    Sammanfattning : The mobile industry is preparing to scale up the network capacity by a factor of 1000x in order to cope with the staggering growth in mobile traffic. As a consequence, there is a tremendous pressure on the network infrastructure, where more cost-effective, flexible, high speed connectivity solutions are being sought for. LÄS MER

  2. 2. Security and Risk Assessment: Black box modeling, Taxonomy and Systematic Literature Review

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Laleh Pirzadeh Irannezhad; [2016]

    Sammanfattning : In order to successfully perform and manage any type of project, there is a need to identify and assess the key factors that have an effect on the project's performance and its deliverables. Security and risk are two important concepts in contemporary information system industry that need to be assessed and addressed. LÄS MER

    Sammanfattning : Ubiquitous deployment of embedded systems is having a substantial impact on our society, since they interact with our lives in many critical real-time applications. Typically, embedded systems used in safety or mission critical applications (e.g. LÄS MER

  4. 4. Broadening Horizons The FMECA-NETEP model, offshore wind farms and the permit application process

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :John Ohlson; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cumulative impact; risk; offshore wind farm OWF ; FMECA; kumulativa effekter; risk; havsbaserad vindkraft; Miljövetenskap; Environmental Science;

    Sammanfattning : Abstract  The permit application process for offshore wind farms (OWF) in Sweden conceivably requires a comprehensive and transparent complement within risk management. The NETEP framework (covering risks concerning navigation, economics, technology, environment and politics), based on a futures planning mechanism (STEEP) has consequently been brought forward as a structure for the application of FMECA (Failure Mode, Effects, and Criticality Analysis) methodology to the permit application process of the Swedish offshore wind farm sector.

  5. 5. IT Dependability Management in Governmental Organisations

    Detta är en avhandling från Department of Computer Science, Lund University

    Författare :Kim Weyns; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT management; Risk management; Information safety; Emergency management; Maturity models; Software reliability modelling; Service level agreements;

    Sammanfattning : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. This is especially true for systems that are critical in a crisis situation and whose dependability is an important factor in an organisation's capability to resolve a crisis. LÄS MER
