Abstract (sommario):

This paper deals with an optimal replenishment policy for the items having deterministic demand and whose deterioration starts after some fixed time. In earlier studies, it had been assumed that the deterioration of items starts immediately after the procurement, but it's not necessary in most of the cases. For instance, food grains will not start deteriorating immediately after procurement; most of the industrial products also start deteriorating only after some fixed time. Thus, this study removes this unrealistic assumption and considers items whose deterioration starts after some fixed time. The impact of deterioration on cost and how it will impact cycle time has been illustrated in this study. Complete analysis of the proposed model has been done with both optimizing and numerical techniques.

Abstract. The Forbidden city in Beijing is one of the first culture heritage to be listed as UNESCO World Heritage in 1987. The mass and complexity of this imperial palace brings challenges to scientific surveys and documentations. This graduation project adopted the technology of GIS to record, evaluate and analyze historic masonry and their deteriorations across the palace. Aided by ArcGIS, the deterioration degree of every accessible masonry element was accurately and efficiently evaluated and recorded, as well as connected to its precise location among the Forbidden City. All accessible masonry elements in Forbidden City were divided into different types as buildings, walls, foundations, and stairs. The common deteriorations of masonry in Forbidden City were defined and graded according to their degree of severity so that the deterioration was quantified, and a database was established. Before the survey, the mechanism of masonry deterioration in the Forbidden City was presumed to be related to several possible factors. Adopting ArcGIS to set up a database enabled to visualize the distribution of masonry deterioration in the site and lead to a preliminary conclusion, as well as a further mathematic analysis of the data to better understand the cause of deterioration.

Abstract (sommario):

In this paper, we develop an inventory model for non-instantaneous deteriorating items under the consideration of the facts: deterioration rate can be controlled by using the preservation technology (PT) during deteriorating period, and holding cost and demand rate both are linear function of time, which was treated as constant in most of the deteriorating inventory models. So in this paper, we developed a deterministic inventory model for non-instantaneous deteriorating items in which both demand rate and holding cost are a linear function of time, deterioration rate is constant, backlogging rate is variable and depend on the length of the next replenishment, shortages are allowed and partially backlogged. The model is solved analytically by minimizing the total cost of the inventory system. The model can be applied to optimizing the total inventory cost of non-instantaneous deteriorating items inventory for the business enterprises, where the preservation technology is used to control the deterioration rate, and demand & holding cost both are a linear function of time.

Abstract (sommario):

This paper develops an inventory model for items with uncertain deterioration rate, time-dependent demand rate with nonincreasing function, and allowable shortage under fuzzy inflationary situation. The goods are not deteriorating upon reception, but the deteriorating starts after elapsing a specified time. The lead time and inflation rate are both uncertain in the model. The resultant effect of inflation and time value of money is assumed to be fuzzy in nature and also we consider lead time as a fuzzy function of order quantity. Furthermore the following different deterioration rates have been considered: for the first case we consider fuzzy deterioration rate and for the second case we assume that the deterioration rate is time dependent and follows Weibull distribution with three known parameters. Since the inflation rate, deterioration rate, and the lead time are fuzzy numbers, the objective function becomes fuzzy. Therefore the estimate of total costs for each case is derived using signed distance technique for defuzzification. The optimal replenishment policy for the model is to minimize the total present value of inventory system costs, derived for both the above mentioned policies. Numerical examples are then presented to illustrate how the proposed model is applied.

Abstract (sommario):

The nan-agricultural activities of man compete with agriculture for land. The demands on land made by increasing urban, industrial, mining, recreation and other developments, and the attendant infrastructure - largely the result of a fast-growing population - leave an ever-shrinking area for producing food and fibre. Higher yields per unit will be required in future. Land use selection will need to be based strictly on information provided by impact studies which predict the effects that various uses will have on agriculture. A long-term master plan for land use in the R.S.A. is needed.

