Abstract:

A ubiquitous household appliance, the washing machine currently sees a fall in its usage life to a mere 7 years, with valuable and finite resources getting lost to the landfill faster than ever. The reason? Mechanical obsolescence and barriers in repair that make helpless users as far removed from the process as possible. The goal of my degree project is to create long lasting product and service experiences through easier channels of repair and to design deeper partnerships between humans and the appliances that surround them. I want to be part of a rising sustainability movement that aims f

Abstract:

In these last few years, machine learning (ML) has gained incredible traction in the Artificial Intelligence community, and ML models have found successful applications in many different domains across computer science. However, it is hard to provide any formal guarantee on the behavior of ML models, and therefore their reliability is still in doubt, especially concerning their deployment in safety and security-critical applications. Verification and repair emerged as promising solutions to address some of these problems. In this dissertation, we present our contributions to these two lines

Prostate cancer is the most common cancer in males in western societies.

The resistance that hormone refractory disease displays highlights the importance of developing new targeted therapies which may be curative or at least may improve the patient's quality of life and overall survival.

Abstract:

Glioblastoma (GBM) and Medulloblastoma (MB) are the most common brain tumours of adults and children respectively. These tumours are hypoxic as their oxygen levels are lower than the physiological 5-8% O2 found in the brain. Tumour hypoxia can promote tumour cell invasion, increase metastatic potential and leads to resistance to conventional cancer therapies. Chemotherapeutic agents and irradiation induce excessive DNA damage in order to overwhelm the DNA repair pathways and initiate apoptosis. This thesis aimed to examine the impact of hypoxia on DNA repair mechanisms in GBM and MB, which has

Achieving and maintaining public transportation rolling stocks in a state of good repair is very crucial to provide safe and reliable services to riders. Besides, transit agencies who seek federal grants must keep their transit assets in a state of good repair. Therefore, transit agencies need an intelligent predictive model for analyzing their transportation rolling stocks, finding out the current condition, and predicting when they need to be replaced or rehabilitated. Since many transit agencies do not have good analytical tools for predicting the service life of vehicles, this simple predi

Abstract:

Maintenance is constantly challenged with increasing productivity by maximizing up-time and reliability while at the same time reducing expenditure and investment. In the last few years it has become evident through the development of maintenance concepts that maintenance is more than just a non-productive support function, it is a profit- generating function. In the past decades, hundreds of models that address maintenance strategy have been presented. The vast majority of those models rely purely on mathematical modeling to describe the maintenance function. Due to the complex nature of the

Abstract:

The repair of worn or damaged components is becoming more attractive to manufacturers, since it enables them to save resources, like raw material and energy. With that costs can be reduced, and profit can be maximised. When enabling the re-use of components, the lifetime of a component can be extended, which leads to improved sustainability measures. However, repair is not applied widely, mainly because costs of repairing are overreaching the costs of purchasing a new component. One of the biggest expense factors of repairing a metal component is the labourintense part of identifying and quant

In addition to signal processing and subsequent diagnostic and prognostic algorithms these new technologies involve storage of large volumes of both quantitative and qualitative information to carry out maintenance tasks effectively. This not only requires research and development in advanced technologies but a

Abstract:

This thesis aims at explaining two different methods by which failure analysis can be conducted . The two methods were used in two totally different circumstances. One was the failure study conducted at the Petrie Mill of Australian Paper and the other was a study of conveyor belt failures based on the author's experience at Neyveli Lignite Corporation Limited. The bottom line is to stress the need for separate strategies depending on the nature of industry or the machinery and the importance of documenting the actual Failure Analysis however it may be done. This will help in further de

Abstract:

La reconnaissance d'activités de vie quotidienne (AVQs) fait l'objet, depuis des années, de recherches pour proposer des solutions performantes. Elle s'appuie sur l'analyse spatio-temporelle de situations, de comportements, etc. dont les données d'entrée sont les informations fournies par des capteurs ambiants ou par des capteurs portés par la personne. Cette thèse se focalise sur l'instrumentation du lieu de vie par des capteurs ambiants et sur la détection d'un état d'isolement social chez les personnes âgées. Deux approches sont utilisées pour évaluer l'isolement social. La première se base

碩士<br>國立中興大學<br>應用數學系所<br>96<br>This thesis analyzes the M/M/R machine repair problem with second optional repair. Failure times of the operating machines follow an exponential distribution. Repair times of the first essential repair and the second optional repair are assumed to follow exponential distributions. A failed machine may leave the system either after the first essential repair with probability (1-theta) or at the completion of first essential repair may instantly select to repair for second optional repair with probability theta.We obtain the steady-state solutions through matrix-g

碩士<br>國立中興大學<br>統計學研究所<br>99<br>This thesis studies the cost analysis of the M/G/1 machine repair problem with multiple imperfect coverage. When an operating machine fails, it may be immediately detected and located with a coverage probability. We first use a recursive method and supplementary variable technique to develop steady-state analytic solutions. Numerical results of various system performance measures are provided. Next, we construct a steady-state expected cost function per machine per unit time. We use the direct search method and the Newton-Quasi to determine the optimal number of

碩士<br>國立中興大學<br>應用數學系所<br>97<br>This thesis studies the machine repair problem with variable servers in which failed machines balk (do not enter) with a constant probability 1-bn. We assume that the minimum number of busy servers is one. The failure times and repair times are both assumed to be exponentially distributed. We use a recursive method to develop analytic steady-state solutions and evaluate several system performance measures for three cases. A cost model is developed to determine the optimum number of busy servers and the optimal balking rate. We use the direct search method and th

Abstract:

M.Ing.<br>Until very recently reactive maintenance was still used in the mining industry. Equipment failures occurred without warning and resulted in catastrophic breakdowns and large production losses and maintenance cost. As a result, the mining industry turned to preventative maintenance that focused on changing parts before they fail. Although preventative maintenance was an improvement over reactive maintenance practices, equipment reliability did not necessarily improve. Next came predictive diagnostics, which monitored the health of components within assemblies, and thereby predicting t
