Abstract
In the Lower East Side of New York City from 1909 through 1911 a fight for change was taking place. Jewish immigrant girls put their safety on the line and brought attention to the abuse taking place in factories across the country. They first spoke out and led the Ladies' Garment Worker strike bringing attention to their cause. But it was ultimately their untimely deaths in one of the most tragic workplace disasters ever in history that finally spurred the country to action in passing new fire safety and child labor laws.

Full textAbstract:
Many properties have been found hidden in Pascal's triangle. In this paper, we will present several known properties in Pascal's triangle as well as the properties that lift to different extensions of the triangle, namely Pascal's pyramid and the trinomial triangle. We will tailor our interest towards Fermat numbers and the hockey stick property. We will also show the importance of the hockey stick properties by using them to prove a property in the trinomial triangle.

Full textAbstract:
This paper will discuss the analogues between Leibniz's Harmonic Triangle and Pascal's Arithmetic Triangle by utilizing mathematical proving techniques like partial sums, committees, telescoping, mathematical induction and applying George Polya's perspective. The topics presented in this paper will show that Pascal's triangle and Leibniz's triangle both have hockey stick type patterns, patterns of sums within shapes, and have the natural numbers, triangular numbers, tetrahedral numbers, and pentatope numbers hidden within. In addition, this paper will show how Pascal's Arithmetic Triangle can be used to construct Leibniz's Harmonic Triangle and show how both triangles relate to combinatorics and arithmetic through the coefficients of the binomial expansion. Furthermore, combinatorics plays an increasingly important role in mathematics, starting when students enter high school and continuing on into their college years. Students become familiar with the traditional arguments based on classical arithmetic and algebra, however, methods of combinatorics can vary greatly. In combinatorics, perhaps the most important concept revolves around the coefficients of the binomial expansion, studying and proving their properties, and conveying a greater insight into mathematics.

Full textAbstract:
A lot has been said about the Fibonacci Convolution Triangle, but not much has been said about the Tribonacci Convolution Triangle. There are a few ways to generate the Fibonacci Convolution Triangle. Proven through generating functions, Koshy has discovered the Fibonacci Convolution Triangle in Pascal's Triangle, Pell numbers, and even Tribonacci numbers. The goal of this project is to find inspiration in the Fibonacci Convolution Triangle to prove patterns that we observe in the Tribonacci Convolution Triangle. We start this by bringing in all the information that will be useful in constructing and solving these convolution triangles and find a way to prove them in an easy way.

L'essentiel de la production laitière de Madagascar est issu d'un "triangle" situé au coeur de l'île. Depuis des décennies, les régimes successifs ont toujours intégré le développement laitier dans leur programmes de développement respectifs, même si l'approche a souvent varié d'un régime à l'autre, les uns cherchant à privilégier la paysannerie, les autres misant sur le développement de grandes structures " modernes" et étrangères aux campagnes. Aujourd'hui, l'adoption de l'innovation par les paysans bute toujours sur certains obstacles majeurs. Les exploitations agricoles essentiellement concentrées sur les hautes terres du centre s'émiettent continuellement sous la pression démographique. La place des cultures vivrières, en particulier le riz, indispensables pour nourrir la famille, reste dominante. Dès lors coexistent deux filières : l'une, organisée autour des grandes laiteries installées vers la fin des années 1990 et alimentant entre autres les nouvelles formes de distribution ; l'autre, informelle, développée par les artisans et certains collecteurs qui participent à l'approvisionnement des agglomérations. La notion de " triangle laitier" est elle même fort contestable. La production laitière provient essentiellement du Vakinankaratra oriental favorisé par la proximité des grandes agglomérations du pays et de voies de communication modernes. Même dans cette région, les inégalités spatiales d'une commune à l'autre sont fortes

Monaghan, Andrew. "Complex hyperbolic triangle groups." Thesis, University of Liverpool, 2013. http://livrepository.liverpool.ac.uk/14033/.
Full textAbstract:
In this thesis we study the discreteness criteria for complex hyperbolic triangle groups, generated by reflections in the complex hyperbolic 2-space. A complex hyperbolic triangle group is a group of isometries of the complex hyperbolic plane generated by three complex reflections. We study discreteness of some of these groups using arithmetic and geometric methods. We show that certain complex hyperbolic triangle groups of signature (p,p,2p) and (p,q,pq/(q-p)) are not discrete. The arithmetic methods we use are those studied by Conway and Jones and Parker. We also extend these results further. We finally give an area of discreteness for complex hyperbolic triangle groups of signature [m,n,0] using the compression property.

