We propose a decentralized belief propagation-based method, PD-LBP, for multi-agent task allocation in open and dynamic grid and cloud environments where both the sets of agents and tasks constantly change. PD-LBP aims at accelerating the online response to, improving the resilience from the unpredicted changing in the environments, and reducing the message passing for task allocation. To do th...

In the solution methods of the symmetric cone complementarity problem (SCCP), the squared norm of a complementarity function serves naturally as a merit function for the problem itself or the equivalent system of equations reformulation. In this paper, we study the growth behavior of two classes of such merit functions, which are induced by the smooth EP complementarity functions and the smooth...

In order to evaluate the effect of dropping parts of coefficients in H.264 bit-stream, the distortion aroused by coefficient dropping has to be estimated accurately. In this paper, an efficient method is presented to estimate the distortion of a frame during the error propagation caused by single frame coefficient dropping of H.264 bit-stream. At first, through analyzing the image reconstructio...

The wood samples were tested by the technique of stress wave, and the testing results were analyzed by using the statistic software of SPSS. The results showed that the length, density and knots of wood, the sizes of holes and numbers of holes have significant influence on propagation parameters and dynamic modulus of elasticity. Under the same specifications, the propagation time of the stress...

Wireless mobile communication system with selection combining (SC) diversity receiver is investigated in this paper. Received signal envelope experiences α-κ-μ short term fading resulting in system performance degradation. Level crossing rate (LCR) and average fade duration (AFD) of SC receiver output signal envelope are obtained as rapidly converging infinite series expressions. Numerically ev...

We consider two problems encountered in simulation of fluid flow through porous media. In macroscopic models based on Darcy’s law, the permeability field appears as data. The first problem is that the permeability field generally is not entirely known. We consider forward propagation of uncertainty from the permeability field to a quantity of interest. We focus on computing p-quantiles and fail...

The cumulative reaction probability ~CRP! has been calculated for the H21OH↔H2O1H in its full dimensionality by using the centrifugal sudden ~CS! approximation for J.0. The Boltzmann average of the CRP provides the most accurate thermal rate constant to date for the title reaction on the Walch, Dunning, Schatz, Elgersma ~WDSE! potential energy surface ~PES!. It is found that the theoretical rat...

Constant propagation (CP) is a powerful, practically relevant optimization of sequential programs. However, only few approaches have been proposed aiming at making CP available for parallel programs. In fact, because of the computational complexity paraphrased by the catch-phrase \state explosion problem," the successful transfer of sequential techniques is currently essentially restricted to b...

The idea of a variable dark energy has been entertained many times in the literature and from many different points of view. Quintessence is just a popular way to implement this idea in recent times, but so far with little success. Another possibility is to think of the cosmological term, Λ, as a “running quantity” much in the same way as the electromagnetic coupling constant. However, the fact...
