“…Finally, the development process for these types of systems will be evaluated using a wireless cyber-physical simulator. Razfar et al [5] designed a network to be used in rocket delivery launch vehicles in real-time considering the delay of the network from the environment and the noise thus proposing a system that gathers acceleration information from multiple sensors relying on the orientation of the rocket back the system. These factors analysis was done using an OPNET simulator to understand the sensor's performance.…”

In this paper, we present a real-time optimized fuzzy fuzzy proportional integral derivative (FPID)-controlled wireless networked system for a high-torque direct current (DC) motor. The main challenge faced by such systems is the delay in the wireless networked control system (WNCS). We employed a powerful FPID controller tuned using particle swarm optimization (PSO) technique to compensate for the delay. The system is tested on a network using the TrueTime simulator with different parameters. The results show that the system exhibits a very stable response, with the FPID controller compensating for the delay effectively. Increasing the number of nodes negatively impacts the system's performance, resulting in higher overshoot, longer settling time, and longer rise time. Moreover, the choice of bandwidth share and sampling time significantly affects the system's stability and real-time response. The use of transmission control protocol/internet protocol (TCP/IP) or user datagram protocol (UDP) protocols with Node MCU is necessary to transfer data from the Arduino Microcontroller to MATLAB, as MATLAB TrueTime simulator does not support direct serial communication. In conclusion, this study highlights valuable insights into the performance of the proposed system, demonstrating the need for further improvements in the system's design and control algorithms to achieve stable operation.

“…The comprehensive implementation of quality education marks the beginning of the reform of science education. The important goal of the reform is to change the traditional classroom teaching and learning methods, change the attitude change of students from passive acceptance of knowledge to active learning knowledge, and advocate students to spontaneously integrate into knowledge learning, and advocate that "student through self-practice [4][5], constantly improve inquiry and Innovative awareness, learning the methods of scientific research, and developing the ability to use knowledge comprehensively." Therefore, the quality education will be further promoted.…”

In this paper, Intelligent sensors are used in college ping-pong teaching. The use of intelligent sensor-assisted teaching can effectively stimulate students' interest in learning and improve learning initiative. At the same time, combined with data fusion wearable technology to monitor sports conditions The use of intelligent sensor-assisted teaching plays an active role in the application and mastery of student ping -pong techniques, and the improvement of basic physical quality is not significant. The use of intelligent sensor-assisted teaching can form a continuous guidance with the improvement of students' ping-pong technical level, which is conducive to maintaining the enthusiasm of students to learn ping-pong for a long time and establishing a sense of lifelong participation in ping-pong.

Face Recognition techniques have been rising rapidly over past few decades and gaining attraction in many security systems. Several methodologies are proposed to provide excellent results in face detection. Sensing technology enables several applications such as transportation, healthcare and security. Video surveillance systems trace and identify moving objects. Wireless Sensor networks are used to monitor remote areas and can be applied to monitor a facility by considering each camera as sensor nodes. Cameras are used as nodes in a wireless sensor network with a central server or a gateway node for all the monitoring and analysis of the information retrieved from the nodes. Identification and authentication of users in any organization is quite difficult due to high movement. Face recognition can be used detect faces and identify them continuously in a video feed which can be deployed to continuously monitor an area. Feeding from camera to base station uses Multi-task Cascaded Convolutional Neural Networks (MCTNN) and FaceNet algorithms for face recognition. Further information about the person is sent to all the end-user nodes present in the wireless network. This approach has been implemented and evaluated on a prototype wired camera network called FaceNet to monitor a network and provide security. A method for tracking people in 2D world coordinates and acquiring canonical frontal face images that fits the sensor network paradigm. The approach evaluates and demonstrates the tasking algorithm in action on data acquired from the FaceNet camera network.
