Academic literature on the topic 'Cvlib'

Sketch based image retrieval (SBIR) is a sub-domain of Content Based Image Retrieval(CBIR) where the user provides a drawing as an input to obtain i.e retrieve images relevant to the drawing given. The main challenge in SBIR is the subjectivity of the drawings drawn by the user as it entirely relies on the user's ability to express information in hand-drawn form. Since many of the SBIR models created aim at using singular input sketch and retrieving photos based on the given single sketch input, our project aims to enable detection and extraction of multiple sketches given together as a single input sketch image. The features are extracted from individual sketches obtained using deep learning architectures such as VGG16 , and classified to its type based on supervised machine learning using Support Vector Machines. Based on the class obtained, photos are retrieved from the database using an opencv library, CVLib , which finds the objects present in a photo image. From the number of components obtained in each photo, a ranking function is performed to rank the retrieved photos, which are then displayed to the user starting from the highest order of ranking up to the least. The system consisting of VGG16 and SVM provides 89% accuracy

Considerando o crescimento significativo dos Crimes Violentos Letais e Intencionais (CVLI) e buscando elementos que colaboram com esse aumento, este estudo tem como objetivo analisar os principais fatores que influenciam o crescimento desses crimes, levando em consideração condições sociais, econômicas e políticas. As análises foram voltadas para o Estado de Pernambuco, mais especificamente à Região Metropolitana do Recife e à cidade de Caruaru, no interior do Estado, com dados coletados contidos nas bases de dados secundários da Gerência de Análise Criminal e Estatística (Gace) e da Agência Estadual de Planejamento e Pesquisas de Pernambuco – Condepe/Fidem. Por fim, os resultados mostram que as circunstâncias econômicas do país, que atingem diretamente as políticas públicas e a condição social da população, corroboram o crescimento desses crimes, uma vez que é possível perceber que nos picos de crise econômica é onde tambem ocorrem os picos de criminalidade.

A violência e a criminalidade nas periferias de Belém-PA apresentam forte relação com a precariedade socioespacial. O objetivo da pesquisa consiste em analisar as diferenciações socioespaciais no bairro da Terra Firme, em Belém do Pará, e suas implicações na ocorrência dos Crimes Violentos, Letais e Intencionais – CVLI e na produção de (in)justiças espaciais. A partir de levantamentos bibliográficos, análises documentais e trabalhos de campo constatou-se que a desigualdade socioespacial é marcante no bairro, assinalada pelos aglomerados subnormais, cotas de altimetria e proximidades com instituições públicas. Ademais, destacam-se a violência e a criminalidade através dos CVLI como expressões de outras precariedades e um fator de reforço a elas.

Este estudo discute as implicações dos crimes violentos letais e intencionais - CVLI no desenvolvimento regional, crimes que afetam a qualidade de vida e o bem-estar social, bem como o desenvolvimento socioeconômico. Utilizamos artigos publicados nos últimos anos, que atenderam os critérios de inclusão e exclusão, onde foram selecionados 25 trabalhos que atenderam os critérios pré-estabelecidos, sendo assim, avaliados e analisados, contribuindo deste modo para a produção desta revisão. Identificamos fatores, que estão associados ao aumento e redução dos CVLI e suas consequências no desenvolvimento regional. As descobertas indicam que melhores oportunidades na educação, emprego com salários dignos, renda, mobilização da sociedade civil, políticas de estado mais rígidas, são aspectos capazes de reduzir crimes violentos letais intencionais.

Variable ventilation (VV), characterized by breath-to-breath variation of tidal volume (Vt) and breathing rate (f), has been shown to improve lung mechanics and blood oxygenation during acute lung injury in many species compared with conventional ventilation (CV), characterized by constant Vt and f. During CV as well as VV, the lungs of mice tend to collapse over time; therefore, the goal of this study was to develop a new VV mode (VVN) with an optimized distribution of Vt to maximize recruitment. Groups of normal and HCl-injured mice were subjected to 1 h of CV, original VV (VVO), CV with periodic large breaths (CVLB), and VVN, and the effects of ventilation modes on respiratory mechanics, airway pressure, blood oxygenation, and IL-1β were assessed. During CV and VVO, normal and injured mice showed regional lung collapse with increased airway pressures and poor oxygenation. CVLB and VVN resulted in a stable dynamic equilibrium with significantly improved respiratory mechanics and oxygenation. Nevertheless, VVN provided a consistently better physiological response. In injured mice, VVO and VVN, but not CVLB, were able to reduce the IL-1β-related inflammatory response compared with CV. In conclusion, our results suggest that application of higher Vt values than the single Vt currently used in clinical situations helps stabilize lung function. In addition, variable stretch patterns delivered to the lung by VV can reduce the progression of lung injury due to ventilation in injured mice.

