summary	From the complex perspective of modern information society, knowledge and digital culture, we have detected limitations and obsolescente levels of much of the university educational system. We consider that teaching and learning reflect a beta protoparadigm state in constant construction. We value new ideas within the limits of education, communication and transmedia aesthetics, which contribute to the visibility of innovative practices and transformations. We reflect about necessary changes in the current education, from the diversification and reinvention of the use of educational technologies to liquid infrastructures. Our intention is to contribute to the conceptual frameworks development to fit sustainable strategies and result transferences towards classroom practices known as learning ecosystems.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 167-170
summary	We present exploratory studies about 2.0 web applications linked to renewed collective curatorial activities. In particular we focus on Pinterest application, which collectively generates collection spaces centered in a strong both image and digital graphic presence. We analyze practices related to User Experience Design, which refer to all the factors linked to Interface Design, and produce positive or negative perception of the application. We use the Shedroff model (2009) exploring dimensional categories about significance, duration, amplitude, intensity, interaction and triggers or experience releasers.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	Problemática de las Modelizaciones (The Issue of Modeling)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 182-185
summary	The modelization of an architectural fact, generated through a CAD program, doesn't have only the purpose of generating a virtual electronic, but a constructive scale model of geometric nature. It also implies, a conceptualization level and a posture in front of the pattern that makes thinking in other fields besides the formally constructive, such as: the descriptive and geometric patterns, the communicational and the symbolic pattern. We should understand the way the constructive thought is done the message of the model, either for the relationship with the environment and with the human scale, depends not only upon the author, but his elections will be intrinsically related with his cultural baggage, besides its geometric, graphical and technicians data. These databases condition the result of the model, for this reason we analyzed these relationships looking for a good handling of the cultural codes, to achieve a complete communication of the model. In these moments of the "global village", we should consider this problematic as a visceral topic of the architectural representation, to achieve an effective communication, among different cultures, of the models represented.

title	The Beta2-spline : A Special Case of the Beta-spline Curve and Surface Representation
source	IEEE Computer Graphics and Applications September, 1985. vol. 5: pp. 46-58 : ill. includes bibliography.
summary	This article develops a special case of the Beta-spline curve and surface technique called the Beta2-spline. While a general Beta-spline has two parameters (B1 and B2) controlling its shape, the special case presented here has only the single parameter B2. Experience has shown this to be a simple but very useful special case that is computationally more efficient than the general case. Optimized algorithms for the evaluation of the Beta2-spline basis functions and rendering of Beta2-spline curves and surfaces via subdivision are presented. This technique is proving to be quite useful in the modeling of complex shapes. The representation is sufficiently general and flexible so as to be capable of modeling irregular curved-surface objects such as automobile bodies, aircraft fuselages, ship hulls, turbine blades, and bottles

title	A Description and Evaluation of Various 3-D Models
source	IEEE Computer Graphics and Applications. January, 1984. vol. 4: pp. 38-52 : ill. Includes bibliography
summary	The use of parametric curves and surfaces for object modeling in computer graphics is becoming increasingly popular. There is sometimes, however, a reluctance to use them because it seems that the added power they give is more than offset by the complexity of their formulations and their computations. The purpose of this article is to clarify their meanings and uses and show how much they have in common behind the diversity of their formulations. The author discusses the properties and benefits of using the parametric Hermite, Coons, Bezier, B-spline, and Beta-spline curve and surface formulations

title	About Virtual Spatial Modeling in Architectural Education
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 138-142
summary	The professional perception of the architectural space characterizes the most advanced level of the architect’s mastership. In the article the virtual modeling is regarded as an effective way of forming the professional perception of integrity of architectural space. Computer technologies bring together bi-dimensional and three-dimensional languages of modeling and thus they help the procedure of movement of consciousness from the plane to volumetric images and back to the visual and mobile. They help to carry out the level-by-level analysis of the multilevel structure of an architectural reality in the mode of active dialogue. The process of interaction of consciousness with the model becomes accessible to studying. There appears an opportunity to manage this process with the aim of forming perception.

