Authors: Nie Jiachen , Cao Ning , Chen Xinghan 
Published: February 2021

Abstract
The observation of gravitational wave opens a new window for both physics and astrophysics. Among the models of the formation of binary black holes (BHs), some suggest the existence of circumbinary disk, which may provide the material to ignite the electromagnetic radiation observable to modern astronomical facilities. In this work, we investigate the consequences of such circumbinary disk, with an emphasis on the reduction in the BH-BH merger timescale, i.e. the total time necessary for the gravitational wave events to happen. We find that, the circumbinary disk excites a tidal torque onto the BH-BH system, and it dominates the angular momentum transfer (outward) when the BH-BH separation a> xxx. Theoretical implications of this result are discussed.

Abstract
In order to study the spatial distribution of biological and ecological patterns on the territory of the Volga region and Western Kazakhstan, geobotanical indication of flooding and salinization of the lands these regions was carried out. Geobotanical indication is used in the study, assessment, mapping and monitoring of territorial complexes and their components and is based on the analysis of the relationships of the geographical envelope as a whole. The article is the result of many years of interdisciplinary research. It is based both on the data obtained by the authors as a result of agro-landscape and ecological zoning and in the course of field expedition research, and on the analysis of long-term series of statistical information and literature sources. Intensive economic activity that requires the use of large amounts water resources, against the background of modern climate changes, leads to waterlogging in large areas. The weakening or termination of economic activity, the decrease in the volume of water resources used under certain conditions leads to the spread of land salinization. Flooding and sal-inization of arid lands near reservoirs, channels, reclamation facilities, functioning and abandoned irrigation fields, etc. occupy significant areas and are of great importance as environmental problems in the Volga region and Western Kazakhstan. The most dynamic and fast-responding biotic component of ecosystems to the occurrence of flooding and salinization is vegetation.

Abstract
In this article lays the foundation for a program to protect various crops from a complex of diseases. The program is open for inclusion of new modules. As basic components, it uses previously developed models to protect wheat from brown rust, powdery mildew, Septoria and their complex. The new program has increased the detail of calculations based on the model of large-scale distribution of brown rust uredospores in wheat. Significant changes have been made to the basic module for protecting wheat from brown rust, which uses the results of calculations based on a large-scale spread model with a reduced space step and is the basis for comparison with other diseases. The new program was also adapted for the case of poorly defined initial conditions about the actual defeat of wheat by brown rust, powdery mildew and Septoria. Equations are given for estimating wheat damage and crop losses if there is no data on varietal characteristics, regardless of the phase of plant development.

Abstract
Temperature and relative humidity affect the test of geomembrane. Here, using mathematical statistics, we analyzed the influence of temperature and relative humidity during state regulation and test on the results. The test data of geomembrane were obtained by changing the temperature and relative humidity ranging from 18°C to 25°C and from 50% to 70% respectively. Variation characteristics of discreteness and numerical value of test results with temperature and relative humidity are obtained by statistical analysis method. The results show that the influence of temperature and relative humidity on the test results stability is the change of numerical value and distribution characteristics. Under different temperature and relative humidity, the coefficient of variation of the test value of mass per unit area is 3.4% ∼ 4.1%, and the coefficient of variation of average value is 0.3%, which shows good stability; the coefficient of variation of thickness test value is 2.9% ∼ 7.0%, and the coefficient of variation of average value is 6.8%, and the value decreases with the increase of temperature.

Published: February 2021

Abstract
Because of the rapidly increasing total electric load of buildings, effective electric load management should be achieved quickly. This can be realized via electric load forecasting. In this study, a novel clustering-based hybrid prediction model is proposed to predict the 24-daily electric load of buildings. In this study, fuzzy c-means (FCM) clustering, ensemble empirical mode decomposition (EEMD), and some intelligent prediction algorithms are combined. FCM is used to extract the daily data exhibiting similar features, whereas EEMD is used for breaking down the optimal prediction algorithm is selected for each component, and the prediction results are integrated. When compared with the remaining conventional prediction models based on real data, the proposed hybrid model exhibits higher prediction accuracy.

