Authors: Dong Zhipeng , Chen Lei , Song Weixing , Liu Yangshuo , Kang Jianshe
Published: February 2022

In industrial production, bearing is one of the most common and indispensable key components. It is of great significance to prevent safety accidents caused by bearing failure, timely fault type identification, and accurate fault location positioning. In this paper, we propose a method for bearing fault location based on feature visualization of convolutional neural network (CNN). In this method, the bearing vibration signals are transformed into images and the Grad-CAM feature visualization method is used to find the feature regions of the images. Thus, the points of the feature regions are traced back to the one-dimensional signals to roughly locate the faults. It has been proved that the experimental results of bearing fault location by this method are in good agreement with the theoretical values.

Published: February 2022

Ordering and shipping of raw materials is a very important part of a company’s production operations. How to properly arrange the scheme to minimize the transportation and ordering cost is a great concern for enterprises. In this paper, two related models are proposed for the C problem of the Contemporary Undergraduate Mathematical Contest in Modeling: a supplier evaluation model based on Entropy Weight Method, TOPSIS Algorithm and other methods, and an ordering and transportation target planning model based on seasonality analysis and other methods. The former establishes seven supplier importance evaluation indexes based on quantitative analysis from two perspectives of supplier supply capability and business enterprise closeness, analyzes the influence weights of the seven indexes by Entropy Weight Method, and uses TOPSIS Algorithm to calculate the rating ranking of each supplier. The latter is based on the contribution rate of goods, material selection tendency, and corporate interest as the primary factors for enterprises to determine the scheme under different circumstances, and the future supply and demand is predicted through seasonal analysis to establish a target planning model to determine the shopping scheme.

Published: February 2022

Wildfires are an important and heretofore contributor to the climate, especially in some special country,for example southeastern Australia. A large population live in this region, so the wildfires would be dangerous in the extreme. In this paper, we will study how to stop wildfires as quickly as possible. First, The fuzzy clustering analysis is used to classify forest coverage, wind velocity and population distribution. Then In the analysis model level, the elements we considered are the weight of above three factors, made up of some combination of them. In adapting to the changes that may occur in extreme fire events in the next decade, we use the Braess paradox to verify the models with the impact of climate. We supposed the scan cover of the UAV is circular function related with the flying altitude, so linear programming equation could be established at different altitude. We also use this idea to constrain some models of different terrain. It showed that the model has good adaptability with a quick convergence speed by computer simulation. The model was adopted for least-squares data fitting to process experimental data, and a high correlation coefficient was obtained.

„Megfogyva bár, de törve nem...” avagy az ADF túlélésének és megújulásának dinamikája
Authors: Pintér Tibor
Published: February 2022

A Szövetséges Demokratikus Erők, vagyis az ADF egy közép-afrikai dzsihádista szervezet, amely jelenleg a Kongói Demokratikus Köztársaság keleti részén, Észak-Kivuban tevékenykedik. A szervezet eredete Uganda nyugati részére vezet vissza, ahol az ADF a Museveni-rezsim számára egyre nagyobb fenyegetést jelentett, így végül az ugandai hadsereg kiűzte őket. A felkelőszervezet 25 éves fennállása alatt a megújulás és alkalmazkodás módszerét magas szintre fejlesztette, amire az őt ért sorozatos támadások miatt szüksége is volt. Az Iszlám Állammal való kapcsolata pedig új perspektívába helyezheti az ADF megítélését, egyre nagyobb biztonságpolitikai kockázatot tulajdonítva neki.

Authors: Akinradewo Olusola Festus , Bamidle Omojola Anthony , Ogunsemi Deji Rufus
Published: February 2022

Public procurement is the acquisition of works, goods, and services by procuring entities using public funds. The study assesses the level of compliance with the public procurement act (PPA) 2007 in the north-central states of Nigeria. Questionnaires were administered to construction stakeholders in those seven (7) institutions that make up the northern-central. A census survey was used to collect data from contractors, physical planning unit staff, consultants, and procurement administrative units that have executed Tertiary Institutions Fund (Tetfund) projects within 2012-2016. Data collected were analyzed using the relative importance index (RII), Kruskal Wallis, and Dunnett's test. The study revealed that all institutions have a good level of compliance with the tenet and component of the act for the procurement process. The study also shows that there is a significant difference in the level of compliance with the Act by Federal Universities. There was no significant difference in the level of compliance in University of Ilorin (UniIlorin) and Federal University Lafia (UniLafia), University of Abuja (UniAbuja) and Federal University Lokoja (FULokoja), University of Jos (UniJos), and Federal University of Technology Minna (FUT Minna), UniIlorin and FUT Minna, FULokoja and UniJos. The level of compliance of the National Open University of Nigeria (NOUN) is significantly different from other universities. The study indicated that the compliance level is very high, with an overall RII of 80.3% and 91.2% of respondents affirmation of the use of open competitive bidding, which represents fairness, accountability, and openness. The study also affirmed that understanding of tenets of the Act is very high in the study area. The study recommends that there should be a strong understanding between the stakeholders in the construction industry to increase the compliance rate of the PPA (2007) and enhance adequate monitoring of unethical behaviours.
Electrifying the Market: How Traditional Automakers Are Cultivating Electric Brand Identities
Authors: Warnock Caelan
Published: February 2022

