In the course of making electronic services and facilities more widely accessible and usable, more and more IT systems are incorporating smart cards as a component. We analyzes the side channel attacks for the smart card and similar security evaluation criteria for smart card protection profiles based on the common criterion. Futhermore, we proposes the smart card security evaluation criteria f...

The performance of wireless wideband high data rate indoor communications systems is affected by the channel propagation conditions. In this context, the channel delay profile characteristics constitute a significant contraint by imposing an irreducible error rate which results in a limitation of the transmission rate. In this paper, we examine the effects of equalization techniques on the perf...

In this paper, unequal error protection (UEP) adaptive multiple-input multiple-output (MIMO) system using orthogonal frequency division multiplexing (OFDM) is considered. Our proposed transmission scheme consists of three stages. The inner stage is a UEP adaptive loading, which is introduced to fulfill a certain UEP profile by distributing bits and power across the unitarily transformed eigenbe...

A process of making a symmetrical self-aligned n-type vertical double-gate MOSFET (nVDGM) over a silicon pillar is revealed. This process utilizes the technique of oblique rotating ion implantation (ORI). The self-aligned region forms a sharp vertical channel profile and decreases the channel length Lg. A tremendous improvement in the drive-on current is noted. The electron concentration profil...

In this paper two different channel estimation techniques for a mobile beyond 3G MC-CDMA systems are evaluated. These techniques are the robust MMSE estimation with pre-estimator of autocorrelation channel matrix and the delay profile based estimation. Simulation results, carried out over a realistic propagation channel, compare the proposed channel estimation algorithms, in terms of the mean s...

A novel adaptive equalizer that exploits only the softinformation given by the A Posteriori Probabilities (APPs) of the states of the ISI channel for channel estimation, tracking and equalization is presented. Moreover, the channel tracking capability of the receiver is enhanced by exploiting the knowledge of the powerdelay profile of the link and, therefore, by taking into account an unequal d...

Odors activate lobster olfactory receptor neurons (ORNs) through phosphoinositide signaling that appears to target a Na(+)-gated nonselective cation channel. The Na(+)-gated channel is a potential member of the growing family of transient receptor potential (TRP) channels. Here, we test the effect of potential antagonists on the channel in cell-free patches from cultured lobster ORNs. We show t...

This work addresses a novel problem of maintaining channel profiles on the Web. Such channel maintenance is essential for next generation of Web 2.0 applications that provide sophisticated search and discovery services over Web information channels. Maintaining a fresh channel profile is extremely difficult due to the the dynamic nature of the channel, especially under the constraint of a limit...

Abstract according to the measurement principle and performance requirements of acoustic Doppler velocity profile, a circuit for weak frequency signal processing is designed. The principle, structure, data comparison before after accuracy analysis are introduced. application instrument carried out relevant standards. experimental results show that realizes constant amplitude amplification wide ...

The existence of aquatic weeds in waterways causes several major problems. Some of them are the obstruction of water flow and navigation, island formation, increase of water losses due to evapotranspiration, and difficulty of water arrival to canal ends. This paper aims to discuss the resulting velocity profile changes due to aquatic weeds. Also, it examines the effect of such weeds on the chan...
