Dans cette thèse, nous nous intéressons à l'étude des courbes discrètes et ses applications en analyse d'images. Nous avons proposé une amélioration de l'estimation de courbure reposant sur le cercle circonscrit. Celle-ci repose sur la notion de segment flou maximal d'épaisseur [nu] et sur la décomposition d'une courbe discrète en sa séquence de segments flous maximaux. Par la suite, nousavons appliqué cette idée en 3D afin d'estimer la courbure et la torsion discrète en chaque point d'une courbe 3D. Au niveau de l'application, nous avons développé une méthode rapide et fiable pour détecter les points dominants dans une courbe 2D. Un point dominant est un point dont la courbure est localement maximale. Les points dominants jouent un rôle très important dans la reconnaissance de formes. Notre méthode utilise un paramètre qui est l'épaisseur des segments flous maximaux. Reposant sur cette nouvelle méthode de détection des points dominants, nous avons développé des méthodes sans paramètres de détection des points dominants. Celles-ci se basent sur une approche multi-épaisseur. D'autre part, nous nous intéressons particulièrement au cercles et arcs discrets. Une méthode linéaire a été développé pour reconnaître des cercles et arcs discrets.

It's very complicated to find out the analytical expression for every dynamical system. In that case it is possible to get an idea of the system if we know the configuration of the corresponding system. We can find the configuration space of any system if we can identify some points on it. Also we can express many spaces as a configuration space of a linkage.

The Funk–Radon transform assigns to a function on the two-sphere its mean values along all great circles. We consider the following generalization: we replace the great circles by the small circles being the intersection of the sphere with planes containing a common point ζ inside the sphere. If ζ is the origin, this is just the classical Funk–Radon transform. We find two mappings from the sphere to itself that enable us to represent the generalized Radon transform in terms of the Funk–Radon transform. This representation is utilized to characterize the nullspace and range as well as to prove an inversion formula of the generalized Radon transform.

Full textAbstract:
Depuis les 50 dernières années, de nombreux progrès ont été faits dans la compréhension du comportement asymptotique du nombre de points rationnels de hauteur bornée sur les variétés algébriques. Des conjectures précises ont été avancées par Baryrev, Manin et Peyre quant à la formule asymptotique attendue pour une variété générale.En 1962, à l'aide d'arguments issus de la méthode du cercle de Hardy et Littlewood, B. Birch a donné une estimation précise du nombre de points à coordonnées entières bornées dans une hypersurface définie par une équation homogène. Ceci revient à démontrer la conjecture de Batyrev-Manin-Peyre pour les hypersurfaces de l'espace projectif. Plus récemment, V. Blomer et J. Brüdern ont élaboré des techniques leur permettant d'établir une formule pour le comportement asymptotique du nombre de points de hauteur bornée pour des hypersurfaces d'espaces multiprojectifs définies par des équations multihomogènes diagonales. Parallèlement, D. Schindler a démontré la conjecture pour des hypersurfaces générales d'espaces biprojectifs, à l'aide de développements de la méthode de Birch.L'objet de cette thèse a été d'utiliser et de généraliser les techniques de Schindler, Blomer et Brüdern afin de démontrer la validité de la conjecture de Batyrev-Manin-Peyre pour le cas d'hypersurfaces de variétés toriques plus générales.Ce travail est composé de trois parties. La première partie concerne le cas particulier des hypersurfaces de tridegré (1,1,1) d'un espace triprojectif. Ce cas particulier constitue une première extension des techniques de Schindler à des variétés toriques dont le rang du groupe de Picard est 3. La deuxième partie est consacrée à l'étude des hypersurfaces d'une famille de variétés toriques dont le rang du groupe de Picard est 2 et contenant la famille des espaces biprojectifs. Il s'agit en effet d'étendre la méthode de Schindler afin d'obtenir une formule asymptotique pour le nombre de points de hauteur bornée sur ces variétés. Enfin, dans la dernière partie, nous généralisons les méthodes développées dans les deux parties précédentes à des hypersurfaces des variétés toriques complètes lisses de rang de groupe dont le cône effectif est supposé simplicial, ce qui nous permet de démontrer la conjecture de Batyrev-Manin-Peyre pour ces variétés<br>For the last 50 years, many progresses have been made in the understanding of the asymptotic behaviour of the number of rational points of bouded height on algebraic varieties. Some precise conjectures have been advanced by Batyrev, Manin, and Peyre for the expected asymptotic formula for a general variety.In 1962, using some arguments of the Hardy-Littlewood circle method, B. Birch gave a precise estimate for the number of integral points whose coordinates are bounded on an hypersurface defined by an homogeneous equation. This amounts to demonstrating the Batyrev-Manin-Peyre conjecture for hypersurfaces of projective spaces. More recently, V. Blomer and J. Brüdern developed some methods permitting to establish a formula for the asymptotic growth of the number of points of bounded height on hypersurfaces of multiprojective spaces defined by multihomogeneous diagonal equations. In the same time, D. Schindler proved the conjecture for general hypersurfaces of biprojective spaces by using some developements of the method of Birch.The aim of this thesis was to use and generalize the methods of Schindler, blomer, and Brüdern in order to prove the Batyrev-Manin-Peyre conjecture in the case of hypersurfaces of some general toric varieties.This work contain three parts. The first one deals with the particular case of hypersurfaces of tridegree (1,1,1) of triprojective spaces. This particular case is a first extension of the method of Schindler to some toric varieties whose rank of the Picard group is 3. The second part deals with the study of hypersurfaces of a class of toric varieties whose rank of the Picard group is 2 and containing biprojective spaces. We establish a generalization of the method of Schindler method in order to find an asymptotic formula for the number of points of bounded height on these vrieties. Finally, in the last part, we generalize the methods developed in the last two part to treat the case of hypersurfaces of complete non-singular toric vareties whose effective cone is simplicial. This permits to prove the conjecture of batyrev-Manin-Peyre for these varieties