This research project looks at the marketing language and brand integration strategies used with electric vehicles (EVs) by traditionally internal combustion-based (ICE) automobile manufacturers. A comprehensive keyword and thematic analysis of manufacturer webpages was conducted to understand the current market positioning of EVs compared with their ICE counterparts. Identified keywords and themes were then considered alongside an NLP sentiment analysis and keyword analysis of 60,291 Twitter tweets. Results indicate Twitter users express more polarized viewpoints with regard to EVs than ICEs, and that EV advertising language is less market specific then that of ICEs. In public discourse, functional attributes highlighted by manufacturers feature more prominently than sustainability-focused attributes, such as environmental impact and the use of sustainable materials. It is apparent manufacturers are still struggling to differentiate their EV products and are being used as a marketing tool by manufacturers to conceptually justify personal automobile ownership and promote CSR priorities.
Benefits, Failures & Implementation of Intranets: An Intranet Action Plan For Goeasy Ltd.
Authors: Dudek Irena
Published: February 2022

Employee intranets have long served as tools to transfer information and strategic initiatives to corporate employees. However, over the last two decades, intranets have evolved into tools for not only top-to-bottom communication, but empower employees to communicate upward, collaborate, ask questions and participate in the virtual culture of the organization. With a rising popularity and dependency on instant messaging, tech-savvy interactions and prompt access to information, workers expect their employers to inform while providing a vibrant, interactive place to work. Although there’s no shortage of available technology to create the ideal portal, developing, implementing, adapting and maintaining an intranet is not an easy task. This applied research project is designed to build a case study for goeasy Ltd., a mid-sized, non-prime lending company, who is scheduled to implement an intranet in Q4, 2021. This MRP draws upon existing scholarly sources and personal observation within the organization to serve as a research foundation for an official procurement plan for the organization’s intranet project.
A New Shade of Green: Transferring Political Power and Issue Emphasis on Twitter
Authors: Andison Samantha Elena
Published: February 2022

Within the Canadian political arena, the Green Party is undergoing a shift away from its traditional emphasis on environmentalism, as a recent change in leadership has led to greater emphasis on a more diversified political platform. This shift can be recognized in the ways in which the Green Party, and their new leadership specifically, has formulated a change in the framing of their policy priorities in communications with the electorate and the world at large. One essential arena in which this framing shift has played out is Twitter, which functions as an important avenue through which political leadership may directly communicate with the general public. This paper seeks to better understand the difference in the Green Party Leaders’ framing of issues on Twitter, as well as the impact of this new framing based on user engagement with the various types of Tweet. Comparing those issues emphasized by previous leader, Elizabeth May, to current leader, Annamie Paul, and the resulting engagement generated by these various policy frames, may lead to a better understanding of how the public is reacting to the shift that is currently taking place within the Green Party.
Multi-Scale Dilated Fusion Network (MSDFN) for Automatic Instrument Segmentation
Authors: Devi Wangkheirakpam , Roy Sudipta , Thongam Khelchandra
Published: February 2022

With the recent advancements in the field of semantic segmentation, an encoderdecoder approach like U-Net are most widely used to solve biomedical image segmentation tasks. To improve upon the existing U-Net, we proposed a novel architecture called Multi-Scale Dilated Fusion Network (MSDFNet). In this work, we have used the pre-trained ResNet50 as the encoder, which had already learned features that can be used by the decoder to generate the binary mask. In addition, we used skip-connections to directly facilitate the transfer of features from the encoder to the decoder. Some of these features are lost due to the depth of the network. The decoder consists of a Multi-Scale Dilated Fusion block, as the main components of the decoder, where we fused the multiscale features and then applied some dilated convolution upon them. We have trained both the U-Net and the proposed architecture on the Ksavir-Instrument dataset, where the proposed architecture has a 3.701 % gain in the F1 score and 4.376 % in the Jaccard. These results show the improvement over the existing U-Net model.
URBANIDAD, BUENAS COSTUMBRES Y EDUCACIÓN: Entre la moral cristiana, la secularización y las tendencias de uniformización en Aguascalientes, 1865-1914
Authors: Ramírez Hurtado Luciano
Published: February 2022

