Full textAbstract:
YesPredicting the PDC bit performance during drilling operation is important for the cost effectiveness of the operation. The majority of PDC bits are assessed based on their performance that are relative to offset wells. Determination of mechanical specific energy (MSE) in real time and compare it with the known MSE for a sharp bit to assess the bit life has been utilized by several operators in the past. However, MSE still cannot be used to predict the bit performance in exploration wells and also it cannot assess the bit efficiency in the inner and outer cones. A more precise approach needs to be devised and applied to improve the prediction of bit life and the decision when to pull the bit out of the hole. Effective mechanical specific energy (EMSE) developed in this work is a new wear and performance predictive model that is to measure the cutting efficiency based on number of cutters, which contact the rock as a function of weight on bit (WOB), rotary speed (RPM), torque, and depth of cut (DOC). This model modifies the previous MSE model by incorporating such parameters and including detailed design of the bit, number of blades, cutter density, cutter size, and cutting angle. Using this approach together with the analysis of rock hardness, a level of understanding of how the drilling variables influence the bit performance in the inner and outer cone is improved, and a convenient comparison of the bit condition in the frame of the standard bit record is achieved. This work presents a new simple model to predict the PDC cutters wear using actual data from three sections drilled in three oil wells in Libya. It is found that the obtained results are in well agreement with the actual dull grading shown in the bit record.

In this thesis, we would like to present a new way to enhance the “depth map” image which is called as the fusion of depth images. The goal of our thesis is to try to enhance the “depth images” through a fusion of different classification methods. For that, we will use three similar but different methodologies, the Graph-Cut, Super-Pixel and Principal Component Analysis algorithms to solve the enhancement and output of our result. After that, we will compare the effect of the enhancement of our result with the original depth images. This result indicates the effectiveness of our methodology.Room 401, No.56, Lane 21, Yin Gao Road, Shanghai, China

"A study of the cutting performance in multipass abrasive waterjet machining of alumina ceramics with controlled nozzle oscillation." Publisher:University of New South Wales. Mechanical & Manufacturing Engineering, 2008. http://handle.unsw.edu.au/1959.4/41216.
Full textAbstract:
An experimental investigation has been undertaken to study the depth of cut in multipass abrasive waterjet (AWJ) cutting of an 87% alumina ceramic with controlled nozzle oscillation. The experimental data have been statistically analysed to study the trends of the depth of cut with respect to the process parameters. It has been found that multipass cutting with controlled nozzle oscillation can significantly increase the depth of cut. Within the same cutting time and using the same cutting parameters other than the jet traverse speed, it has been found that multipass cutting with nozzle oscillation can increase the depth of cut by an average of 74.6% as compared to single pass cutting without nozzle oscillation. Furthermore, a multipass cutting with higher nozzle traverse speeds can achieve a larger depth of cut than a single pass cutting at a low traverse speed within the same cutting time. A recommendation has been made for the selection of appropriate process parameters for multipass cutting with nozzle oscillation. In order to estimate the depth of cut on a mathematical basis, predictive models for the depth of cut in multipass cutting with and without nozzle oscillation have been developed using a dimensional analysis technique. The model development starts with the models for single pass cutting which are then extended to multipass cutting where considerations are given to the change of the actual standoff distance after each pass and the variation of kerf width. These predictive models has been numerically studied for their plausibility by assessing their predicted trends with respect to the various process variables, and verified qualitatively and quantitatively based on the experimental data. The model assessment reveals that the developed models correlate very well with the experimental results and can give adequate predictions of this cutting performance measure in process planning.

Full textAbstract:
L'objectif de cette thèse est d'observer l'impact des coups de couteaux sur différents tissus en aramide et d'analyser les facteurs influents. On peut se défendre d'une attaque mais une blessure ne peut être complètement évitée. L'objectif est d'absorber un maximum d'énergie, de façon à réduire le risque de blessure. Les mécanismes de perforation par une lame sont complexes. L'étude a révélé une demande dans ce domaine, car la plupart des solutions proposent des armures lourdes contenant du textile. Cet assemblage de matériaux a des inconvénients, comme le poids trop élevé et le manque de souplesse. D'autres chercheurs recommandent des solutions textiles parce qu'elles sont souples et déjà utilisées dans le domaine balistique. Les recherches menées pour cette thèse ont pour but de contribuer au développement de types de textile résistant aux coups de couteaux. C'est la raison pour laquelle, non seulement les propriétés de la matière textile doivent être analysées, mais aussi l'attaque au couteau en elle-même, pour développer une meilleure protection. Il a été démontré que beaucoup de facteurs influent sur le niveau de protection et rendent sa perception difficile. Des recherches ont été réalisées pour évaluer les paramètres de test, qui sont définis dans le test standard, mais aussi pour ceux qui n'y sont pas définisThe research goal of this thesis is to examine various aramid fabrics with regard to their stabbing behaviour and to find influencing factors to this. An attack can only be inhibited, but an injury cannot be completely prevented. The goal is always to absorb as much energy as possible, so that the penetration is thus reduced and the risk of injury decreases. The stab mechanism is a complex and variable process. The review showed the demand on research in this area, because the most solutions involve hard body armour parts in combination with fibrous materials. This material combinations show many disadvantages with regards to the high weight and the missing flexibility. Other researchers also recommend textile solutions, because they are flexible and in the field of ballistic panels they are already used. The investigations carried out within this thesis are done to contribute to the development of pure textile stab-resistant panels. Therefore the interdependencies between the physical properties of the material but also the mechanism during a stab attack have to be recognized, to developed higher protection levels. It was shown, that the multitude of factors causes the problem to define a level of protection. General investigations were done to analyse the test parameters, which are defined in the test standard but also this one, which are missing

