Abstract
Flooding is a critical global problem, which is growing more severe due to the effects of climate change. This problem is particularly acute in the state of São Paulo, Brazil, where flooding during the rainy season incurs significant financial and human costs. Another critical problem associated with flooding is the high level of pollution presen...... hiện toàn bộ
A semantic approach for QoS specification of communication services using QoE parametersSpringer Science and Business Media LLC - - 2013
José Cé Júnior, Achilles Colombo Prudêncio, Roberto Willrich, Madalena Pereira da Silva
Abstract
Various operations related to Quality of Service (QoS) management in communication networks require the clients/users to specify the quality level of the network service. The current QoS proposals adopt a fixed set of performance parameters at the network level to specify quality levels, avoiding dealing with the problem of heterogeneity among Qo...... hiện toàn bộ
Increasing sensor reliability through confidence attributionSpringer Science and Business Media LLC - Tập 25 - Trang 1-20 - 2019
Roberto M. Scheffel, Antônio A. Fröhlich
The reliability of wireless sensor networks (WSN) is getting increasing importance as this kind of networks are becoming the communication base for many cyber-physical systems (CPS). Such systems rely on sensor data correctness to make decisions; therefore, faulty data can lead such systems to take wrong actions. Errors can be originated by sensor’s hardware failures or software bugs and also from...... hiện toàn bộ
Referenceless image quality assessment by saliency, color-texture energy, and gradient boosting machinesSpringer Science and Business Media LLC - Tập 24 - Trang 1-16 - 2018

In most practical multimedia applications, processes are used to manipulate the image content. These processes include compression, transmission, or restoration techniques, which often create distortions that may be visible to human subjects. The design of algorithms that can estimate the visual similarity between a distorted image and its non-distorted version, as perceived by a human viewer, can...... hiện toàn bộ
An investigation of the predictability of the Brazilian three-modal hand-based behavioural biometric: a feature selection and feature-fusion approachSpringer Science and Business Media LLC - Tập 26 - Trang 1-20 - 2020
Julliana Caroline Goncalves de A. S. Marques, Tuany Mariah Lima Do Nascimento, Brenda Vasiljevic, Laura Emmanuella Alves dos Santos Santana, Márjory Da Costa-Abreu
New security systems, methods or techniques need to have their performance evaluated in conditions that closely resemble a real-life situation. The effectiveness with which individual identity can be predicted in different scenarios can benefit from seeking a broad base of identity evidence. Many approaches to the implementation of biometric-based identification systems are possible, and different...... hiện toàn bộ
Formal Specification and Verification of Real-Time Systems using Graph GrammarsSpringer Science and Business Media LLC - - 2007
Leonardo Michelon, Sérgio Ely Valadão Gigante de Andrade Costa, Leila Ribeiro
Abstract
The importance of real-time systems has enormously increased in the last decade. Application areas that typically need real-time models include railroad systems, intelligent vehicle highway systems, avionics, multimedia and telephony. To assure that such systems are correct, additionally to prove that they provide the required functionality, time...... hiện toàn bộ
Detecting referential inconsistencies in electronic CV datasetsSpringer Science and Business Media LLC - Tập 23 - Trang 1-11 - 2017
Ivison C. Rubim, Vanessa Braganholo
One way to measure the scientific progress of a country is to evaluate the curriculum vitae (CV) of its researchers. In Brazil, this is not different. The Lattes Platform is an information system whose primary objective is to provide a single repository to store the CV of the Brazilian researchers. This system is increasingly acquiring expressiveness as the main source of information regarding the...... hiện toàn bộ
Overview and open issues on penetration testSpringer Science and Business Media LLC - Tập 23 - Trang 1-16 - 2017
Daniel Dalalana Bertoglio, Avelino Francisco Zorzo
Several studies regarding security testing for corporate environments, networks, and systems were developed in the past years. Therefore, to understand how methodologies and tools for security testing have evolved is an important task. One of the reasons for this evolution is due to penetration test, also known as Pentest. The main objective of this work is to provide an overview on Pentest, showi...... hiện toàn bộ
