Lineage 2 West Nile virus (WNV) caused a vast epidemic in Europe in 2018, with the highest incidence being recorded in Italy. To reconstruct the evolutionary dynamics and epidemiological history of the virus in Italy, 53 envelope gene and 26 complete genome sequences obtained from human and animal samples were characterised by means of next-generation sequencing. Phylogenetic analysis revealed two Italian strains originating between 2010 and 2012: clade A, which apparently became extinct in 2013–2014, and clade B, which was responsible for the 2018 epidemic. The mean genetic distances in clade B increased over time and with the distance between sampling locations. Bayesian birth-death and coalescent skyline plots of the clade B showed that the effective number of infections and the effective reproduction number (Re) increased between 2015 and 2018. Our data suggest that WNV-2 entered Italy in 2011 as a result of one or a few penetration events. Clade B differentiated mainly as a result of genetic drift and purifying selection, leading to the appearance of multiple locally circulating sub-clades for different times. Phylodynamic analysis showed a current expansion of the infection among reservoir birds and/or vectors.
FORMAÇÃO E REPRODUÇÃO DO MERCADO DE MÃO DE OBRA LIVRE NO BRASIL: EXPROPRIAÇÕES E AUTORITARISMO NO CAPITALISMO PERIFÉRICO
Authors: DE ALMEIDA EVERTON WERNECK
Published: September 2019

Este ensaio teórico versará sobre o processo de formação do mercado de trabalho no capitalismo central e no capitalismo periférico, mais especificamente no Brasil. Trata-se de repensar a ideia de que, após a denominada “acumulação primitiva”, a dinâmica do modo de produção capitalista seria capaz de, por si só, produzir e reproduzir a força de trabalho necessária para o seu processo de acumulação. A princípio, pensávamos que somente formações sociais pré-capitalistas lançavam mão de procedimentos extraeconômicos visando à extração de trabalho excedente desses estratos subalternos. O presente escrito visa problematizar tal noção, realçando o papel desempenhado pelo poder político, já sob consolidada dominação burguesa, na produção de contingentes expropriados. Neste ponto, países centrais e países periféricos guardam grandes diferenças entre si, sendo essa questão da formação de contingentes de mão de obra “livres” um dos momentos em que as citadas distinções irão aflorar, revelando a face autoritária do capitalismo na periferia do sistema. Palavras-chave: Acumulação primitiva; Mercado de trabalho; Expropriações; Capitalismo periférico
A COTA, O PARTIDO E A MULHER: DUAS DÉCADAS DE VIGÊNCIA DAS COTAS ELEITORAIS DE GÊNERO SOBRE AS CANDIDATURAS PARTIDÁRIAS NAS ELEIÇÕES MUNICIPAIS PROPORCIONAIS (1996-2016)

Published: September 2019

Este artigo analisou a evolução da presença das mulheres como candidatas nas listas partidárias por padrões ideológicos no eixo direita-esquerda. Para tanto, por meio de uma metodologia quantitativa, comparou-se os percentuais médios de candidatas por eixo ideológico partidário e a razão entre o total de candidatas e de candidatos nos últimos cinco pleitos municipais proporcionais (1996-2000-2004-2008-2012-2016) no intuito de responder as seguintes questões: as cotas eleitorais de gênero mitigaram a sub-representação feminina? Partidos de esquerda tenderam a lançar mais candidatas que os de direita na disputa para vereador? São os pequenos partidos os responsáveis pelo maior percentual de candidatas? Pode-se constatar que houve uma a mitigação da sub-representação descritiva, porém, os partidos possuem comportamentos distintos no cumprimento do instituto das cotas eleitorais de gênero, mais pelos seus respectivos tamanhos do que pela localização no eixo ideológico direita-esquerda.