Abstract (sommario):

Aim: The study aims to determine the types of deterioration that occur in natural stones of the Nebi Mosque, and the effects that cause them to deteriorate, and to draw attention to the importance of protecting the building. The scope of the study is constituted by the findings obtained by observation-based research in light of the current literature. Method: In the study, the deteriorations observed in the basalt stone and limestone of the Diyarbakır Nebi Mosque were examined by photographing in-situ. In addition to the photographs, the types of deterioration on the facades were processed using the mapping method and the areas of the stone surfaces affected by the deterioration types were calculated. The obtained numerical data were used to compare the degradation types quantitatively. Findings: In the stone materials of the building, physicomechanical deterioration such as crack formation, alveolization, and abrasion, which are frequently observed in hot-dry climates, were found. In addition to physicomechanical deterioration, chemical deterioration types such as corrosion, black crust formation, efflorescence/salt crystallization, and microkarst formation and deterioration caused by biological effects were observed. Deterioration caused by faulty repairs examined in the category of anthropogenic deterioration also constitutes the damage observed in the building. In addition to the deterioration detected in the study, it is among the findings to reveal the factors that cause deterioration, such as humidity, wind, air pollution, and faulty repair. Results: Diyarbakır Nebi Mosque, which is a historical and cultural heritage, is damaged by natural stone deterioration due to environmental factors. In the study, the technical properties of basalt and limestone forming the structure were determined and the types of deterioration were included. Attention was drawn to the structure and awareness was tried to be created about taking the necessary measures.

Abstract (sommario):

Multitasking scheduling problems with a deterioration effect incurred by coexisting behavioral phenomena in human-related scheduling systems including deteriorating task processing times and deteriorating rate-modifying activity (DRMA) of human operators are addressed. Under the assumption of this problem, the processing of a selected task suffers from the joint effect of available but unfinished waiting tasks, the position-dependent deterioration of task processing time, and the DRMA of human operators. Traditionally, these issues have been considered separately; herein, we address their integration. We propose optimal algorithms to solve the problems to minimize makespan and the total absolute differences in completion time, respectively. Based on the analysis, some special cases and extensions are also discussed.

Abstract (sommario):

I use porcelain clay because it allows me to focus on the subtle color shifts between white, beige, and gray. The forms I make in clay are associated with tangled roots, naked tree branches, hollow logs, and bones. I reveal this with a dense mass of curvilinear hollow forms that stack into a rhythmic linkage. They twist and turn, relying on gravity to dictate their structure within the installation. The ends of some are closed while others remain open to expose their interior. The tearing and perforations on the surface of each piece are employed to emphasize deterioration. In opposition to the tearing and perforations, I also add concave lines to the surface creating a flowing moving force. The surface is both visually active and smooth, allowing the eye to roam and focus on specific areas. I'm also working with the accumulation of pieces to communicate growth. The individual pieces rest on one another, growing into an interlocking structure. The pedestal is a formal presentation that is specific to the space. For this installation, I wanted to make the work monumental by elevating an accumulation of pieces. When walking around the artwork, there's an opening in the platform for one person to walk in and be surrounded by the two sides of the piece. The work is above eye level and surrounds the viewer at both sides. I want people to view the mass from the outside, but to also have an experience from the inside.

Abstract (sommario):

In this thesis, the main objective is to identify the resilient deformation behaviour of rail trackbed especially in ballast and calculate the stress distribution. A purpose-designed three dimensional Finite Element railway trackbed model is presented in which linear elastic behaviour is assumed in all parts of the model. The study has also evaluated the effects of different variables including moving load magnitude, loading speed and stiffness of materials on stress conditions and deflections based. A comprehensive literature review on a wide background of railway trackbed has been carried out. Railway ballast specifications, deformation mechanisms, resilient and permanent deformation behaviour of granular material, introduction of fouling material and its influence on ballast behaviour are explained to provide the basis for trackbed analysis. Results show that a higher vertical displacement underneath the sleeper may occur when the loading speed is higher than 120km/h. Also, higher speed and Young’s modulus of ballast can result in higher damaging stresses. A stiffer subgrade can result in less rotation of sleeper. A significant effect of subgrade stiffness on stress paths and rotation of sleeper can only be found when Young’s modulus of subgrade is in a low level. Stiffer rail pad can lead ballast element get cracked more easily. Softer pad results in less damaging stresses. In addition, there is no obvious change of either the stress ratio or sleeper rotation as stiffness of the ballast increased.

