Abstract
The earthquake is an emergency with low probability and high risk. Constructing a real earthquake disaster scene can be used for earthquake emergency exercises, and timely inspection of escape, self-rescue and mutual rescue, and government decision-making deficiencies. Conducting the earthquake exercises under realistic conditions is not easily realized. Compared to the previous methods, the method based on virtual simulations is considered as one of the best effective ways. In this study, we employ the virtual simulations to construct earthquake disaster scenarios. The disaster scenarios immerse people in a virtual environment, where they learn to respond to earthquakes. We demonstrated the system architecture and its components, adopted 3dMAX and virtual simulations to reconstruct the modeling and reproduction of the regional topography, the city and the roads, bridges, hospitals, and building collapses in disaster areas. Virtual reality technology is used to realize the construction of the virtual city. Tests show that the system has good stability and effect, and reached the target set by the system.

Published: February 2021

Abstract
Gravel materials are widely used in dam engineering in western China due to their excellent engineering characteristics such as high compaction density, high shear strength and strong water permeability. The compaction standard of gravel materials is evaluated by the relative density index. Therefore, after a reasonable compaction standard is determined, the next most critical link is the control of construction filling quality. Based on the results of field rolling tests, this paper analyzes the basic influence laws of gravel content, paving thickness, rolling times and water content on the compaction dry density and relative density of gravel materials, and studies the basic compaction characteristics of gravel materials, and determines the construction compaction parameters based on satisfying the design compaction standard. By controlling the gradation, rolling parameters and water content of dam construction gravel materials, the filling quality of dam construction can meet the design compaction standard, so as to ensure the safety and stability of dams.

Abstract
In recent years, viscous energy dissipation wall is widely used in China. In the case of a 5-story frame structure, the combination of viscous damping wall (VDW), buckling restrained brace (BRB) and (VDW + BRB) is used for seismic design. Under frequent earthquakes, (VDW + BRB) scheme has the best damping effect, which can effectively reduce the response of superstructure and greatly improve the seismic safety of building structures.

Published: February 2021

Abstract
Secondary lining cracking always occurs in existing tunnels when the tunnel passes through the weathered argillaceous siltstone layer, which seriously affects the safety of the tunnel. In order to study the mechanical properties of weathered argillaceous siltstone and the cracking law of the secondary lining, this study analyzes the relationship of accumulative plastic strain between the dynamic stress amplitude and static deviator stress, as well as the cracking law of the secondary lining of the sample. The results show that under cyclic loading, there are obvious accumulative plastic strain in weathered argillaceous siltstone; the bearing capacity of the secondary lining structure at the biased part shows an evident increase than that of others with cracking generating faster. The research results provide a reference for the safety and operation of the tunnel that runs through the weathered argillaceous siltstone layer.

Abstract
To maximize the effectiveness of solar energy systems installed on the ship, the panels need to be positioned on their optimal inclination angle. To determine this angle, information on hourly average solar radiation is required in addition to position and direction data. However, the amount of hourly solar radiation is not continuously measured in Indonesia. This study proposed a method to estimate the hourly solar radiation for any month. This is based on Artificial Neural Network (ANN) with the month and the hour required for the estimate and the previous daily average solar radiation as the input. The proposed ANN method was validated by comparing the estimation results with the measured hourly average solar radiation in Surabaya from May to July 2020. Its effectiveness was affirmed with the coefficient of determination (R2) of 0.983 or higher for each of the three observed months.

Abstract
Natuna Island is one of the small outer islands in Indonesia bordering Malaysia, Singapore, Thailand, Vietnam, and directly facing the South China Sea. Natuna seawaters have enormous potential fishery resources and one of the fishing areas used as a fishing activity for Indonesian and foreign fishermen. The potential also made illegal fishing practice rampant in Natuna seawaters and led to the Indonesian maritime security patrol being directed to Natuna seawaters to stop the illegal fishing process. The marine security patrol activities require high operational costs, and This can be minimized in several ways, particularly by knowing the points that can contain extensive fish resources, and the security patrols can be carried out directly at these points of location. To obtain information about these locations, map the potential fishing areas in Natuna seawaters for each period or monsoon. This study aims to apply remote sensing analysis to collect comprehensive information regarding strategic fishing areas prone to violations and security threats related to fishing activities based on monthly analyzes. The data used in this study were chlorophyll-a concentration and SST from MODIS level-3 with a resolution of 4 km from January to December 2019. SST and chlorophyll-a concentration data used pre-process analysis with SeaDas Software to ensure the data projection in the World Geodetic System (WGS) 84 format. The data processing stage uses ER Mapper software to project the distribution of SST and chlorophyll-a concentration into a contour. Post-processing data used ArcGIS software to determine crosses’ results on the SST contour and the combined chlorophyll-a concentration. Image data processing results show that the lowest fishing point on Natuna Island in August with 51 fishing points, and the highest fishing point on Natuna Island in February with 584 fishing points. The results showed that fishing points vulnerable to illegal fishing are mostly located in the northern part of Natuna Island. The fishing zone is mostly far from Natuna island’s coastal line. The results of this study indicate that the fishing area in the outer regions of Natuna Island needs to be increased in security and protection, especially in regions with a high level of fishing activity. This information is expected to become a reference for the authorities in the marine security sector in Natuna waters to take certain policies related to marine security patrols’ operational activities in Natuna waters, particularly in minimizing operational costs of marine security patrols in Natuna seawaters.

