In this paper we present a new web based Distributed File System server management tool to perform load balancing across multiple servers. The Distributed File System from Distributed Computing Environment (DCE DFS) is a collection of many file systems mounted onto a single virtual file system space with a single namespace. The tool is based on rule-based data mining techniques and graph analys...

statement of the problem: vertical root fractures are catastrophic events that often result in tooth extraction. many contributing factor are associated with increasing incidence of vertical root fracture. root canal preparation is one of the predisposing factors which can increase the root susceptibility to vertical fracture. purpose: the aim of this study was to compare the effects of three d...

Objective: The current study aimed at assessing the induced apical pressure various simulated irrigantflow rates. Materials and Methods: Forty eight freshly extracted single-rooted premolars were decoronatedand prepared to size 30 0.04 taper using HY-Flex CM rotary file system scanned cone-beamcomputed tomography (CBCT). images reconstructed three-dimensional Computer-aideddesign models (CAD) 3...

A stochastic model of single-file transport was developed as the Markov process in continuous time technique. The model was constructed using an EC-1060 computer. Unidirectional fluxes were investigated and populations of channels were correlated with flux fluctuations. The profiles of channel populations were shown to have nonlinear shapes even with the transport of nonelectrolyte (the classic...

We introduce a stochastic equation for the microscopic motion of a tagged particle in the single-file model. This equation provides a compact representation of several of the system's properties such as fluctuation-dissipation and linear-response relations, achieved by means of a diffusion noise approach. Most importantly, the proposed Langevin equation reproduces quantitatively the three tempo...

objectives: during root canal preparation, apical extrusion of debris can cause inflammation, flare-ups, and delayed healing. therefore, instrumentation techniques that cause the least extrusion of debris are desirable. this study aimed to compare apical extrusion of debris by five single-file, full-sequence rotary and reciprocating systems. materials and methods: one hundred twenty human mandi...

We have used dynamic Monte Carlo(DMC) methods and analytical techniques to analyze single-file systems for which diffusion is infinitely fast. We have simplified the master equation removing the fast reactions, and we have introduced a DMC algorithm for infinitely fast diffusion. The DMC method for fast diffusion give similar results as the standard DMC with high diffusion rates. We have invest...

The stationary states of driven diffusive single-file systems, connected to boundary reservoirs with fixed particle density are shown to be selected by an extremal principle for the macroscopic current. Given the current one obtains the exact firstand secondorder non-equilibrium phase transition lines for the bulk density as a function of the boundary densities. The basic dynamical mechanism be...

We investigate through non-equilibrium molecular dynamic simulations the flow of anomalous fluids inside rigid nanotubes. Our results reveal an anomalous increase of the overall mass flux for nanotubes with sufficiently smaller radii. This is explained in terms of a transition from a single-file type of flow to the movement of an ordered-like fluid as the nanotube radius increases. The occurren...