Os achados desvelam as tensões em relação a proposição de projetos e o apoio de candidaturas, reforçando as ambiguidades que atravessam o cotidiano do movimento carismático católico.
PARA QUEM É A REFORMA DO ENSINO MÉDIO: UM ESTUDO SOBRE A VISÃO DO JOVEM BRASILEIRO NO CENÁRIO DE MUDANÇAS EDUCACIONAIS
Authors: Alves Sauma Janderson
Published: September 2019

Diante do atual cenário de reformas instituídas pelo governo, a educação não esteve fora desse círculo de mudanças, quando em 2016 o governo lançou a público a então Medida Provisória 746, referente a mudança curricular do ensino médio brasileiro. Com a proposta de ser uma reforma que elenca desejos de alunos e professores, a medida aprovada no ano de 2017 teve diversas críticas e protestos, não por menos, haja a vista que, dos motivos elencado pelo então ministro da educação Mendonça Filho, não partiam das mesmas reinvindicações que a classe dos jovens e professores exigiam. O que se pretende aqui é demonstrar por vias de análises conjunturais de censo aplicado com alunos do ensino médio, além de notícias que ocorreram durante a criação da medida junto com o período de protestos a demonstração simples e plausível de que a atual reforma não procurou um diálogo com aqueles que estão no âmbito escolar. Essas bibliografias comprovam que o adolescente ingressante no ensino médio ainda não é levado a sério, sendo silenciados perante as diversas ocupações escolares no ano de 2016. A imposição da reforma do ensino médio apenas reforça que precisamos aprender a ouvir a juventude brasileira.
NATUREZA E CULTURA: DA REJEIÇÃO À (RE)CONSTRUÇÃO
Authors: Di Lourenço Esteves Janaína , Do Couto Neto Geraldo Homero
Published: September 2019

Partindo das problematizações acerca do dualismo entre natureza e cultura, nosso objetivo é realizar um diálogo entre as mesmas nos âmbitos antropológicos e históricos. As reflexões mais recentes estão mudando o curso das disciplinas, num momento em que a crise climática e o antropoceno colocam novos desafios para as humanidades como um todo e para as visões insulares das ciências humanas e ciências naturais. Dessa forma, mapeamos e relacionamos as formas pelas quais podemos encontrar alternativas de abordagens menos dualistas para um campo de estudo que se pretende mais dialógico. Tais abordagens se constituem, principalmente, numa reformulção teórica e metodológica, assim como numa reorientação do que é ser humano e de como conhecer o mundo.
Making sense of the 2016 water crisis in San Andres, a Colombian Caribbean Island
Authors: Velasquez Carolina
Published: September 2019

In October 2015, the Colombian Institute of Hydrology, Meteorology and Environmental Studies (IDEAM) declared that the El Niño phenomenon had reached severe conditions, and later, on July 13, 2016, reported that conditions had returned to normalcy. One of the affected areas was San Andres, a touristic drought-prone Colombian Caribbean island. On April 2, 2016, there were 11 road protests spread throughout the south-center of the island where the Raizales, an ethnic-minority group, and people from poor neighborhoods burned tires, blocked streets, and held up signs saying, “We need water.” That was the official beginning of the water crisis, which had by then affected 14,000 people. On April 15, the local government, for the first time in its history, declared a State of Public Calamity, attributing the causes of the lack of water to the El Niño phenomenon. The government established the El Niño phenomenon as the only trigger of the crisis, but the ways in which the community framed and understood the water crisis were overlooked. Acknowledging the importance of the community voice, this research analyzes the way people were affected and public officials made sense of the water crisis. Thirty-four semi-structured interviews were conducted in August, 2016 with a variety of stakeholders. The results show that officials were more inclined to frame the water crisis as a problem triggered mainly by technical and natural issues. On the community side, people framed the water crisis as a problem where social issues like justice predominated. This study helps to expose and understand the complexity of the San Andres water crisis and ultimately contributes to the prevention of repeated or more severe crises.
Las formas del trabajo infantil en la región de la Triple Frontera entre Argentina, Brasil y Paraguay
Authors: Zsögön Cecilia
Published: September 2019