Abstract (sommario):

Chronic heart failure (HF) is a condition that affects more than 900,000 people in the UK. Mortality rates associated with the condition are high, with nearly 20% of patients dying within one year of diagnosis. Continuous monitoring and risk stratification can help identify patients at risk of deterioration and may consequently improve patients' likelihood of survival. Current repeated-measure risk stratification techniques for HF patients often rely on subjective perception of symptoms, such as breathlessness, and markers of fluid retention in the body (e.g. weight). Despite the common use of such markers, studies have shown that they offer limited effectiveness in predicting HF-related events. This thesis set out to identify and evaluate new markers for repeated-measure risk stratification of HF patients. It started with an exploration of traditional HF measurements, including weight, blood pressure, heart rate and symptom scores, and aimed to improve the performance of these measurements using a data-driven approach. A multi-variate model was developed from data acquired during a randomised controlled trial of remotely-monitored HF patients. The rare occurrence of HF-related adverse events during the trial required the developement of a careful methodology. This methodology helped identify the markers with most predictive ability, which achieved moderate performance at identifying patients at risk of HF-related adverse events, clearly outperforming commonly-used thresholds. Subsequently, this thesis explored the potential value of additional, accelerometer-derived physical activity (PA) and sleep markers. For this purpose, the ability of accelerometer-derived markers to differentiate between individuals with and without HF was evaluated. It was found that markers that summarise the frequency and duration of different PA intensities performed best at differentiating between the two groups and may therefore be most suitable for future use in repeated-measure applications. As part of the analysis of accelerometer-derived HF markers, a gap in the methodology of automated accelerometer processing was identified, namely the need for self-reported sleep-onset and wake-up information. As a result, Chapter 5 of this thesis describes the development and evaluation of a data-driven solution for this problem. In summary, this thesis explored both traditional and new, accelerometer-derived markers for the early detection of HF deterioration. It utilised sound methodology to overcome limitations faced by sparse and unbalanced datasets and filled a methodological gap in the processing of signals from wrist-worn accelerometers.

Abstract (sommario):

The soiling and damage of building surfaces may be enhanced by particulate air pollution, reducing the aesthetic value and lifetimes of historic buildings and monuments. This thesis focuses on the deposition of atmospheric particulate material to building surfaces and identifies potential sources of this material. It also identifies environmental factors influencing two deterioration effects: surface soiling and black crust growth. Two soiling models have been compared to assess their effectiveness in predicting the soiling rates of two materials - stone and wood - in five cities in Europe. An exponential decay model was found to describe the reduction of reflectance well at two of these sites, while a square root relationship is not as effective. Different measures of weekly particulate concentration were not statistically related to soiling rate, whereas S02, rainfall, and temperature were statistically related to reflectance loss over time. Wind speed and solar insolation were also indicated to influence soiling rates. Concentrations of total suspended particulate (TSP), particulate elemental carbon (PEC), total organic carbon (TOC) and thirty-nine particulate-associated hydrocarbons were measured in airborne particles at two sites in London, for one year. These hydrocarbons were also measured in black crusts from St Paul's Cathedral to relate atmospheric and deposited material, and to identify potential sources of the deposited particulate matter. Detailed scanning electron microscope-energy dispersive X-ray (SEM-EDX) analysis of black crust \ similarly indicated potential sources of these deposition layers. Analysis revealed the complex structure of these crusts, comprising gypsum "growth stems ", calcite and large numbers of particles mainly originating from oil combustion. Hydrocarbon analysis supported the fact that oil combustion - probably at Bank power station - was the dominant source of this deposited layer. Other particle morphologies were commonly found, such as those typical of coal combustion and diesel engine exhaust. Metals analyses also indicated other possible sources such as vehicles.

Zwebek, A. I. "Combined Cycle Performance Deterioration Analysis". Thesis, Cranfield University, 2002. http://dspace.lib.cranfield.ac.uk/handle/1826/10462.

