Authors:   Institute of Automation and Electrometry SB RAS, Bessmeltsev V. , Bulushev E. ,   Institute of Automation and Electrometry SB RAS
Published: September 2016

We investigated the possibility of fast quality control of laser micromachining of surface based on optical measurements. The main objective is to match CAD-model and 3D geometry of the machined surface. We found that standard matching algorithms have either low performance or are ineffective at high noise level or at presence of geometrical distortion. The algorithm based on Ciratefi algorithm, which previously wasn’t used for image registration, was developed. The performance of algorithm was increased by using an iterative search of optimum based on image pyramid. The testing of algorithm on height maps of objects formed by laser methods showed its high accuracy and performance.

We study deals with the transformation of a uniformly polarized Bessel beam in a crystal of Iceland spar in nonparaxial regime. The polarization transformations taking place in the crystal are numerically and experimentally investigated. It is shown that these transformations provide the interaction of ordinary and extraordinary beams, which becomes significant only in the nonparaxial regime.

Authors:   Samara State Aerospace University, Zavershinskiy D. ,   P.N. Lebedev Physical Institute of RAS, Samara Branch, Molevich N. ,   Samara State Aerospace University,   P.N. Lebedev Physical Institute of RAS, Samara Branch
Published: September 2016

Earlier, we demonstrated the possibility of energy transfer from unstable acoustic waves into Alfven waves due to a process of three-wave interaction of collinear waves. In this paper, we briefly discuss cooling mechanisms and possible heating scenarios of an optically thin plasma medium. The upper layers of the solar atmosphere have been chosen as the model medium. By the use of two cooling function models we obtain temperature intervals in which the instability can take place and calculate acoustic increments for all heating scenarios.

Authors:   Samara State Aerospace University, Bezus E. ,   P.N. Lebedev Physical Institute of RAS, Samara Branch, Doskolovich L. ,   Samara State Aerospace University,   P.N. Lebedev Physical Institute of RAS, Samara Branch
Published: September 2016

It is shown theoretically and numerically that a planar structure consisting of two dielectric layers made of isotropic materials can be used to decrease surface plasmon polariton parasitic scattering an arbitrary incidence angle. Average scattering losses decrease by an order of magnitude down to 0.015. Phase modulation and refraction of surface plasmon polaritons with the scattering suppression are well described by an analytical model based on the Fresnel equations. The proposed approach can be used for the design of plasmonic lenses, reflectors, plasmonic crystals and resonators of plasmonic lasers.

Authors:   Samara State Aerospace University, Savelyev D. ,   Image Processing Systems Institute, Russian Academy of Sciences, Khonina S. ,   Samara State Aerospace University,   Image Processing Systems Institute, Russian Academy of Sciences
Published: September 2016

The analysis of the impact of variations in the size of a silicon micro-cylinder with a subwavelength radius on the diffraction of circularly polarized Gaussian beams was performed using a finite-difference time-domain (FDTD) method. It is numerically shown that a Gaussian beam can be focused near the surface of the element in a light spot, whose size at full-width at half-maximum of the intensity is 0.25λ. It is demonstrated that the silicon cylinder illuminated by a laser beam with a vortex phase singularity of the first order forms a light spot, with its central part mainly formed by the longitudinal component of the electric field. (FWHM = 0.29λ).

Published: September 2016

With use of a liquid crystal phase-only spatial light modulator, we generate form-invariant Half-Pearcey laser beams (HP-beams), which were recently proposed by the present authors [Computer Optics, v. 38, no. 2 (2014)]. It is experimentally shown that upon propagation the HP-beams preserve their shape up to a scale and rotate by 180 degrees. These beams have the ability to auto-focus and reconstruct their intensity pattern after partial distortion by an amplitude defect (property of self-healing). The amplitude and phase of the HP-beam were encoded with the modified two-phase algorithm. Ignoring the amplitude and using only the phase leads to greater distortions of the HP-beam comparing with the two-phase encoding algorithm.
Calculation of diffraction of laser radiation by a two-dimensional (cylindrical) axicon with the high numerical aperture in various models
Authors:   Image Processing Systems Institute, Russian Academy of Sciences, Khonina S. ,   Samara State Aerospace University, Ustinov A. ,   Image Processing Systems Institute, Russian Academy of Sciences,   Samara State Aerospace University, Degtyarev S. ,   Image Processing Systems Institute, Russian Academy of Sciences,   Samara State Aerospace University
Published: September 2016

