We address the problem of estimating the source-destination (SD) traffic matrix of a VPN from measurements of aggregated traffic along all access links. We derive two different estimators by formulating the estimation of the SD-traffic matrix in the form of both deterministic and stochastic optimization problems. One estimator yields the estimates from a snapshot of the access link loads; the o...

In this research paper, we use a normalized graph cut measure as a thresholding principle to separate an object from the background based on the standard S membership function. The implementation of the proposed algorithm known as fuzzy normalized graph cut method. This proposed algorithm compared with the fuzzy entropy method [25], Kittler [11], Rosin [21], Sauvola [23] and Wolf [33] method. M...

In the present paper, applicability of the modified fixed grid finite element method in solution of three dimensional elasticity problems of functionally graded materials is investigated. In the non-boundary-fitted meshes, the elements are not conforming to the domain boundaries and the boundary nodes which are used in the traditional finite element method for the application of boundary condit...

In recent years, some researches have been done on simultaneous monitoring of multivariate process mean vector and covariance matrix. However, the effect of measurement error, which exists in many practical applications, on the performance of these control charts is not well studied. In this paper, the effect of measurement error with linearly increasing variance on the performance of ELR contr...

Based on Standard Literature Library of CNKI, opportunities for technical standards development are identified. The initial keywords standard determined based LDA model, whose similar further confirmed by Word2Vec, and then combining model with Word2Vec the representative manufacturing industry determined. According to keywords, core identified using center degree “M-core” method. dimensions fr...
