2. 1. Some Problems in Quantified Security

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

   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

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

   Author : Johan Setréus; Lina Bertling; Roland Eriksson; Stefan Arnborg; Lars Wredenberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; Electric power engineering; 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

5. 3. Leaf- to field-level compound effects of warm and dry conditions on crops and potential mitigating strategies

   Author : Xiangyu Luan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Ongoing climate change has been threatening global food security. Under climate change, increasing risk of hot and dry conditions (termed compound events) is projected in many agricultural regions. Compound events cause detrimental effects on crops, yet their effects have rarely been quantified based on modeling approach. READ MORE

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

   Author : Kun Zhu; Lars Nordström; Boming Zhang; KTH; []
   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.

7. 5. Assessment of Telematic Systems for Road Freight Transport

   Author : Gideon Mbiydzenyuy; []
   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