Urbanidad, buenas costumbres y educación. Entre la moral cristiana, la secularización y las tendencias de uniformización en Aguascalientes, 1865-1914 trata de responder a las preguntas: ¿cuáles manuales y libros de texto tuvieron las escuelas públicas y particulares para impartir las clases relacionadas con moral, urbanidad, doctrina cristiana, cartilla política y civismo?, ¿qué instancias vigilaron el cumplimiento de la enseñanza de acuerdo con los programas?, ¿cuál fue el impacto de estos manuales y libros en la sociedad?, ¿qué tanta resistencia hubo?, ¿cuáles fueron las tendencias, cambios y permanencias de las políticas educativas en ese período? Luego de explorar detenidamente leyes, reglamentos e informes sobre instrucción pública en Aguascalientes, así como la currícula relativa a la tira de materias de esos tópicos en los distintos niveles educativos: párvulos, primaria, preparatoria, normal, profesional, se advierte que buscaban el deber ser de los educandos, a la vez que los directores, mentores, profesores y ayudantes tuviesen una reputación intachable y diesen un trato respetuoso a los alumnos. Las disposiciones incluso abarcaron a los padres de familia, con obligación de enviar a los hijos a la escuela y en donde la policía escolar fue implementada para cuidar que los niños no anduviesen vagando por calles y plazas en horas de clase. Se concluye, por lo tanto, en que hubo un claro proceso de secularización en la enseñanza hacia finales del siglo xix y principios del xx, pero con fuertes sustratos religiosos de valores cristianos. Difícil resulta valorar el impacto en la sociedad y en las familias respecto a los temas sobre la moral y la urbanidad contenidos en los manuales y libros (de autores franceses, españoles, venezolanos y mexicanos), pues también se documentan casos de rotundo fracaso. Sin duda, una agenda pendiente. Queda, así, bastante por reflexionar y resolver, ya que muchos de esos problemas trascienden hasta la actualidad.

Published: February 2022

Computer system architecture is one of the subjects that must be taken in the informatics engineering study program. In the study program the graduation of each student in the course is one of the important aspects that must be evaluated every semester. Graduation for each student / I in the course is an illustration that the learning process delivered is going well and also the material presented by the lecturer in charge of the course can be digested by students. Graduation of each student in the course can be predicted based on the habit pattern of the students. Data mining is an alternative process that can be done to find out habit patterns based on the data that has been collected. Data mining itself is an extraction process on a collection of data that produces valuable information for companies, agencies or organizations that can be used in the decision-making process. Prediction of graduation with data mining can be solved by classifying the data set. The C5.0 algorithm is an improvement algorithm from the C4.5 algorithm where the process is almost the same, only the C5.0 algorithm has advantages over the previous algorithm. The results of the C5.0 algorithm are in the form of a decision tree or a rule that is formed based on the entropy or gain value. The prediction process is carried out based on the C5.0 algorithm classification using the attributes of Attendance Value, Assignment Value, UTS Value and UAS Value. The final result of the C5.0 algorithm classification process is a decision tree with rules in it.

Authors: ABOUZAID Kenza , DHAIMY Said
Published: February 2022

Introduction: The aim of this study was to systematically review the debridement efficacy of ultrasonic irrigation compared with sonic irrigation during the endodontic treatment. Methods: An electronic search was undertaken on Cochrane Library, Medline, ScienceDirect and Scopus for articles published between January 2010 and January 2021 using appropriate Mesh terms and key words. The inclusion criteria were systematic reviews or in vitro controlled trials on permanent mature teeth or models simulating the root canal system involving a sonic or ultrasonic irrigation group and a control group of conventional needle irrigation. Two reviewers independently selected articles to include according to the inclusion criteria, extracted data from the articles and assessed the methodological quality of the included studies. The data items were arranged in tables. Results: From 811 studies, 17 in vitro studies and 3 systematic reviews were included. EndoActivator and EDDY were the most sonic devices used, whereas several ultrasonic devices were tested for passive ultrasonic irrigation. Debris removal was assessed either on root canal walls or isthmuses or both. The risk of bias and quality of the selected studies were qualified as moderate to high according to the JBI (Joanna Briggs Institute) and the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) checklists. Overall, the findings confirmed superiority of the two agitation techniques over conventional irrigation and most of the studies showed no significant differences between sonic and ultrasonic irrigation in debris removal, however a moderate level of evidence showed superiority of ultrasonic irrigation. Conclusion: It may be concluded that sonic and ultrasonic activation of the irrigants are beneficial in hard tissue debris removal when compared to conventional needle irrigation, yet, the current data could not find significant differences between the two techniques.

