Authors: Pereira Fábio Dacêncio , Penteado Cesar Giacomini
Published: February 2018

A Integridade da Informação é uma das metas relacionadas à segurança de informações que se destaca no cenário atual com o advento da Internet. Uma das técnicas e métodos para garantir a integridade de uma informação é a utilização de funções de hash, que gera uma cadeia de bytes (hash) que deve ser única para identificar um conteúdo digital. Porém grande parte das funções atuais já não consegue evitar ataques maliciosos e garantir que a informação tenha apenas um hash. Por meio de uma chamada pública o National Institute of Standards and Technology (NIST) convocou centros tecnológicos, empresas e a comunidade científica para enviar propostas para o novo padrão de função de hash, chamado de SHA-3. Uma vez apresentados os candidatos, estes são expostos e avaliados em diversos aspectos. Neste processo, o algoritmo Keccak foi vencedor da chamada em 2012. Neste trabalho apresenta-se o algoritmo SHA-3 implementado em smart cards, com o intuito de obter de dados de desempenho para futura comparação com trabalhos correlatos.

Authors: Mano Leandro Yukio , Sawada Luana Okino , Ueyama Jó
Published: February 2018

Current studies in the field of Human-Computer Interaction highlight the relevance of emotional aspects while interacting with computers systems. It is believed that by allowing intelligent agents to identify user’s emotions it becomes possible to induce and arouse emotions itself in order to stimulate the users in their activities. One of the great challenges for researchers is to provide systems capable of recognizing, interpreting and reacting intelligently and sensitively to the emotions of the user. In this sense, we propose an affective interaction between the music player and the user that is based on emotional recognition through the interpretation of facial expressions. Therefore, this project aims to develop and evaluate a system that can identify the user’s emotional state and provide a persuasive mechanism to change it (with a case study in music player). Also, explore the flexible approach in persuasion through persuasive mechanisms that may vary between a music player, games and / or videos. Thus, throughout the study, the model based on the Classification Committee was efficient in identifying the basic emotions and the satisfaction of the users through the application with the music player.
Detecção Automática de Incompatibilidades Cross-Browser utilizando Redes Neurais Artificiais
Authors: Paes Fagner Christian , Watanabe Willian Massami
Published: February 2018

Cross-Browser Incompatibilities (XBIs) represent inconsistencies in Web Application when introduced in different browsers. The growing number of implementation of browsers (Internet Explorer, Microsoft Edge, Mozilla Firefox, Google Chrome) and the constant evolution of the specifications of Web technologies provided differences in the way that the browsers behave and render the web pages. The web applications must behave consistently among browsers. Therefore, the web developers should overcome the differences that happen during the rendering in different environments by detecting and avoiding XBIs during the development process. Many web developers depend on manual inspection of web pages in several environments to detect the XBIs, independently of the cost and time that the manual tests represent to the process of development. The tools for the automatic detection of the XBIs accelerate the inspection process in the web pages, but the current tools have little precision, and their evaluations report a large percentage of false positives. This search aims to evaluate the use of Artificial Neural Networks for reducing the numbers of false positives in the automatic detection of the XBIs through the CSS (Cascading Style Sheets) and the relative comparison of the element in the web page.

Published: February 2018

For several years, cloud computing systems have been generating debate and interest within IT corporations. These cloud computing environments provide storage and processing systems that are adaptable, efficient and simple, thus allowing for rapid infrastructure modifications to be made, according to constantly changing workloads. Organizations of any size and type are migrating to the cloud supporting solutions based on Web. Due to the benefits of the pay-per-use model and scalability factors, services such as Video Streaming. Recent failure events in Video Streaming services have demonstrated the critical importance of maintaining high availability in cloud computing infrastructures. One of the methods used to identify the trends of occurrences of failures in computational systems, occurs through the application of strategies of sensitivity analysis. This paper uses hierarchical modeling and different sensitivity analysis techniques to determine the parameters that cause the greatest impact on the availability of a Video on Demand.  The results show that distinct approaches provide similar results regarding the sensitivity ranking, with specific exceptions. A combined evaluation indicates that system availability may be improved effectively by focusing on a reduced set of factors that produce large variation on the measure of interest.