1. The cerebral ventral 1 (CV1) interneurones of Lymnaea occurred as a population of at least three in each ganglion, all with similar morphologies. Steady depolarization of a CV1 cell led to initiation and maintenance of rhythmic feeding motor output from the buccal ganglia. 2. CV1 interneurones produced facilitating excitatory postsynaptic potentials in Nl interneurones of the buccal central pattern generator for feeding. Connections with N2 interneurones were not found. 3. The CV1 population could be separated into two subgroups. CVla received strong synaptic feedback in phase with the buccal rhythm, leading to strong bursting during generation of feeding motor output. CVlb received only weak feedback, and often fired continuously when depolarized. 4. Unitary inhibitory postsynaptic potentials were characteristic of all CV1 neurones, but were only visible in CVlb when it was depolarized. These inputs are thought to arise indirectly from the buccal central pattern generator. 5. The CV1 population is probably homologous with similar neurones in other gastropod species.

Quando se trata da segurança pública no atual momento vivido pelo Brasil, com altos índices de criminalidade e escassez de recursos, avaliar o desempenho das políticas públicas é de vital importância. No geral, os resultados das políticas e ações de segurança pública estão sendo avaliados através da comparação das variações periódicas de indicadores baseados nas quantidades de ocorrências de tipos de delitos. Esta pesquisa parte da premissa de que para avaliar a eficiência de uma política pública não é suficiente comparar valores de indicadores sem considerar mudanças no contexto e a significância da variação. Foram utilizados os dados sobre Crime Violento Letal Intencional – CVLI, correspondentes aos anos de 2014, 2015, 2016 e parte de 2017, disponibilizados na página na internet da Secretária da Segurança Pública do Estado da Bahia, para comparar os resultados em segurança pública no Município de Salvador, Capital do Estado da Bahia, mediante testes estatísticos, análise de série temporal e o uso de técnicas de controle estatístico de processo – CEP. Restou a conclusão de que, mesmo com as variações negativas nas conjunturas econômicas e sociais no território, o indicador de desempenho, no que tange ao CVLI, manteve um desempenho constante, não ocorrendo piora e nem melhora.

This paper presents an optimization algorithm for tuning the interpolation parameters of computer numerical control (CNC) controllers; it operates by considering multiple objective functions, namely, contour errors, the machining time (MT), and vibrations. The position commands, position errors, and vibration signals from 1024 experiments were considered in the designed trajectory. The experimental data—the maximum contour error (MCoE), MT, and corner vibration (CVib)—were analyzed to compute the performance index. A backpropagation neural network (BPNN) with 20 hidden layers was applied to predict the performance index. The correlation coefficients for the predicted values and experimental results for the MCoE, MT, and CVib based on the validation data were 0.9984, 0.9998, and 0.9354, respectively. The high correlation coefficients highlight the accuracy of the model for designing the interpolation parameter. After the BPNN model was developed, a genetic algorithm (GA) was adopted to determine the optimized parameters of the interpolation under different weighting of the performance index. A weighted sum approach involving the objective function was employed to determine the optimized interpolation parameters in the GA. Thus, operators can judge the feasibility of the interpolation parameter for various weighting settings. Finally, a mixed path was selected to verify the proposed algorithm.

Currently, in conditions of distance learning of students, the problem of the organization of practical and laboratory works acquires special importance. This mainly applies to technical universities, where training in normal conditions is carried out on real equipment and using specialized software. As a result, there is an urgent need to create virtual labs as an effective platform for distance learning for students, particularly in the field of cybersecurity. In this case, one of the effective solutions is to create and deploy a Cybersecurity Virtual Laboratory (CVLab) for distance learning, which will help ensure continuous quality training of future professionals. Besides, distance learning must not be for informational purposes only. Therefore, the formation of practical skills of students requires rapid development and implementation of the effective means of distance learning. Recently, the trend of virtualization of both networks and computers has developed intensively, which allows the development and implementation of more flexible types of virtualized laboratory solutions, including for distance learning. The number of virtualization tools, as well as the latest network equipment created to work in a virtual environment (hypervisors) is increasing. Thus, virtualization allows us to overcome the limitations of traditional networks and hardware network laboratories, given their high cost, power consumption, stability, a limited number of devices, and so on. The introduction of the virtual cybersecurity laboratory CVLab in order to increase the effectiveness of distance education meets the objectives of the Cybersecurity Strategy of Ukraine, as well as priorities and areas of its provision, ranging from general digital literacy to training of security sector actors.

