Transform with Double Random Phases in the HSV Color Domain
Authors: Shrivastava Aarushi , Sharma Janki B. , Purohit Sunil D.
Published: September 2020

Objective:

In the recent multimedia technology images play an integral role in communication. Here in this
paper, we propose a new color image encryption method using FWT (Fractional Wavelet transform), double random
phases and Arnold transform in HSV color domain.

Methods:

Firstly the image is changed into the HSV domain and the encoding is done using the FWT which is the
combination of the fractional Fourier transform with wavelet transform and the two random phase masks are used in the
double random phase encoding. In this one inverse DWT is taken at the end in order to obtain the encrypted image. To
scramble the matrices the Arnold transform is used with different iterative values. The fractional order of FRFT, the
wavelet family and the iterative numbers of Arnold transform are used as various secret keys in order to enhance the level
of security of the proposed method.

Results:

The performance of the scheme is analyzed through its PSNR and SSIM values, key space, entropy, statistical
analysis which demonstrates its effectiveness and feasibility of the proposed technique. Stimulation result verifies its
robustness in comparison to nearby schemes.

Conclusion:

This method develops the better security, enlarged and sensitive key space with improved PSNR and SSIM.
FWT reflecting time frequency information adds on to its flexibility with additional variables and making it more suitable
for secure transmission.
Research on Crack Detection Algorithm of Mining Car Baffle
Authors: Li Weiwei , Yan Fanlei
Published: September 2020

Introduction:

Image processing technology is widely used for crack detection. This technology
is used to build a data acquisition system and uses computer vision technology for image
analysis. Because of its simplicity in processing, many of the image processing detection methods
were proposed. It is relatively easy to deploy and has a low cost.

Method:

The heterogeneity of the external light usually changes the authenticity of each target in
the image, which will seriously cause the experiment to fail. At this time, the image needs to be processed
by the gamma transform. Based on the analysis of the characteristics of the image of the mine
car baffle, this paper improves the Gamma transform and uses the it to enhance the image.

Result:

It can be concluded that the algorithm in this paper can accurately detect crack areas with an
actual width greater than 1.2 mm, and the error between the detected crack length and the actual
length is between (-2, 2) mm. In practice, this error is completely acceptable.

Discussion:

To compare the performance of a new crack detection method with the existing methods.
The two most well-known traditional methods, Canny and Sobel edge detection, are selected.
Although the Sobel edge detection provides some crack information. The texture of the surface of the
mine cart baffle detected has caused great interference to the crack identification.

Conclusion:

If the cracks appearing on the mine car baffle are not found in time, they often cause
accidents. Therefore, effective crack detection must be performed. If a manual inspection is adopted
for crack detection, it will be labor-intensive and easy to miss inspection. In order to reduce the labor
of crack detection of mine cars and improve the accuracy of detection, this paper, based on the detection
platform built, performs pre-processing, image enhancement, and convolution operations on the
collected crack images of the mine car baffle.
A STUDY ON CUSTOMER RELATIONSHIP MANAGEMENT PRACTICES IN BANKING SECTOR
Authors: Kohli Gautam , Maurya Santosh Kr.
Published: September 2020

Customers play a predominant role in service marketing. Financial services produce a challenging sector and bear professional skill in designing product/services. Out of other financial service, banking is oldest and important financial service sector. Customer Relationship Management (CRM) has a massive influence in service sector, to win and hold customers for long term efficiency. In the early half of 90s, the relationship marketing idea was formally introduced into the service marketing field. Banks found it more beneficial to hold and reward the existing customers as opposed to pursuing new customers. The essence of CRM is to make customers and hold them. Therefore, incurrent situations banks mainly focus on satisfaction of the customers which indicates that the customer is delighted and satisfied by using the service.
Hence the researcher made an attempt in this study to analyze the level of satisfaction on customer relationship management practices in the selected private sector banks. Customer Relationship Management (CRM) is major concern among the service providers especially the banks, if there is lack of understanding. Banks manages their relationships with the customers in their own way. However, the customers’ perception on CRM practices among banks should also be taken into consideration.
The activity of CRM must attend the needs of customers as priority without delay in time; the banks can create a customer data base and make more awareness to customers significantly. Hence the CRM concept may be focused so that the customers are treated as first priority or royally in banking services. Thus, the banks need to focus in improvement of the customer satisfaction in utilizing various modern banking services and should provide more friendly services to customers that make the modern banking activity a pleasure experience for the customer to use.

