Traditional high-gain antennas, like parabolic reflectors and phased arrays, are challenging to implement on small satellites (SmallSats) due to their reduced volume when stowed for launch. Therefore, a deployable volume-efficient Miura-ori (VEMO) re

A novel 1-D beam-steerable reflectarray antenna (RA) is proposed for the ${\text{K}}_{u}$ -band. The RA aperture consists of $24\times48$ variable size square patch elements printed on a flexible plastic substrate. The aperture is wrapped around two

In this paper, a novel deployable flat panel reflectarray antenna (RA) is designed on an origami folding pattern for Small Satellite applications. The RA aperture deploys into a hexagonal geometry that achieves an aperture efficiency of a least 60%,

Robust Speech Recognition and Understanding
In most of the practical applications of Automatic Speech Recognition (ASR), the input speech is contaminated by a background noise. This strongly degrades the performance of speech recognizers (Gong, 1995; Cole et al., 1995; Torre et al., 2000). The
