Background: Body composition is affected by diseases, and affects responses to medical treatments, dosage of medicines, etc., while an abnormal body composition contributes to the causation of many chronic diseases. While we have reliable biochemical tests for certain nutritional parameters of body composition, such as iron or iodine status, and we have harnessed nuclear physics to estimate the body’s content of trace elements, the very basic quantification of body fat content and muscle mass remains highly problematic. Both body fat and muscle mass are vitally important, as they have opposing influences on chronic disease, but they have seldom been estimated as part of population health surveillance. Instead, most national surveys have merely reported BMI and waist, or sometimes the waist/hip ratio; these indices are convenient but do not have any specific biological meaning. Anthropometry offers a practical and inexpensive method for muscle and fat estimation in clinical and epidemiological settings; however, its use is imperfect due to many limitations, such as a shortage of reference data, misuse of terminology, unclear assumptions, and the absence of properly validated anthropometric equations. To date, anthropometric methods are not sensitive enough to detect muscle and fat loss. Aims: The aim of this thesis is to estimate Adipose/fat and muscle mass in health disease and during weight loss through; 1. evaluating and critiquing the literature, to identify the best-published prediction equations for adipose/fat and muscle mass estimation; 2. to derive and validate adipose tissue and muscle mass prediction equations; and 3.to evaluate the prediction equations along with anthropometric indices and the best equations retrieved from the literature in health, metabolic illness and during weight loss. Methods: a Systematic review using Cochrane Review method was used for reviewing muscle mass estimation papers that used MRI as the reference method. Fat mass estimation papers were critically reviewed. Mixed ethnic, age and body mass data that underwent whole body magnetic resonance imaging to quantify adipose tissue and muscle mass (dependent variable) and anthropometry (independent variable) were used in the derivation/validation analysis. Multiple regression and Bland-Altman plot were applied to evaluate the prediction equations. To determine how well the equations identify metabolic illness, English and Scottish health surveys were studied. Statistical analysis using multiple regression and binary logistic regression were applied to assess model fit and associations. Also, populations were divided into quintiles and relative risk was analysed. Finally, the prediction equations were evaluated by applying them to a pilot study of 10 subjects who underwent whole-body MRI, anthropometric measurements and muscle strength before and after weight loss to determine how well the equations identify adipose/fat mass and muscle mass change. Results: The estimation of fat mass has serious problems. Despite advances in technology and science, prediction equations for the estimation of fat mass depend on limited historical reference data and remain dependent upon assumptions that have not yet been properly validated for different population groups. Muscle mass does not have the same conceptual problems; however, its measurement is still problematic and reference data are scarce. The derivation and validation analysis in this thesis was satisfactory, compared to prediction equations in the literature they were similar or even better. Applying the prediction equations in metabolic illness and during weight loss presented an understanding on how well the equations identify metabolic illness showing significant associations with diabetes, hypertension, HbA1c and blood pressure. And moderate to high correlations with MRI-measured adipose tissue and muscle mass before and after weight loss. Conclusion: Adipose tissue mass and to an extent muscle mass can now be estimated for many purposes as population or groups means. However, these equations must not be used for assessing fatness and categorising individuals. Further exploration in different populations and health surveys would be valuable.

The stereographic projection is a bijective smooth map which allows us to think the sphere as the extended complex plane. Among its properties it should be emphasized the remarkable property of being angle conformal that is, it is an angle measure preserving map. Unfortunately, this projection map does not preserve areas. Besides being conformal it has also the property of projecting spherical circles in either circles or straight lines in the plane This type of projection maps seems to have been known since ancient times by Hipparchus (150 BC), being Ptolemy (AD 140) who, in his work entitled "The Planisphaerium", provided a detailed description of such a map. Nonetheless, it is worthwhile to mention that the property of the invariance of angle measure has only been established much later, in the seventeenth century, by Thomas Harriot. In fact, it was exactly in that century that the Jesuit François d’Aguilon introduced the terminology "stereographic projection" for this type of maps, which remained up to our days. Here, we shall show how we create in GeoGebra, the PRiemannz tool and its potential concerning the visualization and analysis of the properties of the stereographic projection, in addition to the viewing of the amazing relations between Möbius Transformations and stereographic projections.

