Abstract:

Approved for public release; distribution is unlimited.<br>In these days of spiralling software costs and the proliferation of computers, software testing during development is now recognized as a critical aspect of the software engineering process, an aspect that must be improved in terms of cost and timeliness. This thesis describes one method that may guide software testing by analyzing the regions of input associated with each fault as it is detected. These software failure regions are defined and a method of failure region analysis is described in detail. The thesis describes how this ana

Abstract:

Aortic diseases are a common and fatal health issue, regarding various conditions targeting the aorta. The arterial wall consists of two proteins; collagen and elastin (fibers), and they will contribute to the elasticity and strength of the wall. In recent times there has been a growing interest in studying the microstructure of the aortic tissues because it is believed that changes in the amount and/or the construction of the fibers will result in mechanical as well as functional changes that are associated with these heart conditions. Therefore, a better understanding of collagen and its loa

Abstract:

As a fundamental infrastructure, power systems play a vital role in modern society, but it can be damaged by different adverse events e.g. natural, accidental, and malicious, of which the adverse natural events, especially extreme weathers, with huge destructive force can bring tremendous damages and economic losses. The high exposure and comprehensive geographical coverage of the power system make it highly vulnerable to extreme weathers, resulting in equipment damage which leads to cascading failures and blackouts. Traditional methods only focus on modeling and analysing the reliability of

Abstract:

The increasingly popular cloud-computing paradigm provides on-demand access to computing and storage with the appearance of unlimited resources. Users are given access to a variety of data and software utilities to manage their work. Users rent virtual resources and pay for only what they use. In spite of the many benefits that cloud computing promises, the lack of dependability in shared virtualized infrastructures is a major obstacle for its wider adoption, especially for mission-critical applications. Virtualization and multi-tenancy increase system complexity and dynamicity. They introduce

Abstract:

Abstract Heart failure (HF) is a complex pathological state, involving simultaneous alterations in several signalling pathways and changes in gene programming. In HF, activation of the neurohumoral factors and renin-angiotensin-aldosterone (RAA) system occurs as a compensatory mechanism to combat the abnormal ventricular function. Developments in cardiac gene delivery methods have exerted a significant impact to treat HF and to discover the novel molecular mechanisms associated with HF and other cardiac diseases.

Introduction: Trauma is the main cause of death in working-age adults in the UK. Multiple organ failure (MOF) is associated with a high proportion of late trauma deaths, and MOF survivors have poor long-term outcomes. Early prediction of patients at risk of MOF would assist treatment decisions and allow targeted interventions. Methods: A cohort of major trauma patients requiring intensive care unit (ICU) treatment at the John Radcliffe Hospital was identified.

Hospital readmissions related to chronic heart failure (CHF) are costly, widespread, and often avoidable. Patient education that includes diagnosis, causes, medications, diet, exercise, and exacerbation warning signs has been shown to reduce the number of CHF readmissions. The purpose of this study was to use risk stratification to identify CHF patients at high risk for 30-day readmission. Once a high-risk CHF patient was identified, nursing interventions would be triggered to reduce readmissions and close the gaps in the continuum of care following acute care admission.

This study investigates the development of a fiber Bragg grating (FBG) optical sensor network to measure and monitor damage in a composite material induced by low velocity impact events occurring at a single location. The effects of the embedded optical fibers on the host material and their interaction with each other are first considered on both a micro- and macro-mechanics scale. The mechanical low-velocity impact response of two-dimensional woven composite laminates with and without various densities of embedded optical fibers is therefore investigated.

Abstract:

The development and function of the heart is governed by a conserved set of transcription factors (TFs) that regulate gene expression in a cell-type, time point and stimulus driven manner. Of these core cardiac TFs, the most ubiquitously expressed is the zinc finger protein GATA4. In cardiomyocytes, GATA4 is central to proliferation, differentiation, hypertrophy and induction of pro-survival pathways. In cardiac endothelial cells, it is required for valve and septal development, although the exact mechanisms remain unclear. To regulate such a wide array of functions in a spatially and temporal

Abstract:

This paper describes the draft and implementation of a system for identifying failures on the soldered joints from already existing system, which is, however, limited by dependence of the operating system of the human factor. The innovated system provides us an automatic testing of soldered joints using a computer, with subsequent processing of data electronically using the corresponding software. The first part is devoted to the theory of the formation of flaws on the soldered joints and to the familiarization with uninnovated system. Subsequently, work continues with the practical part, whic

Abstract:

Inner hair cells (IHCs) are the primary sensory receptors of the mammalian cochlea. I employed the whole-cell patch-clamp technique to study voltage responses and ionic currents of IHCs in mice bearing mutations in hair bundle proteins. These mutations, all associated with Usher syndrome, lead to structural and functional defects of the mechanosensory hair bundle. I observed developmental failure in the electrical properties of IHCs from these mutants: a continuation of neonatal spiking instead of the graded receptor potentials seen in control adult IHCs. Voltage-clamp recordings revealed the

Abstract:

In this work a data-driven prognostic approach based on AutoRegressive (AR) estimation and hidden Markov models (HMMs) is addressed. In particular, the approach is capable of achieving Prognostic and Health Management (PHM) tasks such as real time detection and Remaining Useful Life (RUL) estimation. The approach can be seen as composed of a training part (offline) and an exploitation part (online). The offline part relies upon the use of a scalar health indicator coming from the system identification field: the Itakura Saito (IS) spectral distance. In particular, raw acceleration data, gathe

Abstract:

Mestrado em Contabilidade, Fiscalidade e Finanças Empresariais<br>Sabe-se que o ambiente corporativo é cada vez mais complexo, pois o gerenciamento de uma organização convive diariamente com a imprevisibilidade e ambiguidade, principalmente, quando a empresa está inserida em mercados dinâmicos e aleatórios. Nestes mercados, as empresas startups ganham cada vez mais espaço face as empresas tradicionais. Nesse sentido, o gerenciamento de risco torna-se uma ferramenta cada vez mais necessária uma vez que visa identificar e gerir a incerteza, analisando quais deles podem impactar os objetivos est

Abstract:

In dieser Arbeit werden zwei Fragen im Zusammenhang mit Fehlern von Fingerabdruckerkennungssystemen untersucht. Erstens: Welche strukturellen Merkmale und begrifflichen Implikationen hat der spezifische Fehlerdiskurs in diesem Teilgebiet der Biometrie? Zur Beantwortung dieser Frage werden im Rahmen einer diskursanalytischen Betrachtung der Fachtexte des Forschungsfeldes die gängigen Fehlertypologien der Biometrie untersucht. Die Arbeitshypothese der Analyse ist, dass der massenhafte Einsatz von Fingerabdruckerkennungssystemen im Alltag trotz aller ihrer Fehler diskursiv durchsetzungsfähig is