Full textAbstract:
Modular forms are important in different areas of mathematics and theoretical physics. The theory is well known for the modular group PSL(2,Z), but is also of interest for other Fuchsian groups. In this thesis we will be interested in triangle groups with a cusp. We review some theory about mapping of hyperbolic triangles in order to derive an expression for the Hauptmodul of a triangle group, and use this to write a SageMath-program that calculates the Fourier series of the Hauptmodul. We then review some of the results presented in [4] that describe generalizations of well known concepts such as the Eisenstein series, the Serre derivative and some general results about the algebra of modular forms for triangle groups with a cusp. We correct some of the mistakes made in [4] and prove some further properties of the generators of the algebra of modular forms in the case of Hecke groups. Then we use the results from [4] to write a SageMath-program that calculates the Fourier series of the generators of the algebra of modular forms for triangle groups with a cusp and that also finds the relations between the generators in the special case of Hecke groups. Using the results from this program, we present some conjectures concerning the generators of the algebra of modular forms for a Hecke group, which, if proven to be true, give us a generalization of some of the Ramanujan equations. We conclude by explicitly calculating the generalized Ramanujan equations for the first few Hecke groups.

Full textAbstract:
Many digital models used in entertainment, medical visualization, material science, architecture, Geographic Information Systems (GIS), and mechanical Computer Aided Design (CAD) are defined in terms of their boundaries. These boundaries are often approximated using triangle meshes. The complexity of models, which can be measured by triangle count, increases rapidly with the precision of scanning technologies and with the need for higher resolution. An increase in mesh complexity results in an increase of storage requirement, which in turn increases the frequency of disk access or cache misses during mesh processing, and hence decreases performance. For example, in a test application involving a mesh with 55 million triangles in a machine with 4GB of memory versus a machine with 1GB of memory, performance decreases by a factor of about 6000 because of memory thrashing. To help reduce memory thrashing, we focus on decreasing the average storage requirement per triangle measured in 32-bit integer references per triangle (rpt).
This thesis covers compact connectivity representation for triangle meshes and discusses four data structures:
1. Sorted Opposite Table (SOT), which uses 3 rpt and has been extended to support tetrahedral meshes.
2. Sorted Quad (SQuad), which uses about 2 rpt and has been extended to support streaming.
3. Laced Ring (LR), which uses about 1 rpt and offers an excellent compromise between storage compactness and performance of mesh traversal operators.
4. Zipper, an extension of LR, which uses about 6 bits per triangle (equivalently 0.19 rpt), therefore is the most compact representation.
The triangle mesh data structures proposed in this thesis support the standard set of mesh connectivity operators introduced by the previously proposed Corner Table at an amortized constant time complexity. They can be constructed in linear time and space from the Corner Table or any equivalent representation. If geometry is stored as 16-bit coordinates, using Zipper instead of the Corner Table increases the size of the mesh that can be stored in core memory by a factor of about 8.

In the 2009-2010 academic year at the Kansas City Design Center, four students undertook a design project seeking to transform an underutilized traffic median into a usable urban public space. The space, known as “Triangle Park,” is located at Avenida Cesar E. Chavez (West 23rd Street), West Pennsylvania Avenue, and Southwest Boulevard in Kansas City, Missouri. This report describes the existing site conditions and challenges to creating an inviting public space. The report explains how the students arrived at the finalized design using precedent studies, multiple design iterations, and community input from the Westside and Crossroads neighborhood stakeholders. The finalized design focuses on providing connectivity between people, the site, and the city as a whole. Opportunities for connection are offered by improved pedestrian circulation and a comfortable, well-defined outdoor space. Three major structural interventions are proposed: an illuminated overhead canopy beneath the Interstate-35 overpass provides shelter for pedestrians; a raised walking path enhances an already prominent pedestrian route; and a wooden deck provides opportunities for sitting and lingering. The ability of the design to meet the community’s stated needs and to serve as a social public space is evaluated to determine the likelihood of positive and worthwhile project outcomes.