Testo completo

Abstract (sommario):

Combined cycles are subject to degradations and hence performance deterioration. According to the author's survey nothing was found in the open literature on this subject. Therefore, it was anticipated that it would be of great achievement if a tool for analysing and diagnosing the deterioration of combined cycle could be produced. So this thesis presents a procedure for combined cycle performance analysis and fault diagnostic by way of simulation. l order to accomplish this task successfully it was necessary to developed two pieces of software. These are STEAMOMATCH for steam cycle performance deterioration analysis, and GOTRESS for GPA of any system. STEAMOMATCH, which is built on the basics of combined cycle thermodynamics, can simulate up to three levels of pressure with reheat. On the other hand GOTRESS uses a Gas Path Analysis technique that enables the user the choice of conducting either linear or non-linear GPA at the same time. I both cases single or multiple fault can be diagnosed. GOTRESS was built in such a way that it makes it a generalised code that can be used not only for combined cycle but to diagnose a wide range of power cycle plants. The deterioration simulation results of the gas turbine power plant showed that the isentropic efficiency deterioration of the turbine unit has the uppermost sever effect on overall gas turbine power output and thermal efficiency. This is also the case with steam turbine (bottoming) cycle power and Rankine efficiency. Also, the simulation results obtained showed that the relationship between the gas turbine size and its performance deterioration is almost constant, i.e. performance deterioration follows the plant's size. Among the two major gas turbine parameters that affects the steam bottoming cycle performance of a CCGT power plant, the gas turbine exhaust temperature has a predominant effect on steam cycle efficiency over the exhaust mass flow.' As a general result, the obtained simulation results showed that the behaviour of CCGT power plant performance is more affected by gas turbine cycle conditions than by steam turbine cycle conditions. The obtained results showed that GPA can be successfully applied to either gas turbine cycle, steam turbine cycle, or the combination of the two in a form of combined cycle. The GPA diagnostic results obtained showed that it would be possible to detect some faults that might occur within the gas turbine that is a part of a combined cycle power plant by monitoring the dependent parameters of the steam turbine (bottoming) cycle such as live steam pressure and temperature and steam turbine power. In contrast, it would not been possible to detect the problems (implanted faults) that might occur within the steam turbine by monitoring the dependent parameters of the gas turbine unit.

Liu, Yawen. "Prediction of pavement surface deterioration". Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/48275/.

Testo completo

Abstract (sommario):

Prediction of pavement performance is important to pavement engineers. Pavement surface deterioration is a dynamic and complicated process. Moisture damage and fatigue are considered as two major causes of pavement deterioration. During a pavement’s service life, the presence of water can lead to loss of stiffness and strength of the asphalt pavement structure. Apart from that, the presence of water can accelerate the propagation and severity of already existing distress. High tensile strain at the bottom of an asphalt layer results fatigue cracking in a pavement. The goal of this research was to develop a series of computational models to predict pavement surface deterioration under the effects of moisture and traffic. The first task was to calculate the pavement surface water pressure under a moving tyre. The water is compressed underneath the tyres, generating a water pressure pulse. This pressure allows surface water to penetrate into the pavement structure. Then the asphalt pavement internal structure (voids distribution) was determined and the water pressure distribution inside the pavement structure was calculated for both fully saturated and partially saturated condition using the surface water pressure. The water pressure expands the voids inside the pavement. Consequently, stress and strain at the edge of the voids, due to frequent traffic passes can lead to failure of the pavement. A ravelling failure probability line was then predicted with the help of cavity expansion theory and asphalt crack propagation law. The case study for the performance of four different asphalt types (HRA, SMA, AC, DBM) using the failure probability calculation shows a good correspondence with their real performance which indicates that this process of predicting failure probability is generally acceptable.

Abstract (sommario):

This research has successfully developed an effective methodology to detect and locate deterioration as well as estimate its severity in the presence of environmental and operational (E&O) variations and high level of measurement noise. It developed a novel data normalization procedure to diminish the E&O variations and high level of noise content; and developed thirteen time-series based deterioration indicators to detect deterioration. The proposed methods were verified utilising measured data from different numerically simulated case studies and laboratory tests, and their efficiency is demonstrated using data acquired from a real-world instrumented building.

