Visualisation and reconstruction in dentistry

Visualisation in the field of dentistry has nor, thus far, reached the same development as other medical fields. Potential applications of visualisation techniques in this area, however, are many, ranging from educational displays to training for delicate procedures. This paper reports on the investigation of techniques for handling three-dimensional models of teeth, aiming at investigation of dental structures. An algorithm was implemented for this purpose, which reconstructs three-dimensional teeth models from two-dimensional contour slices. Results employing various data sets are presented, including the output of VRML models for exploration.

Design & seleção de materiais: elaboração e execução de um sistema de informações para projeto do produto: madeiras

Wood is a renewable material and has unique characteristics that stem from its orthotropic properties. The objective of this study was to develop and implement an informational Selection of Materials and Manufacturing Processes appropriate to the activity of Product Design - Woods. Composed of a Digital Information System, distributed, and an ordered collection of samples. The design of a product, carries with it the choice of material, and the choice of a manufacturing process. Information on materials and manufacturing processes are available with different content, media and interfaces. However, such information is not systematized so that they can be recovered, as the need for the designer, especially on wood. This set of methods is called the Selection of Materials and Manufacturing Processes. It is hoped through this study that the methodologies for SMPF are employed by product designers, architects and engineers in Brazil.

Arte reversa: aplicando a engenharia reversa na arte

This study aimed to examine the reverse engineering and respond to a concern about the possible application of this concept in art, breaking down barriers and breaking paradigms. Using 3D scanning, the art of computer aided design and manufacturing – CAD/CAM, machining by computer numerical control - CNC, engineering, and applying this methodology in the arts especially in sculpture, it is possible to dematerialize a artwork, virtualizes it in 3D programs, make speeches, and process a new work, a new art elsewhere. By the example of surgeries at a distance, the artist, or technical author could produce their works, and materialize them anywhere. In other words, do the reverse gear. It discusses the relationship between art and technology, the role of the author, the viewer, which can interfere with the interactivity that case by stating that art, exists only in the look and feel of the viewer.

ANIMATED TRANSITION IN SIMILARITY-BASED TILED IMAGE LAYOUT

Effective techniques for organizing and visualizing large image collections are in growing demand as visual search gets increasingly popular. iMap is a treemap representation for visualizing and navigating image search and clustering results based on the evaluation of image similarity using both visual and textual information. iMap not only makes effective use of available display area to arrange images but also maintains stable update when images are inserted or removed during the query. A key challenge of using iMap lies in the difficult to follow and track the changes when updating the image arrangement as the query image changes. For many information visualization applications, showing the transition when interacting with the data is critically important as it can help users better perceive the changes and understand the underlying data. This work investigates the effectiveness of animated transition in a tiled image layout where the spiral arrangement of the images is based on their similarity. Three aspects of animated transition are considered, including animation steps, animation actions, and flying paths. Exploring and weighting the advantages and disadvantages of different methods for each aspect and in conjunction with the characteristics of the spiral image layout, we present an integrated solution, called AniMap, for animating the transition from an old layout to a new layout when a different image is selected as the query image. To smooth the animation and reduce the overlap among images during the transition, we explore different factors that might have an impact on the animation and propose our solution accordingly. We show the effectiveness of our animated transition solution by demonstrating experimental results and conducting a comparative user study.

Explotación de servicios de la Infraestructura de Datos Espaciales de España (IDEE) en dispositivos móviles

