The illuminist discourse of the digital divide: a critic to the Post-Fordist Informatic Mundaneum from Knoxville, Tennessee

This article discusses the project of the Information Society and the discourses that undergo it, as part of a political and ideological conception universalized by those countries that created and dominate computer technology, which is in turn is aligned with the Post-Fordist industrial capitalist order and its emphasis on economic accumulation and consumerism. We explain how information technology creates routines and legitimate social orders, taking for analyzes the case of the Clinton-Gore policy in the United States, when the discourse of the computer society was associated with the development and social welfare. This association is revealed in the speech made by Clinton in the city of Knoxville in year 1996. There we see the beginnings of the concern about the Digital Divide as a new form of "social disease" that prevents the passage to a better world, focused on productivity, accumulation and consumption in information-dense societies. This generates a clash between the industrial-graph-centric world and the oral-pre-industrial communities, as a result of attempting to transplant the institutional forms of the developed West. We explain the pillars of the new computerized order, and how they replaced previous epic narratives creating techno-deterministic or techno-phobic discourses in prejudice of more critical approaches. We identify the effects such deterministic discourses that connote the association between the Information Society, welfare and development, questioning the urgency of deploying this system at global level without profound critical discussion, clear goals focused on the benefit of the human beings, and the open participation of the users of the system.

[ES] Esta tesis tiene como objetivo principal conocer y diagnosticar la situación real de la informática y por extensión la de las tecnologías de la información y la comunicación (TIC) en el sistema educativo portugués, en los grados de la enseñanza preuniversitaria, teniendo como centro de atención los docentes y su perfil académico y profesional.

Per un museo virtuale dell'informatica. Un supporto automatico per creare "visite museali"

The subject of the present research is related to the field of computer technology applied to support intellectual activities such as text translation, screenwriting and content organization of popular and education courses, especially concerning museum visits. The research has started with the deep analysis of the cognitive process which characterizes a screenwriter while working. This choice has been made because a screenplay is not only an aid to the realization of a show but, more in general, it can be considered as the planning of an education, popular and formative intellectual activity. After this analysis, the research has focused on the specific area of the planning, description and introduction of topics related to the history of science, and in particular, of computer science. To focus on this area it has been fundamental to analyse subjects concerning the didactics of museum visits organization. The aim was to find out the guide lines that a teacher should follow when planning the visit of a museum (virtual museum of the history of computer science). The consequent designing and realisation of an automatic support system for the description and the production of a formative, education and popular multimedia product (for the history of computer science), has been possible thanks to the results achieved through this research. The system obtained is provided by the following features: ·management of multimedia slides (such as texts, video, audio or images) which can be classified on the bases of the topic and of the profile of the user; ·automatic creation of a sequence of multimedia slides which introduce the topic; ·management of the interaction with the user to check and give validity to the product. The most innovative aspect of the present research is represented by the fact that the product is realised on the bases of the profile of the user.

