Abstract:

EDF Energy own and operate seven Advanced Gas cooled Reactor (AGR) nuclear power plants which are the only commercially operated high temperature nuclear reactors in the world. Being high temperature means that considerable numbers of components operate within the creep regime and as a result, creep-fatigue is a life limiting degradation mechanism for many reactor components. Nuclear safety is the overriding priority for the operator, EDF Energy. Therefore demonstrating the integrity of structural components is an important activity. This poses the greatest challenge for components within the

Abstract:

In 1996, a concept was proposed by the UK Ministry of Defence with the intention of making the field of reliability more useful to the end user, particularly within the field of military aerospace. This idea was the Maintenance Free Operating Period (MFOP), a duration of time in which the overall system can complete all of its required missions without the need to undergo emergency repairs or maintenance, with a defined probability of success. The system can encounter component or subsystem failures, but these must be carried with no effect to the overall mission, until such time as repair tak

Abstract:

Device drivers are Operating Systems (OS) extensions that enable the use of I/O devices in computing systems. However, studies have identified drivers as an Achilles’ heel of system reliability, their high fault rate accounting for a significant portion of system failures. Consequently, significant effort has been directed towards improving system robustness by protecting system components (e.g., OS kernel, I/O devices, etc.) from the harmful effects of driver faults. In contrast to prior techniques which focused on preventing unsafe driver interactions (e.g., with the OS kernel), my thesis is

Abstract:

Lifelines provide the vital utilities for human being in the modern life. They convey a great variety of products in order to meet the general needs. Also, buried continuous pipelines are generally used to transmit energy sources, such as natural gas and crude oil, from production sources to target places. To be able to sustain this energy corridor efficiently and safely, interruption of the flow should be prevented as much as possible. This can be achieved providing target reliability index standing for the desired level of performance and reliability. For natural gas transmission, assessment

We present the Hadley model, a formal descriptive model of input and output for modern computer operating systems.

To illustrate an initial application domain, we discuss the utility of the Hadley model and a potential associated I/O system as a tool for digital forensic investigators. To illustrate practical uses of the Hadley model we present the Hadley Specification Language, an

A stable and reliable electrical power supply system is an inevitable pre-requisite for the technological and economic growth of any nation.

It is known fact around the world that 90% of the customer service interruptions are caused due to failure in distribution system. Therefore, it is worth considering reliability assessments as it provides an opportunity to incorporate the cost or losses incurred by the utilities

Abstract:

Computing the reliability of a network is a #P-complete problem, therefore estimation by means of simulation often becomes a favourable choice. In modern communication networks, link failure probabilities are usually small and hence network failures become rare events. This poses a challenge to estimate the network reliability. In this thesis we present different techniques for network reliability estimation. There are two main sampling techniques in reliability estimation: combinatorial and permutational sampling. Combinatorial sampling has the advantage of speed but has poor performance in r

The ability to estimate the asset reliability and the probability of failure is critical to reducing maintenance costs, operation downtime, and safety hazards.

Abstract:

Power companies around the world are incorporating wind power into their electricity networks. Wind power is an intermittent source of energy and its technical and financial impacts on the transmission and distribution networks are not yet totally investigated. This thesis investigates the impact of wind power on power system reliability evaluation. The investigation includes long-term system planning and short-term operational planning on reliability evaluation taking into accounts different penetration levels of wind power. This thesis presents a Wind-Hydro Cooperation (WHC) method for reduc
