Automatic Test Pattern Generation using Grover’s Algorithm
Authors: Agrawal Nishant
Published: June 2021

Quantum computing is an exciting new field in the intersection of computer science, physics and mathematics. It refines the central concepts from Quantum mechanics into its least difficult structures, peeling away the complications from the physical world. Any combinational circuit that has only one stuck at fault can be tested by applying a set of inputs that drive the circuit to verify the output response. The outputs of that circuit will be different from the one desired if the faults exist. This project describes a method of generating test patterns using the Boolean satisfaction method. First, the Boolean formula is constructed to express the Boolean difference between a fault-free circuit and a faulty circuit. Second, the Boolean satisfaction algorithm is applied to the formula in the previous step. The Grover algorithm is used to solve the Boolean satisfaction problem. The Boolean Satisfiability problem for Automatic Test Pattern Generation(ATPG) is implemented on IBM Quantum Experience. The Python program initially generates the boolean expression from the file and converts it into Conjunctive Normal Form(CNF) which is passed on to Grover Oracle and runs on IBM simulator and produces excellent results on combinational circuits for test pattern generation with a quadratic speedup. Grover’s Algorithm on this problem has a run time of O(√N).

Structural, Magnetic and Dielectric Analysis of Higher Magnetic Mn Doped Zn-Cr Oxide Nanoparticles
Authors: Balsure S. D.
Published: June 2021

Higher magnetic Mn doped Zn-Cr oxide nanoparticles with general compositional formula MxZn0.95-xCr0.05O have been synthesized by using sol-gel auto combustion technique. Room temperature X-ray diffraction (XRD) technique has been employed to study the structural and microstructural parameters of the as-prepared samples. XRD analysis confirms the phase purity and hexagonal wurtzite structure of all the samples. Replacement of Zn2+ ions by Mn2+ ions shifts peak positions slightly towards the lower angles which in turn expands the lattice lengths ‘a’ from 3.2487 to 3.2528 Å and ‘c’ from 5.2043 to 5.2118 Å. Crystallite size obtained from Scherrer equation was confirmed by Williamson – Hall (W-H) and size – strain plot methods (SSP). Both W-H and SSP methods reveals the tensile type strain for undoped sample and comprehensive type strain for Mn2+ doped samples. Magnetic properties were investigated by using vibrating sample magnetometer. Diluted ferromagnetic behaviour is observed for all the samples and saturation magnetization (MS) increases from 0.0514 to 0.1163 emu/gm. Two-probe technique was employed to understand the dielectric behaviour of the samples as a function of frequency. At lower frequency region, both dielectric constant () and dielectric loss tangent (tan ) shows higher values and decreases with the increasing applied frequency.

Authors: Vashi R. T.
Published: June 2021

Corrosion is the deterioration of metal by chemical attack or reaction with its environment. It is a constant and continuous problem, often difficult to eliminate completely. Prevention would be more practical and achievable than complete elimination. Recently, a huge interested for the use of naturally occurring inhibitors extracted from plants have been emerged. Most of the natural products are non-toxic, biodegradable and readily available due to environmental concerns. The inhibitor is chemically adsorbed on the surface of the metal and forms a protective thin film with inhibitor effect or by combination between inhibitor ions and metallic surface. Corrosion of copper and its inhibition was analyzed by weight loss (Gravimetric), effect of temperature and time of immersion methods. Electrochemical methods such as, Potentiodynamic polarization and Electrochemical Impedance Spectra (EIS) were employed. The protective films formed on metal surface have been analyzed by various techniques such as Scanning Electron Microscope (SEM), Energy dispersive X-ray spectrometry (EDS) and. Atomic Force Microscopy (AFM), Fourier transform infrared spectroscopy (FT-IR), UV-Visible spectra, X-ray Diffraction spectroscopy (XRD), Energy Dispersive X-ray Spectroscopy (EDX), electrochemical frequency modulation (EFM) techniques. The results obtained from weight loss and electrochemical techniques were in good agreement. In this review paper, research works produced over the past background on the corrosion of copper in various medium and their corrosion inhibition by using a various green inhibitors were presented.