Full textAbstract:
The Gauss circle problem in classical number theory concerns the estimation of N(x) = { (m1;m2) in ZxZ : m1^2 + m2^2 <= x }, the number of integer lattice points inside a circle of radius sqrt(x). Gauss showed that P(x) = N(x)- pi * x satisfi es P(x) = O(sqrt(x)). Later Hardy and Landau independently proved that P(x) = Omega_(x1=4(log x)1=4). It is conjectured that inf{e in R : P(x) = O(x^e )}= 1/4. I. K atai showed that the integral from 0 to X of |P(x)|^2 dx = X^(3/2) + O(X(logX)^2). Similar results to those of the circle have been obtained for regions D in R^2 which contain the origin and whose boundary dD satis fies suff cient smoothness conditions. Denote by P_D(x) the similar error term to P(x) only for the domain D. W. G. Nowak showed that, under appropriate conditions on dD, P_D(x) = Omega_(x1=4(log x)1=4) and that the integral from 0 to X of |P_D(x)|^2 dx = O(X^(3/2)). A result similar to Nowak's mean square estimate is given in the case where only "primitive" lattice points, {(m1;m2) in Z^2 : gcd(m1;m2) = 1 }, are counted in a region D, on assumption of the Riemann Hypothesis.

The thesis deals with urban study for the central part of the town of Náchod, located in the proximity of the town’s historic core. The relief of the landscape lends distinctiveness to the whole area. This fact was taken into consideration when elaborating the urban concept which orientates the design towards the centre and the castle. The design is formed by three pillars – functions: square – culture, park – relax and housing. As regards the territory in question, Náchod has a great potential. My attempt was to understand it and create an area in the town centre which would have significant unified city-forming character, and which would enhance the core – the centre of the town.

Full textAbstract:
We consider systems of polynomial equations and inequalities to be solved in integers. By applying the circle method, when the number of variables is large and the system is geometrically well-behaved we give an asymptotic estimate for the number of solutions of bounded size. In the case of R homogeneous equations having the same degree d, a classic theorem of Birch provides such an estimate provided the number of variables is R(R+1)(d-1)2<sup>d-1</sup>+R or greater and the system is nonsingular. In many cases this conclusion has been improved, but except in the case of diagonal equations the number of variables needed has always grown quadratically in R. We give a result requiring only d2<sup>d</sup>R+R variables, obtaining linear growth in R. When d = 2 or 3 we require only that the system be nonsingular; when d<4 we require that the coefficients of the equations belong to a certain explicit Zariski open set. These conditions are satisfied for typical systems of equations, and can in principle be checked algorithmically for any particular system. We also give an asymptotic estimate for the number of solutions to R polynomial inequalities of degree d with real coefficients, in the same number of variables and satisfying the same geometric conditions as in our work on equations. Previously one needed the number of variables to grow super-exponentially in the degree d in order to show that a nontrivial solution exists.