Optisch detektierte Magnetresonanz an NV-Zentren in Diamant

Die rasante Entwicklung der Computerindustrie durch die stetige Verkleinerung der Transistoren führt immer schneller zum Erreichen der Grenze der Si-Technologie, ab der die Tunnelprozesse in den Transistoren ihre weitere Verkleinerung und Erhöhung ihrer Dichte in den Prozessoren nicht mehr zulassen. Die Zukunft der Computertechnologie liegt in der Verarbeitung der Quanteninformation. Für die Entwicklung von Quantencomputern ist die Detektion und gezielte Manipulation einzelner Spins in Festkörpern von größter Bedeutung. Die Standardmethoden der Spindetektion, wie ESR, erlauben jedoch nur die Detektion von Spinensembles. Die Idee, die das Auslesen von einzelnen Spins ermöglich sollte, besteht darin, die Manipulation getrennt von der Detektion auszuführen.rn Bei dem NV−-Zentrum handelt es sich um eine spezielle Gitterfehlstelle im Diamant, die sich als einen atomaren, optisch auslesbaren Magnetfeldsensor benutzen lässt. Durch die Messung seiner Fluoreszenz sollte es möglich sein die Manipulation anderer, optisch nicht detektierbaren, “Dunkelspins“ in unmittelbarer Nähe des NV-Zentrums mittels der Spin-Spin-Kopplung zu detektieren. Das vorgeschlagene Modell des Quantencomputers basiert auf dem in SWCNT eingeschlossenen N@C60.Die Peapods, wie die Einheiten aus den in Kohlenstoffnanoröhre gepackten Fullerenen mit eingefangenem Stickstoff genannt werden, sollen die Grundlage für die Recheneinheiten eines wahren skalierbaren Quantencomputers bilden. Die in ihnen mit dem Stickstoff-Elektronenspin durchgeführten Rechnungen sollen mit den oberflächennahen NV-Zentren (von Diamantplatten), über denen sie positioniert sein sollen, optisch ausgelesen werden.rnrnDie vorliegende Arbeit hatte das primäre Ziel, die Kopplung der oberflächennahen NV-Einzelzentren an die optisch nicht detektierbaren Spins der Radikal-Moleküle auf der Diamantoberfläche mittels der ODMR-Kopplungsexperimente optisch zu detektieren und damit entscheidende Schritte auf dem Wege der Realisierung eines Quantenregisters zu tun.rn Es wurde ein sich im Entwicklungsstadium befindende ODMR-Setup wieder aufgebaut und seine bisherige Funktionsweise wurde an kommerziellen NV-Zentrum-reichen Nanodiamanten verifiziert. Im nächsten Schritt wurde die Effektivität und Weise der Messung an die Detektion und Manipulation der oberflächennah (< 7 nm Tiefe) implantieren NV-Einzelzenten in Diamantplatten angepasst.Ein sehr großer Teil der Arbeit, der hier nur bedingt beschrieben werden kann, bestand aus derrnAnpassung der existierenden Steuersoftware an die Problematik der praktischen Messung. Anschließend wurde die korrekte Funktion aller implementierten Pulssequenzen und anderer Software-Verbesserungen durch die Messung an oberflächennah implantierten NV-Einzelzentren verifiziert. Auch wurde der Messplatz um die zur Messung der Doppelresonanz notwendigen Komponenten wie einen steuerbaren Elektromagneten und RF-Signalquelle erweitert. Unter der Berücksichtigung der thermischen Stabilität von N@C60 wurde für zukünftige Experimente auch ein optischer Kryostat geplant, gebaut, in das Setup integriert und charakterisiert.rn Die Spin-Spin-Kopplungsexperimente wurden mit dem sauerstoffstabilen Galvinoxyl-Radikalals einem Modell-System für Kopplung durchgeführt. Dabei wurde über die Kopplung mit einem NVZentrum das RF-Spektrum des gekoppelten Radikal-Spins beobachtet. Auch konnte von dem gekoppelten Spin eine Rabi-Nutation aufgenommen werden.rn Es wurden auch weitere Aspekte der Peapod Messung und Oberflächenimplantation betrachtet.Es wurde untersucht, ob sich die NV-Detektion durch die SWCNTs, Peapods oder Fullerene stören lässt. Es zeigte sich, dass die Komponenten des geplanten Quantencomputers, bis auf die C60-Cluster, für eine ODMR-Messanordnung nicht detektierbar sind und die NV-Messung nicht stören werden. Es wurde auch betrachtet, welche Arten von kommerziellen Diamantplatten für die Oberflächenimplantation geeignet sind, für die Kopplungsmessungen geeignete Dichte der implantierten NV-Zentren abgeschätzt und eine Implantation mit abgeschätzter Dichte betrachtet.