Published: June 2021

One of the crucial difficulties we aim to find in computer vision is to recognize items automatically without human interaction in a picture. Face detection may be seen as an issue when the face of human beings is detected in a picture. The initial step towards many face-related technologies, including face recognition or verification, is generally facial detection. Face detection however may be quite beneficial. A biometric identification system besides fingerprint and iris would likely be the most effective use of face recognition. The door lock system in this project consists of Raspberry Pi, camera module, relay module, power input and output, connected to a solenoid lock. It employs the two different facial recognition algorithms to detect the faces and train the model for recognition purpose

Performance Evaluation of Indian “Supply Chain Management” for Manufacturing Sector
Authors: Ali Asad
Published: June 2021

In most organizations, financial results have been the key metric of progress. On a weekly, quarterly, and annual basis, the companies have created reporting structures and financial statements to measure their “supply chain” success. Companies, on the other hand, have struggled to establish successful real-time “supply chain” output analysis and processes. Companies today are working in an ever-changing and volatile world while still competing against global competition. As a result, the principle of “supply chain” management (SCM) has assumed strategic significance. So far, research has shown that many modern businesses have struggled to maximize their “supply chain’s capacity because they have often failed to develop the success metrics required to properly leverage their “supply chain”. Manufacturing companies in India are no exception. The authors of this paper want to suggest whether or not a specific solution is appropriate in the case of Indian manufacturing companies. All required factors influencing a company's “supply chain” success have been incorporated, and the suitability of “supply chain” measurement methods, especially for manufacturing organisations, has been suggested. A scale for “supply chain” efficiency methods was established using data obtained from 100 manufacturing organizations throughout India. The research findings are supposed to have important consequences for Indian manufacturing companies in terms of understanding the factors that contribute to effective SCM operations.

If disease is detected at an early stage, this can increase crop production and provide benefit to farmers. Manual detection of these diseases and pests can be very tedious and time consuming for farmers, especially if they have large farms. We plan to model a crop disease and pest diagnostic system using image processing and deep learning techniques. Crop disease and pest detection can be done using deep learning and image recognition techniques on leaves and other areas of the crop.
A Study of Machine Learning Algorithms for DDoS Detection
Authors: Ahmed Sheikh Shehzad
Published: June 2021

The Internet is used practically everywhere in today's digital environment. With the increased use of the Internet comes an increase in the number of threats. DDoS attacks are one of the most popular types of cyber-attacks nowadays. With the fast advancement of technology, the harm caused by DDoS attacks has grown increasingly severe. Because DDoS attacks may readily modify the ports/protocols utilized or how they function, the basic features of these attacks must be examined. Machine learning approaches have also been used extensively in intrusion detection research. Still, it is unclear what features are applicable and which approach would be better suited for detection. With this in mind, the research presents a machine learning-based DDoS attack detection approach. To train the attack detection model, we employ four Machine Learning algorithms: Decision Tree classifier (ID3), k-Nearest Neighbors (k-NN), Logistic Regression, and Random Forest classifier. The results of our experiments show that the Random Forest classifier is more accurate in recognizing attacks.

As the use of computers in our daily lives increases, so has the need for a natural procedure to interact with the computers. The ultimate aim of human computer interaction is to bring the change that there is always a natural way of interacting with computers coupled with ease and flexibility. Printed and textual media such as prescriptions, invoices, receipts, etc. occupies a large segment of our day-to-day activities and given their volume, it is inefficient to manage them physically as there’s always an associated risk of fading, damage, misplacing, etc. and hence a medium is required for their digital conversion. In this project, we have developed a robust, cross-platform web application that can process the images using PyTesseract based algorithms that can efficiently extract the textual data to facilitate the storage and retrieval of the same. The extracted text can be downloaded as a text file and can also be translated into the desired language. This is an active field of research and thus this paper also discusses various current implementations of the mentioned concept. The Optical Character Recognition framework finds applications in a variety of fields such as business process activities, number plate recognition, KYC and banking processes to name a few.

