The goal of this thesis is to use machine learning methods for datasets of scanned faces and to create a program that allows to explore and edit faces represented as triangle meshes with a number of controls. Firstly we had to reduce dimension of triangle meshes by PCA and then we tried to predict shape of meshes according to physical properties like weight, height, age and BMI. The modeled faces can be used in animation or games.

Iremos demonstrar alguns teoremas "famosos" utilizados na resolução de problemas que envolvem semelhanças, e outros que são desconhecidos para os jovens do ensino básico tais como Teorema de Ceva, Triângulo medial e a linha de Euler e Triângulos Pedal mas que têm a sua importância na matemática. / Abstract: The present work deals with the similarities of segments and geometric figures, especially the triangle. We will demonstrate some "famous" theorems used to solve problems involving similarities, and others that are unknown to the youngsters of elementary education such as Ceva Theorem, Medial Triangle and Euler aligns and Pedal Triangles but which have their importance in mathematics. / Mestre

近年來，俄羅斯、中國、印度三國經濟發展迅速，國力蒸蒸日上。俄中印三國因地緣因素，自冷戰時期彼此之對外戰略便相互影響。到了後冷戰時期，國際體系轉變成由美國所引領之「一超多強」體系，三國更找到共同合作的利基，促成三國之間的合作。在冷戰與後冷戰兩段時期，三國關係的發展，呈現不同的風貌。 從國際關係現實主義來看，國家作為理性的行為者，追求國家相對利益為決定國家行為的基本因素，而此行為為一場零和賽局。以此為脈絡，美國學者羅德明在冷戰時期發展成的戰略三角理論，成為探討三國關係之經典。台灣學者包宗和更觀察到，後冷戰時期的國家，因國際體系的改變，戰略三角理論由傳統的「個體論」走向「總體論」的取向。本文試圖以戰略三角理論為途徑，探討冷戰與後冷戰兩段時期，俄中印三國關係之演變。 首先，本文探討從二戰結束、冷戰開始以來，俄中印三國在兩極體系下的互動模式；其次探討後冷戰時期的關係演變。再整理出後冷戰三國關係的發展，對國際情勢、美國對外戰略的影響。最後由三國之間互動的實例，對戰略三角理論作出反饋。 / In recent years, the economic growth in Russia, China and India soars rapidly and their national strength does, too. Due to the geopolitical factors, these three nations affected each other in strategies during the cold war. After the cold war, the international system changed into a US-lead “uni-multi-polar system.” Russia, China and India found the common niche which promoted their cooperation. In the two periods of cold war and post-cold war, the relationship among these three countries displayed great differences. From the point of view in realism, the nations as rational actors pursue relative national interests as their goals which turn into a zero-sum game. Lowell Dittmer developed this idea into the “Strategic Triangle Theory” to discuss trilateral relationship among nations in cold war. Tzong-Ho Bau argued that the nations in post-cold war pursue common national interests as a methodological holism which is different from the methodological individualism in the cold war. Through strategic triangle approach, this thesis tries to explore the relationship among Russia, China and India. First, the thesis discusses the relationship among Russia, China and India during the cold war and then the period after the cold war. Second, the thesis discusses the influence which Russia, China and India make on international circumstances and US strategies. Finally, by a review from Russia-China-India trilateral relationship, the thesis gives a feedback to the strategic triangle theory.

An examination of the logical relationships between attitude statements suggests that attitudes can be ordered according to favourability, and can also stand in relationships of implication to one another. The traditional representation of attitudes, as points on a single dimension, is inadequate for representing both these relations but representing attitudes as intervals on a single dimension can incorporate both favourability and implication. An interval can be parameterised using its two endpoints or alternatively by its midpoint and latitude. Using this latter representation, the midpoint can be understood as the �favourability� of the attitude, while the latitude can be understood as its �generality�. It is argued that the generality of an attitude statement is akin to its latitude of acceptance, since a greater semantic range increases the likelihood of agreement. When Coombs� Theory of Unidimensional Unfolding is reformulated using the interval representation, the key question is how to measure the distance between two intervals on the dimension. There are innumerable ways to answer this question, but the present study restricts attention to eighteen possible �distance� measures. These measures are based on nine basic distances between intervals on a dimension, as well as two families of models, the Minkowski r-metric and the Generalised Hyperbolic Cosine Model (GHCM). Not all of these measures are distances in the strict sense as some of them fail to satisfy all the metric axioms. To distinguish between these eighteen �distance� measures two empirical tests, the triangle inequality test, and the aligned stimuli test, were developed and tested using two sets of attitude statements. The subject matter of the sets of statements differed but the underlying structure was the same. It is argued that this structure can be known a priori using the logical relationships between the statement�s predicates, and empirical tests confirm the underlying structure and the unidimensionality of the statements used in this study. Consequently, predictions of preference could be ascertained from each model and either confirmed or falsified by subjects� judgements. The results indicated that the triangle inequality failed in both stimulus sets. This suggests that the judgement space is not metric, contradicting a common assumption of attitude measurement. This result also falsified eleven of the eighteen �distance� measures because they predicted the satisfaction of the triangle inequality. The aligned stimuli test used stimuli that were aligned at the endpoint nearest to the ideal interval. The results indicated that subjects preferred the narrower of the two stimuli, contrary to the predictions of six of the measures. Since these six measures all passed the triangle inequality test, only one measure, the GHCM (item), satisfied both tests. However, the GHCM (item) only passes the aligned stimuli tests with additional constraints on its operational function. If it incorporates a strictly log-convex function, such as cosh, the GHCM (item) makes predictions that are satisfied in both tests. This is also evidence that the latitude of acceptance is an item rather than a subject or combined parameter.

