Abstract
In the design process of the transmission line of the traditional substation system, the plans and decisions often made by people, resulting in unsatisfactory line design results, which are not the most economical optimal results, and they are not even considered in the preliminary planning. Going to areas where lines cannot be erected has caused slow progress and poor accuracy in the feasibility study stage. This paper combines the ant colony intelligent algorithm with the geographic information system, and proposes a substation transmission line optimization model, which outputs the optimal path by inputting geographic information data. This model analyzes the entire process of the transmission line design stage and realizes the intelligent line selection. The analysis of the example in the article proves that the model has a better auxiliary function for the work of the substation line planning stage.

Authors: Wang Shoujin , Zhao Guanghe , Liu Jifei 
Published: February 2021

Abstract
The traditional text captcha adds adversarial perturbation based on a single character, and it is necessary to joint and compound the captcha picture, so that the characters and the background are easy to segment. In order to strengthen the security of text captcha, an AECAPTCHA text captcha defense algorithm with overall adversarial perturbations is proposed. The algorithm uses multi-label classification training text captcha as a pre-training model. Therefore, the AECAPTCHA algorithm is used to generate multi-character overall adversarial perturbation, eliminate the steps of splicing, compositing, and adding colors, then superimpose to generate safe text captcha with adversarial examples properties. The experimental results show that text captcha with the overall adversarial perturbation reduced the accuracy to 0.06%, effectively improves the security of the text captcha, and does not affect the user’s rapid identification and use.

Published: February 2021

Abstract
This paper describes the study on mechanical properties at different test temperatures of SA-738 Gr.B plate in both delivery state and simulated post-welding heat treatment state. And the properties of the plate were characterized by tensile tests, Charpy impact tests and drop weight tests. We found that as temperature increasing, the strength of the SA-738 Gr.B plate decreased when temperature was below 200°C. While as temperature decreasing, the Charpy impact absorb energies decreased, that is, toughness of the plates became worse gradually. Through drop weight tests, we obtained the nil-ductility transition temperature for the plate. The tests data indicated the SA-738 Gr.B plate possessed good strength and toughness, which can meet the design requirements for the containment vessel and some other components of nuclear plant. The tests data also showed that post-welding heat treatment may influence both strength and toughness, so attention should be paid to simulated post-weld heat treatment when purchasing materials for plant construction. By optical microscope and scanning electron microscope, microscopic pictures have been obtained for the plate to help analyze the properties of this material, and the microstructure was the ensurance of the strength and toughness.
Synthesis of hydrogrossular and hydroxysodalite from blast furnace slag using alkali fusion for fixation of HCl gas
Authors: Wajima T , Takahashi T 
Published: February 2021

Abstract
Blast furnace (BF) slag, one of the by-products of iron- and steel-making plants, was converted into the product including hydrogrossular and hydroxysodalite using the alkali fusion method for HCl gas fixation. The slag was transformed into the alkali-fused slag with reactive phases via alkali fusion, after which the fused slag was added to distilled water with Al(OH)3 to synthesize the product including a hydrogrossular by heating at 120°C for 24 h. The product including hydrogrossular, hydroxysodalite and calcite can be synthesized with addition of Al(OH)3, and could remove HCl gas at high temperature to fix Cl in the product. These results suggest that a novel product able to fix HCl gas at high temperature can be synthesized from BF slag via alkali fusion.

Published: February 2021

Abstract
Icing environment incurs great inconvenience to production and life. In order to study the physical characteristics of accreted ice, an experimental platform for ice detection is performed in this paper, and the influence of icing parameters is analyzed by using active infrared thermal wave nondestructive detection system and universal mechnical testing machine, we analyze the influence of icing parameters are icing height, icing diameter and freezing time. With the help of the logarithmic function of temperature difference and time in infrared thermal wave experiment, the relationship between the inflection point of stress-strain curve in compression strength tests and icing parameters is discussed. Results show that larger icing height, smaller icing diameter and longer freezing time will delay the turning point of logarithmic temperature difference curve with time; whereas larger icing height, appropriate freezing time and larger icing diameter will enhance the compressive strength of accreted ice. In addition, the strain level is also one of the factors closely related to the compressive strength. These conclusions lay the foundation for further research on the physical characteristics of the infrared detection of ice.