Las prácticas englobadas bajo la categoría de “trabajo infantil”, incluidas sus peores formas, adquieren un carácter distintivo en una región periférica transfronteriza. El presente artículo analiza las principales formas de las actividades económicas que realizan niños, niñas y adolescentes en la región conocida como Triple Frontera, en el límite que une -y separa- Brasil, Argentina y Paraguay. Estas formas abarcan desde la colaboración en el hogar hasta la explotación sexual comercial en condiciones de esclavitud. Hacemos especial hincapié en el anclaje territorial que contribuye a determinar la especificidad de estas prácticas en la región, así como la invisibilización y naturalización que contribuyen a su perpetuación.
Turismo, Ferrovia e Publicidade: a construção de sentidos e significados nos cartazes ferroviários do Reino Unido (1890-1970)
Authors: Frossard Miriane Sigiliano , Fraga Carla
Published: September 2019

O objetivo deste estudo é analisar, exploratoriamente, os sentidos e significados relacionados ao turismo presentes nos anúncios publicitários (cartazes) das ferrovias no Reino Unido a fim de apreender as representações a respeito do turismo e do transporte ferroviário em seu contexto sociocultural e histórico. Para isso, tomou-se da semiótica de Roland Barthes como método de análise de um conjunto de seis cartazes ferroviários produzidos e veiculados no Reino Unido no período de 1890 e 1970, tendo como base a teoria da transferência de significados apresentada por McCracken. O estudo evidenciou a forte relação histórica entre o desenvolvimento do transporte ferroviário e a evolução do turismo, estando a ferrovia atrelada não apenas a serviços como hospedagem e agenciamento, mas também como promotores de destinações turísticas e de seus significados simbólicos. Também se observou que, apesar de geralmente explorar atrativos e destinos, em alguns momentos, significados utilitários próprios dos meios de transporte foram ressaltados, como pontualidade e rapidez.

Este artigo visa analisar a evolução das reuniões associativas internacionais e do número de delegados das reuniões associativas internacionais, assim como compreender, de forma exploratória, se os planeadores de reuniões, tendem a ir de encontro aos requisitos esperados pelos principais intervenientes numa reunião internacional. Para efeitos da realização do estudo, foi desenvolvida uma análise exploratória de dados, no período de 2002 a 2009, provenientes da International Congress and Convention Association (ICCA). Os resultados mostram que, os Estados Unidos e a Alemanha lideraram ininterruptamente o ranking de países com maior número de reuniões associativas e delegados e, indiciam fortemente que, os planeadores de reuniões tomam em consideração os interesses dos executivos das associações e dos respetivos participantes, no processo de escolha do local da reunião associativa internacional. Os resultados têm implicações importantes na postura a adotar pelos delegados e executivos das associações, assim como no desenvolvimento de políticas públicas.
La littérature indonésienne en traduction française
Authors: Chambert-Loir Henri
Published: September 2019

French translations of Indonesian literature published between 1958 and 2019, in France as well as in Indonesia, amount to a total of 54 titles. This article reviews these translations, focusing on some particularly significant titles and commenting on the quality, often deficient, of some of them. Translators have a great importance in the choice of translated titles, but the 54 titles as a whole do not present a representative panorama of Indonesian literature. Also discussed are translations of ancient Malay literature, of other languages of Indonesia, and of Malaysian literature. The number of translations of modern Indonesian literature into French is finally compared with that of the translations of this literature into other foreign languages and the translation of other Asian languages into French.
Tools of promoting „energy-crops”
Authors: Kondor Attila , Antal József
Published: September 2019

