Quantum Theoretical studies of Nanostructures onto Hydrogen Adsorption on V-surface
We have studied the adsorption processes of H2 on the V (100) surface of Vanadium using self consistent field theory.Dissociative adsorptions of H2 are significantly favored compared to molecular adsorptions. There is a significant charge transfer from the first layer of the vanadium surface to the Hydrogen atoms. Three possible adsorption sites, top, bridge and center site, were considered in ...
متن کاملOn Strongly $H_{v}$-groups
The largest class of hyperstructures is the one which satisfies the weak properties; these are called $H_{v}$-structures. In this paper we introduce a special product of elements in $H_{v}$-group $H$ and define a new class of $H_{v}$-groups called strongly $H_{v}$-groups. Then we show that in strongly $H_{v}$-groups $beta=beta^{ast}$. Also we express $theta$-hyperoperation and investigat...
متن کاملOn MISO Wiretap Channel With Delayed CSIT and Alternating Topology
We study the problem of secure transmission over a Gaussian (2, 1, 1)–multi-input single-output (MISO) wiretap channel under the assumption that links connecting the legitimate receiver and the eavesdropper, may have unequal strengths statistically and delayed channel state information is available at the transmitter (CSIT) from both receivers, respectively. We focus on a two state topological ...
متن کاملOn the Performance Limits of Scalar Coding Over MISO Channels
The performance limits of scalar coding for multiple-input single-output channels are revisited in this work. By employing randomized beamforming, Narula et al. demonstrated that the loss of scalar coding is universally bounded by ∼ 2.51 dB (or 0.833 bits/symbol) for any number of antennas and channel gains. In this work, by using randomized beamforming in conjunction with space-time codes, it ...
متن کاملOn Time-Switched Space-Time Transmit Diversity in MISO Systems
We investigate the performance of time-switched space-time transmit diversity schemes applied to a wireless communication system with multiple antennae at the transmitter and single antenna at the receiver. A new method of analysis of timeswitched transmit diversity schemes is presented which builds on an information theoretic equivalent channel and a generalized definition of diversity for cod...