Full textAbstract:
In this work an application for evaluating different 3D displays is developed. The work is carried out in collaboration with Setred AB that develops an autostereoscopic display. A stereoscopic display lets the user see different perspectives of a scene with each eye. A presentation of previous research within depth perception and stereoscopic 3D displays is made. Based on results from previous evaluations, a test environment is designed. It is implemented in C++ and OpenGL and a small Interface Library is developed. A couple of test sessions are carried out with a relative small number of subjects to provide results for an evaluation of the test environment. Results from the evaluation are used in combination with previous research to conclude the design of an evaluation environment. Tracking 3D paths is suggested as a suitable task for evaluating 3D displays. Three types of parameters are suggested for use as dependent variables: response time, rate of correct answers and accuracy. The parameters are used in the evaluation environment developed. One test developed intends to give an appreciation of how small differences in depth that are noticeable on the display. No distinct value for the depth resolution is found. In a scene influence test, the task is to position three objects in specific places on the walls of a room. For this test the accuracy is measured and used as the dependent variable. The presence of a reference structure improves the result in this test. Two different tests are carried out to evaluate occlusion. A number of tiles are to be ordered in increasing depth and the error rate of the ordering is used as dependent variable in this test. The results from the two tests indicate that occlusion overrides binocular disparity. A user interaction test that requires movement in three dimensions is developed. It evaluates six different methods to do this. The keyboard interaction method is preferred by some of the test subjects and provides the best results.

Full textAbstract:
In appreciation of High-Performance Computing, modern scientific simulations are scaling into millions and even billions of grid points. As we enter the exa-scale, new strategies are required for visualization and analysis. While Image-Based Rendering (IBR) has emerged as a viable solution to the asymmetry between data size and its storage and required rendering power, it is limited in its 2D image portrayal of 3D spatial objects. This work describes a novel technique to capture, represent, and render depth information in the context of 3D IBR. We tested the value of displacement by displacement map, shading by normal, and image angle interval with our technique. We ran an online user study of 60 participants to evaluate the value of adding depth information back to Image-Based Rendering and found significant benefits.Master of Science
In scientific research, data visualization is important for better understanding data. Modern experiments and simulations are expanding rapidly in scale, and there will come a day when rendering the entire 3D geometry becomes impossible resource-wise. Cinema was proposed as an image-Based solution to this problem, where the model was represented by an interpolated series of images. However, using flat images cannot fully express the 3D characteristics of a data. Therefore, in this work, we try to improve the depth portrayal of the images by protruding the pixels and applying shading. We show the results of a user study conducted with 60 participants on the effect of pixel protrusion, shading, and varying the number of images representing the object. Results show that this method would be useful for 3D scientific visualizations. The resulting object almost accurately resembles the 3D object.

Hone, Geoffrey Noel. "Brightness and contrast as cues to depth in the simulator display : cue combination and conflict resolution." Thesis, University of Surrey, 1994. http://epubs.surrey.ac.uk/842731/.
Full textAbstract:
When computer generated images are used for real-time display in simulator applications, much of the fine detail available from the natural world, or even from video-film, is not available to an observer. This lack of detail leads to a reduction in the number of sources of depth information (cues to depth) that are available to specify the layout of the displayed scene. Amongst the cues normally available are luminance gradients and luminance contrast gradients, each deriving from luminance differences between components of the displayed scene; however, in computer generated images, these two cues do not always conform to the intended natural world image, and can offer conflicting information. While not referring explicitly to luminance gradients, Ames (1949) demonstrated that the brighter of two otherwise identical objects would appear nearer; his Demonstration 18 offering a negative luminance gradient similar to that arising in the natural world from atmospheric perspective. Similarly, Ross (1967, 1993) and O'Shea, Blackburn and Ono (1994) have shown a similar effect to Ames (1949), but with higher contrast replacing increased brightness, which they liken to the negative luminance contrast gradients that are also available in the natural world due to atmospheric perspective. The luminance gradient, and luminance contrast gradient cues are generally in accord when the scene background is light, but are in conflict where the background is dark. The experiments reported here show that either gradient can function as a cue to depth, and hence to the spatial layout of a depicted scene, and that conflicts between them are resolved in a way that takes into account the amount and type of other depth information available to an observer. Such a form of conflict resolution and cue combination is in accord with the separate items of depth information being processed either partly or wholly in parallel, so that the strength of each cue is determined by reference to the other available cues. When applied to simulators using computer generated images, these results suggest that both users, and scenario designers, require an awareness of the possible effect of a change to any item of depth information, and in particular to depth information that has its origin in luminance differences between objects in the depicted scene.

