Abstract
Accidents are one of the major reasons for loss of life. Many numbers of deaths occur due to road accidents. Passenger safety acts as the most important parameter. Carelessness is the first and foremost reason for the major accidents. This paper makes us to understand the cause of accidents, especially the side sweep accidents which occur in multi-lane highways. Side-sweep accidents acts as the major reason for death which occur due to accidents. This is when the driver wants to change the lane at the same time the other driver or vehicle obstructs the road within the same lane. Our objective is to know and simulate the different kind factors that have an effect on the chance of side sweep accidents. As an example, we all know that blind spots, components of the road that don’t seem to be visible to the driving force directly or through the rear-view mirrors. Similarly, the frequency produced with that a driver gives a glance to his rear-view mirrors before deciding to change the lane affects the chance of the accident. Even there is an intuition that may cause side-sweep accidents are additional possible if there’s a big distinction within the velocities of the vehicle and also the targeted lanes. There are a lot of factors that may cut back the chance of the accident: as an example, the sign of the lane change by the driving force will alert the near vehicles concerning the lane change, and that they will change their behaviors as if no accidents or commotion can happen.

Abstract
The significance of water rationing has increased over the past few decades. It is hard to estimate level of water in tanks manually. When the water tank is full, the client may not realise the condition that the motor is turned ON which leads to water wastage. To tackle the issues related with the water tank, the water level pointer and regulator framework are utilized. The water level can likewise be tried utilizing a sensor, so the siphon consequently turns ON if the water goes down. The proposed system can even notify clients about the damages in the tank.

Abstract
The Diyanqinamu Mo deposit in Dong Ujimqin Banner of Inner Mongolia is a large deposit. In this study, hydrothermal activity is divided into five stages: quartz - potassium feldspar - fluorite, quartz - muscovite, epidote - magnetite, chlorite - carbonate – pyritization, and argillization. The results show that early exsolved fluid has the characteristic of high temperature (up to 470°C), high oxygen fugacity, and Fe- and sulfide-rich in daughter minerals. LA-ICP-MS analysis of individual fluid inclusion exhibit early fluid is rich in W, Mo, Pb, Zn, Fe, Mn, As, Ag, Sn, and rare earth elements of La, Ce. The ore-forming fluids are NaCl-H2O system and contain gases CO2 and a small amount of H2 and N2. In general, the ore-forming fluids evolved from high temperature (340 °C - 470°C) with high salinity (up to 63.9 wt%NaCl equiv) to low temperature (189 °C - 202°C) with low salinity (as low as 0.18 wt% NaCl equiv). The ore-bearing fluid comes from the exsolution of the volatile-rich magma, and hydrothermal fluid boiling result from the drop of the pressure may have led to Mo precipitation. Based on the alteration, mineralization, and fluid characteristics, the Diyanqinamu Mo deposit is a porphyry deposit related to magmatic activity in Yanshanian.

The alleviation of terrain pollution: A web-based Android App contributing to terrain recovery
Authors: Tao Make , Liu Qiwei 
Published: July 2021

Abstract
To present the terrain’s pollution circumstances nationwide more directly and contribute to our further recovery solutions, we design an Android app to provide convenience for both clients and regulators. For clients who are using their land and want to find solutions for their possibly polluted land, our app can visualize their land information and they can submit recovery request. And for regulators who design solutions, our database can visualize all the requests for recovery and help them decide the most urgent request. In our work, we first design the web front-end of our app on Android Studio (a platform for developing apps), which mainly consists of three parts, the register and login part1, the information altering part2 and the request submit part3. Part1 enables clients to register and login by entering their username and password, Part2 allows clients to update their land information in the database, Part3 can record each client’s request (consists of land location, request time and pollute-rate) and save it at the database in web back-end. Then, we use mysql to construct our database in the back-end. Our database contains three tables, table1 for user information (like the username, password), table2 for land information (like the land location, land moisture, land PH, land heavy metal amount), and table3 for recovery requests. Finally we use some functions in JSP (a programming language for dynamic web application) on IntelliJ IDEA (JetBrains program platform) to connect the front-end and back-end to exchange the information. After the designing work, we put our app into practice in lab condition. Most feedback are positive, but crush problems happen sometimes, which inspires us to make further optimization. Therefore, our system has a broad application prospect.

Abstract
3D reconstruction is a key technology for robots to explore unknown environments. The 3D model of the scene can be used to navigate the robot or used for scene segmentation. But when the scenes become larger or the features turns to rare, the frequently-used multi-scales matching and optimization algorithm of images and point cloud cannot work well. In this paper, we make the first attempt to split the 3D-reconstruction structure into 2 parts: pose estimation with the help of RGB images and reconstruction using poses from the aforementioned part and depth images from RGB-D cameras. All of these efforts are for accelerating the speed of pose estimation and promoting the precision of the reconstructed model, the results shows the proposed algorithm in the paper can do better than other reconstruction algorithms.

