  1. 21. QoS Control of Real-Time Data Services under Uncertain Workload

    Författare :Mehdi Amirijoo; Jörgen Hansson; Sang Son; Svante Gunnarsson; Joseph Hellerstein; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time system; database; feedback control; Computer science; Datavetenskap;

    Sammanfattning : Real-time systems comprise computers that must generate correct results in a timely manner. This involves a wide spectrum of computing systems found in our everyday life ranging from computers in rockets to our mobile phones. The criticality of producing timely results defines the different types of realtime systems. LÄS MER

  3. 22. Modeling pooling and perishable items in inventory systems

    Författare :Patrik Tydesjö; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; two level; perishable items; Inventory control; newsboy model; emergency supply; stochastic; lateral transshipments; upstream customer demand.;

    Sammanfattning : This thesis is built on three papers considering different problems in inventory control. The first paper considers a two-location newsboy model with the possibility of making lateral transshipments when needed. Usually, when considering newsboy models it is assumed that all demand in a period occurs at once. LÄS MER

  4. 23. Dynamic Modelling of Transit Operations and Passenger Decisions

    Författare :Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

    Sammanfattning : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. LÄS MER

  5. 24. Automatic memory management for flexible real-time systems

    Författare :Sven Robertz; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; feedback scheduling; embedded systems; real-time; memory management; garbage collection; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. LÄS MER

  7. 25. Planering eller frigörelse? : En studie om bemyndigande

    Författare :Sven Jarhag; Socialhögskolan; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Care and help to handicapped; Sociology; Control; Liberation Emancipation; Functional Impairments; Empowerment; Planning; Social law; vård och rehabilitering; Handikappade; Sociologi; Socialrätt;

    Sammanfattning : The legislation on rights that was presented in the final report of the commission of inquiry into handicap (SOU 1991:46), the Act concerning Support and Service for Persons with Certain Functional Impairments, showed that, from an ethical point of view, society´s welfare is something that concerns everyone. The demand for social solidarity, according to the inquiry, meant that public measures must be designed to meet quality requirements aiming at self-determination and influence, accessibility, participation, and continuity and holism.
