The dynamic performance test of a hard disk head is the most effective method of evaluating hard disk performance, but it must be conducted in a dust- and electrostatic discharge (ESD)-free envir ... Read More

In this paper, we analyze the guided-mode properties of negative curvature hollow-core fibers (NCHCFs) using a new algorithm derived from the vector boundary element method (VBEM). We present a n ... Read More

A 3D automatic sensing measurement system was developed to improve image processing technology for inspecting electronic parts. The developed system can automatically and rapidly measure a small ... Read More

In traditional medical ultrasound treatment, the doctor’s hand needs to take the ultrasonic scanner and move it around the wound location. In this study, the ultrasonic scanner is grasped by a ... Read More

Toward improving water pipe leakage detection, we use an ESP32 board, sensors, and Internet of Things (IoT) technology to achieve the flow rate detection and throttling of water. We use a Message ... Read More

For a blood pump, high shear stress and bearing wear produced by its high rotational speed are the major factors causing mechanical damage to blood cells inside the pump. To eliminate frictional ... Read More

Railway and highway traffic projects inevitably require a large number of tunnels to pass through hills or mountains due to the complex topographic conditions. Accordingly, tunnel construction in ... Read More

The development of technologies is changing the traditional concept of teaching and learning in classrooms. In particular, information technology (IT) courses are rapidly adopting such changes as ... Read More

We designed an injection molding process based on the product analysis of the cover of a motorcycle side mirror. The purpose is to develop a design for the injection molding of the product, which ... Read More

In this study, we used an e-beam evaporation method to deposit SiO2 and Ta2O5 single-layer films on glass substrates, then the extinction coefficients (k values) and refractive indices (n values) ... Read More

Emotional analysis in texts is one of the difficult problems in text feature extraction. Semantic information is not unique for a large number of text features, which increases the difference in ... Read More

We propose a passive patch antenna temperature sensor architecture consisting of a transceiver and a passive patch antenna temperature sensor made of RO3003 and Mg2SnO4 ceramic substrates, respec ... Read More

It is important to monitor the occurrence of cavitation in machines as it may damage them. Sensing technologies are used to monitor the occurrence of cavitation, but the mechanism of cavitation n ... Read More