The luminescent and optical properties of materials based on zirconium oxide obtained by the crystallization of ZrO2 with 0, 2.0, 2.5, 2.8, and 3.7% mol Y2O3 melts were studied. Using Raman spectroscopy, it was found that when the Y2O3 content in the mixture is less than 2 % mol. the material is predominantly a monoclinic ZrO2 structure. For such crystal, a blue-green band with the maximum energy of 2.4 eV was observed in the photoluminescence spectra. This fact, together with the peculiarities of the refractive index and absorption dispersion spectra, indicates the presence of a high concentration of oxygen vacancies and polyvacancies in the sample. With a higher content of Y2O3 in the mixture, the tetragonal modification of ZrO2 dominates in the studied materials; the intensity of blue-green luminescence decreases. A comparative analysis of experimental optical spectra with the first-principle calculations for ideal ZrO2 crystals in the cubic, tetragonal and monoclinic phases was performed.

Развитие методов высокоскоростной атомно-силовой микроскопии дало возможность получать изображение клеток с миллисекундным пространственным разрешением. Вместе с тем сканирующая капиллярная (ион-проводящая) микроскопия позволяет исследовать шероховатую поверхность живых клеток за счет изменения протекающего ионного тока, при этом практически исключая силовое воздействие на клетку. Использование сканирующей капиллярной микроскопии в исследовании раковых клеток открывает новые возможности для скрининга лекарств, для получения новых данных о влиянии изменения внешних условий на кинетику роста опухоли, данных о жизнедеятельности клеток.
Modern methods of scanning probe microscopy make it possible to obtain a detailed pattern of the vital cells topology including cancer cells with a nanoscale spatial resolution during their growth. The development of high-speed atomic force microscopy enabled to produce images of
cells with millisecond spatial resolution. Besides, it is possible to study a rough surface of vital cells by changing the ion current flow without force action on a cell using scanning capillary microscopy (ion-conducting microscopy). The use of scanning capillary microscopy in the study
of cancer cells opens up new opportunities for drugs screening in order to obtain new data on the influence of external conditions changes on the kinetics of tumor growth and the new data on the vital activity of cells.

The porcine reproductive and respiratory syndrome (PRRS) is a viral disease that decreases the reproductive performance in breeding sows and leads to economic losses to the swine industry. The objective of the present study was to identify single nucleotide polymorphisms (SNP) associated to the number of live-born piglets in the first (LBP1) and second birth (LBP2) in breeding sows exposed to PRRS virus. The study included 100 pregnant females of the Landrace(¾)/ Yorkshire(¼) line, 75 of which were infected with the PRRS virus and 25 were free of PRRS. Individual blood samples (6-8 drops) were obtained and spotted onto FTA cards and subsequently processed for DNA extraction, which was genotyped using a 10,000 SNP chip for genomic profile. Resulting genotypes were analyzed using a multi-locus mixed model that detected three SNP associated to LBP1 and five SNP associated to LBP2 (P<0.001). These eight SNP were validated using an associative mixed effects model which included the terms genotype and age of dam as fixed effects, and sire as random effect. Allele substitution effects were estimated using the same model including the term genotype as covariate. The SNP rs81276080, rs81334603 and rs80947173 were associated to LBP1 (P<0.001), whereas the SNP rs81364943, rs80859829, rs80895640, rs80893794 and rs81245908 were associated to LBP2 (P<0.001). Only two SNP were in functional chromosomal regions and the remainder SNP were within an intergenic position. In conclusion, these results suggest the existence of gene variants associated with the reproductive performance of sows infected with the PRRS virus.