Full textAbstract:
This thesis contains a study of the spaces of homomorphisms from hyperbolic triangle groups to finite groups of Lie type which leads to a number of deterministic, asymptotic,and probabilistic results on the (p1, p2, p3)-generation problem for finite groups of Lie type. Let G₀ = L(pn) be a finite simple group of Lie type over the finite field Fpn and let T = Tp1,p2,p3 be the hyperbolic triangle group (x,y : xp1 = yp2 = (xy)p3 = 1) where p1, p2, p3 are prime numbers satisfying the hyperbolic condition 1/p1 + 1/p2 + 1/p3 < 1. In general, the size of Hom(T,G₀) is a polynomial in q, where q = pn, whose degree gives the dimension of Hom(T,G), where G is the corresponding algebraic group, seen as a variety. Computing the precise size of Hom(T,G₀) or giving an asymptotic estimate leads to a number of applications. One can for example investigate whether or not there is an epimorphism in Hom(T,G₀). This is equivalent to determining whether or not G₀ is a (p1, p2, p3)-group. Asymptotically, one might be interested in determining the probability that a random homomorphism in Hom(T,G₀) is an epimorphism as |G₀|→∞ . Given a prime number p, one can also ask wether there are finitely, or infinitely many positive integers n such that L(pn) is a (p1, p2, p3)-group. We solve these problems for the following families of finite simple groups of Lie type of small rank: the classical groups PSL2(q), PSL3(q), PSU3(q) and the exceptional groups 2B2(q), 2G2(q), G2(q), 3D4(q). The methods involve the character theory and the subgroup structure of these groups. Following the concept of linear rigidity of a triple of elements in GLn(Fp), used in inverse Galois theory, we introduce the concept for a hyperbolic triple of primes to be rigid in a simple algebraic group G. The triple (p1, p2, p3) is rigid in G if the sum of the dimensions of the subvarieties of elements of order p1, p2, p3 in G is equal to 2 dim G. This is the minimum required for G(pn) to have a generating triple of elements of these orders. We formulate a conjecture that if (p1, p2, p3) is a rigid triple then given a prime p there are only finitely many positive integers n such that L(pn) is a (p1, p2, p3)-group. We prove this conjecture for the classical groups PSL2(q), PSL3(q), and PSU3(q) and show that it is consistent with the substantial results in the literature about Hurwitz groups (i.e. when (p1, p2, p3) = (2, 3, 7)). We also classify the rigid hyperbolic triples of primes in algebraic groups, and in doing so we obtain some new families of non-Hurwitz groups.

Thanks to modern high-resolution acquisition techniques, 3D digital representations
of real objects are easily made of millions, or even billions, of
elements. Processing and analysing such large datasets is often a non trivial
task, due to specific software and hardware requirements.
Our system allows to process large triangle meshes by exploiting nothing
more than a standard Web browser. A graphical interface allows to select
among available algorithms and to stack them into complex pipelines, while
a central engine manages the overall execution by exploiting both hardware
and software provided by a distributed network of servers.
As an additional feature, our system allows to store work
ows and to make
them publicly available. A semantic-driven search mechanism is provided
to allow the retrieval of specific work
ows.
Besides the technological contribution, an innovative mesh transfer protocol
avoids possible bottlenecks during the transmission of data across scattered
servers. Also, distributed parallel processing is enabled thanks to an innovative
divide and conquer approach. A simplification algorithm based on this
paradigm proves that the overhead due to data transmission is negligible.

Full textAbstract:
In recent years, multiresolution models have progressed substantially. At the beginning, discrete models were employed in graphics applications, due mainly to the low degree of complexity involved in implementing them, which is the reason why nowadays they are still used in applications without high graphics requirements. Nevertheless, the increase in realism in graphics applications makes it necessary to use multiresolution models which are more exact in their approximations, which do not call for high storage costs and which are faster in visualization. This has given way to continuous models, where two consecutive levels of detail only differ by a few polygons and where, additionally, the duplication of information is avoided to a considerable extent, thus improving on the spatial cost offered by most discrete models.Advances have been made in the use of new graphics primitives which minimize the data transfer between the CPU and the GPU, apart from trying to make use of the connectivity information given by a polygonal mesh. For this purpose, graphics primitives with implicit connectivity, such as triangle strips and triangle fans, have been developed. Many continuous models based on this type of primitives have been recently developed. In these last few years, graphics hardware performance has evolved outstandingly, giving rise to new techniques which allow the continuous models to accelerate even more.
In this work, we have improved the interactive render of polygonal meshes. To tackle the problem, we firstly studied fundamental techniques to efficiently render polygonal meshes and we later made use of geometry simplification and level of detail techniques. Thus, we defined a multiresolution model that represents a polygonal mesh at any given resolution. This approach is able to manage continuous level-of-detail by smoothly adapting mesh resolution to the application requirements. Moreover, the model was modified to take the maximum advantage of the recent GPU features. We also created a modified version of the model for being used in deforming meshes. Finally, we developed an independent library to integrate our model in real-time applications.

