Abstract:

The research work presented in this thesis concern to the stability analysis of linear time-delay systems with low-order controllers. This thesis is divided into three parts.The first part of the thesis focus on the study of linear SISO (single-input/single-output) systems with input/output delays, where the feedback loop is closed with a controller of PID-type. Inspired by the geometrical approach developed by Gu et al. we propose an analytical method to find the stability regions of all stabilizing controllers of PID-type for the time-delay system. Based on this same approach, we propose an algorithm to calculate the degree of fragility of a given controller of PID- type (PI, PD and PID).The second part of the thesis focuses on the stability analysis of linear systems under an NCS (Networked System Control) based approach. More precisely, we first focus in the stabilization problem by taking into account the induced network delays and the effects induced by the sampling period. To carry out such an analysis we have adopted an eigenvalue perturbation-based approach.Finally, in the third part of the thesis we tackle certain problems concerning to the behavior of the zeros of a certain class of sampled-data SISO systems. More precisely, given a continuous-time system, we obtain the sampling intervals guaranteeing the invariance of the number of unstable zeros in each interval. To perform such an analysis, we adopt an eigenvalue perturbation-based approach.

Abstract:

Une note présente dans une partition, comme d'autres objets musicaux d'ailleurs, peut être considérée comme étant une entité possédant des propriétés qui peuvent être représentées par des valeurs élémentaires et stockées dans les différentes colonnes d'une même ligne d'une table de base de données relationnelle. La représentation de toutes les notes dans la partition sous forme de tables qui constituent un ensemble de colonnes et de lignes facilite grandement l'accès au caractère ouvert de l'analyse musicale : en effet chacun peut, en fonction de sa propre problématique, interroger la base de données qui représente et stocke la partition. La partition des Variations pour ochestre op. 30 d'Anton Webern, grâce à l'aide précieuse de base de données relationnelle, est représentée, stockée, et analysée de façon classificatoire et paradigmatique : toutes les séries, tous les intervalles, et tous les accords présents dans la partition sont identifiées pour vérifier l'existence des intervalles et des accords dominats ; les particularités liées à l'entropie, à la distribution des notes dans le registre, à la durée, à l'intensité, et à l'écriture orchestrale sont aussi identifiées<br>A note in a score, as other musical objects, can be considered as an entity having some properties. These last are represented by atomic values in columns on a line of relational data base table. The representation of all notes in the score in relational form of tables as a totality of columns and lines facilitates the access to the music analysis of open character: each can interrogate following each problematic the database that represents and stocks the score. The score of Variations for orchestra op. 30 of Anton Webern, as an example of application of the concept of “Relational Database-aided Music Analysis”, is represented, stored, and analyzed in a classificatory and a paradigmatic way: All sets, all intervals, and all chords existing in the score are retrieved, as a result on can verify the dominant intervals and chords; the particularities concerned distribution of notes in the register, duration, intensity and orchestration are also recognized

Abstract:

