Abstract:
Magister Chirurgiae Dentium - MChD (Maxillo-Facial & Oral Surgery)
South African dentists have a legal and ethical obligation to maintain complete and comprehensive dental records. In addition to the legal and ethical requirements, dental records are also important in the case of medico-legal issues, quality assurance processes and forensic purposes. Valuable forensic evidence contained in dental records are used in the identification of victims of mass disasters, personal victim identification e.g. in severely decomposed or skeletonized remains where DNA or other biometric data are not available. The victim identification process is highly dependent on complete, legible and accurate dental records. A review of the literature however shows that dental record keeping practices are sub-optimal worldwide. There is a paucity of studies in South Africa regards to dental record keeping practices. The aim of this study was to assess the record keeping practices of a sample of private practicing dentists in Cape Town and surrounding towns, for forensic dental purposes. Knowledge and awareness regards to forensic odontology as well as adherence to the guidelines prescribed by the Health Professional Council of South Africa were also assessed. This was a cross-sectional descriptive study, employing a researcher-administered questionnaire and a dental checklist for forensic valuable items in the dental file. The results were entered in a MS Excel spreadsheet and statistically analysed using IMB SPSS Statistics. This study concluded that most of the dental records kept by Cape Town dentists are near to optimal and would be helpful during forensic odontology investigations. However, shortcomings in record keeping practices exists which may compromise the forensic accuracy of their dental records. The study also shows a significant difference in dental record keeping practices by dentists practicing in lower income areas in Cape Town, compared to those practicing in economic affluent areas. The dentists in this study adhered to most of the guidelines prescribed by the Health Professional Council of South Africa however, important medico-legal information was missing from most dental records. This study hopes to contribute to future comprehensive studies in the broader South Africa to determine the validity of dental records for forensic odontology purposes.

Abstract:
Abstract. The quality assessment of signal has been a research topic for many years, as it is mainly related to the problem of the false alarms. Automatic quality detection/assessment and classification of signals can play a vital role in the development of robust unsupervised electrocardiogram (ECG). The development of efficient algorithms for the quality control of ECG recordings is essential to improve healthcare now. ECG signal can be intermixed with many kinds of unwanted noises. It is an important task to assess the quality of the ECG signal for further biomedical inspections. To make that happen, we made an algorithm that is efficient and uses some basic quality features to classify the ECG signals. It is a very effective way to acquire a good quality ECG signal in real-time by unskilled personnel for instance in rural areas there is not enough expertise in this field. By using this method, they can quickly know if the ECG signal is acceptable or unacceptable for further inspections. The method is used to assess the quality of the ECG signals in the training set of the Physionet/Computing in Cardiology Challenge 2011, giving a correct interpretation of the quality of the ECG signals of 93.08% which corresponded to a sensitivity of 96.53% and a specificity of 86.76%.

