  1. 1. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

    Författare :Sofia Berg; Tomas Jonsson; Bo Ebenman; Daniel Stouffer; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. LÄS MER

  3. 2. Selected Problems in Financial Mathematics

    Författare :Erik Ekström; Johan Tysk; Svante Janson; Lane P. Hughston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; American options; convexity; monotonicity in the volatility; robustness; optimal stopping; parabolic equations; free boundary problems; volatility; Russian options; game options; excessive functions; superreplication; smooth fit; Matematisk analys; Mathematical analysis; Analys;

    Sammanfattning : This thesis, consisting of six papers and a summary, studies the area of continuous time financial mathematics. A unifying theme for many of the problems studied is the implications of possible mis-specifications of models. Intimately connected with this question is, perhaps surprisingly, convexity properties of option prices. LÄS MER

  4. 3. Track circuits’ robustness : Modeling, measurement and simulation

    Författare :Emilio Rodriguez; Ajit Kumar Verma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Track circuit; Relay; False positive signals; Signalling in railway; Modelling; Simulation; Testing; Robustness; Interoperability; Reliability; Railway Infrastructure; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In countries with rough weather conditions, frequent delays cause railway companies to waste time and money. Many of these delays are related to the train detection systems, as the old DC track circuits are still used in some countries, including Sweden, our case study. LÄS MER

  5. 4. Topics in Robustness Analysis

    Författare :Sina Khoshfetrat Pakazad; Anders Hansson; Torkel Glad; Anders Helmersson; Bo Bernhardsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In this thesis, we investigate two problems in robustness analysis of uncertain systems with structured uncertainty. The first problem concerns the robust finite frequency range H2 analysis of such systems. LÄS MER

  7. 5. Software Robustness: From Requirements to Verification

    Författare :Ali Shahrokni; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robustness; quality requirements; requirements patterns; robustness testing; requirements specification; non-functional requirements; requirements refinement;

    Sammanfattning : The importance of software quality increases as software products become more intertwined with our everyday lives. A critical software quality attribute is robustness, i.e. that the software shows stable behavior in stressful conditions and when receiving faulty inputs. LÄS MER
