Abstract:

In this thesis a brief history of dynamic pile analysis methods and the associated background theory are presented. In addition an unpublished rigorous mathematic proof of the Case method and new general theoretical model for dynamic pile analysis, developed as the Aberdeen method, are given. The dynamic and static response of model concrete piles in dry sand to impact and static loads have also been investigated experimentally and the results are reported in this thesis. Pile response has been found to be crucially dependent on the damping in the system. The method of modal analysis has been

Abstract:

In a variety of industrial sectors the condition monitoring of induction machines is an important aspect of any condition based maintenance regime. To date, no panoptic means of assessing induction machine health from a single machine parameter exists, further, little work has been performed on the condition monitoring of inverter fed induction machines, an area of increasing importance. In addition, the signal processing tool Higher Order Spectra has been the subject of a great deal of research, and these tools have certain properties which make them ideal for application in a condition monit

Abstract:

The prefailure detection of faults in operating plant can effect major rewards in both safety and economy. A successful on-condition maintenance philosophy would pay great dividends particularly in the offshore oil industry where -until recently, only token methods have been employed. Many techniques are available for monitoring mechanical plant and several of these are considered in general terms. Industrial methods are subsequently evaluated on reciprocating compressor and rolling element bearing faults. Bearing fault analysis is considered in two stages. Initially, a series of vibration bas

Abstract:

The application of Artificial Neural Networks to condition monitoring has been shown to offer substantial rewards, both in improving safety and reducing maintenance costs. However, introducing ANN's to real industrial situations, highlights a need to improve the application of this powerful technology. This thesis attempts to highlight some of the issues associated with applying ANN's, by first considering how to diagnose combinations of faults. It is shown that by applying a modular approach, using one network per fault, a means is available to accommodate combinations of faults, effectively

Abstract:

The unimodality of a function seems a simple concept. But in the Euclidean space R^m, m=3,4,..., it is not easy to define. We have an easy tool to find the minimum point of a unimodal function. The goal of this project is to formalize and support distinctive strategies that typically guarantee convergence. Support is given both by analytic arguments and simulation study. Application is envisioned in low-dimensional but non-trivial problems. The convergence of the proposed iterated grid search algorithm is presented along with the results of particular application studies. It has been recogn

Abstract:

The primary aim of this thesis is to develop a novel procedure for an intelligent automatic diagnostic condition monitoring system for rolling element bearings. The applicability of this procedure is demonstrated by its implementation in a particular electric motor drive system. The novel bearing condition diagnostic procedure developed involves three stages combining the merits of advanced signal processing techniques, feature extraction methods and artificial neural networks. This procedure is the effective combination of these techniques and methods in a holistic approach to the rolling ele

This thesis is concerned with the investigation and development of methods to monitor the condition of electrical machines, with particular reference to induction machines fed from variable frequency, power electronic supplies. A variety of techniques are suggested whereby the faults that most commonly afflict electrical machines can be identified. Techniques involving the detection and analysis of line current, frame vibration, and leakage magnetic field are proposed and developed to take account of the rich spectrum of harmonics that can be injected through the use of power electronic invert

Abstract:

Automated fault diagnosis in induction machines is a difficult task and normally requires background information of electrical machines. Here a different methodology to the condition monitoring problem is devised. The approach is based entirely on Digital Signal Processing (DSP) and Statistical Pattern Recognition (PR). Description of machine conditions is extracted from empirical data. The main tasks that must be carried out by a PR-based condition monitoring system are: condition identification, knowledge reinforcement and knowledge creation for previously unseen conditions.

Abstract:

There is evidence from a number of species that body condition or fatness plays a role in the regulation of energy balance, through a direct effect on voluntary food intake (VFI). However, since differences in body condition are frequently confounded with differences in previous nutrition, this study investigated the role of both factors in the control of VFI in sheep. In ewes grazing autumn pastures, there was a negative effect of body condition on VFI, but no independent effect of the previous level of nutrition. However, there was an interaction between the effects of body condition and her

Abstract:

The deep demersal community of the bathyal Porcupine Seabight is subject to environmental forcing on diel, seasonal and annual scales, in addition to the stochastic and transient influence of nutritional windfalls from the photic zone. The current regime at bathyal depth in the Porcupine Seabight is characterised by oscillations in current flow with periods of 12.4h and 14.8d. Increased current velocity and particle suspension in summer months synchronises well with the seasonal input of phytoplankton to the seafloor. These physical characteristics may constitute time signals in the deep ocean