Abstract:
The provision of high quality data is of considerable importance to both business and government; poor data may lead to poor decisions, so quality plays a crucial role. With the proliferation of electronic data collection by businesses and governments, there has arisen a pressing need to assure this quality. This has been recognized by both the private and public sectors, and many initiatives such as the Data Quality Initiative Framework by the Welsh government, passed in 2004, and the Data Quality Act by the United States government, passed in 2002, have been launched to improve it in those countries. At the same time, healthcare is a domain in which the timely provision of accurate, current and complete patient data is one of the most important objectives. Instigation of a so-called Electronic Health Record (EHR), defined as a repository of patient data in digital form that is stored and exchanged securely and is accessible by different levels of authorized users, has been attracting the attention of both research and industry. EHRs allow information regarding a patient’s health to be distributed among heterogeneous information systems. This evolution has added a layer of complexity in data quality, making data quality assurance a challenging issue, as the key barriers to optimal use of EHR data are the increasing quantity of data and their poor quality. Many data quality frameworks have been developed to measure the quality of data in information systems. However, there is no consensus on a rigorously defined set of data quality dimensions. Existing dimensions are usually based on literature reviews, industrial experiences or intuitive understanding and do not take into consideration the nature of e-healthcare systems. Moreover, definitions of these dimensions vary from one data quality framework to another. The aim of this research is to develop a data quality framework consisting of health-relevant dimensions, and data quality measures that help health organisations to enhance the quality of their data. The study provides both subjective and objective measures for assessing the quality of data. An 11-dimensional data quality framework has been developed and confirmed by EHR stakeholders and a group of experts and data consumers. With each dimension, several associated measures have been developed to help an organisation to measure the quality of the data populating their EHR systems. Some issues linked with the measures associated with security-related dimensions have arisen during the confirmation stage. Therefore, these issues were further discussed and reviewed with security experts in order to revise the proposed framework and its measures. Subsequently, a case study was conducted in a large hospital to examine the practicality of the proposed instrument. The instrument was used to help hospitals to assess their data. After that, the usefulness and practicality of the instrument were examined through an evaluation questionnaire distributed to quality assessment team members. Follow-up interviews with senior managers were carried out to discuss the output of the assessment and its practicality. The contribution of this research is the development of a proper data quality framework for EHRs in the context of Saudi Arabia which resulted in 11 health-relevant data quality dimensions. An instrument was also introduced to represent all developed and confirmed measures that assess data population in EHRs.

Abstract:
Hominins (the clade including modern humans and their fossil ancestors) were a taxonomically and morphologically diverse group during the Plio-Pleistocene, and their evolution documents the only known transition to obligate bipedalism in primates. However,many aspects of their shared evolutionary history remain frustratingly unclear due to uncertainty about whether change in the fossil record reflects genuine evolutionary change or variation in our sampling of the rock record. Here, a comprehensive assessment of the quality of the early African hominin fossil record is presented. A specimen database of all early African hominin fossils (>5000) has been compiled including taxonomic, geological, anatomical, and bibliographic information. Using a range of sampling metrics (fossil-bearing formations, collection effort, sampled area, and ghost lineage diversity), it is shown that the pulsedlike pattern of uncorrected (taxic) hominin diversity is almost entirely controlled by rock availability. By contrasting taxic with phylogenetically corrected diversity, hominin diversification appears unconstrained through the lateMiocene and Pliocene, with diversity constantly increasing until a single peak is reached in the early Pleistocene. Phylogenetically corrected diversity shows no discernible link with sampling metrics and there is no direct evidence that shifts in climatic conditions drove diversification. A study of specimen completeness through geological time shows that while sampling metrics (specifically sustained collection effort at rich deposits) have a major influence on patterns of specimen completeness, specimen completeness has only a moderate influence on diversity patterns. It also shows that specimen completeness is poorest during the period most pertinent to human origins, the estimated Pan-Homo divergence date, in large part due to under-sampling (< 4% of Africa by sampled area). In combination, this work illustrates that the hominin fossil record is by no means an unbiased depiction of evolutionary events, and therefore its quality and incompleteness should be fully understood before any interpretation of macroevolutionary patterns.

Whittle, Joss. "Quality assessment and variance reduction in Monte Carlo rendering algorithms." Thesis, Swansea University, 2018. https://cronfa.swan.ac.uk/Record/cronfa40271.