Dans ce travail, nous avons introduit le concept sous-jacent de PUFEM et la formulation de base lié à l'équation de Helmholtz dans un domaine borné. Le processus d'enrichissement de l'onde plane de variables PUFEM a été montré et expliqué en détail. L'idée principale est d'inclure une connaissance a priori sur le comportement local de la solution dans l'espace des éléments finis en utilisant un ensemble de fonctions d'onde qui sont des solutions aux équations aux dérivées partielles. Dans cette étude, l'utilisation des ondes planes se propageant dans différentes directions a été favorisée car elle conduit à des algorithmes de calcul efficaces. En outre, nous avons montré que le nombre de directions d'ondes planes dépend de la taille de l'élément PUFEM et la fréquence des ondes à la fois en 2D et 3D. Les approches de sélection de ces ondes planes sont également illustrés. Pour les problèmes 3D, nous avons étudié deux systèmes de distribution des directions d'ondes planes qui sont la méthode du cube discrétisé et la méthode de la force de Coulomb. Il a été montré que celle-ci permet d'obtenir des directions d'onde espacées de façon uniforme et permet d'obtenir un nombre arbitraire d'ondes planes attachées à chaque noeud de l'élément de PUFEM, ce qui rend le procédé plus souple.Dans le chapitre 3, nous avons étudié la simulation numérique des ondes se propageant dans deux dimensions en utilisant PUFEM. La principale priorité de ce chapitre est de venir avec un schéma d'intégration exacte (EIS), résultant en un algorithme d'intégration rapide pour le calcul de matrices de coefficients de système avec une grande précision. L'élément 2D PUFEM a ensuite été utilisé pour résoudre un problème de transmission acoustique impliquant des matériaux poreux. Les résultats ont été vérifiés et validés par la comparaison avec des solutions analytiques. Les comparaisons entre le régime exact d'intégration (EIS) et en quadrature de Gauss ont montré le gain substantiel offert par l'EIE en termes de temps CPU.Une 3D exacte Schéma d'intégration a été présenté dans le chapitre 4, afin d'accélérer et de calculer avec précision (jusqu'à la précision de la machine) des intégrales très oscillatoires découlant des coefficients de la matrice de PUFEM associés à l'équation 3D Helmholtz. Grâce à des tests de convergence, un critère de sélection du nombre d'ondes planes a été proposé. Il a été montré que ce nombre ne pousse que quadratiquement avec la fréquence qui donne lieu à une réduction drastique du nombre total de degrés de libertés par rapport au FEM classique. Le procédé a été vérifié pour deux exemples numériques. Dans les deux cas, le procédé est représenté à converger vers la solution exacte. Pour le problème de la cavité avec une source de monopôle située à l'intérieur, nous avons testé deux modèles numériques pour évaluer leur performance relative. Dans ce scénario, où la solution exacte est singulière, le nombre de directions d'onde doit être choisie suffisamment élevée pour faire en sorte que les résultats ont convergé.Dans le dernier chapitre, nous avons étudié les performances numériques du PUFEM pour résoudre des champs sonores intérieurs 3D et des problèmes de transmission d'ondes dans lequel des matériaux absorbants sont présents. Dans le cas particulier d'un matériau réagissant localement modélisé par une impédance de surface. Un des critères d'estimation d'erreur numérique est proposé en considérant simplement une impédance purement imaginaire qui est connu pour produire des solutions à valeur réelle. Sur la base de cette estimation d'erreur, il a été démontré que le PUFEM peut parvenir à des solutions précises tout en conservant un coût de calcul très faible, et seulement environ 2 degrés de liberté par longueur d'onde ont été jugées suffisantes. Nous avons également étendu la PUFEM