POSTDATA is a 5 year's European Research Council (ERC) Starting Grant Project that started in May 2016 and is hosted by the Universidad Nacional de Educación a Distancia (UNED), Madrid, Spain. The context of the project is the corpora of European Poetry (EP), with a special focus on poetic materials from different languages and literary traditions. POSTDATA aims to offer a standardized model in the philological field and a metadata application profile (MAP) for EP in order to build a common classification of all these poetic materials. The information of Spanish, Italian and French repertoires will be published in the Linked Open Data (LOD) ecosystem. Later we expect to extend the model to include additional corpora. There are a number of Web Based Information Systems in Europe with repertoires of poems available to human consumption but not in an appropriate condition to be accessible and reusable by the Semantic Web. These systems are not interoperable; they are in fact locked in their databases and proprietary software, not suitable to be linked in the Semantic Web. A way to make this data interoperable is to develop a MAP in order to be able to publish this data available in the LOD ecosystem, and also to publish new data that will be created and modeled based on this MAP. To create a common data model for EP is not simple since the existent data models are based on conceptualizations and terminology belonging to their own poetical traditions and each tradition has developed an idiosyncratic analytical terminology in a different and independent way for years. The result of this uncoordinated evolution is a set of varied terminologies to explain analogous metrical phenomena through the different poetic systems whose correspondences have been hardly studied – see examples in González-Blanco & Rodríguez (2014a and b). This work has to be done by domain experts before the modeling actually starts. On the other hand, the development of a MAP is a complex task though it is imperative to follow a method for this development. The last years Curado Malta & Baptista (2012, 2013a, 2013b) have been studying the development of MAP's in a Design Science Research (DSR) methodological process in order to define a method for the development of MAPs (see Curado Malta (2014)). The output of this DSR process was a first version of a method for the development of Metadata Application Profiles (Me4MAP) (paper to be published). The DSR process is now in the validation phase of the Relevance Cycle to validate Me4MAP. The development of this MAP for poetry will follow the guidelines of Me4MAP and this development will be used to do the validation of Me4MAP. The final goal of the POSTDATA project is: i) to be able to publish all the data locked in the WIS, in LOD, where any agent interested will be able to build applications over the data in order to serve final users; ii) to build a Web platform where: a) researchers, students and other final users interested in EP will be able to access poems (and their analyses) of all databases; b) researchers, students and other final users will be able to upload poems, the digitalized images of manuscripts, and fill in the information concerning the analysis of the poem, collaboratively contributing to a LOD dataset of poetry.

La terminologie, telle quelle se pratique au Québec depuis une cinquantaine d'années, s'inscrit dans un projet d'aménagement linguistique qui vise à faire du français la langue d'utilisation commune sur le territoire québécois. La mise en œuvre de ce projet a été confiée à l'Office québécois de la langue française. Dans le cadre de la présente thèse, nous évaluons l'influence de l'aménagement linguistique sur l'orientation des travaux de terminologie à l'Office québécois de la langue française de 1961 à 2004. Notre objectif principal est de montrer que le projet d'aménagement linguistique a engendré une intense activité terminologique à la suite de l'adoption de diverses lois linguistiques au cours des cinquante dernières années. Plus précisément, nous analysons l'impact de ces lois sur le développement de la pratique de la terminologie. Pour ce faire, nous avons proposé six périodes qui caractérisent les travaux de terminologie de l'Office québécois de la langue française de 1961 à 2004. À l'intérieur de ces six périodes, nous analysons les mandats que les lois linguistiques ont confiés à l'Office et leurs répercussions sur l'orientation de ses travaux terminologiques. À l'instar de la problématique que nous avons esquissée au début de cette thèse, les résultats de notre recherche révèlent que la pratique de la terminologie est liée au projet de société que le Québec s'est donné pour assurer la défense du français sur son territoire. En outre, l'adoption des lois linguistiques a favorisé le développement de la pratique de la terminologie. Cette pratique a évolué en fonction des différents mandats confiés à l'Office québécois de la langue française qui a mis au point une méthodologie de travail en terminologie. C'est dans le cadre de l'aménagement linguistique que la terminologie s'est développée au Québec et qu'elle est devenue l'instrument clé de la mise en œuvre du projet d'aménagement linguistique québécois.