Combining a Similar Coefficient Identification Algorithm with the Boundary Element Method

The boundary element method (BEM) has been applied successfully to many engineering problems during the last decades. Compared with domain type methods like the finite element method (FEM) or the finite difference method (FDM) the BEM can handle problems where the medium extends to infinity much easier than domain type methods as there is no need to develop special boundary conditions (quiet or absorbing boundaries) or infinite elements at the boundaries introduced to limit the domain studied. The determination of the dynamic stiffness of arbitrarily shaped footings is just one of these fields where the BEM has been the method of choice, especially in the 1980s. With the continuous development of computer technology and the available hardware equipment the size of the problems under study grew and, as the flop count for solving the resulting linear system of equations grows with the third power of the number of equations, there was a need for the development of iterative methods with better performance. In [1] the GMRES algorithm was presented which is now widely used for implementations of the collocation BEM. While the FEM results in sparsely populated coefficient matrices, the BEM leads, in general, to fully or densely populated ones, depending on the number of subregions, posing a serious memory problem even for todays computers. If the geometry of the problem permits the surface of the domain to be meshed with equally shaped elements a lot of the resulting coefficients will be calculated and stored repeatedly. The present paper shows how these unnecessary operations can be avoided reducing the calculation time as well as the storage requirement. To this end a similar coefficient identification algorithm (SCIA), has been developed and implemented in a program written in Fortran 90. The vertical dynamic stiffness of a single pile in layered soil has been chosen to test the performance of the implementation. The results obtained with the 3-d model may be compared with those obtained with an axisymmetric formulation which are considered to be the reference values as the mesh quality is much better. The entire 3D model comprises more than 35000 dofs being a soil region with 21168 dofs the biggest single region. Note that the memory necessary to store all coefficients of this single region is about 6.8 GB, an amount which is usually not available with personal computers. In the problem under study the interface zone between the two adjacent soil regions as well as the surface of the top layer may be meshed with equally sized elements. In this case the application of the SCIA leads to an important reduction in memory requirements. The maximum memory used during the calculation has been reduced to 1.2 GB. The application of the SCIA thus permits problems to be solved on personal computers which otherwise would require much more powerful hardware.

Some framework ideas for software engineering education

It is difficult, if not impossible, to find something that is not changing in computer technology: circuits, architectures, languages, methods, fields of application ... The "central object" itself of this brand of engineering, software, represents such a diverse reality (many objects) that the fact that it has only one name gives rise to considerable confusion. This issue, among others, was taken up by Fox (1) and, at this point, I would like to underline that it is more of a pragmatic issue than an academic one. Thus, Software Engineering Education moves in an unstable, undefined'world. This axiom governs and limits the. validity of all educational proposals in the area of Software Engineering and, thereforer all the ideas presented in this paper.

Systematic Approach for the selection of monitoring technologies in CO2 geological storage projects. Application of multicriteria decision making

Geologic storage of carbon dioxide (CO2) has been proposed as a viable means for reducing anthropogenic CO2 emissions. Once injection begins, a program for measurement, monitoring, and verification (MMV) of CO2 distribution is required in order to: a) research key features, effects and processes needed for risk assessment; b) manage the injection process; c) delineate and identify leakage risk and surface escape; d) provide early warnings of failure near the reservoir; and f) verify storage for accounting and crediting. The selection of the methodology of monitoring (characterization of site and control and verification in the post-injection phase) is influenced by economic and technological variables. Multiple Criteria Decision Making (MCDM) refers to a methodology developed for making decisions in the presence of multiple criteria. MCDM as a discipline has only a relatively short history of 40 years, and it has been closely related to advancements on computer technology. Evaluation methods and multicriteria decisions include the selection of a set of feasible alternatives, the simultaneous optimization of several objective functions, and a decision-making process and evaluation procedures that must be rational and consistent. The application of a mathematical model of decision-making will help to find the best solution, establishing the mechanisms to facilitate the management of information generated by number of disciplines of knowledge. Those problems in which decision alternatives are finite are called Discrete Multicriteria Decision problems. Such problems are most common in reality and this case scenario will be applied in solving the problem of site selection for storing CO2. Discrete MCDM is used to assess and decide on issues that by nature or design support a finite number of alternative solutions. Recently, Multicriteria Decision Analysis has been applied to hierarchy policy incentives for CCS, to assess the role of CCS, and to select potential areas which could be suitable to store. For those reasons, MCDM have been considered in the monitoring phase of CO2 storage, in order to select suitable technologies which could be techno-economical viable. In this paper, we identify techniques of gas measurements in subsurface which are currently applying in the phase of characterization (pre-injection); MCDM will help decision-makers to hierarchy the most suitable technique which fit the purpose to monitor the specific physic-chemical parameter.

