Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico

Prastyani, Erina January 2022 (has links)
As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. The microstructural deformation features found in the shocked quartz do not form randomly, and their orientation provides a better understanding of the impact cratering process. At present, there are no studies of EBSD data analysis of shocked quartz from Chicxulub. We investigated six thin sections from two samples from the M0077A borehole in the lower peak ring of the Chicxulub impact crater, using the Scanning Electron Microscopy (SEM)-EBSD technique. Both samples consist of shocked granite, with a significant amount of quartz.  Therefore, this study investigates the crystallographic preferred orientation (CPO) of shocked quartz and predicts the seismic velocities and anisotropy, based on the EBSD data. We carried out the analysis of EBSD data by using the MATLAB-based MTEX toolbox that can perform CPO analysis from pole figure plots and the prediction of seismic properties of minerals based on the Voigt-Reuss-Hill effective medium method. Although acquiring the EBSD data from these samples is challenging, leading to the lack of data measured, we found out that the prediction of P wave seismic velocity is in good agreement with other recent studies conducted in the same area. The range of predicted P wave velocities is 5.5-6.5 km/s with anisotropy of 8-15%. The actual observed laboratory measurements and in-situ seismic measurements are considerably smaller than this velocity range because our calculations do not incorporate pores or take microcracks into account.  A likely explanation for the large variability of anisotropy in shocked quartz is the relatively few mapped grains with EBSD, which would influence the CPO and lead to high predicted seismic anisotropy. Considering a greaternumber of grains in the CPO analysis, the CPO is reduced, and seismic anisotropy becomes smaller.

Office environment, health and job satisfaction : an explorative study of office design's influence

Danielsson, Christina January 2005 (has links)
The present thesis investigates environmental factors impact on office employees. More specifically, it investigates: 1) perception and experience of office environments, 2) satisfaction with office environments, and 3) health status and job satisfaction in connection to office environment. It is based on an empirical study with 491 office employees from twenty-six companies and divisions in larger companies. Each one respectively represents one of seven identified office-types in office design: cell-office, sharedroom office, small open plan office, medium open plan office, large open plan office, flex-office and combi-office. This study takes its basis in architecture, although an interdisciplinary approach from organizational and management theory, environmental psychology, and social and stress medicine has been used. Qualitative and quantitative methods were used. In Article I a review of the different research fields that investigate environmental influences are presented with a focus on office environments. Different perspectives on the environmental impact on office employees are investigated. In Article II an analysis of office environment based on the employee’s perception and experience of the architecture is done based on in-depth interviews using a method originally developed by Kevin Lynch (1960). The method measures the "imagebility" of a space, rated by the users with following elements: landmark, node, path, edge and district. The result showed that the method, based on employees’ perception and use of space, is a possible tool in the design process to get a better understanding of where the elements that reinforce "imageability" most likely will appear in an office environment. The method thus gives a better idea of the future "imageability" of a space and could be useful as guidance in the design process of how the architectural design will be received by the users in the end. In Article III employees’ satisfaction with the office environment in different office-types is investigated. The article focuses on three domains: 1) Ambient factors, 2) Noise and Privacy and 3) Designrelated factors. The statistical analysis was done using a logistic regression model with multivariate analysis. Adjustment was done for: age, gender, job rank, job satisfaction and market division. The results show differences in satisfaction with the office environment between employees in different office-types, many of which were statistically significant. When differences persist in the multivariate analysis they can possibly be ascribed to the office-type. Results show that employees in cell-offices are prominently most satisfied followed by those in flex-offices. Cell-offices rate only low on social aspects of Design-related factors. A major finding is internal differences between different office-types where employees share workspace and facilities. The medium and large open plan offices could be described as high-risk officetypes. In Article IV differences between employees in different office-types with regard to health, wellbeing and job satisfaction are analyzed. A multivariate analysis of the data was done with adjustment for the confounders: age, gender, job rank and market division. The results show that there are risks of ill health and poor well-being in medium and small open plan offices. Employees in these office-types show significantly higher risks compared with those in other office-types. In medium open plan and combioffices the employees show the highest prevalence of low job satisfaction. The best chance for good health status and job satisfaction is among employees in cell-offices and flex-offices; there are, however, internal differences in distribution on different outcome variables for job satisfaction. The major finding of these studies is that there are significant differences with regard to satisfaction with office environments as well as health status and job satisfaction between employees in different office-types; differences that can possibly can be ascribed to the office-types as they persist after adjustment for important confounders. / QC 20101126