Authors: Singh Jagroop
Published: June 2021

Calcium as a nutrient is most commonly associated with the formation and metabolism of Bone. Over 99 percent of total Body calcium is found as calcium hydroxyapatite. Ionized calcium is measured by ion selective electrodes. It is also calculated from albumin and globulin values using an appropriate formula. In this study was we will compare measured and calculated ionized calcium in plasma. Material and method : The comparative descriptive study was conducted in Department of Biochemistry of Guru Gobind Singh Medical College and Hospital, Faridkot. 50 patients of arterial blood were enrolled for study. Result: A total of 50 simultaneous arterial blood samples were obtained from 50 patients. Mean age of 45.52±17.45 years and range 18-84 years. Maximum numbers (40%) of patients were from the age group of 34-50 years followed by (24%) in the age group of 18 - 33 years A statistically significant correlation was found between measured and ionized calcium with p value 0.002 and r value 0.418. The difference between measured and Calculated ionized calcium was 0.24mmol/l with p value <0.001 (95% CI of 0.17 – 0.30) which was statistically highly significant. Conclusion; The values of measured and calculated ionized calcium are correlated but there is significant difference in their mean value. Moreover calculated calcium shows significant correlation with total protein and albumin so it is not a reliable indicator in conditions where protein levels are altered.

Published: June 2021

We explored the mediating mechanism of positive reciprocity in the relationship between moral identity and moral behavior, using data obtained from a survey of 567 college students. The results indicate that moral identity internalization, moral identity symbolization, and overall moral
identity were positively correlated with positive reciprocity and moral behavior. In addition, positive reciprocity was positively correlated with moral behavior. Further, moral identity internalization moderated the influence of moral identity symbolization on moral behavior, and this moderating
effect was partially mediated by positive reciprocity. Specifically, the effect of moral identity symbolization on moral behavior through positive reciprocity was strong among individuals with higher moral identity internalization, but weak among individuals with lower moral identity internalization.
Overall, the study findings reveal how moral identity affects moral behavior, which has implications for improving the structure of ideological and moral education in colleges and universities.

A definição de Potencial Químico em fontes didáticas
Authors: Correia Jornandes Jesús , Fonseca Guimarães Gabriel
Published: June 2021

Este artigo tem por objetivo apresentar as análises das abordagens sobre o Potencial Químico em livros de texto, em dicionários, em enciclopédias e em sites da Internet, bem como investigar a apresentação da definição, da conservação, dos seus valores máximo e mínimo e da variação da sua intensidade. A Categoria de Análise das definições está referenciada na abordagem histórica e no Silogismo de Aristóteles. Observou-se que algumas fontes pesquisadas estabeleceram como premissa a relação existente entre o Potencial Químico e a Energia Química para comparar com a relação existente entre a Temperatura e a Energia Térmica. Observou-se também a superficialidade nas abordagens e a prioridade a um tratamento matematizado para associar Potencial Químico a Equilíbrio Químico, em detrimento de uma abordagem epistemológica ou história. Devido à falta de sintonia das definições apresentadas nas fontes pesquisadas, vimos apresentar uma definição para o Potencial Químico. Embora Potencial Químico não seja uma grandeza potencial propriamente dita, a exemplo da Energia Interna, da Entalpia, da Entropia, do Potencial de Helmholtz e do Potencial de Gibbs, entendemos que defini-lo ainda constitui um desafio. Como perspectiva futura, este grupo de pesquisa visa divulgar as conclusões de suas pesquisas sobre as definições em fontes didáticas dos potenciais termodinâmicos para sistemas abertos.
RELACIÓN ENTRE LA FRECUENCIA DE CONSUMO DE FRUTAS Y HORTALIZAS Y EL PERFIL ACADÉMICO: POSIBLES INTERVENCIONES EDUCATIVAS CON VISTA A LA PROMOCIÓN DE HÁBITOS SALUDABLES
Authors: Reyes Gagneten Silvina
Published: June 2021