The utilisation of renewable energy sources have come to front with the decreasing fossil fuel stocks, the unsolved problems and fears of nuclear energy and so the cumulating energy dependence. In Hungary the potential of biomass is the largest in renewable energy sources.During our examinations, we analysed the promotion of producing energy crops in Szabolcs-Szatmár-Bereg county. With the examination of the territories involved in energy crop subsidies it can be stated that the energy crop subsidy had its promoting role only on those areas where because of the bad soil conditions the energy crop producing is more profitable than other alternative (non energy) crops.The expected growth rate of energy plantations will be low, according to the low rate of subsidy intensity (40-60%). The uncertainty of direct area payments decreases the calculability that cuts back the favour of investment in short rotation forestry planting.
Farms in the system of European supportpolicy
Authors: Nagyné Demeter Dóra
Published: September 2019

Common Agricultural Policy (CAP) has been having a great past, it is over numerous direction and structure changes in the last half century. After the Treaty of Rome, the harmonization of he agricultural structure and the production of Member States has been launched, during which the economic changes in the world and in Europe were continuously being kept track of. By using common experience, they strived to develop an agricultural sector that supplies the Member States of the Community with food, while the competitiveness and living circumstances of family farms are being improved. The general directions outlined in Stresa in 1958 were significantly redrawn owing to the transformed market conditions and EU accessions. The subsidization of family farms and the improvement of their profitability are having a stressed importance nowadays, too. Our country, as the fully qualified member of the European Union tries to meet its obligations undertaken in the accession treaty and therefore to develop an agricultural sector carrying out diversified agricultural production with a healthy age structure. The aim of the study is to specifically overview the issue of common agricultural policy by stressing the main development points and to introduce the Hungarian conditions of family farms. Besides, there will be an evaluation of the research works examining the income conditions of family farms in the North Great Plain region.
Academicians' Acceptance of Online Learning Environments: A Review of Information System Theories and Models
Authors: Gunasinghe Asanka , Hamid Junainah Abd , Khatibi Ali , Azam SM Ferdous
Published: September 2019

Aim of this paper is to review technology (IS) acceptance theories and models,
recognizing empirical evidence available to support the suitability of each theoretical model in explaining academicians’ acceptance of online learning technology. Understanding the factors influencing system usage is crucial for decision-makers to recognize potential user needs and concerns, which could be addressed during the development phase of a system. Thus, for decades, researchers have been trying to understand why people accept new technologies. As a result, a wide variety of theories and models explaining the concept of technology acceptance. Some prominent theoretical models explaining technology acceptance are, “Theory of Reasoned Action”, “Diffusion of Innovation theory”, “Theory of Planned Behavior”, “Social Cognitive Theory”, “Technology Acceptance Model”, “Model of PC Utilization”, “Motivational Model”, “Unified Theory of Acceptance and Use of Technology”, “UTAUT 2”, “UTAUT 3”. The concept of academic’s acceptance of online learning technology can be explained through several determinants that are operationalized through above information systems models.
Review of Ulrich Hintze, Theoria Generalis: Das Wisen des Politischen
Authors: Gottfried Paul
Published: September 2019

Has Ulrich Hintze succeeded in producing a "general political theory"? At the least, the author has provided a useful tour of the thought-provoking work of thinkers such as Hermann Heller, Hermann Schmitz, and Ludwig von Mises. Along the way, Hintze makes extensive use of Mises to create a theory of the state, taking aim at anarcho-capitalists.
Engagement of Executive Outcomes in Sierra Leone – utility assessment
Authors: Maciąg Mateusz
Published: September 2019

Objectives

The article explores combat related Private Military Companies (PMCs) that are authorised to engage in the forefront of the battlefield as dedicated force multipliers.

Methods

To supplement empirical data with qualitative observation, the methodology applies the case study and observation method. Considering assistance in conflict termination as a dependent variable, the methodology evaluates the case study of Executive Outcomes in Sierra Leone and, to impose a framework for observation, deconstructs that case with seven independent variables: competence, effectiveness, flexibility, field cooperation with conventional forces, cost efficiency, impact on military and the state-to-PMC balance.