pour résoudre les problèmes de transmission des ondes entre l'air et un matériau poreux modélisé comme un fluide homogène équivalent<br>In this work, we have introduced the underlying concept of PUFEM and the basic formulation related to the Helmholtz equation in a bounded domain. The plane wave enrichment process of PUFEM variables was shown and explained in detail. The main idea is to include a priori knowledge about the local behavior of the solution into the finite element space by using a set of wave functions that are solutions to the partial differential equations. In this study, the use of plane waves propagating in various directions was favored as it leads to efficient computing algorithms. In addition, we showed that the number of plane wave directions depends on the size of the PUFEM element and the wave frequency both in 2D and 3D. The selection approaches for these plane waves were also illustrated. For 3D problems, we have investigated two distribution schemes of plane wave directions which are the discretized cube method and the Coulomb force method. It has been shown that the latter allows to get uniformly spaced wave directions and enables us to acquire an arbitrary number of plane waves attached to each node of the PUFEM element, making the method more flexible.In Chapter 3, we investigated the numerical simulation of propagating waves in two dimensions using PUFEM. The main priority of this chapter is to come up with an Exact Integration Scheme (EIS), resulting in a fast integration algorithm for computing system coefficient matrices with high accuracy. The 2D PUFEM element was then employed to solve an acoustic transmission problem involving porous materials. Results have been verified and validated through the comparison with analytical solutions. Comparisons between the Exact Integration Scheme (EIS) and Gaussian quadrature showed the substantial gain offered by the EIS in terms of CPU time.A 3D Exact Integration Scheme was presented in Chapter 4, in order to accelerate and compute accurately (up to machine precision) of highly oscillatory integrals arising from the PUFEM matrix coefficients associated with the 3D Helmholtz equation. Through convergence tests, a criteria for selecting the number of plane waves was proposed. It was shown that this number only grows quadratically with the frequency thus giving rise to a drastic reduction in the total number of degrees of freedoms in comparison to classical FEM. The method has been verified for two numerical examples. In both cases, the method is shown to converge to the exact solution. For the cavity problem with a monopole source located inside, we tested two numerical models to assess their relative performance. In this scenario where the exact solution is singular, the number of wave directions has to be chosen sufficiently high to ensure that results have converged. In the last Chapter, we have investigated the numerical performances of the PUFEM for solving 3D interior sound fields and wave transmission problems in which absorbing materials are present. For the specific case of a locally reacting material modeled by a surface impedance. A numerical error estimation criteria is proposed by simply considering a purely imaginary impedance which is known to produce real-valued solutions. Based on this error estimate, it has been shown that the PUFEM can achieve accurate solutions while maintaining a very low computational cost, and only around 2 degrees of freedom per wavelength were found to be sufficient. We also extended the PUFEM for solving wave transmission problems between the air and a porous material modeled as an equivalent homogeneous fluid. A simple 1D problem was tested (standing wave tube) and the PUFEM solutions were found to be around 1% error which is sufficient for engineering purposes