To create a digital model of the surface of some object from a setof points, representing positions on the surface of this object, requiresinformation about the relationship between the points. This informa-tion is not immediatly accessible. Thus, for creating such a model itis necessary to establish relationsships between the points of the set.In addition, it should be possible to render the resulting modelas efficiently as possible. Modern graphics cards offer to send vertexinformations as triangle strips; by using triangle strips the informationabout the triangles can be compressed.This work is about a method for retrieving information about therelations between points in an unstructered spatial point set and trans-forming this information into triangle strips. It is based on the convexlayers of a planar point set and an algorithm for triangulating theannuli of the convex layers, which uses the Rotating Calipers.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORO principal objetivo deste trabalho é o estudo de representações que preservam tipo rho:Gamma - PU(2,1) de grupos triangulares Gamma no grupo de isometrias holomorfas do espaço hiperbólico complexo de dimensão dois H2C. O grupo triangular Gamma(p,q,r) é o grupo gerado por reflexões nos lados de um triângulo geodésico, com ângulos pi/p, pi/q e pi/r, no plano hiperbólico. Neste trabalho, nossas atenções são voltadas para os grupos Gamma (4,4,infinito) e Gamma(4,infinito,infinito). Demonstramos, entre outros resultados: Para cada caso, existe um caminho contínuo de representações rho_t que contém todas as representações que preservam tipo de Gamma em PU(2,1). Portanto, isto nos dá, em cada caso, uma descrição completa do espaço de representações de Gamma em PU(2,1). Para cada caso, existe um intervalo fechado J tal que rho_t é uma representação discreta e fiel se, e somente se, t pertence a J. Em cada caso, existe, na fronteira do espaço de deformações, uma representação com elementos parabólicos acidentais. Para demonstrar estes resultados, construímos parametrizações especiais de triângulos em H2C. Construímos poliedros fundamentais para os grupos e utilizamos uma variante do Teorema do Poliedro de Poincaré.
The main aim of this work is to study type-preserving representations p: gamma PU(2, 1) of triangle groups _ in the group of holomorphic isometries of the twodimensional complex hyperbolic space H2C. The triangle group gamma(p, q, r) is the group generated by reflections in the sides of a geodesic triangle having angles pi/p, pi/q and pi/r. We focus our attention on the groups gamma(4,4, infinit) and gamma (4,infinit, infinit). Among other results, we prove that for each case: 1. There is a continuous path of representations pt which contains all type-preserving representations of gamma in PU (2,1) up to conjugation by isometries. This gives us a complete description of the representation space of gamma in PU(2,1). 2. There is a closed interval J such that pt is a discrete and faithful representation if and only if t belongs J. 3. On the boundary of the representation space there is a representation with accidental parabolic elements. To prove these results we give special parametrizations of triangles in H2C. We also build fundamental polyhedra for the groups and use a kind of Poincares Polyhedron Theorem.

A triangle group is denoted by (p, q, r) and has finite presentation (p, q, r) = hx, y|xp = yq = (xy)r = 1i. In the 1960’s Higman conjectured that almost every triangle group has among its homomorphic images all but finitely many of the alternating groups. This was proved by Everitt in [6]. In this thesis, we combine permutation representations using the methods used in the proof of Higman’s conjecture. We do some experiments by using GAP code and then we examine the situations where the composition of a number of coset diagrams for a triangle group is imprimitive. Chapter 1 provides the introduction of the thesis. Chapter 2 contains some basic results from group theory and definitions. In Chapter 3 we describe our construction that builds compositions of coset diagrams. In Chapter 4 we describe three situations that make the composition of coset diagrams imprimitive and prove some results about the structure of the permutation groups we construct. We conduct experiments based on the theorems we proved and analyse the experiments. In Chapter 5 we prove that if a triangle group G has an alternating group as a finite quotient of degree deg > 6 containing at least one handle, then G has a quotient Cdeg−1 p o Adeg. We also prove that if, for an integer m 6= deg − 1 such that m > 4 and the alternating group Am can be generated by two product of disjoint p-cycles, and a triangle group G has a quotient Adeg containing two disjoint handles, then G also has a quotient Am o Adeg.