Risk assessment of transport dangerous situations
Authors: Smirnova O V 
Published: February 2021

Abstract
Transport safety assessment plays a huge role in theory and practice of implementation of transport management systems. It should be noted that ensuring the transport safety is inextricably linked to identification of potentially dangerous transport situations and their risk assessment. To better manage transport risks we propose to apply a new integrated approach which allows to take into account the source of the threat, the degree of objects’ protection, kinds of threats, extent of damage in the event of dangerous situations, magnitude of the dangerous situation. This approach is anchored to systematic analysis of causes and conditions of formation of dangerous situations. Also, it provides timely forecasting of their development and consequences. Therefore, it is necessary to develop a new approach to transport risk assessment which will be able to effectively evaluate occurrence of dangerous transport situations. In this paper we present components of transport safety and provide a list of typical objects of transport infrastructure. Transport safety model and algorithm for identification of potentially dangerous transport situation is proposed. Also, we consider a new integrated approach based on transport risk assessment method. It is worth highlighting that the proposed method of transport risk assessment allows taking into consideration the uncertainty linked to the occurrence of dangerous transport situations and their conditions. The specified method can be widely used in modern geographic information systems for analysis of transport emergencies.

Published: February 2021

Abstract
Socio-economic processes informatization is largely implemented by using various documents electronic storage, including scanned handwritten texts or their fragments images, in particular, in the form of officials’ original signatures. Among the very diverse tasks of handwritten documents scans electronic repositories computer analysis, the direction of automatic search for images fragments, that contain outlines of key words of interest, is quite relevant. The search for such fragments is significantly hampered by the variability of the letterforms, even by the same author. Therefore, it is advisable to use a fragment from the analyzed text as an initial sample. Thus, we are talking about the fragments precedent identification. In this case, a complicating factor is the impossibility of using many identical objects in training, and only one is available. Therefore, the problem of forming an artificial sample, which elements preserve some common characteristic property, arises. In this work, the authors substantiated the application adequacy of the original sub-band approach, which is based on the concept of the data segment Euclidean norm sub-band part and the mathematical apparatus of sub-band matrices obtained on this basis. Decision procedures for the handwritten text fragments sub-band identification were developed, including training on a single precedent.

Authors: Jemioło S , Franus A 
Published: February 2021

Abstract
The paper presents a hyperelastic material model which is intended to describe slightly compressible materials with encountered the Mullins effect. It is assumed the volumetric-isochoric stored energy function split regarding the primary response of a material. Constitutive equations based on the concept of pseudo-elasticity are derived. The problems of a simple uniaxial compression/tension involving one finite element and a compression of a ball are solved using ABAQUS. The material model is defined with the help of user subroutine UHYPER in terms of the primary material response. Its main advantage is a physically correct description of volumetric changes while the polynomial model in ABAQUS does not meet basic growth conditions. In order to include the Mullins effect, it is combined with available in the software library the Mullins effect material model which is based on Ogden-Roxburgh proposition of stress softening function. Experimental data on synthetic rubber neoprene published in the literature is utilized.

Authors: Bobyleva T , Chernik V , Shamaev A 
Published: February 2021

Abstract
The article investigates the problems of control of dynamical systems with nonlocal terms of the convolution type using a force distributed over the area in which the motion is considered. The conditions are established under which it is possible to bring the system to complete rest with the help of a distributed force limited in absolute value. The case of one spatial variable is considered, but the proposed spectral method of research can be generalized to dimensions two and three. A connection is established between the behavior of the Fourier coefficients of the initial condition and the solvability of the control problem. The method can be used for mechanical systems with hereditary properties that arise in structural mechanics.