El aislamiento en cultivo celular es el método principal para el diagnóstico del virus de la necrosis pancreática infecciosa (VNPI). Aunque es un método confiable, resulta costoso y conlleva tres semanas en proporcionar un resultado. Para disminuir el tiempo en el diagnóstico y aumentar la sensibilidad para la detección del VNPI, el objetivo del presente estudio fue establecer y evaluar el uso de una PCR anidada (PCRa) para un diagnóstico rápido del VNPI. Para ello, se diseñaron dos pares de iniciadores basados en secuencias mexicanas. El primer par (RT-PCR) amplificó un producto de 682 pb y el segundo par (PCRa) 229 pb del gen VP2. Posteriormente, se infectaron 70 crías de truchas arcoíris (Oncorhynchus mykiss) con la cepa virulenta MEX3-CSM-05 a una dosis de 1X105.8 DICC50%/0.02 ml. De cada organismo se colectó el riñón, el bazo, los sacos pilóricos, el hígado, el intestino y las branquias. Para evaluar las pruebas, se utilizaron 26 truchas adultas clínicamente sanas de granjas comerciales del Estado de México. La frecuencia de detección del VNPI mediante RT-PCR en las branquias fue de 87.1 %, en el hígado 61.4 %, en los sacos pilóricos 61.4 %, en el riñón 58.6%, en el intestino 35.7 % y en el bazo 32.9 % (P<0.05). Las muestras negativas a la RT-PCR resultaron positivas en la PCRa. Asimismo, se mostraron positivas las muestras de los órganos de las truchas de campo. En conclusión, la RT-PCR tuvo menor sensibilidad que la PCRa, la cual mostró una sensibilidad del 100%. Por lo tanto, la PCRa es mejor para un diagnóstico confiable del VNPI en peces infectados y enfermos.

Published: September 2020

La pasta de higuerilla (Ricinus communis L) contiene sustancias altamente tóxicas, por lo que se evaluó la efectividad de tres métodos de desintoxicación y su inclusión en dietas para pollos de engorda. Se evaluaron cinco tratamientos (dietas experimentales): dieta testigo a base de maíz y pasta de soya (PS), pasta de higuerilla sin desintoxicar (PH), pasta de higuerilla tratada con autoclave (PHA), pasta de higuerilla tratada con el método químico (PHQ) y pasta de higuerilla tratada con autoclave y método químico (PHAQ). Cada tratamiento se asignó al azar a siete unidades experimentales con 10 pollos cada una. Las variables evaluadas fueron: consumo de alimento (COA), conversión alimenticia (CA), ganancia de peso (GP) rendimiento en canal (RC), rendimiento de pechuga (RP), rendimiento de pierna con muslo (RPM), desarrollo del sistema digestivo, habilidad para caminar (HC), angulación valgus /varus (AVV) y latencia a postrarse (LP). Los pollos alimentados con PH y PHMQ tuvieron menor COA y GP (P<0.05), sin embargo, no hubo diferencias entre tratamientos para CA. Se encontraron diferencias entre tratamiento (P<0.05) para HC y AVV, mientras que en LP no hubo diferencias (P>0.05). Los resultados evidencian que el tratamiento con autoclave (1 atmosfera de presión durante 60 min a 121 °C) disminuyó la toxicidad en la pasta de higuerilla, ya que las aves del tratamiento PHMA tuvieron un comportamiento productivo similar (P>0.05) a las de la dieta testigo.

Published: September 2020

The manipulation of neutral atoms by light is at the heart of countless scientific discoveries in the field of quantum physics in the last three decades. The level of control that has been achieved at the single particle level within arrays of optical traps, while preserving the fundamental properties of quantum matter (coherence, entanglement, superposition), makes these technologies prime candidates to implement disruptive computation paradigms. In this paper, we review the main characteristics of these devices from atoms / qubits to application interfaces, and propose a classification of a wide variety of tasks that can already be addressed in a computationally efficient manner in the Noisy Intermediate Scale Quantum\cite{Preskill_NISQ} era we are in. We illustrate how applications ranging from optimization challenges to simulation of quantum systems can be explored either at the digital level (programming gate-based circuits) or at the analog level (programming Hamiltonian sequences). We give evidence of the intrinsic scalability of neutral atom quantum processors in the 100-1,000 qubits range and introduce prospects for universal fault tolerant quantum computing and applications beyond quantum computing.