Dans le premier chapitre de thèse, nous estimons un système dynamique d’équations simultanées à l’aide de données de panel de pays en développement pour identifier les relations structurelles dynamiques entre la pauvreté, le PIB par habitant et la santé. Pour ce faire, nous utilisons des méthodes économétriques innovantes des données de panel incomplet pour corriger les problèmes d'endogénéité et de sélectivité liés aux données manquantes sur la pauvreté. Dans le deuxième chapitre, nous estimons plutôt les relations de cointégration entre ces trois facteurs, en utilisant des données de panel de pays en développement. Nous effectuons une analyse de cointégration des données de panel afin d'estimer les relations et les tests de causalité de long terme, ainsi qu'un modèle VECM et les fonctions de réponse impulsionnelle (IRFs). Dans le troisième chapitre de thèse, nous étudions les déterminants socio-économiques et religieux / ethniques locaux du conflit syrien actuel. Pour cela, nous fusionnons les données mensuelles de la base de données du panel de martyrs Syriens, à partir de Mars 2011 jusqu'en Avril 2016 au niveau commune, avec des facteurs socio-économiques du Recensement de 2004 et avec les données de lumière géo-localisées depuis l'espace. Nous construisons également des indicateurs ethniques/religieux détaillés par commune. Nous utilisons l'intensité lumineuse nocturne comme proxy pour la population pendant le conflit et examinons la dynamique du conflit en incluant les niveaux passés de la variable dépendanteIn the first chapter, a dynamic system of simultaneous equations is estimated using country-level panel data from developing countries to identify the dynamic causal structural relationships between Poverty, GDP per capita and Health. For this, innovative econometric methods for incomplete panel data are used to correct for endogeneity and the selectivity issues coming from missing data on poverty. In the second chapter, we estimate rather the cointegration relationships between the three factors, using country-level panel data from developing countries. We conduct a panel data cointegration in order to estimate long run relationships and causality tests. We estimate also a VECM model and we compute Impulse response functions. In the third chapter, we investigate socioeconomic and religious/ethnic local determinants of the current Syrian conflict. For this, we match monthly data from the Syrian Martyr panel database from March 2011 to April 2016 at community level with socioeconomic factors from the 2004 Census and with geolocalised luminosity from space. We also construct detailed ethnic/religious indicators. We use nighttime light intensity as a proxy for the population during the conflict and investigate the dynamics of the conflict with including past levels of the dependent variable

As an abstract group, the (2,3,n) triangle group has the presentation mit _n = < x,y : x^2 = y^3 = (yx)^n = 1 > This thesis is concerned with subgroups of finite index in mit 9, mit _11 and mit 13. With a subgroup of finite index, u, in the (2,3,11) triangle group, we associate a quintuple of non-negative integers (u,p,e,f,g), with u 1 and 5u = 132(p - 1) + 33e + 44f + 60g. We show in Theorem 1.4.6 that each quintuple, satisfying the conditions, corresponds to a subgroup of mit 11. With a subgroup of finite index, u, in the (2,3,12) triangle group, we associate a quintuple of non-negative integers (u,p,e,f,g), with u 1 and 7u = 156(p - 1) + 39e + 52f + 72g. We show in Theorem 3.3.6 that each quintuple, satisfying the conditions, corresponds to a subgroup of mit 13. With a subgroup of finite index, u, in the (2,3,9) triangle group, we associate a sextuple of non-negative integers (u,p,e,f,g1,g3) with u 1, u = f (mod 3) and u = 36(p - 1) + 9e + 12f + 16g_1 + 12g_3. We show in Theorem 2,3,9 that each sextuple, satisfying the conditions, corresponds to a subgroup of mit 9 with the following exceptions: (a) (12n+ 9,0,1,0,0,n+ 3), V n 0 (b) (24,0,0,0,0,5) (c) (24,0,0,0,3,1) (d) (24,0,0,3,0,2) Coset diagrams are used extensively in the proofs, although to prove exception (a) for mit 9, we make use of Hauptmodul equations (see [1] and [23]). Computer programs were developed to generate all quintuples satisfying the relevant conditions for (2,3,110 subgroups for u 101, all quintuples satisfying the relevant conditions for (2,3,13) subgroups for u 110, and all sextuples satisfying the relevant conditions for (2,3,9) subgroups for u 38.

