Benziodoxole-Derived Organosulfonates: The Strongest Hypervalent Iodine Electrophiles and Oxidants
Authors: Zhdankin Viktor V. , Yusubov Mekhman S. , Postnikov Pavel , Yoshimura Akira 
Published: December 2019

This account describes the development of organosulfonyloxy-substituted iodine(III) and iodine(V) benziodoxole derived reagents, which are thermally stable compounds with useful reactivity patterns. Iodine(III) benziodoxoles and pseudobenziodoxoles are powerful electrophiles and mild oxidants toward various unsaturated compounds. In particular, pseudocyclic benziodoxole-derived triflate (IBA-OTf) is an efficient reagent for oxidative heteroannulation reactions. Aldoximes react with nitriles in the presence of IBA-OTf at room temperature to give 1,2,4-oxadiazoles in high yields. Moreover, IBA-triflate is used as a catalyst in oxidative heteroannulations with m-chloroperoxybenzoic acid as the terminal oxidant. The iodine(V) benziodoxole derived tosylates, DMP-tosylate and IBX-tosylate, are superior oxidants for the oxidation of structurally diverse, synthetically useful alcohols, utilized as key precursors in the total syntheses of polyketide antibiotics and terpenes. And finally, the most powerful hypervalent iodine(V) oxidant, 2-iodoxybenzoic acid ditriflate (IBX·2HOTf), is prepared by treatment of IBX with trifluoromethanesulfonic acid. According to the X-ray data, the I–OTf bonds in IBX-ditriflate have ionic character, leading to the high reactivity of this reagent in various oxidations. In particular, IBX-ditriflate can oxidize polyfluorinated primary alcohols, which are generally extremely resistant to oxidation.1	Introduction2	Iodine(III) Benziodoxole Based Organosulfonates3	Pseudocyclic Iodine(III) Benziodoxole Triflate (IBA-triflate)4	Pseudocyclic Iodine(III) Benziodoxole Tosylates5	Iodine(V) Benziodoxole Derived Tosylates6	Iodine(V) Benziodoxole Derived Triflate (IBX-ditriflate)7	Conclusions

Abstract
A kind of metasurface cylindrical vector light (CVL) generator in the visible region is proposed. This kind of CVL generator consists of nanometer holes etched on silver film, and it can change any linearly or circularly polarized light into the CVL in nanoscale. The order of the generated CVL is controlled by the rotation of the holes and its polarization state changes with the incident polarization condition. The base transformation theory guides is used to design the metasurface. The numerical simulations for the transmission of the proposed CVL generators confirm the validity of the theoretical predictions, and they also provide the available parameters for practical metasurface devices. The experimental results verify the performance of the proposed metasurface CVL generators. This kind of vector light generator has the advantages of thin and compact structure, polarization multiplexing and convenient manufacture. This work paves a new path for designing the miniature devices to generate the vector light field and it will promote the applications of polarization devices in optical integration and micro-manipulation.

Application of association rules learning for studying the store history of a large retail chain
Authors: Ogurtsov D A , Dorrer M G 
Published: December 2019

Abstract
In this article the problem of goods clustering according to the probability of their joint presence in the transactions of the sale point was considered. The problem was solved by applying the algorithms for the formation of association rules based on real retail store transactions. The applicability of the algorithms of this class was assessed, the Apriori algorithm proposed by R. Agrawal was selected and implemented. Using this algorithm, the possibility of cutting off “random” goods in a cluster to create a consumer basket of the corresponding outlet was studied. It is shown that the most resistant to “random” associations are clusters with a small number of products in the cluster, and the higher the cluster size, the higher the likelihood of noisy search results with “random” goods with a high individual probability of their acquisition (‘support’ indicator). Further development of the proposed method may consist in its distribution to all transactions of the entire trading network and the transition from the tasks of organizing goods within the store (merchandising) to the tasks of forming assortment matrices for stores.

Abstract
This article is devoted to the preparation of the YOLO2 convolutional neural network for use in the robot artificial intelligence tracking module in air hockey competitions in the human-robot or robot-robot category. Such developments are unique in the sphere of artificial intelligence and robotic technologies. The task was to collect and prepare educational material, as well as further training and testing of the convolutional neural network to create a “vision” and further predict the trajectory of a fixed object. For this, the YOLO2 model was used, created by the developer Ali Farhadi in the low-level language C [1]. As a result of testing in the next game, the results of the correct detection of the object in the range of 80% were obtained, despite the lack of a standard camera position and poor image quality. In the future, the created system can be used in the further development of the AI robot systems and for creating tactics of behavior in various air hockey matches.
Study of longitudinal vibrations of stab knife refiners
Authors: Vikharev S , Zasypkina S A 
Published: December 2019

Abstract
The subject of research is the longitudinal vibrations of stab knife refiners. A model of the fibrous layer between the rotor and stator is developed. It is shown that it is advisable to use the Maxwell-Thomson model for liquid friction of the rotor and stator, and the Hooke elastic model for boundary friction. The formula for determining the dynamic stiffness of the fibrous layer is obtained. Dynamic and mathematical models of the refiner in the longitudinal direction are developed. The mathematical model is a system of linear differential equations with periodically varying coefficients (Mathieu-Hill equations). A method for calculating the amplitude of oscillations of the refiner rotor and stator is developed. According to this technique, Andritz 54-60-1c stab refiner was designed. Oscillation parameters of the refiner rotor and stator are determined theoretically and experimentally. The stator oscillation amplitude is 1.6–2.3 times smaller than the rotor oscillation one. In case of boundary friction, the amplitude of oscillations of the stator and rotor increases by 2–3 times in comparison with liquid friction. The oscillation amplitude of the rotor and stator in the longitudinal direction is comparable with the gap between these elements. Therefore, it is recommended while designing refiners, to develop methods and means of vibration protection, and during operation, to prevent boundary friction between headsets. The developed calculation procedure can be used in other industries, for example, mining and metallurgy.

