We present a novel heuristic approach for pulse repetition interval (PRI) modulation recognition by identifying the temporal pattern based on a symbolic radar pulse train analysis. The analysis of the symbolization of radar pulse trains is presented as a metric for the ability to identify the temporal PRI modulation characteristic. The recognition approach developed based on a time series analysis technique has to transform the radar pulse trains into a corresponding sequence of symbols. We retain temporal information from transforming the time series of pulse trains through numerical computations. The PRI pattern is obtained for real-time monitoring, and then the modulation types are identified based on characteristics. The simulation results show that the proposed algorithm can effectively recognize the PRI modulation type of radar pulse trains.

Beyond Visual Line of Sight (BVLOS) operations are crucial for enabling the drone industry’s upcoming phase of UAV commercial acceleration. One of requirements to support BVLOS operations in UAV is mobile network with proper connectivity. In this study, the effect of UAV flight characteristic (altitude, attitude, and speed) to mobile network quality for UAV BVLOS operations will be analyzed. However, due to the time limitation of the publication, only preliminary results are presented. First, general technical framework including hardware, software, the data stream, and network coverage is described in the methodology. Then, a prototype UAV equips with Raspberry Pi and 4G connectivity is developed. A ground test is conducted to test functionality of the system. The preliminary result shows that the framework system functioning well in terms of transfer and receive data with the average latency 40 milliseconds. Next step, the flight test will be conducted to measure the effect of the UAV flight characteristics on the mobile network quality.

The loss management work is closely related to the line’s operation efficiency, the power enterprise’s economic benefits, and electricity consumption safety. However, the strange relationship between the household transformer leads to the inaccurate calculation of the line loss in the station area, thus hindering the line loss management work. Therefore, given the problems of large workload, high cost, and short timeliness of identification results in traditional manual inspection, line loss fluctuation data is used to screen abnormal users of household transformer relationships. Accurate compensation editing distance (ERP) is combined with the dynamic time warping algorithm (DTW) to calculate the similarity of the user voltage curve in the abnormal station area. The SOM clustering algorithm is used to update and identify the household transformer relationship in the abnormal station area. Finally, the correlation analysis and convolutional neural network algorithm are combined to analyze and verify the updated household transformer relationship by using the power outage correlation between the station area and users, which has a specific application value.

The automatic judgment of the object’s angle enhances the work efficiency of mechanical loading and unloading, which is necessary for the workflow of non-fixed placement. Therefore, we develop a method for judging object angles imported into various scenarios. First of all, we establish the model of each tool. Before the identification process, the proposed system improves the accuracy by adjusting the brightness and contrast. Then, the position and angle of the object are judged to transmit the result to the robotic arm for gripping. In addition, we find the best gripping point according to the boundary shape of the object to enhance the stability of the moving process so that the workpiece does not fall during the process. From experimental results, after the images are captured through the camera, we attempt to determine the object’s coordinates, angles, and clamping positions to improve the efficiency of the handling process. This design is implemented in various loading and unloading processes.

Visual impairment causes many inconveniences in people’s everyday activities such as traveling, socializing, or exercising. For those who are blind, maintaining a healthy and balanced lifestyle is exceedingly difficult. For instance, it is extremely challenging to participate in team sports such as basketball or football without visually locating the ball or the other players. For players with visual impairments to locate the ball with audio feedback during football matches, a customized ball equipped with sound devices is now required. Such settings, however, necessitate extremely silent settings and are challenging to implement for training or regular play. In this research, we suggest a wearable haptic display and interface design to improve football players with visual impairments’ target and player location tasks. We describe the haptic feedback design for players’ ball tracking and the system architecture facilitated by Internet of Things technology.

A CNC parameter optimization approach is presented to predict machining quality based on deep learning. The approach aims to optimize tracking error, contouring error, and cycle time simultaneously. CNC interpolator parameters including the limit of velocity, acceleration, jerk and corner tolerance are regarded as experimental factors. The standard test toolpath KANINO is adopted to collect signals of motion axes in various combinations of interpolation parameters. The back propagation neural network (BPNN) is utilized to establish the predicted model between the interpolation parameters and machining performance index. The parameter combination is optimized by the trained BPNN model with the non-dominated sorting genetic algorithm II (NSGA II). Finally, experimental validations are provided to demonstrate effectiveness of the proposed method in improvement of machining quality.

In this project, performance of bearing lubricant for wind turbine were analyzed. The experimental equipment includes fans, anemometers, generators, rectifiers and voltage stabilizers. carbon steel sheet is used as the wind turbine skeleton which was matched with the position of the lock hole of the bearing fixing seat, and is fixed and well-constructed. Material of blades was assembled using aluminum alloy and the fan was driven by a fixed air source in experiment. Power generation of wind turbine as well as vibration data of bearing of wind turbine were investigated. The vibration frequency spectrum of bearing was regularly measured under normal circumstances. Lubrication performance and power generation were investigated by comparison with two different lubrications. The experimental results can be obtained by checking the rotation speed and power generation efficiency of different greases. Though there was no obvious change in rotation speed and power generation, the RMS diagram of vibration spectrum shows a decreased trend. A simple test model using a fan motor was set up for vibration test. The rotation speed was increased in a specific formula of grease that compared with a general grease, which can also be read from the frequency spectrum in vibration test.

In this project, we develop a device to warn the elderly when they are unsteady and at a risk of falling, based on a low price IMU sensor. From our preliminary study we find that during the sway, the body vibrates violently in all frequencies. This is different from the body at stationary posture, where the vibration is small, or when a person moves in a regular manner where the body vibrates with some definite frequencies. From these results, it is possible to use the mean amplitude of the Fourier spectrum of the body acceleration to distinguish the vibration state of the body, which can be used in the warning system. We then designed the device using the low price MPU6050 sensor to measure the body acceleration. This device will be attached to the body (hip) for collecting the acceleration data. An ESP8266 board is used to collect and control the sensor operation. Another ESP8266 board is used to receive and send the data to a Raspberry Pi unit. All data transmission is performed wirelessly via ESP NOW protocol, which is a low power consumption 2.4GHz wireless communication with a data package of up to 250 bytes at a time with 100-200m transmission range, which cover the living space area of typical wearer. When the mean amplitude of Fourier spectrum is greater than the warning criteria, the Raspberry Pi will send a signal to the warning unit wirelessly through the ESP8266 board. There are 3 types of alarms in warning unit which are sound alarm, light alarm, and LCD display alarm. We have tested our system with many volunteers. The mean amplitude of Fourier spectrum in the steady, walking, and sway condition can be clearly distinguished. In all cases the state of risky from falling can be detected correctly. We are now in the process of maximizing the data sampling and analyzing time to make the falling prediction as fast as possible.