Abstract:

Mon mémoire de maîtrise porte sur la gestion du timbre comme genèse à la composition de trois œuvres originales : 1) Halocline – 11’45’’ – pour flûte, clarinette, percussions, violon, alto et violoncelle; 2) Le mot juste – 9’30’’ – pour orchestre symphonique; 3) Profondeurs de champ – 16’30’’ – pour orchestre de chambre. Après la présentation de mes préoccupations artistiques, des origines et objectifs de mon travail de création, j’expose l’ensemble de mes recherches préliminaires. Finalement, les œuvres sont sommairement analysées de manière à mettre en lumière des modes de gestion du timbre ayant menés à la composition des œuvres. Ceux-ci tirent leurs origines de réflexions sur des concepts génériques du timbre. 1) Halocline : combinaisons de timbres – l’orchestration traditionnelle; 2) Le mot juste : emprunt de la structure du syntagme « le mot juste » pour la gestion du timbre – la phonétique; 3) Profondeurs de champ : catégorisation de timbres – les techniques instrumentales avancées.

Abstract:

Cette thèse vise à fournir une classification des homéomorphismes pseudo-Anosov généralisés jusqu'à la conjugaison topologique en utilisant une approche algorithmique. Cela implique l'obtention d'invariants finis et calculables pour chaque classe de conjugaison.Une partition de Markov d'un homéomorphisme pseudo-Anosov généralisé est une décomposition de la surface en un nombre fini de rectangles avec des intérieurs disjoints, de telle manière que leurs images interagissent avec n'importe quel autre rectangle de la partition de Markov le long d'un nombre fini de sous-rectangles horizontaux. Chaque homéomorphisme pseudo-Anosov généralisé a une partition de Markov, et en utilisant l'orientation de la surface, nous pouvons doter toute partition de Markov d'une géométrisation. Ce processus implique d'étiqueter les rectangles et de choisir une orientation sur les feuilles stables et instables de chacun de ces rectangles.Le type géométrique d'une partition de Markov géométrique a été défini par Bonatti et Langevin dans leur livre "Difféomorphismes de Smale des surfaces" pour classer les pièces de base de type selle des difféomorphismes structurellement stables sur les surfaces. Un type géométrique est un objet combinatoire abstrait qui généralise la matrice d'incidence d'une partition de Markov. Il prend en compte non seulement le nombre de fois où l'image d'un rectangle interagit avec un autre rectangle de la famille, mais aussi l'ordre et le changement d'orientation induit par les homéomorphismes.Cette thèse utilise le type géométrique d'une partition de Markov géométrique pour classer les classes de conjugaison des homéomorphismes pseudo-Anosov. Nos principaux résultats peuvent être résumés comme suit :Le type géométrique est un invariant complet de la conjugaison : Une paire d'homéomorphismes pseudo-Anosov généralisés est topologiquement conjuguée l'un à l'autre à travers un homéomorphisme préservant l'orientation si et seulement si ils ont des partitions de Markov géométriques avec le même type géométrique.La réalisation : Les types géométriques sont définis de manière large, et chaque type géométrique abstrait ne correspond pas nécessairement à un homéomorphisme pseudo-Anosov. Un type géométrique T est considéré comme faisant partie de la classe pseudo-Anosov s'il existe un homéomorphisme pseudo-Anosov généralisé avec une partition de Markov géométrique de type T. Notre deuxième résultat fournit un critère calculable et combinatoire pour déterminer si un type géométrique abstrait appartient à la classe pseudo-Anosov.Représentations équivalentes : Chaque homéomorphisme pseudo-Anosov généralisé a un nombre infini de partitions de Markov géométriques avec différents types géométriques. Notre troisième résultat est un algorithme permettant de déterminer si deux types géométriques dans la classe pseudo-Anosov sont réalisés par des homéomorphismes pseudo-Anosov généralisés qui sont topologiquement conjugués ou non<br>This thesis aims to provide a classification of generalized pseudo-Anosov homeomorphisms up to topological conjugacy using an algorithmic approach. This entails obtaining finite and computable invariants for each conjugacy class.A Markov partition of a generalized pseudo-Anosov homeomorphism is a decomposition of the surface into a finite number of rectangles with disjoint interiors and such that their images intersect with any other rectangle in the Markov partition along a finite number of horizontal sub-rectangles. Every generalized pseudo-Anosov homeomorphism has a Markov partition, and, using the surface's orientation, we can endow any Markov partition with a geometrization. This process involves labeling the rectangles and choosing an orientation on the stable and unstable leaves of each of these rectangles.The geometric type of a geometric Markov partition was defined by Bonatti and Langevin in their book, "Difféomorphismes de Smale des surfaces," to classify saddle-type basic pieces for structurally stable diffeomorphisms on surfaces. A geometric type is an abstract combinatorial object that generalizes the incidence matrix of a Markov partition. It takes into account not only the number of times the image of a rectangle intersects with any other rectangle in the family but also the order and change of orientation induced by the homeomorphisms.This thesis employs the geometric type of a geometric Markov partition to classify the conjugacy classes of pseudo-Anosov homeomorphisms. Our main results can be summarized as follows:The geometric type is a complete invariant of conjugation: A pair of generalized pseudo-Anosov homeomorphisms is topologically conjugate to each other through an orientation-preserving homeomorphism if and only if they have geometric Markov partitions with the same geometric type.The realization: Geometric types are defined broadly, and not every abstract geometric type corresponds to a pseudo-Anosov homeomorphism. A geometric type T is considered part of the pseudo-Anosov class if there exists a generalized pseudo-Anosov homeomorphism with a geometric Markov partition of geometric type T. Our second result provides a computable and combinatorial criterion for determining whether an abstract geometric type belongs to the pseudo-Anosov class.Equivalent representations: Every generalized pseudo-Anosov homeomorphism has an infinite number of geometric Markov partitions with different geometric types. Our third result is an algorithm for determining whether two geometric types in the pseudo-Anosov class are realized by generalized pseudo-Anosov homeomorphisms that are topologically conjugated or not

