Abstract:This article is dedicated to analysis of the traditionalist agenda, promoted by Russia, in recent debates in the United Nations Human Rights Council (‘Traditional values’ from 2009 to 2013, ‘Protection of the family’ from 2014 to 2017). The traditionalist agenda could be interpreted as yet another chapter of contextualist opposition to the universalist application human of rights and as a successor to the cultural relativism in human rights promoted in the past by the Organization of Islamic States or countries from the Global South. This article seeks to challenge such an interpretation and instead makes the argument that the traditionalist agenda employs novel aspects of illiberal norm protagonism in the human rights sphere. The article undertakes an in-depth analysis of the discourse coalitions of both supporters and opponents of the traditionalist agenda, using the tools of discourse analysis in international relations and drawing on a constructivist approach to norm diffusion in international organisations.
The processing of friable materials used in metallurgical industry for production of definite size classes requires operation of crushing machines, including single-roll machines. Parameters of crushing process are degree and efficiency of crushing. The crushing degree is estimated by the ratio of dimensions of the initial crushing and resulting pieces and depends on the size of gap between the roll and the fixed jaw. Crushing efficiency is determined by mass of material crushed by consumed electric energy unit, and depends mainly on strength of crushed material. In order to reduce energy consumption needed for crushing, a single-roll crusher was developed at Siberian State Industrial University with forced feeding of crushing piece into the fracture zone due to the locker located on the roll. Forces of technological resistance appearing during machine operation are the main initial values for machine drive power and structural elements strength testing, thus, the operation power analysis is an integral stage in the design of any machine, including a crushing one. In the present work, forces acting on a crushing piece from roll side and fixed jaw in vertical and horizontal planes are identified. Based on the results obtained, it was determined that internal compressive forces acting on piece of crushing material cause action of normal compressive stresses in a piece, as well as an internal torque effect, which causes shearing stresses action, i.e. a complex stress state is generated in a fractioned piece with simultaneous action of normal and shearing stresses, under which action a fractioning piece is destroyed. Thus reduction in energy consumption for crushing is achieved, with all other conditions being equal. It reduces energy consumption of a single-roll crusher with forced feeding of material into the crushing zone.
The article is devoted to the problem of improving the quality of images recorded using low-resolution optical instruments, including diffraction-based cameras. A two-stage image correction technology is proposed. At the first stage, the correction is carried out using a linear FIR filter with a centrally symmetric frequency response in the form of quadratic and exponential functions. The resulting image is then processed with a non-linear filter that performs computer retouching of image areas characterized by a noticeable brightness difference. This procedure is only performed on those pixels in which the absolute value of gradients in different directions is sufficiently high, that is, they are located on the borders of areas with different intensity levels. This allows us to avoid noise amplification in the background, which is typical of traditional filters. The examples of the implementation are provided, showing the possibility of achieving high sharpness and illustrating how the filter can be adjusted by visual perception.
The article compares two filters: a Butterworth filter and an asymmetric SEfilter.The experimental studydetermines their advantages and disadvantages.Also,experiments based on the peak signal-to-noise ratio(PSNR) metricshowvisual evaluation. The results of experimentsshow that a symmetric filter better restores images usinga small set of continuous function parametersthatare distorted by a low-frequency Gaussian filter.
The wellknown energyefficient method of crushing in a singleroll crushing machine with smooth rolls, in which a complex stress state is created in the destroyed piece, has a significant disadvantage – low productivity due to a limited degree of crushing. In order to increase productivity, singleroll crushing machines are equipped with stop blocks on the roll, which ensure the forced supply of the destroyed material to the crushing zone. The maximum possible number of stop blocks should be installed on the roll, and the condition of guaranteed feeding of the piece into the fracture zone must be met. The developed mathematical model allows one to calculate the maximum possible number of stop blocks, which ensures guaranteed nipping of the original piece into the destruction zone.
