1. Pattern recognition of abscesses and brain tumors through MR spectroscopy: Comparison of experimental conditions and radiological findings
Abstract Introduction The interpretation of brain tumors and abscesses MR spectra is complex and subjective. In clinical practice, different experimental conditions such as field strength or echo time (TE) reveal different metabolite information. Our study aims to show in which scenarios magnetic resonance spectroscopy can differentiate among brain tumors,

2. Artificial neural network for prediction of the area under the disease progress curve of tomato late blight
ABSTRACT: Artificial neural networks (ANN) are computational models inspired by the neural systems of living beings capable of learning from examples and using them to solve problems such as non-linear prediction, and pattern recognition, in addition to several other applications. In this study, ANN were used to predict the value of the area under the diseas

3. An Efficient Human Identification through MultiModal Biometric System
ABSTRACT Human identification is essential for proper functioning of society. Human identification through multimodal biometrics is becoming an emerging trend, and one of the reasons is to improve recognition accuracy. Unimodal biometric systems are affected by various problemssuch as noisy sensor data,non-universality, lack of individuality, lack of invaria

4. CLASSIFICATION OF POWER QUALITY CONSIDERING VOLTAGE SAGS IN DISTRIBUTION SYSTEMS USING KDD PROCESS
In this paper, we propose a methodology to classify Power Quality (PQ) in distribution systems based on voltage sags. The methodology uses the KDD process (Knowledge Discovery in Databases) in order to establish a quality level to be printed in labels. The methodology was applied to feeders on a substation located in Curitiba, Paraná, Brazil, considering at

5. Proposing the novelty classifier for face recognition
INTRODUCTION: Face recognition, one of the most explored themes in biometry, is used in a wide range of applications: access control, forensic detection, surveillance and monitoring systems, and robotic and human machine interactions. In this paper, a new classifier is proposed for face recognition: the novelty classifier. METHODS: The performance of a novel

6. Exploiting contextual information for image re-ranking and rank aggregation in image retrieval tasks = : Explorando informações contextuais para reclassificação de imagens e agregação de listas em tarefas de recuperação de imagens / Explorando informações contextuais para reclassificação de imagens e agregação de listas em tarefas de recuperação de imagens
Content-Based Image Retrieval (CBIR) systems aims at meeting the user needs expressed in query specifications. Given a query pattern (e.g., query image) as input, a CBIR system retrieves the most similar images in a collection by taking into account image visual properties. Since users are interested in the images placed at the first positions of the returne

7. Sistema imunológico artificial para predição de fraudes e furtos de energia elétrica / Artificial immune system to predict electrical energy fraud and theft
Neste trabalho é analisada a aplicação da técnica de Sistemas Imunológicos Artificiais (SIA) a um problema do mundo real: como predizer fraudes e furtos de energia elétrica. Vários trabalhos tem mostrado que épossível detectar padrões de dados anormais a partir dos dados de consumidores de energia elétrica e descobrir problemas como fraude e furto

8. Identificação de regiões promotoras de Mycoplasma hyopneumoniae
Mycoplasma hyopneumoniae is one of the smallest bacteria found in nature, presenting a small genome and absence of cell wall. It is present in the majority of swine herds throughout the world, and is considered an important pathogen in the swine industry. In the last decade, many species of this genus had their genome completely sequenced, including four str

9. Sistema de reconhecimento de padrÃes para identificaÃÃo de porte de veÃculos atravÃs de anÃlise de perfil magnÃtico / A Pattern recognition system for identification of vehicles by analysis of magnetic profile
Currently, transit agencies use traffic monitoring systems to reduce traffic accidents and as a fundamental tool for collecting statistical data for planning and management of road systems. These data are observed as the amount of information vehicles that travel at a certain point, the average speed and the identification of the category of vehicles. The id

10. Um estudo sobre reconhecimento de padrões: um aprendizado supervisionado com classificador bayesiano / A study on pattern recognition: supervised learning with a Bayesian classier
The facility we have to recognize a face, to understand spoken words, reading manuscripts, identifying car keys in our pocket and deciding whether an apple is ripe by its smell, belie the complex processes that are behind the act to recognize these patterns. These recognitions have been crucial to our survival, and over the past tens of millions of years sop

12. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such