Full textAbstract:
This thesis examines the Templo Santa Muerte in Los Angeles, a small, loosely organized spiritual group dedicated to the veneration of La Santa Muerte, or the Holy Death. Although originating in the urban barrios (neighborhoods) of Mexico City, Santa Muerte is now venerated in the southwestern United States as well, primarily among working-class Mexican Americans. Although Santa Muerte has been condemned by the Catholic clergy and vilified in mass media and popular culture for its ties to crime and gang violence, my fieldwork at the Templo Santa Muerte demonstrates that not all devotees of Santa Muerte can be characterized in this way. For Templo members, Santa Muerte is foremost a supernatural instrument whose appeal is in large part derived from her singular commitment to satisfying their corporeal needs and material wishes. While this quality is also attributed to many Catholic saints, Santa Muerte is believed to operate independently of Church orthodoxy and is viewed to be more powerful because of this. The Templo Santa Muerte, on the other hand, incorporates some features of formal Catholic liturgy while simultaneously organizing its services around the individual petitions of its members. In doing so, the Templo’s founders maintain an effective balance between liturgical features familiar to their mostly Catholic members and the fundamentally instrumental relationship they have with Santa Muerte. I argue that this balance is central to the appeal of the Templo and to the logic of its founders, who took advantage of the tolerant and diverse cultural atmosphere of Los Angeles to establish a spiritual enterprise that is truly the first of its kind. My methodology and theoretical approach acknowledges this, favoring an ethnographic examination grounded in respondent testimonies, direct observations, and relevant ethnohistorical interpretations of the symbolism and ritual behavior associated with Santa Muerte. At its most general, my analysis of the cult and Templo of Santa Muerte is framed around three separate but mutually interactive and informative dimensions: the instrumental and social manifestations of the cult and Templo, respectively, and the structuring influence that Catholic soteriology and cultural materialism exerts over both.

Full textAbstract:
This thesis is about infancy, independence, and how medicalisation shapes mothers' perceptions of their infants. It draws on ethnographic research in Cardiff, undertaken during a period of heightened concern about the Sudden Infant Death Syndrome (SIDS), and funded by the Foundation for the Study of Infant Deaths. Three "cultural constructions" of infancy are juxtaposed: the vulnerable and constantly accompanied Bangladeshi infant, the Welsh or English infant encouraged towards independence, and the autonomous infant of epidemiological analysis. The thesis shows how the processes of medicalisation brought contrasting perceptions of infancy to light, suggesting that Bangladeshi women taking part in an "English for Pregnancy" project were not only learning language, but also learning about medicalised infant care. It argues too that health professionals shape the way in which mothers perceive their infants through the introduction of the language of "risk factors". The infant body itself emerged at the boundary of powerful systems of meaning. If the boundaries of the Bangladeshi infant body were blurred through constant contact, those of the Welsh or English infant were marked intermittently through alternating periods of solitude with "attention". Some Welsh and English mothers spoke of infants and their care in terms of the care of domestic animals, and the mothers' own ambivalence about their own animality, while some Bangladeshi mothers spoke of the spiritual power and vulnerability of infants, and in doing so articulated their links with Bangladesh. For health professionals the infant body was a site for demonstrating expertise through both research (which constructed ethnic minorities as 'natural') and recommendations for action. The thesis discusses the location of contemporary anthropology at cultural boundaries. Juxtaposing contrasting beliefs about infancy revealed very different perceptions of independence, marked in particular by contrasting perceptions of time, space, and the infant body itself.

