Повний текст джерелаENGLISH ABSTRACT: The field of topic spotting in conversational speech deals with the problem of identifying "interesting" conversations or speech extracts contained within large volumes of speech data. Typical applications where the technology can be found include the surveillance and screening of messages before referring to human operators. Closely related methods can also be used for data-mining of multimedia databases, literature searches, language identification, call routing and message prioritisation. The first topic spotting systems used words as the most basic units. However, because of the poor performance of speech recognisers, a large amount of topic-specific hand-transcribed training data is needed. It is for this reason that researchers started concentrating on methods using phonemes instead, because the errors then occur on smaller, and therefore less important, units. Phoneme-based methods consequently make it feasible to use computer generated transcriptions as training data. Building on word-based methods, a number of phoneme-based systems have emerged. The two most promising ones are the Euclidean Nearest Wrong Neighbours (ENWN) algorithm and the newly developed Stochastic Method for the Automatic Recognition of Topics (SMART). Previous experiments on the Oregon Graduate Institute of Science and Technology's Multi-Language Telephone Speech Corpus suggested that SMART yields a large improvement over ENWN which outperformed competing phoneme-based systems in evaluations. However, the small amount of data available for these experiments meant that more rigorous testing was required. In this research, the algorithms were therefore re-implemented to run on the much larger Switchboard Corpus. Subsequently, a substantial improvement of SMART over ENWN was observed, confirming the result that was previously obtained. In addition to this, an investigation was conducted into the improvement of SMART. This resulted in a new counting strategy with a corresponding improvement in performance.
AFRIKAANSE OPSOMMING: Die veld van onderwerp-herkenning in spraak het te doen met die probleem om "interessante" gesprekke of spraaksegmente te identifiseer tussen groot hoeveelhede spraakdata. Die tegnologie word tipies gebruik om gesprekke te verwerk voor dit verwys word na menslike operateurs. Verwante metodes kan ook gebruik word vir die ontginning van data in multimedia databasisse, literatuur-soektogte, taal-herkenning, oproep-kanalisering en boodskap-prioritisering. Die eerste onderwerp-herkenners was woordgebaseerd, maar as gevolg van die swak resultate wat behaal word met spraak-herkenners, is groot hoeveelhede hand-getranskribeerde data nodig om sulke stelsels af te rig. Dit is om hierdie rede dat navorsers tans foneemgebaseerde benaderings verkies, aangesien die foute op kleiner, en dus minder belangrike, eenhede voorkom. Foneemgebaseerde metodes maak dit dus moontlik om rekenaargegenereerde transkripsies as afrigdata te gebruik. Verskeie foneemgebaseerde stelsels het verskyn deur voort te bou op woordgebaseerde metodes. Die twee belowendste stelsels is die "Euclidean Nearest Wrong Neighbours" (ENWN) algoritme en die nuwe "Stochastic Method for the Automatic Recognition of Topics" (SMART). Vorige eksperimente op die "Oregon Graduate Institute of Science and Technology's Multi-Language Telephone Speech Corpus" het daarop gedui dat die SMART algoritme beter vaar as die ENWN-stelsel wat ander foneemgebaseerde algoritmes geklop het. Die feit dat daar te min data beskikbaar was tydens die eksperimente het daarop gedui dat strenger toetse nodig was. Gedurende hierdie navorsing is die algoritmes dus herimplementeer sodat eksperimente op die "Switchboard Corpus" uitgevoer kon word. Daar is vervolgens waargeneem dat SMART aansienlik beter resultate lewer as ENWN en dit het dus die geldigheid van die vorige resultate bevestig. Ter aanvulling hiervan, is 'n ondersoek geloods om SMART te probeer verbeter. Dit het tot 'n nuwe telling-strategie gelei met 'n meegaande verbetering in resultate.

