In this paper, a new improved particle swarm optimization (IPSO) was proposed to process the global path planning in a static underwater environment for UUV. Firstly, the path planning principle for UUV was established, in which three cost functions, path length, exclusion potential field between the UUV and obstacle, and attraction potential field between UUV and destination, were considered and developed as an optimization objective. Then, on the basis of analysis traditional particle swarm optimization (PSO), the time-varying acceleration coefficients and slowly varying function were employed to improve performance of PSO, time-varying acceleration coefficients was utilized to balance the local optimum and global optimum, and slowly varying function was introduced into the updating formula of PSO to expand search space and maintain particle diversity. Finally, numerical simulations verify that, the proposed approach can fulfill path planning problems for UUN successfully.","PeriodicalId":387853,"journal":{"name":"Int. J.

The education sector is the particular sector which has been getting the influence to implement more advanced teaching methods, and this can be seen through the application of the monitoring system, remote control, and even data acquisition through the Internet. Therefore, this study demonstrates the development of the interactive system via the Internet for the remote access to the equipment known as LD-Didactic temperature system which is used in the laboratory. This particular system is developed using an Arduino-Espresso8266 and LabVIEW platform which is integrated with Blynk software in order to remotely control the Proportional, Integral, and Derivative (PID) setting. Furthermore, the proposed framework is specifically focused on the PID temperature control system, which allows students to learn and simulate the concept of the control scheme by adjusting suitable parameter gains. Moreover, the system evaluation demonstrates the functionality and ability of direct controlling, monitoring, and tracking in order to achieve the targeted temperature control. These three strategies ensure the reproducibility of the experiment for the implementation in different systems. Last but not least, the designed system illustrates that full integration of the system with the internet platform provides students with the underlying knowledge of fundamentals, graphic visualization, and simulation practices. These will subsequently facilitate the learning process of the students.","PeriodicalId":387853,"journal":{"name":"Int. J.

However, certain vital components of engineering education, such as laboratory work and hands-on practices, are harder to conduct online. Understanding how technology can help offering such components online can impact the quality of online education a great deal. The goal of this study is to improve the effectiveness of online courses in engineering. Particularly, we aim to transform some of the hands-on practices that are fundamental for engineering education into online setting. We first explored existing literature and found that real-time experimentation can be carried out with the help of online modules. We then designed two simulations for a fluid mechanics lab. We expect these simulations to be used to support teaching and evaluation of fluid mechanics through various assignments that utilize these simulations. This study surveys how online modules have been studied in effort to relax the time and location constraints of in-class education. Drawing upon the literature review it proposes a novel approach to incorporate simulations to ground learning of abstract concepts such as buoyancy.","PeriodicalId":387853,"journal":{"name":"Int. J.

Under certain application conditions, Free Space Optical (FSO) communication can effectively reduce system energy consumption. Combining the need of the short-distance communication in the cooperative control of the mobile robot, this paper focuses on the study for the infrared FSO communication method and devices. Eight infrared-transmitting and receiving modules with the angular spacing 45° were deployed to realize the omnidirectional communication. The systematic measurement shows that the designed communication system can effectively carry out data transmission within a distance of 14 meters when the bit error ratio (BER) is 0%. Through the link budget analysis, the theoretical transmission distance of the design system is about 24 meters, only accounting for 60% of the communication module data manual, and the BER rises rapidly as the distance increases. The analysis of the oscilloscope observation results indicates that due to the attenuation caused by each medium (mainly moisture, dust, etc.) in the propagation path, the BER rapidly increases when the distance increases. Therefore, based on the test results, this system is applicable for constructing a short-distance wireless sensor network to meet the needs of cooperative control of mobile robots, without involving the complicated pointing process.","PeriodicalId":387853,"journal":{"name":"Int.