Full textAbstract:
This thesis examines mythic representations of death- and Underworld-related divinities in light of contemporary archaic and early classical Greek associated cultic practice. Current scholarly approaches to these so-called ‘chthonic’ divinities generally adopt a view of the divine framework of the Underworld which places death-related concerns as the primary focus of the divinities concerned. In this project I have looked at Hades, Persephone, Demeter, Hekate and the Moirai and Keres for analysis of this framework. This thesis demonstrates that the death-related functions of these divinities were not the principle factor in their characterisations, but were rather only one aspect of a more nuanced identity. More generally, this thesis demonstrates that the ways that the Greeks viewed death and utilised death-related gods in cultic and literary representations support the idea that the association with death was not the primary aspect of any of these divinities. By investigating the mythic characterisations and cultic realities of these divinities, utilising the methodological approach of thin-coherence, this thesis shows that a more nuanced picture emerges. This thesis contributes a new approach to the death-related divine, demonstrating primarily that their death-related function is not the primary source of cultic dedication. In cases where a death-related divinity does not receive cultic dedication, or significant cultic dedication, the death-related function found in their mythic profile remains their primary function. I show that death-related gods who receive cultic dedication do so within the remit of other areas of interest, and this is most usually demonstrated in the contrasting tropes death/fertility, death/agriculture, and death/marriage. These tropes are demonstrated in various ritual activities throughout this thesis. Therefore, this project shows that death is an area of concern that permeates the world of the living and is not separate from it.

En esta tesis, el focus profile es propuesto como una alternativa a conceptos clásicos como la profundidad de campo. Los nuevos conceptos introducidos en esta tesis son aplicados a diferentes problemas relacionados con el foco, tales como la adquisición eficiente de imágenes, estimación de profundidad, integración de elementos perceptuales y fusión de imágenes. Los resultados experimentales muestran la aplicación exitosa de los modelos propuestos.The focus of digital cameras plays a fundamental role in both the quality of the acquired images and the perception of the imaged scene. This thesis studies the focus cue in conventional cameras with focus control, such as cellphone cameras, photography cameras, webcams and the like. A deep review of the theoretical concepts behind focus in conventional cameras reveals that, despite its usefulness, the widely known thin lens model has several limitations for solving different focus-related problems in computer vision. In order to overcome these limitations, the focus profile model is introduced as an alternative to classic concepts, such as the near and far limits of the depth-of-field. The new concepts introduced in this dissertation are exploited for solving diverse focus-related problems, such as efficient image capture, depth estimation, visual cue integration and image fusion. The results obtained through an exhaustive experimental validation demonstrate the applicability of the proposed models.

Full textAbstract:
Stereoscopic displays provide 3D vision usually with the help of additional equipment such as shutter glasses and head gears. As a new stereoscopic display technology, autostereoscopic 3D Displays provide 3D vision without additional equipment.
Previous studies of depth and distance estimation with autostereoscopic displays indicate the users do not exhibit better performance in 3D. Yet, they claim 3D displays provide higher immersiveness.
In this study, perception of the angle of a 3D shape is investigated by comparing 2D, 3D and Real perception cases. An experiment is conducted using an autostereoscopic 3D display. Forty people have participated in the experiment. They were asked to estimate the vertex angle and draw the projections of the object from two different viewpoints. It is found that users can better estimate the angles on a cone when viewed from the top on an autostereoscopic display. This may contribute positively to 3D understanding of the scene.
Results revealed that participants make more accurate angle estimation in autostereoscopic 3D displays than in traditional 2D displays. In general, the participants&rsquoangle drawings were slightly higher than their angle estimations. Moreover, the participants overestimated 35, 65 and 90 degree angles and underestimated 115 degree angle in autostereoscopic 3D display.

The study investigated the contribution of information leaflets to
advice and practice in infant care within the wider context of parent
learning. Two leaflets about reducing possible risks of cot death
were of particular interest. The practices selected for study were
infant feeding, sleep position and warmth assessment choices. As well
the clothing, bedding and heating arrangements of babies in bed at
night were described and compared with practices of Christchurch
parents in 1986.
Ninety seven maternity patients at Christchurch Women's Hospital were
interviewed in hospital and 53 of these, who were new mothers, were
interviewed again at home when their babies were about three months
old. The hospital interviews gathered information about promoted
behaviours, sources from which written and verbal advice were received,
women's perceptions of written and verbal advice received and their
intended choices for infant feeding, sleep position and warmth
assessment. The home interviews gathered information about written and
verbal advice sought and received since the baby's birth, women's
perceptions of this advice and of their learning experiences, actual
infant feeding, sleep position and warmth assessment choices. Evidence
of behaviours was obtained by three consecutive days of diary recording
for infant feeding and sleep position, and by observation for infant
warmth assessment. Details of clothing, bedding and heating
arrangement for babies in bed at night were also gathered. Promoted behaviours were breastfeeding , the side sleeping position, and
to a lesser degree, feeling the torso to assess an infant's warmth.
These behaviours were consistent with those promoted in the cot deathrelated
leaflets. Doctors in particular, and health professionals in
general were women's most trusted sources for advice about infant care.
Written information reported to have been seen was generally reported
to have been read by hospital subjects and readers were representative
of the total sample. Materials in the Plunket information pack were
well read and more than half the home subjects reported reading most of
the materials. The cot death related leaflets were amongst those most
often reported to have been read (by more than three quarters of
subjects), perceived to have been helpful and thought worth
recommending to other parents. Hospital subjects' intended choices of
infant care were breastfeeding for 85, the side sleeping position for
89, and feeling the torso to assess infant warmth for 34 subjects. By
the time their babies were three months old a significant number of
home subjects had changed from their intended practices. Twenty five
women had changed from fully breastfeeding (chi²=26.0, df 1, p