Privaatheidsaspekte van strafprosessuele beskerming teen onreëlmatige voorverhoor-owerheidsoptrede

Steyn, Anna Sophia 30 November 2004 (has links)
Text in Afrikaans / Infringement, by the executive, of the right to privacy of the individual is an everyday occurrence. Section 14 of the Constitution, Act 108 of 1996 protects the right to privacy. The Criminal Procedure Act, Act 51 of 1977 authorises the police service, to search for and seize articles, to enter premises, ascertain bodily features of accused and to employ traps and undercover operations. On the one hand the Criminal Procedure Act authorises the police to infringe the privacy of the individual but on the other hand it guarantees the privacy of the individual. The provisions of the Criminal Procedure Act are qualified by the Constitution, specifically by section 36 and 35(5). The authorisation of a police officer should be obtained before a person could be arrested without a warrant, which should, in any event, be the last resort. The written permission of an officer must be obtained prior to the making of an application for a warrant to a magistrate. A police officer should be prohibited from issuing a search warrant, as the general perception of the public is that members of the police may not be sufficiently independent. The exercising of magistrates' discretion regarding the decision as to whether a search warrant should be issued or not should be extended. A search warrant should comply with strict requirements as to who may execute the warrant, when, how and when the warrant will become invalid. Search and seizure without a warrant should not be allowed at all, except in circumstances where there is an immediate threat or danger to a person, property or the public safety. In cases of urgency, it should be made possible to obtain the telephonic permission from a magistrate to search property. Where necessary to ascertain the bodily features of an accused through surgery, a compulsory application in terms of section 37(3) should be made to the court for authorisation, irrespective of whether the accused consents to the surgery or not. More importance should be attached to the rights of the individual and the powers of the executive should be limited. / Jurisprudence / LL.D

'Fines' : bordering practices and natural features in Livy

Montesanti, Antonio January 2014 (has links)
The fullest and most comprehensive unpacking of the term finis has yet to be achieved. Studies have narrowly focussed on the idea of border, boundary or frontier, without even entertaining the prospect of interpreting the study from the ancient point of view. This investigation considers the use of the word finis in Livy and attempts to recreate a conception of finis which mirrors as closely as possible that of a Roman of the Republic up to the very Early Empire. Besides the remarkably high usage of the term by Livy, the author’s work is also useful due to its chronological nature, which allows for broad investigation throughout the Republican Period, as well as shedding light on the Early Imperial concept of finis. The main aim of this dissertation is to provide a collective analysis of diverse cases, which together can help build a complete picture of the detectable features related to the term finis. As well as this, the analysis of the contexts – in which the term finis is used has also cast light on those features of finis – that have remained fixed despite the different historical contexts in which they appear. For example, throughout my study, two fundamental concepts will continue to pop up in front of the reader’s eyes: a) the inapplicability of modern conceptual categories to the idea of finis and b) finis – if translated as border, boundary or frontier – as a concept applicable not to a line, but to a spatial element. On the basis of Livy’s evidence – drawn from his work Ab Urbe Condita – this study attempts to present a reconstruction of the term through the identification of an entirely new concept. This study is conceived in terms of a crescendo, which begins with the basic definitions attached to finis and evolves, adding an increasing number of evidences until it reaches a climax, whereby the reader can see both those invariable features of finis in Livy’s account and the 4 Introduction: Research guidelines evolution of the term as fines are applied within different political contexts. Rome – a city that rose on a finis, the Tiber River – reinvented or remodelled the concept of finis, demonstrating behaviour antithetical to the notion of confining herself behind a ‘single line’. Once identified as a finis, the natural features helped the Romans to exert their imperium, which was itself an embodiment of the features contained within the concept of finis. The establishment of the fines provided an ‘imaginary’ subdivision of the territory subjected to the Roman imperium in a series of land strips. This is documented by Livy through Rome’s expansionist ‘finis-system’, from a single occupation of the Janiculum Hill to the scientific approach and setting of the treaty of Apamea. Although the lacunae in Ab Urbe Condita – from 168 B.C. onwards – do not permit a direct connection between the Late Republic and the Early Empire, some elements can be used to evidence an intimate relationship between Livy’s and Augustus’ thinking and terminology. To some extent, this common intent has made possible this attempted reconstruction of the ‘bordering practices’ used in the last 150 years of the Republic, as well as the possible evolution of such practices in the first 150 about years of the Empire.

