This paper proposes FingerCodes as a touchless fingerprint matcher and compares it with the traditional minutia- based approach. First, the input images are processed with a touchless-to-touch algorithm in order to generate touchbased equivalents used in the minutia-based matching evaluation. Ragarding FingerCodes, each touchbased equivalent is used...

Edge Computing (EC) is a technological paradigm that emerged with the aim of fulfill the need of applications for low latency. Despite the advances in data sharing and processing among remote entities using cloud and mobile computing, low latency and availability requirements led to the distribution of processing power to the edge of the network,...

O Syn-flooding é um ataque de negação de serviço (DoS) simples de ser realizado, porém tem consequências desastrosas, podendo impossibilitar o acesso a um site ou outros recursos em uma rede. Em Redes Definidas por Software (SDN), ele pode parar uma rede por completo, a partir da negação do serviço do próprio controlador. Este trabalho propõe...

The irradiation diagram is one of the most important characteristics of an antenna, whether miniaturized, compact or large (parabolic). In addition to gain and polarization, the measurement of the irradiation diagram is performed for each plane individually and often manually. Therefore, a measurement system is necessary to perform tests on any...

This paper presents VALIDA, a low cost tool for agile commissioning of virtual circuits to access networks infrastructures. VALIDA has low cost of deploy and operation, and is able to homologate simultaneously the real capacity of multiples link using a API REST to facilitate the troubleshooting in networks performance bottlenecks. VALIDA is in...

Cellular systems are becoming more important to the society, and this demands more capacity and new features. A new generation of systems, with better characteristics, and the use of advanced technologies are under development: the 5G networks. Smart Cities are evolving and will benefit from this new cellular generation. Several organizations are...

O objetivo deste artigo é estudar o problema de filtragem adaptativa e apresentar solução para reduzir a interferência intersimbólica (IIS) na equalização de sinais, no contexto de redes de sensores sem fio, operando no modo difusão. Para isso, estendemos o critério de equalização cega Setmembership do Módulo Constante (SM-CM) [1] para o contexto de...

A Genetic Algorithm (GA) is proposed for Initial Access (IA) beamforming schemes based on codebook, considering a system with a large number of transmit antennas in the base statio and a single-antenna user, operating on the millimiter wave band. The efficiency of the proposed GA is investigated and comparisons are realized. Additionally, the effect...

The pileup phenomenon is related to the rate of occurrence of the events and the response time of the sensors. In the field of particle detectors, the current ATLAS hadronic calorimeter instrumentation system, one of the LHC detectors, is not effective in the reconstruction of the signals affected by the pileup. This work proposes the implementation...

Este artigo foca na análise de viabilidade do uso de identificação por radiofrequência (RFID) no rastreamento dos equipamentos de proteção individual (EPIs) de um operador de manutenção do setor de transmissão de energia elétrica. Para alcançar esse propósito, várias atividades de pesquisa e desenvolvimento foram realizas, buscando compor um cenário...
