Programa de educação tutorial PET - Engenharias Conexões de saberes: uma experiência com o ensino remoto emergencial
(Universidade Federal de Goiás, 2022-06-15) Soares, Giovanna Luiza; Xavier, João Vitor Menengon; Nascimento, Andreia Aoyagui
The year of 2020 was marked by the COVID-19 pandemic. Many of the common practices in force by then gained a new acting locus. Within education, the classroom activities were replaced by online and distance education at most institutions. In this context, the PET-Engineering Knowledge Connections group, from the Federal University of Goiás (UFG), proposed to conduct two different courses: basic Python programming language and computer-aided design, both using the Digital Information and Communication Technologies (TDICs) provided by UFG. Our findings confirm the positive influence of sharing experiences and the implications of this study are considered under the three categories of academic, managerial, and technological perspectives. This can include supporting the introduction of new concepts as part of learning about science and technology, and introducing more general engineering knowledge, through more constructive (and collaborative) support
Estimação de envelope efetivo de tráfego de redes baseada em modelagem multifractal para controle de admissão de usuários com qualidade de serviço
(2013) Vieira, Flávio Henrique Teles; Lucas, Rosana de Paula; Vieira, Renata Teles
In this paper, first we present an effective bandwidth equation for multifractal traffic based on a multiplicative cascade model. Merging the effective bandwidth to the effective envelope concept from the Statistical Network Calculus, we compute end-to-end performance bounds for real multifractal network traffic. Using these bounds, we propose an admission control scheme that guarantees quality service in terms of data loss probability and delay through the obtained effective envelope for the MWM (Multifractal Wavelet Model) multifractal model. Through simulations, we compare the number of flows admitted using effective service curves corresponding to different types of traffic flow schedulers for the fBm (fractional Brownian motion) andMWM traffic models.
Traffic modeling in PLC networks using a Markov fluid model with autocorrelation function fitting
(2011) Rocha, Flávio Geraldo Coelho; Santos, Christiane Borges; Vieira, Flávio Henrique Teles
In this paper, we present an analysis of VoIP (Voice over IP) traffic and data transfer using PLC (PowerLine Communications) network. We propose a model based on MMFM (Markov Modulated Fluid Models) for data and VoIP traffic in PLC networks. Simulations and comparisons were carried out to verify the efficiency of the proposed traffic model over the Poisson and MMPP (Markov Modulated Poisson Process) models.
Modelagem de tráfego VoIP utilizando misturas gaussianas ajustadas por algoritmo de maximização de esperança e comprimento de descrição mínimo
(2013) Oliveira, Cheila Mendes de; Lucas, Rosana de Paula; Vieira, Flávio Henrique Teles
The increase in the number of applications that generate VoIP (Voiceover IP) traffic requires that suitable models for this kind of traffic be used to bet-ter dimension and predict network resources. In this paper,we propose the applica-tion of Gaussian mixture adjusted by an EM algorithm (Expectation-Maximization)with selection of classes using the principle of Minimum Description Length (MDL-Minimum Description Length) in order to describe VoIP traffic. Real VoIP traces werecollected and synthetic time series were generated according to these data. The propo-sed algorithm is compared to the EM algorithm and the MDL (Minimum DescriptionLength) based algorithm in terms of performance in modelingthe considered VoIPtraffic traces.
Programa de educação tutorial na Escola de Engenharia Elétrica, Mecânica e de Computação (EMC) da UFG: as dimensões do trabalho e da formação
(Getúlio Antero de Deus Júnior, 2014-12) Deus Júnior, Getúlio Antero de; Chaveiro, Eguimar Felício
This paper investigates how the Programa de Educação Tutorial (PET/CAPES, Tutorial Training Program) relates to both professional training and the job market, based on activities developed by the PET – Engenharias (Conexões de Saberes) group, at the Escola de Engenharia Elétrica, Mecânica e de Computação (EMC), Universidade Federal de Goiás (UFG). Two issues are considered: how may PET activities be transformed, to provide the PET participant with a favourable environment and conditions for a successful career, and likewise for concluding undergraduate studies and going on to graduate school. In that context, a reflection upon both the programs underlying philosophy and the relationship between professional and academic life, is presented. The conclusions of that reflection are discussed together with the results of a survey, specifically developed to collect the experiences within the PET program, from ex and current participants.
