Published: July 2021

: The placenta is a chorioallantoic, deciduate, haemochorial and villous organ. It is a vital organ which transfers vital nutrients from the mother to the foetus and removes waste products from the foetus to the mother. There has been paucity of literature regarding the morphometric study of human placenta and its vascular pattern (magisterial or dispersed) by corrosion cast technique. Therefore, the present study was conducted on morphometry and vascular pattern of the human placentae.

: To do the morphological and morphometric study of placenta and to study the vascular pattern of placenta by corrosion cast technique.

Study was done on 43 placentae and its morphometric study and vascular pattern were studied by corrosion cast technique.

: Oval was the most common shape of placenta observed in the present study. Out of 43 placentae, 22(51.16%) had oval, 16(37.20%) placentae had round shape followed by triangular in 3(6.97%) placentae. Only 1 (2.32%) placenta each found to be irregular and multilobed. Most common shape recorded in complicated pregnancy was oval followed by round. Magisterial pattern was found in 13.95% of placenta and was associated with oval shape constituting 25.58% of placentae. Mixed pattern was seen in 18.60% placentae and was associated with oval placentae(23.25%). The disperse pattern was seen in 4.65% and was associated with oval and irregular placentae each constituting(2.32%).

: The vascular cast preparation of placentae in our study will further help in contribution towards the understanding of the placental vasculature. An effort should be made for performing more studies on placentae of complicated pregnancies eg: hypertension and diabetes etc.

Published: July 2021

From last few decades there are many changes are taking place in the field of medical education moving from traditional method to more towards online/ e-learning method using internet. The advent of electronic devices like mobile, i- pad, laptops and explosion of social media technology provides opportunities for learners to create their own personalised learning experience.

To asses the effectiveness of online learning in Anatomy among first MBBS students during COVID-19.

A Cross sectional study was conducted among 120 MBBS First year medical students for a period of 6 months (May 2020 to November 2020) at Chamarajanagara Institute of Medical Sciences, Chamarajanagara. Informed consent was obtained from all the students prior to the start of the study. The online classes were conducted due to covid-19 lockdown in our institution from May 2020 as per the guidelines from RGUHS.

In the study majority of students had concentration time of 30 min (71.7%), majority of them opined that there as moderate disturbance during online class (53.3%), majority of them opined that they had moderate internet or network issues (53.3%), majority of them used mobile phone for online class (70%). In the study overall effectiveness of online teaching in anatomy among 1 year students was 61.7% and 38.3% opined that it was not effective.

The study concludes that online classes were not so effective as students encountered lot of technical problems, reduced attention span, low motivation and lesser understanding in the concepts of subject thought.

Authors: Harsha B R  , Chandragirish S  , Mahesh V  , Shashank K J
Published: July 2021

The humerus can be broken down into four segments.  If the humerus is found in its entirety, then its length can be used to estimate stature.  However, if only segments of the humerus are recovered then a combination of segments can be used to estimate stature.

To estimate the stature using Humerus length among adult population in South India.

A Cross sectional study was carried out using purposive sampling among Medical Students at CIMS, Chamarajanagar. Study duration was 6 months from July 2019 to December 2020. 100 Male and 100 Female Medicos were included in the study after taking informed consent. Differently abled adults were excluded from the study to reduce the error. Structured questionnaire was used to collect the data such as age, gender, height, arm length or Humerus length and distance between medical and lateral condyle.

In the study among males there was significant positive correlation between Humerus length and height and distance between medial & lateral epicondyle among females there was negative correlation between Humerus length and age Among Males equation for estimation of height using Humerus length = 103.1 + 1.903 x Arm length. Among Females equation for estimation of height using Humerus length = 108.34 + 1.608 x Arm length.

As a result, these measurements may help to indicate the characteristic morphological features of humeral segments in south Indian population and also help the orthopedic surgeon to place the various implants in the reconstruction of humeral fractures.
An unusual variation in the termination of facial artery in south Indian population: A human cadaveric case report
Authors: Daniel Priyanka , Prabhu Aniketh , Samuel David Varghese , Balakrishnan Vimal
Published: July 2021

The facial artery is an important artery of the face, prone to many variations. Identification of these variations is of utmost importance in clinical practice, especially rhinoplastic and orofacial surgeries and also super selective chemotherapy procedures. In this case report, we report a bilateral facial artery variation encountered in a male cadaver during routine dissection. Instead of terminating as the angular artery, the facial artery terminated as the superior labial artery, giving the lateral nasal artery as a smaller branch, much closer to the midline than normal. A prominent pre-masseteric branch was noticed along with smaller branches from the infraorbital artery which offered possible compensation for the short facial artery. The case reported is a type II variation according to Bayram classification, and a type C variation as per Loukas classification. This variation is very rare and should be kept in mind while performing any surgical procedures of the face.