Unidad de efectos de audio en Simulink

La tecnología moderna de computación ha permitido cambiar radicalmente la investigación tecnológica en todos los ámbitos. El proceso general utilizado previamente consistía en el desarrollo de prototipos analógicos, creando múltiples versiones del mismo hasta llegar al resultado adecuado. Este es un proceso costoso a nivel económico y de carga de trabajo. Es por ello por lo que el proceso de investigación actual aprovecha las nuevas tecnologías para lograr el objetivo final mediante la simulación. Gracias al desarrollo de software para la simulación de distintas áreas se ha incrementado el ritmo de crecimiento de los avances tecnológicos y reducido el coste de los proyectos en investigación y desarrollo. La simulación, por tanto, permite desarrollar previamente prototipos simulados con un coste mucho menor para así lograr un producto final, el cual será llevado a cabo en su ámbito correspondiente. Este proceso no sólo se aplica en el caso de productos con circuitería, si bien es utilizado también en productos programados. Muchos de los programas actuales trabajan con algoritmos concretos cuyo funcionamiento debe ser comprobado previamente, para después centrarse en la codificación del mismo. Es en este punto donde se encuentra el objetivo de este proyecto, simular algoritmos de procesado digital de la señal antes de la codificación del programa final. Los sistemas de audio están basados en su totalidad en algoritmos de procesado de la señal, tanto analógicos como digitales, siendo estos últimos los que están sustituyendo al mundo analógico mediante los procesadores y los ordenadores. Estos algoritmos son la parte más compleja del sistema, y es la creación de nuevos algoritmos la base para lograr sistemas de audio novedosos y funcionales. Se debe destacar que los grupos de desarrollo de sistemas de audio presentan un amplio número de miembros con cometidos diferentes, separando las funciones de programadores e ingenieros de la señal de audio. Es por ello por lo que la simulación de estos algoritmos es fundamental a la hora de desarrollar nuevos y más potentes sistemas de audio. Matlab es una de las herramientas fundamentales para la simulación por ordenador, la cual presenta utilidades para desarrollar proyectos en distintos ámbitos. Sin embargo, en creciente uso actualmente se encuentra el software Simulink, herramienta especializada en la simulación de alto nivel que simplifica la dificultad de la programación en Matlab y permite desarrollar modelos de forma más rápida. Simulink presenta una completa funcionalidad para el desarrollo de algoritmos de procesado digital de audio. Por ello, el objetivo de este proyecto es el estudio de las capacidades de Simulink para generar sistemas de audio funcionales. A su vez, este proyecto pretende profundizar en los métodos de procesado digital de la señal de audio, logrando al final un paquete de sistemas de audio compatible con los programas de edición de audio actuales. ABSTRACT. Modern computer technology has dramatically changed the technological research in multiple areas. The overall process previously used consisted of the development of analog prototypes, creating multiple versions to reach the proper result. This is an expensive process in terms of an economically level and workload. For this reason actual investigation process take advantage of the new technologies to achieve the final objective through simulation. Thanks to the software development for simulation in different areas the growth rate of technological progress has been increased and the cost of research and development projects has been decreased. Hence, simulation allows previously the development of simulated protoypes with a much lower cost to obtain a final product, which will be held in its respective field. This process is not only applied in the case of circuitry products, but is also used in programmed products. Many current programs work with specific algorithms whose performance should be tested beforehand, which allows focusing on the codification of the program. This is the main point of this project, to simulate digital signal processing algorithms before the codification of the final program. Audio systems are entirely based on signal processing, both analog and digital systems, being the digital systems which are replacing the analog world thanks to the processors and computers. This algorithms are the most complex part of every system, and the creation of new algorithms is the most important step to achieve innovative and functional new audio systems. It should be noted that development groups of audio systems have a large number of members with different roles, separating them into programmers and audio signal engineers. For this reason, the simulation of this algorithms is essential when developing new and more powerful audio systems. Matlab is one of the most important tools for computer simulation, which has utilities to develop projects in different areas. However, the use of the Simulink software is constantly growing. It is a simulation tool specialized in high-level simulations which simplifies the difficulty of programming in Matlab and allows the developing of models faster. Simulink presents a full functionality for the development of algorithms for digital audio processing. Therefore, the objective of this project is to study the posibilities of Simulink to generate funcional audio systems. In turn, this projects aims to get deeper into the methods of digital audio signal processing, making at the end a software package of audio systems compatible with the current audio editing software.

