In Brazil there is a large number of people who remain missing, and a solution for the location of these people may be in the use of various camera systems that are currently used by the public, especially in main cities. We propose to evaluate the efficiency of a model of face recognition using basically two phases: training and recognition. Thus we have constituted an image database that simulates...
The developments occurring in recent years in the Information and Communication Technologies led inevitably a great effect on the operation, structure and strategy of organizations around the world, and obviously also in the tourist sector organizations. Through the Information and Communication Technologies, it is possible to reduce communication costs and operation and may increase the flexibility,...
This paper carries on with the work of developing a network lab where a set of well-known techniques have been applied in order to allow remote access. This laboratory has been proven with several groups of students during the last three years. This experience showed the need of a tool designed to let students agree among them. It was a demand from practices where the work implied big teams, and making...
In corporate environments it is common to have multiple data sources that represent the same real world entity (such as customers, suppliers, products, etc.). This situation can also occur for external data (social networks, regulatory institutions). The extraction activity has the need to decide among the available sources, how best to obtain a given data. This paper presents an architectural approach...
This paper presents the teaching innovation project which it is being developed in the field of Information and Communications Technology. This project has 6 different subprojects to be performed. It also develops the current situation that exists in our university and the objectives to be corrected by this project. The objectives to be achieved through the implementation of this project are developed...
In this work, a software package, called gHRV, and dedicated to the automatic analysis and study of the heart rate variability is presented. The software is provided with a graphical user interface, is both free and opensource, and allows to perform both spectral and nonlinear analysis of several parameters related to the cardiac rhythm. To show the ease-of use, a detailed example employing a polysomnogram...
Traditional search for a given subject, either through the use of search engines or by searching on portals to virtual libraries, proves to be a time consuming and inaccurate task. In general, this conventional type of search only covers HTML pages/results. The lack of standards for the provision of information and search on the Internet led to the development and promotion of protocols by the OAI...
Today there is a huge growth and development of local networks and Internet, so it becomes possible to develop applications targeted for WEB as numerous benefits, some of them passing by easy accessibility and navigability. This application is the creation of a prototype system to assist diagnosis of Alzheimer's disease and its main objective to provide a rapid diagnosis through existing medical examinations...
The optical microscope is a very important tool in the teaching and learning of body tissues. However, such tool is not always available in undergraduate, graduate and, in particular, in basic education level. Thus, the creation of a Virtual Atlas of Histology, coupled with broad accessibility to the Internet, allow an alternative source of information on the construction of scientific knowledge....
Heart Rate Variability (HRV) is an emerging research field in the study of diverse pathologies, as long as it allows considering another measurement for detecting possible aggravations. The aim of this work is to study the applicability of the analysis of HRV in order to establish if a person is at risk of suffering from suicidal ideation. This work includes the development and testing of a heart...
This paper presents the use of a virtual platform based on Moodle as a supporting element for the acquisition of basic mathematical skills. The project was aimed at first engineering course students whose initial mathematical knowledge presented some shortcomings. After the use of the designed online tools, there has been an increase in pupils' confidence in their mathematical skills and their chances...
According to [1], in order to share knowledge and information it is necessary to share a set of conceptual structures within a collaborative network. Therefore, to develop an organizational information system it is required to engage in a negotiation process so that it is possible to obtain a common vocabulary. To support and improve such process, this paper presents an approach that takes advantage...
Recent technological developments in web browsers related to the ability to natively capture and process media from local devices and render 3D computer graphics, in particular due to the evolution of HTML5 and its associated APIs, such as WebGL, make it possible to provide virtual augmented reality applications directly from the web environment. In this paper we present a library for the representation...
Optical coherence tomography (OCT) is a catheter-based imaging method that employs near-infrared light to produce high-resolution cross-sectional intravascular images. In this work we propose a technique for stent strut detection in intravascular OCT images for the purpose of evaluation of neointimal coverage and stent malapposition.
The increased access of information enables a greater awareness of people with environmental and social problems, which leads to perform daily activities with less effort that requires a greater demand on the condition of the pedestrian locomotion. Planning, engineering, operation, maintenance and development of the public places are critical elements in the improvement of the people locomotion. Therefore,...
This paper describes how databases of parameterized exercises can help in the development of support materials to classes and evaluation. These databases are created in the context of project MEGUA using the software package with the same name.
In the educational activity the ideas of "educational change" and "social justice" must always be present. They are inherent in the definition of a young science, which must constantly seek new ways of bringing the curriculum to students. The change, therefore, is present in the pursuit of new methodologies. Justice, in its attempt to leverage technology to bring education teacher-student...
This paper presents and describes the implementation of an augmented reality system to assist a user in a treasure hunt gaming activity. The concept proposed here, essentially serves to support a practitioner of a form of territorial exploitation. The case study applies to global scale territories where a large number of ‘treasures’ are hidden in different locations for a subsequent hunt. The developed...