The intent of this research is to identify through various statistical analyses any features, attributes, or characteristics of Madison points from Albee Phase context that could be used to distinguish them from Madison points made and used by other contemporaneous prehistoric groups. Descriptive statistics for an assemblage of Albee points will be generated to establish baseline data that theoretically characterizes a modal behavior for Albee Phase flint knappers. The Albee Phase data will be combined with comparable data for Yankeetown points and Angel Phase points. This combined data set will constitute the research universe, which will be subjected to discriminant function analysis. Discriminant function analysis is envisioned as a tool to: 1) Identify variables or a combination of variables that are unique to Albee Phase triangular points, 2) Produce a linear function to define an Albee Phase Madison point, and 3) Test that function by successfully allocating the points in the research universe to their appropriate, archaeologically defined cultural group.Department of Anthropology

Ce mémoire a pour objectif d’étudier si les trois protagonistes dans la pièce de théâtre Huisclos, écrite par Jean-Paul Sartre en 1944, sont sous l’emprise d’un jeu relationnel, notammentle Triangle Dramatique de Karpman. Un Triangle Dramatique se compose de trois rôles, uneVictime, un Persécuteur et un Sauveur. L’essence du Triangle Dramatique est de déstabiliserl’autre et de répéter des scénarios de vie souvent dysfonctionnels mis en place tôt dans la vie.The objective of this research is to study whether the three protagonists in the theatre play NoExit (Huis clos), written by Jean Paul Sartre in 1944, are influenced by a relationship game, in this case Karpman’s Drama Triangle. The Drama Triangle consists of three roles, a Victim, aPersecutor, and a Rescuer. The essence of the Drama Triangle is to destabilise others, accordingto a life script that is often dysfunctional and set early in life.

Full textAbstract:
Every triangle has a unique point, called the conformal center, from which a random (Brownian motion) path is equally likely to first exit the triangle through each of its three sides. We use concepts from complex analysis, including harmonic measure and the Schwarz-Christoffel map, to locate this point. We could not obtain an elementary closed form expression for the conformal center, but we show some series expressions for its coordinates. These expressions yield some new hypergeometric series identities. Using Maple in conjunction with a homemade Java program, we numerically evaluated these series expressions and compared the conformal center to the known geometric triangle centers. Although the conformal center does not exactly coincide with any of these other centers, it appears to always lie very close to the Second Morley point. We empirically quantify the distance between these points in two different ways. In addition to triangles, certain other special polygons and circles also have conformal centers. We discuss how to determine whether such a center exists, and where it will be found.

Cette thèse analyse le système‐monde maçonnique entre 1717 et 1921, perçu comme un produit et un agent de la modernité occidentale, comme le prototype fondateur de l’opinion publique internationale et comme une plaque tectonique de la géoculture du système-monde moderne. Elle fluctue entre une perspective globale, une perspective atlantique et un ancrage latino‐américain, fourni notamment par les principales puissances océaniques d’Amérique latine (Argentine, Brésil, Mexique). Quelle fut l’évolution globale des réseaux maçonniques au cours des XIXe et XXe siècles ? Quelle fut leur géopolitique et leur géoculture ? Dans quelle mesure peut‐on ou non parler de « système maçonnique international » ? Quelle fut la place de l’Amérique latine dans cette dynamique ? Comment le sous‐continent américain s’intégra‐t‐il dans le système‐monde maçonnique ? Les réseaux maçonniques y furent‐ils une plaque tectonique géoculturelle et des vecteurs de transferts culturels ? Contribuèrent‐ils à l’intégration du sous‐continent américain au sein de la grande communauté atlantique mais aussi à l’intégration et à l’autonomisation latino américaine ?This thesis investigates the birth and development of the Masonic world‐system, seen as a product and an agent of western modernity, as the prototype of international public opinion and as a tectonic plate of the géoculture of the modern world‐system. This text focuses on the first period of its development (1717‐1921). It fluctuates between a global perspective,an Atlantic perspective, and a Latin American anchorage, provided by the major oceanic powers of Latin America (Argentina, Brazil, and Mexico). What was the global evolution of the Masonic networks in the 19th and 20th centuries? What were their geopolitics and their géoculture? Is it possible to talk about an "international Masonic system"? What was the place of Latin America in this dynamic? How the American subcontinent became a part of the Masonic world‐system? In Latin America in the 19th and 20th centuries, were the Masonic networks a tectonic plate of géoculture and the vectors of cultural transfers? Did they contribute to the integration of the American sub‐continent in the Atlantic community? Did they contribute discreetly to the regional integration and to the Latin American empowerment ?