Numerical methods in Nonlinear Analysis of shell structures

The design of shell and spatial structures represents an important challenge even with the use of the modern computer technology.If we concentrate in the concrete shell structures many problems must be faced,such as the conceptual and structural disposition, optimal shape design, analysis, construction methods, details etc. and all these problems are interconnected among them. As an example the shape optimization requires the use of several disciplines like structural analysis, sensitivity analysis, optimization strategies and geometrical design concepts. Similar comments can be applied to other space structures such as steel trusses with single or double shape and tension structures. In relation to the analysis the Finite Element Method appears to be the most extended and versatile technique used in the practice. In the application of this method several issues arise. First the derivation of the pertinent shell theory or alternatively the degenerated 3-D solid approach should be chosen. According to the previous election the suitable FE model has to be adopted i.e. the displacement,stress or mixed formulated element. The good behavior of the shell structures under dead loads that are carried out towards the supports by mainly compressive stresses is impaired by the high imperfection sensitivity usually exhibited by these structures. This last effect is important particularly if large deformation and material nonlinearities of the shell may interact unfavorably, as can be the case for thin reinforced shells. In this respect the study of the stability of the shell represents a compulsory step in the analysis. Therefore there are currently very active fields of research such as the different descriptions of consistent nonlinear shell models given by Simo, Fox and Rifai, Mantzenmiller and Buchter and Ramm among others, the consistent formulation of efficient tangent stiffness as the one presented by Ortiz and Schweizerhof and Wringgers, with application to concrete shells exhibiting creep behavior given by Scordelis and coworkers; and finally the development of numerical techniques needed to trace the nonlinear response of the structure. The objective of this paper is concentrated in the last research aspect i.e. in the presentation of a state-of-the-art on the existing solution techniques for nonlinear analysis of structures. In this presentation the following excellent reviews on this subject will be mainly used.

Lo intermedio como lugar : lo intersticial, lo fronterizo y lo impreciso en la arquitectura contemporánea

