City vulnerability is an assessment of priorities for implementation in a city. Thus, it is imperative to determine vulnerable regions in the city to identify priority areas that may require immediate intervention. Several methods used for national, international and local level vulnerability assessment are based on remote sensing and GIS technology. This paper aims to determine the vulnerability of Hyderabad city using a geospatial based vulnerability index for sustainable development of the city. We use an urbanization and vulnerability concept for the development of city policy measures. We assessed the city vulnerability using a conceptual diagram composed of exposure, sensitivity and adaptive capacity. For Exposure, we considered the elevation (contour), watershed, waterway, roads, railways and airport thematic layers. For Sensitivity, the built-up area, industry, manages (?) system such as farmland and land use/cover map from GIS data were used. To examine the adaptive capacity, we addressed the natural vegetation layer, economic points and infrastructure. Results show that the center and northern part of the city are highly and extremely vulnerable due to industry and high socio-economic activities when compared with the southern part of the city. We divided the whole city into 5 types of vulnerability: Resilient 2.24 %, at risk 13.20 %, vulnerable 46.15 %, highly vulnerable 7.26 % and extremely vulnerable 31.15 % , in terms of the city area percentage. The vegetation area (50.51 %) has the maximum vulnerable area and the vulnerable class covers the maximum area (46.15 %) of the city. All this information is very indispensable and can be used to address management issues, such as resource prioritization and optimization.

In this article we numerically investigated tightly focusing an optical vortex with sector-wise azimuthal polarization by a Fresnel zone plate with numerical aperture NA = 0.95. The focal spot produced by a six-sector beam was shown practically not to differ from the focus produced by an ideal azimuthally polarized optical vortex, with the difference in the size of the focal spots not exceeding 0.001 of the wavelength of light.

The work is devoted to the problem of developing integrated single-photon sources based on spontaneous four-wave mixing in ring microresonators. Considering the silicon nitride microresonator as an example, we calculate the group velocity dispersion in a wide wavelength range for the case when the ring resonator is composed of straight and curved sections, and show that for different pump wavelengths it is possible to find an optimal ratio of the height and width of the waveguide, thereby achieving zero group velocity dispersion at a minimum height. Such waveguides, which provide zero dispersion and have a minimum height, are optimal for creating ring microresonators that generate single-photon states via non-degenerate spontaneous four-wave mixing.

An asymptotic method for calculating the complex amplitude of a light field in the case of diffraction by non-periodic band gap structures. The novelty of the approach consists in the expansion of the solution of the integral equation into a basis that describes the propagation of light through a DOE within the geometrical optics approximation and changes into a basis of plane waves used in the calculation of diffraction gratings. We present the results of focusing into a point by a gradient-index diffractive optical element with a band-gap structure. Simulation results confirm the efficiency of the proposed method.

In this work we propose a new approach to calculating the distribution of light fields in the framework of geometrical optics. A new integral operator for computing the intensity distribution in the geometrical optics approximation is suggested. Using the proposed method, we derive the intensity distributions of previously studied wavefronts. Singular points of these distributions are found and the intensity distributions near the caustics are calculated. The developed method is used to calculate the formation of caustics by harmonic diffractive optical elements in the axially symmetric case.

Authors:   Ulyanovsk State University (USU), Panyaev I. , Sannikov D. ,   Ulyanovsk State University (USU)
Published: December 2018

Spectral properties of surface TM-waves (polaritons) are considered in the guiding structure based on a narrow-band semiconductor (n-InSb) and a nanocomposite medium (layered metamaterial) in the mid-infrared region (5÷20 µm). The nanocomposite medium has a weak gyrotropy and contains layers of bismuth-doped iron garnet (BLIG, Lu3-xBixFe5-yGayO12) and gallium-gadolinium garnet (GGG, Gd3Ga5O12) layers magnetized to saturation. Solutions of the dispersion equations are investigated for the cases of linear and nonlinear response of the semiconductor. For an analytical description of the nonlinear response of the structure we use the «uniaxial» (longitudinal) and «biaxial» approximations. Dispersion spectra for the propagation constant, as well as field and energy characteristics of the surface polaritons are obtained and analyzed. Regions of the existence of soliton-like wave-fields of the surface polaritons are found for each of the description methods used. It is shown that the «uniaxial» model may be unsuitable for the calculation of the electromagnetic fields and energy flows in the structures based on cubic nonlinear media.