Highly automated method for facial expression synthesis

Ersotelos, Nikolaos January 2010 (has links)
The synthesis of realistic facial expressions has been an unexplored area for computer graphics scientists. Over the last three decades, several different construction methods have been formulated in order to obtain natural graphic results. Despite these advancements, though, current techniques still require costly resources, heavy user intervention and specific training and outcomes are still not completely realistic. This thesis, therefore, aims to achieve an automated synthesis that will produce realistic facial expressions at a low cost. This thesis, proposes a highly automated approach for achieving a realistic facial expression synthesis, which allows for enhanced performance in speed (3 minutes processing time maximum) and quality with a minimum of user intervention. It will also demonstrate a highly technical and automated method of facial feature detection, by allowing users to obtain their desired facial expression synthesis with minimal physical input. Moreover, it will describe a novel approach to the normalization of the illumination settings values between source and target images, thereby allowing the algorithm to work accurately, even in different lighting conditions. Finally, we will present the results obtained from the proposed techniques, together with our conclusions, at the end of the paper.

3D facial feature extraction and recognition : an investigation of 3D face recognition : correction and normalisation of the facial data, extraction of facial features and classification using machine learning techniques

Al-Qatawneh, Sokyna M. S. January 2010 (has links)
Face recognition research using automatic or semi-automatic techniques has emerged over the last two decades. One reason for growing interest in this topic is the wide range of possible applications for face recognition systems. Another reason is the emergence of affordable hardware, supporting digital photography and video, which have made the acquisition of high-quality and high resolution 2D images much more ubiquitous. However, 2D recognition systems are sensitive to subject pose and illumination variations and 3D face recognition which is not directly affected by such environmental changes, could be used alone, or in combination with 2D recognition. Recently with the development of more affordable 3D acquisition systems and the availability of 3D face databases, 3D face recognition has been attracting interest to tackle the limitations in performance of most existing 2D systems. In this research, we introduce a robust automated 3D Face recognition system that implements 3D data of faces with different facial expressions, hair, shoulders, clothing, etc., extracts features for discrimination and uses machine learning techniques to make the final decision. A novel system for automatic processing for 3D facial data has been implemented using multi stage architecture; in a pre-processing and registration stage the data was standardized, spikes were removed, holes were filled and the face area was extracted. Then the nose region, which is relatively more rigid than other facial regions in an anatomical sense, was automatically located and analysed by computing the precise location of the symmetry plane. Then useful facial features and a set of effective 3D curves were extracted. Finally, the recognition and matching stage was implemented by using cascade correlation neural networks and support vector machine for classification, and the nearest neighbour algorithms for matching. It is worth noting that the FRGC data set is the most challenging data set available supporting research on 3D face recognition and machine learning techniques are widely recognised as appropriate and efficient classification methods.

An investigation into the accident causal influence of construction project features