The Value of Pre-Operative Testing for COVID-19 in Urological Patients
Authors: Bonatsos Vasileios , Raza Asif
Published: September 2020

According to the World Health Organisation there have been 30,055,710 confirmed COVID-19 cases and 933,433 confirmed deaths across 216 countries globally. The availability of the complete SARS-CoV-2 genome relatively early in the epidemic has enabled the development of tests for the diagnosis of COVID-19. There are two broad categories of SARS-CoV-2 diagnostic tests currently in use or development: (1) Real-time reverse transcriptase polymerase chain reaction (RT-PCR) tests and (2) serology tests. RT-PCR is considered the gold standard and preferred method of diagnosis of acute infection. There is, however, a plethora of laboratory-developed and commercial RT-PCR assays with different gene targets. We discuss the value of pre-operative testing for COVID-19 before urological surgery.

Published: September 2020

Laser scanning is considered as one of the most useful and fast technologies for modelling. On the other hand, the size of scan results can vary from hundreds to several million points. As a result, the large volume of the obtained clouds leads to complication at processing the results and increases the time costs. One way to reduce the volume of a point cloud is segmentation, which reduces the amount of data from several million points to a limited number of segments. In this article, we evaluated effect on the performance, the accuracy of various segmentation methods and the geometric accuracy of the obtained models at density changes taking into account the processing time. The results of our experiment were compared with reference data in a form of comparative analysis. As a conclusion, some recommendations for choosing the best segmentation method were proposed.

Published: September 2020

In recent years, there have been qualitative changes in surveying associated with the use of robotic systems, such as unmanned aerial vehicles. Currently, traditional geodetic and topographic technologies are giving way to high-precision and high-performance systems using robotics. The technology of aerial photography from drones for mapping territories, operational monitoring linear structures, construction sites, as well as for engineering and underground surveys, solving cadastral matters, building realistic three-dimensional terrain models, etc., is gaining more and more popularity in the world. The transition to new technologies entails restructuring not only the methods of determining coordinates, but also the stages of pre-design and design work. The authors describes the capabilities of geographic information systems for automating some stages of field geodetic data cameral processing obtained through using unmanned aircraft. As a result of the study, it was discovered that the marks of the earth’s surface, read from the constructed digital map, are in good agreement with those obtained as a result of the ground-based geodetic survey.

Uma trilogia possível: entre as tramas invisíveis e o jogo necropolítico
Authors: Rago Luzia Margareth , Ambrózio Aldo
Published: September 2020

Trata-se da apreciação da hipótese de se poder reconhecer, enquanto uma trilogia, os longas-metragens O som ao redor (2012), Aquarius (2016) e Bacurau (2019), dirigidos pelo cineasta pernambucano Kleber Mendonça Filho. O fio discursivo que sustenta esta expectativa é sustentado em duas hipóteses: (1) a de que o governo contemporâneo, governamentalidade neoliberal, se apoia no exercício de uma modalidade de governo antiga, o poder pastoral;  (2) o de pensar que existem e convivem, no humano, dois tipos específicos de memória: a que dá sustentação ao presente e ao futuro na forma da projeção e a que demarca uma possibilidade narrativa do passado, enquanto ser ontológico; isso nas ações da escolha, do corte e do encobrimento, próprias a cada sistema de governo político-econômico-social. Com esta perspectiva de leitura, se fará o comentário dos três filmes, cotejando algumas cenas que contribuem para o argumento principal do artigo.
O sertão entre as margens e o centro do mundo atual: notas sobre Bacurau
Authors: Duarte Andre de Macedo , Assis César Maria Rita de
Published: September 2020

Em três momentos, o texto discute o filme Bacurau dos cineastas brasileiros Kleber Mendonça Filho e Juliano Dornelles, tomando como fio condutor a ideia das relações entre margem e centro, entre local e universal. Em um primeiro momento, estabelecemos paralelos entre aspectos do projeto estético-políico deste filme e do movimento do Tropicalismo dos finais dos anos 60, com o qual ele dialoga, sobretudo a partir da ideia de justaposição formal de opostos. Em segundo lugar, mostramos que o enredo do filme articula os polos do regional (o sertão) e do universal (o mundo contemporâneo), entendendo o filme como um diagnóstico do presente esclarecido a partir das noções de biopolítica, necropolítica e neoliberalismo. No terceiro momento, analisamos a construção da vila de Bacurau como comunidade queer, heterotópica e marginal, desviante em relação às normas patriarcais hegemônicas quanto às relações entre os gêneros e quanto à orientação sexual. Na conclusão, argumentamos que o a violência presente no filme não constitui nem um projeto político determinado, nem tampouco serve a propósitos mercadológicos. Por outro lado, a violência contida nos atos de resistência da comunidade está a serviço da garantia de suas formas de vida marginal.

