Proposta de sistem��tica de posicionamento estrat��gico dos materiais : o caso de uma ind��stria da cadeia automotiva

Este trabalho estuda a aplica����o de uma proposta de sistem��tica de posicionamento estrat��gico dos materiais, com estudo de caso em uam ind��stria da cadeia automotiva, afim de identificar a����es estrat��gicas de relacionamento com fornecedores, tendo em vista a rela����o risco de suprimento e a import��ncia dos materiais nos resultados da empresa. Diferente do paradigma hist��rico das rela����es de suprimentos, que tratavam os processos de aquisi����o para a maioria dos bens e servi��os da mesma forma, a segmenta����o de fornecimento direciona para o desenvolvimento de estrat��gias de suprimentos eficientes e eficazes. A aplica����o de uma Matriz de Posicionamento Estrat��gico dos Materiais permite sugerir a����es estrat��gicas segmentadas na cadeia de fornecimento como forma de contribuir na alavancagem da competitividade, agregando de valor e reduzindo custos das empresas.

Three-Dimensional Finite Element Analysis of Vertical and Angular Misfit in Implant-Supported Fixed Prostheses

Purpose: Three-dimensional finite element analysis was used to evaluate the effect of vertical and angular misfit in three-piece implant-supported screw-retained fixed prostheses on the biomechanical response in the peri-implant bone, implants, and prosthetic components. Materials and Methods: Four three-dimensional models were fabricated to represent a right posterior mandibular section with one implant in the region of the second premolar (2PM) and another in the region of the second molar (2M). The implants were splinted by a three-piece implant-supported metal-ceramic prosthesis and differed according to the type of misfit, as represented by four different models: Control = prosthesis with complete fit to the implants; UAM (unilateral angular misfit) = prosthesis presenting unilateral angular misfit of 100 pm in the mesial region of the 2M; UVM (unilateral vertical misfit) = prosthesis presenting unilateral vertical misfit of 100 pm in the mesial region of the 2M; and TVM (total vertical misfit) = prosthesis presenting total vertical misfit of 100 pm in the platform of the framework in the 2M. A vertical load of 400 N was distributed and applied on 12 centric points by the software Ansys, ie, a vertical load of 150 N was applied to each molar in the prosthesis and a vertical load of 100 N was applied at the 2PM. Results: The stress values and distribution in peri-implant bone tissue were similar for all groups. The models with misfit exhibited different distribution patterns and increased stress magnitude in comparison to the control. The highest stress values in group UAM were observed in the implant body and retention screw. The groups UVM and TVM exhibited high stress values in the platform of the framework and the implant hexagon, respectively. Conclusions: The three types of misfit influenced the magnitude and distribution of stresses. The influence of misfit on peri-implant bone tissue was modest. Each type of misfit increased the stress values in different regions of the system. INT J ORAL MAXILLOFAC IMPLANTS 2011;26:788-796

Arquitectura ��ptima: Cuatro medios pr��cticos para optimizar proyectos de arquitectura

