This paper proposes the analysis of the material can be protected from transformer testing and presents a mathematical model of the power transformer. In this research, transformers were study in four protective materials, wood, rubber, glass and acrylic that are used in between the electric field measurement and the transformer. By simulating the test results of a transformer with a voltage of 230 kV. Computer-based simulation utilizing the finite element method (FEM) is exploited as a tool for visualizing electric fields distribution volume a power transformer. The simulation results showed that the material with the best protection against the electric field was wood insulation and the best installation location was a distance of 5 m from the transformer.

There is a need for an interface for the teleoperation of rescue robots that can be used with less training and reduces the mental burden. In recent years, numerous teleoperation interfaces for robots have been developed using commercially available VR headsets and VR controllers. In this study, to investigate the usefulness of VR interfaces in tasks involving both movement and manipulation, a VR interface capable of both movement and manipulation was proposed and validated by users in a door-opening task. The validation results confirm that operations using the VR interface contribute to a shorter working time with the manipulator compared to operations using the gamepad. Additionally, mental demand, temporal demand, and effort tended to be reduced in manipulator operation using the VR interface in the NASA-TLX mental workload assessment. However, the gamepad was also identified as a suitable input device for driving operations, and combining both operations or using them differently depending on the situation may reduce the operator's workload.

We present light extraction efficiency (LEE) improvement for InGaN red micro-light emitting diodes (micro-LEDs) of various sizes operating at low current densities. We compared the characteristics of micro-LEDs with indium tin oxide (ITO) transparent p-electrodes with conventional opaque metal p-electrodes. 50 µm × 50 µm micro-LEDs with ITO p-electrodes achieved a peak on-wafer external quantum efficiency (EQE) of 2.54% with an emission wavelength of 640 nm at a current density as low as 0.4 A/cm 2 . This represents a 1.18-fold improvement in peak EQE compared to devices with metal p-electrodes. Light ray tracing simulation confirmed that the ITO p-electrodes exhibit 1.18 times higher light escape than metal-based micro-LEDs, validating the role of enhanced light extraction. These findings provide valuable insights for advancing high-definition display and VR applications.

Lilies are popular in the global flower market, but consumers often lack information about specific varieties. To address this issue, this paper proposes a computer recognition platform based on the Vision Transformer (ViT) architecture. The proposed platform uses an improved vision transformer (ViT) architecture to classify different types of lilies, allowing consumers to access information and names of various Lilium species. The experimental results show that the proposed lily classification model achieved a 96.4% accuracy rate in classifying six lily species.

This paper presents an efficient reconfigurable parameterized convolutional neural network (CNN) accelerator designed for FPGA platforms. The core of the accelerator allows flexible adjustments of input channel parallelism (Pc) and convolution filter parallelism (Pn) to meet the needs of various CNN models, optimizing both resource utilization and computational efficiency. The architecture is applied specifically to infrared (IR) and visible light (VI) image fusion, enabling real-time processing on an FPGA with significantly reduced latency. Experimental results demonstrate that the accelerator reduces latency to 192 ms while maintaining high image quality, achieving efficient image fusion on the FPGA platform.
Purpose: Objective response detection (ORD) techniques assess if evoked potentials are embedded in the background electroencephalogram (EEG). If each technique gives its result, then it is necessary to check which tes...

This study presents a deep learning framework optimizing 3D clothing models for VR, using a CNN to significantly reduce the triangle count of models from DeepFashion3D and CAP-UDF datasets. Achieving a balance between efficiency and detail, it cuts triangle count from over 160,000 to below 4,000, maintaining high DPI. The approach automates optimization, promising scalability and efficiency in VR fashion, setting a foundation for future 3D content development, enhancing virtual garment realism and interactivity.