For households, water supply, power supply, pipeline gas and centralized heating are necessaries to maintain the normal life of a family. For Chinese urban families, water, electricity, gas, warm services are often provided by different government utility companies. Aimed at the shortage of the manual measurement of the above mentioned services‘ consumptions, a new mechanism using network metering devices is proposed in this paper. Based on the general network measurement mechanism and through analysis, this paper proposes using meter communication network as the public communication network of various metering devices, forming wireless mesh network by metering devices, constituting a virtual private network by the power company's network, and accessing to metering network based on SCEP protocol and certificates of devices. Under this new network measurement mechanism, a network routing optimization strategy, a data acquisition protocol based on IPv6 and a mesh network management system are designed, and preliminary experiments have been carried on. Experimental results show that the proposed mechanism can realize functions through the network, including the control of multi-measuring devices, topology discovery, data acquisition, fulfilling the multi-meter data acquisition system via network.

An overview of the energy scenario and energy storage device
Authors: Nath Bhadra Amar , Podder Subhendu
Published: July 2021

With demand for the natural resources exceeds a certain threshold, it leads to a global ecological threat like the "Amphhan” catastrophe that had ravaged the eastern part of West Bengal during the month of February 2020 that resulted in the loss of lives and economic activity which is yet to be regained with its earlier momentum. The inflicted calamity has given a "blow” as well as "boost” to renewable energy sector that leads to greater seriousness on development of the energy storages devices/stations in the country. While India has already achieved 374 GW of total installed capacity of power generation in which the contribution from the thermal sector is about 62 per cent and that of the RP is about 22 per cent that comes to 90 GW as of today and 60 GW is under pipeline or under construction or under tendering process. The year 2020 is undoubtedly a year of change and the COVID-19 pandemic situation together with enforced lockdown in several parts of the country and even in globe has forced people to think differently to remain relevant against the New-Normal. In order to choose the sources of energy that does not cause pollution to the surrounding environment, the RET is the best and most favourable options to opt for along with the battery storage devices for making the power available throughout the day-long and even when the sun sets. Most of the batteries currently produced and used in our country is lithium-ion based and is mostly imported. To be on the self-reliant mode and moving towards "Atmanirbhar Bharat” through "Make in India” we need to have more and more indigenous manufacturer of Li-ion batteries. Good news is that 10 Indian companies have already procured manufacturing technology from DRDO and large scale production of indigenous Li-ion batteries is expected soon. The National Energy Mission of the Government of India has just rolled out with a focus on the Make in India and is envisioned to take all necessary formalities and policy decisions to be adopted to incentivise advanced energy storage manufacturing in India through the application of innovation and new technology options that are available. As a science communicator, the authors strongly opine that with the appropriate support from the Government of India through the policy decisions by the Niti Aayog, India will be one of the top markets for the energy storage adoptions and manufacturing and is another way forward to mitigate the climate change by producing electricity free from carbon dioxide emissions into atmosphere and provide green energy for sustainable path of development. As we see that the energy storage is a new thrust area along with introduction of FGD technology retrofitting with the thermal power plant, we look forward to the new ecosystem to be achieved by 2030.

Authors: Tang Jingfan , . WeiFei , Zhang Min , Jiang Ming , Wang Qicheng
Published: July 2021

Aimed at the characteristic of the Software Defined Network (SDN), several green routing algorithms are proposed. However, there are many drawbacks consisted in the existing algorithms. Therefore, we propose a self-adaptive energy saving routing algorithm (LAR) which is based on residual bandwidth of links and SDN. The proposed algorithm makes the link utilization which is changing in real time as the link cost. It would obtain the topology information and link status to optimize and prune the topology for reducing the computing time of routing algorithm before selecting routing path. After a period of time, the incoming flows will automatically be gathered in heavily-loaded links. The links without traffic will be switched off while the whole network connectivity and QoS are guaranteed. Simulation results show that it is possible to reduce considerable energy consumption during off-peak hours and link energy saving can be up to 55%. And, the algorithm has the distinct advantage in terms of complexity and network performance comparing with related schemes.