Full text
Abstract:
Over the past few decades much work has been focused on the area of physically based rendering which attempts to produce images that are indistinguishable from natural images such as photographs. Physically based rendering algorithms simulate the complex interactions of light with physically based material, light source, and camera models by structuring it as complex high dimensional integrals [Kaj86] which do not have a closed form solution. Stochastic processes such as Monte Carlo methods can be structured to approximate the expectation of these integrals, producing algorithms which converge to the true rendering solution as the amount of computation is increased in the limit. When a finite amount of computation is used to approximate the rendering solution, images will contain undesirable distortions in the form of noise from under-sampling in image regions with complex light interactions. An important aspect of developing algorithms in this domain is to have a means of accurately comparing and contrasting the relative performance gains between different approaches. Image Quality Assessment (IQA) measures provide a way of condensing the high dimensionality of image data to a single scalar value which can be used as a representative measure of image quality and fidelity. These measures are largely developed in the context of image datasets containing natural images (photographs) coupled with their synthetically distorted versions, and quality assessment scores given by human observers under controlled viewing conditions. Inference using these measures therefore relies on whether the synthetic distortions used to develop the IQA measures are representative of the natural distortions that will be seen in images from domain being assessed. When we consider images generated through stochastic rendering processes, the structure of visible distortions that are present in un-converged images is highly complex and spatially varying based on lighting and scene composition. In this domain the simple synthetic distortions used commonly to train and evaluate IQA measures are not representative of the complex natural distortions from the rendering process. This raises a question of how robust IQA measures are when applied to physically based rendered images. In this thesis we summarize the classical and recent works in the area of physicallybased rendering using stochastic approaches such as Monte Carlo methods. We develop a modern C++ framework wrapping MPI for managing and running code on large scale distributed computing environments. With this framework we use high performance computing to generate a dataset of Monte Carlo images. From this we provide a study on the effectiveness of modern and classical IQA measures and their robustness when evaluating images generated through stochastic rendering processes. Finally, we build on the strengths of these IQA measures and apply modern deep-learning methods to the No Reference IQA problem, where we wish to assess the quality of a rendered image without knowing its true value.

Abstract:
Abstract. Photo retouching can significantly improve image quality and it is considered an essential part of photography. Traditionally this task has been completed manually with special image enhancement software. However, recent research utilizing neural networks has been proven to perform better in the automated image enhancement task compared to traditional methods. During the literature review of this thesis, multiple automatic neural-network-based image enhancement methods were studied, and one of these methods was chosen for closer examination and evaluation. The chosen network design has several appealing qualities such as the ability to learn both local and global enhancements, and its simple architecture constructed for efficient computational speed. This research proposes a novel dataset generation method for automated image enhancement research, and tests its usefulness with the chosen network design. This dataset generation method simulates commonly occurring photographic errors, and the original high-quality images can be used as the target data. This dataset design allows studying fixes for individual and combined aberrations. The underlying idea of this design choice is that the network would learn to fix these aberrations while producing aesthetically pleasing and consistent results. The quantitative evaluation proved that the network can learn to counter these errors, and with greater effort, it could also learn to enhance all of these aspects simultaneously. Additionally, the network’s capability of learning local and portrait specific enhancement tasks were evaluated. The models can apply the effect successfully, but the results did not gain the same level of accuracy as with global enhancement tasks. According to the completed qualitative survey, the images enhanced by the proposed general enhancement model can successfully enhance the image quality, and it can perform better than some of the state-of-the-art image enhancement methods.Automaattinen kuvanlaadun parantaminen käyttämällä syviä neuroverkkoja. Tiivistelmä. Manuaalinen valokuvien käsittely voi parantaa kuvanlaatua huomattavasti ja sitä pidetään oleellisena osana valokuvausprosessia. Perinteisesti tätä tehtävää varten on käytetty erityisiä manuaalisesti operoitavia kuvankäsittelyohjelmia. Nykytutkimus on kuitenkin todistanut neuroverkkojen paremmuuden automaattisessa kuvanparannussovelluksissa perinteisiin menetelmiin verrattuna. Tämän diplomityön kirjallisuuskatsauksessa tutkittiin useita neuroverkkopohjaisia kuvanparannusmenetelmiä, ja yksi näistä valittiin tarkempaa tutkimusta ja arviointia varten. Valitulla verkkomallilla on useita vetoavia ominaisuuksia, kuten paikallisten sekä globaalien kuvanparannusten oppiminen ja sen yksinkertaistettu arkkitehtuuri, joka on rakennettu tehokasta suoritusnopeutta varten. Tämä tutkimus esittää uuden opetusdatan generointimenetelmän automaattisia kuvanparannusmetodeja varten, ja testaa sen soveltuvuutta käyttämällä valittua neuroverkkorakennetta. Tämä opetusdatan generointimenetelmä simuloi usein esiintyviä valokuvauksellisia virheitä, ja alkuperäisiä korkealaatuisia kuvia voi käyttää opetuksen tavoitedatana. Tämän generointitavan avulla voitiin tutkia erillisten valokuvausvirheiden, sekä näiden yhdistelmän korjausta. Tämän menetelmän tarkoitus oli opettaa verkkoa korjaamaan erilaisia virheitä sekä tuottamaan esteettisesti miellyttäviä ja yhtenäisiä tuloksia. Kvalitatiivinen arviointi todisti, että käytetty neuroverkko kykenee oppimaan erillisiä korjauksia näille virheille. Neuroverkko pystyy oppimaan myös mallin, joka korjaa kaikkia ennalta määrättyjä virheitä samanaikaisesti, mutta alhaisemmalla tarkkuudella. Lisäksi neuroverkon kyvykkyyttä oppia paikallisia muotokuvakohtaisia kuvanparannuksia arvioitiin. Koulutetut mallit pystyvät myös toteuttamaan paikallisen kuvanparannuksen onnistuneesti, mutta nämä mallit eivät yltäneet globaalien parannusten tasolle. Toteutetun kyselytutkimuksen mukaan esitetty yleisen kuvanparannuksen malli pystyy parantamaan kuvanlaatua onnistuneesti, sekä tuottaa parempia tuloksia kuin osa vertailluista kuvanparannustekniikoista.