Full textAbstract:
This thesis explores the imagery of funerary ritual that expresses the commemoration of both the living and the dead in the art of the marble cinerary memorials of the early Empire. This group of objects includes decorated marble artefacts associated with cremation burial between the Augustan period and the reign of Antoninus Pius: ash chests (or cineraria); ash altars and grave altars (with or without ash cavities); as well as round urns and vase-shaped urns. The iconography chosen for cinerary memorials by individuals in the early Empire reflects those individuals’ concerns to remember families and friends and in turn to be remembered. This research approaches the analysis of funerary iconography holistically as embedded in its contemporary culture, as opposed to the focus on the art of various sub-cultures of Roman society, seen in recent scholarship. Items with adequate ancient provenance are used to create a sample dataset that represents individuals that belong to a middle to high income-group of society, individuals that are united through their ability to pay and commission these memorials, rather than by class. The epigraphic material, studied alongside the tomb analysis, indicates that this socio-economic group included people of different legal statuses: slaves, freed-people, non-elites and known-elites. Thus we are able to examine how artistic motifs, and also imperial iconography and culture, were received by a cross-section of society. The use of semiotics allows symbols to be analysed in conjunction with other methods such as examining narration and abstraction. This theoretical framework results in the extraction of meaning from seemingly generic motifs and connects this interpretation with contemporaneous cultural norms. Using these methods and the sample dataset, the memorial typology is examined as indicative of a focal point for funerary cult, through the connection between the object as a replacement altar for ritual, and as a house or shrine for the commemoration of the dead. The iconography associated with the memorials therefore relates to both the ritual context (garlands and other ritualistic motifs) and to the object as a small building (the architectonic façade and doors; garden and vegetative iconography). It also relates to the commemoration of the dead (portraiture and honorific iconography) and in particular to the idea of the spirit or manes of the deceased as being immortalised through the memorial (underworld and mythological iconography). All elements, then, point to the focus of the object in funerary ritual which enables the living to honour the spirit of the deceased and acts as a memento of family and friends, bringing together both the living and the dead in art and inscription.

Full textAbstract:
Doctor of Public HealthFor many years the major cause of infant mortality in NSW has been the result of Sudden Infant Death Syndrome (SIDS). Statistics show the area defined as 'Western Sydney' is no exception, and in 2002, a report prepared by the Epidemiology, Indicators, Evaluation and Research Unit (EIRE) in Western Sydney presented data indicating SIDS rates in the area were higher than the state average. In particular, two Local Government Areas (LGAs) had clusters of SIDS deaths. Previous Australian research identified a higher risk of SIDS and other causes of infant mortality in Aboriginal and Torres Strait Islander populations. The areas of Western Sydney where SIDS rates were higher than expected were home to Aboriginal, Torres Strait Islander and Pacific Island residents. The number of SIDS deaths in Aboriginal infants did not explain the higher than expected rate of SIDS in the areas under investigation. Studies undertaken in New Zealand and the Pacific Islands have identified higher than expected risk of SIDS in Maori and Pacific Island communities in those countries, although this has never been studied in Pacific Island residents living in Australia. The reasons for these communities exhibiting a higher than normal SIDS rate is not completely understood, but can be partially explained by behavioural practices which are known to impact adversely on the risk of SIDS. This study sought to investigate the level of knowledge concerning the prevention of sudden and unexpected death in infants (SUDI) in three key groups of infant caregivers: general practitioners, nurses and parents living or working in the area geographically defined by Sydney West Area Health Service (WSAHS). In addition, the study sought to identify any variation in knowledge of SIDS reduction strategies in the three groups under study, and to investigate factors influencing knowledge and practice in these participants. The study findings were then used as a basis on which to develop strategies and recommendations to enhance the delivery of safe sleeping messages through the health care system. Using a combination of qualitative and quantitative methods, this cross-sectional study highlights a number of issues around infant care practices and the major influences on new parents living in a multicultural community. Results of the study showed there is a large variation in knowledge around safe sleeping practices (including SIDS reduction strategies) in all the groups studied. Although educational campaigns are conducted regularly, many general practitioners and parents are confused about the key SIDS reduction messages and still place infants in sleeping positions considered unsafe. While nurses and midwives were aware of the SIDS reduction strategies, they still occasionally used infant sleeping positions considered unsafe. General practitioners born overseas in a country where English is not the first language were less likely to be familiar with safe sleeping messages, including SIDS reduction strategies. Families from a Culturally and Linguistically Diverse (CALD) background were less likely to have seen SIDS information in their own language than families who spoke English, and as a result were more likely to use traditional methods of infant care, including co-sleeping with siblings and parents and side or tummy sleeping. CALD parents were more likely to rely on herbal remedies and friends and family for assistance, than English speaking parents who accessed health professionals as the first point of call when infants were unwell. The study identified a relatively recent practice, which until reported in this study, has not been documented in the literature. The practice of draping infant prams with blankets originated from the Cancer Council of Australia guidelines which recommend covering a pram with a light muslin wrap to protect infants’ skin from the sun. It appears parents have misinterpreted this message and are covering infant prams with blankets to encourage sleep, even when sun exposure is not an issue. Research suggests that poor air quality around the head of an infant may affect an infant’s arousal response. While no research has been conducted on the air quality around an infants head when covered by a heavy blanket in a pram, it is possible based on research into air quality around infants, that that this practice may increase the risk of sudden and unexpected death in an infant. In conclusion, this study found that multiple changes to the SIDS reduction messages since the initial ‘Reduce the Risks’ Campaign have led to confusion about ways of preventing SIDS in GPs, nurses and parents in Western Sydney. The study makes seven recommendations aimed at improving knowledge of safe sleeping practices in these groups, and optimizing health outcomes for infants using a collaborative approach to service delivery and future initiatives.