Analysis on water migration in freeze-thaw process of composite lining canal in seasonal frozen soil area
Authors: Haibo Jiang , Jin Jin , Zhipeng Qin
Published: July 2021

In order to quantify the migration rule of water in composite lining canal foundation soil during the freeze-thaw process, the outdoor prototype test is performed to prove the change rules of water in different positions and depths of the rigidflexible mixed composite lining canal foundation during the whole freeze-thaw cycle. The prototype observation test shows that during the freezing period, the water content within the 0~80cm depth of the canal foundation soil increases with the depth, and that within the depth of 80~160cm decreases gradually with the depth. In the freezing period, water accumulates in the depth of 60 ~ 80cm, with a maximum water transfer amount of +13.2%, which occurs at the canal bottom. In the thawing period, the maximum water content also occurs at the canal bottom, with a maximum water transfer amount of -11.0%. Through the laboratory test of soil samples, the water migration development and change rules of the canal foundation soil, under different moisture contents and temperature gradients are studied in unilateral pattern. In the case of the same top plate control temperature, soil samples with similar initial water contents have similar water transfer amounts. The samples with higher initial water content have higher water transfer amount, with higher water accumulation, normally accumulating in the depth of 16~18cm. The results indicate that high water contents make it easy to gather water in soil samples during the freezing period.

Published: July 2021

A domestic purpose micro wind turbine realised using bamboo blade is tested for the power generation at an interval of two years and compared the performance. A CFD analysis of turbine with five blade system is carried out for an average wind velocity of 2.5m/s and structural integrity of the bamboo blade unit based on the pressure distribution is assessed. For the input wind velocity, a stream lined out flow of 5.9 m/s is found when wind turbine rotates at 300 rpm and corresponding pressure distribution is found to be maximum at the expected location of blade tip as 129 Pa. The static analysis shows a good margin. For 2.5 m/s, the wind turbine generates an average value of 3.8V with 0.25A (based on 15ï—/10W load). The wind turbine has produced nearly the same power even after a period of two years.
Classification of small scale landforms, its significance: a case study of the middle Ichamati river, India
Authors: Mondal Madhab
Published: July 2021

Landforms are the core concept of geomorphology. The definition of landforms, their characterization and classification are the core subject of geomorphology. But all these become complex when it seems to difficult to identify the landforms, especially when the area is plain land and highly modified by human activities. This paper has examined the characters of the landforms of the middle basin of the Ichamati river, the important distributary in the district of North 24 Parganas, India. It has been primarily taken an attempt to classify the landforms with the help of the satellite image, IRS P6 LISS II and LISS III. The DEM is not enough to identify the micro scale landform. To overcome this difficulty a series of field works have been conducted (2002, 2004, 2012 and 2015). The landforms have been classified according to second order derivative (Wood, 1996) method. Then ANOVA test has been applied to justify the classification. The F-statistics have indicated the effort is satisfying. The changing character of different landforms denote the river is going to be deteriorating from downstream to upward.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was transported from China to Iran via passengers. The virus is transmitted through droplets from coughing, sneezing, talking and contact with infected surfaces. Due to high transmissibility in places such as clinics, medical offices, buses and offices where there are large crowds, it spread rapidly in Iran and caused the mortality of a significant number of people, especially the elderly with underlying disease. Preventing travel and gatherings, as well as applying house quarantine in Apr 2020, reduced COVID-19 somewhat but then due to lack of attention to social distancing, reducing the use of masks by the people and inappropriate decisions by the national committee on combating coronavirus (NCCC), including reducing the working hours of public offices and shops, reducing the staff of government offices, monopoly on the distribution of essential materials and supplies, the presence of overcrowding in clinics of medical centers, hospitals, and private clinics caused the decline of the disease in the country to decrease. Measures can be taken to prevent the spread of the virus as much as possible, including: rapid detection of infected people, their isolation, contact tracing, quarantine of people over 65 and under 15, protection of the elderly, prevention of gatherings, forcing the use of protective equipment in possible gatherings, and electronicizing public services.