Full text
Abstract:
Synapsiden erscheinen erstmals im Fossilbericht im Oberkarbon (späten Pennsylvanium) und dominierten terrestrische Ökosysteme bis zum Ende des Paläozoikums. Diese Arbeit ist die erste detaillierte Betrachtung der frühen Evolution der Synapsiden. Modifizierte Versionen zuvor publizierter Vollständigkeitsmaße werden benutzt, um die Vollständigkeit von Pelycosaurier Fossilien einzuschätzen. Zudem wird eine Reihe unterschiedlicher Methoden genutzt, um die Übereinstimmung von Fossilbericht und Phylogenese zu messen. Die Vollständigkeitsanalyse der Pelycosaurier zeigt eine negative Korrelation zwischen Diversität und dem Maß der Merkmalsvollständigkeit, was darauf hindeutet, dass viele Spezies auf unvollständig erhaltenem Material basieren. Die fehlende Korrelation zwischen dem Maß zur Merkmalsvollständigkeit (basierend auf Abschätzung der Proportion phylogenetisch erfassbarer Merkmale) und der Diversität wird auf die Entdeckungsgeschichte der Gruppe zurück geführt: Die Mehrheit der Pelycosaurier-Arten wurden zwischen den 1930er und 1960er Jahren benannt, als taxonomische Zuordnungen häufig auf Körpergrösse, Fundort und Stratigraphie anstatt auf morphologischen Merkmalen basierten. Welche Schätzungen der Artenzahl über die Erdgeschichte beinflussen, produzieren die unterschiedlichen Methoden zur Diversitätsrekonstruktion sehr ähnliche Ergebnisse. Der initialen Diversifikation der Synapsiden im Oberkarbon und Unterperm (frühes Cisuralium) folgte ein Aussterbeereignis während des Sakmariums. Ein zweites Aussterben ereignete sich an der Grenze vom Kungurium zum Roadium. Die phylogenetisch Topologie-Analyse keine signifikanten Steigerungen der Diversitätsrate der Pelycosaurier relativ zu zeitgleich lebenden Taxa. Eine breiter angelegte Auswertung der Diversitätsentwicklung paläozoischer und triassischer Amnioten liefert ein mögliches Erklärungsmodell; Veränderungen der Diversitätsraten früher Amnioten tendieren dazu, zu Zeiten erhöhter Aussterberaten aufzutreten.
Synapsids first appear in the fossil record during the late Pennsylvanian, and dominated the terrestrial realm until the end of the Palaeozoic. This thesis provides the first detailed examination of the earliest evolution of synapsids. Modifications of previously published metrics are used to assess the completeness of their specimens, and a variety of methods are employed to measure the fit of the fossil record to the phylogeny. The analysis into the completeness of pelycosaurian-grade specimens reveals a negative correlation between diversity and the Skeletal Completeness Metric, assessing the bulk of material preserved, suggesting a tendency to name many species based on poor material. The lack of correlation between the Character Completeness Metric (assessing the proportion of phylogenetic characters that can be scored) and diversity is attributed to the history of discovery in the group: the majority of pelycosaurian-grade species were named between the 1930s and 1960s, when assignments were often based on size, location and stratigraphy rather than morphological characters. The different methods of assessing diversity provide very similar results. The initial diversification of synapsids in the Late Pennsylvanian and early Cisuralian was followed by an extinction event during the Sakmarian. A second extinction event occurred across the Kungurian/Roadian boundary. The tree topology analysis found no significant increases in diversification rate occurring in pelycosaurian-grade taxa relative to their contemporaries. A broader examination of diversification patterns in Palaeozoic and Triassic amniotes reveals a possible explanation; diversification rate shifts within early amniotes tend to occur during periods of elevated extinction.