Повний текст джерелаThe master's dissertation consists of an introduction, three chapters, conclusions to each chapter, general conclusions, and list of references that includes 100 points and 4 applications. The paper amounts to 223 pages. One of the current issues of modern linguistics is the study of the relation of a language and culture since the language is a mirror of the culture, which reflects the social consciousness, lifestyle, traditions, morals, the system of values and worldview. In the world, particularly in the English-speaking countries, a new cultural and linguistic phenomenon "political correctness" has gained immense popularity over the last decades. The significant topicality is presented by the interest in the study of politically correct vocabulary in modern English, which, in its turn, is explained by the fast-growing processes of globalization and international integration and cooperation in society. The theoretical basis of our research includes the theories and statements developed by modern domestic and foreign linguists and translators: M. Bauman, S. G. Ter-Minasova, O. B. Sinkevich, V. B. Velikoroda, T. R. Kiyak, O. V. Zavadskaya, S. S. Trofimova, J. S. Bondaruk, R. Y. Vishnevsky, T. Lewisohn, D. Gerrod, M. G. Komlev, and F. Beckwith. The object of the study is politically correct terms in English media texts. The subject of the study is linguocultural and pragmatic peculiarities of the functioning and translation of politically correct terms in English media texts. The aim of the research is to study the functional features of politically correct terms in English media texts and ways of their translation in Ukrainian with regard to the linguocultural differences. Achieving this goal involves the solution of the following tasks: 1) to determine socio-cultural preconditions of occurrence of the phenomenon of political correctness and consider political correctness as a linguistic phenomenon; 2) to study the features of the general notion of "media text"; 3) to substantiate the use of politically correct language in the English media text; 4) to classify the politically correct units and their functional purpose in English media texts; 5) to analyze the ways of English politically correct terms translation in Ukrainian. The scientific novelty of the dissertation research lies in the comprehensive description of the politically correct units of media texts, in a detailed analysis of their translation in particular. For the first time, the pragmatic potential of the politically correct vocabulary is studied with the application of the corpus method. The practical value of the obtained results is that the dissertation enriches the research of contemporary Germanic literature with new knowledge about political correctness and its representation in modern English. The obtained results deepen the comprehension of the functioning pattern of English politically correct terms and the peculiarities of their translation into Ukrainian and can be used in the educational process, particularly in the theoretical and practical courses of the theory and practice of translation, communication and linguocultural studies (Chapter III. The Ways of translation of the politically correct terms of modern English media texts in Ukrainian). The research material amounts to 470 politically correct terms selected from 90 media texts, including The Economist, The Guardian, The Daily Mail, Princeton Info, The Washington Post, The American Prospect, The Bolton News and BBC and CNN, by a multistage sampling approach. Research methods. In this work, general (analysis, synthesis, induction, deduction, generalization) and linguistic methods are applied. Units of analysis were determined by means of a continuous sampling method. The descriptive method allowed to present the taxonomy and interpretation of politically correct units. The contextual method helped in the determination of the linguistic and extra-linguistic features of politically correct units; quantitative analysis - in the determination of the frequency of translation transformations application; corpusmethod facilitated the study of the pragmatic potential of the politically correct language in the media text, determining the lexical and semantic peculiarities of politically correct terms, and establishing modern trends in the politically correctness. The main methodological and theoretical results and conceptualities of the study were discussed at: II All-Ukrainian Student Scientific and Practical Conference "The Science of the 21st Century: Challenges, Priorities, Perspectives of Research"; IV All-Ukrainian student scientific and practical conference "Student as a subject of the process of modernization of higher education of the XXI century: visions, values, priority tasks". Publications. The main statements and results of the dissertation research are presented in 3 publications, of which: 1 article in the scientific professional edition of Ukraine, 2 - in collections of materials of all-Ukrainian scientific and practical conferences.