Authors: Kang Hyunwoo , Jang Seyong
Published: July 2021

Background: We aimed to conduct a mindfulness yoga program to treat the psychological problems of middle-aged men by examining the effects of a mindfulness yoga program on depression, self-esteem, and quality of life in this population.
Methods: The participants included 50 middle-aged men (aged 40–60 yr) living in Seongnam-si, Korea. Twenty-five men were randomly assigned to the experimental group and 25 were assigned to the control group. The mindfulness yoga program was conducted twice a week for 12 weeks, and each session lasted approximately 75 min. Before the first session, a pre-test was conducted, after which the program began. Questionnaires were completed after the 4th, 8th, and 12th weeks of the program, and the control group underwent psychological tests at the same time points. A two-way (2 × 4) repeated measures analysis of variance was conducted, and when the interaction effect was significant, a post-hoc test (Bonferroni) was performed.
Results: In the intervention group, depression severity significantly decreased (P<0.001) and self-esteem significantly increased (P<0.01). Furthermore, the intervention group also showed a significant increase in psychological (P<0.001), social (P<0.001), and overall quality of life (P<0.001) among the sub-dimensions of quality of life.
Conclusion: Middle-aged men should be made aware of the usefulness of mindfulness yoga and encouraged to participate in such programs. Mindfulness yoga may be considered as an alternative treatment strategy that promotes the natural healing and management of psychological issues faced by middle-aged men.

Authors: Jia Jin , Liu Mingming , Xue Zhigang , Wang Zhe , Pan Yu
Published: July 2021

Background: We aimed to compare the prediction efficiency of back propagation (BP) network and grey model (GM) (1.1) for mumps infectious diseases and compare the application effect of the two models.
Methods: By calculating the average incidence rate of mumps in January 2014 -2016, we conducted the modeling of the BP time series, GM (1,1) grey model and the combination models of them, and predicted the incidence rate in June 2016 in comparison with the actual one. We compared the quarterly incidence rate to test the two prediction models, and compared the advantages and disadvantages of these models.
Results: R value of BP model was 68.45%, for GM (1,1) was 58.49%, and for combined forecasting model was 86.95%. We used the principal component analysis clustering method to control the samples, and found that the samples were close to the population mean. We found that the GM (1.1) model was more suitable for the prediction of mumps infection mode. We carried out dimension reduction analysis on the model data, and the accuracy of the data after dimension reduction is within the range of Da. For the discrete degree of the data in the combined model, matlab pipeline was used to verify the reliability of the data and results. By calculation after manifold optimization small error probability was P=0.875 and semi mean relative error 2.43%.
Conclusion: BP, GM (1,1) is a better method for modeling the epidemic trend of mumps in China, but the efficiency of prediction is not as high as the combination of them.

A polifonia textual e a busca pela escrita autoral: Análise de fichamentos acadêmicos produzidos por graduandos
Authors: Cavalheiro Douglas André Gonçalves
Published: July 2021

O excesso de informação e a polifonia textual são desafios para a escrita dos discentes recém-ingressos no ensino superior. A dificuldade em organizar as múltiplas vozes presentes nos textos-fontes faz com que muitos discentes, quando solicitados às atividades escritas, exagerem no uso das paráfrases e até mesmo incorram em plágio. O obstáculo do manancial de informações, descrito por Barzotto (2013), necessita ser superado com a experiência prática da escrita de fichamentos. À luz dos tipos de paráfrase expostos por Fuchs (1985), do conceito de polifonia textual de Roman (1992) e da noção de autoria de Possenti (2002), esta pesquisa utiliza a metodologia proposta pela investigação de Barbosa e Fabiano-Campos (2014), que expõe as causas das dificuldades dos discentes em dialogar com as múltiplas vozes presentes no texto-fonte. Serão investigados dois fichamentos de transcrição textual direta e dois fichamentos de resumo produzidos por dois graduandos do curso de Letras da Universidade Federal do Rio Grande do Norte, no semestre remoto de 2020.6. Ambos serão identificados como Aluno 01 e Aluno 02, garantindo-lhes o anonimato. Os resultados preliminares apontam que, mesmo com a padronização acadêmica do fichamento, cada discente seleciona as informações de maneira própria, permitindo verificar indícios de autoria.