We consider the diffraction of Gaussian beams by a cylindrical axicon whose numerical aperture (NA) is close to or higher than a limiting value (when the incident wave is assumed not to pass through an element). Three models of diffraction were considered: the ray approach, the vector wave theory with a thin optical element approximation and the solution of Maxwell’s equations by the finite elements method. Although in the ray approach the limiting NA corresponds to the total internal reflection (TIR), the analysis of the ray path has shown that with increasing NA (narrowing axicon’s angle) a proportion of energy leaks through the lateral sides, forming a diverging beam. In the wave theory, energy dissipation in lateral directions also occurs, but evanescent waves play a special role in the element’s near-field zone. In this case, the analytical estimations for the electric field components have been obtained in a thin element approximation. Application of the finite element method to Maxwell’s equations has shown that for optimal concentration of energy at the refractive element’s tip its NA should be increased (by narrowing the axicon’s angle or by increasing the material refractive index) only until the TIR occurs. The further increase of the NA results in both the reflection of rays from the flat surface and their output from the lateral sides.

Combined holographic optical elements for optical systems of multicolor character/symbol display devices are described. This element combines the functions of four-level diffractive optical elements with high diffraction efficiency and spectral plasmon filters with a variable bandwidth depending on the incidence angle. The theoretical studies suggest the feasibility of combining the two types of elements in a single structure.

We demonstrate optical trapping and movement of a carbon nanoparticle agglomeration with both a single optical bottle beam and arrays of such traps. Diffractive optical elements (DOE) designed by a method based on a superposition of the Bessel beams were employed for the generation of the optical traps. Due to the structure of the generated traps, we were able to carry out a three-dimensional movement of trapped microscopic objects.

Authors:   Ufa State Aviation Technical University, Kutluyarov R. , Sultanov A. ,   Ufa State Aviation Technical University, Bagmanov V. ,   Ufa State Aviation Technical University
Published: September 2016

We consider interaction of polarization-mode dispersion (PMD), Kerr-nonlinearities and chromatic dispersion and its effect on the quality of WDM-transmission in a fiber link. We simulate the propagation of RZ- and NRZ-coded signals in a multispan link with optical amplification and chromatic dispersion compensation. For some fiber realizations signal impairments reduction occurs in the case of PMD and nonlinearities interaction as compared to the case of nonlinear transmission with no PMD. This signal enhancement is related to the pulse compression and this phenomenon is determined by the frequency dependence of PMD.

Published: September 2016

We propose a new analytical method for the calculation of an optical element that forms the intensity distribution in compliance with the requirements for automotive-beam headlamps. The optical element consists of a collimator, operating on the principle of total internal reflection (TIR), and a microlens array, creating the required intensity distribution. As an example, an optical element producing the headlight beam of classes B, C, D is presented. With an optical element of size 33 × 23 mm, it is enough to use two modules to generate a headlight beam of classes B, C and three modules for a headlight beam of class D.

We discuss the simulation of a hyperspectrometer based on the use of linear variable filters. The possibility of recovery of the image spectral pixels through the solution of the integral equation is considered. Estimates of the scattering spot size as a function of the spectral filter parameters are obtained. The numerical results show that a significant deterioration in resolution occurs only in the case of short-focus optical systems.

In this article, a novel linear spectral unmixing algorithm is proposed and analyzed. The linear spectral mixture defines a model of pixels for hyperspectral images by means of spectral signatures. A set of spectral signatures is assumed to be known. Constraints are imposed on the spectral mixture coefficients: the sum of the coefficients is equal to unity and each coefficient is nonnegative. The results of the algorithm quality and speed analysis are described in the paper.

Authors:   Samara State Aerospace University, Myasnikov E. ,   Image Processing Systems Institute, Russian Academy of Sciences
Published: September 2016

This paper considers two approaches to the hierarchical decomposition of the feature space to improve the efficiency of the non-linear dimensionality reduction method. The first approach suggested by the author of the paper is based on the decomposition of the original feature space using hierarchical clustering. The second original approach is based on a hierarchical decomposition of the target space by using a KD-Tree. The approaches analyzed are evaluated in terms of the efficiency of the non-linear dimensionality reduction method.