Saunders, Paul. "Examination of the factors affecting quality on continuous annealing processing lines." Thesis, Swansea University, 2008. https://cronfa.swan.ac.uk/Record/cronfa42366.

Full text
Abstract:
The Continuous Annealing Processing Line (CAPL) of the Corus Strip Products UK integrated works in South Wales, United Kingdom, is one of the most modern lines of its type in the world. It produces thin and wide carbon strip steels of the highest quality in terms of metallurgical consistency, surface quality and dimensional tolerances. Tensioned strip can travel at a velocity of up to 600m/min at temperatures in excess of 750°C. The yield point of the strip is naturally reduced at these annealing temperatures; therefore the contact interaction that develops between the transport roll and the strip steel it is transporting is critical. The primary focus of research is on maintaining the elasticity of the strip steel as it passes through the furnace section of the continuous annealing processing line. In particular focusing on the heating and adjacent soaking sections of the CAPL, where the temperatures are at their highest. The thesis is concerned with the roll-strip interaction and its many different parameters - roll geometry, strip dimensions, strip tension and strip temperature. Research concentrated on the initial contact plane, where the strip first comes into contact with the transport roll. Results indicate that the strip's elastic stress- state is most affected by the fillet that circumnavigates the transport roll, especially where the fillet intersects the initial contact plane. The parameters chosen took into consideration the future operational commitments of the CAPL, because continual demand is always increasing the threshold. To perform the task assigned the author made use of extensive computational finite element method models. A second aspect of the research was to consider acceptable temperature differentials between the transport roll and the strip steel at initial contact. The strip has a low yield stress at its annealing temperature, thus an excessively high temperature differential will create a buckle risk. Therefore, an experimental programme was developed in conjunction with industrial partners Stein Heurtey to investigate acceptable temperature differentials for initial contact conditions.

Abstract:
Cultural heritage institutions, including galleries, libraries, museums, and archives are increasingly digitizing physical items and collecting born-digital items and making these resources available on the Web. Metadata plays a vital role in the discovery and management of these collections. Existing frameworks to identify and address deficiencies in metadata rely heavily on count and data-value based metrics that are calculated over aggregations of descriptive metadata. There has been little research into the use of traditional network analysis to investigate the connections between metadata records based on shared data values in metadata fields such as subject or creator. This study introduces metadata record graphs as a mechanism to generate network-based statistics to support analysis of metadata. These graphs are constructed with the metadata records as the nodes and shared metadata field values as the edges in the network. By analyzing metadata record graphs with algorithms and tools common to the field of network analysis, metadata managers can develop a new understanding of their metadata that is often impossible to generate from count and data-value based statistics alone. This study tested application of metadata record graphs to analysis of metadata collections of increasing size, complexity, and interconnectedness in a series of three related stages. The findings of this research indicate effectiveness of this new method, identify network algorithms that are useful for analyzing descriptive metadata and suggest methods and practices for future implementations of this technique.