Published: February 2018

The hospital area is constantly in need of care and attention. Because of its urgencies, it has vulnerabilities and risks that hinder the quality of hospital management. Technological management tools are effective in improving processes and strategic administration because they provide information reliability. The aim of this work is to propose to the Brazilian’s Federal University Hospitals (BFUHs) and to the Brazilian Hospital Services Company (BHSC) the use of an open source Business Intelligence (BI) tool, Pentaho, to analyze the efficiency of Hospital Indicators (HIs) and to support the clinical decision-making. This paper describes BI and Pentaho, as well as the main points of the efficiency documentations established by the National Agency of Supplementary Health (NASH), with emphasis on the HIs: Hospital Occupancy Rates (HORs) and Averages Length of Stay (ALSs). The Pentaho does the data extraction and the transformation, as well as loading them into the Data Warehouse (DW), all based on a relational database from BHSC. After that, dimensional cubes are created for the generation of graphic panels in dashboards. Most BHSC hospitals are not yet adequately using their operational beds and neither managing correctly the average length of hospitals patients stay, being outside the goals established by NASH. Several steps are taken to achieve efficient hospital administration. However, the joint working of Information and Communication Technologies (ICTs) solutions with the health area and its standards provides a major step towards efficient hospital management.

Corrosion behavior of 3 wt.-% Chromium (3Cr) tubing steel in CO2 saturated high-salinity brine was investigated by using an autoclave in the laboratory. The partial pressure of CO2 and the Cl− concentration were fixed at 0.2 MPa and 139552 mg × l−1, respectively. The water cut was varied from 20 to 100 vol.-%, and the temperature was varied from 50 to 110 °C. For comparison, the corrosion behaviors of N80 carbon steel and 13 wt.-% Cr (13Cr) martensitic stainless steel were tested in the same conditions. The surface morphologies and chemical composition of corrosion product layers were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectrometry (EDS) technologies. The results show that the 3Cr steel's corrosion rate increased as water cut increased, especially when the water cut exceeded 70 vol.-%. Serious general corrosion and local attack occurred on the 3Cr samples in a 0.2 MPa CO2 and 139552 mg × l−1 Cl− corrosion environment. The product layer structure of 3Cr steel in high-salinity brine is demonstrated. When the chloride ion concentration is high enough, the Cr-enriched layer no longer provides sufficient protection against the chloride ion penetration and pitting attacks may occur.

The pulverized coal flow in the two-phase gas-solid is monitored based on the ECAH (Epstein, Carhart, Allegra, Hawley) theoretical model. The relationship between the volumetric concentration of the pulverized coal and the ultrasound attenuation coefficient is analyzed. The flow velocity and concentration of the coal particles is measured using two ultrasonic probes at an angle of 45° to the flow direction. The results show that the aberration of the ultrasonic on-line measurements of the pulverized coal flow is less than 3 % compared to the coal flow set by the experimental boiler test platform. The general feasibility and reliability of the ultrasonic method of the flow measurements is verified.

The product design process has a very important effect on product costs. It aims to develop products that are able to compete by achieving an optimum design in the product design process. This research presents the first application in the literature of the grey wolf, whale, water cycle, ant lion and sine-cosine optimization algorithms for the optimum design of vehicle components. In this study, the optimal structural model of a vehicle connecting rod was determined. In the optimization process, various design alternatives were created by using the latin hypercube method. Stress analysis was performed for each of these designs. According to the generated responses, equations for objective and constraint functions were obtained. The optimization problem was solved using the above mentioned algorithms which have been newly developed in the literature, resulting in optimum connection rod design. The results demonstrate that the grey wolf, whale, water cycle, ant lion and sine-cosine algorithms are very important options in optimizing design and manufacturing optimization problems.
Formation of zirconia precursor nanoplates mediated by ionic liquid and transformation to monoclinic ZrO2 nanostructures
Authors: Tian Pei , Lin Hechun
Published: February 2018

The [Zr(OH)5]− imidazolium complex was used to synthesize a zirconia precursor with plate-like nanostructue hydrolyzed under strong acid conditions, which was characterized by means of powder X-ray diffraction, thermogravimetric-differential scanning calorimetry, Fourier transform infrared spectroscopy, Raman spectroscopy, elemental analysis, inductively coupled plasma and electronic differential system. The zirconia precursor can be transformed to monoclinic ZrO2 by annealing at a temperature above 400 °C. With the increasing of the curing temperature, it tended to give rise to porous ZrO2 nanostructures.
Effect of processing parameters on the grain refinement of vanadium nitrogen microalloyed steel
Authors: Zhao Baochun , Zhao Tan , Li Guiyan
Published: February 2018

