Protein glycation is initiated by a nucleophilic addition reaction between the free amino group from a protein, lipid or nucleic acid and the carbonyl group of a reducing sugar. This reaction forms a reversible Schiff base, which rearranges over a period of days to produce ketoamine or Amadori products. The Amadori products undergo dehydration and rearrangements and develop a cross-link between adjacent...
With the increasing demand of mobility and ad hoc networking, vulnerability of wireless networks is also becoming a crucial issue. This dissertation sheds light on the security features of wireless communication, and proposes a model with an increased integration of security features. The proposed model, a ranked neighbor discovery (RND), and a security adaptive ad-hoc on-demand distance vector (SA-AODV)...
Future wireless systems such as 3G and beyond 3G cellular need flexibility to provide subscribers with a variety of services such as voice, data, images, and video. CDMA (Code Division Multiple Access) has proved very successful for large scale cellular voice systems, as well as has been considered to be a candidate system to support multimedia services in mobile communications. So it could be assumed...
In this paper a new expression of the signal-to-interference-noise ratio (SINR) for single cell multicarrier code division multiple access (MC-CDMA) wireless system in a frequency-selective Rayleigh fading channel is derived and investigated. The expression is much simplified compared to previous research. The SINR performance in uplink channels with frequency-selective Rayleigh fading is shown by...
Orthogonal frequency division multiplexing (OFDM) is an effective multicarrier modulation technique for high speed data communications which suffers from high peak to average power ratio (PAPR). And Wireless broadband (WiBro) is to provide high data rate wireless Internet access with PSS (personal subscribe station) under the stationary or mobile environment, anytime and anywhere for the future 4G...
A process for maximizing the volumetric productivity of recombinant ovine growth hormone (r-oGH) expressed in Escherichia coli during high cell density fermentation process has been devised. Kinetics of r-oGH expression as inclusion bodies and its effect on specific growth rates of E. coli cells were monitored during batch fermentation process. It was observed that during r-oGH expression in E. coli,...
The HF ground wave radar (GWR) system is capable of monitoring a coastal area of 160000 km. The range of the system is 400 km and it has a 120 degrees steering capability. The 40-element phased array receive antenna and the wideband radar waveform allow targets to be located with a range resolution of 400 m and an azimuthal resolution of about 3 degrees . Sample experimental results are presented...
Multirate discrete ladder filter structures are proposed that, when implemented as a digital filter, achieve better passband accuracy than the corresponding uniform-rate filter and, of more importance, may be implemented without the use of digital multipliers and consequently with simpler hardware and reduced filter processing times.
