  1. 1. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  3. 2. Models and Complexity Results in Real-Time Scheduling Theory

    Författare :Pontus Ekberg; Wang Yi; Alberto Marchetti-Spaccamela; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; Scheduling theory; Task models; Computational complexity; Datavetenskap med inriktning mot inbyggda system; Computer Science with specialization in Embedded Systems;

    Sammanfattning : When designing real-time systems, we want to prove that they will satisfy given timing constraints at run time. The main objective of real-time scheduling theory is to analyze properties of mathematical models that capture the temporal behaviors of such systems. LÄS MER

  4. 3. Transformation of component models to real-time models

    Författare :Johan Fredriksson; Martin Törngren; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Industry is constantly looking for new developments in software for use in increasingly complex computer applications. Today, the development of component-based systems is an attractive area for both Industry and Academia. The systems we focus on in this thesis are embedded computers, in particular those in automotive systems. LÄS MER

  5. 4. Real-Time Optimization of Cone Crushers

    Författare :Erik Hulthén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process optimization; crushing; CSS; real-time optimization; eccentric speed; cone crusher;

    Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. LÄS MER

  7. 5. Improving strategic decisions for real estate investors : Perspectives on allocation and management

    Författare :Sigrid Katzler; Svante Mandell; Inga-Lill Söderberg; Elias Oikarinen; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public real estate; private real estate; MPT; time-varying correlation; liquidity; mixed-asset portfolio; real estate portfolio; diversification; outsourcing; Fastigheter och byggande; Real Estate and Construction Management;

    Sammanfattning : Real estate is an attractive asset class in the mixed-asset portfolio due to favorable risk return characteristics and low correlations with other asset classes like stock and bonds. Unlike financial assets, real estate is a physical asset where large lot sizes/indivisibility, heterogeneity, low liquidity and high transaction costs make applying financial models like modern portfolio theory (MPT) challenging.