Full textAbstract:
This thesis develops the Triangle Model, to offer a general framework through which the work of Jürgen Habermas could be better understood and assessed. Accordingly, it is argued that, it is possible to derive a triangle in Habermas&rsquo
s thought, formed by the concerns of publicness, communication, and democracy. Each corner of the triangle corresponds to a major concern and focus of Habermas&rsquo
s project chronologically. The Triangle Model provides an overview of continuities and discontinuities in Habermas&rsquo
s work. The main discontinuity found is between the first and the second corners of the triangle, namely between publicness and communication. It is argued that this rapture stems from an interpretive turn, composed of three points: the influence of Hegelian philosophy of human interaction, the concomitant criticism of Kantian foundationalism, and the incorporation of Arendt&rsquo
s communicative concept of power. This study also emphasises that there are points indicating continuity, or unity in Habermas&rsquo
s thought. First, an intersubjective theory of truth is employed in all three concerns or corners of the triangle. Second, in all these concerns, Habermas searches for an answer to the same question: &ldquo
how to produce legitimate norms&rdquo
. The principle of publicity and the authority of the better argument voiced in the first corner of the triangle -publicness-, the discourse ethics of the second corner, and the deliberative politics of the third corner are formulated and adapted by Habermas in order to find the ways of producing legitimate norms. In this context, it is argued that the deliberative politics is based on publicness and communication
or publicness and communication are indispensable for deliberative politics.

Full textAbstract:
This thesis explores the artist-led initiatives associated with the Triangle Network in the United States, United Kingdom, Southern Africa and South Asia, between 1982 and 2015. It considers how artists have set up artist-led initiatives as a response to different circumstances in these regions, and how the idea of a network has influence this development. It is specifically concerned with how artist-led initiatives have contributed to shifts in art-world infrastructures and the writing of contemporary art histories. In particular it shows how the idea for international artist-led workshops spread from an intitial workshop in Upstate New York to an international network of partner-workshops across the world. It demonstrates how these workshops often led to: the creation of new spaces for artists to work and host visiting artists for residency programs; new exhibitions and publications; and a cosmopolitan sense of international artistic exchange. It also shows how these artistic exchanges have been concerned with better regional and South- South connectivity. It examines why and how such artist-led initiatives have been initiated and run, and what impact belonging to a network has had on the artists and artworks. The purpose of this thesis is to argue that an understanding of these types of organisations is a useful contribution to international contemporary art history, as they often represent moments of transformation and emergence. Using the notions of assemblages and networks as analytical tools, the thesis explores the possibilities these approaches have to art historical writing. Such an approach allows for analysis of heterogeneous actancts including artworks, materials, artists, institutions, books, spaces, websites, and funding streams. The intention of this thesis is to contribute an approach to writing about contemporary art history from the perspective of ‘grass-roots globalization’ (Appardurai, 1999) that can counter readings of global contemporary art based only on hegemonic institutions.

Full textAbstract:
Cluster analysis characterizes data that are similar enough and useful into meaningful groups (clusters).For example, cluster analysis can be applicable to find group of genes and proteins that are similar, to retrieve information from World Wide Web, and to identify locations that are prone to earthquakes. So the study of clustering has become very important in several fields, which includes psychology and other social sciences, biology, statistics, pattern recognition, information retrieval, machine learning and data mining [1] [2]. Cluster analysis is the one of the widely used technique in the area of data mining. According to complexity and amount of data in a system, we can use variety of cluster analysis algorithms. K-means clustering is one of the most popular and widely used among the ten algorithms in data mining [3]. Like other clustering algorithms, it is not the silver bullet. K-means clustering requires pre analysis and knowledge before the number of clusters and their centroids are determined. Recent studies show a new approach for K-means clustering which does not require any pre knowledge for determining the number of clusters [4]. In this thesis, we propose a new clustering procedure to solve the central problem of identifying the number of clusters (k) by imitating the desired number of clusters with proper properties. The proposed algorithm is validated by investigating different characteristics of the analyzed data with modified theory, analyze parameters efficiency and their relationships. The parameters in this theory include the selection of embryo-size (m), significance level (α), distributions (d), and training set (n), in the identification of clusters (k).