Results

The methodology indicates what factors were prevalent in effective conflict management and what indicators entailed chal- lenges. The results advocate for the competence, flexibility, effectiveness and cooperation with armed forces to be deemed conclusive in positive PMC engagement, whereas the cost efficiency, impact on conventional military and the state-to-PMC balance require improvement.

Conclusions

Since governments have continued to be hesitant (justified either by financial, geopolitical or social incen- tives) towards overseas military operations where asymmetric warfare is taking place, PMCs stepped in to fill the se- curity void. Therefore, this paper argues that PMCs are here to stay; however, the literature hasn’t rigorously ex- plored the subject matter to determine whether indicators of success and failure exist to evaluate the PMC outcome. This paper also precipitates natural outgrowth in the scholarship by composing the benchmark that synthesises relevant data.

Contribución al estudio de las transiciones orden-desorden orientacional en la aproximación de campo medio
Authors:   , Mirasso Claudio Rubén
Published: September 2019

Cuando uno se halla dispuesto a estudiar un cierto modelo físico sabe de antemano que, en la mayoría de los casos, puede intentar buscar resultados razonables (que muchas veces terminan siendo buenos y hasta a veces muy buenos) utilizando formalismos sencillos y aproximaciones importantes, o intentar llegar a mejores resultados a costa de utilizar modelos más complejos (con aproximaciones más exactas). En este trabajo hemos elegido el primero de los criterios por lo siguiente: a través de la evaluación de la bondad del método, avalada por la experiencia acumulada en nuestro grupo de trabajo, se sabe que esta aproximación da resultados satisfactorios, aún para regiones cercanas a la de la transición; para interacciones de largo alcance como lo son las dipolares y cuadrupolares. En el caso de interacciones de menor alcance, como la interacción espín-espín, no es de esperar buenos resultados cerca de las transiciones de fase, pero sí de que los rasgos topológicos de los diagramas de fases, lejos de estas regiones, sean suficientemente buenos como para poder explicar algunas observaciones experimentales. Esto nos motivó a utilizar la aproximación de campo medio en el estudio de algunos modelos aplicados a sistemas que presentan transiciones de fase del tipo orden-desorden orientacional.
Registros en cristales fotorrefractivos BSO
Authors:   , Lasprilla Álvarez María del Carmen
Published: September 2019

Uno de los principales objetivos de este trabajo es estudiar el empleo de un cristal BSO como medio de registro de imágenes iluminadas incoherentemente. En el proceso de descodificación o reconstrucción de las imágenes registradas se analiza la variación de la polarización del haz de lectura producida por la modulación de la birrefringencia inducida en el medio. El interés principal en el estudio de la polarización del haz de lectura es controlar el contraste y así optimizar la imagen reconstruida a la salida del sistema. Para ello, se empleó un conversor óptico incoherente a coherente sin soporte holográfico y en configuración transversal, el cual puede considerarse como un subsistema óptico de algún procesador más general. Mediante un sencillo modelo fenomenológico que toma en cuenta la interacción flujo-molécula, se discutirán luego las principales características observadas ya sea con o sin sintonía. Finalmente, se analizan los resultados obtenidos así como las ventajas y desventajas del método utilizado y sus posibles aplicaciones. (Párrafo extraído del texto a modo de resumen)

