  1. 1. Some Problems in Quantified Security

    Author : Vilhelm Verendel; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; risk behavior; quantified security; risk perception; security metrics; computer security; survey; decision-making; operational risk; quantified risk; quantitative models; information security;

    Abstract : This thesis contains work related to quantitative representation and analysis of computer and information security. The ability to accurately describe security using quantitative methods could offer better control and evaluation of security in operational settings. READ MORE

  2. 2. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

    University dissertation from Stockholm : KTH

    Author : Johan Setréus; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Abstract : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. READ MORE

  3. 3. Assessment of Telematic Systems for Road Freight Transport

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Gideon Mbiydzenyuy; Blekinge Tekniska Högskola.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transportation; telematics; architectures; analysis; optimization; clustering; net present value;

    Abstract : The focus of this thesis is the assessment of telematic systems for road freight transport from a planning perspective. The aim is to support strategic decisions related to architectural choices for such systems, with the possibility to achieve synergies by supporting multiple telematic services. READ MORE

  4. 4. Data Quality in Wide-Area Monitoring and Control Systems PMU Data Latency, Completness, and Design of Wide-Area Damping Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Kun Zhu; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phasor Measurement Units; Wide-Area Monitoring and Control systems; latency; completeness; power system communication; simulation; empirical study;

    Abstract : The strain on modern electrical power system operation has led to an ever increasing utilization of new Information Communication Technology (ICT) systems to enhance the reliability and efficiency of grid operation. Among these proposals, Phasor Measurement Unit (PMU)-based Wide-Area Monitoring and Control (WAMC) systems have been recognized as one of the enablers of “Smart Grid”, particularly at the transmission level, due to their capability to improve the real-time situational awareness of the grid.
