Remote Probing System (RPS) is an innovative touchless semi-automatic probing system which make use of IoT, Robotics and Augmented Reality (AR) that aim to provide virtually control movement of oscilloscope probes to obtain signal integrity and waveform measurement. This solution allows remote access to perform validation and integrity test on platform that lack on availability. One of main features is 3-axis probing, which is X-axis (left and right movement), Y-axis (front and back movement), and Z-axis (up and down movement). This system supports up to 15kg of board weight with double-sided probing features without tangling the wires. In addition, an AR layout viewer will be used to overlay every aspect of a design directly onto the platform. It supports electronic design automation which also known as electronics computer-aided design and integrates with unified components search engines.

The fast-growing demand for renewable energy has stimulated the rapid development of semiconductor devices and power electronic converter technologies. The grid-connected inverter has turn out to be normal in any distributed generation system. LCL filter is commonly adopted to interconnect an inverter to a utility grid, owing to its parametric performance. However, the common issue regarding resonance frequency and design constraints complexity remains unsolved entirely. In this paper, a simple LCL filter design to address these issues is proposed. A ripple current minimization approach is adopted in the systematic design process to determine optimized reactive components' value and mitigate its resonance frequency. Design feasibility is simulated in the Matlab/Simulink environment and extensive experimental work was carried out to validated the results against the IEC61000-3-2 standards.

Recently, the development of DC long transmission line has been reconsidered as it emits less power loss as compared to AC power transmission line. The reason is because, the implementation of non-isolated converter in the system could omit the uses of transformer that contributes to the conversion loss. Besides, interleaving method is incorporated in the converter as a very high DC voltage is needed to be transmitted along the DC long transmission line. By applying such method, the output voltage ripple and output current ripple can be reduced. In this paper, modelling and simulating is done in MATLAB/Simulink for both interleaved and conventional boost converter with same switching frequency at 50 kHz. The results and analysis of both converters are based on Continuous Current Mode (CCM). The improvement of boost converter by using interleaving method can get a better voltage gain, reduced output voltage ripple as well as reduced output current ripple.

The internal defects of industrial components such as magnetic tiles seriously affect their performance. With the development of intelligent manufacturing technology, industrial manufacturing enterprises need an automatic method to efficiently and accurately detect the internal defects of magnetic tiles. In this paper, a signal pre-processing algorithm based on Empirical Mode Decomposition (EMD) and wavelets denoising is proposed for echo signals for defect detection. Then the variance curve and the adaptive processing method are used to locate the defects accurately. The experimental results show that the algorithm proposed in this paper can been successfully used in defect specimen with different transducer frequency, different defect size and different defect depth. Compared with the original B-scan image, and the internal defects of the specimen could be detected more prominently in enhanced B-scan image, and the accuracy of the defect depth could reach 98.76%, which is better than existing state of the art. Thus, the proposed method has been proved to be effective for optimizing ultrasonic B-mode scanning and accurately locating defects inside magnetic tiles.

This work suggests a five-level cascaded bidirectional converter for battery charger application. The proposed converter is presented in both Buck and Boost approaches. The proposed converter operates at 50-kHz linked with isolated high frequency and loaded by a battery via Buck/Boost switch. The five-level scheme applied the phase disposition system to generate the PWM signal. Besides, this converter can be widely utilized in high-power and medium-voltage applications. The proposed converter simulated in MATLAB/SIMULINK and selected results were adopted to prove the system validity. As a result, the state of charge SOC is decreasing and increasing in charging and discharging mode, respectively. The controller was designed to automatically detect the required mode of operation, buck, or boost, based on the sign of Iref. In general, the behavior of the simulated system results is in agreement with the theoretical part.

This paper proposes to design an enhanced grid to the vehicle (G2V) wireless battery charger using Single-Phase Matrix Converter (SPMC) circuit topology. The proposed circuit topology employed a single converter to perform direct AC to AC converter at the transmitting coil, thus reducing circuit complexity and power semiconductor losses. In this paper, the SPMC act as a direct AC to AC converter to convert the input supply voltage at 50 Hz into 20 kHz to meet the switching frequency operation of the Wireless Power Transfer (WPT) function. The high-frequency voltage at the output of the WPT circuit is then being rectified into DC form by using AC to DC converter. WPT technology is being used to remove the annoying wires of the conventional Electric Vehicles (EVs) charging system, thus improve the safety of the vehicle charging process by preventing any contact between the driver and the vehicle charging system. The proposed system uses the minimal circuit topology where the single SPMC circuit is used to replace the conventional two stages of AC-DC-AC converters. A computer simulation model of the proposed system using MATLAB/Simulink has been designed and modeled. The selected results are presented to verify the proposed circuit.

Applying visual recognition algorithms in surface defect detection has aroused increasing interest in industries. Despite the compelling speed advantages over manual detection, many algorithms fail to inspect defects from tail classes, especially where one defect dominates while the others have a few instances. One reason is that most of those computer vision models are proposed for class-balanced datasets while surface defects on industrial products often follow long-tail distributions. Existing studies alleviate this problem by simply adding synthetic data to the tail classes or manually adjusting weights. Herein, we propose: 1) a transformer embedded backbone structure to extract more representative features from the targets; 2) a 3-grids coordinate loss for predicting targets with multi-scale to reduce the targets miss rate. Our system can detect different kinds of surface defects at 125FPS, achieve 9.8% higher mAP and 3-22% higher AP of tail classes than YOLOv4 on long-tailed magnetic tiles datasets. Besides, our experiment on steel plates dataset shows that the effectiveness of our system is not limited to a certain industrial scenario, making it useful for a wide range of automated inspection tasks.

With the continuous development of science and technology, self-driving vehicles will surely change the nature of transportation and realize the automotive industry's transformation in the future. Compared with self-driving cars, self-driving buses are more efficient in carrying passengers and more environmentally friendly in terms of energy consumption. Therefore, it is speculated that in the future, self-driving buses will become more and more important. As a simulator for autonomous driving research, the CARLA simulator can help people accumulate experience in autonomous driving technology faster and safer. However, a shortcoming is that there is no modern bus model in the CARLA simulator. Consequently, people cannot simulate autonomous driving on buses or the scenarios interacting with buses. Therefore, we built a bus model in 3ds Max software and imported it into the CARLA to fill this gap. Our model, namely KIT bus, is proven to work in the CARLA by testing it with the autopilot simulation. The video demo is shown on our Youtube.