Abstract:

Ce mémoire traite globalement de l'influence de la musique populaire sur la création de nouvelles musiques d'art, et plus spécifiquement de l'influence du true norwegian black metal (TNBM) sur quatre de mes compositions récentes. Dans la première partie du chapitre I, nous exposons les aspects musicaux et extramusicaux des principales périodes du black metal afin de bien comprendre la genèse du TNBM. Dans la seconde partie du chapitre I, nous abordons spécifiquement le TNBM de la même façon. Dans le chapitre II, nous démontrons concrètement, à l'aide de plusieurs exemples, les modes d'influence des musiques du TNBM sur les quatre musiques à l'étude. Ces types d'influence sont au nombre de cinq : les caractères propres au TNBM, ses caractéristiques structurelles, les techniques d'écriture employées, la gestion des hauteurs et les techniques instrumentales typiques. Je dresse un portrait sommaire en conclusion des enjeux importants de ma musique à venir : la musique de timbre et l'accessibilité de la musique d'art à un large public.

Due to this position, necessary that is done there are discussions that relates this activity to the environmental preservation, aiming avoid, among others problems, irreparable damages to the mangroves ecosystem and modification in the water quality of the rivers that receive effluent of the ponds.In this sense the metals behavior comprehension in natural waters is indispensable. Some metals besides being essential nutritious, also are toxic to the aquatic organisms. And, they constitute in an agent polluter, in potential. In this context, in this work, were collected waters of a tank of species marine shimp cultivation Litopenaus vanamei, located in the district of Santa Rita, estuary area of the Ribeira river, in Paraiba state. Due to the contribution of the metals Cu, Fe and Zn in the column of water of the creation tanks, it tried to evaluate the contribution of each one of the metallic species. Like this, for seven months, samples of water of the shrimp pound were collected and separate in the fractions: (A) soluble fraction (filtered through membrane 0,45 μm); (B) labile fraction (extraction to cold of the particulate matter); (C) total fraction (extrated by acid under heating of the particulate matter). In addition to the quantity of metals, they were determined the variations of OD (Dissolved Oxygen), SPM Suspended Particulate Matter, Salinity, pH and Temperature. By observing the obtained data, about the pH influence and OD on the metals partitioning one verifies that OD in the partition of the metals, OD is more correlated with the fractions A and B of Fe and Zn, while the pH influences more the fraction C of all the metals. So much SPM, Salinity and the partitioning of the metals enhanced differences among the months, but no so significantly in the heights of water column. Besides, it was also observed correlation among fraction C of Zn and Salinity, and in smaller extension, among fraction C of Fe and this parameter. Before the high complexity and specificity of the waters of shrimp cultivation, owed to the presence of the natural aquatic biotic (phyto and zooplankton), the ration composition (proteins, vitamins, micronutrients, etc.) in addition to the peculiarities of the estuary waters, they turn the creation tanks, extremely dynamic and atypical systems<br>O Brasil é atualmente um dos principais produtores de camarão marinho do mundo. Devido a esta posição, faz-se necessário que haja discussões relacionando esta atividade à preservação ambiental, visando evitar, entre outros problemas, danos irreparáveis ao ecossistema manguezal e alteração na qualidade das águas dos rios que recebem os efluentes dos viveiros. Neste sentido a compreensão do comportamento dos metais em águas naturais é indispensável. Alguns metais além de serem nutrientes essenciais, podem ser também tóxicos aos organismos aquáticos. Constituem-se em um agente poluidor, em potencial. Neste contexto, para este trabalho, foram coletadas águas de um tanque de cultivo de camarão marinho da espécie Litopenaeus vannamei, localizado no município de Santa Rita, na região estuarina do rio Ribeira, PB. Devido ao aporte de metais como Cu, Fe e Zn na coluna d água dos tanques de criação, procurou-se avaliar a contribuição de cada uma das espécies metálicas. Assim, durante sete meses, amostras de água do tanque de cultivo foram coletadas e separadas em três frações: (A) fração solúvel (filtrada através de membrana 0,45 μm; (B) fração lábil (extração a frio do material particulado); (C) fração total (extração ácida sob aquecimento do material particulado). Além do teor de metais, também foram determinadas as variações de concentração de Oxigênio Dissolvido (OD), Material Particulado em Suspensão (MPS), Salinidade, pH e Temperatura. Observando os dados obtidos, no que diz respeito à influência de pH e OD na partição dos metais, o OD está mais correlacionado com as frações A e B de Cu e Zn, enquanto o pH influencia mais a fração C de todos os metais. Tanto o MPS, Salinidade e a partição dos metais evidenciaram diferenças entre os meses, mas não tão significativamente nas alturas de coluna d água. Além disso, caracterizou-se também correlação entre fração C de Zn e Salinidade, e em menor extensão, entre fração C de Fe e o mesmo parâmetro. Diante da alta complexidade e especificidade das águas de cultivo de camarão, devidas à presença da biota aquática natural (por ex., fito e zooplâncton), à composição da ração (proteínas, vitaminas, micronutrientes, etc) aliadas às peculiaridades das águas estuarinas, tornam os tanques de criação, sistemas extremamente dinâmicos e atípicos

Abstract:

In 2010 Chung-Graham-Knuth proved an interesting symmetric identity for the Eulerian numbers and asked for a q-analog version. Using the q-Eulerian polynomials introduced by Shareshian-Wachs we find such a q-identity. Moreover, we provide a bijective proof that we further generalize to prove other symmetric qidentities using a combinatorial model due to Foata-Han. Meanwhile, Hyatt has introduced the colored Eulerian quasisymmetric functions to study the joint distribution of the excedance number and major index on colored permutations. Using the Decrease Value Theorem of Foata-Han we give a new proof of his main generating function formula for the colored Eulerian quasisymmetric functions. Furthermore, certain symmetric q-Eulerian identities are generalized and expressed as identities involving the colored Eulerian quasisymmetric functions. Next, generalizing the recent works of Savage-Visontai and Beck-Braun we investigate some q-descent polynomials of general signed multipermutations. The factorial and multivariate generating functions for these q-descent polynomials are obtained and the real rootedness results of some of these polynomials are given. Finally, we study the diagonal generating function of the Jacobi-Stirling numbers of the second kind by generalizing the analogous results for the Stirling and Legendre-Stirling numbers of the second kind. It turns out that the generating function is a rational function, whose numerator is a polynomial with nonnegative integral coefficients. By applying Stanley's theory of P-partitions we find combinatorial interpretations of those coefficients

Abstract:

