A Novel High-Performance Patch Radiator

A Novel Patch-Based Digital Signature

In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...

Direct-Radiator Loudspeaker Systems with High Bl *

Direct-radiator loudspeakers typically have a very low efficiency since the acoustic load on the diaphragm or cone is relatively low compared to the mechanical load, and in addition the driving mechanism of a voice coil is quite inefficient in converting electric energy into mechanical motion. The drivers have a magnetic structure that is deliberately kept mediocre so that the typical response ...

A Novel High-Performance Liquid Chromatography Method for Detection of Alginate in Pseudomonas aeruginosa

Background and Objective: The opportunistic pathogen Pseudomonas aeruginosa secrets a capsule-like polysaccharide called alginate which is important for evasion of host defenses, especially in patients with suppressed immunity. Method of alginate determination has an important role in the study of microb...

A Novel SOI MESFET by Implanted N Layer (INL-SOI) for High Performance Applications

This paper introduces a novel silicon-on-insulator (SOI) metal–semiconductor field-effect transistor (MESFET) with an implanted N layer (INL-SOI MESFET) to improve the DC and radio frequency characteristics. The DC and radio frequency characteristics of the proposed structure are analyzed by the 2-D ATLAS simulator and compared with a conventional SOI MESFET (C-SOI MESFET). The simulated result...