We conducted the survey of the adult population (n = 37) at age of 33.82 ± 0.82 years, living in ecologically unfavorable conditions (influence zone of industrial emissions) of Chusovoy (Perm Territory). The comparison group included 25 people from the area with acceptable sanitary and hygienic indicators of atmospheric air quality. The average age of the comparison groups surveyed was 35.25 ± 1.24 years. The study of features of the immune status of the examined individuals exposed to the external effects of vanadium fine dust have been showed a decrease in phagocytosis, expression of the level of interleukin-10 and production of serum immunoglobulin A class (IgA). Both the odds ratio analysis and mathematical modeling showed a significant increase in the content of class G immunoglobulin (IgG) and class M immunoglobulin (IgM) (R2 = 0.67–0.70, p < 0.05) with an increase of vanadium concentration in the blood. At the same time, the study of the metal content in the blood of the observed group as compared with the permissible level showed higher concentrations. We revealed the features of gene polymorphism associated with an increase in the prevalence of the minor homozygous genotype for the SULT1A1 and CYP1A1*3 genes — the immune regulation (MTHFR), detoxification and endothelial regulation (VEGFA) genes. The results of the analysis of twenty-nine polymorphic genes revealed the key genes of the male and female subgroups of the main group, which prevalence of polymorphisms was significantly different from that of the comparison group (p < 0.05). At the same time, the genotypes of working men of the main group were characterized by a significant predominance of the variant allele compared to the control group (HTR2A, MTHFR, CYP1A1, FAS, CPOX, TNF). The genotypes of working women were characterized by the dominance of such polymorphic genes as MTHFR, MMP, ANKK1, ZMPSTE, TNF.

Data mining is a lively process used in many leading technologies of this information era. Eclat growth is one of the best performance data mining algorithms. This work is indented to create a suave interface for Eclat growth algorithm to run in multi-core processor-based cloud computing environments. Recent improvements in processor manufacturing technology make it possible to create multi-core high performance Central Processing Units (CPUs) and Graphics Processing Units (GPUs). Many cloud services are already providing accessibility to these high-power processor virtual machines. The process of blending these technologies with Eclat Growth is proposed here in the name of “Multi-core Processing Cloud Eclat Growth” (MPCEG) to achieve higher processing speeds without compromising the standard data mining metrics such as Accuracy, Precision, Recall and F1-Score. New procedures for Cloud Parallel Processing, GPU Utilization, Annihilation of floating point arithmetic errors by fixed point replacement in GPUs and Hierarchical offloading aggregation are introduced in the construction process of proposed MPCEG.

The accurate design of spur gear drive has a tremendous impact on size, weight, transmission and machine performance. Also, the demand for lighter gears is high in power transmission systems, as they save material and energy. Hence this paper presents an enhanced method to solve a two stage spur gear optimization problem. It consists of a mathematical model with a nonlinear objective function and 11 constraints. A two stage spur gear is considered. To obtain minimum volume of spur gear drive is objective of the problem. The considered design variables are: Module, number of teeth, base width of the gears and, shaft diameter and power. Besides considering regular mechanical constraints based on American Gear Manufacturers Association (AGMA) requisites, six more additional critical constraints on contact ratio, load carrying capacity, power loss, root not cut, no involute interference and line of action are imposed on the drive. Nature inspired optimization algorithms, namely, Simulated Annealing (SA), Firefly (FA) and MATLAB solver fmincon are used to find solution in MATLAB environment.

In this paper, performance metrics of rate adaptive and margin adaptive bit loading algorithms is simulated and analyzed to improve the data rate in undersea communication channel. In fault tolerant undersea communication, achieving higher data rate is a challenge. Bit loading algorithms have proven efficient with limited power budget. An optimal bit loading algorithm with low complexity and fast convergence for rate adaptive and margin adaptive problems with bit error rate (BER) constraints will increase the data rate and reliability of the system significantly. The simulation has been carried for submarine audio channel with a bandwidth of 0-20kHz considering ambient noise and thorps attenuation model for 16 subcarriers. Three different approaches such as Chow, Campello and Ant Colony Optimization are simulated for margin adaptive and rate adaptive criteria. Simulation results show that, for margin adaptive conditions Campello and ACO algorithms reduce energy by a factor of 71.50% and 13.05% with respect to Chow’s algorithm with an input of 90 bits. It was also observed that for rate adaptive conditions, Chow and ACO algorithms gave marginally increased bit rate compared to Campello algorithm with energy fixed at 8.35J. Campello and ACO algorithm execution time were reduced by a factor of 67% and 87.10% respectively as compared to Chow’s algorithm.

