Biometrics provides a reliable authentication mechanism using physical or behavioral traits to identify users based on their natural characteristics. Fingerprint recognition is one of the most used biometrics approach, since its high accuracy and low cost make the system more affordable and acquire satisfactory results. However, fingerprint recognition is still an open problem, since false acceptance and false r...
Nowadays, technology is present in almost every work process and consequently the demand for technological resources is more and more frequent, leading to further changes in software systems, mainly due to additional maintenance requests, and, therefore, a greater number of bugs for correction. Taking into account that bug fixing is one of the factors that impacts on software quality improvement, but at the sam...
In this project, we developed an embedded system for a flight cotroller applied to quadrotor UAVs. Built with accessible components, open hardware architecture and open software, it makes possible the tests and implementation of new control algorithms by the user, setting it apart from the most common alternatives available on the market. Therefore, there is a sensoring system for capturing and recording the qua...
The Higher Education comes as an essential part to bring professional qualification and improve the quality of individuals' lives. Despite all the advantages that professional qualification has to offer, there may be mishaps during the academic life that are often not overcome by the student / individual and result in the loosing of the aimed graduation. Moreover, in a range of four / five years, the relative r...
The work present under the defined theme "The criminal organizations in the world economic order", it objectifies to analyze the expansion of the criminal transnational in the context of the globalization, phenomenon that despairs jurists and government authorities, constituting permanent trouble to States and international organisms. In the text the author discusses the world ascent of the organized crime with...
In this work, we propose fuzzy clustering methods based on a Mahalanobis-type kernel with adaptive quadratic distances de ned either by fuzzy covariance matrices that are commom to all clusters or by a fuzzy covariance matrix that can be different for each cluster. These matrices can be also full or diagonal. The Mahalanobis-type kernel functions were built from adaptive quadratic distances parameterized by sym...
The aim of this investigation relies in the possibility of establishing the enlargement of the material competence in the international criminal court. It also analyses the new world scenery, highlighting the technological revolution in the means of communication as well as the global expansion of capital ideology and its reflection on this ideology in the sovereignty of the national states. It examines the int...
In lastest years, have been noticed the growth of social interest house in Brazil. However, the lower housing conditions and environmental degradation are characteristics of most of the produced housing. Financial constraints have been the main argument to justify these deficiencies. Seeking technical solutions, concerned with regard to environmental and economic issues for the construction sector, the use of g...
The semidefinite programming techniques, which allow to work with optimization problems subject to matrix constraints, are very efficient in structural optimization applications. Using these techniques, the present dissertation presents a new numerical algorithm, the FDIPA-GSDP(3), belonging to the family FDIPA-SDP-NL, capable to solve large optimization problems. Its differential is in the formulation of a new...
In this work, we present extensions for known subtractive clustering methods. The subtractive clustering method for symbolic interval data (iSBC) as an extension of the subtractive clustering method developed by Chiu (1994), as well as the kernelbased subtractive clustering methods defined by one or two components for symbolic interval data (iKSBC1C and iKSBC2C, respectively) as extensions of a kernel-based sub...