Повний текст джерелаThe long-lasting historical presence of Arabic-speaking groups on the Iberian Peninsula resulted in various lexical loans, often referred to as arabisms, in Spanish. The objective of this investigation has been to compare the use of these arabisms in modern colloquial Spanish with that of the 16th century. For this purpose an ordered list of the most frequent arabisms found in modern Spanish is presented and compared with a similar list of arabisms found in texts from the 16th century. The lists are based on two corpus managed by the Royal Spanish Academy. Similarities and differences between the two lists are highlighted and possible explanations for the change in popularity of the respective arabisms are discussed. In addition, calculations of the total percentage of arabisms in current and 16th century Spanish are presented. Novels from the respective periods are used as a basis for these calculations. All the chosen novels are rooted in Castile; consequently, the percentage comparison is limited to Castilian Spanish. The study adds quantitative information that currently seems to be lacking to the existing knowledge of arabisms in Spanish. The result of the investigation indicates that the frequency of arabisms in colloquial language has diminished marginally since the 16th century, whereas the number of distinct arabisms in everyday usage of Spanish has suffered a more pronounced reduction and the number of hispanoarabic roots used has decreased even more. Approximately half of the most frequent arabisms in the 16th century still maintain this position; for a majority of the arabisms that have experienced an evident increase or decrease in popularity there exist plausible explanations in the form of changes in society.

Повний текст джерелаA numerical method called Moving Particle Semi-implicit (MPS) method was developed in this study to analyze incompressible fluids. It is a particle method using a lagrangean representation without any grid. The governing equations are the Navier-Stokes equation and continuity equation for incompressible and non-viscous flow. Most of the computational fluid dynamics (CFD) methods are based on eulerian representation and use grids to describe the geometry of the simulated domain. These differences make the MPS method easier to analyze highly nonlinear phenomena as free surface with wave breaking, sloshing, slamming, etc. In previously published articles, results of physical experiments had shown good agreement with the numerical results obtained with MPS method. In the present work, results of exciting forces were compared with the results obtained with a validated program called Wave Analysis MIT (WAMIT). It had a good agreement of results between these two programs. The optimization of the neighborhood calculation function got a good economy of computational time. The greatest contribution of this study was the optimization of the linear system solver. It was made implementing in the developed code a parallelized public code called Portable, Extensible Toolkit for Scientific Computation (PETSc) that provided a good performance profit.

Повний текст джерелаManagement of information technology (IT) assets within an enterprise is necessary to control organizational costs and ensure that the necessary business requirements are supported. For over 10 years, the Navy Marine Corps Intranet (NMCI) was charged with this task in Navy and Marine Corps IT systems. With the expiration of the NMCI contract, the Marine Corps is now managing its own IT assets. To understand the scope of IT assets to enable better management, this research explores items accounted for within the master data repository, which is aiding in the migration of legacy logistics systems to GCSS-MC. These items and their associated costs are divided into categories to provide a baseline view of Marine Corps IT hardware assets. An equivalent annual cost is applied to assets to suggest a refreshment cycle for laptops, desktops, and servers. This demonstrates a method that can provide IT managers with a means of determining when an asset should be refreshed.

Повний текст джерелаThis work deals with modelling and the numerical simulation of the effects of a moving rigid body on a multiphase flow. Here more than one object is moving, or an object is moving in a complex geometry domain. So the reference frame linked to the moving body can't be used. The model is build on a multiphase diffuse interface method with mechanical equilibrium. An advection equation is added. It applies on a Level Set function used to track the moving body. Coupling terms are added to the momentum equation and to the total energy equation. These terms are made of a penalization factor and a velocity relaxation factor. This new method allows to simulate complex cases where can interact high velocity objects, shock waves and liquid / gas interfaces