Ce travail propose d’étudier les relations complexes entre métaphore, tabou et X phémisme. Plus spécifiquement, il analyse la manière dont les domaines tabous de la maladie, de la mort et du sexe sont représentés par le biais de la métaphore dans un corpus de séries télévisées américaines constitué de House, M.D., Grey’s Anatomy, Six Feet Under, How I Met your Mother et Sex and the City. Il s’articule autour de trois chapitres. Les deux premiers permettent de définir le cadre théorique. Dans un premier temps, nous définissons le concept de « tabou » et tentons de dégager les origines historiques et sociales des tabous étudiés. Cela nous mène également à définir les X phémismes – qui sont privilégiés pour mentionner les sujets tabous – et les différentes matrices lexicogéniques qui permettent leur création. Le second chapitre est consacré à la définition de la matrice qui nous intéresse dans le cadre de ce travail : la métaphore. Il adopte une approche cognitiviste et vise essentiellement à exposer le cadre théorique relatif à la métaphore qui est utilisé dans le dernier chapitre. Enfin, le troisième chapitre propose une analyse des métaphores relevées dans le corpus. Il s’agit d’étudier l’influence du domaine source sur la conceptualisation X phémique et les différentes fonctions que peuvent revêtir ces métaphores. Tout au long de ce travail, nous nous attachons à expliquer en quoi les métaphores sont un outil privilégié pour la création de métaphores relatives à des sujets tabous et à réfléchir sur le statut particulier des métaphores dans les séries téléviséesThis study explores the complex relations between metaphor, taboos, and X phemisms. More specifically, it focuses on the representation of the taboos of disease, death, and sex through metaphors in a corpus constituted of five American TV series, House, M.D., Grey’s Anatomy, Six Feet Under, How I Met your Mother et Sex and the City. It is divided into three chapters. The first two chapters aim to define the theoretical framework. The study starts with a definition of the concept of “taboo” and its social and historical origins. It leads us to a definition of X phemisms – which are favored to mention taboo topics – and the different word-formation processes that are used for their creation. The second chapter is devoted to the definition of the word-formation process that is central in this study: metaphor. The approach is mainly cognitivist and the aim of the chapter is to define the Conceptual Metaphor Theory. Finally, the last chapter consists in an analysis of the metaphors of the corpus. The aim is to study the influence of the source domains on the creation of metaphorical X phemisms and the different functions that those metaphors may fulfil. One of the main objectives is to explain why metaphors are favored to create metaphors related to taboo topics and to shed light on the particular status of metaphors in TV series

