Identification of nonlinear ship motion using perturbation techniques
This thesis presents an identification scheme for the dynamic model of a ship at sea. We determine the form of the governing differential equations for a ship which is free to pitch and roll, but constrained in all other degrees of freedom, using a perturbation-energy technique. This technique …

Parameter Identification of Nonlinear Systems Using Perturbation Methods and Higher-Order Statistics
A parametric identification procedure is proposed that combines the method of multiple scales and higher-order statistics to efficiently and accurately model nonlinear systems. A theoretical background for the method of multiple scales and higher-order statistics is given. Validation of the …

Weak signal identification and inference in penalized model selection
Weak signal identification and inference are very important in the area of penalized model selection, yet they are under-developed and not well-studied. Existing inference procedures for penalized estimators are mainly focused on strong signals. This thesis propose an identification procedure for …

A structured approach to identification techniques for the analysis of industrial processes
… is the development of a structured approach to identification techniques for the analysis of industrial processes that enables industrial users with limited control engineering knowledge to design process models suitable for the design of industrial controllers. This latter aspect has been …

Naming the dead: the identification of the unknown body in England and Wales 1800-1934
The identification of the unknown dead in England and Wales has received little scholarly attention from historians, and this thesis – covering the years 1800 to 1934 – represents its first dedicated study. It engages with, and introduces new perspectives on, the histories of sudden death …

Measurement and Modelling of Human Car Driving with Steering Torque Feedback
… of steering feel is perceived as worse. An identification procedure is initially developed to fit the linear model predictions to measured steering responses in the linear phase of the experiments. The model is found to fit the measured results well under a wide range of conditions, and the …

Metaphors and meaning in the editorials of the New Era newspaper, 2016: A linguistic exploration
… were critically examined using the Metaphor Identification Procedure (MIP), a tool that is used to identify metaphor in discourse. The study is informed by the Conceptual Metaphor Theory (CMT). The investigation reveals that our thoughts and perceptions about target domains are structured in …

Translating conceptual metaphor in popular biomedical texts from English to Arabic
… target domains of these metaphors. The Metaphor Identification Procedure (MIP), proposed by Pragglejaz Group (2007), is used to determine the metaphorical linguistic representation of these metaphors. The discoursal-pragmatic functions of these metaphors are investigated according to the typology …

Observer based velocity and environment force estimation for rigid body control
… and control work in this work; a least squares identification procedure, found in the literature, was implemented for this purpose. Algorithms are developed for obtaining dynamic environment force and torque estimates from position errors in a velocity observer. Obtaining torque estimates from a …

Model-Based Identification of POTS Local Loops for DSL Connectivity Prediction
… We have approached the challenge as an identification problem of the local loop structure and its twisted pair parameters, utilizing single-point measurements made at the provider end of the loop. Once the loop model is obtained, its connectivity measure is readily obtained through …