1. Nuestra investigación se centra en el estudio de los “ámbitos o espacios intermedios” en momentos de la arquitectura contemporánea, en un período de transición entre finales de los años 80 y nuestros días. Pretendemos analizar cómo se presenta el ámbito intermedio en el objeto o lugar arquitectónico y su función o relación con el entorno cercano, desde el proyecto hasta su repercusión en la experiencia vivida. 2. El concepto de intermedio entendido como ámbito o espacio intersticial, fronterizo y ambivalente (o multivalente), atraviesa en la presente investigación el campo de la etimología, de la ciencia, del pensamiento y del arte, para detenerse en la arquitectura actual, llevándose a cabo una indagación concreta en el proceso de concepción, en la propuesta formal, espacial y funcional, así como en la percepción y demás experiencias o vivencias en el lugar arquitectónico. 3. En primer lugar nos proponemos estudiar y explorar el concepto de “intermedio” en sus características, funciones y ubicaciones dentro de la cultura contemporánea, detectando sus antecedentes culturales más importantes, para a continuación aplicarlo reflexivamente a obras significativas de arquitectura. La investigación se enfoca en la modalidad figural (imprecisa) de lo intermedio (en alusión al “figural” deleuziano), cuyas metáforas base son lo translúcido, la penumbra y la espuma, vinculadas al actual paradigma cultural de la complejidad (C. Jencks). A continuación se analizan las relaciones o implicaciones de dicha modalidad figural en obras de arquitectos como Eisenman, Holl, Tschumi, Ito, Fujimoto, Van Berkel y Bos, y Siza, comprobando su valor operativo y poniendo de manifiesto su sentido e importancia en la actualidad y en la disciplina. El estudio tiene como trasfondo el concepto de in-between de la obra de Eisenman, y utiliza conceptos de la filosofía del límite de Trías como algunos de sus principales fundamentos. 4. En cada una de las obras de arquitectura presentadas esta modalidad imprecisa se traduce en un ámbito o espacio intermedio figural específico. Son obras en las que real y virtual, matricial y objetual, arquitectura y territorio, existente y nuevo, colectivo e individual, social e íntimo, interior y exterior, y demás usos y funciones se entrelazan o funden. Son arquitecturas cuya geometría ya no se encuentra tan determinada por aspectos bi o tridimensionales del dibujo o de la construcción. A través de la manipulación de estas geometrías más o menos complejas, dinámicas e intersticiales, estas obras reflejan (o intuyen) las premisas del actual Zeitgeist: un cambio de esquemas de objetos a relaciones basado en un pensamiento más holístico, transdisciplinar, sistémico o complejo (E. Morin), y una nueva conciencia colectiva sobre la realidad que anuncia la crisis de la percepción, el cambio de paradigma y nuevos valores (F. Capra). Emerge otra forma de sentir y percibir el mundo, los lugares y los espacios, que poco a poco está cambiando el modo de pensar y dibujar la arquitectura, y consecuentemente de interaccionar con ella. 5. El sentido del espacio intermedio figural, emerge en las cada vez más complejas cualidades morfológico-espaciales y funcionales de una parte importante de la arquitectura actual. Arquitectura, geometría y tecnología informática están más entrelazadas que nunca, y de un modo más libre, para así poder indagar en nuevas formas de pensar y crear lugares en que los “espacios intermedios” que investigamos son un testimonio. El espacio arquitectónico se vuelve afectivo e interactivo, un lugar intermedio figural, formalizado por espacialidades intersticiales que parecen aludir a lo líquido, donde la forma es más matriz que configuración, el espacio más espacialidad que compartimiento, la función más versátil y multivalente que específica o autónoma, y la perplejidad, la imaginación y la evocación se entrecruzan y vuelven patentes. 6. La arquitectura de los lugares intermedios valora no solamente el “plano”, la “configuración” y la “transparencia”, sino sobre todo el “espacio” y la “relación” en sus interrelaciones con los usuarios y demás contextos. De la identidad a la relacionalidad, de la representación a la presentación, es una arquitectura que propone “otros espacios” que más que espacios son topografías y espacialidades intersticiales, de tensión, transición, transformación, relación, intercambio e interacción. Son lugares intermedios reales y virtuales, que se sirven tanto de la morfología como de la topología para conquistar nuevas espacialidades, pretendiendo salir de la estricta operación de “forming”/”morphing”/formación/”conformación” para explorar la de “spacing”/espaciamiento. Son lugares que se basan en conceptos como la zona de indiscernibilidad de Deleuze, la imagen- flujo de Buci-Glucksmann, la suspensión-entre de Sloterdijk, o el espacio no-objetivo al que se refiere José Gil, plasmándose en la arquitectura contemporánea como tropos de lo intersticial. 