Este trabalho foi realizado com três propósits: determinar a frequência de consumo de frutas e vegetais (FyV) de estudantes universitários de três carreiras da Universidade Nacional Litoral (Santa Fe - Argentina), relacionar a frequência de consumo (FC) com o perfil acadêmico (PA) dos estudantes e, por fim, determinar as barreiras que estão subjacentes ao consumo de FyH. O estudo foi quantitativo, descritivo e transversal. Foi realizada uma amostragem aleatória simples, entrevistando 242 alunos de duas carreiras com orientação biológica (Faculdade de Biologia e Bacharelado em Biodiversidade) e sem perfil biológico (Arquitetura). A relação entre FC e PA foi verificada por meio da estatística Chi-quadrado. Os resultados obtidos mostram que as principais barreiras para o consumo de FyV, na maioria dos estudantes, são o alto custo e a preparação difícil para o consumo desses alimentos. Por outro lado, evidenciou-se que os alunos de carreiras de orientação biológica apresentam um consumo diário de FyV significativamente maior do que os alunos de arquitetura. Portanto, conclui-se que o perfil acadêmico desempenha um papel importante no que diz respeito à incorporação do FyV na dieta. A implementação de intervenções educativas em carreiras não biológicas apresenta-se como a principal estratégia com vistas à promoção de hábitos saudáveis.
"Poesia com gosto de sangue e mel": História, Memória e Metalinguagem em rastros de resistência
Authors: Guimarães Meira Esmeralda , Pessoa Barbosa Fernanda
Published: June 2021

Este texto tem como objetivo investigar a (meta)linguagem poética e a relação apresentada entre memória, história e literatura em textos literários do escritor baiano Camillo de Jesus Lima. O corpus para este recorte é formado por dois poemas do autor: “Que o coração diga tudo” e “A um Parnasiano”, integrantes do livro Cantigas da Tarde Nevoenta (1955). Para tanto, são utilizadas fontes bibliográficas, sob o enfoque teórico-metodológico do materialismo histórico-dialético. Alguns autores subsidiam tanto os estudos teóricos como metodológicos: Bosi (2000; 2015;2017), Candido (2006), Chalhub (2005), Halbwachs (1968), Hobsbawm (2013) Le Goff (1990) e Marx; Engels (2010). Destarte, os poemas conduzem em suas linhas e entrelinhas duras críticas ao alheamento, à insensibilidade e ao distanciamento da realidade. Sejam nos versos líricos e suaves de “Que o coração diga tudo”, seja na rispidez e rebeldia de “A um Parnasiano”, são expressos os ideais de luta contra à desumanidade, contra as ideologias dos grupos sociais hegemônicos. A lírica moderna, ao voltar sobre si, procura manter claros os seus objetivos, a sua missão, seu descontentamento com os rumos da história.
Da Constituição de 1934 ao golpe do Estado Novo: autoritarismo e disputas políticas em tempos de democracia liberal-burguesa
Authors: Araújo da Paixão Carlos Nássaro
Published: June 2021

Este artigo objetiva analisar a escalada autoritária compreendida entre os anos de 1934 e 1937 e o processo de afastamento político entre Juracy Magalhães, governador da Bahia, e o presidente Getúlio Vargas, que culminou com o golpe do Estado Novo, em 10 de novembro de 1937. Nesse período, foi promulgada a Lei de Segurança Nacional, um dispositivo autoritário em um contexto de formal funcionamento das instituições liberais-burguesas. Após os acontecimentos de novembro de 1935, os decretos de Estado de Guerra e Estado de Sítio, na prática, suspenderam o funcionamento da Constituição de 1934. Por outro lado, havia a movimentação para as eleições que deveriam ocorrer em 1938. Como desdobramento desses fatos, Vargas atuou na perseguição aos seus adversários e antigos aliados. Nessa linha de ação ele estabeleceu intervenção velada na Bahia, em São Paulo e em Pernambuco, a partir da nomeação de executores do estado de guerra, em 29 de abril de 1937. Juracy Magalhães passou a ser investigado e intimidado pelo Coronel Antônio Fernandes Dantas, o executor do Estado de Guerra na Bahia.

