A Modeling Method for Small Packing Particles in Electromagnetic Simulation

open access: yesInternational Journal of Antennas and Propagation, 2016
A modeling method for small packing particles is proposed in this paper, especially for the application of the electromagnetic simulation. This method is able to model random distributed and mutual-contacted packing particles efficiently and accurately ...

Substrate Integrated Waveguide Leaky-Wave Antenna Conforming to Conical Shape Surface

open access: yesInternational Journal of Antennas and Propagation, 2015
A conical conformal leaky-wave antenna based on substrate integrated waveguide (SIW) technology is proposed and demonstrated in this paper. This antenna conforms to a conical shape surface with the angle of 40°.

Tone Recognition of Pahari Language

open access: yesJournal of Communication and Cultural Trends, 2023
Pahari is an under-resourced, endangered, and undocumented tonal language, spoken in Pakistan Administered State of the Azad Jammu and Kashmir (AJK). Preliminary studies have established the notion, that the Pahari language has three discrete level tones;

Pitch Perception: Dissociating Frequency from Fundamental-Frequency Discrimination [PDF]

open access: yes, 2013
High-frequency pure tones (>6 kHz), which alone do not produce salient melodic pitch information, provide melodic pitch information when they form part of a harmonic complex tone with a lower fundamental frequency (F0). We explored this phenomenon in normal-hearing listeners by measuring F0 difference limens (F0DLs) for harmonic complex tones and pure ...