Resumo: Em problemas de contato mecânico entre dois corpos elásticos, o cálculo de tensões e deformações dos componentes é de grande importância. Em casos particulares os corpos estão sujeitos a cargas normal e tangencial na presença de atrito, o qual aumenta a complexidade do problema. O estudo do fenômeno e a modelagem do problema, empregando o método dos elementos de contorno (MEC), é apresentado neste trabalho. Devido à presença de atrito e restrições de contato, esse problema torna-se um caso não linear. A não linearidade do problema foi contornada com a aplicação incremental de carga e o uso de um método de resolução de sistemas não lineares. A zona de contato é uma das variáveis do problema e pode conter estados de adesão e escorregamento, simultaneamente. Esses estados dependem dos esforços normais e tangenciais no componente e podem variar durante o processo de aplicação de carga. Dessa forma, cada incremento de carga pode perturbar em relação ao estado anterior. Portanto, o cálculo de variáveis e a atualização do sistema de equações em cada iteração é indispensável. Por este motivo, um algoritmo robusto para definição dos estados de contato é proposto. Como o sistema de equações obtido é não linear, o uso de um método numérico adequado é exigido. Para a solução deste sistema, o método de Newton foi aplicado, o qual permite a verificação do estado de contato em cada incremento. A análise é feita com o uso de elementos quadráticos contínuos, apresentando resultados contínuos e sem oscilação. A comparação dos resultados com as soluções analíticas de Hertz e Mindlin-Cattaneo mostram boa concordância
Abstract: The computation of stresses and strains on the components is of great importance, when the contact mechanics problems between two elastic bodies are analyzed. In particular cases, bodies are subjected to normal and shear loading in the presence of friction, which increases the complexity of the problem. The study of the phenomenon and modeling of the problem, using the boundary element method (BEM), are presented in this work. Due to the presence of friction and natural restrictions, this problem becomes non-linear. The non-linearity of the problem was solved with an incremental applied load and with the use of solvers to non linear systems. The contact zone can contain stick and slip states, simultaneously. These states are dependent on the normal and shear forces on the component and can vary during the application load process. Thus, each load increment can violate the previous state and therefore, the evaluation of variables and the updating of the system of equations after each iteration is indispensable For this reason, a robust algorithm for contact state definition is suggested. Since a non linear system of equations is obtained, an appropriate numerical method is required. To solve this system, Newton¿s method is applied, which allows the verification of the state of contact at each increment. The analysis is done with the use of quadratic continuous elements and provides continuous and non-oscillatory results. Comparisons of the results with the analytical solutions of Hertz and Mindlin-Cattaneo show good agreement

Повний текст джерелаVi presenterar begreppen likformig distribution och diskrepans hos talföljder på enhetsintervallet, såväl som en viktig tillämpning av diskrepans inom numerisk integration via kvasi-Monte Carlo metoden. Några fundamentala (och andra intressanta) resultat presenteras med avseende på dessa begrepp, tillsammans med några detaljerade och instruktiva exempel och jämförelser (varav några sällan presenterade i litteraturen). Vi går vidare med analytiska och numeriska undersökningar av det asymptotiska beteendet hos diskrepansen (särskilt för van der Corput-följden), såväl som för den allmänna feluppskattningen hos kvasi-Monte Carlo metoden. Utifrån upptäckterna från dessa undersökningar ger vi ett villkorligt bevis av van der Corput's sats, samt illustrerar att man genom att använda lågdiskrepanstalföljder (som van der Corput-följden) fortfarande kan uppnå tämligen snabb konvergenshastighet för kvasi-Monte Carlo metoden. Detta även för situationer där de kända teoretiska resultatet, Koksma's olikhet, är oandvändbart.

A description of the physics and geometry of meteor trail propagation is presented. Communication techniques used to exploit the phenomenon are discussed. Current MBC circuits have operational ranges of 1200 miles without relay and maintain average data rates of 60 to 150 Bits per Second(BPS). MBC is primarily limited by the physics and geometry of the propagation medium and its usefulness is bounded by its slow data rate. Within these boundaries however, several significant use of MBC are identified. Keywords: Theses. (fr)

Повний текст джерелаWe study the Wheeler-Feynman electrodynamics using a variational principle for an action functional coupled to a finite boundary value problem. For piecewise C2 trajectories, the critical point condition for this functional gives the Wheeler-Feynman equations of motion in addition to a continuity condition of partial moments and partial energies, known as the Weierstrass-Erdmann corner conditions. In the simplest case, for the boundary value problem of shortest length, we show that the critical point condition reduces to a two-point boundary value problem for a state-dependent mixed-type neutral differential-delay equation. We solve this special problem numerically using a shooting method and a fourth order Runge-Kutta. For the cases where the boundary segment has discontinuous velocities we developed a technique to solve the Weierstrass-Erdmann corner conditions and the two-point boundary value problem together. The trajectories with discontinuous velocities presupposed by the variational method were verified by numerical experiments. In a second development, for the harder case with boundaries of arbitrary length, we implemented a method of minimization with weak gradient for the variational principle quoted above. Two numerical methods were implemented in MATLAB to find solutions of the two-body electromagnetic problem. The first combines the finite element method with Newtons method to find the solutions that vanish the weak gradient. The second uses the method of steepest descent to find the solutions that minimize the action. In both methods the trajectories are approximated within a finite-dimensional space generated by a Galerkian that supports discontinuous velocities. Many tests and numerical experiments were performed to verify the convergence of the numerically calculated trajectories; also were compared the values of the functional computed numerically with some known analytical results on circular orbits.

