Due to the increased incidence of skin cancer, computational methods based on intelligent approaches have been developed to aid dermatologists in the diagnosis of skin lesions. This paper proposes a method to classify texture in images, since it is an important feature for the successfully identification of skin lesions. For this is defined a feature vector, with the fractal dimension of images through...
This paper presents the "Gestor de Coevaluación Orientado a Grupos" (GCOG, Co-evaluation Manager Focused on Groups) for Moodle, a software tool to support peer evaluation when the students are organized using Moodle's groups and groupings. The main functionalities of this Moodle module are: a view to edit of co-evaluation questionnaires, a view to show those questionnaires adapted to each...
This work presents a model of reuse process based on concept maps. The model was applied in 2011, in the instantiation of the software process institutionalized in company in southeastern Brazil. The results obtained with the application of the model were satisfactory and the maps are effective in the materialization process.
Competitiveness, market share, professional development and personal support to community action, health, culture, education and sport, are linked to a promising new market. Coupled with the development of organizations, the pressure to achieve goals more audacious, employees increasingly overwhelmed, they end up buying some disturbance in the health-related type of labor activity. The objective of...
The increase of higher education offer is a basic need of developed and emerging countries. It requires increasing and ongoing investments. The offer of higher education, by means of Distance Learning, based on the Internet, is one of the most efficient manners for the massification of this offer, as it allows ample coverage and lower costs. In this scenario, we highlight Moodle, an open and low-cost...
Chronic Obstructive Pulmonary Disease (COPD) is usually related to cardiovascular risk and sudden death. An effective tool for the diagnosis of exacerbations in COPD patients is the heart rate variability (HRV) analysis of polysomnograms, corresponding to patients which must be monitored in a clinical center. As an alternative, we present an ambulatory electrocardiography technique to control the...
In this paper we present TRHIOS: a Trust and Reputation system for HIerarchical and quality-Oriented Societies. We focus our work on hierarchical medical organizations. The model estimates the reputation of an individual, RTRHIOS, taking into account information from three trust dimensions: the hierarchy of the system; the source of information; and the quality of the results. Besides the concrete...
Spinal cord atrophy occurs in several pathologies. Measurement of atrophy patterns from magnetic resonance (MR) images improve the neurologists's understanding of these pathologies and provide reliable means to distinguish between pathologies with similar symptoms. Spinal cord measurements from MR are complicated by spinal cord curvature, patient movement, MR resolution, lack of reproducibility in...
Traditionally, context-aware applications are developed using one of the following approaches: each application communicates directly with sources of context information; applications are developed with the aid of reusable libraries for processing context information or applications have their own context models. These approaches not only require effort on the part of those who develop them, but also...
This paper seeks to identify the critical factors for implementing ERP systems and the difficulties of implementation in two banks in Mozambique. For this purpose a qualitative study was conducted in two banks, using semi structured interviews. As motivators for the implementation were identified external factors (such as regulatory changes) and internal factors (such as problems of integration of...
An implementation proposal for Moodle to support the evaluation of competencies inside a course under the European Higher Education Area. The module is focused on the continuous improvement of the learning process through a reinforcement schema. Based on the competence learning progress, this reinforcement is planned and designed according to the learning process itself.
Electronic Health Records (EHR) applications have evolved a lot in recent years taking advantage of the strong growth of information and communication technologies (ICT) in the healthcare sector. With the existence of multiple solutions to solve the problems of systemic interoperability would be expected a greater and quicker rise of these applications within, and beyond, healthcare systems. The integrated...
This paper presents a comparison between the requirements modeling KAOS (Keep All Objects Satisfied) and Mind Maps. An experimental research method was employed to perform this work. The experiment was conducted with three groups. The first two groups had members of the Universidade Tecnológica Federal do Paraná. The third one consisted of professionals working in a software development company.
This paper performs a survey on the state of the art in the security and access controls mechanisms employed by multi agent systems as a form of data transaction, with special emphasis on their security threats and how these issues are currently being tackled for multi-agent systems. In this paper we provide a brief summary of current approaches and provide comments on their relevance, implementation...
Digital libraries (DL) have had a tremendous impact on improving the accessibility of scientific and academic publications. In developing countries, they seem to be the great hope, due to the serious existing problems with the traditional publishing and distribution mechanisms and to the potential they have on enabling access to a great panoply of publications. Moreover, accessing digital libraries...
This Project aims to promote women's sports through technology platforms such as Web 3.0. To do this, a semantic search algorithm has been developed to search for news about achievements of Spanish female athletes, in Olympic and Paralympic disciplines. All collected pieces of news are processed for later viewing in a web platform.
Following the analysis of the European project EPAL — Extending Professional Active Life, we present measures that could be considered at a municipality level to combat social exclusion and loneliness of the population after his retirement, contributing to active aging, promoting and expanding the applications of e-government, and above all, promoting inclusion and developing the local economy. The...