The Development of Regional Impact (DRI) concept was codified in Florida in the Seventies, as a measure aimed at planning for the tremendous growth and development that the State had ben experiencing. The DRI statutes that were enacted stated that any development of a magnitude in excess of certain size thresholds had to go through the DRI process to be approved.The process involves extensive studies of what the DRI's impacts will be upon the both the natural and man-made environments. Many public agencies are involved in reviewing the developer's assessments of his impacts. When these analyses are completed to the agencies' satisfaction, a Development Order is drafted. It details both the magnitude of development that will be allowed within the DRI, and the mitigation that developer will have to perform to allay his impacts upon the environments.This report examines the DRI process through the analysis of a case study. The DRI chosen for the case study was the Tampa Triangle DRI, a large tract of land located in Hillsborough County near Tampa, Florida.Department of Urban Planning

According to the popularity and variety of Internet, the requirement of 3D model become more and more important. And triangle mesh compression takes an important role base on the consideration of speed and cost. To compress triangle mesh on the premise that doesn’t change the triangle connectivity. Instead of the original expression, we express the connectivity by several operators. Also, use these operators to encode triangle mesh with active boundary selection and direction control, to decrease the probability of J operator. To Decrease the size of connectivity data, but also maintain one-pass decode process.

Let a distance-regular graph with diameter 3. Suppose the intersection number a_1 = 0，a_2 is not equal to 0, We prove the following (i)-(ii) are equivalent. (i)This graph is Q-polynomial and contains no parallelograms of length 3; (ii)This graph has classical parameters. By applying the above result we show that if a distance-regular graph has classical parameters and the intersection numbers a_1 = 0，a_2 is not equal to 0,then for each pair of vertices (v,w) at distance 2, there exists a strongly regular subgraph of the graph containing (v,w). Furthermore, for each vertex x in the strongly regular subgraph, the subgraph induced on all the vertices y which (x,y) at distance 2 in the strongly regular subgraphis is an a_2-regular connected graph with diameterat most 3.

Extending an explicit result from Bridson–Conder–Reid, this work provides an algorithm for distinguishing finite quotients between cocompact triangle groups Δ ?and lattices Γ of constant curvature symmetric 2-spaces. Much of our attention will be on when these lattices are Fuchsian groups. We prove that it will suffice to take a finite quotient that is Abelian, dihedral, a subgroup of PSL(n,Fq) (for an odd prime power q), or an Abelian extension of one of these 3 groups. For the latter case, we will require and develop an approach for creating group extensions upon a shared finite quotient of Δ? and Γ which between them have differing degrees of smoothness. Furthermore, on the order of a finite quotient that distinguishes between ?Δ and Γ, we are able to establish an effective upperbound that is superexponential depending on the cone orders appearing in each group.

Taiwan's flower market is stepping on to a stage of transformation. The traditional flower channels in Taiwan are the auction market, large and medium-sized wholesalers, and tens of thousands of flower shops and market retail systems. Basically, compared with advanced countries, like America and Japan, there are limited types of channels in Taiwan, and the main business of flower shops mainly focuses on special floral design for events such as weddings, and the institutional market of business and government offices. The average price of flowers in retail is generally considered too high to be accepted on a basis of daily purchase. It is obvious that the consumption channels and patterns of Taiwan’s flowers industry must be improved. Only by the means of changing the traditional flower marketing and retail channel to stimulate the potential demand of the market, a win-win situation between producers and consumers can be achieved, and this is what Triangle Flowers is committed to. Triangle Flowers will position itself as a daily flower provider to meet the floral needs of people in their everyday lives, and being committed to offering flower delivery services at a considerably cheaper rate than individual purchases. Our mission is to create happiness everywhere flower blooms, and bring flowers to everyone’s life.

With the growing prominence of global city regions as drivers of today’s economy, there is a need to reposition large urban areas to be competitive in this context. The success of the European trans-national urban model has raised considerable interest in the United States to delineate a similar network of multi-city mega regional systems. It has been predicted that most of the growth in this country in the next 50 years will be concentrated in about 10 such emerging mega-regions. The Texas Triangle is one such mega-region. As much as 70% of the state’s population in 2050 is expected to be concentrated within this triangular mega region, defined by the MSAs of Dallas-Fortworth, Austin-San Marcos, San Antonio and Houston. This study attempts to identify the exact spatial extent of this region based on several parameters, but primarily focusing on a network of natural environmental systems within the proposed Triangle region.text