Using a genetic criticism methodology, a database has been created in order to make an inventory of the four textual alterations (additions, deletions, substitutions and transpositions) of some pupils. Whereas previous studies have mostly associated deletions in pupil texts with a failure, quantitative and qualitative analyses performed in the present thesis suggest that deletions may reflect a genuine strategy. Finally, educational measures involving peer-review have been implemented in classes in order to study, on the one hand, peer advices about deletions and, on the other hand, the impact of these comments on the rewriting process

Abstract: Measurement of three-dimensional solids has received great attention from the scientific community due to its wide range of applications. As examples in can be mentioned industrial quality control, human body measurement applied to ergonomics and many other areas. The pertinent literature discloses several methods and techniques to carry three dimensional measurements. Moiré technique is a group of non-contact and non-destructive methods based on the more phenomena which fringes are the result of the subtraction of the grid projected onto the surface under study and the grid projected onto a reference plane. Moiré methods are yield accurate measurements if compared to other measuring systems. This work was foccused on the projection moiré technique with phase shift, and the use of two types of grids named Ronchi and sinusoidal one. Metrological errors of various techniques as compared with the moiré method have been determined as well. This work demonstrated the best performance of grid frequency variation through several practical applied to regular and irregular solids (fruits). Body dimensions were compared with convention techniques as water immersion and calypper. The application of free software such as ImageJ, RisingSun Moire, Scilab / SIP and routines was considered very useful to reach the final results

Повний текст джерелаThe main objective of the Master thesis is collocations and collocation extraction methods. The aim of the research is to analyze collocation lists extracted by statistical methods from the parallel corpus of fiction and determine the collocation equivalents. Relevance of the thesis – collocation analysis can help linguists and other language specialists choose the right collocaton extraction methods in both, English and Lithuanian, languages. What is more, understanding of collocation translation process is very important for the translation analysis and interpreters. Research consists of 5 parts. Chapter 2 presents the concept of collocation and possible collocation translation problems. The theoretical part also includes the characteristics of the four selected statistical methods: Mutual Information (MI), T-score, Dice and Log-likelihood ratio (LLR). In chapter 3, collocation lists for each language, English and Lithuanian, are extracted. The analysis reveal that T-score and LLR methods extract grammatical collocations, while MI and Dice – lexical ones. Futher in this chapter, collocation boundaries and the coefficients of each method are defined. Chapter 4 presents a list of top 200 collocations of each language and method. The methods with new collocation lists are compared in pairs according to similarity criteria - Dice with MI (lexical collocations) and T-score with LLR (grammatical). Another distribution of bigrams according to frequency is identified, and both... [to full text]

Повний текст джерелаIn terms of classical hydrodynamics, the hydrodynamic impact problem is characterized as a boundary problem with moving boundary which position must be determined simultaneously with the solution of the field equation. This feature brings difficulties to get analytical and numerical solutions. In this sense, the purpose of this work is to present a variational method technique specifically designed for the hydrodynamic impact problem of axisymmetric rigid bodies on the free surface. The solution of the nonlinear dynamic equation of the impacting motion depends on the determination of the added mass tensor and its derivative with respect to time at each integration time step. This is done through a variational method technique that leads to a second-order error approximation for the added mass if a first-order error approximation is sought for the velocity potential. This method is an example of desingularized numerical techniques, through which the velocity potential is approximated in a sub-space of finite dimension, formed by trial functions derived from elementary potential solutions, such as poles, dipoles, and vortex rings, which are placed inside the body. The potential problem of hydrodynamic impact, characterized by the dominance of inertial forces, is here formulated by assuming the liquid surface as equipotential, what allows the analogy with the infinity frequency limit in the usual free surface oscillating floating body problem. The method is applied to the vertical hydrodynamic impact of axisymmetric bodies within the so-called Generalized von Kármán Model (GvKM). In such approach, the exact body boundary condition is full-filled and the wet correction is not taken into account. Numerical results for the added mass coefficient for a family of spheroids are presented. Moreover, considerations are made on the effects of the free surface elevation for the specific case of an impacting sphere, through analytical approaches.