The possibility of application of different textural features for the lung disease automatic diagnosis on the basis of the 2D digital computed tomography (CT) images was studied. Histogram features, covariance features, Haralick’s features and run length features were used. A procedure based on the discriminant analysis criterion was used for the selection of the best features group. We experimentally showed that the approach offered is convenient to use for solving the problem of automatic diagnosis on a 160-image set received during examination of patients with a chronic obstructive pulmonary disease. The resulting group of effective features includes two Haralick’s features and three run length features, providing the error rate of 0.11, which is better than similar results obtained without a feature selection procedure.

Authors:   Bauman Moscow State Technical University, Vasil’ev N. , Morozov A. ,   Bauman Moscow State Technical University
Published: September 2016

Substance identification by their luminescence spectra is a highly sensitive and non distraction method. If a signal level is low then recognition errors may occur. The aim of this work was to define the identification algorithm with error probability control. For this purpose, the value of dissimilarity measure in the form of Spectral Angle Mapper (SAM) was analyzed. The relation between errors in measured spectra and the dissimilarity measure distribution was defined. The accuracy of the statistical hypothesis was used in spectral library search. The resulting algorithm was tested on more than 4000 sample spectra. The case when the measured spectra contained a signal of unknown source was analyzed, as well as the case when the measured spectra might contain either a signal or be equal to noise.

Published: September 2016

We propose a method of polarization-based measurement of thickness and birefringence of uniaxial crystal X-cuts, which consists in measuring the spectral transmittance of a "polarizer-crystal-analyzer" structure. With use of X-cuts of a congruent lithium niobate with a nominal thickness of 1.052 mm, the validity of the method is experimentally confirmed and recommendations on its practical use are made. A possibility to control the Bessel beam conversion in CaCO3 crystal via changing its thickness is shown. The controlled conversion of a zero-order Bessel beam into a second-order vortex Bessel beam due to effect of the thermal linear expansion of a crystal by heating is experimentally investigated.

An asymptotic behavior of orbital angular momentum (OAM) for the light field as superposition of Hermite-Gaussian modes is considered. An analytical formula for the OAM of such fields is obtained. For a three- and four mode superposition it was found that their OAM can be larger than the maximum index in the superposition while the structural stability of the light field is retained.
Matched polynomial features for the analysis of grayscale biomedical images
Authors:   Samara State Aerospace University, Gaidel A.
Published: September 2016

We considered the general form of polynomial features represented as polynomials in the image pixels domain. We showed that under natural constraints these polynomial features turned to linear combinations of the image autocovariance function readings. We proposed a number of approaches for matching the features under study with texture properties of images from a training sample. During computational experiments on three sets of real diagnostic images we demonstrated the efficiency of the proposed features, which involved the decrease of the recognition error probability of X-ray bone tissue images from 0.10 down to 0.06 in comparison with the previously studied methods.

Authors:   Tomsk Polytechnic University, Spitsyn V. , Bolotova Yu. ,   Tomsk Polytechnic University, Phan N. ,   Ba Ria-Vung Tau University, Bui T. ,   Ba Ria-Vung Tau University
Published: September 2016

In this paper we propose a novel algorithm for optical character recognition in the presence of impulse noise by applying a wavelet transform, principal component analysis, and neural networks. In the proposed algorithm, the Haar wavelet transform is used for low frequency components allocation, noise elimination and feature extraction. The principal component analysis is used to reduce the dimension of the extracted features. We use a set of different multi-layer neural networks as classifiers for each character; the inputs are represented by a reduced set of features. One of the key features of the proposed approach is creating a separate neural network for each type of character. The experimental results show that the proposed algorithm can effectively recognize the characters in images in the presence of impulse noise; the results are comparable with ABBYY FineReader and Tesseract OCR.

Methods for assessing the quality of image superimposition, which include the local and integral estimates of the superimposition quality, are proposed.

Published: September 2016

A new optical surface reconstruction technique in the source-target mapping method is proposed. The technique is based on the representation of the surface as an envelope of a parametric family of paraboloids (ellipsoids). Using such a representation, the calculation of the optical surface is reduced to solving a complete differential equation without regard for the coordinate system. By way of illustration, mirrors that generate uniform intensity distributions in a square region are designed. Simulation of the design examples shows high performance of the proposed technique: it allows us to obtain good-quality intensity distributions even with violation of the integrability condition.

