A new adaptive speech enhancement system, which utilizes a second-generation wavelet transform (SGWT) decomposition and a novel adaptive subband thresholding technique, is presented. The adaptive thresholding technique ...

This article proposes a new output-based method for non-intrusive assessment of speech quality of voice communication systems and evaluates its performance. The method requires access to the processed (degraded) speech ...

The response of screen-printed thick-films of NiO/TiO2 to organic solvent vapours was studied. It was found that these films displayed a significant resistance change in response to the vapours even at room temperature. ...

This paper describes a new low-cost,  low-noise displacement current sensor developed for non-contact measurements of human biopotentials and well suited for detection of human presence applications. The sensor employs a ...

Hemoglobin (Hb) is an important component of red blood cells. The primary function of Hb is to transport oxygen from the lungs to the body tissues and to carry carbon dioxide back to the lungs from the body tissues. The ...

In this paper, a novel optical fiber temperature sensor based on surface plasmon resonance (SPR) is presented. The sensor consists of multimode fiber-photonic crystal fiber-multimode fiber (MMF-PCF-MMF) structure coated ...

In this thesis a novel approach to the management of multiple payload sonar systems is described. The objective of this study is the design, development, and experimental verification of an automated system that facilitates ...

Phase modulation schemes are attracting much interest for use in ultra-fast optical communication systems because they are much less affected by fiber nonlinearities than conventional modulation formats. Semiconductor ...

Particle swarm has proven to be competitive to other evolutionary algorithms in the field of optimization, and in many cases enables a faster convergence to the ideal solution. However, like any optimization algorithm it ...