We discuss the results of calculating the spectral range boundaries for given diffraction orders of a thin focusing holographic optical element (HOE) with the corrected third-order spherical aberration. The variations of the spectral range boundaries are realized by varying the HOE characteristics such as shrinkage, diffraction order, recording wavelength, and the magnification factor at the recording wavelength.

Authors:   Volga State University of Telecommunications and Informatics, Glushchenko A. , Glushchenko E. ,   Volga State University of Telecommunications and Informatics
Published: December 2018

In the article we show in the geometric approximation the possibility of slowing down the light propagating along the axis of an optical waveguide structure by using metamaterials as optical structure elements. We study features of light propagation using a plane model of a fiber optic line whose cladding material has a negative refractive index. It is shown that by introducing a metamaterial, the propagation of light waves in the structure can be changed so that the light is decelerated along the structure axis to the extent that it stops, before starting to propagate in the opposite direction. We derive relationships for calculating the delay time as a function of geometrical and optical parameters of the structure, relationships for calculating critical parameters, and conditions for stopping the lighth.

The paper considers a problem of shape representation and classification. We propose a skeleton-geodesic histogram of thicknesses and distances for this purpose. It is based on the statistics of pair distances between shape elements. It is computed using skeleton-geodesic distances and thickness differences between pairs of skeleton edges. This differs from conventional geodesic histograms that are calculated for all figure points. The switch to the skeleton edges and areas of their attraction significantly speeds up the calculation of skeleton-geodesic histogram of thicknesses and distances, while maintaining many useful properties inherent in usual geodesic histograms. Extensive experimentation has been conducted on the most difficult binary shape database. Obtained classification results indicate the high potential of the proposed descriptor.

A method for counterfeit bill detection based on a digital image for mass-production smartphones is developed. The method under consideration does not require new protective elements to be designed and introduced into the print and is based on the use of digital image analysis and recognition methods, allowing one to carry out an automatic search and verification of known protective elements of the print. The peculiarity of the proposed approach is associated with constructing a feature vector for each type of samples and their subsequent classification using machine learning based on a training sample. The method is realized as a program application for smartphones, performing the automatic detection of an object in the frame, shooting the camera-captured object, rejection of unsuitable images, determination of a face-value and type of the banknote, and finally, verification of the authenticity.

This paper presents a new approach to constructing a biometric template using a Convolutional Neural Network (CNN) with Hashing Forest. The approach consists of several steps: training a convolutional neural network, transforming it to a multiple convolution architecture, and finally learning the output hashing transform via a new Boosted Hashing Forest technique. This technique generalizes the Boosted SSC (Similarity Sensitive Coding) approach for hashing learning with joint optimization of face verification and identification. The proposed network via hashing forest is trained on the CASIA-WebFace dataset and evaluated on the LFW dataset. The result of coding the output of a single CNN is 97% on LFW. For Hamming embedding, the proposed approach enables a 200 bit (25 byte) code to be constructed with a 96.3% verification accuracy and a 2000-bit code with a 98.14% verification accuracy on LFW. The convolutional network with hashing forest with 2000´7-bit hashing trees achieves 93% rank-1 on LFW relative to the basic convolutional network's 89.9% rank-1. The proposed approach generates templates at the rate of 40+ fps with a GPU Core i7 and 120+ fps with a GPU GeForce GTX 650.
Minimizing the entropy of post-interpolation residuals for image compression based on hierarchical grid interpolation
Authors:   Samara National Research University, Gashnikov M.
Published: December 2018

An adaptive parameterized interpolator for image compression based on hierarchical grid interpolation is developed and investigated. For optimizing the interpolator parameters an approach is proposed based on the minimization of the entropy of the quantized post-interpolation residuals, which is used as an estimate of the volume of compressed data. A recursive procedure for calculating the parameters of the developed interpolator is proposed, and theoretical estimates of its computational complexity are calculated. As part of a hierarchical image compression method, the developed interpolator is experimentally investigated, as well as making its comparison with averaging interpolators and an adaptive interpolator based on optimizing the sum of the absolute values of the interpolation errors. The developed interpolator is shown to have an advantage over the prototypes in terms of the compressed data size for various compression errors.