Published: September 2016

We proposed a method of the formation of structures in materials by laser treatment aimed to enhance the performance characteristics of aircraft engine parts. The experimental study was conducted using a high-power gas CO2 laser ROFIN DC 010. Using an optical system comprising a focusing diffractive optical element, the laser beam was focused into a focal line with the maximum power density in its center. Tests on the joint deformation of the coating and substrate were conducted. We also determined the running-in ability of the ANB + NA-67 coating following the cut-in of an opposite element. It was found that the laser treatment of the sublayer enabled the bending angle to be increased while avoiding cracking and delamination of the coating.

Authors: Sadeghnia Hamid , Cortez Miguel , Liu Dick , Hosseinzadeh Hossein , Snead O. Carter
Published: September 2016

PURPOSE: We examined the effect of safranal, a constituent of Crocus sativus, in acute experimental animal models of generalized absence seizures. METHODS: We further characterized its effects on the GABAergic system through the regional modification of [3H] flunitrazepam, a benzodiazepine agonist binding site and [3H] CGP54626A, a GABAB receptor antagonist binding site in mouse brain. RESULTS: The systemic administration of safranal resulted in a significant and dose-dependent attenuation in experimental absence seizures elicited by either ?-butyrolactone (GBL), baclofen (BAC) or low doses of GABAA receptor antagonists; pentylenetetrazole (PTZ), picrotoxin (PTX) and bicuculline (BMC). After a single intraperitoneal administration of safranal (291 mg/kg), no changes in baseline electrocorticographic (ECoG) recording were observed, however, a significant decrease in [3H] flunitrazepam binding was seen in the cortex (33.16%, p<0.001), hippocampus (27.36%, p<0.01) and thalamus (29.91%, p<0.01) of mouse brain, while the [3H] CGP54626A binding did not show any modification in the same brain regions. CONCLUSION: These data indicate that there is an antiabsence seizure property in safranal and its effect may be due to modifications on the benzodiazepine binding sites of the GABAA receptor complex.

Published: September 2016

Artigo originário de pesquisa, cujo objetivo é perceber dinâmicas deliberativas concernentes às matérias de recursos e orçamentos públicos em conselho gestor de políticas públicas, visa perscrutar sobre seus efeitos no processo democrático. Constata que existem esforços do MDS voltados à transparência pública, mas no caso da política de assistência social o controle é dificultado devido à fragilidade de conhecimento dos conselheiros sobre uso de recursos e orçamento público, e em razão de estratégias políticas nem sempre comprometidas com a transparência e o cumprimentodos direitos sociais. Ressalta que um dos maiores desafios a ser enfrentado é a socialização desse conhecimento para osconselheiros que carecem dele. Conclui que os conselhos gestores podem ser tanto instrumentos de controle de tensõesentre democracia e capitalismo, como instâncias fortalecedoras de experiências renovadas voltadas à instituição de modelos de democracia participativa capazes de interagir com as instâncias representativas, fortalecendo o processodemocrático.Palavras-chave: Democracia participativa; políticas públicas; conselhos gestores; orçamentos públicos; controle socialPARTICIPATIVE DEMOCRACY, MANAGERS COUNCILS OF PUBLIC POLICIES AND SOCIAL CONTROL: budget andpublic resources in a deliberative stageAbstract: The article originated from research which objective is to perceive deliberated politics dynamics regarding resources and public budgeting in manager council of public policies, in order to verify its effects in the democratic process. It concludes that there are efforts from MDS directed to "public transparence" however concerning social assistance politics thecontrol is hampered due to the counselors' fragile knowledge towards the use of resources and public budget, and in the matter of politics strategies are not always engaged to the transparence and fulfillment of social rights. One of the biggestchallenges to be confronted would be the socialization of this knowledge to the counselors who need them. Concludes that the manager counselors can be as much as a sort of tension control instrument between capitalism and democracy as empowering instances of renewed experiences pointed to institute participative democracy models capable of interact within representative instances empowering the instances of the democratic process.Keywords: Participative democracy, public policies, managers councils, public budget, social control.

