summary	The technology allows to center the educative process in the student. The development of the multimedia systems and Internet facilitated this change, being tools that they make possible to create an atmosphere of interactive and colaborative learning. The remote education promotes three kinds of interactions: faculty-student, students to each other and students with other dynamic electronic resources. The Histology and the Embryology are based on the study of images. We are developing to an electronic atlas of histology and embryology with pictures of histologic material captured with a digital camera and an optical microscope. The pictures (resizables and with explanatory text) are classified by tissues or systems with optative access pages and a Link to an autoevaluation multiple option type test . There is a link to an English version. The AIH makes possible an immediate access of the images and autotesting acquired knowledgements.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Methodology for the bioclimatic design: computer sustain for election of guidelines and strategies.
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 799-805
summary	After numerous studies and practical of use, field and laboratory measurements, carried out among the years 1994 and 1999, we arrived to the elaboration and presentation of a methodology for the bioclimatic design and energetically sustainable that already takes two books publications. With the support of more than 600 figures that facilitate the understanding of the concepts explained in the books and 26 computer software and databases, that are attached to the second book, the work is facilitated so that designers of buildings that have not been never in contact with a certain climate, or that they don’t have sufficiently assumed by means of the observation of the particularities of a certain climatic situation, to understand the form in that the climate influence their design, condition or determine the design solutions and averge strategies that will choose when carrying out an architecture work.

source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 377-379
summary	General outline: Typology has provided architects basic design resources in the past. Repertories have been created by comparing and establishing relations among a multiplicity of examples: these repertories have been used as the basis for new inventions. Research on type establishes the foundations for organized knowledge that can be accumulated, shared, and enriched by successive designs. We are testing our assumption that CAD is a specially adequate tool for the transformation and manipulation of type in the early stages of the design process. Goals: Our Seminar/Studio gives those who take part in it a renewed vision of type as a basic disposition that can be subject to dynamic transformations. The use of CAD will allow the participants to experiment and verify design decisions on the grounds of a systematic use of typological precedents. Methodology: Starting with definite examples of contemporary architecture and the design theory backing the examples selected, the seminar/ studio is developed in eight studio sessions, exploring different dimensions leading to the “parti”. It is meant for experienced designers, both advanced students and graduates. The first experimental seminar of two sessions took place in November 1999. A more developed version is under way in August, 2000.

title	An Interface for Sketching 3D Curves
source	ACM Symposium on Interactive 3D Graphics, pp. 17-22 (April 1999). ACM SIGGRAPH. Edited by Jessica Hodgins and James D. Foley
summary	The ability to specify nonplanar 3D curves is of fundamental importance in 3D modeling and animation systems. Effective techniques for specifying such curves using 2D input devices are desirable, but existing methods typically require the user to edit the curve from several viewpoints. We present a novel method for specifying 3D curves with 2D input from a single viewpoint. The user rst draws the curve as it appears from the current viewpoint, and then draws its shadow on the oor plane. The system correlates the curve with its shadow to compute the curve's 3D shape. This method is more natural than existing methods in that it leverages skills that many artists and designers have developed from work with pencil and paper.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

title	Generative Polymodal Music Process
source	International Conference on Generative Art
summary	We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	Environment – Urban Interface within Urban Growth
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title	Decision support model for semi-automated selection of renovation alternatives
source	Automation in Construction 8 (4) (1999) pp. 503-510
summary	The initiation of a renovation project usually involves a long process of contemplation under conditions of high uncertainty. Large organizations, that own many buildings and other facilities, can greatly benefit from a decision-support model, which can be transformed to a computerized semi-automatic tool. It will aid them develop and execute a reasonable and economical policy of rehabilitating, renovating, remodeling, or rebuilding their facilities. This paper presents a systematic four-module decision support model: (a) Preliminary survey of background conditions; (b) Evaluation and ranking of the facility's physical condition; (c) Generation of viable alternatives for rehabilitation, renovation, or reconstruction; and (d) Quantitative techno-economic comparison among the alternatives, and systematic presentation of recommendations. The paper concludes with a demonstrative example, concerning the renovation of a 25-year-old dining facility, that highlights both the practicality of the model and the benefits from utilizing it.

title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	Evaluation of Spatial Perception in Virtual Environments
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary	The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 171-175
summary	This piece proposes new strategies and pedagogic methodologies applied to the recognition and study of the subjacent measurements of the architectural projects to be created. This proposal is the product of pedagogic experience, which stems from this instructional team of the department of tri-dimensional models of electronic models. This program constitutes an elective track for the architectural major at the college of architecture, design, and urbanism of the University of Buenos Aires and housed at the CAO center. One of the requirements that the students must complete, after doing research and analytical experimentation through the knowledge that they acquired through this course, is to practice the attained skills through exercises proposed by the department in this case, the student would be required to virtually rebuild a paradigmatic architectonic piece of several sample architects. Usually at this point, students experience some difficulties when they analyze the existing documents on the plants, views, picture, details, texts, etc., That they have obtained from magazines, books, and other sources. Afterwards, when they digitally begin to generate basic measurements of the architectural work to be modeled, they realize that there are great limitations in the comprehension of the tri-dimensional understanding of the work. This issue has brought us to investigate and develop proposals of volumetric understanding of patterns through examples of work already analyzed and digitalized tri-dimensionally in the department. Through a careful study of the existent documentation for that particular work, it is evaluated which would be the paths and basis to adopt through utilizing alternative technologies to arrive at a clear reconstruction of the projected architectural work, the study gets completed by implementing the proposal at the internet site http://www.datarq.fadu.uba.ar/catedra/dorcas

summary	This research project developed an electronic library of significant buildings chosen to represent seven selected periods of Western architectural history: Egyptian (Mortuary temple of Queen Hatshepsut), Greek (Parthenon), Roman (Pantheon), Romanesque (Speyer Cathedral), Gothic (Notre Dame Cathedral), Renaissance (Tempietto), and Modern (Des Moines Art Center). All buildings were reconstructed in their original or intended forms based on plans, drawings, photographs, and historical texts. Two products were generated by this project: (1) materials to be displayed on the World Wide Web, including rendered still images for perception, movies for a visual guide, and Virtual Reality Modeling Language (VRML) models for user navigation; and (2) virtual reality (VR) models to be displayed in the C2 (an improved version of the Cave Automatic Virtual Environment or CAVE facility). The benefits of these VR models displayed on the Web and in the C2 are their easy accessibility at any time from various geographic locations and the immersive experience that enhances viewersÌ understanding of the effects of spatial proportions on form and of colors on materials.

title	Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source	New York: The Metropolitan Museum of Art
summary	The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

title	Representation and reasoning about shapes: Cognitive and computational studies in visual reasoning in design
source	C. Freksa and D. Marks (eds), Spatial Information Theory, Springer, Berlin, pp. 315-330
summary	This paper describes some recent cognitively-based and computationally-based research on representing and reasoning about shapes. The cognitive studies are based on protocol analyses of designers and indicatethat visual reasoning in design involves drawings of shapes and their relationsin the generation of unexpected results. The computational studies are concerned with the development of qualitative representations of shapesthat can be used to reason about shapes. Two representations are described: half-planes and landmark-based qualitative codes. Reasoning using these representations is presented.
