the part of precipitation that directly meets the water requirements of a plant, is termed the effective rainfall. effective rainfall estimation methods consist of: direct measurement, empirical methods, and soil-water balance modeling. due to the high costs of measurements and storing devices such as lysimeter, empirical and balance methods are most commonly used to estimate the effective rain...

The receiver operating characteristic (ROC) curve is one of the most commonly used methods to compare the diagnostic performances of two or more laboratory or diagnostic tests. In this thesis, we propose semi-empirical likelihood based confidence intervals for ROC curves of two populations, where one population is parametric while the other one is non-parametric and both populations have missin...

The semi-empirical tight-binding methods GFN1-xTB and GFN2-xTB are applied to calculations of structure, energy normal vibrations the molecule 2-(2'-hydroxyphenyl)benzoxazole undergoing excited state intramolecular proton transfer. results compared with ones obtained by density-functional hydrogen interaction corrections density functional theory. method is found provide good correspondence mor...

The freezing of food is one of the most significant applications of refrigeration. Numerous semi-analytical/ empirical methods for predicting food freezing times have been proposed. Therefore, a quantitative evaluation of selected semi-analytical/empirical food freezing time prediction methods is provided in two parts. This report focuses on methods that apply to regularly shaped food items, wh...

several empirical methods for flood flow rate estimation have been presented. in this study,eight new empirical runoff estimation method including dredge & burge, bourges, inglis, faning, hyderabad, burkli ziegler, cramar and possenti were calculated in bakhtegan watershed which is located in fars province. after studying empirical methods for annual flood flow rate estimation and comparing...