Published: September 2016

Este artigo traz uma reflexão sobre as políticas públicas do Estado brasileiro para as mulheres, mais precisamente, o Projeto Mulheres da Paz, política pública do Programa Nacional de Segurança com Cidadania – PRONASCI, do Ministério da Justiça, a partir de nossa experiência como facilitadoras das oficinas de capacitação promovidas pela Secretaria de Desenvolvimento Social e Combate à Pobreza - SEDES em parceria com a ONG Avante, para 48 mulheres residentes no Bairro de São Cristóvão, em Salvador/BA. Conclui que, ao concentrar esforços para que as mulheres atuem como mediadoras em zonas de conflito, através do desempenho de atividades calcadas nos papéis tradicionais de cuidado e educação dos jovens, que histórica e socialmente são designados às mulheres, o projeto, embora contribua para a melhoria das suas condições de vida, não potencializa o seu empoderamento e autonomia.Palavras-chave: Políticas públicas; Mulheres da Paz; gênero; mediação de conflitosPROJECT WOMEN OF PEACE: an aim of genderAbstract: This article, brings reflection on the Brazilian government public policies for women, more precisely, the Project Women for Peace, a public policy of the National Program for Public Security with Citizenship - PRONASCI, of the Ministry of Justice, from our experience as facilitators of the training workshops sponsored by the Department of Social Development and Fight Against Poverty - SEATS in partnership with the NGO AVANTE, to 48 women living in the neighborhood of São Cristovão, in Salvador / BA. It concludes that, by concentrating efforts for women to act as mediators in conflict zones, through the performance of activities based in traditional roles of care and education of young people, who are historically and socially assigned to women, the project, while contributing to the improvement of their living conditions, not enhances their empowerment and autonomy.Keywords: Public policies, Women for peace, gender, conflict mediation.

Authors: Viana Nelson Corrêa
Published: September 2016

O artigo analisa os modelos impostos por intelectuais orgânicos às economias periféricas, modelando-as para atender o grande capital. Explora e critica os desafios sobre esses modelos orçamentários ideais praticados em busca da transparência que mais afasta o interessado enquanto entroniza o tecnicismo, servo da política, nas montagens dos grandes números. Transparecer no orçamento é legitimar transferências públicas para o privado. Ao final, conclui com ceticismo sobre novas possibilidades para as políticas públicas pelas vias do orçamento sob o capitalismo neoliberal.Palavras-chave: Orçamento público; neoliberalismo; planejamento; transparênciaPUBLIC BUDGET: models, challenges and critic.Abstract: The article analyzes the models imposed by organic intellectuals to peripheral economies, shaping them to meetthe large capital.

O presente trabalho tem como objetivo entender a Economia do Crime, um tema muito pertinente nos dias de hojenos estados brasileiros. A partir de levantamento teórico e testes empíricos, verifica a hipótese de que a taxa de homicídios estápositivamente relacionada com o nível de desigualdade de renda e negativamente com o nível de educação, despesa com segurançae renda. Mostra que o teste foi realizado para todos os estados brasileiros, exceto Distrito Federal, no período de nove anos, entreos anos 2001 e 2009. Apresenta uma metodologia que está baseada no modelo econométrico em dados em painel com efeitos fixose efeitos aleatórios, ressaltando que o estimador usado no modelo foi o Mínimo Quadrado Ordinários (MQO). Indica, ainda, que o resultado encontrado foi que o modelo de efeitos fixos apresentou estatística mais significativa, porém o modelo de efeitos aleatórios apresentou o sinal esperado em seu coeficiente em 50% das variáveis explicativas. Por fim, aponta que o teste de Hausman provouque o modelo de efeito aleatório é melhor para explicar a hipótese.Palavras-chave: Crime, despesa com segurança, dados em painel.INCOME INEQUALITY AND EDUCATION CAN EXPLAIN CRIMINALITY? an analysis for the Brazilian statesAbstract: This study aims to understand the Economics of Crime, an issue very relevant today in Brazilian states. From theoretical and empirical research and test, it will analyze the hypothesis that the homicide rate is positively related to the level of income inequalityand negatively with the level of education, expenses with security and income. The test will be conducted for all states, except the Federal District, in the nine years between 2001 and 2009. The methodology is based on the econometric model on panel data withfixed effects and random effects estimator which model was used in the Ordinary Minimum Square (OLS). As the result has found that the fixed effects model showed the most meaningful statistics, the random effects model showed the expected sign on its coefficientin 50 % of the explanatory variables, while the Hausman test proved that the random effect model is better to explain the hypothesis.Key words: Crime, safety expenses, panel data.