Abstract:
基於審美的圖像質量自動評估近年來引起了計算機視覺領域的普遍關注。在這篇論文裡, 我們提出使用局部與整體特徵, 基於圖像內容進行圖片質量評估。首先, 圖像的主題區域被提取出來。這部分區域最吸引觀看者的注意力。基於主題區域, 我們提取局部特徵, 並結合整體特徵進行圖像質量評估。攝影專家拍攝圖片時, 對於不同內容的圖片, 會採取不同的技術手段和審美衡量標準。基於此項觀察, 我們提出根據圖片的內容, 在提取主題區域以及特徵的時候採用不同的手段。我們講數據根據圖像內容分為七類, 並分別設計主題區域提取方法和設計特徵。我們通過翔實的實驗數據,證明提出的框架之有效。
同時, 我們提出根據圖像內容特徵構建自適應分類器, 以在不事先知道圖像內容分類的情況下進行自動質量評估, 並取得滿意效果。
Automatically assessing photo quality from the perspective of visual aesthetics is of great interest in high-level vision research and has drawn much attention in recent years. In this paper, we propose content-based photo quality assessment using both regional and global features. Under this framework, subject areas, which draw the most attentions of human eyes, are first extracted. Then regional features extracted both from subject areas and background regions are combined with global features to assess photo quality. Since professional photographers adopt different photographic techniques and have different aesthetic criteria in mind when taking different types of photos (e.g. landscape versus portrait), we propose to segment subject areas and extract visual features in different ways according to the variety of photo content. We divide the photos into seven categories based on the irvisual content and develop a set of new subject are a extraction methods and new visual features specially designed for different categories.
This argument is supported by extensive experimental comparisons of existing photo quality assessment approaches as well as our new features over different categories of photos. In addition, we propose an approach of online training an adaptive classifier to combine the proposed features according to the visual content of a test photo without knowing its category. Another contribution of this work is to construct a large and diversified benchmark database for the research of photo quality assessment. It includes 17, 613 photos with manually labeled ground truth. This new benchmark database will be released to the research community.

Abstract:
Record linkage refers to the task of finding and linking records (in a single database or in a set of data sources) that refer to the same entity. Automating the record linkage process is a challenging problem, and has been the topic of extensive research for many years. However, the changing nature of the linkage process and the growing size of data sources create new challenges for this task. This thesis studies the record linkage problem for Web data sources. Our hypothesis is that a generic and extensible set of linkage algorithms combined within an easy-to-use framework that integrates and allows tailoring and combining of these algorithms can be used to effectively link large collections of Web data from different domains. To this end, we first present a framework for record linkage over relational data, motivated by the fact that many Web data sources are powered by relational database engines. This framework is based on declarative specification of the linkage requirements by the user and allows linking records in many real-world scenarios. We present algorithms for translation of these requirements to queries that can run over a relational data source, potentially using a semantic knowledge base to enhance the accuracy of link discovery. Effective specification of requirements for linking records across multiple data sources requires understanding the schema of each source, identifying attributes that can be used for linkage, and their corresponding attributes in other sources. Schema or attribute matching is often done with the goal of aligning schemas, so attributes are matched if they play semantically related roles in their schemas. In contrast, we seek to find attributes that can be used to link records between data sources, which we refer to as linkage points. In this thesis, we define the notion of linkage points and present the first linkage point discovery algorithms. We then address the novel problem of how to publish Web data in a way that facilitates record linkage. We hypothesize that careful use of existing, curated Web sources (their data and structure) can guide the creation of conceptual models for semi-structured Web data that in turn facilitate record linkage with these curated sources. Our solution is an end-to-end framework for data transformation and publication, which includes novel algorithms for identification of entity types and their relationships out of semi-structured Web data. A highlight of this thesis is showcasing the application of the proposed algorithms and frameworks in real applications and publishing the results as high-quality data sources on the Web.
