This paper proposes a method for determining the optimal phase difference between transmitter and receiver coils for suppressing leakage magnetic field in wireless power transfer (WPT) systems. As the power level of WPT systems increases, the leakage in the magnetic field also increases. As a result, the possibility of electromagnetic field (EMF) or electromagnetic interference (EMI) issues also increases. There are various shielding methods for reducing leakage magnetic field, but all the methods need additional materials or power sources. In contrast, the proposed method can suppress leakage magnetic field by determining the phase difference between TX and RX coils current without additional materials. So, the proposed method also can reduce the weight and cost of the WPT systems. © 2024 IEEE.

In this study, spike-timing-dependent-plasticity (STDP) was reproduced in devices fabricated using GTO (Ga-Sn-O). GTO was fabricated by sputtering, and the performance of the device was confirmed by I-V characteristics. The previous experiments were performed with a 1Hz voltage waveform, but this time, a 1kHz voltage waveform was used to investigate the possibility of high-speed learning. The experimental results showed a symmetric STDP, indicating the possibility of high-speed learning. © 2024 FTFMD.

Jointly modeling the dependence of injury severity and crash size involved in motorcycle crashes in Cambodia using a copula-based approach

Escalating motorcycle crashes present a significant challenge due to the increase in motorcycle registrations and the corresponding increase in mortality rates. This issue is particularly acute in Cambodia, where motorcycles are the primary mode of transportation. In the analysis of motorcycle crashes, two key measures of severity are injury severity and crash size, notably the number of injuries. Typically, these indicators are analyzed independently to understand the impact and consequences of motorcycle accidents. Nevertheless, it is critical to recognize that both observed and unobserved factors may concurrently affect these crash indicators, indicating a possible interrelationship between injury severity and motorcycle crash size. Neglecting the joint occurrence of these variables can result in biased and incorrect parameter estimation. This research contributes to the existing body of knowledge by simultaneously analyzing the factors influencing both injury severity and motorcycle crash size. This approach further distinguishes itself by considering the interdependence between these two results utilizing a copula-based approach. Six models based on copulas were developed using the ordered logit model, which was designed to capture the ordinal nature of injury severity and crash size. By analyzing motorcycle crash data from 2016 in Cambodia, the Frank copula framework was identified as the most effective among the five approaches. The findings revealed that factors such as motorcycle-to-pedestrian collisions, head-on collisions, X junctions, and national roads significantly increase both motorcyclist injury severity and crash size. These insights are valuable for policymakers in formulating targeted strategies to improve motorcycle safety within transportation systems.

In this study, reducing the sidewall width of the 1200 V 4H-SiC planar power Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) by 6.9% increases the input capacitance, C_iss, by approximately 6%, which is contributed by the increase of 13.5% in Q_GS directly. In order to increase the accuracy of calculation and dynamic characteristics, the equation of C_iss,sp might be counted in the sidewall capacitance, C_swall, when the width is different from the interlayer dielectric thickness on the top of the gate. Then, the modified calculation result of 7% is almost consistent with the measured result of 6% and simulation result of 6.8% for C_iss,sp. In addition, the poly gate thickness between 400 nm and 800 nm can contribute extra change in C_iss,sp by 2-3% as well. Because of the reduction in the sidewall width, the die size is also reduced. The specific-on resistance is decreased by 17%, while exhibiting no significant change in reverse breakdown voltage. IEEE

In the past three decades, Gallium Arsenide (GaAs) wafers have served as the standard substrates for vertical-cavity surface-emitting lasers (VCSELs) emitting at infrared wavelengths. However, recent attention has shifted towards Germanium (Ge) substrates for long-wavelength VCSELs epitaxial growth. Ge substrates offer several significant advantages over traditional GaAs substrates, including more lattice matching to VCSEL’s distributed Bragg reflectors (DBRs), zero etch pit density (EPD), and reduced wafer bow and warp, which contribute to higher yield and reliability in VCSEL mass production. This study presents the fabrication and characterization of 940 nm high-speed oxide-confined VCSELs on 330 µm Ge substrates. The VCSELs achieve a maximum small-signal modulation bandwidth exceeding 17.5 GHz at temperatures up to 75°C. Furthermore, the Ge-based VCSELs enable successful 53.125 Gbps data transmission at both 25°C and 75°C, with transmitter dispersion and eye closure quaternary (TDECQ) penalties of 1.36 dB and 2.8 dB, respectively. © 2025 SPIE.
