1. Procesos de Visualización en una Tarea de Generación y Representación de Cuerpos de Revolución
Abstract In this work we analyzed the visualization processes involved in a mathematical task that requires generating and representing solids of revolution. The task was administered to four hundred university students from the Bachelor's Degree in Primary Education. We adopted the Ontosemiotic Approach to Mathematical Instruction and Knowledge as a theoret

2. PENETRAÇÃO E DISTRIBUIÇÃO DO CONSOLIDANTE PARALOID® B-72 EM CERÂMICA BRANCA ESTUDADA POR TOMOGRAFIA COM NÊUTRONS
The neutron tomography technique was employed to study the penetration and distribution of the consolidant Paraloid® B-72 in ceramic. This study was carried out in white contemporary ceramic vessels which were maintained in two distinct and controlled air humidity conditions, 35% and 90%, before the consolidant application (brushing technique). The results

3. Las Funciones Semióticas como Instrumento de Diagnóstico y Abordaje de Errores
Abstract Semiotic functions are theoretical and methodological tools used by the Ontosemiotic Approach of Cognition and Mathematics Instruction (OSA) to study the construction of meanings of mathematical objects. In this paper, through some examples, the use of such functions is described for dealing different problems in university students learning. From t

4. Interaction between affordance and handedness recognition: a chronometric study
The visualization of tools and manipulable objects activates motor-related areas in the cortex, facilitating possible actions toward them. This pattern of activity may underlie the phenomenon of object affordance. Some cortical motor neurons are also covertly activated during the recognition of body parts such as hands. One hypothesis is that different subpo

5. Explorando conjuntos de dados volumétricos multidimensionais variantes no tempo usando projeções / Exploring time-varying multidimensional volumetric datasets using projections
The area of volume visualization encompasses a set of techniques used for representation, manipulation and display of data associated with a region of a volume, thus enabling the exploration and understanding of the interior of three-dimensional objects. However, some limitations are still encountered in this area. For example, the simultaneous exploration o

6. Proposta de traduÃÃo dos princÃpios da coordenaÃÃo modular em parÃmetros aplicÃveis ao building information modeling. / Study for the translation of the modular coordination principles for the building information modeling parameters
Due to changes occurring in the Civil Construction scenario, it is important to emphasize the challenge to achieve the growing demand for housing and overcome deficiencies of the sector related to productivity and the reliability of the products, from design to construction. In this context, Modular Coordination and Building Information Modeling (BIM) emerge

7. Razonamiento geométrico y visualización espacial desde el punto de vista ontosemiótico
As part of an investigation on the evaluation and development of visualization skills and spatial reasoning, we present the analysis of a task used with a sample of 400 student teachers. The analysis is carried out applying the notion of configuration of objects and processes introduced in the "onto-semiotic approach" to mathematical knowledge and instructio

8. A infografia como recurso comunicacional no processo de aquisição de informação e compreensão de tipografia
This exploratory study focuses on the use potential of infographics, visualization techniques and information design to enhance access to typography. An analysis and synthesis of methods is proposed and added to experience reports that guide the creation of informational graphics, from where the idea that the construction process and not only the query use o

9. Vibroacustografia na avaliação tridimensional de artroplastia total de quadril / Vibro-acoustography in the tridimensional evaluation of total hip arthroplasty
Vibro-acoustography (VA) is a high lateral resolution (<0.7 mm), speckle-free, non- ionizing and non-invasive image based on the nonlinear combination phenomenon of ultrasound waves (MHz) that generates a narrow focus region of low frequency (kHz). In this work, we propose a VA-based tridimensional evaluation of the exposed area of implants, after total hip

10. Visualização volumétrica aplicada às Geociências
This paper is on volume visualization of spatial data. It aims at showing new possibilities to visualize three-dimensional phenomena such as geology, soils, geophysics, seismic and the like. The use of volumes in the evaluation processes allows one to visualize and to explore the phenomenon as a continuous body in space, thus incorporating the third dimensio

11. Visualização da curvatura de objetos implícitos em um sistema extensável. / Curvature visualization of implicit objects in a extensible system.
Neste trabalho, estudaremos a visualização da curvatura de superfícies definidas implicitamente por funções do tipo f:[0,1] [0,1], usando a técnica de lançamento de raios (ray casting). Como em geral conhecemos apenas valores amostrados de f, estudaremos um método de interpolação tricúbica, a fim de calcular as derivadas de segunda ordem precisame

12. Distributed environment in Virtual Reality as support the Cooperative Learning for the Problems Solving / Ambientes distribuídos em Realidade Virtual como suporte à Aprendizagem Cooperativa para a Resolução de Problemas
A great number of researchers believe that problem resolution is inherent from the great part of the teaching and learning processes. It is considered that this methodology presents a better effectiveness when applied cooperatively, in other words, an apprentice improves your acting in solving problems when accomplishes his activity in cooperation with other