A obsolescência na produção de mercadorias: um imperativo material do desenvolvimento do sistema do capital
Authors: Rocha Pereira Mailton , Mascarenhas de Almeida José Rubens
Published: June 2021

Este artigo tem o escopo de refletir acerca da obsolescência de mercadorias, como um processo atrelado ao desenvolvimento das forças produtivas. Nesse sentido, busca-se compreendê-la a luz da analise dos desdobramentos históricos da subordinação das necessidades humanas a reprodução do valor-de-troca. Apresenta ainda a obsolescência planejada do século XX – caracterizada pela redução da vida útil dos produtos de forma deliberada no âmbito da produção – como um expediente resultante desse processo histórico que, em tempo de crise estrutural, aparece como artifício do capital para deslocar a contradição entre produção e consumo.
A criação de escolas como política educacional no município de Vitória da Conquitsa, até os idos de 1945
Authors: Ferreira Elenice
Published: June 2021

O presente texto discorre acerca da criação de escolas como política educacional efetivada no município de Vitória da Conquista, dos primórdios do século XIX ao ano de 1945, e as mudanças ocorridas na educação local decorrentes dessa, tendo como suporte as contribuições teórico-metodológicas propostas pela Nova História francesa. Sabe-se que há muito a historiografia vem considerando que as realidades criadas pela ação do homem, sobre o espaço e no tempo, não podem ser analisadas apenas a partir de seus aspectos globalizantes, mas, também, a partir de suas particularidades e singularidades manifestadas em seu microespaço. Tal postura possibilita a abertura de novas fronteiras interpretativas, de modo a promover outras vias para as pesquisas no campo da História, em especial, da História da Educação. Trata-se do recorte de uma pesquisa de doutorado que investigou as políticas públicas orientadas para o ordenamento da educação no município conquistense em diferentes dimensões: dos projetos de criação das escolas à organização do ensino. Nessa perspectiva, a pesquisa não deixou de reconhecer o município como entidade político-administrativa com vida própria, entretanto, articulado com as ações políticas e educacionais em nível estadual/nacional inerentes ao modelo de Estado federativo.

Purpose: To investigate the relationship between lesion size determined
using mpMRI and histopathological findings of specimens obtained after
mpMRI fusion biopsy and radical prostatectomy. Material and Methods: We
retrospectively analyzed 590 patients with PCa who underwent an MRI
fusion biopsy between 2017-2019. We measured the diameter of suspicious
tumor lesions on diffusion-weighted mpMRI and stratified the cohort into
two groups. Group A included patients with a suspicious tumor lesion
equal and smaller than 10 mm and Group B included those with a
suspicious tumor lesion larger than 10 mm. RP was performed in 53
patients. The patients in Groups A and B were compared according to
their pathological findings obtained with fusion biopsy and RP. Results:
After applying the inclusion and exclusion criteria, Group A consisted
of 144 patients and Group B comprised 146. In Group B, PI-RADS score
determined in mpMRI was higher than Group A, and there was a
statistically significant difference between the two groups in terms of
clinical T-stage. The PCa detection rate and the number of positive
cores were statistically significantly higher in Group B than in Group
A. In addition, there was a statistically significant difference between
the two groups in relation to the biopsy, the ISUP grades and the
presence of clinically significant PCa. In Group B, pathological T-stage
and extraprostatic extension (EPE) and surgical margin (SM) positivity
were found to be higher among the patients who underwent RP. In the
multivariate analysis, the mpMRI lesion size being >10 mm
was found to be an independent predictive factor for SM and EPE
positivity. Conclusion: The radiologists and clinicians should be awared
of the possibility of presence of features that may affect local
staging, such as EPE positivity, in the presence of lesions larger than
10 mm in which prostate cancer is detected.
Silver Nanoparticles as an Effective Antimicrobial against Otitis Media Pathogens
Authors: Yang Rong , Ma Xiaojing , Lang Jiayan , Chen Pengyu
Published: June 2021