L’objectif de ce travail était d’apporter une réflexion sur les influences du colonialisme européen aux XVII-XVIIIe siècles. Ayant déjà rédigé mon mémoire de fin de maîtrise sur la Corinthe archaïque et ses colonies, j’ai souhaité approfondir la question, en choisissant de situer la problématique dans un contexte historiographique plus large, dans le temps comme dans l’espace. Plusieurs auteurs se sont intéressés aux réceptions de l’Antiquité à des périodes spécifiques (Grell et Alexandre le Grand en France, Richard et les influences antiques de la Révolution américaine,…). Cependant, aucune analyse sur le long terme n’avait encore été fournie, pas davantage qu’une réflexion de fonds sur la place de l’Antiquité dans la manière de penser les colonies en Europe moderne. Cet état de fait, de même que la relative rareté des sources modernes traitant des colonies grecques, m’ont obligé à élargir au maximum le champ de recherche, en y incluant des auteurs qui, s’ils ne se préoccupèrent pas de colonisation, recoururent néanmoins au précédent grec pour illustrer des problématiques de leur temps. Toutefois, il est possible de constater à quel point les répertoires historiographiques concernant la Grèce antique et ses colonisations se sont développés dans le courant de ces deux siècles qui virent l’apogée et la chute des premiers empires coloniaux européens en Amérique du nord. Si la comparaison à l’Histoire grecque ne relevait souvent que du Topos et de la propagande (comme dans le cas de la comparaison du Grand Condé ou de Louis XIV à Alexandre le Grand), son utilisation dans le cadre de controverses à plus large échelle outrepassait aussi le seul lieu commun pour s’inscrire dans un discours rhétorique plus approfondi. Le choix de la colonisation grecque comme modèle de comparaison s’imposait d’autant plus logiquement que les divers auteurs, depuis les premiers colons jusqu’aux pères fondateurs américains, insistaient sur les mérites économiques des colonies européennes. D’autres régimes, comme l’empire espagnol au XVIe siècle ou l’empire britannique au XIXe siècle, ont davantage recouru à une terminologie d’inspiration romaine. En effet, leur politique se fondait plus sur l’idée d’une extension impérialiste de l’État que sur une vision commerciale du colonialisme. L’article de Krishan Kumar demeure l’un des plus importants sur la question. La réception de l’Histoire des colonies grecques aux Temps modernes fut avant tout le fruit d’une tentative de définition du colonialisme comme phénomène global, et d’une volonté de situer les nations européennes dans un contexte remontant aux origines de l’Occident. À l’heure où l’Europe amorçait sa domination sur la totalité de la planète, et où la course à la colonisation s’accélérait, la majorité des auteurs s’abritaient derrière l’image de thalassocraties antiques qui, si elles ne dénotaient pas un pouvoir politique centralisé, n’en contribuèrent pas moins à imposer la culture fondatrice de la pensée occidentale à tout le bassin méditerranéen. Quant aux guerres qui poussèrent les puissances antiques les unes contre les autres, elles ne faisaient qu’augurer des conflits à large échelle que furent les guerres franco-britanniques du XVIIIe siècle.

