Steganography is the art and science of writing hidden messages in such a way that no one apart from the sender and the receiver would realize that a secret communicating is taking place. Unlike cryptography which only scrambles secret data keeping them overt, steganography covers secret data into medium files such as image files and transmits them in total secrecy avoiding drawing eavesdropper...

The development of smart sensors capable to analyse data gathered on the process line and give a real time feedback has been undergoing extensive research in last years due its potential benefits optimisation products improvement. In this paper, novel approach detect monitor pH conductivity using 2D electrical resistance tomography (ERT) is proposed for first reacting system. As study case, rea...

Dyadic Green functions for time–harmonic fields in a homogeneous, isotropic, dielectric– magnetic medium, moving with constant velocity, are derived by first implementing a simple transformation and then using the dyadic Green functions available for uniaxial dielectric–magnetic mediums.

The preparation and observations of spheroplast W303 cells are described with Environmental Scanning Electron Microscope (ESEM). The spheroplasting conversion was successfully confirmed qualitatively, by the evaluation of the morphological change between the normal W303 cells and the spheroplast W303 cells, and quantitatively, by determining the spheroplast conversion percentage based on the OD...

The more efficient network transmission rate and increasingly popular hardware technology brought by 5G have driven the rapid development of online HD short videos. As one most video mediums in China, Douyin, its international version known as TikTok, has a large youth user base, influence on growth attracted widespread attention from families, society, academia. Therefore, it is important to s...

Previous work on the vitamin B12 content of the aqueous humour (Phillips, Ainley, van Peborgh, Watson-Williams, and Bottomley, I968) suggests that the levels found in a series of mainly elderly patients (mean: 299 pg./ml.) are of the same order as those found in cerebrospinal fluid (mean: 21 pg./ml.) (Kidd, Gould, and Thomas, I963). As an extension of this study, the response of aqueous vitamin...