Authors: Zaki H. , Mahgoub H. , Abdalla B.
Published: December 2018

Background: Cigarette smoking is a leading preventable risk factor for the development and progression of cardiovascular diseases (CVDs). Epidemiologic studies in smokers confirm the association between the alteration in lipid profile levels and CVDs risk. Fibrinogen, an acute phase reactant with active involvement in endothelial function, thrombosis and inflammation. It is signified as a systemic marker of carotidatherosclerosis. The purpose of this study was to assess the level of fibrinogen and lipid parameters in Sudanese tobacco smokers.
Methods: This case-control study included 55 adult male of a current smoking status; their ages ranged between 18 and 54 years, and 100 non-smokers considered as controls. We evaluated the effect of cigarette smoking on plasma fibrinogen and serum lipid profile. The American Heart Association guidelines and reference ranges were used to identify the smokers with increased risk of coronary heart disease.
Results: Our study revealed an increase in the levels of fibrinogen, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) among smokers than controls, whereas the mean level of and triglycerides did not differ. The levels of highdensity lipoprotein cholesterol HDL-C demonstrated decrement. Further, smokers were classified according to the atherogenic risk index LDL-C/HDL-C ratio, the studied parameters fibrinogen, total cholesterol, and triglycerides were significantly increased in those who have ratio 4.5 and more (p = 0.001, p = 0.018, p = 0.007, respectively). Smokers with atherogenic index ≥ 4.5 were more likely to have ≥ 300 mg/dl fibrinogen level (odds ratio (OR) 3.96, 95% confidence interval (95%CI) 1.14– 13.73, p = 0.026). Moreover, the level of the fibrinogen can be predicted by linear regression equation: Fibrinogen level = 19.49 + 79.08 (the ratio of LDL-C ⁄HDL-C), r = 0.37, p = 0.008, 95%CI 21.20–136.95.
Conclusion: Increased fibrinogen, LDL-C, and LDLC/HDL-C ratio may potentiate the development of cardiovascular disease in smokers.

Published: December 2018

مقدمه: هپاتیت B بیماری سیستمیک است که موجب التهاب کبد می شود. راه مقابله با این عفونت، واکسیناسیون است. واکسن متداول برای مقابله، واکسن فرموله شده با Alum می‌باشد. این واکسن قادر به ایجاد پاسخ و مصونیت کامل در برخی افراد نیست. در این مطالعه پاسخ های ایمنی سلولی و هومورال واکسن تجاری هپاتیت B با واکسن HBs فرموله شده با ادجوانت MF59 مقایسه شد.
روش بررسی: در این مطالعه تجربی، موش‌های Balb/c در سه دوره، فرمولاسیون‌های مختلف واکسن را به صورت زیر پوستی و با فاصله دو هفته دریافت نمودند. سپس از موش‌ها خون گیری به عمل آمد و سطح آنتی‌بادی ضد HBs Ag با روش الایزا بررسی شد. سایتوکاین‌های IFN-γ،IL-4  و  IL-2و نسبت IL-4 IFN-γ/ا با روش الایزا از سوپ روئی کشت سلول های طحال بررسی شد. داده‌های خام با استفاده از نرم افزار Graph pad prism و آنالیز آماری با آزمون آماری ANOVA انجام شد.
نتایج: میزان IL-4 به طور معناداری در واکسن با آلوم بیشتر از واکسن فرموله شده با MF59 بوده هم چنین میزان سایتوکاین IFN-Y اختلاف معناداری را بین دو گروه اصلی نشان نداد. سایتوکاین TNF-α در واکسن با آلوم نسبت به واکسن با MF59 بیشتر ترشح شده است. آنتی‌بادی توتال پس از تزریق سوم در بعضی رقت‌ها در واکسن تجاری نسبت به واکسن با MF59 افزایش بیشتری داشت.
نتیجه‌گیری: کاهش معنادار IL-4 و آنتی بادی ها نشان می‌دهد که تمایل واکسن فرموله شده با MF59 برای القای پاسخ ایمنی سلولی نسبت به هومورال بیشتربوده به علاوه ایمن بودن و کمبود عوارض جانبی ادجوانت MF59 را نیز می‌توان مزیتی دیگر به شمار آورد

On the other hand, less common fauna included Gastropods, Pelecypods,
Echinodermata fragments, Algae, Ostracods and many of bioclasts, as well as
non-skeletal grains intraclasts and pisoids, while the ground mass mainly
compose of a micrite and micro-sparite. Several diagentic processes affected
the Jeribe formation which include mainly of dolomitization, cementation, micritization,
dissolution, compaction, fracturing and other types of diagenetic such as
neomorphism and bioturbation. Through the petrographic study the types of
porosity were identified. While, the porosity ratios was determined from the density
and the neutron logs. According to the results of these analyses, the porosity
of Jeribe formation changes from 11.4% and 25.6%, with an average rate of
17.3%. These values are described as good porosity, and had probably been
enhanced by some diagenetic processes by dolomitization and dissolution
followed by secondary effects from tectonics activities.