La description des termes dans les ressources terminologiques traditionnelles se limite à certaines informations, comme le terme (principalement nominal), sa définition et son équivalent dans une langue étrangère. Cette description donne rarement d’autres informations qui peuvent être très utiles pour l’utilisateur, surtout s’il consulte les ressources dans le but d’approfondir ses connaissances dans un domaine de spécialité, maitriser la rédaction professionnelle ou trouver des contextes où le terme recherché est réalisé. Les informations pouvant être utiles dans ce sens comprennent la description de la structure actancielle des termes, des contextes provenant de sources authentiques et l’inclusion d’autres parties du discours comme les verbes. Les verbes et les noms déverbaux, ou les unités terminologiques prédicatives (UTP), souvent ignorés par la terminologie classique, revêtent une grande importance lorsqu’il s’agit d’exprimer une action, un processus ou un évènement. Or, la description de ces unités nécessite un modèle de description terminologique qui rend compte de leurs particularités. Un certain nombre de terminologues (Condamines 1993, Mathieu-Colas 2002, Gross et Mathieu-Colas 2001 et L’Homme 2012, 2015) ont d’ailleurs proposé des modèles de description basés sur différents cadres théoriques. Notre recherche consiste à proposer une méthodologie de description terminologique des UTP de la langue arabe, notamment l’arabe standard moderne (ASM), selon la théorie de la Sémantique des cadres (Frame Semantics) de Fillmore (1976, 1977, 1982, 1985) et son application, le projet FrameNet (Ruppenhofer et al. 2010). Le domaine de spécialité qui nous intéresse est l’informatique. Dans notre recherche, nous nous appuyons sur un corpus recueilli du web et nous nous inspirons d’une ressource terminologique existante, le DiCoInfo (L’Homme 2008), pour compiler notre propre ressource. Nos objectifs se résument comme suit. Premièrement, nous souhaitons jeter les premières bases d’une version en ASM de cette ressource. Cette version a ses propres particularités : 1) nous visons des unités bien spécifiques, à savoir les UTP verbales et déverbales; 2) la méthodologie développée pour la compilation du DiCoInfo original devra être adaptée pour prendre en compte une langue sémitique. Par la suite, nous souhaitons créer une version en cadres de cette ressource, où nous regroupons les UTP dans des cadres sémantiques, en nous inspirant du modèle de FrameNet. À cette ressource, nous ajoutons les UTP anglaises et françaises, puisque cette partie du travail a une portée multilingue. La méthodologie consiste à extraire automatiquement les unités terminologiques verbales et nominales (UTV et UTN), comme Ham~ala (حمل) (télécharger) et taHmiyl (تحميل) (téléchargement). Pour ce faire, nous avons adapté un extracteur automatique existant, TermoStat (Drouin 2004). Ensuite, à l’aide des critères de validation terminologique (L’Homme 2004), nous validons le statut terminologique d’une partie des candidats. Après la validation, nous procédons à la création de fiches terminologiques, à l’aide d’un éditeur XML, pour chaque UTV et UTN retenue. Ces fiches comprennent certains éléments comme la structure actancielle des UTP et jusqu’à vingt contextes annotés. La dernière étape consiste à créer des cadres sémantiques à partir des UTP de l’ASM. Nous associons également des UTP anglaises et françaises en fonction des cadres créés. Cette association a mené à la création d’une ressource terminologique appelée « DiCoInfo : A Framed Version ». Dans cette ressource, les UTP qui partagent les mêmes propriétés sémantiques et structures actancielles sont regroupées dans des cadres sémantiques. Par exemple, le cadre sémantique Product_development regroupe des UTP comme Taw~ara (طور) (développer), to develop et développer. À la suite de ces étapes, nous avons obtenu un total de 106 UTP ASM compilées dans la version en ASM du DiCoInfo et 57 cadres sémantiques associés à ces unités dans la version en cadres du DiCoInfo. Notre recherche montre que l’ASM peut être décrite avec la méthodologie que nous avons mise au point.

The proliferation of new mobile communication devices, such as smartphones and tablets, has led to an exponential growth in network traffic. The demand for supporting the fast-growing consumer data rates urges the wireless service providers and researchers to seek a new efficient radio access technology, which is the so-called 5G technology, beyond what current 4G LTE can provide. On the other hand, ubiquitous RFID tags, sensors, actuators, mobile phones and etc. cut across many areas of modern-day living, which offers the ability to measure, infer and understand the environmental indicators. The proliferation of these devices creates the term of the Internet of Things (IoT). For the researchers and engineers in the field of wireless communication, the exploration of new effective techniques to support 5G communication and the IoT becomes an urgent task, which not only leads to fruitful research but also enhance the quality of our everyday life. Massive MIMO, which has shown the great potential in improving the achievable rate with a very large number of antennas, has become a popular candidate. However, the requirement of deploying a large number of antennas at the base station may not be feasible in indoor scenarios. Does there exist a good alternative that can achieve similar system performance to massive MIMO for indoor environment? In this dissertation, we address this question by proposing the time-reversal technique as a counterpart of massive MIMO in indoor scenario with the massive multipath effect. It is well known that radio signals will experience many multipaths due to the reflection from various scatters, especially in indoor environments. The traditional TR waveform is able to create a focusing effect at the intended receiver with very low transmitter complexity in a severe multipath channel. TR's focusing effect is in essence a spatial-temporal resonance effect that brings all the multipaths to arrive at a particular location at a specific moment. We show that by using time-reversal signal processing, with a sufficiently large bandwidth, one can harvest the massive multipaths naturally existing in a rich-scattering environment to form a large number of virtual antennas and achieve the desired massive multipath effect with a single antenna. Further, we explore the optimal bandwidth for TR system to achieve maximal spectral efficiency. Through evaluating the spectral efficiency, the optimal bandwidth for TR system is found determined by the system parameters, e.g., the number of users and backoff factor, instead of the waveform types. Moreover, we investigate the tradeoff between complexity and performance through establishing a generalized relationship between the system performance and waveform quantization in a practical communication system. It is shown that a 4-bit quantized waveforms can be used to achieve the similar bit-error-rate compared to the TR system with perfect precision waveforms. Besides 5G technology, Internet of Things (IoT) is another terminology that recently attracts more and more attention from both academia and industry. In the second part of this dissertation, the heterogeneity issue within the IoT is explored. One of the significant heterogeneity considering the massive amount of devices in the IoT is the device heterogeneity, i.e., the heterogeneous bandwidths and associated radio-frequency (RF) components. The traditional middleware techniques result in the fragmentation of the whole network, hampering the objects interoperability and slowing down the development of a unified reference model for the IoT. We propose a novel TR-based heterogeneous system, which can address the bandwidth heterogeneity and maintain the benefit of TR at the same time. The increase of complexity in the proposed system lies in the digital processing at the access point (AP), instead of at the devices' ends, which can be easily handled with more powerful digital signal processor (DSP). Meanwhile, the complexity of the terminal devices stays low and therefore satisfies the low-complexity and scalability requirement of the IoT. Since there is no middleware in the proposed scheme and the additional physical layer complexity concentrates on the AP side, the proposed heterogeneous TR system better satisfies the low-complexity and energy-efficiency requirement for the terminal devices (TDs) compared with the middleware approach.