Environmental education and energy efficiency as strategies for reducing energy consumption in public school building in Goiânia
(Getúlio Antero de Deus Júnior, 2019-12) Rosa, Marlison Noronha; Sousa, Yan Machado; Hora, Karla Emmanuela Ribeiro; Kopp, Katia; Deus Junior, Getúlio Antero de; Rosales, Camilo
Electrical energy is essential for the quality of life of people, who use it in di erent socioeco- nomic activities and for technological development. In view of the gradual increase in the demand for electricity and the future possibility of not serving all the consumer sectors, it is necessary to optimize it. The objective of this study was the application of strategies based on the pillars of energy e ciency and environmental education in order to minimize the expenditure of electric energy in public buildings, which were selected for this project due to the fact that, its users show a lack of concern about the correct consumption of electric energy since the expenses are tied to the public co ers and are not always perceived by the people as resources coming from the taxes paid by the citizens. Among the public buildings that consume the most electric energy, the most important are those in the Education Sector. In fact, a larger project called the Energy E ciency Project in Public Buildings in Goi ania (PEEEPG), to which this work is linked, found that among the municipal public buildings, the education sector is responsible for approximately 30% of the electricity consumption and, therefore, this speci c sector was selected for the application of the selected strategies. The methodology used was based on research-participant, environmental edu- cation together with replacement of lamps by LED system (Light Emitting Diode) at strategic locations in the building and monitoring of results. The actions carried out included the lamp re- placement, and educational lectures o ered to students of di erent age groups in three school shifts with a partnership of employees and teachers of the municipal school selected on energy e ciency and strategies to reduce the consumption of electricity. The project mobilized directly about 200 people belonging to the target audience and indirectly 800 students who were part of the teaching unit. It was collected a data base among 2012 to 2016. The methods of data collection and analysis were based on documentary research, analyzing the electric energy bills of the building, as well as documents and legislation of the municipality itself on the consumption of electric power and the architecture model applied to school environments in Goi ania. The results obtained, after a monito- ring period of six months (November to April) during the years 2016 and 2017, indicated an analyze to reduction of 16% of the consumption of electric energy in the building, compared to the same period in the previous year. Therefore, this result regard to the possibility of investments in energy e ciency projects for public buildings, subsidizing actions in the design, retro t and maintenance of public buildings.
Clown group - engineers without borders (knowledge connections): building a humanistic training in engineering courses
(Getúlio Antero de Deus Júnior, 2018-12) Alves, Ricardo Henrique Fonseca; Deus Júnior, Getúlio Antero de; Kunzler, Jonas Augusto; Silva Filho, Antônio Marcelino da
The Clown Group Engineers without Borders (Knowledge Connections) is a group of clowns formed by Engineers and Engineering students. The theoretical basis of the Clown Group goes back to the origins of Jerzy Grotowski's poor theater (1933 1999). Concerning the use of music, theater and dance to present and promote the pleasure of art, the Group values the interaction with the public and does not worry about the structural elements commonly characterized by the theater as stage and lighting. In this way, the Clown Group promotes a Humanistic Formation of its members by providing a development in the capacity of communication, contact with the external community and also the satisfaction, by allowing the art to be spread in a simple and e ective way. The objective of this work is to analyze the importance of Humanistic Training in the professional and personal development of Engineers and Engineering students, treating as a special case the Humanistic Training linked to the actions of the Clown Group Engineers without Bor- ders (Knowledge Connections). As a hypothesis, it is expected that the experience of members and ex members of the Clown Group can be proven through their training and presentations over the years. In order to evaluate the personal and professional development of members and ex members of the Clown Group during the training process, a qualitative research was carried out, via an applied questionnaire, in addition to a documentary research by observation, in which data were collected through analysis and observation of photos and documents of the Clown Group. In ad- dition, Arti cial Neural Networks were used to correlate the members and ex members based on the two applied researches. The members and ex members of the Clown Group have experienced a major break in introspection, signi cantly improving their way of communicating with society. The members and ex members presented an improvement in the way they relate to each other in a team, a fundamental aspect of an Engineer's professional life. The Clown Group presents itself as a very important action for Humanistic Training and the professional and personal development of Engineers and Engineering students. The di usion of art in the academic and external community promoted by the Clown Group also allows the deconstruction of the stereotype that the areas of Engineering and the Arts cannot coexist.

Grupo Clown - engenheiros sem fronteiras (conexões de saberes): construindo uma formação humanística nos cursos de engenharia por meio da arte, cultura e conexões de saberes
(Getúlio Antero de Deus Júnior, 2015-12) Gomes, Analice Silva; Silva Filho, Antônio Marcelino da; Andrade, Bruno Henrique Castro de; Silva, Carlos Leandro Borges da; Silva Júnior, Cleidson César da; Lopes Filho, Gilberto; Leitão, João Luiz Andrade; Kunzler, Jonas Augusto; Dias, Laura Vitória Rezende; Paula, Marcelo Vinícius de; Santos, Maria Luisa Matias dos; Cherubin, Ricardo; Melo, Thaís Borges de; Deus Júnior, Getúlio Antero de
The Grupo Clown - Engenheiros Sem Fronteiras (Conex~oes de Saberes) is a group of clowns made up of Engineers and students of Engineering courses. Cultural performances are held in conventional and unconventional spaces without worrying about the setting. However, there are concerns regarding the costumes of clowns and the use of musical instruments. The theoretical basis of clown groups dates back to the origins of Poor Theatre, Jerzy Grotowski (1933-1999). To integrate the use of music, theater and dance to present and promote the enjoyment of art, the clown group values the interaction with the audience without assigning great importance to conventional elements of theater, such as backdrop, stage and lighting. In this way, the clown group rewards its members by providing development of their communication skills, contact with the community surrounding the Universidade Federal de Goi as (UFG) and also the satisfaction of disseminating art in a simple and effective way. Therefore, the clown group promotes a humanistic education while contributing to the improvement of communication skills of its members. In the ve years of the group's creation, fourteen presentations were performed, including a show with a nation-wide audience.
