since the analysis of complex services systems by using mathematical modeling techniques, with considering the random patterns prevailing in them, is so difficult or probably impossible, improvement guidelines are often followed based on the experts' experiences using qualitative methods. in the present paper, by employing a discrete event computer simulation methodology, criminal trial sy...

BACKGROUND Research in the predictors of all-cause mortality in HIV-infected people has widely been reported in literature. Making an informed decision requires understanding the methods used. OBJECTIVES We present a review on study designs, statistical methods and their appropriateness in original articles reporting on predictors of all-cause mortality in HIV-infected people between January ...

Additive tree methods are widely used in ecology. To date most ecologists have boosted regression (BRT) methods. However, Bayesian additive (BART) models may offer advantages to previously unexamined. Here we test whether BART has some benefits over the BRT method. do this use two grassland data and 13 hydroclimatic land predictor variables. The dataset contained from a period of drought as wel...

Abstract We theoretically analyze the typical learning performance of ℓ 1 -regularized linear regression ( -LinR) for Ising model selection using replica method from statistical mechanics. For random regular graphs in paramagnetic phase, an accurate estimate sample complexity -LinR is obtained. Remarkably, despite misspecification, consistent with same order as logistic -LogR), i.e. <?CDATA $M=...

introduction proper cleaning and shaping of the root canal system is one of the most important aspects of endodontic therapy. to estimate the canal length before instrumentation in endodontic treatment, traditionally, conventional radiographic techniques and, recently, direct digital radiography (ddr) are applied. the application of computer technology in radiography has allowed less exposure t...

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...
