Research on the influence of physical activity on students’ academic achievements based on computer statistical software application
Authors: Li Lingshu , Lin Junwei 
Published: September 2020

Abstract
Due to the long-term concept of light sports in China, enthusiasm for physical activity is often misunderstood by parents as not expressing love. However, it has been proved that moderate to intense physical activity has a positive impact on academic performance. It is harmful to the health of young students to focus only on academic performance and ignore physical activity. In previous studies, there are long-term problems, such as insufficient experimental methods, lack of depth in content, focusing on pure physiological and psychological research, and lack of in-depth research on the relationship between sports activities and academic achievements. Therefore, this study will explore the relationship between physical activity and academic achievement, in order to change the public’s original prejudice against physical activity and highlight the importance of physical activity; According to different gender and age characteristics, this paper explores that students’ favorite sports have different effects on academic performance, and points out that there are intermediate variables between physical activity and academic achievement, such as aerobic endurance, stress, selective attention, sustained attention, attention shift, self-regulation ability. Physical activity can effectively promote the improvement of these variables, thus affecting academic performance, highlighting the equal status of sports disciplines and other disciplines.

System-level fault diagnosis method based on test model
Authors: Cong Wei , Hongkun Yu , Liu Jing 
Published: September 2020

Abstract
Aiming at the problems of many test states and uncertain test results in system-level fault diagnosis, a system-level fault diagnosis method based on test model is proposed. This method first divides the system nodes into multiple regions, then hierarchically organizes the regions, and implements a top-down hierarchical structure through the control nodes. On this basis, the guide words are used to describe system-level failure modes, formulate centralized test rules, and use data flows to identify failure modes caused by fault propagation and fault mutation, which reduces the state of fault testing and improves the accuracy of fault diagnosis. The example analysis shows that the method in this paper can meet the needs of system-level fault diagnosis, and has practical application value for shortening the time of system fault determination and improving the accuracy of troubleshooting.

Abstract
With the development of urbanization and industrialization, the excessive use of metals leads to a sharp decrease in soil resources. Funan River runs through the whole urban area of Chengdu, and the surrounding population density is large, and environmental governance needs exist all the year round. It is of great significance to test the soil heavy metal content in this area. Under current environmental pollution, heavy metals mainly refer to biotoxic materials such as lead, cadmium, mercury and chromium, which are widely distributed in the atmosphere, water, soil and other substances in nature. They will react with proteins and enzymes in the human body, thus losing their original activities and even causing chronic poisoning. In this paper, reasonable sampling, sample treatment, X-ray fluorescence analysis and other methods were carried out for the surface soil along the Funan River, and the quantitative analysis of heavy metals was carried out. Results show that the heavy metal content of surface soil Chengdu Funan river coast are not more than the soil environment quality standard “regulation of the secondary standard, however, As, Cu and Zinc are found in the experiment of different degrees of pollution, including the As affected by natural factors, pollution is not obvious, the Cu and Zn pollution is more obvious, and concentrated in the industrial zone, highway interchange, namely industrial pollution and traffic pollution are more serious.

Authors: Wu Liyun 
Published: September 2020

Abstract
This paper first analyzes the current obstacles of English writing and teaching under the traditional writing teaching model. Then based on constructivism and input-out theory, relying on Iwrite, we conducted a one-year experimental teaching. The experimental class adopts the online and offline hybrid writing teaching based on Iwrite, while only traditional offline teaching is adopted in control class. By comparing the results of pretest and post-test, students’ scores of the experimental class increased from 37.3 to 70.4, which is a big improvement in contrast to the rise from 35.3 to 56.5 in control class. Additionally, on the one hand, Iwrite platform can provide real-time feedback so that students can make modifications in time to practice writing many times. On the other hand, teachers can design targeted teaching based on statistics of mistakes in students’ writing from Iwrite. Therefore, the author proposes that it is essential to establish the mixed model of online and offline English writing teaching.

Abstract
Human spine curvature data are required to detect spinal deformity/diagnose irregular spine curvature. The shape of the spine assisting for the flexibility and weight distribution of the body. Around the world, many countries have started collecting spine curvature data for more than five decades; however, India lacks in this field. Few countries have also developed various instruments to gather spine curvature data; on the other hand, they still seem inaccessible to Indian markets. A device which can collect the data is very much required as it has application in vast fields like product development on ergonomics principles. This study developed an instrument (simple and low cost) to measure coordinates of spine curvature. A wooden specimen (resembles human spine shape) was designed with various angles to validate the measurement accuracy of the developed instrument. The selected curves of the template were measured using three machines, including CMM machine, FARO arm machine, and developed device. T-Test confirms that there was no significant difference in the measured curvature data among instruments. The error percentage was 2.57 % (maximum).