Abstract
The motivation for snake robots originates from natural snakes. Snakes show better versatility abilities and can move over basically any kind of landscape, including limited and restricted spaces. Like a snake, robot has an exceptionally expressed robot controller arm with the capacity of giving its own drive. Wheel-less, limbless secluded Snake-like robot (Snake robot) has superior capacities in flexibility and adoptability to nature in examination with the most haggled vehicles. Some helpful highlights of snake-like robots incorporate smaller size of the cross-sectional regions, steadiness, capacity to work in troublesome landscape, great footing, high redundancy and complete fixing of the inside systems. Our model consists of multiple links joined together to create propulsion on its own in a spatial environment. The first link (head) can have various configurations like camera, gripper, etc. This makes the snake robot ideal for search and rescue operation.

Abstract
The fast development of sensing element and wireless communication technologies has exaggerated the use of wireless sensors in environmental observance. The water consumption is rising day by day, as the water supplies for various social units and for industrial purposes is rising. And that is why surface water isn’t really capable of meeting water needs. This subterranean need for water has been misunderstood. This work is based on meeting the challenge of easily sorting the underground water with the aid of a robot. This robot based on Arduino Mega will examine the surface in relation to Wenner methodology to look for the existence of water body beneath the earth’s surface. It will define the location of underground water with respect to a GPS module connected to the Arduino. The location data obtained from the GPS module is used to record at that particular depth the exact location and volume of water present. This knowledge can help to map underground water in that geographical area.

Abstract
The robotic manipulators are nowadays used for many applications in the industries. This project involves the design and analysis of a six DOF manipulator for welding, pick and place application. We developed a robot in Solid Works and analysed it motion, load withstanding capacity and path traceability. However, design and analysis of a robot involves modelling of it forward and inverse kinematics. We modelled the forward and inverse kinematics by D-H parameters. The proposed model makes it possible to control the manipulator to achieve any reachable position and orientation in an unstructured environment. The inverse kinematics provided many possible combinations of angles for a single end effector position. A GUI was created in MATLAB for studying the forward and inverse kinematics of the robot. It gave results with precision of 0.2 cm. the load analysis also gave the maximum load it can withstand 200 KN without permanent deformation. The approach presented in this work can also be applicable to solve the kinematics problem of other similar kinds of robot manipulators.

Published: February 2021

Abstract
Drones of various types are currently in great demand because of their flexible applications to facilitate human life. At acceptable constant quality levels, they can perform tasks in a repetitive manner. A drone is intended and built in the current work to evaluate the area vulnerable to fire and its surface area at an altitude of 10 meters. In the event of a forest fire disaster, evaluating the impacted area is very complicated. This approach needs to be adaptable and easily controlled in order to solve it. Thus, both the manual and autopilot mode are built and controlled by a quad copter drone with an ardupilot, which drives the drone to the specified location. The drone is fed with the specification of the Global Positioning System ( GPS) and flies with the aid of an ardupilot to the spot. With the aid of a thermal imaging sensor, the drone senses the surface area with its captured image. With the aid of coding dumped in it, the image is sent to the base station and the vision building is achieved with the help of the thermal camera fitted in the front part of the drone and then it interacts with the base station where it is possible to view the surface area. This allows average individuals to recognize the region impacted by the tragedy and to predict the amount of impact they have made in a shorter period of time. Human interference is minimized by this detection method in the areas affected by fire with the extent of fire prediction.

AbstractInfrastructure development in a country depends on the development of road network. In a developing country like India construction of pavements forms the integral part of infrastructure development. The most common material used for the construction of pavements is hot mix asphalt (HMA). The demand for this material is very high and at the same time due to maintenance of pavements lot of used paving material is wasted. This paper deals with the characteristics of reusing the reclaimed materials as construction materials in the construction of pavements. Experimental investigations were conducted to study the properties of aggregate and bitumen that are reclaimed. The test results on the reclaimed material were conducted and it was found to be suitable to be reused for the pavement construction. Systematic proportioning of the reclaimed material with the virgin material was investigated and the results show that the reclaimed materials performed equally well as the virgin material. The cost analysis for using these recycled materials is also calculated, in order to highlight the advantage of using the recycled material.