Manu, Patrick Ackom January 2012 (has links)
The United Kingdom (UK) construction industry is one of the worst industries in the UK in terms of health and safety (H&S) performance. Numerous injuries, deaths, dangerous occurrences and work related illnesses are reported annually in the industry, and these are associated with huge economic and social costs which make the need for H&S improvement inevitable. The pursuit of improvement has triggered studies into construction accident causation which have emphasised the need to pay attention to underlying accident causal factors which emanate from the pre-construction stage in order to have sustained improvement in H&S. Construction project features (CPFs), such as nature of project, method of construction, site restriction, procurement method, project duration, level of construction, design complexity, and subcontracting, which are organisational, physical, and operational characteristics of projects emanating from pre-construction decisions fall in this category of underlying causal factors. However, despite the significance of underlying causal factors to H&S, not much attention by way of research has been given to CPFs. As a result, insight into how CPFs influence accident occurrence, the degree of their inherent potential to influence accident occurrence (i.e. their potential to cause accident) and their associated degree of H&S risk (i.e. the likelihood of accident occurrence due to CPFs) remain elusive in the extant construction H&S literature. This research was thus undertaken to empirically investigate the mechanism by which CPFs influence accident occurrence and assess their degree of potential to influence accident occurrence and their associated H&S risk. Adopting a mixed method approach, the accident causal influence of CPFs was investigated. Following a conceptualisation of how CPFs influence accident occurrence based on systems models of accident causation, a qualitative inquiry involving semi-structured interviews with experienced construction professionals was undertaken to provide empirical verification of the conceptualised view. Subsequent to the qualitative inquiry, a questionnaire survey was undertaken to elicit relevant data from experienced professionals in construction management roles to enable the assessment of the degree of potential of CPFs to influence accident occurrence and their associated H&S risk. From the analysis of data, it was found that CPFs, emanating from pre-construction decisions, influence accident occurrence by their inherent introduction of certain associated H&S issues (which can be termed as proximal accident factors) into the construction phase of projects to give rise to accidents. There are also causal interactions between CPFs and the proximal factors which can reduce or increase the presence of proximal factors. CPFs have varying degrees of potential to influence accident occurrence which can generally be high or moderate and is influenced by: the extent to which their proximal factor(s) is common (in other words prevalent) within them; and the degree of potential of the proximal factor(s) to influence accident occurrence. Where CPFs apply on a project, they are generally associated with medium risk or high risk. Whereas with medium-risk CPFs some risk control measures would suffice in mitigating risk, with high-risk CPFs substantial measures are required. As a consolidation of the research findings, a toolkit, called CRiMT, has been developed. CRiMT provides H&S risk information regarding CPFs and it has the potential of assisting pre-construction project participants in managing the accident causal influence of CPFs from the early stage of project procurement. In view of the findings, the accident causal influence of CPFs should thus not be ignored or underestimated in construction project delivery. Pre-construction project participants, especially those whose decisions determine CPFs, ought to take into consideration the H&S effects of CPFs when making decisions which determine CPFs. Also, pre-construction project participants ought to plan and implement commensurate risk control measures in the early stage of projects to eliminate or mitigate the H&S risk posed by CPFs.

The Internationalization of Family Firms : Facilitating and Constraining Features

Koopman, Martin, Sebel, Kevin January 2009 (has links)
<p><strong>Introduction:</strong> Research has shown that family firms play an important role in modern economies and that they maintain special characteristics and features in comparison to non-family businesses. Furthermore, it is evident in literature and practice that internationalization is a crucial process and strategy in the present global business environment.</p><p><strong>Problem:</strong> These findings however, have not led to a family business internationalization strategy. Only some studies have been conducted concerning the influence of the special features of family firms on the process of internationalization. This means that there is a gap between theory and practice.</p><p><strong>Purpose:</strong> To increase the academic understanding of the phenomenon internationalization of family businesses, through the use of both theoretical and empirical findings.</p><p><strong>Research questions:</strong> This study attempted to fulfill the purpose by providing answers to several research questions. The main research questions are: What is the current state of knowledge about internationalization, family business features and previous research in internationalization of family firms? How do the family business features theoretically influence the internationalization process? How do the family business features empirically influence the internationalization process? What are the theoretical contributions and practical managerial implications of these findings?</p><p><strong>Method:</strong> A solid literature research has been conducted in order to determine the theoretical influences of family business features on internationalization. The empirical testing of the expectations was conducted through a qualitative approach by taking personal interviews at eight companies, four in The Netherlands and four in Sweden, and studying secondary documentation.</p><p><strong>Findings:</strong> The study shows that it is difficult to decisively determine the either facilitating or constraining influence of family business features on internationalization. The results show that the 23 features which have been studied in the sample are facilitating or constraining under certain conditions (see table 5, p. 108). This implies that managers, researchers and consultants will be required to study these conditions first in order to determine the facilitating or constraining effects in a company. In addition, a model has been constructed illustrating the empirical findings concerning the internationalization process (see figure 8, p.112). Finally, concerning internationalization theories, it is determined that family businesses tend to use the Network approach in starting their internationalization process, the Stage approaches in further developing the international operations and support their process through the Resource-based view and the Knowledge-based view.</p>