Testo completo

Abstract (sommario):

The colonisation of freshly sawn Corsican pine lumber by sapstain and mould fungi was investigated at a sawmill in Hampshire, UK. Three repeat trials encompassing the different seasons of the year were carried out over two years. Results show that fungal colonisation of sawn lumber is dependent on the effect of time of year. Sawlogs were stored for different intervals up to 16 weeks before conversion to boards. Boards were then stored for up to 12 weeks after milling and sampled every 4 weeks to determine the effect of timber ageing on fungal colonisation up to 28 weeks after felling. The metabolic activity of wood cells over the period after felling of the original tree was also measured. It was evident that the defacement of boards reached maximum levels after 12 weeks exposure irrespective of seasonal influences. Initial levels of fungal growth on lumber were reduced if the boards were milled from logs stored for a period prior to conversion. Investigations into the metabolic activity of the wood cells revealed significant levels of respiration taking place up to 28 weeks after felling of the original tree including 12 weeks post-conversion into boards. Boards were used to make a nested stack arrangement allowing plastic tanks top be placed in the centre. The tanks contained a sub-sample of the full-size boards in order to investigate insect activity and effects of gammairradiation. A total of 115 insect species representing 16 of the 34 British orders were collected during the trials. Seventy-two percent of these insects were collected from within the stacks of lumber and investigations using sealed tanks containing boards showed that the insects could influence the fungal colonisation of sawn lumber. Despite the relatively short length of the trials, a succession of insect colonisation from fungivores through to predators and detritivores was recorded. Boards, which were sterilised by gamma-irradiation, were preferentially colonised by mould fungi and subsequent internal staining was confined to the outer surface. Trials with short-length billets allowed the wood-colonising ability of selected sapstain fungi to be investigated under controlled conditions following sterilisation by gamma-irradiation or autoclaving, and storage at 30°C and 20°C. Lesion formation in gamma-irradiated tissue was solely due to the fungus potentially conditioning the wood for colonisation. Colonisation studies also revealed that different fungi exhibit different strategies enabling them to infect timber. Pathogenic species demonstrated a relatively fast initial growth rate to establish themselves before triggering any host anti-fungal responses in the wood. The characteristic lesions created in the billets were investigated using light and electron microscopy to reveal hyphal invasion and or/ wood cell modifications. Respiratory activity of the lesions was elucidated using radioactively labelled glucose allowing the metabolic pathways to be ascertained and demonstrated that wood tissue in the apparently healthy regions adjacent to the lesions reacted as if infected. Future work considers the possibility of biocontrol, using insects in combination with gamma-irradiation of sawn lumber and also further investigations into the reaction zones produced by the fungus growing in the wood.

Abstract (sommario):

The National Bridge Inventory bridge inspection system ranks the condition of bridge components on a scale of zero to nine. The resulting condition ratings represent an important element considered in deciding measures for bridge maintenance, repair, and rehabilitation. Thus, forecasting future condition ratings well is critical to reliable planning for these activities and estimating the costs. The Illinois Department of Transportation currently has deterministic models for this purpose. This study’s objective is to review the current models using condition rating histories gathered from 1980 to 2020 in Illinois for the following bridge components: deck, superstructure, substructure, culvert, and deck beam. The results show the current Illinois Department of Transportation models are inadequate in forecasting condition ratings, producing overestimates of the transition times between two condition rating levels for these components / systems, except for the deck beam, which is underestimated. It is recommended that the mean transition times found in this study from condition rating histories are used to replace the current models as a short-term solution. Further research is recommended to develop probabilistic models as a long-term solution to address observed significant variation or uncertainty in condition rating and transition times between condition rating levels.

Testo completo

Abstract (sommario):

The selection and prioritization of field locations that most warrant direct examination of the pipe or other maintenance activities requires prediction of the coating conditions and the environmental conditions underneath a disbonded coating, which may support corrosion or cracking.� Current above ground measurements provide little information and to improve our ability of site-selection, this project considered a combined experimental and modeling approach to specifically identify those coating properties and environmental conditions that can lead to damaging SCC environments. Soil box experiments indicated that near-neutral pH SCC environments are supported by shielding coatings and intermediate conductivity soils, where increased pH levels can be the result of improved current penetration in high conductivity soils or low buffering capacity in low conductivity soils.� As the pH increases, the environment becomes less conducive to near-neutral pH SCC.� TECTRAN modeling indicated an important role of coating permeability to CO2 in maintaining a near-neutral pH.� Degradation of the mastic adhesive may be another source of CO2.