La mesure des paramètres de violation de CP dans les désintégrations du type b->uubard permet en principe d'avoir accès à sin(2alpha), où alpha est l'un des angles du triangle d'unitarité. Cependant, la présence de diagrammes à boucle, appelées diagrammes pingouins, complique l'interprétation de la mesure expérimentale, qui ne donne en fait accès qu'à une valeur effective de \alpha : æff. Les mesures dans le canal B0->rho0rho0 permettent de réaliser pour la première fois une analyse d'isospin complète dans les modes B->rhorho, et donc en principe de déterminer le décalage \alpha-æff induit par les diagrammes pingouins. La désintégration B0->rho0rho0 a été étudiée en utilisant l'échantillon final de BABAR, soit $465 10^6$ désintégrations $\Y4S\to\BB$, collectées auprès du collisionneur \epem asymétrique PEP-II. Le rapport d'embranchement du mode B0->rho0rho0 a été mesuré BR=0.92±0.32±0.14 10^{-6} ainsi que la fraction de polarisation longitudinale fL= 0.75+0.11-0.14±0.03. La signifiance du signal B0->rho0rho0 est de 3.1 \sigma en prenant en compte les erreurs systématiques. La dépendance temporelle de la composante longitudinale a été étudiée et les paramètres de violation CP ont également été mesurés: S^{00}_L = 0.3±0.7±0.2, C^{00}_L = 0.2±0.8±0.2. L'implication de ces résultats sur l'angle $\alpha$ du triangle d'unitarité a été étudiée en effectuant une analyse d'isospin. En utilisant les mesures de BABAR pour les modes B->rho+rho- et B±->rho±rho0, la limite supérieure à 68% (90%) sur le décalage induit par la présence de diagrammes pingouins est donnée par: |\alpha-æff|<15.6° (<17.6°)

Ce document présente le travail effectué au sein de l'expérience BABAR ainsi qu'une étude phénoménologique sur l'interprétation des mesures de physique du B reliées au triangle d'unitarité. L'électronique de lecture du détecteur Cherenkov de BABAR, le DIRC, et en particulier, le convertisseur temps-numérique conçu au LPNHE sont décrits. Deux résultats majeurs de la collaboration BABAR sont également présentés : la mesure du paramètre sin2β dans les modes b → ccs qui a permis la mise en évidence de la violation de CP dans le domaine des B en 2001 et l'étude des asymétries CP dans le canal B0 → π+π−. Les contraintes sur le triangle d'unitarité, provenant de mesures dans le système K0K0, des désintégrations semi-leptoniques des B, des paramètres d'oscillation BB sont en excellent accord avec celles de sin2β et α.

<p>It is difficult for designers to explain what they do. In addition,those unfamiliar with design do not understand the rigor and logic of design thinking and process .We can’t formulate pre defined model for design process because every design situation is unique and new situation. But I tried to formulate my own model for design process as common with Inspirations from my supervisors/Lectures. I tried to describe what is design? And what is design process? In this paper.This personal position paper explores the personal improvement throughout the course work and what I learnt though out the course work.</p>