It is presented in this thesis, a proposal for solution of engineering problems in heat transfer area using the network simulation method (NSM - Network Simulation Method), which is to solve these problems by analogy between the thermal circuits and electrical circuits. It will be presented to validate the two-dimensional problem of heat conduction in a cylinder in which the solutions obtained by simulation with the solution analytically obtained via Technical Generalized Integral Transform will face (GITT). In the simulations makes up the body discretization study with the aim of establishing a correlation between the amount of cells (the mesh refinement) and the relationship between the radius of the size and length of the cylinder so that the problem solution of heat transfer in the body can be considered one-dimensional. A comparison will be made between the analytical response and obtained by simulation, varying the number of divisions and different relationships between beam dimensions and length of the cylinder. From the solution validated the proposed method, applying the work presented as a generic fabric prepared by the NSM and implementation PSPICE, which serves for solving many problems of heat conduction in a cylindrical geometry.
É apresentada neste trabalho de tese, uma proposta para solução de problemas de engenharia na área de transferência de calor utilizando o método de simulação de rede (NSM – Network Simulation Method), que consiste na resolução destes problemas pela analogia existente entre os circuitos térmicos e os circuitos elétricos. Nele será apresentada a validação do problema bidimensional de condução de calor em um cilindro, no qual, serão confrontadas as soluções obtidas por simulação com a solução obtida analiticamente via Técnica da Transformada Integral Generalizada (GITT). Nas simulações realizadas fazse a discretização do corpo em estudo, com o objetivo de se estabelecer uma correlação entre a quantidade de células (refinamento da malha) e a relação entre o tamanho do raio e comprimento do cilindro para que a solução do problema de transferência de calor no corpo possa ser considerada unidimensional. A comparação se dará entre a resposta analítica e a obtida por simulação, variando o número de divisões e as diferentes relações entre as dimensões raio e comprimento do cilindro. A partir da solução validada pela metodologia proposta, o trabalho apresenta como aplicação, uma malha genérica elaborada através do NSM e implementação no PSPICE, a qual serve para resolução de diversos problemas de condução de calor em geometria cilíndrica.

Повний текст джерелаThis thesis project takes part in the development of the multiparticle-multihole configuration mixing method aiming to describe the structure of atomic nuclei. Based on a double variational principle, this approach allows to determine the expansion coefficients of the wave function and the single-particle states at the same time. In this work we apply for the first time the fully self-consistent formalism of the mp-mh method to the description of a few p- and sd-shell nuclei, using the D1S Gogny interaction.A first study of the 12C nucleus is performed in order to test the doubly iterative convergence procedure when different types of truncation criteria are applied to select the many-body configurations included in the wave-function. A detailed analysis of the effect caused by the orbital optimization is conducted. In particular, its impact on the one-body density and on the fragmentation of the ground state wave function is analyzed.A systematic study of sd-shell nuclei is then performed. A careful analysis of the correlation content of the ground state is first conducted and observables quantities such as binding and separation energies, as well as charge radii are calculated and compared to experimental data. Satisfactory results are found. Spectroscopic properties are also studied. Excitation energies of low-lying states are found in very good agreement with experiment, and the study of magnetic dipole features are also satisfactory. Calculation of electric quadrupole properties, and in particular transition probabilities B(E2), however reveal a clear lack of collectivity of the wave function, due to the reduced valence space used to select the many-body configurations. Although the renormalization of orbitals leads to an important fragmentation of the ground state wave function, only little effect is observed on B(E2) probabilities. A tentative explanation is given.Finally, the structure description of nuclei provided by the multiparticle-multihole configuration mixing method is utilized to study reaction mechanisms such as electron and proton inelastic scattering on sd-shell nuclei. Although the results also suffer from the lack of collectivity, the experimental trends are well reproduced and improved by the orbital optimization

