Abstract:

Consumers are demanding more and more value for each dollar spent on new electronic equipment. Built-In Self-Test (BIST) of electronic circuits and equipment will help to satiate the demand for self test, self diagnostics, and self repair. This dissertation explores a technique for a Mixed Analog Digital BIST (MADBIST) on a mixed-signal Integrated Circuit (IC). Specifically, on-chip tests for the Analog-to-Digital Converter and Digital-to-Analog Converter on the mixed-signal IC are developed. (The digital portion of the IC can be tested using digital BIST techniques). The tests implemented inc

Abstract:

Exercise on Referral Schemes (ERS) are a widespread community intervention in which health professionals refer patients to a programme of supervised exercise at leisure facilities. National guidance states routine data should be collected and made available for analyses, and that there is a need to better understand what elements of ERS work, for which subgroups of the population. This thesis examines what elements of behaviour change provision within ERS work, for whom and in what circumstances, in order to gain a better understanding of what influences referral to, engagement with, and adher

Abstract:

The National Health Insurance Scheme (NHIS) in Ghana was introduced to alleviate the problem of citizens having to pay for healthcare at the point of delivery, given that many did not have the financial resources needed to do so, and as such were unable to adequately access healthcare services. The scheme is managed from the national headquarters in the capital Accra, through satellite offices located in districts right across the length and breadth of the country. It is the job of these offices to oversee the operations of the scheme within that particular district. Current literature however

This dissertation develops influence diagnostics for crossover models.

The novelty of this dissertation lies in the analytical derivation of influence diagnostics using decompositions of the perturbed mixed models. Consequently, the suggested influence dia

Abstract:

Where possible, policies to improve public health should be evidence-based. Where political pressures and shortage of evidence force action in advance of evidence, effectiveness can be evaluated during policy rollout. Because the aetiology of public health issues is complex, successful policies will likely be complex in their design, their implementation and their interaction with their contexts and target audiences. Process evaluation is therefore crucial in order to inform consistent implementation, and alongside outcomes evaluation, in order to understand how outcomes are produced. However,

Abstract:

Scalar hyperbolic balance laws in several space dimensions play a central role in this thesis. First, we deal with a new class of mixed parabolic-hyperbolic systems on all R^n: we obtain the basic well-posedness theorems, devise an ad hoc numerical algorithm, prove its convergence and investigate the qualitative properties of the solutions. The extension of these results to bounded domains requires a deep understanding of the initial boundary value problem (IBVP) for hyperbolic balance laws. The last part of the thesis provides rigorous estimates on the solution to this IBVP, under precise reg

Abstract:

博士<br>國立成功大學<br>航空太空工程學系碩博士班<br>90<br>A central difference (dissipation-free) scheme has to conserve kinetic energy to avoid numerical instability when a long-term time integration for incompressible flow such as large eddy simulation or direct numerical simulation is performed. A scheme is called fully conservative if it can simultaneously conserve mass, momentum, and kinetic energy in the discrete sense. A theoretical analysis is performed to extend the fully conservative schemes to non-uniform grid systems without sacrificing any conservative properties. The main step is to design a convect

The proposed method pro-vides for well compromise between operational speed and output performance. To obtain higher operational speed, the state equation of a digital filter is implemented by fixed-point format. In contrary, to reduce the distortion occurred from underflow effect, floating-point format is implemented in the output equat

Abstract:

BACKGROUND: In order to accelerate universal health coverage, Nigeria’s National Health Insurance Scheme (NHIS) decentralized the implementation of government health insurance to the States in 2014. Lagos has passed its State Health Scheme (LSHS) into law with a statewide roll out set to commence in 2018. The LSHS aims to improve access to quality care by reducing the financial burden of obtaining care for Lagos residents. Public and private healthcare providers are a critical component of this ambitious insurance roll out. Yet, little or no understanding exists on how to engage providers, the

Therefore, it is necessary and important to remove the noise. The thesis introduces several schemes for the image noise removal: the noise discussed here contains the impulse and Gaussian noise distribution, and both. First filters were designed to process some single noise type. Observe that the noise usually appears in mixed mode in a practical system. When the noise appears in mixed mode, the filters for single noise type menti

Abstract:

Recent years have seen an unparalleled growth in the speed and complexity of VLSI circuits. Analog and mixed-signal circuits are going through a resurgence and continue to pose new challenges to VLSI test engineers. The state-of-the-art in the mixed-signal and analog test domain is to use application-specific test methodologies to tackle individual problems. The same is true for testing the high-speed clock signals used in present day integrated circuits (ICs) for their analog attributes. Jitter is one of the ways of quantifying the accuracy of a clock signal. Present day digital automat

Abstract:

Residual maximum likelihood (REML) estimation is a popular method of estimation for variance parameters in linear mixed models, which typically requires an iterative scheme. The aim of this thesis is to review several popular iterative schemes and to develop an improved iterative strategy that will work for a wide class of models. The average information (AI) algorithm is a computationally convenient and efficient algorithm to use when starting values are in the neighbourhood of the REML solution. However when reasonable starting values are not available, the algorithm can fail to converge. Th

Abstract:

abstract: Cognitive reappraisal, or redefining the meaning of a stressful circumstance, is useful in regulating emotional responses to acute stressors and may be mobilized to up- or down- regulate the stressors’ emotional salience. A conceptually-related but more targeted emotion regulation strategy to that offered by cognitive reappraisal, termed positive cognitive shift, was examined in the current study. Positive cognitive shift (“PCS”) is defined as a point of cognitive transformation during a chronic, stressful situation that alters the meaning and emotional salience of the situation for

The EWMA feedback controller is a popular model-based controller which primarily uses data from past process run to adjust the input recipe for the next run. In the literatures, several papers addressed the efforts of long-term stability and short-term performance of EWMA control scheme. However, in practical applications, multiple-tool and multiple- product production style is common for the practical implementation of R2R contr
