Techniques for wireless energy harvesting (WEH) are being emerged as a fascinating set of solutions to extend the lifetime of energy-constrained wireless networks.They are commonly regarded as a key functional technique for almost perpetual communications.With the WEH technology, wireless devices are able to harvest energy from, e.g., different lig
The purpose of this work was to study bias error in acceleration-based transfer alignment, which is probably caused by cross-correlation between the dynamic lever-arm and the linear motion of a ship.A new prediction model for the cross-correlation-caused error is proposed in this paper.We adopt the Bernoulli-Euler Beam as a simplified ship hull-gir
Abstract Intra-pulse modulation recognition under negative signal-to-noise ratio (SNR) environment is a research challenge.This article presents a robust algorithm AFTER SUN SOOTHER for the recognition of 5 types of radar signals with large variation range in the signal parameters in low SNR using the combination of the Short-time Ramanujan Fourier
The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter (SolO) provides a unique opportunity to systematically perform stereoscopic X-ray observations of solar flares with current and upcoming X-ray missions at Capo Earth.These observations will produce the first reliable measurements of hard X-ray (HXR) directivity in decades,
Objectives The aim was to evaluate dentinal crack formation after root canal preparation with ProTaper Next system (PTN) with and without a glide path.Materials and Methods Forty-five mesial roots of mandibular first molars were selected.Fifteen teeth were left unprepared and served as controls.The experimental groups consist of mesiobuccal and mes
