In this paper, we have proposed an analytical body (breast-tissue) propagation model in terms of scattering parameters towards the design goal of a suitable ultra-wide band, (UWB) transceiver for early breast tumor detection. The scattering parameters are... see more

The system based on ultra-wide band (UWB) signals was employed for qualitative estimation of attenuating, reflecting and polarizing properties of conductive fabrics, capable to prevent local static charge accumulation. Pulsed excitation of triangle monopo... see more

Pulsed excitation of small size monopole antennas for generating wideband electromagnetic pulses was used. The monopoles were excited by electrical pulses having rise times of 600 ps, 200 ps, 70 ps and voltages 100 V, 15 V, and 0.... see more

Ultra-wideband (UWB) is the promising technology for localization of the objects behind the walls. Recent terrorist activities and law-enforcement situations underscore the need for effective through-wall detection. The approval of UWB technology made by ... see more

Life sign detection is important in many applications, such as locating disaster victims. This can be difficult in low signal to noise ratio (SNR) and through-wall conditions. This paper considers life sign detection using an impulse ultra-wideband (UWB) ... see more

Focused on solving the problem of adherence to the skin and the quality of the bioelectrical recordings, new devices that have emerged such as tattoo electrodes and flexible electronics, which prove to be a novel and viable technology, capable of improvin... see more

In the digital age struggling with the pandemic, theatres strive to gain new and retain old audiences by providing user experiences online. Information about events, electronic ticket purchasing, and live streaming require improved website functionality, ... see more

This study explores the market demand for conference interpreting in South Korea by exploring the signals that users perceive as important for professional conference interpreting services. The findings were derived from a questionnaire-based survey of 10... see more
