The amplification of acoustic phonons in a superlattice in the presence of an electric field cos( ) has been investigated theoretically and numerically by computational methods. The calculation is done in the hypersound ...

We report on theoretical analysis of high frequency conductivity in carbon nanotubes. Using the kinetic equation with constant relaxation time, an analytical expression for the complex conductivity is obtained. The real ...

Acoustoelectric effect (AE) in a non-degenerate Fluorine modified single walled carbon nanotube (FSWCNT) semiconductor is studied theoretically using the Boltzmann’s transport equation. The study is done in the hyper sound ...

Acoustoelectric Effect AE in degenerate Carbon Nanotube (CNT) was theoretically studied for hypersound in the regime ql >> 1. The dependence of acoustoelectric current jac on the acoustic wave number ~ and frequency ωq at ...

With the increase in structural complexities in modern cities, many operations, be they military, police, fire service, intelligence, rescue, or other field operations, require localization services and online situation ...

Identity management is crucial in cyberspace where infringement of one’s privacy, copy right disputes, theft and other malicious activities are very rampant. There exists a need of ownership identification and authentication ...

A proof of ownership based on digital forensics evidence is the way forward in solving ownership disputes in the ever growing cyberspace that confronts us today. A strong proof beyond all reasonable doubts with the good ...

This paper reports a comparison between a sedimentation method of determining particle size distribution and a microscopic method and also some data on hydrated lime. Glass spherules were prepared from pyrex glass and ...

Multi-spectral imaging (MSI) has made diagnosis of microscopic samples considerably easier and information abound. Most MSI systems use continuum light sources and filters for imaging purposes. However, these light sources ...

Security of digital images in today’s cyber is a major concern. Transmission of compressed and uncompressed multimedia data is necessary for communication between different devices. Devices of different screen features and ...