Full textAbstract:
Die Entwicklung mechanischer Antriebskonzepte für nichtlineare Bewegungsaufgaben stellt bis heute ein komplexes und domänenübergreifendes Fachgebiet des Maschinenbaus dar. Auf dem Gebiet der ebenen Koppelgetriebe gibt es dabei seit vielen Jahren Versuche, die optimale Lösung für eine Aufgabe unter Berücksichtigung kinetischer Kenngrößen zu finden. Die vorliegende Arbeit stellt eine Methodik vor, die sowohl den klassischen Verfahren der Getriebetechnik als auch den Ansätzen der Mechanik zum Ausgleich der Massenwirkungen im Getriebe gerecht wird. Der entwickelte Ansatz des modulbasierten Analyse-Synthese-Parameter-Abgleiches (ASPA) erlaubt erstmals eine domänenübergreifende Simulation komplexer Antriebskonzepte auf Basis einer neuartigen modularen Synthesebibliothek. Diese lässt sich dank umfangreicher Dokumentation und der dargestellten Programmablaufpläne in beliebige Software implementieren. Die exemplarisch im Systemsimulator SimulationX implementierte Bibliothek ermöglicht somit unter anderem die Anwendung der klassischen Drei- und Vierlagensynthese im bewegten oder ruhenden Bezugssystem für Dreh- und Schubgelenkketten. Neben der Ausgabe gerundeter Getriebeabmessungen eröffnet der beschriebene Ansatz somit die Berücksichtigung kinetischer Kenngrößen wie den Pendelschwingungen in spielbehafteten Gelenken oder der Änderung der Trägheitskenngrößen während der Synthese. Weiterführend kann eine multikriterielle Optimierung der noch freien Syntheseparameter erfolgen.<br>Developing nonlinear transmitting planar coupler linkages represents a domain spanning area in mechanical engineering. In recent years many efforts have been made to determine the optimal planar linkage regarding kinetic characteristics. This thesis introduces a method linking classical synthesis procedures with mechanical approaches for a dynamically balanced mechanism. For the first time, the module based analysis-synthesis-parameter-adjustment (ASPA) allows for a domain spanning simulation of complex drive assemblies based on a novel modular synthesis library. Due to an extensive documentation and detailed program flow charts it is possible to implement the library in arbitrary software environments. The exemplarily implemented library in SimulationX allows to apply the classical three- and four-position synthesis within a steady or moving reference frame of revolute or prismatic joint chains. Further, the modules return rounded link dimensions. By applying this library according to ASPA it is now possible to account for kinetic boundaries such as pendulum oscillations of joints with joint clearance or the change of mass properties during the position synthesis. Thus, a multi-criteria optimization of the remaining free synthesis parameters can be applied.

that they are a set of two opposite vectors or a vertex set of a regular triangle respectively.
The density of a set D of n distinct unit vectors in the plane is the number

In Section 1, we study some properties about the rotations and reflections in the complex
plane. In Section 2, we introduce the notion of density and solve the minimum density
problem for two-point sets and three-point sets. In the last Section 3, we solve the minimal
density problem for four-point sets. Since density is invariant under rotations and reflections,
we need only to discuss three types of four-point sets to solve the problem

The thesis consists of two main results. The first main result is a proof that C^1 rigidity holds for circle maps with a break point for almost all rotation numbers. The second main result is a proof that C^1 robust rigidity holds for circle maps in the fractional linear transformation (FLT) pair family. That is, for this family, C^1 rigidity holds for all irrational rotation numbers. The approach taken here of proving a more general theorem that C^1 rigidity holds for circle maps with a break point satisfying a `derivatives close condition', allows us to obtain both of our main results as corollaries of this more general theorem.