Published: December 2019

Abstract
With the development of the facilities new materials with higher strength and performance characteristics are developed. But as these characteristics increase, others, such as machinability, deteriorate. In view of this, the question about the most sustainable method of machining, in particular cutting, came up. One of such methods is machining with the use of vibration cutting. The process of vibration cutting consists in superimposing on common kinematic scheme of machining the additional vibrating movement of a tool or workpiece, which is characterized by the direction, shape, amplitude and frequency of vibrations. Superimposing of vibrations on the tool or treated material during drilling, turning, grinding, forming and pressing provides a considerable physical effect of cutting force reducing and friction forces reducing, it facilitates the processes of flow deformations, increases the tools life and improves the quality of machining.

Published: December 2019

Abstract
Most of the currently existing microclimate control systems operate on the basis of traditional P, PI, PID controllers. But the work of such systems is effective only in a narrow operating range. With significant fluctuations in environment, it is required to reconfigure the parameters of these regulators each time. In such cases, maintaining comfortable conditions in the room is recommended by using intelligent control technologies, so-called fuzzy control systems, operating in terms of fuzzy logic. The aim of the paper is to research the possibility of implementation of intelligent control systems to maintain the comfortable microclimate in the premises and checking the adequacy of the system through simulation. The climate control system is based on fuzzy inference and provides forming the base of fuzzy production rules, fuzzification of input values, aggregation of truth of sub conditions of each rule, activation of conclusions and defuzzification process that generates an output signal to control the smart home functional devices. Procedures of the fuzzy inference and simulation are implemented in the Matlab programming environment using the Fuzzy Logic Toolbox and Simulink packages. The results of the paper showed that the developed intelligent microclimate control system for premises based on fuzzy logic provides a flexible self-tuning of the engineering equipment and maintaining the microclimate parameters at the required level.

Authors: Ivanov S L , Ivanova P V , Kuvshinkin S U 
Published: December 2019

Abstract
The article discusses various factors that have a significant impact on the performance of EKG-32R type powerful mining excavators. It was revealed that the most adverse effects are weather conditions that are different from the nominal ones for which mining machines are designed. The climatic factor includes the impact of solar radiation, low and high air temperatures, wind speed, humidity, fog, snowstorms, snow storms etc on mining equipment. The transformation of the properties of structural materials is also determined by the intensity and duration of exposure to these factors and their combination. A methodology is proposed for assessing the influence of weather conditions on the operation of mining equipment, which allows one to analyze the influence of each climatic parameter separately and evaluate the complex effect. It is proposed to take into account the influence of the climatic factor on the performance of mining excavators through a complex indicator - the weather stiffness index, which takes into account the parameters of any type of climate for the entire calendar period of the excavator exploitation.

Authors: Strizhenok A V , Ivanov A V , Suprun I K 
Published: December 2019

Abstract
There is a steady tendency to significantly increase the volume of extraction and processing of mineral raw materials on our planet in recent decades. It leads to an increase in the volume of industrial waste, which predominant method of disposal is placement on the Earth surface in the form of anthropogenic arrays. There are accumulated billions tons of waste in such anthropogenic arrays, but its height can reach 100 meters. It determines the deterioration of the sanitary and hygienic situation in these territories, an increase in the morbidity and mortality of the population, a decrease in the species diversity of animals and plants, violation and modification of natural landscapes, and loss of natural resources. In addition, such anthropogenic arrays are especially subjecting to the risk of emergencies, which can entail significant social, environmental and economic damage. In this regard, the development and implementation of environmental monitoring systems on the territory of the impact of industrial waste storages, which can quickly identify sources of anthropogenic load and carry out their timely elimination, is of particular relevance to society, the economy and the state. Monitoring of the state of components of the environment based on remote sensing data is one of the most innovative and developing areas of environmental monitoring today.

Published: December 2019

Abstract
The task of reducing friction in internal combustion engines is an important task of the development of transport engineering. As the analysis of literature sources shows, the problem of reducing friction losses in relation to internal combustion engines is usually solved for each individual friction pair, for example, a cylinder-skirt of a piston or a cylinder - compression ring. In this case, the measurement of friction is carried out mainly in stationary conditions. However, such approaches do not allow to identify the most critical, in terms of friction in all friction pairs of internal combustion engines, operating modes and do not allow to study and control the friction processes of all friction pairs in of the internal combustion engines. The developed dynamic methods of control of mechanical parameters of engines of rotational action and drives on their basis allow to synthesize a dynamic method of control of friction losses in the internal combustion engines, the scientific and technical justification of which is devoted to this work. Critical, from the point of view of the developed method, is the calculation of the value given to the axis of rotation of the crankshaft moment of inertia of the parts of the crank mechanism, changing during one revolution of the crankshaft.
