Abstract:

To be able to do the correct action when a fault is detected, the fault isolation part must be precise and run in real time during operation of the process. In many cases can it be difficult to decide exactly where the fault is localized. In those cases, the isolation algorithm must rank the faults according to their probability to be the cause to the behavior. The masters thesis project aims at probabilistic methods and algorithms for fault isolation in embedded systems. Different kind of Bayesian Networks have been compared in this report and the comparison has been done on a literature defi

Abstract:

The aim of this thesis is to contribute to improved diagnosis of automotive vehicles. The work is driven by case studies, where problems and challenges are identified. To solve these problems, theoretically sound and general methods are developed. The methods are then applied to the real world systems. To fulfill performance requirements automotive vehicles are becoming increasingly complex products. This makes them more difficult to diagnose. At the same time, the requirements on the diagnosis itself are steadily increasing. Environmental legislation requires that smaller deviations from spec

In this work, a new boundary element method is presented for the Probabilistic Fracture Mechanics analysis. The method developed allows the probabilistic analysis of cracked structure accomplished by the dual boundary element method (DBEM), in which the traction integral equation is used on one of the crack faces as opposed to the usual displacement integral equation. The stress intensity factors and their first order derivatives are evaluated for mode-I and mixed-mode fracture problems.

This thesis begins by noting that the current safety justification of pressurised water reactor pressure vessels is deterministic. To enable probabilistic structural integrity safety cases of reactor pressure vessels to be carried out, a need for a new analysis of the statistical properties of fracture toughness is identified. Fracture is linked to the cracking of critically sized carbide, and a preliminary analysis showed that the distribution of carbide in steel could be described by an exponential distribution. Initially the failure of an individual fracture toughness test specimen is consi

Abstract:

Weight growth has been a significant factor in nearly every space and launch vehicle development program. In order to account for weight growth, program managers allocate a design margin. However, methods of estimating design margin are not well suited for the task of assigning a design margin for a novel concept. In order to address this problem, a hybrid method of estimating margin is developed. This hybrid method utilizes range estimating, a well-developed method for conducting a bottom-up weight analysis, and a new forecasting technique known as executable morphological analysis.

The advent of deregulated electricity and the call for sustainable energy practices are major drivers for the continued increase of renewable energy systems within the modern day power network.

This increases the level of uncertainty witnessed within the power system as such, as the penetration of renewable energy systems continue to increase, their effects cannot be trivialised.

A study of feasibility is performed for the development of a nowcasting method of aircraft icing conditions. The supercooled cloud water content is a key parameter for the determination of hazardous regions. The production of supercooled water in clouds is possible only where sufficiently strong updraft produces supersaturation with respect to water. However, to maintain the presence of supercooled droplets, the generation of moisture excess during the air uplift must exceed the rate of vapor deposition on snow and the rate of snow riming.

Probabilistic models and fuzzy set models describe different aspects of uncertainty. Probabilistic models primarily describe random variability in parameters. In engineering system safety, examples are variability in material properties, geometrical dimensions, or wind loads. In contrast, fuzzy set models of uncertainty primarily describe vagueness, such as vagueness in the definition of safety. When there is only limited information about variability, it is possible to use probabilistic models by making suitable assumptions on the statistics of the variability. However, it has been re

Abstract:

Probabilistic seismic assessment is of interest both in the design of new structures, and in the assessment of existing structures. An accurate prediction of the structural response distribution requires a large number of dynamic analyses, using a large number of ground motions. Such a task, however, requires substantial computational work, and, furthermore, is impeded by the scarcity of high intensity records. In this research a methodology is proposed for sampling optimized suites of ground motions, which methodology is comprised of a vector-valued intensity measure (IM), and a ground motion