This study focuses on how the HIV and Aids pandemic affects educators in primary schools and how these educators need to be supported to cope more resiliently with the challenges posed by the HIV/Aids pandemic. This study needed to understand how primary school educators experienced the impact of the HIV/Aids pandemic, both professionally and personally. Educators in general are personally affected by the HIV/Aids pandemic emotionally, physically, spiritually and socially. Affected educators are professionally affected by the HIV/Aids, when they are burdened by a large numbers of orphans in their classes, absenteeism of learners and colleagues, poor performance of both educators and learners, high workload and multiple roles they have to perform. The impacts, both personal and professional, are mostly negative. However, to date no study has focused on the impacts of the pandemic on primary school educators. In this study, a phenomenological design was followed. Interviews were conducted with a carefully recruited sample of participants (i.e. primary school educators affected by the HIV/Aids pandemic either in their families or by having orphans in their classes) in the Vaal Triangle area. The researcher recruited participants by means of snowball sampling. Fifteen affected educators participated in this study. Primary school educators interviewed, noted poor emotional, spiritual, physical and social health. They also reported that they do not cope with their duties as educators effectively. Affected primary school educators are in need of comprehensive support to deal with the HIV/Aids pandemic related stressors from the DoE, SMT's, colleagues and the community at large. Affected educators noted that they need to be supported, by means of team work with colleagues and the community; medical support; amongst others HIV education for learners, educators and parents and practical support and counselling for dealing with difficulties created by the HIV/Aids pandemic. / Thesis (M.Ed.)--North-West University, Vaal Triangle Campus, 2009.

This study seeks to discover more specifically how the Bible, rather than traditions, comfortable habits, or past practices, should guide us in achieving qualitative and quantitative church-growth in the Vaal Triangle, and in doing so to investigate different models, with the view of suggesting one typical to the conditions in the area. The literature review revealed that the local churches as they exist today are in disrepute. Together with other societal institutions, they are suspect, distrusted and no longer accepted at face value. Moreover, different societies or associations of Christians are found claiming to themselves and denying to others, the character and privilege of a Christian church; and opinions widely differing from each other are held as to the meaning of the word Church. In our time the word church has assumed various contemporary uses: the place of worship, a particular denomination, an area or nation, the universal body of believers, a local group of believers. Recourse to Scriptures must be sought for ecclesiastical formulations. The contextual study has revealed that the Vaal Triangle is characterised by differences in ethnic origin, language, and religion. Another feature about the Vaal Triangle is that some families are religiously bi-cultural i.e., members of the same family unit belong to different religious persuasions. In other instances the members of the same family unit belong to different denominations. This difference in church affiliation is as a result of various (and often confusing) church practices in the area. Moreover, there are a number of groups in existence in the Vaal Triangle called 'the Church' but certainly are not what the Lord said he would build, nor do they measure up to what the New Testament means when it speaks of the Church. This study endeavours to think afresh biblically and theologically, about the nature, structure and dynamics of the Local Church in the Vaal Triangle. The model proposed in this study namely, the Pastoral Family Model (PFM) seeks to integrate the whole life and witness of the Local Church in a balanced and co-ordinated way. This model uses all members of the household of God who can contribute to the growth of the Local Church by penetrating the community in other ways. / Thesis (Ph.D. (Biblical Studies))--North-West University, Vaal Triangle Campus, 2009.

"Die schmale Brücke" ist eine Dreiecksgeschichte, die das Ringen zweier ungleicher Männer um eine junge Frau schildert. Der fleißige und solide Mittelschulrektor Peter Hansen, der unter der Kinderlosigkeit und Kälte seiner Frau leidet, trifft nach dem Ersten Weltkrieg seinen "Jugendfeind", den redegewandten, bei den Damen hoch beliebten Werner Hagemann wieder, welcher im Zug die Lehrerin Ursula Wüstenhagen kennengelernt hat, eine Kollegin Peter Hansens, in die dieser sich verliebt hat. In schwüler Gesprächsatmosphäre entwickelt sich eine Rivalität, die zunehmend bedrohliche Züge annimmt. Mordgedanken keimen auf. Schließlich fordert Peter Hansen, auf ein Gottesurteil hoffend, Werner Hagemann zu einem lebensgefährlichen Kräftemessen auf einer Brücke auf. Die Erzählung ist das einzige Werk von F. E. Peters, das im Lehrermilieu spielt. Verwoben mit der spannungsreichen Dreiecksbeziehung sind Themen der Frauenemanzipation und modernen Pädagogik sowie zahlreiche literarische Reminiszenzen an den "Zauberberg" oder auch an Goethe und Hölderlin, insbesondere in der zentralen Frage der "Schicksalswürdigkeit". Der ursprünglich von Peters gewählte Titel ("Der Schicksalswürdige") wurde auf Wunsch des Verlages in "Die schmale Brücke" geändert.