碩士<br>國立中正大學<br>化學工程研究所<br>92<br>In this session, we discuss the stability analisys of systems with parametric uncertainty by using robust D-partition. Among several parametric space methods, D-partition is an applicable method in the analysis of system stability. Many people proposed some theorem in the domain of D-partition. With the characteristic polynomial of systems, D-partition subdivides controller parametric space into several subdomain. Each subdomain includes the difference kind of poles, called D-partition areas. The lines which subdivide the subdomains was called D-partition boundary. If the system has uncertain parameters, D-partition boundary will expanse to band. It is called D-partition border. To locate the boundary of the border is the key to analyze the stability of systems. The formation of the boundary of the D-partition border is enslaved to the characteristic polynomial of system. In this paper, we will derive the form of robust D-partition. It is important that how to locate the D-partition boundary rapidly. After deciding the polynomial of the boundary by using D-partition method, it could be located precisely with locus tracking methods. The kind of methods must make a choose on a starting point before tracking. If the boundary does not lap over the starting point, it can not be found. Therefore, the locus tracking method can not provide a guarantee of locating all boundary in the parametric space. To be sure that, we quote the concept of branch and bound. The concept is that the controller parametric space is subdivided into several subdomain, and exclude the subdomain which does not include the boundary. The remain subdomain repeat the procedure until the subdomain is small enough. Finally, the remain subdomain is the set of D-partition boundary. For checking whether the boundary is included in subdomain rapidly, we will use the Bernstein expansion. This kind of method specified a set of base function to make a transformation with the object function. Because of the properties of the base function, it help us to evaluate the value of object function. At last, we link up the theorem and technology of D-partition for the application of parametric uncertainty of general systems, and prove the D-partition is applicable and realizable.

However, additional node caused by incorrect area-partition will result in unpredictable errors. In this thesis, we develop a transition layer with three right-angled triangle meshes. For verification , a simple resistor will be simulated and compared to the theoretical value. Finally, we apply this transition layer to simulate the current density profile in different depths for a resistor , and to simulate PN junction characteristics.

碩士<br>國立中央大學<br>電機工程研究所<br>92<br>In this thesis, we focus on how to effectively save the required memory space when simulate a semiconductor device. We can substantially reduce the required memory space by using device partition method. So, we can increase the node numbers by taking the advantage of device partition method and get the most accurate result. We developed the Flexible Device Partition Method. By using this method, we can partition the device into several parts as we want. So it can work more efficiently, and we will apply it to 2-D and 3-D device simulation. Finally, we will use this method to simulate a transmission-gate circuit and show the advantage of T-G in circuit design.

Abstract:

碩士<br>國立中央大學<br>電機工程研究所<br>91<br>Abstract In this thesis, we focus on how to effectively save required memory space when simulate a semiconductor device. We develop four different methods to simulate semiconductor devices. First method is coupled method(CM). It requires biggest memory space in all of the methods. Second method is partial decoupled method(PDM). The memory space with PDM is less than CM. Last, we develop device-partition method. It can be divided into two different modes. One is overlapped mode, the other is unoverlapped mode. The advantage of device-partition method is that our program can be compiled without limitation by memory space. We will use these methods to simulate an n-channel MOSFET and compare simulation result. Finally, we will use these methods to simulate a CMOS circuit and compare simulation result also.

Abstract:

no<br>The interface tribo-layer (ITL) in an automotive brake friction pair is a layer of material created from transfer films, wear particles, and surface transformations between the rotor and stator. Its presence in a brake friction interface has been proven, e.g. by the existence of a temperature ‘jump’ across the friction interface. In this paper two static transient heat transfer models which force one dimensional heat flow, have been used to investigate the ITL behaviour and obtain an equivalent thermal conductance value. The ITL equivalent thermal conductance value is important as it reduces computational requirements and software restrictions encountered in the physical model of the ITL. This approach is developed into a more realistic two-dimensional coupled temperature-displacement model using commercial FEA software (ABAQUS). A newly developed relationship that utilises the contact pressure, real contact area, and the ITL equivalent thermal conductance, has been used to estimate the effective thermal conductance at the friction interface. Subsequently the effective thermal conductance relationship is combined with the 2-D coupled temperaturedisplacement model. The combination of this relationship with the 2D FE model provides a new method of heat partition prediction in brake friction pairs. Heat partition at a brake friction interface is confirmed to be neither uniform nor constant with time.<br>IMechE<br>The full text will not be made available in Bradford Scholars due to the publisher's copyright policies.