Abstract
The most commonly found disease in aged people which can be dangerous and which affects the condition of an individual’s life is disc degenerative disease. The shift in the anterior load-bearing column was caused by the disc height changes in posterior side which could have adverse effects on posterior column. The lack of symptoms at early stages makes the identification of disc degenerative disease difficult but once identified, the treatment actions should be taken at right time. Biomechanical literature gives a static morphology of the FE models of cervical spine. An upcoming tendency in the current day medical practice is the use of personalized medicines and the predicting capabilities of this trend gets affected by not taking into account morphology as a model parameter. Finite element analysis is used to find the effect of variations in morphology of spine, intervertebral disc height, slope of facet joint, process height of articular facet joint and segment size was parametrized. Finite element study was done on vertebral rotation variations and ligamental forces. Some of the most important morphological variations found in the anatomy were disc segmental size & height and body depth. The estimation of ROM and calculation of impact loads were found to be the key elements in the examination of degeneration of discs. Nonetheless there are risks involved in the extensive use of instruments for direct measurement of range of motion. Fem models of the lower cervical spine are derived from a CT scan with dissimilar elements and then quality of these models is evaluated with the help of mesh element-related metrics. The range of motion values are then compared with the literature studies and the model with good mesh standard are used for future examination process. The individual components of spine are subjected to different types of loading situations and the stresses developed on them need to studied. The results gained from the finite element model helps us to plot stresses of subjects obtained from the respective lifestyles can benefit surgeons to suggest treatment actions.

Abstract
Most of the cities in India offer auto-rickshaw services for short and large distances at an economical price. Yet there is little importance given to its study provided that there is a lot of scope to improve its aerodynamic efficiency. The objective of this work is to carry out numerical analysis to predict the aerodynamic characteristics of the vehicle. This numerical study is carried out using CFD software ANSYS-Fluent by solving Reynolds Averaged Navier Stokes equations with a realizable K-ℰ turbulence model via first-order schemes. The results obtained indicate the flow field variation in terms of pressure and velocity around the bluff body. This would also give an understanding of flow physics for further improvement in aerodynamic forces.

Published: September 2020

Abstract
The latest developments in hardware and software for laser-based flow diagnostics enable the investigation of complex flow phenomena under enclosed, high-temperature and even pressurized conditions. However, the successful application of a velocimetry technique strongly depends on the presence of appropriate light-scattering tracer particles (seeding) in the flow. In this study, the design and development of a Seeding Generator is effectively carried out with perfect measurements considering the flow characteristics. Compressed air testing was done based on the laser sheet visualization and the flow field was visualized. The results show that the fabricated seeding generator will be able to supply seeding particles for flows from subsonic to supersonic regimes.

Published: September 2020

Abstract
This article presents the design, fabrication and characterisation of an elastomeric flexible and stretchable strain sensor using a variable resistance fabric. This provides a viable alternative to the microfluid and nanoparticle based flexible strain sensors involving complex fabrication techniques. A nylon-spandex based stretchable fabric serves as the sensing element which is in turn embedded in an elastomeric substrate. The fabricated sensor is experimentally characterised for determining the linearity, hysteresis, stretchability and gauge factor. The Finite Element Method based simulations to predict the operational force range of the sensor corresponding to its strain sensing range has been validated with the experimental results. These sensors have a wide range of potential applications in the constantly developing field of compliant robotics and mechanisms. In future works, these sensors will be utilized in the biomechanical analysis of human movements to track the various joint parameters.

Published: September 2020

Abstract
Motorcycles are undoubtedly heavy, which commonly poses a problem when erecting the bike onto conventional double foot kick stands as well as it seems difficult to lift the bikes. So, using side stands is better to handle while parking bike, but it makes severe injury if the stand is not released. Most of the street side accidents occur due to lagging in releasing the side stand. This work mainly aims in designing an intelligent mechanism that automatically lifts the side stand when the driver sits in the seat. By using this control system whose setup has the ignition switch, pressure sensor,relay switch, motor drive, dc motor all controlled by the Arduino uno board through the programming interface, when the ignition switch is turned on and when the person sits on the seat integrated with spring, the spring compresses and the signals the motor to turn on and hence the stand slides up. When the ignition switch is turned off and low pressure sensed the side stand automatically pulls out to withstand the two-wheeler.