No presente trabalho foi avaliado o efeito da microestrutura e da capacidade de suportar carregamento de camadas nitretadas produzidas em aços ferramenta AISI H13 e AISI D2 sobre a aderência e a resistência ao desgaste microabrasivo de revestimentos de TiN-PVD. Em cada um desses aços, foram produzidas camadas nitretadas de diferentes estruturas e espessuras, e foram determinadas experimentalmente as curvas potencial início de formação de camada branca, para a nitretação a 520oC. Para o aço ferramenta AISI H13, o emprego de tempos de pré-tratamento de nitretação mais prolongados ( aproximadamente 11 h) foi necessário para aprofundar a camada nitretada e, conseqüentemente, aumentar a capacidade de suportar carregamento dos revestimentos, evitando a formação de bordas que provocam o lascamento e a escamação das camadas de TiN. Observou-se que esse tipo de falha persiste se a zona de endurecimento for pouco profunda, uma vez que a transição de propriedades mecânicas da camada de TiN para o núcleo não nitretado continua abrupta e a capacidade de suportar carregamento da camada nitretada ainda é baixa. Por outro lado, curtos tempos de nitretação (aproximadamente 42 min.) foram suficientes para aumentar a aderência das camadas de TiN ao aço ferramenta D2, pois o núcleo não nitretado desse aço possui uma capacidade de suportar carregamento razoável. Observou-se que a resistência ao desgaste microabrasivo e a aderência dos revestimentos são prejudicadas com a presença de uma camada preta na interface camada de TiN/camada nitretada. Quando a superfície dos revestimentos é carregada, falhas do tipo casca de ovo facilmente ocorrem.In this work, the influence of both the microstructure and the load-bearing capacity of nitrided layers, formed on top of AISI D2 and AISI H13 tool steels, on adhesion and wear resistance of PVD-TiN coatings was studied. The threshold nitriding potential curves for the above mentioned steels and the optimum conditions of the pre-treatments which increased the adhesion as well as the wear resistance of the PVD-TiN were determined experimentally. By using longer nitriding times (about 11 h) and lower nitrogen contents in the gas mixture (about N2-5%vol.), it was possible to minimize the pile-up degree of the TiN/H13 nitrided substrates and, consequently, the occurrence of coatings chipping. This flaw persists when the nitrided layer is thin, due to an abrupt transition of mechanical properties at the TiN coating / steel core interface. Shorter nitriding times (about 42 min.) and lower nitrogen contents (about N2-5%vol.), on the other hand, are sufficient to guarantee a better adhesion of TiN coatings on AISI D2 tool steel, as the core of such steel possesses relatively better load-bearing capacity than the AISI H13 tool steel. The presence of a black layer at the TiN/nitrided layer interface was observed in all coatings deposited over nitrided layers produced above the threshold nitriding potential curves. This layer affects adversely the wear resistance and the adhesion of the TiN coatings. When higher loads are applied on the coated surface, egg shell type flaws easily occur.

Zur Aufklärung der lokalen Magnetisierungs- und magnetischen Streufeldstruktur in ferromagnetischen und supraleitenden Materialien wurden magnetkraftmikroskopische (Magnetkraftmikroskopie-MFM) Untersuchungen durchgeführt und quantitativ ausgewertet. Für eine solch quantitative Auswertung muss der Einfluß der verwendeten MFM-Spitzen auf das MFM-Bild bestimmt und in geeigneter Weise subtrahiert werden. Hierzu wurden Spitzenkalibrierungsroutinen und ein Verfahren zur Entfaltung der gemessenen MFM-Daten implementiert, das auf der Wiener Dekonvolution basiert. Mit Hilfe dieser Prozedur können sowohl die räumliche Ausdehnung als auch die Größe der Streufelder direkt aus gemessenen MFM-Bildern bestimmt werden.
Gezeigt wurde diese Anwendung für die Durchmesserbestimmung von Blasendomänen in einer (Co/Pd)-Multilage und für die Bestimmung der temperaturabhängigen magnetischen Eindringtiefe in einem supraleitendem BaFe2(As0.24P0.76)2 Einkristall. Desweiteren konnte durch die Kombination von mikromagnetischen Rechnungen und der quantitativen MFM-Datenanalyse die Existenz einer dreidimensionalen Vortex-Struktur am Ende von Co48Fe52-Nanodrähten nachgewiesen
werden. Damit ist es gelungen die Tiefensensitivität der Magnetkraftmikroskopie erfolgreich in die Rekonstruktion der vermessenen Magnetisierungsstruktur einzubeziehen.

Full textAbstract:
YesThe estimation of Polycrystalline Diamond Compact (PDC) cutters wear has been an area of concern for the drilling industry for years now. The cutter's wear has been measured practically by pulling the bit out for evaluation at the surface. It is important to find the right time for tripping out as this helps to avoid the fishing job and reduces the operational cost significantly. The prediction of the drilling performance is based on the interaction of cutter and rock. Several authors focused on the cutter-rock interface but only a few researchers tried to model the wear of the PDC bit cutters. The aim of this research is to understand the relationships between the rate of penetration (ROP) and the drilling variables per each foot, and then determine the overall bit efficiency for the whole drilling operation. A new mathematical model is derived to predict the PDC bit performance by considering the factors that were already not taken into account. These factors include rock strength, bit design, and bit hydraulic. The model investigates the effect of these parameters to estimate the abrasive cutters wear on the inner and the outer bit cones by deriving modified equations to calculate the mechanical specific energy (MSE), torque, and depth of cut (DOC) as a function of effective blades (EB). The model is used to forecast the bit cutters wear conditions in four wells in the oil fields located in Libya, which were drilled with three different PDC's sizes. The model enables the results to be compared to the actual bit cutters wear measured for inner and outer cones. The results are found that are well in agreement with the actual field data obtained in bit records.