碩士<br>國立臺灣海洋大學<br>運輸科學系<br>107<br>In general, the Electronic Chart Display and Information System（ECDIS）is used as a platform for the vessel positioning and chart work. For ocean going vessels, experienced mariners always adopted the information which were based on the modern navigation instrument to prepare the route planning such as navigation information, weather information and the port information for the destination. The route planning must to be done before sailing, and the generated waypoints were set to be followed. By combining the advanced navigation instruments and calculating the reasonable path range and navigation waypoints, the vessel maneuvering and mariner can issue more precise commands and it also can reduce the mental workload for the mariner. The main purpose of this research was trying to ensure safe navigation, make more appropriate decisions, and further reduce the loss of fuel consumption to achieve energy conservation and environmental protection at the same time. This study is divided into two stages of simulation analysis. The first stage of this study was evaluation of the navigation performance of the circle of acceptance range, and then evaluates the guiding performance of the multi-point steering mode（Single-point/multi-point steering mode performance comparison）. The first stage used the original waypoint, and the influence of the circle of acceptance was discussed. Here we would like to call it the Guiding circle of Acceptance steering mode.
The second stage, the study adopted the concept from experienced mariners when they perform steering the vessel with the wheel over point. This will be incorporated into the multi-point steering mode, and the ship’s maneuvering parameter K and T based on experiment result from the ship maneuvering simulation system（USDDC Maneuvering System, UMS-2011）. The selected ship C-1 container’s maneuverability will take into account, using the maximum rudder turning circle to generating two intersection points with the original preset route, replacing the original single waypoint with these two intersection points. This is called the multi-point steering mode. In this research work we will compare three kinds of guidance methods; which are the Line-of-Sight （LOS）, parallel correction（PC）guidance method and the improved parallel correction （IPC） guidance method. During the first stage of experiments we found some interested results such as the better simulation time performance with the Lpp（Length between perpendiculars） setting value of one, the average heading error performance was 2.5 times the Lpp setting value, and better average rudder performance which 3 times the Lpp setting value. The experiments also reveal that the multi-point steering mode can really improve the vessel cross track error and heading error, which means that the vessel can maintain a more precise navigation path than using the single waypoint method.

Full textAbstract:
碩士<br>國立臺南大學<br>教育學系科技發展與傳播碩士班<br>101<br>The purpose of this study is to develop the “Collaborative Strategy (CS)” and apply it to the instruction of mathematical concepts of “Point, Line, and Circle.” Lesson activities included a series of collaborative works through manipulating interactive whiteboard (IWB) of geometrical graphics. The strategy highlighted a collaboration that each learner used what they learned to help others within a heterogeneous group. A quasi-experimental research was conducted to examine learners’ performance. Two classes of 9th graders (63 students) from a junior high school in southern Taiwan were included. One class (31 students) was assigned to CS group (experimental group). The other class (32 students) was assigned to non-CS group (control group). The researcher conducted performance tests, questionnaire survey, and interviews and analyzed the data in a triangulation approach. The study found that: (1) CS yielded a significant effect toward the learning in mathematical concepts of “Point, Line, and Circle.” (2) Learners preferred CS because they felt more confident in learning mathematics with peer assistance. (3) Most learners were interested in IWB. (4) Learners were more skillful in complementary learning through peer interaction. The findings implied that the integration of CS and IWB was helpful in learning mathematical concepts for junior high school students. This study also makes suggestions for educational practice and future research.

Full textAbstract:
博士<br>國立臺灣師範大學<br>英語學系<br>98<br>Unlike most Wordsworthian studies, this dissertation aims to investigate Wordsworth in the perspective of physis/physics/physiology. It looks into Wordsworth’s world as an optic world (in which imagination is seen as “visionary gleam” and life is found to be full of “spots of time”) and as a mechanical world (in which circle, torsion, gravity, etc., are working entities for natural or human beings). It takes for its scope of study two main works of Wordsworth’s, namely, The Prelude and the Lyrical Ballads. And it refers to several Western thinkers, especially Descartes, for the physical investigation of the works. In addition, both The Prelude and the Lyrical Ballads are considered to be confessional works, explicitly and implicitly. To confess is to recognize “truth” and “virtue” (in the sense of power, force, or strength as well as in the sense of moral goodness). What Wordsworth recognizes, as expressed in both works, are the dark and light “spots of time,” which are the critical moments that foster the poet’s soul with fear and beauty, that stop life’s temporary motion or torsion with its centrifugal and centripetal forces, that make possible the replacement of the x axis of space and the y axis of time with the z axis of universal eternity, and that lead the poet to go through a full circle and enter the zero point of gravity, where mechanical motion becomes everlasting rest and “renovated virtue” becomes pure soul.
In order to explicate the optical and mechanical views on Wordsworth, the dissertation traces philosophical ideas from Plato to Deleuze besides reviewing some modern Wordsworthian studies on the “spots of time.” Furthermore, it explains such technical terms as torsion, virtue, circle, and 0 of gravity, in consideration of the dual aspects of quantity and quality, motion and rest, centrifugal and centripetal forces, nature and society, fact and imagination, space and time, x axis and y axis, body and soul, etc. The dissertation concludes that Wordsworth’s confessional literature is closely related to Descartes’ mechanical versus mental ideas, especially in the sense that to “virtualize” the “spots of time” is to idealistically make them both “virtual” by subordinating physical nature and actual fact to the mind’s imaginative creation, and “virtuous” by elevating the temporary deeds and names to the permanent truth and fame.

