In random network models, sizes for pores and throats are distributed according to a truncated Weibull distribution. As result, parameters defining the shape of distribution critical characteristic network. this paper, an algorithm distribute in was established more representatively describe topology porous media. First, relations between dimensionless throat were studied series standard curves...

A phenomenological two-fluid model of the (time-reversible) spectrally-truncated 3D Euler equation is proposed. The thermalized small scales are first shown to be quasi-normal. The effective viscosity and thermal diffusion are then determined, using EDQNM closure and Monte-Carlo numerical computations. Finally, the model is validated by comparing its dynamics with that of the original truncated...

We consider the spectral truncation as regularization for an ill-posed non-homogeneous parabolic final value problem, and obtain error estimates under a general source condition when data, which consist of term well value, are noisy. The resulting estimate is compared with corresponding Lavrentieve method, showed that method has no index saturation.

The authors will demonstrate how a major Chemical Process company has successfully utilized this new technique to answer questions such as: 1. Do I have a reliability problem or a production problem? 2. What is the demonstrated capacity of my plant? 3. What are efficiency/utilization losses costing me? 4. What is the reliability of my process plant? The Weibull technique described has helped th...

BACKGROUND Analyzing time-to-onset of adverse drug reactions from treatment exposure contributes to meeting pharmacovigilance objectives, i.e. identification and prevention. Post-marketing data are available from reporting systems. Times-to-onset from such databases are right-truncated because some patients who were exposed to the drug and who will eventually develop the adverse drug reaction m...
