Abstract
The aim of this paper is to partially solve the problem of visualization of clusters of particles resulting from numerical methods in engineering. Two methods for removing non-visible particles from some view point of the camera were developed. These are divided depending on the [...]

The world population is continually increasing, but the Japanese population is decreasing. By 2050, the Japanese population is calculated to be close to 100 million people, and by 2060, 40% of the Japanese are estimated to be aged 65 years or more. Data show an increase in the declining [...]Abstract
Current technologies used in e-learning processes require the logging of all activities performed. These data can be used in the assessment of students, instructors and the processes themselves. However, although this wealth of data exists, it is still difficult for those who teach [...]Abstract
The authors have questioned how the semantic web search engines work and if the graphical display of the search results improves the retrieval. The types of queries that can be performed, as well as the main features of a semantic search engine, have been analyzed. A query was selected [...]Abstract
In the last two decades, data visualization has become a fundamental tool for the exploration and communication of complex messages in disciplines such as statistics, business intelligence, science, journalism, etc. This article exposes the advantages of visualization and also some [...]Abstract
Our digital world is increasingly visual. Mobile applications focused on digital photography such as Instagram are vehicles for the creation, manipulation and instant diffusion of images. Instagram is therefore an open window to research in Social Sciences and Digital Humanities, [...]Abstract
Many scientific applications deal with data from a multitude of different sources, e.g., measurements, imaging and simulations. Each source provides an additional perspective on the phenomenon of interest, but also comes with specific limitations, e.g. regarding accuracy, spatial [...]Abstract
This paper presents the current status of VU-Flow (Visualization of Users Flow), a software tool that is able to automatically record usage data in Virtual Environments and provide a set of 2D and 3D visualizations that make it easy for an evaluator to visually detect peculiar users [...]Abstract
In this paper, we present the design and implementation of POSSE, a new, lightweight computational steering system based on a client/server programming model. We demonstrate the effectiveness of this software system by illustrating its use for a visualization client designed for a [...]