Abstract
As President Xi Jinping pointed out, “Throughout the history of world civilization, mankind has experienced the agricultural revolution, the industrial revolution and the information revolution.” With the rapid development of the information technology, we are living in a new era of digitization with the digital technology in rapid development, our way of life is being reconstructed by the Internet, and we are being more attracted by the spread of network information culture. In recent years, virtual reality technology has been deeply infiltrated into our lives, and this technology integrates the development results of the computer graphics technology, the computer simulation technology, the artificial intelligence, the sensing technology, the display technology, the network parallel processing and other technologies. The world is in accelerating digitization, so is the art world, with the emergence of the digital technologies highly associated with computers. Nowadays, the virtual reality technology has been applied in many literary and artistic fields, such as the VR immersion experience in games, the VR live game scenes, the VR films and the VR museums, and the emergence of the VR technology has given artists new artistic thinking and creative inspiration. For Chinese traditional art is an important part of the history of Chinese art development, we should vigorously protect and carry forward the traditional art, so as to avoid the disappearance of the traditional art. For this reason, we must conform to the trend of the times, change the old ideas, take advantage of the digital technology and the virtual reality VR, and keep pace with the times. The digital technology shouldn’t be excluded from representing the traditional art as a new development medium and method. Taking the Chinese traditional frescoes of Mogao Grottoes in Dunhuang as an example, this paper tries to discuss how the VR technology is used to digitally re-present the Chinese traditional art for communication.

Published: July 2021

Abstract
Proposition and qualification of an eco-friendly gas mixture of Ar(5%):CO2(60%): N2(35%) for operating Resistive Plate Chambers of INO-ICAL experiment in avalanche mode is the soul of this work. The detector efficiency and streamer probability for the proposed mixture have been simulated using a hydrodynamic model developed by us. Efficacy of the mixture has been studied by comparing the simulated results to available experimental data for the standard gas mixture of

R134a(95.2%):i-C4H10(4.5%):SF6(0.3%) to be used in INO-ICAL,
as well as the same observables measured for other eco-friendly hydrofluoroolefin (HFO1234ze)-based potential replacements. To reduce the streamer probability of the proposed argon-based gas mixture at higher voltages, the usual practice of adding a small amount of electronegative gas SF6 has been tested. An alternative approach of lowering electronic threshold has been investigated as well for the same purpose.
Impacts of wildfire and landscape factors on organic soil properties in Arctic tussock tundra
Authors: He Jiaying , Chen Dong , Jenkins Liza , Loboda Tatiana V 
Published: July 2021

Abstract
Tundra ecosystems contain some of the largest stores of soil organic carbon among all biomes worldwide. Wildfire, the primary disturbance agent in Arctic tundra, is likely to impact soil properties in ways that enable carbon release and modify ecosystem functioning more broadly through impacts on organic soils, based on evidence from a recent extreme Anaktuvuk River Fire (ARF). However, comparatively little is known about the long-term impacts of typical tundra fires that are short-lived and transient. Here we quantitatively investigated how these transient tundra fires and other landscape factors affected organic soil properties, including soil organic layer (SOL) thickness, soil temperature, and soil moisture, in the tussock tundra. We examined extensive field observations collected from nearly 200 plots across a wide range of fire-impacted tundra regions in AK within the scope of NASA’s Arctic Boreal Vulnerability Experiment. We found an overall shallower SOL in our field regions (∼15 cm on average) compared to areas with no known fire record or the ARF (∼20 cm or thicker), suggesting that estimations based on evidence from the extreme ARF event could result in gross overestimation of soil organic carbon (SOC) stock and fire impacts across the tundra. Typical tundra fires could be too short-lived to result in substantial SOL consumption and yield less robust results of SOL and carbon storage. Yet, repeated fires may amount to a larger amount of SOC loss than one single severe burning. As expected, our study showed that wildfire could affect soil moisture and temperature in the tussock tundra over decades after the fire, with drier and warmer soils found to be associated with more frequent and severe burnings. Soil temperature was also associated with vegetation cover and air temperature.

Published: July 2021

Abstract
This paper presents a pilot protection method for UHV transmission lines based on negative sequence impedance angle, which can reflect the total fault type. In this method, the memory function of microprocessor is used to extract window data of one cycle for delay processing. Meanwhile, the variable is introduced to make artificial asymmetric fault and produce negative sequence component, which makes the negative sequence admittance angle discriminator applicable to all types of short circuit faults. Based on PSCAD / EMTDC, a 1000 kV transmission line and its fault model are built. At the same time, a large number of line simulation are carried out. It is verified that the method can reflect different fault conditions and basically meet the requirements of UHV line relay protection.