Otitis Media (OM) is the most common reason for U.S. children to receive
prescribed oral antibiotics, leading to potential to cause antibiotic
resistance. To minimize oral antibiotic usage, we developed
polyvinylpyrrolidone-coated silver nanoparticles (AgNPs-PVP), which
completely eradicated common OM pathogens, i.e., Streptococcus
pneumoniae and non-typeable Haemophilus influenzae (NTHi) at
1.04µg/mL and 2.13µg/mL. The greater antimicrobial efficacy against
S. pneumoniae was a result of the
HO-producing ability of S.
pneumoniae and the known synergistic interactions between
HO and AgNPs. To enable the sustained
local delivery of AgNPs-PVP (e.g., via injection through perforated
tympanic membranes), a hydrogel formulation of 18%(w/v)P407 was
developed. Reverse thermal gelation of the AgNPs-PVP-P407 hydrogel could
gel rapidly upon entering the warm auditory bullae and thereby sustained
release of antimicrobials. This hydrogel-based local delivery system
completely eradicated OM pathogens in vitro without cytotoxicity, and
thus represents a promising strategy for treating bacterial OM without
relying on conventional antibiotics.

Published: June 2021

Extrusion-based 3D printing of polymeric biomaterials has emerged as a
promising approach for the fabrication of complex tissue engineering
constructs. However, the large pore and feature size lead to low cell
seeding efficiency and limited control of spatial distribution of cells
within the scaffolds. We developed hybrid scaffolds that are composed of
3D printed layers and airbrushed fibrous membranes. Airbrushing time was
adjusted to fabricate low (L), medium (M), and high (H) density
membranes to effectively control stem cell infiltration. When two
distinct populations of stem cells were seeded from top or bottom of the
scaffolds, scaffolds composed of LLL membranes showed gradual mixing of
the cells with depth whereas LHL membranes led to two distinct regions
of cells separated by the H membrane. Our results demonstrate that
fibrous membranes incorporated within 3D printed layers enable
user-defined and spatially controlled cell compositions within hybrid
scaffolds.

DFT and experimental studies on synthesis of bisphenol a: Determination of optimal feed profile in semi-batch reactor
Authors: AKMAN Bugra , ARAS Omur , Kaya Yunus
Published: June 2021

Bisphenol A (BPA) is theoretically synthesized with 2 moles of phenol
and 1 mol of acetone. During the reaction, a stoichiometric ratio or
high acetone concentration causes the formation of by-products. This
situation has been confirmed by density functional theory (DFT)
calculations in addition to the literature information. In these
calculations, the B3LYP method and the 6-311++G(d, p) basis set were
used. DFT calculations show that by-products can be formed in the
synthesis of bisphenol a. The common method used to solve this problem
is to work with high molar phenol/acetone ratios. But this brings
additional operating and investment costs. In this study, semi-batch
reaction experiments were performed which stoichiometric acetone was fed
in reactor with various pulsed modes in the presence of homogenous and
heterogonous catalysts. As a result, it has been shown that high
conversion and selectivity can be achieved by providing energy
efficiency
Modeling phase formation on catalyst surfaces: Coke formation and suppression in hydrocarbon environments
Authors: Wang Peng , Senftle Thomas
Published: June 2021

We develop a simulation toolset employing density functional theory
(DFT) in conjunction with grand canonical Monte Carlo (GCMC) to study
coke formation on Fe-based catalysts during propane dehydrogenation
(PDH). As expected, pure Fe surfaces develop stable graphitic coke
structures and rapidly deactivate. We find that coke formation is
markedly less favorable on FeC and FeS surfaces. Fe-Al
alloys display varying degrees of coke resistance, depending on their
composition, suggesting that they can be optimized for coke resistance
under PDH conditions. Electronic structure analyses show that both
electron-withdrawing effects (on FeC and FeS) and
electron-donating effects (on Fe-Al alloys) destabilize adsorbed carbon.
On the alloy surfaces, a geometric effect also isolates Fe sites and
disrupts the formation of graphitic carbon networks. This work
demonstrates the utility of GCMC for studying the formation of
disordered phases on catalyst surfaces and provides insights for
improving the coke resistance of Fe-based PDH catalysts.
