1. AplicaÃÃo de princÃpios de qualidade de dados durante o desenvolvimento de um sistema computacional mÃdico para a cirurgia coloproctolÃgica / Application of data quality principles in the development of a computacional medical system for coloproctology surgery
Lately, many human knowledge fields use computer systems to support data management which are the foundation to the decision making process. Data Quality (DQ) is a key feature whose absence can undermine the usefulness of the information and the processes that use it. There can be found in the literature several cases of DQ problems with impact in many

2. Filtros acústicos em cristais fonônicos
In this work, we have studied the acoustic phonon wave propagation within the periodic and quasiperiodic superlattices of Fibonacci type. These structures are formed by phononic crystals, whose periodicity allows the raise of regions known as stop bands, which prevent the phonon propagation throughout the structure for specific frequency values. This p

3. Estatística não-extensiva aplicada ao cálculo do calor específico eletrônico em estruturas quasiperiódicas
Sistemas cujos espectros são fractais ou multifractais têm sido bastante estudados nos últimos anos. O entendimento completo do comportamento de muitas propriedades físicas destes sistemas ainda está longe de ser completamente efetivado devido á complexidade dos próprios sistemas. Desta maneira, novas aplicações e novos métodos de estudo dos seus e

4. Segmentação fuzzy de imagens e vídeos
Image segmentation is the process of subdiving an image into constituent regions or objects that have similar features. In video segmentation, more than subdividing the frames in object that have similar features, there is a consistency requirement among segmentations of successive frames of the video. Fuzzy segmentation is a region growing technique that as

5. Otimização no corte de tubos estruturais: aplicação na indústria aeronáutica agrícola.
The Cutting Stock Problem consists of determining the best form to cut units of material (objects in supply), producing a set of lesser units (demanded item), with specific dimensions, that are ordered through an order wallet. To minimize the loss of material this study described a method of evaluation and optimization of the process planning of the cu

6. Virtual.Prob - Ambiente virtual para auxÃlio e verificaÃÃo do aprendizado
This work presents a virtual learning environment, Virtual.Prob, whose objective is to help the student to study Probability in the discipline Statistics and Probability for Computing (ET 586). This discipline is part of the Computer Engineering and Computer Science courses at UFPE. Virtual.Prob is based on the machine learning technique known as Bayesian Ne

7. Especificação do tipo intervalar parametrizado em CASL
The interval datatype applications in several areas is important to construct a interval type reusable, i.e., a interval constructor can be applied to any datatype and get intervals this datatype. Since the interval is, of certain form, a set of elements limited for two bounds, left and right, with a order notions, then its reasonable that interval construct
