The implicit yes{vote commit protocol (IYV), proposed for future gigabit{networked distributed databases, reduces the time required to commit a distributed transaction at the expense of independent recovery of failed participant sites. In this paper, we propose a novel coordination scheme for IYV that reduces the window of vulnerability to blocking and minimizes the time required for the sites ...

A broadband GaN reconfigurable power amplifier based on band-pass filter matching networks is presented in this work. To realize the amplifier, closed-form solution theory and distributed PIN switch are used network design. controls branch circuit of network. This PA designed for 1.2-2.0GHz 2.2-3.0GHz, which has 10W (40dBm) output at least 37.4% drain efficiency (DE) with gain higher than 10dB....

The importance of global climate modeling for long{ term studies of global warming and ozone depletion is the focus of the recent DOE CHAMMP program 7]. We have developed a model and distributed algorithm for 2{D climate modeling which includes ocean intermediate/deep layer dynamics, coupled at-mosphere/biosphere hydrology and velocity interactions , and variable lapse rates. This algorithm all...

In this paper we develop a class of nonlinear generative models for high-dimensional time series. We first propose a model based on the restricted Boltzmann machine (RBM) that uses an undirected model with binary latent variables and real-valued “visible” variables. The latent and visible variables at each time step receive directed connections from the visible variables at the last few time-st...

Quantum key distribution (QKD) and quantum communication enable the secure exchange of information between remote parties. Currently, the distributed-phase-reference (DPR) protocols, which are based on weak coherent pulses, are among the most practical solutions for long-range QKD. During the last 10 years, long-distance fiber-based DPR systems have been successfully demonstrated, although fund...

In this paper, an improved distributed model predictive control (IDMPC) method for the platoon consisting of electric vehicles is put forward. And motion performed in two dimensions, which contains longitudinal and lateral motion. Firstly, a built based on car-following single following vehicle. Then, IDMPC strategy designed with consideration multiple objectives. The symmetrical weight matrice...

In this paper the attention is drawn on analog computer.For scientists attempting to prepare complex designs for simulation approach the analog computer assisted them. Extensive knowledge about the analog methods is required before preparing any analog design. The credit for the advent of analog computer goes to the invention of operational amplifier. Thus in 1950 the engineers and aircraft res...

The detected signal-to-noise power ratio is evaluated for fiber links with periodic amplification. It is shown that the highest ratio is achieved in the limit of a distributed amplifier (g = alpha), but that, alternatively, periodic amplification at intervals of alpha(-1) entails a penalty of less than 2 dB compared with the (ideal) distributed case.