Este artigo aborda as relações econômicas e culturais numa perspectiva de desenvolvimento local e regional aplicado no município de Goiás, considerado de médio porte no estado. Em 2016, a Economia Criativa representou aproximadamente 2,6% do PIB Brasileiro além de apresentar um crescimento de cerca de 70% nos últimos dez anos. Quanto mais investimento público ou privado neste novo segmento econômico, menor é o fluxo migratório de pessoas em busca de serviços públicos em grandes aglomerações urbanas. Em suas várias linguagens e modalidades, a cultura se tornou um bem simbólico tangível e capaz de gerar renda e empregos, contribuindo para o desenvolvimento social, humano e sustentável. O objetivo desse artigo é discutir como se relacionam as dinâmicas da economia e do trabalho local com a cultura advinda do município de Goiás.
O conceito de privacidade diferencial em relação à reidentificação de dados pessoais
Authors: Costa Alexsander Carvalho , Savino Filó Maurício da Cunha
Published: September 2020

O presente artigo tem por objetivo pesquisar uma das lacunas encontradas na Lei Geral de Proteção de Dados Pessoais (Lei nº 13.709/2018), que — se mal implementada em seu programa de conformidade — pode expor os dados de clientes e usuários. O problema de pesquisa se resume ao seguinte questionamento: há fragilidade na proteção de dados do cidadão, em razão dos mecanismos adotados pela legislação Brasileira? Num primeiro momento, tratou-se, brevemente, da anonimização de dados pessoais face à reidenticação, a fim de se poder tratar, posteriormente, da aplicação da privacidade diferencial. O método utilizado na abordagem foi o descritivo-sistemático. O método de interpretação jurídica foi o tópico sistemático. Verificou-se que é imperioso repensar os conceitos sobre segurança da informação de forma a transcender a mera obrigação legal, motivando de igual forma a inovação, a criatividade e a responsabilidade no tratamento de dados pessoais. Conclui-se, em linhas gerais, que a noção de segurança e de sigilo deve permear todas as atividades do tratamento de dados pessoais, desde a concepção de um produto ou serviço.

Espaços de fazer como geradores de uma cultura pautada pela antidisciplinaridade, tolerância ao erro e diversidade cognitiva
Authors: Agustini Gabriela da Costa Aguiar , Santos Jorge Roberto Lopes dos
Published: September 2020

Este artigo propõe que três valores assumem um papel importante no estímulo à geração de novas ideias e ampliação do acesso ao conhecimento, quando incorporados às práticas dos espaços de aprendizagem tecnológica (os espaços de fazer, chamados aqui de labs). São eles: antidisciplinaridade, tolerância ao erro e diversidade cognitiva. O trabalho se insere no contexto marcado pela democratização de tecnologias que permitem a cidadãos fora de grandes centros de pesquisa e da indústria materializar suas ideias, expressar sua visão de mundo, sua criatividade e construir conhecimento a partir da interação com artefatos. E busca contribuir para reflexões sobre a sociedade digital e a necessidade de entendermos os fazeres tecnológicos a partir de seus aspectos culturais.

Authors: Ferreira Camila Camargo
Published: September 2020

Neste artigo, discute-se o uso político da categoria “ideologia degênero” no cenário político brasileiro. As tentativas de compreensão dessefenômeno foram mediadas pelas teorias de Michel Foucault e Giorgio Agambenacerca dos entrelaçamentos de poder, vida e morte na modernidade. Evidencia-seo acionamento da noção “ideologia de gênero” no espaço público como umaestratégia de disputa pelo poder político. Demonstra-se que a introdução docombate à “ideologia de gênero” na agenda política nacional contemporâneaalicerça um projeto conservador antidireitos que intensifica a desvalorização dasvidas dos sujeitos ininteligíveis pela a matriz heteronormativa.
