Investigations into the use of the finite element method and artificial neural networks in the non-destructive analysis of metallic tubes

This work presents an investigation into the use of the finite element method and artificial neural networks in the identification of defects in industrial plants metallic tubes, due to the aggressive actions of the fluids contained by them, and/or atmospheric agents. The methodology used in this study consists of simulating a very large number of defects in a metallic tube, using the finite element method. Both variations in width and height of the defects are considered. Then, the obtained results are used to generate a set of vectors for the training of a perceptron multilayer artificial neural network. Finally, the obtained neural network is used to classify a group of new defects, simulated by the finite element method, but that do not belong to the original dataset. The reached results demonstrate the efficiency of the proposed approach, and encourage future works on this subject.

Tridimensional modeling of the cardiac wall

The advance in the graphic computer's techniques and computer's capacity of processing made possible applications like the human anatomic structures modeling, in order to investigate diseases, surgical planning or even provide images for training of Computer Aided Diagnosis (CAD). On this context, this work exhibits an anatomical model of cardiac structures represented in a tridimensional environment. The model was represented with geometrical elements and has anatomical details, as the different tunics that compose the cardiac wall and measures that preserves the characteristics found on real structures. The validation of the anatomical model was made through quantitative comparations with real structures measures, available on specialized literature. The results obtained, evaluated by two specialists, are compatible with real anatomies, respecting the anatomical particularities. This degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the cardiac diseases on the quality of the images, as well as on the performance of the CAD. © 2010 IEEE.

Simulation-based cutaneous surgical-skill training on a chicken-skin bench model in a medical undergraduate program

Background: Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. Aims: To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model. Materials and Methods: One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation. Results: A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined. Conclusion: The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described. © Indian Journal of Dermatology 2013.

Artificial neural network model of discharge lamps in the power quality context

This paper presents a methodology for modeling high intensity discharge lamps based on artificial neural networks. The methodology provides a model which is able to represent the device operating in the frequency of distribution systems, facing events related to power quality. With the aid of a data acquisition system to monitor the laboratory experiment, and using $$\text{ MATLAB }^{\textregistered }$$ software, data was obtained for the training of two neural networks. These neural networks, working together, were able to represent with high fidelity the behavior of a discharge lamp. The excellent performance obtained by these models allowed the simulation of a group of lamps in a distribution system with shorter simulation time when compared to mathematical models. This fact justified the application of this family of loads in electric power systems. The representation of the device facing power quality disturbances also proved to be a useful tool for more complex studies in distribution systems. © 2013 Brazilian Society for Automatics - SBA.

“Criança não deveria morrer”: significados atribuídos por profissionais de saúde ao paliar crianças em iminência de morte

Este estudo tem por objetivo compreender os significados atribuídos por profissionais que atuam em enfermaria pediátrica sobre o cuidar da criança com doença sem possibilidade de cura, hospitalizada e em processo de morte. A estratégia metodológica foi fundamentada na abordagem qualitativa, que corresponde a um método preocupado com as singularidades e particularidades de um objeto, sem a pretensão de generalizações ou de verdades absolutas quanto aos resultados encontrados. A pesquisa foi desenvolvida na Clínica Assistencial Pediátrica do Hospital Universitário João de Barros Barreto, vinculado à Universidade Federal do Pará, em Belém-Pa. Colaboraram com a pesquisa doze (12) profissionais, sendo 3 Médicos, 1 Psicólogo, 1 Terapeuta Ocupacional, 2 Enfermeiros, 1 Fisioterapeuta, 1 Assistente Social e 3 Técnicos em Enfermagem que lidam diariamente com o processo de morrer de crianças internadas nesta instituição. Como instrumento para coleta dos dados foi utilizado a entrevista semi-dirigida, sendo realizada a análise de conteúdo temática, por meio da qual foram identificados três temas centrais: A Negação e Interdição da Morte; Apegos e a Experiência do Luto e Formação para Paliar. Para os colaboradores paliar é uma árdua tarefa envolvendo todo cuidado direcionado à criança sem possibilidades terapêuticas curativas. Contudo, na impossibilidade de evitar a morte da criança os profissionais podem vivenciar intenso sofrimento, o que favorece as ações obstinadas para manutenção da vida, a negação e interdição da morte. Tal como pais apegados e cuidadosos para com seus filhos, na iminência de morte ou óbito da criança, os profissionais vivenciam sentimentos característicos do luto. Em relação à formação do profissional de saúde destaca-se a ausência de disciplinas abordando o tema da morte e do morrer durante os anos da graduação, chamando atenção para a necessidade da inclusão dessas nos currículos da graduação. Os achados sugerem o estranhamento frente à morte da criança e a vivência do luto não autorizado, corroborando em favor das ações de educação para vida e para morte.

Implementação da metodologia lean manufacturing em uma linha de produção por meio de certificação interna

To the companies maintain competitive in the market, they need continuous improvement in quality and productivity. This continuous improvement can be achieved through lean manufacturing tools. The idea of lean manufacturing is to map the flow to identify the processes that don’t add value in the final product, according the customer specification, in others words is eliminate or reduce the waste on the production flow. However the implementation of lean manufacturing is not so simple and involves the resistance of the employees, lack of training and the lack of knowledge to make the implementation. The objective of this study is determinate the good practices and difficulties found by a multinational company in the field of healthy that aims implementing the Lean Manufaturing through an internal certification. The methodology used to approach the problem is a case of study that analyzes the information introduced through discussion made by a semi structured interview. The case study describes the steps to get the certification, involving the concepts of 5S, balancing, standardization and routine management. The literature and the study case showed that the good practices, such as productivity increases, safety level increases and the machine stability were accomplished, but the majority difficulties was found in cultural factors and planning. Some recommendations were proposed to the others companies, such as the elaboration of a qualification matrix and the review of the activities chronogram during the implementation. The way that the company found to implement Lean Manufacturing concepts was a creative method to show to everybody the objective and the target to be accomplished and is one way to recognize the effort through the certification
