual task performance - Towards a virtual evaluation

    Författare :Tania Dukic; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; working posture; computer manikin software; motion; visual demand;

    Sammanfattning : Visual information is crucial for carrying out motor activities. However, knowledgeabout the effects of visual demand on the performance of manual tasks is not welldocumented. Visual determinants must be identified in order to be used in visualisationand simulation tools (e.g. LÄS MER

  4. 3. Evaluation of forecasting techniques and forecast errors : with focus on intermittent demand

    Författare :Peter Wallström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : To decide in advance the amount of resources that is required next week or next month can be both a complicated and hazardous task depending on the situation, despite the known time frame when the resources are needed. Intermittent demand, or slow-moving demand, that is when there are time periods without demand and then suddenly a time period with demand, becomes even more difficult to forecast. LÄS MER

  5. 4. Communication technology and travel demand models

    Författare :Maria Börjesson; Infrastruktur KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Travel survey; Transport mode; Telecommuting; Mathematical model; Motivation; 11 Road: Personal transport; 11 Road: Personal transport;

    Sammanfattning : Transportation planners have traditionally focused on physical travel only, and disregarded the fact that other modes of communication may influence travel demand. However, modern telecommunications are rapidly increasing the accessibility to activities that previously only could be reached by physical transportation. LÄS MER

  7. 5. A Division-of-Labor Hypothesis : Adaptations to Task Structure in Multiple-Cue Judgment

    Författare :Linnea Karlsson; Peter Juslin; David Lagnado; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple-cue judgment; exemplar models; cue abstraction; cue-combination rule; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : Judgments that demand consideration of pieces of information in the environment occur repeatedly throughout our lives. One professional example is that of a physician that considers multiple symptoms to make a judgment about a patient’s disease. LÄS MER
