Authors: Charikov P N , Afanasenko A G 
Published: January 2020

Abstract
Today, the departments of various universities have implemented databases in the form of Web sites. The information environment of the department is a huge data warehouse. Modern database management systems allow to effectively store and process data, but, unfortunately, these tasks implementation is not enough for personnel management. The trends in the higher education development in Russia indicate that it is necessary not only to store data, but also to control the department development in educational, scientific and other areas of activity. For this it is proposed to implement a system for calculating, maintaining and visualizing the department’s rating and introduce it into the existing Web portal of the department. This system will not only simplify the obtaining, calculation and storage of the required data on the department rating. It will also provide the required indices in a visual and understandable way.

Authors: Nureev I I , Agliullin T A , Kadushkin V V , Kurbiev I Y , Proskuriakov A D 
Published: January 2020

Abstract
The work proposes and experimentally demonstrates the feasibility of creating a combined sensor system for simultaneous local and distributed temperature and strain measurements using the Brillouin optical frequency distributed analysis. The system uses a quasi-distributed approach based on two-element fiber Bragg structures (TEFBS), which makes it possible to carry out simultaneously distributed and local measurements of temperature. The proposed highly integrated circuit uses a conventional narrow-band optical source corresponding to the spectral range of temperature measurements, and a common receiving module on the same sensor fiber. For distributed detection, a single-mode optical fiber is used, and for the local detection, two TEFBS pass-through and reflective types are used.

On the embedding parameters in kernel identification problem of nonlinear dynamical systems
Authors: Antropov N R , Agafonov E D 
Published: January 2020

Abstract
Dynamical models are of fundamental importance in many problems such as simulation, optimization and prediction. In identification problem of dynamical systems an input vector is typically considered as delayed vector of previous outputs. Embedding lag and embedding dimension should be chosen correctly. Identification of nonlinear systems is generally performed using kernel-based methods since they do not require any additional information about system structure. A common question in identification of dynamical system is sensitivity of kernel-based models to selected embedding lag and embedding dimension. The paper presents simulations of the kernel least mean squares algorithm on one-step prediction problem for various values of embedding lag and embedding dimension. It is shown that optimal embedding lag and embedding dimension is dependent on model parameters, while usage of optimal model parameters decreases the value of optimal embedding dimension.

Published: January 2020

Abstract
Blockchain-based applications have become increasingly popular in recent years. Security concerns are rising as blockchain users are becoming aware of how their private data is stored across this decentralized network of computing nodes. Formal verification allows developers to improve software quality and hence make it more secure. The main hypothesis of this paper is that it is achievable to perform formal verification of a model that represents a smart contract responsible for user registration. In order to test the hypothesis, we have created a model of such a smart contract and checked it against a set of formal constraints. As a result of the conducted study, a conclusion can be made that the hypothesis is correct.

The assessment of the individual resource of the welded joint during repairs of the technological pipeline
Authors: Naumkin E A , Rubtsov A V , Kulakov P A , Berdin A R 
Published: January 2020

Abstract
The relevance of research is due to the necessity to develop recommendations for assessing the “individual” resource of welded joints of technological pipelines using non-destructive testing methods for the timely detection of welds with the smallest resource to ensure reliable operation of equipment and the inadmissibility of premature failure in the weld zone. The task is to develop recommendations for determining “individual”resource of welded joints of technological pipelines with a different level of edge displacement and imperfection by introducing correction factors into the modified Coffin-Manson equation based on the mechanical characteristics of the yield strength and strength, determined as a result of static tensile testing of samples of various sections of welded joints with maximum acoustic and magnetic signals according to the results of flux-probe and ultrasonic non-destructive testing. For research, 6 pipe fragments were selected made of steel 20 with dimensions of 159×7 mm and a length of 45 mm each. Fragments were welded together by different types of welding with different displacements of the edges of the welded elements. The authors developed recommendations for assessing the “individual” resource of welded joints of technological pipelines. It is shown that the introduction of correction factors depending on the amount of offset of the edges of the welded joint allows to increase the accuracy of the predicted durability of individual welds by 4% for manual and 11% for semi-automatic welding, respectively.
Ablation properties of ZrC-SiC-HfB2 ceramic with different amount of carbon fiber under an oxyacetylene flame
Authors: Shojaie-Bahaabad Maryam , Hasani-Arefi Alireza 
Published: January 2020

