Labeling requirements as one of the tools for non-tariff regulation of imports of Ukrainian food products to China

The article analyzes the dynamics and structure of international trade in Ukrainian food products with China. The opportunities of Ukrainian food producers to meet the demand of Chinese consumers are considered. The tools of the Chinese non-tariff trade policy regarding the import of food products (licenses, certificates of quality or compliance, certificates of origin, quality standards, requirements for packaging and labeling, legislative acts, sanitary and phytosanitary requirements) and their impact on trade with Ukraine are determined.


The article is devoted to the development of biometric identification methods based on new filtration methods. Biometric identification systems need constant improvement, because they often work slowly and give the wrong result. To increase the reliability of biometric image recognition, the method is formed, which is formed from the stages: segmentation, normalization, local orientation estimation, local estimation, spine frequency estimation, Gabor filter implementation, binarization, thinning.


Understanding the tradition, innovation and national identity of examples of wooden temple buildings, in particular, Ukrainian churches, certain trends are identified, which in their essence become the main ones, regarding the intensity of development in temple construction. The factors of tradition and innovation are identified as important mediums for establishing the national identity of the image of wooden temple buildings, and their expression in the modern temple-building process of creating a Christian shrine.

Рredominant microflora of natural and wastewaters of lviv region

Quantitative and qualitative composition of microorganisms have been determined by the microbiological methods of the analysis of natural waters and industrial wastewater. It is shown that the dominant microflora of the studied waters are Diplococcus, Sarcina, Bacillus, Pseudomonas bacteria types, blue-green algae of Oscillatoria types, as well as Saccharomyces yeast types. Morphological, physiological and cultural characteristics of colonies grown on nutrient media were studied to identify microorganisms.

On application of the histogram of oriented gradients method to vehicles identification

Development of theoretical background, methods and algorithms for identification of visual objects has begun when the first computers appeared. Application of various object recognition techniques in modern technical systems is boosted by fast development of powerful, small and relatively cheap digital devices for data processing that become more and more common these days. In this paper, we study the application of the histogram of oriented gradients (HOG) method to the problem of identification of three kinds of vehicles: cars, planes and ships.

On a method of image reconstruction of anisotropic media using applied quasipotential tomographic data

An algorithm for solving the coefficient problems of parameter identification of anisotropic media using applied quasipotential tomographic data is modified for the case of presence of more specific a priori information about the eigendirections of the corresponding conductivity tensor.  Its application is quite common in practice, in particular, in medicine, where the object of such study may be the medium with fibrous or layered areas (which includes muscles, bones, etc.), inside which there are streams of non-spherical particles (e.g.

Spatial modeling of multicomponent pollution removal for liquid treatment under identification of mass transfer coefficient

A generalized spatial mathematical model of the multicomponent pollutant removal for a liquid treatment is proposed. Under the assumption of domination of convective processes over diffusive ones, the model considers an inverse influence of the determining factor (pollution concentration in water and sludge) on the media characteristics (porosity, diffusion) and takes into account the specified additional condition (overridden condition) for estimation of the unknown mass transfer coefficient of a small value.

Estimation method for a set of solutions to interval system of linear algebraic equations with optimized “saturated block” selection procedure

The paper substantiates the necessity of applying a new method for the formation of a set of basic equations in the problem of localizing solutions to an interval system of linear algebraic equations (ISLAE) on the basis of a “saturated block”. The method is based on  solving the problem of optimization. Th e minimization of the maximal prediction error by using interval models the parameters of which belong to the localization area of ISLAE solutions is  chosen as a criterion.

On a numerical quasiconformal mapping method for the medium parameters identification using applied quasipotential tomography

The problem of parameters identification of the bursts of the medium conductivity coefficient according to the tomography of the applied quasipotentials is considered. The method of image reconstruction is suggested, according to which the problem of analysis is reduced to the application of numerical methods of quasiconformal mappings, and the problem of synthesis is reduced to the solving the problem of parametric identification. The results of numerical experiments are presented and their analysis is carried out.