Introduction - Learning about ageing and the appropriate management of older patients is important for all doctors. This survey set out to evaluate what medical undergraduates in the UK are taught about ageing and geriatric medicine and how this teaching is delivered. Methods – An electronic questionnaire was developed and sent to the 28/31 UK medical schools which agreed to participate. Results – Full responses were received from 17 schools. 8/21 learning objectives were recorded as taught, and none were examined, across every school surveyed. Elder abuse and terminology and classification of health were taught in only 8/17 and 2/17 schools respectively. Pressure ulcers were taught about in 14/17 schools but taught formally in only 7 of these and examined in only 9. With regard to bio- and socio- gerontology, only 9/17 schools reported teaching in social ageing, 7/17 in cellular ageing and 9/17 in the physiology of ageing. Discussion – Even allowing for the suboptimal response rate, this study presents significant cause for concern with UK undergraduate education related to ageing. The failure to teach comprehensively on elder abuse and pressure sores, in particular, may be significantly to the detriment of older patients.

Este trabalho visa a análise coreográfica das Sevilhanas através da observação sistemática do comportamento motor, pretendendo definir a Estrutura de Composição Coreográfica desta dança, através da identificação de invariantes. Objetivou-se apresentar a coreografia de Sevilhanas de forma esquematizada, numa tabela que indique a estrutura musical, coreográfica e espacial. Para cumprir o objetivo principal, procedeu-se à identificação e descrição dos passos que constituem a coreografia; à apresentação de uma proposta de terminologia para os passos; e à identificação das constantes coreográficas que permitem reconhecer a Estrutura de Composição Coreográfica. Os dados foram obtidos a partir da observação sistemática de 15 coreografias de Sevilhanas Normais retiradas de 15 vídeos didáticos realizados com o intuito de ensinar a dançar Sevilhanas. No decorrer do estudo, foram também observadas 3 coreografias de Sevilhanas Boleras. Os resultados permitem concluir que as Sevilhanas Normais têm uma Estrutura de Composição Coreográfica dividida em duas componentes, a Estrutura Coreográfica Base e a Estrutura Coreográfica Específica, pelo que se avançou com a definição do Esquema Coreográfico das Sevilhanas Normais. Concluiu-se também que a coreografia de Sevilhanas Normais é diferente da coreografia de Sevilhanas Boleras, apesar de a Estrutura Coreográfica Base ser a mesma.

Reverse logistics in construction refers to the movement of products and materials from salvaged buildings to a new construction site. While there is a plethora of studies looking at various aspects of the reverse logistics chain, there is no systematic review of literature on this important subject as applied to the construction industry. Therefore, the objective of this study is to integrate the fragmented body of knowledge on reverse logistics in construction, with the aim of promoting the concept among industry stakeholders and the wider construction community. Through a qualitative meta-analysis, the study synthesises the findings of previous studies and presents some actions needed by industry stakeholders to promote this concept within the real-life context. First, the trend of research and terminology related with reverse logistics is introduced. Second, it unearths the main advantages and barriers of reverse logistics in construction while providing some suggestions to harness the advantages and mitigate these barriers. Finally, it provides a future research direction based on the review.
