Este artigo aborda a Rede Social Educacional do Município de Novo Hamburgo, nomeada como RedEdu. A RedEdu está em desenvolvimento desde o início do ano de 2013, sendo uma ferramenta colaborativa e de socialização para a comunidade da Rede Municipal de Ensino. A rede é baseada em conceitos amplamente difundidos entre os usuários da Internet [...]
The Kinect™ has been developed to recognize gestures and voice commands, through a set of cameras and microphones, respectively. This paper proposes and evaluates low-cost Sound Source Localization (SSL) solution based this off-the-shelf equipment. It consists of employing a pair of Kinect devices as an alternative for microphone array, and executing the Steered Response Power [...]
The present study aimed to develop and implement a method for detection and classification of spectral signatures in point clouds obtained from terrestrial laser scanner in order to identify the presence of different rocks in outcrops and to generate a digital outcrop model. To achieve this objective, a software based on cluster analysis was created, [...]
This paper presents an on-the-fly procedure for obtaining extrinsic camera parameters of onboard vehicular cameras, as well as augmented reality applications for driver assistance systems and road inspection. The proposed approach employs a lane detection algorithm to extract the lane boundaries of the road, and estimates the distance between adjacent lane markings based on the [...]
In recent years, there has been growing support for more tightly coupled applications regarding heterogeneous resources. A specific way of obtaining better performance in such applications is to consider the replacement of execution entities by newer resources during the application's lifetime. Therefore, this article describes the rationale for developing jMigBSP, which is a Java programming [...]
Nowadays, Brazil has an expected growth in the tourism sector due to the FIFA World Cup (which had a huge success) and the Olympics in Rio de Janeiro. However, there is a lack of tourism applications for Brazil, such as Electronic Tourism Guides (ETGs) for mobile devices. The existence of ETGs that takes into account [...]
Este artigo tem como objetivo apresentar as idéias para o desenvolvimento de um framework para balanceamento de carga chamado GetLB. Considerando o contexto de transferência eletrônica de fundos (TEF), GetLB oferece uma nova forma de organizar as interações entre o chaveador e as máquinas processadoras. Esta organização permite que o chaveador combine informações atualizadas para [...]
The lack of empirical knowledge about the effects of model composi-tion techniques on developers' effort is the key impairment for their widespread adoption in practice. This problem applies to both existing categories of model composition techniques, i.e. specification-based (e.g. Epsilon) and heuristic-based (e.g. IBM RSA) techniques. This paper reports on a controlled experiment that investigates [...]
Um dos problemas que as universidades brasileiras vêm enfrentando é ocrescente número da evasão escolar. Pesquisas foram realizadas sobre este assunto afim de identificar padrões que expliquem este comportamento visando contribuircomo uma forma de minimizar o impacto da evasão escolar. Este artigo apresentauma pesquisa onde se buscou, através da aplicação do processo de Descoberta deConhecimento [...]
This work presents an introduction to Information Extraction systems and a survey of the known approaches of Information Extraction in the legal area. This work analyzes with particular attention the techniques that rely on the representation of legal knowledge as a means to achieve better performance, with emphasis on those techniques including ontologies and linguistic [...]