Resumo: Este projeto tem o objetivo de estudar o efeito dos principais parâmetros que afetam a solução do problema de contato entre corpos elásticos. Foi utilizado o software comercial ANSYS 11.0 para realizar as análises de contato. A influência dos principais parâmetros considerados pelo ANSYS no problema de contato, tais como a rigidez de contato normal, o limite de penetração, os algoritmos de contato e métodos de solução, é investigada no trabalho. Observou-se que a rigidez de contato normal influi diretamente na convergência e nos resultados obtidos. Foram estudados alguns exemplos com resultados conhecidos (analíticos ou numéricos) para uma comparação com a solução do ANSYS, e exemplos de maior interesse prático, como o problema de contato do olhal menor de uma biela automotiva. A partir dos casos analisados, algumas recomendações foram feitas para a escolha dos parâmetros de contato. No entanto, existem parâmetros que dependem do conhecimento do usuário ou da realização de testes preliminares, o que requer em muitas situações um maior tempo para se obter os resultados. Como alternativa, foi investigado o potencial das redes neurais para contornar esta limitação. As redes neurais foram treinadas com resultados obtidos da solução do problema de contato (penetração e variação da pressão de contato) de modelos simplificados, tendo como saída da rede a rigidez de contato normal, que é então usada para estimar a rigidez de contato normal de problemas mais complexos. Foi usada a implementação de redes neurais do software MATLAB 7.0 para o treinamento e a simulação das redes neurais
Abstract: The objective of this project is to study the effect of the main contact parameters that affect the solution of the elastic bodies contact problem. The commercial software ANSYS 11.0 was used to run the contact analysis. The influence of ANSYS main parameters in the contact problem, such as normal contact stiffness, penetration limit, contact algorithms and solvers, is investigated in this work. The normal contact stiffness acts directly in convergence and in the obtained results. Some examples with known results (analytic or numeric) were studied to be compared with ANSYS solution, and some examples of more practical interest, as the connecting rod small end contact problem, were also studied. With the analysed cases, some recommendations were done to the choice of the contact parameters. However, there are parameters that depend on the user's knowledge or it is necessary to run some preliminary tests. As an alternative, it was investigated the neural networks potential to overcome this limitation. The neural networks were trained with obtained results of the contact problem solution (penetration and contact pressure variation) of simplified models. The normal contact stiffness was used as output of the network, which was used to estimate the normal contact stiffness of more complex problems. It was used the neural network implementation of the softwareMATLAB 7.0 to the training and simulation of the neural networks

Inflexibility, failure to adapt technology, and overly regulatory processes frustrate construction industry productivity and reduce the likelihood that large infrastructure projects will be delivered on-schedule and on-budget. Divergence from entrenched project delivery methods can provide flexibility to project managers and offers advantages for improving quality, collaboration, costs, and timeliness. The objective of this research is to provide the U.S. Army Corps of Engineers (USACE) recommendations for their Project Management Business Process (PMBP). This study reviews the current state of project management in USACE, conducts a structured systems architecture analysis of the PMBP, evaluates USACE project statistics, assesses alternative project delivery methods through a literature review, and provides case studies to consider the implementation impediments of alternative methods for public and private projects. USACE serves as the nation's largest public engineering agency with responsibilities in military construction, civil works, water navigation, environmental restoration, and disaster response. This research concludes with recommendations for selecting alternative project delivery methods best-fit to meet the distinct needs of each USACE business program. Explicitly, the application of Integrated Project Delivery is best suited for highly specialized, technical projects for military construction and interagency support, but also presents contractual challenges notyet adapted for USACE. Public Private Partnerships show promise for possible future implementation in civil works projects, but require further refinement through the USACE Pilot Program. Lastly, Construction Management at Risk is the most mature alternative method for USACE, and can provide Project Managers with additional options in fast-tracking and early contractor involvement. Essentially, the flexibility of PMBP project delivery should match the vast diversity of USACE's missions.