The effect of processing parameters on the grain refinement of vanadium nitrogen microalloyed steel was investigated by performing hot deformation tests. The interaction between static recrystallization and precipitation was analyzed and the effect of final temperature, cooling rate and holding time on the microstructure of the tested steel is discussed. The results showed that smaller ferrite grains could be obtained with lower temperature or higher cooling rate. It was found that carbonitrides could precipitate at temperatures around 850 °C, which could retard recrystallization. The precipitated particles could inhibit grain growth and promote ferrite nucleation, which leads to ferrite grain refinement. Therefore, fine ferrite grains could be obtained by performing multi-pass compression testing at this specific finishing temperature followed by appropriate holding.
Opinions des étudiants du diplôme d'études spécialisées complémentaires de médecine d'urgence au sujet du nouveau diplôme d'études spécialisées de médecine d'urgence
Authors: Neraal S. , Freund Y.
Published: February 2018

Introduction : La reconnaissance de la médecine d'urgence en France en tant que spécialité de plein exercice se concrétise par la mise en place de son diplôme d'études spécialisées (DES). Cette formation remplacera et rendra inaccessibles le diplôme d'études spécialisées complémentaires (DESC) de médecine d'urgence et capacité de médecine d'urgence ainsi que tous les autres DESC, et permettra la qualification ordinale comme urgentiste. Nous avons voulu connaître le ressenti des étudiants de l'actuel DESC de médecine d'urgence vis-à-vis de cette évolution.

Méthode : Nous avons interrogé les étudiants en cours de DESC de médecine d'urgence d'Île-de-France en mars 2017. Le critère de jugement principal était la proportion de ces derniers qui auraient fait le choix du DES de médecine d'urgence dès l'examen classant national (ECN) s'ils en avaient eu la possibilité. Secondairement, ils étaient interrogés sur leur souhait de s'inscrire à l'Ordre des médecins comme urgentistes et sur leur accord pour poursuivre le DESC dans l'hypothèse où celui-ci deviendrait qualifiant.

Résultats : Sur 253 étudiants interrogés, 95 réponses ont été reçues. Quarante-et-un pour cent affirment qu'ils auraient choisi le DES de médecine d'urgence dès l'ECN s'il avait été disponible. Trente-huit pour cent souhaitent s'inscrire à l'Ordre des médecins comme urgentistes. Si le DESC de médecine d'urgence devenait qualifiant, 39 % accepteraient de poursuivre cette formation. Le souhait de choisir le DES de médecine d'urgence s'il avait été disponible à l'ECN est fortement associé au souhait de poursuite du DESC s'il devenait qualifiant et à celui de s'inscrire à l'Ordre comme urgentiste.

Discussion : Ces résultats suggèrent que près de trois étudiants sur cinq actuellement en DESC n'auraient pas choisi le DES de médecine d'urgence. Les futurs étudiants du DES de médecine d'urgence auraient ainsi un profil différent des actuels DESC.

Compost tea, Tilt 250 EC and Bavistin 50 WP were evaluated for controlling brown spot and narrow brown spot diseases of rice in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh during the period from July to December, 2011. Significant effect of different treatments was observed on the severity of brown spot and narrow brown spot of rice as compared to control. The results evidently showed the lowest brown spot severity in T4 (Tilt 250 EC applied as foliar spray) which was statistically similar to T3 (Compost tea as soil drenching) while the highest severity was recorded in untreated control plot at booting and ripening stage. But narrow brown spot severity was lowest in T4 (Tilt 250 EC as foliar spray) which was similar to T5 (Tilt 250 EC as soil drenching), T6 (Bavistin 50 WP as foliar spray) and highest severity was found in T2 (Compost tea as foliar spray) which was statistically similar to T1 (control), T3 (Compost tea as soil drenching), T7 (Bavistin 50 WP as soil drenching) at booting stage. But at ripening stage the highest severity was found in T1 (control) and the lowest severity was found in T4 (Tilt 250 EC as foliar spray) which was statistically similar to T5 (Tilt 250 EC as soil drenching). However, soil drenching and foliar application of compost tea performed better as compared to control in reducing the severity of brown spot. But compost tea as foliar spray increased the narrow brown spot disease. Significant effect of the treatments was observed on growth and yield contributing characters except panicle length. Foliar and soil application of Tilt and soil application of compost tea showed better performance in increasing growth and yield contributing characters as compared to all other treatments.Bangladesh J.