We present a new method to perform reliable matching between different images. This method exploits a projective invariant property between concentric circles and the corresponding projected ellipses to find complete region correspondences centered on interest points. The method matches interest points allowing for a full perspective transformation and exploiting all the available luminance information in the regions. Experiments have been conducted on many different data sets to compare our approach to SIFT local descriptors. The results show the new method offers increased robustness to partial visibility, object rotation in depth, and viewpoint angle change.<br>Singapore-MIT Alliance (SMA)

博士<br>國立交通大學<br>資訊科學學系<br>83<br>The Hough transform (HT) is a robust method for detecting
analytically described curves. However, the use of the HT needs
a lot of computing time and storage for evaluating all possible
parameters and accumulating them in the corresponding entries
of the parameter space. In order to reduce the requirements of
computing time and storage, many modified versions of the HT
have been proposed to decompose the parameteration into several
small stages via edge orientation information. However, these
methods suffer from noises and quantization error. To treat
these disadvantages, here, we propose several methods for
detecting lines, circles and ellipses via their global
geometric properties. These detectors significantly reduce the
time required to evaluate possible parameters without using
edge orientation information. Experimental results are also
given to show the correctness and effectiveness of the proposed
methods. In addition, it is shown that these methods can be
applied to land-register map and machine-part drawing
recognition.

Full textAbstract:
A genus-two Riemann surface admits a canonical decomposition into Dirichlet polygons determined by its six Weierstrass points. All possible associated graphs are determined explicitly from circle packing problems, solved by systems of linear inequalities whose solutions determine a finite 6-dimensional polyhedral complex in 12-dimensional space. The 6-dimensional Moduli Space of genus-two Riemann surfaces inherits a canonical explicit decomposition into Euclidean polyhedra, giving new natural coordinates for the Teichmuller Space of all possible constant curvature geometries on a marked genus-two surface.

O objeto de estudo desta dissertação assenta no confronto entre a Contabilidade e o Direito Fiscal. A colisão entre ambos, hoje novamente presente devido à criação do Sistema de Normalização Contabilística, cria tensões que afetam a fiscalidade das empresas e a Administração Fiscal nas relações jurídico-tributárias entre estas. Numa tentativa de melhor compreender o surgimento destas tensões, bem como as resoluções encontradas pelo legislador fiscal e pelos tribunais, recorremos a alguns acórdãos arbitrais referentes à colisão entre o recente artigo 18º nº 9 al. a) do CIRC e o revogado artigo 45º nº 3 do CIRC, que incidindo essencialmente sobre o mesmo objeto, o Justo Valor, contemplavam estatuições assimétricas, que prejudicam as empresas enquanto contribuintes. A análise destes confrontos é feita com recurso à legislação tributária e ao normativo contabilístico, ambos enquadrados à luz dos Princípios Gerais do Direito Fiscal, com especial foco no Princípio da Realização, fazendo também recurso à interpretação da lei fiscal e às necessidades subjacentes à criação de cada norma. Sem nunca perder de vista a linha que guia toda a estrutura desta dissertação – o confronto entre a contabilidade e o Direito Fiscal – procuramos desconstruir esta tensão com recurso a exemplos específicos, de forma que para rendimentos contabilísticos idênticos ou análogos, o mesmo processo de enquadramento com a lei fiscal possa ser utilizado.<br>The object of this dissertation is the collision between Accounting and Taxation. Trying to understand the continuous confrontation between this two realities that so many times hurt the profits to be earned by the companies, we analyzed the tension between the article 18º nº 9 point a) of the Portuguese Corporate Income Tax Code (CIRC), referring to financial assets at fair value put through the profit or loss account, and the article 45º nº 3 of the Portuguese Corporate Income Tax Code, that established that the losses derived from this financial assets would be accounted by half of its value, the collision between this two articles created an asymmetry of treatment given by the tax legislation to the same subject. The analysis made in this dissertation recurs to the General Principles of the Portuguese Tax Law, giving special attention the Realization Principle and the spirit behind the creation of the tax norms, in order to support the solutions given by the legislator to the referred confrontations, in an attempt to apply it to similar problems.