7. Son los lugares intermedios de la arquitectura actual, de espacialidad háptica, más “afectiva”, generativa e interactiva, donde ese ámbito intermedio transforma y es transformado, “afecta”, “con-mueve” (nos hace mover/accionar) y evoca otros lugares, otras posibilidades de espacio habitable u ocupable. Emerge lo intermedio como lugar, algo que anuncia y exhibe, de manera paradigmática y manifiesta, el monumento de Eisenman en Berlín. ABSTRACT 1. Our research focuses on the study of “in-between spaces or environments” at particular times in contemporary architecture, in a transition period from the end of the 1980’s through to today. We aim to analyse how in-between environments are presented in the architectural object or place and their function or their relationship with the nearby surroundings, from the project through to the experience had. 2. In this research, the in-between concept, understood as an interstitial, border and ambivalent (or multi-purpose) environment or space, is assessed from the viewpoint of etymology, science, thought and art, to conclude in current architecture, with specific exploration of the conception process, of the formal, spatial and functional proposal, together with the perception and other experiences in the architectural place. 3. Firstly, we aim to study and explore the “in-between” concept as regards its features, functions and locations within contemporary culture, revealing its most important cultural background, to then apply it reflexively to important works of architecture. The research focuses on the figural (imprecise) mode of in-between (in allusion to Deleuze’s “figural” approach) whose base metaphors are the translucent, semi-darkness and foam, linked to the current cultural paradigm of complexity (C. Jenks). We then go on to assess the relationships or implications of said figural mode in architectural works by Eisenman, Holl, Tschumi, Ito, Fujimoto, Van Berkel and Bos, and Siza, verifying their operational worth and revealing their meaning and importance today and in this discipline. The backdrop of the study is the in-between concept of Eisenman’s work and it also uses concepts from the philosophy of the limit of Trías as its main underpinnings. 4. In each of the architectural works presented, this imprecise mode is translated into a specific in-between environment or space. They are works in which real and virtual, matricial and objectual, architecture and territory, existing and new, collective and individual, social and intimate, interior and exterior and other uses and functions all intertwine or blend together. They are architectures the geometry of which is not so much determined by bi- or tri-dimensional aspects of the drawing or construction. Through the manipulation of these more or less complex, dynamic and interstitial geometries, these works reflect (or insinuate) the premises of the current Zeitgeist: A change in the scheme of objects to relationships towards a more holistic, transdisciplinary, systemic or complex thought (E. Morin), and a new collective conscience about the reality which announces the crisis of perception, the change in paradigm and new values (F. Capra). Another way of feeling and perceiving the world, places and spaces, which little by little is changing the way of thinking and drawing architecture and hence of interacting with it. 5. The meaning of figural in-between space emerges in the increasingly complex, morphological-spatial and functional qualities of a large part of architecture today. Architecture, geometry and computer technology are more than ever intertwined in a freer way to inquire into other ways of thinking and making places, where the “in-between” spaces we research are a testimony. Architectural space becomes affective and interactive, a figural in-between place, formed by interstitial spatiality which seems to allude to something liquid, where shape is more matrix than configuration, space more spatiality than compartment, its function more versatile and multi-purpose than specific or autonomous, and perplexity, imagination and evocation criss-cross each other, becoming obvious. 6. The architecture of in-between places values not only “flat”, “configuration” and “transparency”, but above all “space” and the “relationship” in its interrelations with users and other contexts. From identity to relationality, from representation to presentation, it is an architecture that proposes “other spaces”, which more than spaces are topographies and interstitial spatialities, of tension, transition, transformation, relation, exchange and interaction. They are real and virtual in-between places, that take in both morphology and topology to conquer new spatialities, aiming to depart from the strict “forming”/”morphing” operation in order to explore “spacing”. They are places that derive both from Deleuze’s indiscernibility zone concept, from Buci-Glucksmann´s image-flow concept, from Sloterdijk’s suspension-between, and from the non-objective space referred to by José Gil, and they are embodied in contemporary architecture as tropes of the interstitial. 