Azadirachta indica A. Juss. (Meliaceae) is a plant whose leaves present several pharmacological activities, among them: antioxidant, antimicrobial and hypoglycemic. The present work aims to determine and validate a spectrophotometric analytical method for quantification of total flavonoids, expressed as rutin, in A. indica leaves and to optimize the extraction conditions of these flavonoids. For the selection of the spectrophotometric method, four analytical methods were investigated. The method selected as the most efficient, simple, fast and sustainable has been validated and optimized. The validation was performed according to criteria of national and international regulatory agencies. Box Behnken design (33) and the response surface methodology (RSM) were used to estimate the best extraction conditions. The analytical method that met the study criteria consisted of ultrasound-assisted extraction (UAE) of the plant material in hydroethanolic solution, at a temperature of 60 ºC, for 30 minutes, followed by filtration, dilution of the extract in ethanol/0.02 M acetic acid solution (99:1) and absorbance reading in a spectrophotometer at 364nm. In the validation stages, this method was shown to be linear (linear interval - 20 to 80 μg/mL), precise (intraday and interday), accurate (mean recovery of 120.8%), robust and selective (absence of matrix effect). The best conditions for the UAE process were: Ethanol content 30% (p/p), plant material/solvent ratio 0.2 g/mL and extraction time of 33 minutes. The spectrophotometric method and the UAE conditions determined in this study are suitable for use in the quality control of plant drugs and ethanol extracts from the leaves of Azadirachta indica.

Objetivou-se obter estimativas de herdabilidade e tendências genéticas de bovinos da raça Caracu sobre variáveis de pesos corporais. Os animais eram pertencentes ao estado de Mato Grosso, com informações sobre pesos nascimento, pesos ajustados para idades aos 240, 500, 830 dias de idade. Os grupos de contemporâneos foram formados pela combinação dos efeitos fixos de ano e época de pesagem e sexo do animal. Para a estimação dos componentes de variância foi utilizado modelos lineares misto com efeitos fixos de grupo de contemporâneos, efeitos aleatórios genético aditivo, genético materno (para os pesos pré desmama) e residual, utilizou o método da máxima verossimilhança restrita e as equações de modelos mistos para a predição de valores genéticos. As tendências genéticas foram estimadas por meio de regressão linear dos valores genéticos dos animais em função do ano de nascimento, para machos e fêmeas, separadamente. As estimativas de herdabilidades diretas foram de 0,24 a 0,45 para todos os pesos demonstrando a presença de variabilidade genética. As tendências genéticas foram estimadas para o peso nascimento de -0,169 e -0,016, peso a desmama de 0,117 e 0,138, peso ao sobreano de 0,430 e 0,341 e peso adulto iguais a -0,541 e -0,176 quilogramas por ano, respectivamente, para machos e fêmeas. As herdabilidades e a tendência genética indicaram que diante a seleção direta para as características ponderais, obtém uma resposta esperada para a raça Caracu, denotando um aumento de velocidade de crescimento na recria e evidenciando a desmama como um critério de seleção.

O guaraná da Amazônia é utilizado na suplementação humana principalmente devido a presença de metilxantinas e polifenóis representados por cafeína (CF), teobromina (TB), catequina (CT) e epicatequina (EP), que conferem propriedades energéticas e antioxidantes aos seus produtos a base das sementes. A frutificação do guaranazeiro não é padronizada, tornando a colheita dispendiosa, pois é realizada manualmente e de forma escalonada. Assim, objetivou-se investigar a produção de frutos e o teor de CF, TB, CT e EP ao longo da safra de 2017. A produção dos frutos foi analisada diariamente e foram realizadas 12 colheitas num intervalo de 63 dias, sendo colhidos somente os frutos maduros e abertos. Metilxantinas e polifenóis foram quantificados por cromatografia líquida de alta eficiência (HPLC) a partir de frutos selecionados frutos de cinco momentos de colheitas, com intervalo de 14 dias. As quantidades de CT, EP e TB foram maiores quando os primeiros frutos amadureceram. Já a cafeína, se manteve praticamente estável durante todo o período avaliado. Nas primeiras quatro semanas a colheita precisou ser realizada duas vezes por semana, a partir daí, semanalmente. Posteriormente, foi necessário somente uma colheita por semana até o final da safra. A quantidade de frutos colhidos em cada colheita sofreu alterações e também alcançou um pico de produtividade na décima colheita, após 104 dias da polinização.

The infectious spleen and kidney necrosis virus (ISKNV) belongs to the genus Megalocytivirus (MCV), a group of double-stranded DNA genome viruses. The aim of this study was to retrospectively analyze samples from suspected foci of MCV infection in freshwater fish in Brazil. Samples were collected from infected fish between 2017 and 2021. Phylogenetic analysis revealed 2 groups of MCV circulating in the country. A genetically homogeneous group formed a clade with ISKNV samples from different parts of the world. Only 2 of the sequences from the state of Goiás showed a small genetic distance when compared to the larger group in the same clade. This study describes the validation of 3 qPCR methods and the presence of MCV in Brazil since 2017, including a genotype not previously described.