La investigaci��n trata de mostrar cuatro acciones habitualmente empleadas al proyectar arquitectura. La tesis narra el discurso que construyen cuatro acciones como mecanismos optimizadores, fundamentales, activos y necesarios cuando creamos nuevos proyectos. En este trabajo se estudian en profundidad cuatro acciones optimizadoras a trav��s de numerosos casos de estudio. Se estudia tambi��n la presencia de estas acciones en otros campos creativos, como la biolog��a, el arte, la literatura, la filosof��a, la matem��tica o la psicolog��a de la creatividad. Se busca qu�� tienen en com��n estas cuatro acciones y se indaga sobre la posible narraci��n que construyen entre ellas. La mayor parte de los textos que constituyen este trabajo se escriben en un formato pr��ximo al del ensayo, empleando tiempos verbales presentes evitando los tiempos verbales pret��ritos o imperfectos para potenciar la acci��n a trav��s el estilo narrativo. La investigaci��n se ha realizado a partir de fuentes bibliogr��ficas existentes en numerosas bibliotecas. Se han llevado a cabo estudios de campo realizados a trav��s de entrevistas personales a interlocutores expertos, no s��lo de teor��a arquitect��nica sino tambi��n de pr��cticas constructivas, as�� como visitas a lugares ��ntimamente relacionados con el tema de investigaci��n. Se ha completado el estudio de casos con ejercicios pr��cticos realizados por el autor de esta tesis, para profundizar con la propia investigaci��n por empat��a con los autores estudiados. La investigaci��n bibliogr��fica principal se ha desarrollado en las bibliotecas de la Universidad Polit��cnica de Madrid, de la Universidad de Alicante, de la Universidad Aut��noma de Madrid, de la Universidad Europea de Madrid, de la Universidad Camilo Jos�� Cela, de la Universidad Complutense de Madrid, de la Columbia University, de la Harvard University, de la Delft University, de Heidelberg University, de la Biblioteca Central de Madrid y de la Regional de Murcia, as�� como de la del COAMU. Tambi��n se ha utilizado recursos bibliogr��ficos propios. La metodolog��a utilizada muestra desde diferentes perspectivas el problema de las acciones optimizadoras, desde obras art��sticas, pasando por ejemplos de arquitectura construida hasta ejercicios puramente intelectuales. La acumulaci��n ha sido el m��todo de obtenci��n de conocimiento de esta tesis. Se han acumulado conocimientos y posteriormente se ha profundizado, reflexionando sobre los datos que se han ido obteniendo. Al profundizar se enlazan unas pruebas con otras, hilando y ensambl��ndolas en un discurso que hace continuo y coherente la aparici��n de cada caso estudiado. Estas entidades probatorias son acciones que han sido aplicadas frecuentemente por distintas generaciones de autores que proyectan utilizando alguna de estas cuatro acciones. Partimos de una extensa bibliograf��a general y de otra espec��fica. A trav��s de citas e im��genes se muestra el repertorio de objetos y textos estudiados. Los casos de estudio seleccionados exponen los efectos que produce cada acci��n en el ejercicio del proyectar. Se ha estudiado la necesidad de cada acci��n en todas y cada una de las partes del ciclo creativo del proyecto, tanto en pr��cticas imaginadas como en construidas, de los autores que proyectan. Se citan y se interpretan las descripciones de bi��logos, soci��logos, antrop��logos, psic��logos, escritores, artistas, arquitectos, matem��ticos, ingenieros, f��sicos, m��dicos y fil��sofos en los cuales estas acciones se encuentran conscientemente incorporadas en su procedimiento de proyectar y de pensar. Por ��ltimo, hemos obtenido unos resultados adecuados a la metodolog��a empleada y a los objetivos planteados gracias a la acumulaci��n y clasificaci��n de pruebas. Los resultados se exponen a modo de discursos conclusivos con un intencionado car��cter abierto que despliega nuevas posibles nuevas v��as de investigaci��n entorno a los temas estudiados. ABSTRACT. The research seeks to show four commonly used actions in designing architecture. Thesis recounts the speech that built four actions like optimizer, fundamental, active and necessary mechanisms when we create new projects. In this work it studies in depth four optimizer actions through numerous case studies. Also, it considers the presence of these actions in other creative fields, such as biology, art, literature, philosophy, mathematics or psychology of creativity. It is intended what these four actions have in common and it explores the possible narrative constructed among them. Most of the texts that constitute this work are written in a format close to the essay, using present tenses avoiding past or imperfect tenses of enhancing the action through the narrative style. Research has been done from literature sources available in numerous libraries. Field studies have been carried out through personal interviews with expert speakers, not just of architectonic theory but also from constructive practices, as well as visits to sites closely related to the research topic. case studies with practical exercises conducted by the author of this thesis has been completed, to deepen with the own research by empathy with the studied authors. Main bibliographical investigation has been developed in the libraries of UPM, UA, UAM, UEM, the CJC, the UCM, Columbia University, Harvard University Delft University, Heidelberg University, Madrid Central Library, Regional Murcia Library and COAMU Library. Also it has been used own bibliographical resources. Methodology shows from different perspectives the problem of optimizers actions, from art, passing through examples of architecture built up to pur�� intellectual exercise. Accumulation has been the method of obtaining knowledge of this thesis. it has been accumulated knowledge and later it has been deepened, reflecting on the data that have been obtained. By deepening tests are linked with other, spinning and locking into a discourse that makes continuous and consistent the development of each case study. These evidentiary entities are actions that have been frequently applied by different generations of authors who project using some of these four stocks. We leave from an extensive general bibliography and another specific one. Through quotes and pictures it shows the repertoire of objects and texts studied. The selected study cases set out the effects that each action produces in the exercise of projecting. It has studied the need of each action in every parts of creative cycle of the project, both imagined as constructed practices, by the authors who project. It is quoted and interpreted the descriptions of biologists, sociologists, anthropologists, psychologists, writers, artists, architects, mathematicians, engineers, physicists, physicians and philosophers in which these actions are consciously incorporated into his projecting and thinking procedure. Finally, we have obtained adequate results to the used methodology and to the stated objectives through the accumulation and classification of evidence. The results are presented as conclusive speeches with an intentional open character that unfolds new possible research routes around the studied topics.

The Centro de Micro-An��lisis de Materiales (CMAM) in the Universidad Aut��noma de Madrid is carrying out an extensive research program on the processes induced by high energy heavy mass ions (SHI) on dielectric materials and their photonic applications [1?21]. A significant part of this activity constitutes a relevant contribution to the scientific program associated to the TECHNOFUSION project. It is performed in collaboration with the Instituto de Fusion Nuclear at the UPM, the CIEMAT, the Departamento de F��sica de Materiales at UAM and several other national institutions (INTA) and international laboratories (GANIL, France), Legnaro Italy, Grenoble?. The program has led to a large number of publications in reputed international journals.

HERMES: A user-friendly connectivity analysis software

The analysis of the interdependence between time series has become an important field of research, mainly as a result of advances in the characterization of dynamical systems from the signals they produce, and the introduction of concepts such as Generalized (GS) and Phase synchronization (PS). This increase in the number of approaches to tackle the existence of the so-called functional (FC) and effective connectivity (EC) (Friston 1994) between two, (or among many) neural networks, along with their mathematical complexity, makes it desirable to arrange them into a unified toolbox, thereby allowing neuroscientists, neurophysiologists and researchers from related fields to easily access and make use of them.

M��xico: partida de ajedrez. Mario Pani

Se ensaya aqu�� c��mo construye su mirada el arquitecto Mario Pani Darqui (M��xico, D.F., 1911-1993), cuya visi��n es la del jugador de ajedrez: estrat��gica, cenital y transversal, profunda y extra��ada, inci- siva y extensa, mim��tica y contrapuesta. Todo al mismo tiempo. Con base en esta reconstrucci��n de su forma de ver ���crucial para el entendimiento de la arquitectura y el urbanismo de M��xico en el si- glo XX��� se plantea una acci��n conceptual en el entorno del r��o Manzanares en Madrid. Un paisaje espiritual, silente, que a trav��s de tres situaciones radicales obliga a quien lo contempla a un ejercicio instant��neo de meditaci��n. Se ejecuta y se cartograf��a, dando como resultado una aproximaci��n sen- sible sobre c��mo intervenir en el paisaje y su registro.
