in this study, the ability of generalized additive model (gam) for mapping potential distribution of ferula ovina boiss, and the description of species response curves to environmental variables were examined in fereidonshar region with area of 1000 square kilometers located in west of isfahan province. the presence and absence data of the species were collected from 278 sites (including 138 pr...

In the context of wireless sensor networks, the pairwise key distribution scheme of Chan et al. has several advantages over other key distribution schemes including the original scheme of Eschenauer and Gligor. However, this offline pairwise key distribution mechanism requires that the network size be set in advance, and involves all sensor nodes simultaneously. Here, we address this issue by d...

The purpose of the study is a comparative analysis methods for graphic analytical determination characteristics moist air in multistage compressors. Two are compared, which differ used I-d-diagrams: unified terms pressure and atmospheric. I-d-diagrams from atmospheric ones by diagrams saturated relative humidity () only at various pressures. For compressors, curves plotted on compressed interco...

The elastic pressure/volume (P/V) curve obtained by the multiple linear regression (MLR) technique using a new model, was compared with the quasi-static P/V points obtained by the rapid airway occlusion technique. Seven infants were studied during mechanical ventilation using a pressure controlled mode. The resistive pressure was subtracted from airway opening pressure, thus determining the ela...

The receiver operating characteristic (ROC) curve is widely used for diagnosing as well as for judging the discrimination ability of different statistical models. Although theories about ROC curves have been established and computation methods and computer software are available for cross-sectional design, limited research for estimating ROC curves and their summary statistics has been done for...

A knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. Hydrologists have always been concerned about Depth- Area- Duration (DAD) for a specific storm in a watershed. An intense storm occurred on June 6, 1992 which claimed some lives in parts of Mashhad, Khorasan Province, Iran. Data of rainfall depth at 29 raingauge stations around the city and ...

The major goal of this study was to compute the flow appearances chosen midblock and evaluate road sections using various performance metrics that analyzed these in both current future conditions. Performance measure parameters at operational period road. Therefore, work examined 2-way 2-lane roads with measures. capacity mid blocks also determined by plotting curves level service arrived Sidra...
