Current automatic vision systems face two major challenges: scalability and extreme variability of appearance. First, the computational time required to process an image typically scales linearly with the number of pixels in the image, therefore limiting the resolution of input images to thumbnail size. Second, variability in appearance and pose of the objects constitute a major hurdle for robu...

The Year 2022 marks 100 years since Leon Brillouin predicted and theoretically described the interaction of optical waves with acoustic in a medium. Accordingly, this resonant multi-wave is referred to as scattering. Today, scattering has found multitude applications, ranging from microscopy biological tissue, remote sensing over many kilometers, signal processing compact photonic integrated ci...

A multilevel inverter is capable of generating high-quality stepwise pseudo-sinusoidalvoltage with low THD , applicable to high-power and high-voltage systems. These types of topologiesmay require a large number of switches and power supplies. This leads to much cost, large size, andcomplicated control algorithms. Thus, newer topologies are being proposed to decrease the numberof power electron...

In this paper we describe an indexing, querying and browsing system for online images based on the PNG (Portable Network Graphics) image format and its ability to embed structured metadata within the image. First we describe a Java application which enables the computer-assisted generation and editing of Dublin Core-based metadata descriptions for digital images and the annotation of regions wi...

Two novel planar slotted-antennas (PSAs) are presented that exhibit good radiation characteristics at the UHF-SHF bands. The proposed antennas are constructed using metamaterial unit-cells constituted from capacitive slots etched in the radiating patch and grounded spiral shaped inductive stubs. The proposed PSA design is fabricated on a commercially available dielectric substrate, i.e. Rogers ...

OBJECTIVE Asymmetrical skull deformity is frequently seen in children with cerebral palsy, and may contribute to postural abnormalities and deformities. The aim of this cross-sectional- survey was to determine the frequency of asymmetrical skull deformity and its correlation with clinical parameters. METHODS A 10-item checklist for asymmetrical skull deformity, postural abnormalities, and def...