7. They are the in-between places in architecture today, of haptic spatiality, more “affective”, generative and interactive, where that in-between environment transforms and is transformed, “affects”, “moves” (it makes us move/act) and evokes other places, other possibilities of habitable or occupiable space. The in-between emerges as a place, which paradigmatically and declaredly, Eisenman´s monument in Berlin announces and exhibits. RESUMO 1. A investigação centra-se no estudo dos “âmbitos ou espaços intermédios” em momentos da arquitectura contemporânea, no período de transição entre os finais dos anos 80 e os nossos dias. Pretende-se analisar como se apresenta o âmbito intermédio no objecto ou lugar arquitectónico e sua função ou relação com o meio envolvente, desde o projecto até à sua repercussão na experiencia vivenciada. 2. O conceito de intermédio entendido como âmbito ou espaço intersticial, fronteiriço e ambivalente (ou multivalente), atravessa na presente investigação o campo da etimologia, da ciência, do pensamento e da arte, para deter-se na arquitectura actual, realizando-se uma indagação concreta no processo de concepção, na proposta formal, espacial e funcional, assim como na percepção e demais experiencias ou vivencias no lugar arquitectónico. 3. Em primeiro lugar, explora-se o conceito de “intermédio” nas suas características, funções e concretizações na cultura contemporânea, detectando os seus antecedentes culturais mais importantes, para em seguida aplicá-lo reflexivamente a obras significativas de arquitectura. A investigação centra-se na modalidade figural (imprecisa) do intermédio (alusão ao figural deleuziano) cujas metáforas base são o translúcido, a penumbra e a espuma, relacionadas com o actual paradigma da complexidade (C. Jencks). Em seguida analisam-se as relações ou implicações da referida modalidade figural em obras de arquitectos como Eisenman, Holl, Tschumi, Ito, Fujimoto, Van Berkel e Bos, e Siza, como modo de comprovar o seu valor operativo e revelar o seu sentido e importância na actualidade e na disciplina. O estudo tem como referencia o conceito de in-between da obra de Eisenman, e utiliza conceitos da filosofia do limite de Trias como alguns dos seus principais fundamentos. 4. Em cada uma das obras de arquitectura apresentadas esta modalidade imprecisa traduz-se num âmbito ou espaço intermédia figural especifico. São obras nas quais real e virtual, matricial e objectual, arquitectura e território, existente e novo, colectivo e individual, social e intimo, interior e exterior, e outros usos e funções se entrelaçam ou fundem. São arquitecturas cuja geometria já não está tão determinada por aspectos bi ou tridimensionais do desenho ou da construção. Através do uso destas geometrias mais ou menos complexas, dinâmicas e intersticiais, estas obras reflectem (ou intuem) as premissas do actual zeitgeist: uma mudança de esquemas de objectos a relações para um pensamento mais holístico, transdisciplinar, sistémico ou complexo (E. Morin) e uma nova consciência colectiva sobre a realidade, que anuncia a crise da percepção, a mudança de paradigma e novos valores (F. Capra). Emerge uma outra forma de sentir e perceber o mundo, os lugares e os espaços, que gradualmente vai alterando o modo de pensar e desenhar a arquitectura, e consequentemente de interagir com ela. 5. O sentido do espaço intermédio figural, emerge nas cada vez mais complexas qualidades morfológico-espaciais e funcionais de uma parte importante da arquitectura actual. Cada vez mais, arquitectura, geometria e tecnologia informática, relacionam-se de um modo mais livre para indagar outras formas de pensar e fazer lugares, onde os espaços intermédios que investigamos são um testemunho. O espaço arquitectónico torna-se afectivo e interactivo, um lugar intermédio figural, formalizado por espacialidades intersticiais que parecem aludir ao estado liquido, onde a forma é mais matriz que configuração, o espaço mais espacialidade que compartimento, a função mais versátil e multivalente que especifica ou autónoma, e a perplexidade, a imaginação e a evocação entrecruzam-se e tornam-se patentes. 6. A arquitectura dos lugares intermédios valoriza não só o “plano”, a “configuração” e a “transparência”, mas sobretudo o” espaço” e a ”relação” nas suas inter-relações com os utentes e restante contextos. Da identidade à relacionalidade, da representação à apresentação, é uma arquitectura que propõe “outros espaços”, que além de espaços são topografias e espacialidades intersticiais, de tensão, transição, transformação, relação, intercambio e interacção. São lugares intermédios reais e virtuais que utilizam tanto a morfologia como a topologia para conquistar novas espacialidades, pretendendo ultrapassar a estrita operação de “forming”/“morphing”/formação para explorar a de “spacing”/espaçamento. São lugares que se apoiam tanto no conceito de zona de indescernibilidade de Deleuze, como na de imagem-fluxo de Buci-Glucksmann como no de suspensão–entre de Sloterdijk ou de espaço-não objectivo que refere José Gil, e se plasmam na arquitectura contemporânea como tropos do intersticial. 7. São os lugares intermédios da arquitectura actual, de espacialidade háptica, mais “afectiva”, generativa e interactiva, onde esse âmbito intermédio transforma e é transformado, “afecta”, ”co-move “(nos faz mover/agir) e evoca outros lugares, outras possibilidades de espaço habitável ou ocupável. Emerge o intermédio como lugar que, paradigmática e manifestamente, o monumento de Eisenmann em Berlim, anuncia e exibe.