Abstract
In the present work, a carbon fiber reinforced ZrC-20 vol% SiC-15 vol% HfB2 composite was produced by pressureless sintering method. Carbon fiber with various weight percentages (0, 10, 20, 30) was added to the milled ZrC-SiC-HfB2. The mixed powders were pressed and sintered at 2200 °C for 2 h. The microstructure and mechanical properties of the specimens were investigated by Scanning Electron Microscope (SEM) equipped with EDS spectroscopy, XRD analysis and hardness and toughness tests. The ablation resistance of the composites was performed by oxyacetylene torch. The results showed that as the carbon fiber content was increased, the porosity and toughness were increased as well, while the hardness and density were decreased. During the ablation test, the outer surface of the composite underwent a sintering process and formed a dense layer of Zr-Hf-Si-O on the surface. ZrSiO4 and HfSiO4 were also created after cooling, so these phases played a pinning effect and prevented the crack propagation. The results also showed that linear and mass ablation rates were increased with increasing the weight percentage of the carbon fiber. SEM analysis with EDS further revealed that with increasing the carbon content, the defects in the formed oxide layer on the composite surface were increased due to the evaporation of SiO2 and the decrease in the pinning effect of ZrSiO4 and HfSiO4 phases as well as the phase transformation of the remained ZrO2 and HfO2. As a result, as the carbon fiber was increased, the ablation resistance of the composite was decreased.

Authors: Wang Yu-Xing , Tang Yu-Jiao , Wan Wen , Zhang Xia 
Published: January 2020

Abstract
This study determines the effects of nickel (Ni) doping on the composition, phase structure, chemical valence state, hardness, and toughness of CrAlNiN coatings. CrAlNiN coatings with various Ni contents (0.00 at%–27.71 at%) were deposited on the surfaces of M2 tool steel and monocrystalline silicon (Si) using unbalanced magnetron sputter ion plating. The results showed that the CrAlNiN coatings possess a nanomultilayer structure, maintaining the face centered cubic crystal structure of the chromium aluminum nitride (CrAlN) coatings. The Ni in the coatings acts as a toughening phase to ease stress, to increase resistance to crack growth, and to delay the generation of cracks, thereby having an obvious toughening effect. At an Ni content of approximately 20.33%, the Ni toughening phase in the modulation layer tends to saturate and the effect of continuing the increase in Ni content is limited from the viewpoint of improving the toughness.

Abstract
Zinc oxide (ZnO) nanoparticles were immobilized on polyurethane foam (PUF) and employed for the degradation of Acid black 1 dye (AB1). The ZnO/PUF was characterized by x-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive x-ray (EDX) techniques. Process variables i.e., dye concentration, pH, concentration of H2O2, irradiation time were optimized for maximum degradation of dye. ZnO/PUF showed promising efficiency for the degradation of AB1 dye and up to 86% and 65% dye degradation was achieved under UV and solar light irradiation at neutral pH, 4% H2O2, 240 min/sunlight and 75 min/UV irradiation time using 40 mg l−1 dye initial concentration. The optimum conditions were applied for the treatment of textile wastewater and biological oxygen demand (BOD) and total organic carbon (TOC) were reduced up to 70% and 80%, respectively. In view of promising photocatalytic activity (PCA), ZnO/PUF could possibly be used for the treatment of wastewater contains dyes.

Published: January 2020

Abstract
The internal elliptical hole defect in the Ti-6Al-4V titanium alloy sheet strongly affects the material mechanical properties during the bending process. In this study, the finite element method (FEM) is used to study the effect of internal hole on mechanical properties of the sheet subjected to the V-shaped bending. The fracture damage, the equivalent strain and the principal stress in the sheet with elliptical hole (the defect sheet) and the hole-free sheet (the perfect sheet) are analyzed contrastively under different punch speeds and radii. The results show that the load in the defect sheet and the perfect sheet has different trends during the bending process. Compared to the perfect sheet, both the damage and the equivalent strain in the defect sheet obviously increase, and the distribution of the principal stress in the bending zone of the defect sheet has a significant change. The hole causes the different evolution of the maximum damage, the equivalent strain, and the maximum tensile and compressive stresses with the increase of punch speed and radius for the defect and perfect sheets. The current results serve a feasible approach to predicting the fracture of the sheet with internal hole during the V-shaped bending process, and provide a guidance for the V-bending experiments of the defect and perfect sheets in the subsequent work.