Estudo comparativo entre o processo de rosqueamento interno com o macho de corte e o rosqueamento interno com o macho laminador em ferro fundido nodular austemperado: uma abordagem das grandezas físicas
Authors: Haag Claudinei , Amancio Marcos Roberto Morachik
Published: July 2021

Este trabalho tem por objetivo comparar o desempenho de machos de corte e machos laminadores no processo de rosqueamento interno em ferro fundido nodular austemperado (ADI), tendo em vista as grandezas físicas envolvidas. A maioria das peças fabricadas na indústria possui roscas internas utilizadas como elemento de fixação e transmissão de movimento. Todavia, muitas dessas peças são produzidas com materiais de usinagem relativamente difícil, como é o caso do ADI. A obtenção de estabilidade e confiabilidade no processo é de suma importância, quando se trata de rosqueamento interno, pois pode comprometer todo o fluxo anterior, se porventura falhar. Um levantamento do estado da arte evidenciou a necessidade de se caracterizar e mensurar os fenômenos relacionados às variáveis do processo, bem como as características físicas da ferramenta e da peça de modo a prever, da melhor forma possível, a sua aplicabilidade. O estudo aponta para uma superioridade teórica do rosqueamento por laminação, em detrimento ao processo similar por corte, em ADI. Tal afirmação se baseia nas melhores características dessas ferramentas para este processo, como a maior resistência ao torque, por exemplo. Em contrapartida, evidenciou-se a criticidade desta aplicação em função da elevada dureza e abrasão características do material, além da necessidade de uma boa fixação e estabilidade do conjunto máquina-ferramenta. Todavia, há de se realizar ensaios que possibilitem a visualização dos parâmetros estudados e a caracterização do melhor processo, tendo em vista a numerosa quantidade de variáveis envolvidas.

A qualidade na educação tem diferentes definições, que dependem do ponto de vista sob qual é analisado. A gestão da qualidade na educação busca a melhoria dos processos, independente da definição aplicável. O objetivo deste artigo é analisar os benefícios da implementação de um sistema de gestão da qualidade na educação com base no ciclo PDCA. O artigo foi escrito com base em um levantamento bibliográfico. A metodologia PDCA tem quatro etapas: planejar, executar, controlar e estabelecer ações que possam corrigir os rumos e encaminhar para um novo ciclo. Ao planejar, estabelecer objetivos e metas, construir métricas, acompanhar indicadores, analisar resultados e propor planos de ações preventivas ou corretivas, estão sendo identificadas as necessidades de interferência e oportunidades de melhoria na educação. O presente estudo identificou alguns casos onde a aplicação da metodologia PDCA em processos educacionais comprova os estudos teóricos que reforçam a importância da implementação de gestão da qualidade na educação.

Tendências da Gestão do Conhecimento 2.0
Authors: Baldessar Maria José , Quinaud Adriana Landim
Published: July 2021

As Tecnologias da Informação e Comunicação (TICs) são cada vez mais utilizadas em todos os processos de Gestão do Conhecimento (GC). Entre essas tecnologias estão à web 2.0, as tecnologias colaborativas, as ferramentas de mídias sociais como wikis, blogging internos, fóruns, redes sociais empresariais (RSE), entre outros. A web 2.0 também chamada de web social pode ser definida como a segunda geração de serviços da web orientados pela comunidade em que todos podem se comunicar, compartilhar e colaborar. Como consequência, o termo GC 2.0 foi criado para resumir suas tendências e refere-se à aquisição, criação e compartilhamento de inteligência coletiva mediante o uso das redes sociais e comunidades de conhecimento. Assim, através da revisão da literatura o objetivo deste trabalho é apontar as possibilidades da RSE para a GC 2.0 a partir de exemplos de uso. As RSEs são adotadas para melhorar a comunicação, a colaboração e o compartilhamento, além de fomentar a gestão do conhecimento. Constatou-se que as RSEs podem trazer benefícios, mas também representam desafios e riscos. Não se espera esgotar o assunto, a proposta é lançar um olhar sobre a questão e produzir reflexões que possam dar condições de perceber as tendências da GC 2.0 através do uso da RSE.

Published: July 2021

No mundo globalizado, a inovação de produtos e serviços é essencial para a competitividade das organizações. Os fatores intangíveis que cercam os projetos inovadores tornam os riscos ainda maiores e difíceis de serem gerenciados, principalmente quando ocorrem mudanças externa e interna dos cenários que prejudicam os objetivos organizacionais. Portanto, o portfólio de projetos necessita ser periodicamente revisado para garantir que os projetos que o compõe tragam os resultados traçados pela organização. Este artigo apresenta uma abordagem de revisão de portfólio de projetos voltados para a inovação de produtos, serviços e processos, baseando-se em conceitos e teorias da inovação, projetos e gestão de portfólio. Para tanto, o presente estudo expõe-se descritivamente a importância da revisão constante do portfólio de projetos de inovação que influenciam diretamente em tomadas de decisão, gerando mudanças que podem melhorar o desempenho da organização.