Particularities of Integration of the Migrants of the North Caucasus Republics in Local Host Environments
Authors: Kuznetsov Igor M.
Published: December 2018

The article discusses the particularities of the integration of internal migrants from North Caucasus republics in the host environments of Russian regions, differing in the level of economic development and the historically established ethnosocial structure of the population. The empirical basis for analysis of the particularities of migrant integration was made up of databases of regional surveys conducted in 2014–2016. The similarities/differences in the interpretation of terminal and instrumental values are the integration criteria in the surveys. Based on the analysis of similarities/differences in the interpretation of terminal value-conscious meanings by representatives of the host population and recent migrants from North Caucasus republics, it is concluded that visitors from the North Caucasus republics are quite integrated into the identification context of the local host environments. Their estimations of the events that are occurring currently in Russia and abroad are scarcely different from the corresponding estimations of the local host environments (and from those of the Russians as a whole). These entrants differ just in stronger adherence to their ethnocultural conventions and customs. Significant differences were found in the interpretation of instrumental values. These differences can on the one hand be explained by the difference in the economic status of a certain host region and the region of the migrants’ outcome, as well as by a more modernized socio-cultural environment of the daily activities of the host regions, regardless of economic status. On the other hand, the given differences are conditioned by the socialization environment which is more traditionalist in the areas of migrants’ outcome. Prospects for the successful integration of migrants from the North Caucasus republics are connected, first, with the development of the spheres of productive economy in the territories of these republics and, second, with the erosion of importance of nationality as social capital in the host territories.
The Problem of Subjectivity in the Sociology of Management
Authors: Merzlykov Andrey A.
Published: December 2018

The article focuses on the "subjectivity" concept consideration. The scientific representations genesis of this definition presented in socio-humanitarian disciplines. Particular attention is paid to the peculiarities of the subjectivity study in the sociology of management, which is aimed at identifying and studying ways how subjects constructing relations in order to jointly solve significant problems. The attention is focused on the fact that in management practice the need to study subjectivity is actualized in situations of assessing the nature of social relations between the power-management vertical and the population. The subjectivity of the population is characterized through a system of interactions between society and the authorities, where the ability to self – organization as a full-fledged social subject is important for society, and for the authorities -the creation of conditions for constructive dialogue. Verification of the proposed assumption requires splitting the category of subjectivity into a set of indicators, with which it is possible to empirically, and then theoretically investigate this phenomenon. In this regard an attempt is made to systematize sociological indicators of this the phenomenon study. They include indicators of group formation of individuals in social communities; indicators of the social communities’ formation in collective social subjects; and indicators aimed at assessing the regulation degree of intersubjective interaction.

Tingkat berpikir kreatif atau disebut TBK dikategorikan menjadi 5 tingkatan, yaitu TBK 4 (sangat kreatif), TBK 3 (kreatif), TBK 2 (cukup kreatif), TBK 1 (kurang kreatif), dan TBK 0 (tidak kreatif). Hasil penelitian menunjukkan bahwa 3 siswa reflektif dinyatakan sangat kreatif (TBK 4) dan 4 siswa reflektif dinyatakan kreatif (TBK 3). Persentase tingkat berpikir kreatif untuk kelompok siswa reflektif adalah 42,86% siswa masuk dalam kategori TBK 4 dan 57,14% siswa masuk dalam kategori TBK 3. Untuk siswa impulsif, tingkat berpikir kreatif yang dapat diidentifikasi adalah 2 siswa dinyatakan kreatif (TBK 3), 3 siswa dinyatakan cukup kreatif (TBK 2), dan 3 siswa dinyatakan kurang kreatif (TBK 1). Persentase tingkat berpikir kreatif siswa impulsif tersebut berturut-turut adalah 25% siswa masuk dalam kategori TBK 3, 37,5% siswa masuk dalam kategori TBK 2 dan 37,5% siswa masuk dalam kategori TBK 1. Hasil tersebut menunjukkan bahwa siswa reflektif lebih memiliki kreativitas dibandingkan dengan siswa impulsif.