title	An Introduction to Splines for Use in Computer Graphics and Geometric Modeling
source	Morgan Kaufmann Publishers, Los Altos, CA
summary	The most basic output primitives in every computer graphics library are "lineSegment()" and "Polygon()", ortheir equivalents. These are, of course, sufficent in the sense that any curved line or surface can be arbitrarrily well approximated by straight line segments or planar polygons, but in many contexts that is not enough. Such approximations often require large amounts of data to obtain satifactory smoothness, and they are awkward to manipulate. Then too, even with the the most sophisticated continous shading models, polygonaltechniques can resultin visually ojectionable images. Mach bands may be apparent at the borders between adjacent polygons, and there is always a telltale angularity to polygonal silhouettes. Hence many modeling systems are augmented by circles, spheres, cylinders, etc. and allow such simple primitives to be combined to form quite complex objects.

title	VDU WORK IN DIFFERENT LIGHTING CONDITIONS

summary	In order to avoid the disadvantages of purely subjective methods in a technical evaluation of daylight and artificial light systems, the Bartenbach LichtLabor developed new test methods which can determine objectively and quantitatively the visual or psycho-physiological stress connected with VDU work [1], depending on different lighting conditions. Daylight and artificial lighting systems were tested with these methods and compared by using the performances achieved by the test subjects. Some highly significant differences in performance done under the individual lighting systems became apparent and demonstrated that the visual stress or the physical or physiological fatigue from an ergonomic viewpoint depends largely on the lighting conditions at the workplace. This holds true for daylight systems (glare protection, re-directing lamellae, clear window as a control condition) as well as for purely artificial lighting systems where especially the choice of color temperature of the light and the used control gear (conventional or electronic) determine the resulting performance. Optimized lighting also positively affects the productivity and economicy for the design of workplaces that take the human factor into account.

summary	So far yet, even the most advanced technology has not been able to substitute a human, his thoughts, feelings, dreams, longings, visions. It can though, removing need for all kind of effort from our everyday life, surrounding a human with unprecedented comfort, create feeling of peace and security. Task of a computer is to provide assistance, helping in calculations, forming of refined solids, It contains a compendium of knowledge and memory - but not creative skills. So far it's only a machine, with help of which a possibility of creative expression is expanded. It only can solve problems for a human faster and more efficient way, does not have the ability to describe (formulate) problems. Even while providing a support, does it do that honestly? It means, does it support us in those of our doings where we truly need it? Computers have enormous possibilities of use that are not exploited sufficiently and all the time new generations of yet quicker machines with unbelievable power are being created. Every new type of computer appears to be obsolete and insufficient within a few months. Insufficient for what?

source	Cyber-Real Design [Conference Proceedings / ISBN 83-905377-2-9] Bialystock (Poland), 23-25 April 1998, pp. 21-26
summary	With regard to mental perception, light is one of the basic and strongest experiences influencing man. It is a phenomenon unchanged since the beginning of human kind, regardless of the fact what form or shape it was transmitted in. We are so used to light that we have stopped noticing how much we owe to it. It is the basic source and condition of our visual perception. Without light, illumination, we would not be able to see anything as it is light that transmits the shapes, distances and colours seen by us. The light which we perceive is a specific sight stimulus. It constitutes of only a small range of the spectrum of electromagnetic radiation existing in nature. The visible radiation encompasses the wave length from 400 to 800 nm. When the whole range of the visible wave spectrum enters the eye, the impression of seeing white light is produced. The light rays entering the sight receptors are subject to reflection, absorption and transmission. In the retina of the eye, the light energy is transformed into nerve impulses. The reception of light is dependent on the degree of absorption of the length of certain waves and the concentration of light. A ray of light entering the eye pupil is the proper eye stimulus which stimulates the receptors of the retina and causes visual impressions.

summary	The aim of an information retrieval system is to find information items relevant to an information need. As relevance is a kind of similarity relation between the concepts represented by the information item and those represented by the formulation of the information need, it is not astonishing to discover that the class of possible query forms -formulations of the information needs - is the same as the class of possible representations of information items.

summary	Driven by technology, this multidisciplinary research focuses on the implementation of a photomechanical material into a reactive wearable that aims to protect the body from the ultraviolet radiation deriving from the sun. In this framework, the wearable becomes an active, supplemental skin that not only protects the human body but also augments its functions, such as movement and respiration. The embedded knowledge enables the smart material to sense and exchange data with the environment in order to passively actuate a system that regulates the relation between the body and its surroundings in an attempt to maintain equilibrium. The design strategy is defined by 4 sequential steps: a) The definition of the technical problem, b) the analysis of the human body, c) the design of the reactive material system, as well as d) the digital simulations and the digital fabrication of the system. The aforementioned design strategies allow for accuracy as well as high performance optimization and predictability in such complex design tasks, enabling the creation of customized products, designed for individuals.