O entendimento da gestão contemporânea das organizações vem se mostrando essencial na busca do entendimento dos fatores que levam as organizações ao sucesso no atual mercado, complexo e a cada dia mais competitivo. Neste contexto, é possível notar que existem poucos estudos sobre as práticas e ferramentas de gestão e a aderência destas às organizações. Este estudo investiga a situação das maiores indústrias de alimentos e bebidas de Santa Catarina, e tem por objetivo verificar quais critérios levam seus gestores a escolherem as ferramentas de gestão adotadas e se há aderência ao modelo de gestão vigente. Para verificar os critérios de escolha quanto à adoção das ferramentas, foi realizado um estudo multi-caso através de entrevistas semi-estruturadas e de análise documental em três das maiores indústrias neste setor, e posteriormente os resultados foram utilizados para o cruzamento com as variáveis relatadas no referencial teórico. Entre os problemas identificados destaca-se que os modelos de gestão destas organizações são construídos de acordo com as suas necessidades do momento e não com base em um planejamento. A pesquisa revelou que as empresas pesquisadas não seguem um único estilo de gestão, ou seja, seu modelo de gestão vem sendo construído de maneira tácita, por meio da interação, muitas vezes deficitária, entre as ferramentas existentes na organização e as novas ferramentas escolhidas.

Apresenta-se uma pesquisa quanto à adesão dos moradores de um condomínio residencial no Bairro Juvêve, na cidade de Curitiba- PR , em Setembro de 2008, ao Programa de Coleta Seletiva conduzido pela Prefeitura Municipal da cidade. A metodologia adotada foi dividida em três etapas. A primeira consistiu de pesquisa bibliográfica com objetivo de construir um referencial teórico que sustentasse a idéia da viabilidade econômica e ambiental sobre a geração de renda alternativa a partir da venda da fração reciclável presente nos resíduos sólidos urbanos domiciliares gerados em condomínios. Na segunda etapa, realizou-se uma pesquisa amostral da população residente nos edifícios com suporte de experiências relatadas na área de coleta seletiva em condomínios e do levantamento da realidade do programa na atualidade. Já a terceira etapa, compreendeu a caracterização dos resíduos sólidos urbanos, o seu acondicionamento, a segregação e a pesagem. Os resíduos foram coletados em cada um dos edifícios, separados e pesados; em seguida, selecionados os recicláveis com potencial de venda. Os dados coletados foram utilizados num processo de sensibilização dos moradores para uma adesão qualificada ao programa e serviram para estudo comparativo com os dados da Secretaria Municipal de Meio Ambiente de Curitiba. Os resultados apontam para desafios e oportunidades, associados basicamente à educação ambiental comunitária, à conquista da parceria da sociedade na solução dos problemas ligados ao gerenciamento dos resíduos e à divulgação de informações técnicas e do potencial de negócios e benefícios gerados pela cadeia produtiva da reciclagem.

A alta competitividade no mercado tem exigido que as empresas busquem agregar qualidade a seus produtos em busca de alto desempenho, minimização de desperdícios e redução do custo final do produto. Neste contexto, estrutura-se a metodologia de Controle Estatístico de Processo (CEP). Empresas que fazem uso de CEP necessitam de softwares específicos. Sua utilização, envolve a realização de cálculos estatísticos, construções de gráficos, medição de capacidade de processo, entre outras necessidades. Com isso, precisa disponibilizar recursos financeiros para compra de licença para a utilização dos mesmos, custo este que é muitas vezes repassado ao produto final. A proposta deste trabalho é a utilização de um ambiente computacional livre e gratuito que está disponível na rede mundial de computadores, conhecida como Linguagem R ou apenas Software R para proceder de forma gratuita à utilização do CEP. Neste artigo, procura-se demonstrar a aplicabilidade do CEP, via Software R, dentro do contexto industrial. Um conjunto de dados reais referente à textura superficial de eixos fabricados através de processo de usinagem é apresentado em detalhes.
