Vibration-based structural health monitoring (SHM) is essential for evaluating structural integrity. Traditional methods using contact vibration sensors like accelerometers have limitations in accessibility, coverage, and impact on structural dynamic

Abstract High-quality medical ultrasound imaging is definitely concerning motion blur, while medical image analysis requires motionless and accurate data acquired by sonographers. The main idea of this paper is to establish some motion blur invariant

In this paper, a new recursive structure based on the convolution model of discrete cosine transform (DCT) for designing of a finite impulse response (FIR) digital filter is proposed. In our derivation, we start with the convolution model of DCT-II t

We propose a single negative metamaterial (MTM)-based hollow-core fiber with multilayer cladding employing zero-effective-phase bandgap for optical confinement in this paper. The cladding is formed from a ternary 1-D photonic crystal (T-1DPC) unit ce

We present two designs of all-solid photonic bandgap fiber (PBGF) for higher order bandgap suppression to realize a unique transmission window for optical filtering purposes. These two approaches are based on either applying a low-refractive-index co

Different blur invariant descriptors have been proposed so far, which are either in the spatial domain or based on the properties available in the moment domain. In this paper, a frequency framework is proposed to develop blur invariant features that
