DEMATEL method is a methodology to deal with complex systems. Its core process visualize structurally the graphical interrelation among some critical factors known as most important affecting on performance or decision making issues. The initial direct influence matrix in would be assessed by integer scale of 0,1,2,3,4 for "no influence" , "low influence", "medium "high and "very high respectiv...

as is well known, estimating parameters of the tree-parameter weibull distribution is a complicated task and sometimes contentious area with several methods vying for recognition. weibull distribution involves in reliability studies frequently and has many applications in engineering. however estimating the parameters of weibull distribution is crucial in classical ways. this distribution has t...

We present the adaptation of our model for the validation of key distribution and authentication protocols to address specific needs of protocols for electronic commerce. The two models defer in both the threat scenario and in the formalization. We demonstrate the suitability of our adaptation by analyzing a specific version of the Internet Billing Server protocol introduced by Carnegie Mellon ...

The quasi-classical ∂̄-dressing method is used to derive compact generating equations for dispersionless hierarchies. Dispersionless Kadomtsev-Petviashvili (KP) and two-dimensional Toda lattice (2DTL) hierarchies are considered as illustrative examples.

We propose a method to study the time evolution of Bose-Einstein condensed gases perturbed from an initial thermal equilibrium, based on the Wigner representation of the N-body density operator. We show how to generate a collection of random classical fields sampling the initial Wigner distribution in the number conserving Bogoliubov approximation. The fields are then evolved with the time depe...

Sample preparation for transmission immunoelectron microscopy techniques is pivotal to preserve cell architecture and to maintain antigen epitopes. We propose a “non-classical” method in order to obtain the above-mentioned conditions. In a pilot series of experiments, we found a mixture of 2.0% paraformaldehyde/0.1% glutaraldehyde in 0.1 M PBS (pH 7.4) to be an optimal fixing solution. In this ...