Agriculture plays a major part in the economic growth of India . As there is high demand for quality fruits in the market fruit grading process is considered as very important. Fruit grading by a human may cause inefficient and it may also leads to some error. Another problem is labour intensive and to solve the above problems agricultural industries introduce many automated grading systems. In this paper a concept was introduced to get quality fruits by observing its color, measuring its size and weight. Due to cost and inaccurate process, sorting tons of quality fruits to produce food products made from fruits is an another problem that is faced by most of the agricultural industries. Here a sorting process is introduced where the image of the fruit is captured and analyzed using image processing techniques and the defected fruit is discarding by this process. The main aim of this paper is to do the quality check of the fruits within a short span of time.

The construction industry plays a vital role in India’s development and it contributes about 8-10 per cent to GDP on an average. Developing nations like India need to have faster construction with high quality, durability and a pollution-free environment, which can be achieved only with Ready mix concrete (RMC). The usage of GGBS is very high in RMC industry. Compressive strength and workability are the most important and basic properties of concrete for any applications. An experimental investigation is carried out on optimum usage of GGBS in Ready Mix concrete industry. This paper presents the experimental test results of 27 types of concrete mixes made with 10% to 80% replacement of ordinary Portland cement. Slump retention for 180 minute which is a basic requirement for an RMC industry is carried out. Compressive strength testing of all the specimens was carried out at 7, 28, 56, 90 and 180 days. The test results proved that the compressive strength of concrete mix containing GGBS increases but after 50% of the total binder content, the addition of GGBS does not improve the strength of concrete. The reason could be GGBS may act as fine aggregate.

In today’s era the image has become useful for communication purpose. But due to the development of software and various techniques it is possible to change images in adding or removing essential feature from it without leaving a clue of real image. It is not easy for the common people to identify whether the image original or tampered. In order to avoid this problem, forgery detection came into existence. Detection of forgery refers to task of image processing to identify that the images are unique or tampered. Several techniques have been used in order to detect the forgeries from the forged image, but this issue has not yet solved. In order to solve these issues we have used Discrete Cosine Transformation (DCT) and quantization matrix techniques for identifying forged areas of image, where the quality of image is not reduced. The Discrete Cosine Transformation (DCT) is used in order for characterizing the overlapping blocks and quantization matrix is used to compress DCT values and gives both highly compressed and best decompressed image quality. Here we use block matching algorithm. This algorithm one of the most frequently used for detecting image which is duplicate. This proposed work also supports for different kinds of images such as JPEG, JPG or PNG of any size it can be either mxn or nxn.

The article is dedicated to analyzing technical and legal means of concluding an agreement via the Internet. During their study, the authors have determined that there are two main ways to conclude these contracts: to conclude contracts by exchanging e-documents and to carry out implicative actions, each of which has its own characteristics. The correlation and analysis of civil legal relations and judicial practice have shown the possibility of both ways that can sometimes corroborate and replace each other. The authors have come to the conclusion that today a click-wrap agreement widely used when providing the access to content or services on the Internet is of particular popularity among users of Internet resources. At the end, the authors have drawn the conclusion that it is necessary to reduce the excessive impact of the state on the economy in the area of digital relations by creating public means of control, such as self-regulation. This can be achieved by providing such organizations with broad rights and powers, and at the same time establishing high responsibility for violating the law.

This Paper enlightens the significance of the reliability evaluation for an electrical power distribution network using the analytical technique FMEA. The power distribution system is subject to interruptions frequently as a lot of devices are responsible for its effective operation. All the possible failures of each component are considered and the reliability is evaluated in terms of system reliability indices like SAIFI, SAIDI, ENS, and ASAI. FMEA method observes the failure modes of a procedure and reduces it by ranking over its impacts. In this paper, RBTS bus2 distribution network is used for the analysis. The influences of various feeder reconfigurations are considered and the system reliability indices are obtained. The obtained results show that the reliability of the distribution system is enriched with various feeder reconfigurations. Reliability Evaluation helps to design the future Distribution system and its expansion.