The present work deals with the issue of violence in the state of Bahia, specifically in the municipality of Cruz das Almas-BA. This study has as main objective the spatiotemporal analysis of the occurrences of Intentional Lethal Violent Crimes (CVLI), in the municipality of Cruz das Almas-BA, registered between the years of 2010 and 2015, through geoprocessing techniques, identifying the most criticism in the municipality. The qualitative and quantitative research methodology consisted in the development of the work in three stages: theoretical-conceptual approach related to definitions, manifestations, possible determinants of violence and the use of geotechnologies in criminal mapping; presentation of the main National Plans of Public Security implanted in Brazil from the first FHC government and the role of municipalities and municipal guard, from the Federal Constitution of 1988, in facing the problems in the area of public security; collection of official data of the population in the IBGE, technical visits in institutions located in the municipality of Cruz das Almas, as Territorial Delegation and Planning Secretariat, and data collection in the portal of the Secretariat of Public Security of the state of Bahia and the Brazilian Forum of Security Of murder, robbery and bodily injury followed by death. The main results are the lack of an effective National Public Safety Plan that puts into practice the reduction of crime in the country, the absence of the State and the lack of joint participation with municipalities in the performance of public safety. It is noted that some municipalities create their own strategies through punctual actions in controlling crime. In Cruz das Almas, the increase in violent crimes is seen as another municipality in the interior that has high rates. Several actions are being carried out in the area of public safety by the police with collaboration of the municipality and there is a reduction in the CVLI indexes in the following years (2016-2017) to the studied period.
O presente trabalho tem como tem?tica a quest?o da viol?ncia no estado da Bahia, especificamente no munic?pio de Cruz das Almas-BA. Esse estudo tem como principal objetivo a an?lise espa?o-temporal das ocorr?ncias dos Crimes Violentos Letais Intencionais (CVLI), no munic?pio de Cruz das Almas-BA, registrados entre os anos de 2010 e 2015, atrav?s de t?cnicas de geoprocessamento, identificando as ?reas mais cr?ticas no munic?pio. A metodologia da pesquisa, de car?ter qualitativo e quantitativo, consistiu no desenvolvimento do trabalho em tr?s etapas: abordagem te?rico-conceitual relacionada as defini??es, manifesta??es, poss?veis determinantes da viol?ncia e a utiliza??o das geotecnologias no mapeamento criminal; apresenta??o dos principais Planos Nacionais de Seguran?a P?blica implantados no Brasil a partir do primeiro governo FHC e o papel dos munic?pios e da guarda municipal, a partir da Constitui??o Federal de 1988, no enfrentamento dos problemas na ?rea de seguran?a p?blica; coleta de dados oficiais da popula??o no IBGE, visitas t?cnicas em institui??es localizadas no munic?pio de Cruz das Almas, como Delegacia Territorial e Secretaria de Planejamento, e coleta de dados no portal da Secretaria de Seguran?a P?blica do estado da Bahia e do F?rum Brasileiro de Seguran?a P?blica dos homic?dios dolosos, latroc?nio e les?o corporal seguida de morte. Como principais resultados, constata-se a falta de um Plano Nacional de Seguran?a P?blica eficaz que coloque em pr?tica a redu??o da criminalidade no pa?s, a aus?ncia do Estado e a falta de participa??o conjunta com os munic?pios na atua??o da seguran?a p?blica. Nota-se que alguns munic?pios criam suas pr?prias estrat?gias atrav?s de a??es pontuais no controle ? criminalidade. Em Cruz das Almas, o aumento dos crimes violentos ? constatado como mais um munic?pio do interior que possui ?ndices elevados. V?rias a??es est?o sendo realizadas na ?rea da seguran?a p?blica por parte da pol?cia com colabora??o do munic?pio e constata-se redu??o nos ?ndices de CVLI nos anos seguintes (2016-2017) ao per?odo estudado.