"Defining religion: Death and anxiety in an Afro-Brazilian cult." Tulane University, 1994.
Find full textAbstract:
This dissertation clarifies the anthropological concept of religion by crafting the most useful scientific definition. The first chapter illustrates the confusion surrounding this term, and argues that the comparative method of anthropology requires that this imprecision be removed. Reviewing the four types of definitions of religion extant in the literature--Content, Behavioral/Performative, Mental, and Functional--Chapter 1 concludes that the best definition will be a generative functional definition. The second chapter supports this conclusion by finding that an independent discipline, American constitutional law, has arrived at the same understanding Chapter 3 details the nature of definitions and the method of their proper construction, and uses these insights to define of religion based upon its function to alleviate death anxiety. Chapter 4 examines whether an inverse relationship between religiousness and death anxiety actually pertains, while Chapter 5 argues that the discerned relationship is not merely correlational, but in fact technically functional. The sixth chapter demonstrates the superior utility of the proposed definition as compared to content definitions by considering which generates better hypotheses about religious conversion The remaining chapters anticipate possible criticisms of the proposed definition. Perhaps because the highlighted inverse relationship is not supported unanimously by the empirical evidence, it is unsuitable for a definitional criterion. But Chapter 7 counters that imperfect results arise from a faulty methodological equation between personal religiousness and professions of institutional affiliation. To illustrate the independence of theisms and religiousness, instances of theistic nonreligions (superstitions, folktales) and nontheistic religions (political and scientific religions) are discussed The universality of the proposed definition could be more forcefully argued if the relationship between religiousness and death anxiety were tied to other human universals such as the psychobiological substratum of possession mediumship. Chapter 8 first shows that the most popular sociological interpretation of mediumship, that by I. M. Lewis, inadequately fits the data for Brazil. Chapter 9 supplements Lewis' model by linking mediumship to genetic talents for dissociation. Such links, if they exist, would serve as support for the underlying premises which predicted the results, and thereby the probable universality of the proposed definition of religionacase@tulane.edu

The objectives of this study were to examine the meaning of life and attitudes toward death for firefighters- in Kaohsiung County and City. A further investigation on their possible relationships between the demographic variables (age, working years, education level, marital status, religion) of firefighters, environmental variables (work-related injuries, work-related life-threatening events, colleagues’ work-related death, loss of family members experiences) and their views of meaning of life and attitudes toward death were performed. The research instruments were: 1. structured questionnaires surveys: “The Meaning of Life” questionnaires and “Death Attitude Profile-Revised, DAP-R”; 2. face-in-face interview in depth with 10 selected firefighters. The samples were using the firefighters from Kaohsiung County and City. 500 questionnaires were distributed and 443 effective questionnaires were received. SPSS 10.0 for Windows with the function of descriptive statistics, compare Means with T-test, one-way ANOVA ( Scheff´e test) and Canonical Correlations analysis were performed to analyse the collected data. The results were as follows： 1. In the aspect of meaning of life. a. Firefighters viewed life mainly on “Life control”. b. 51 to 60 years age group scored “Life control” subscale significantly higher than 31 to 40 years age group. c. With 21 to 30 working years firefighters scored “Life control”, “Sorrow and sufferings acceptance”, “Life purpose” and “Will to meaning” significantly higher than the 6 to 10 working years. d. Divorced and widow scored higher than the single in “Sorrow and sufferings acceptance” and “Life purpose” subscales. e. Buddhist scored significantly higher than the non-religion in “Life purpose” subscale. 2. In the aspect of attitudes toward death. a. Firefighters’ attitudes were mainly toward “death avoidance”. b. 41 to 50 years old firefighters scored significantly higher on “escape acceptance” and “death acceptance” than 20 to 40 years old. c. Firefighters who work for 21 to 30 years scored significantly higher in “approach acceptance”, “death avoidance” and “fear of death” than with 6 to 10 years. In subscale “death avoidance”, 11 to 20 working years scored significantly higher than the 6 to 10 years working years. 21 to 30 working years scored significantly higher in “escape acceptance” than less than 5 working years. d. Christian scored significantly higher in “approach acceptance” than Taoism and non-religion firefighters. The Buddhist scored significantly higher than non-religion firefighters. e. Without any experiences lost of family members scored significantly higher in “fear of death” and “death avoidance” than the one who had experienced the death of family members. 3. The views of meaning of life (life control, sorrow and sufferings acceptance, life purpose and will to meaning) were strongly associated with the attitudes towards death (approach acceptance, fear of death, escape acceptance, death avoidance). The suggestions to the authority and administrative department for future implications practice include: 1. emphasizing on the life-saving equipments, facilities and training; 2. participating the “Life Education “curriculum; 3. choose an own religion; 4. establishing the social life within the firefighters’ family members.