Published: February 2021

Abstract
In this research, phosphogypsum composite cementing material using phosphogypsum powder, slag powder, fly ash and cement were prepared as the main cementing materials, and sodium silicate was used as the activator. The influence of the cement content of 0 wt.%, 5 wt.%, 10 wt.%, 15 wt.% and the change of 0%, 2%, 4% alkali equivalent on the mechanical properties of cementing materials was studied, the types and content of admixtures suitable for phosphogypsum cementitious materials were also studied. The cost of the materials used was calculated and analyzed. The results showed the increase in cement content and alkali equivalent will improve the mechanical properties of the cementitious material, and the strength can reach 23.0 MPa; the change of alkali equivalent had a more obvious impact on the early (1 d) mechanical properties of the cementitious material than cement; when these two factors synergistically worked, the cement content should not exceed 10 wt.%, or the mechanical properties of the material would decline; the effect of using the naphthalene-based water-reducing agent was better than that of the polycarboxylic acid water-reducing agent, and when cement, sodium silicate and naphthalene water reducer were used together, the maximum compressive strength of 7 d reached 24.4 MPa, which was higher than 39.4% of the sample without water reducer. The ratio used in the experiment was relatively low cost, which had a great reference value for the comprehensive utilization of industrial by-product phosphogypsum.

Published: February 2021

AbstractAlthough wheel is an ideal method of locomotion and the invention of the spoke wheel made a wheel lighter and swifter, a wheel cannot function well on slanted or rough surfaces. Further, the load support of the wheel is limited to a point of the whole wheel in contact with the ground. In rough and rocky terrains, wheels become ineffective or not able to serve the purpose. On realizing this fact, a new design and fabrication is suggested and a walking robot is designed accordingly. In the practical life, the usage of robots has been felt especially in search and rescue operations, extraterrestrial exploration and many more such applications. In these areas, the existing wheeled robots are not able to perform well and hence they can be replaced with walking robots of special design. In distant areas, many expeditions of walking robot need the tele-operation mode. Yet, sensing the terrains and controlling the robots become difficult for a human operator with the available capabilities and hence the walking robot should be designed in such a way that even with limited feedback from the remote operator, it should have adequate autonomy to take due advantage of its competency and capabilities. The paper envisages a new method of real-time motion planning on rough and rugged surface and in this paper, an octopod is designed, developed and fabricated accordingly.

Abstract
High performance and precision characteristics in automatic welding technology continues to find a wider application in diverse industries. A welding simulation for seam tracking based on a purpose-built vision sensor is designed to improve the welding efficiency of robotic Gas Metal Arc Welding (GMAW). A shape-matching algorithm is suggested and simulated using graphical device design software LabVIEW to achieve a reliable and precise seam tracking process that is sensitive to groove styles. Relevant modules such as smart parameter setting, image capture and processing, welding expert database, robot communication and route planning modules are included in the software. The main feature of using vision technology is to acquire direct images of the real-time weld path and accurately process them. This is directly linked to seam tracking accuracy. The coordinates for the ABB industrial robot are fed through the profi-bus cable through the use of the Virtual Instrumentation with data acquisition system (DAQ) in NI LabVIEW.

Abstract
Fiber Reinforced Concrete FRC can be used for a variety, of applications. Fibers are utilized in concrete crack requiring reduction of physical property protection, drying reduction and improved strength and toughness, increased service life and decrease bleeding from water, concrete permeability, and construction value. The utilization of sisal, a natural fiber with increased mechanical efficiency, as reinforcement in an exceeding matrix based on supported cement. The proportion of sisal fiber used in concrete ranged from 0.1% to 2% of concrete and length of fiber 50mm to 60mm fiber length in concrete with aspect ratio. By adding short fibers, tensile strength is improved, thaw resistance is frozen, impact resistance, and concrete brittleness are reduced. In general, fiber does not enhance the concrete strength, as the replacement moment is reduced in the reinforcement of structural steel. This paper also represents fiber limitation content, environmental aspects, and FRC is the modern technical enhancement in the civil substructure. This review paper also describes the compressive strength test, flexural strength test, tensile strength test, impact strength test of FRC sisal fiber effect strength test.

Published: February 2021

Abstract
The unwanted disturbance in the form of vibration causes damages to the components produced and reduces the efficiency of the machine. Analysing and controlling the vibration is very important for moving machines. The working principle of 3D printer is Additive Manufacturing Technique. Thus, for a minute vibration the observable defects are produced. So, it is necessary to analyse the vibrations of the 3D printer. To analyse a machine, it is important to know about the motions produced by the machine, then suitable sensors must be chosen to measure those motions. The condition of the machine can be found using sensor measurement values. A 3D printer produces three types of motions such as point to point motion, zigzag motion and continuous motion. The vibration produced during each of these motions is monitored using the conventional accelerometer, micro accelerometer and the micro flown sensor. The values of micro accelerometer are acquired using Arduino and NI – cDAQ9174. The results from each of these sensors are analysed and compared. From the results, it is clear that during the continuous motion the vibration is very less since it is observed during the soft edges of the components. The vibration is maximum and rhythmic during the zigzag motion due to sudden acceleration and deceleration. The point to point motion is produced while using the support material.