En los últimos años el número de dispositivos móviles y smartphones ha aumentado drásticamente, así como el número de aplicaciones destinadas a estos. Los desarrolladores siempre se han visto frenados en la creación de estas aplicaciones debido a la complejidad que supone la diversidad de sistemas operativos (Android, iOS, Windows Phone, etc), que utilizan lenguajes de programación diferentes, haciendo que, para poder desarrollar una aplicación que funcione en estas plataformas, en verdad haya que implementar una aplicación independiente para cada una de las plataformas. Para solucionar este problema han surgido frameworks, como Appcelerator Titanium, que permiten escribir una sola vez la aplicación y compilarla para las diferentes plataformas móviles objetivo. Sin embargo, estos frameworks están aún en estado muy temprano de desarrollo, por lo que no resuelven toda la problemática ni dan una respuesta completa a los desarrolladores. El objetivo de este Trabajo de Fin de Grado ha sido contribuir a la evolución de estos frameworks mediante la creación de un módulo para Appcelerator Titanium que permita construir de manera ágil aplicaciones multiplataforma que hagan uso de visualizadores de información geográfica. Para ello se propone el desarrollo de un módulo de mapa con soporte para capas WMS, rutas y polígonos en WKT, KML y GeoJSON. Se facilitará además que estas aplicaciones puedan acceder a capacidades del hardware como la brújula y el GPS para realizar un seguimiento de la localización, a la vez que se hace uso de la aceleración por el hardware subyacente para mejorar la velocidad y fluidez de la información visualizada en el mapa. A partir de este módulo se ha creado una aplicación que hace uso de todas sus características y posteriormente se ha migrado a la plataforma Wirecloud4Tablet como componente nativo que puede integrarse con otros componentes web (widgets) mediante técnicas de mashup. Gracias a esto se ha podido fusionar por un lado todas las ventajas que ofrece Wirecloud para el rápido desarrollo de aplicaciones sin necesidad de tener conocimientos de programación, junto con las ventajas que ofrecen las aplicaciones nativas en cuanto a rendimiento y características extras. Usando los resultados de este proyecto, se pueden crear de manera ágil aplicaciones composicionales nativas multiplataforma que hagan uso de visualización de información geográfica; es decir, se pueden crear aplicaciones en pocos minutos y sin conocimientos de programación que pueden ejecutar diferentes componentes (como el mapa) de manera nativa en múltiples plataformas. Se facilita también la integración de componentes nativos (como es el mapa desarrollado) con otros componentes web (widgets) en un mashup que puede visualizarse en dispositivos móviles mediante la plataforma Wirecloud. ---ABSTRACT---In recent years the number of mobile devices and smartphones has increased dramatically as well as the number of applications targeted at them. Developers always have been slowed in the creation of these applications due to the complexity caused by the diversity of operating systems (Android, iOS, Windows Phone, etc), each of them using different programming languages, so that, in order to develop an application that works on these platforms, the developer really has to implement a different application for each platform. To solve this problem frameworks such as Appcelerator Titanium have emerged, allowing developers to write the application once and to compile it for different target mobile platforms. However, these frameworks are still in very early stage of development, so they do not solve all the difficulties nor give a complete solution to the developers. The objective of this final year dissertation is to contribute to the evolution of these frameworks by creating a module for Appcelerator Titanium that permits to nimbly build multi-platform applications that make use of geographical information visualization. To this end, the development of a map module with support for WMS layers, paths, and polygons in WKT, KML, and GeoJSON is proposed. This module will also facilitate these applications to access hardware capabilities such as GPS and compass to track the location, while it makes use of the underlying hardware acceleration to improve the speed and fluidity of the information displayed on the map. Based on this module, it has been created an application that makes use of all its features and subsequently it has been migrated to the platform Wirecloud4Tablet as a native component that can be integrated with other web components (widgets) using mashup techniques. As a result, it has been fused on one side all the advantages Wirecloud provides for fast application development without the need of programming skills, along with the advantages of native apps, such as performance and extra features. Using the results of this project, compositional platform native applications that make use of geographical information visualization can be created in an agile way; ie, in a few minutes and without having programming skills, a developer could create applications that can run different components (like the map) natively on multiple platforms. It also facilitates the integration of native components (like the map) with other web components (widgets) in a mashup that can be displayed on mobile devices through the Wirecloud platform.

A perceptive insight into cities patterns by visualizing urban economies

Urban economic activities are an essential facet in defining city identity. Traditional approaches rely very often on the most theoretical and quantitative features of the studies, excluding de-facto a direct association between those findings and the tangible subject of the analysis. To fill the gap, the Big Data era and information visualization methodologies could help analysts, stakeholders and general audience to gain a new insight on the field. In this paper, we want to provide some food for thought about new opportunities arising in visual urban economies as well as present some visual results on possible scenarios.
