Abstract: A two-dimensional fully implicit finite difference model, which can be easily extended to three dimensions, is developed to study the effect of cut-off walls on saltwater intrusion into the aquifers. This model consists of a coupled system of two nonlinear partial differential equations which describe unsteady density-driven groundwater flow and solute transport. The numerica...
In order to investigate the effect of methanol on the activity of antioxidant enzymes, some compatible osmolytes and biochemical traits of wheat under cut off irrigation conditions, the present experiment as factorial was conducted based on randomized complete blocks design with three replications at the research farm of Faculty of Agriculture and Natural Resources of University of Mohaghegh Ar...
Graph cut minimization formulates the segmentation problem as the liner combination of data and smoothness terms. The smoothness term is included in the energy formulation through a regularization parameter. We propose that the trade-off between the data and the smoothness terms should not be balanced by the same regularization parameter for the whole image. In order to validate the proposed id...
The purpose of this research was to identify and prioritize the barriers to the development of academics’ spin-off companies by using a mixed method in Kermanshah province. In the qualitative stage, using a grounded theory, a sample of 13 people consisting of managers of the academics’ spin-off companies and Kermanshah specialists. Data were gathered through semi-structured interviews. To incre...
AIM/INTRODUCTION Waist circumference (WC) is the most important parameter for diagnosis of metabolic syndrome. The present study was carried out to obtain optimal WC cut-off values for diagnosis of metabolic syndrome in a Japanese population based on the measurement of total intra-abdominal visceral fat volume (VFV), which could be expected to reflect visceral obesity more precisely than viscer...
We review the principles and practical application of receiver-operating characteristic (ROC) analysis for diagnostic tests. ROC analysis can be used for diagnostic tests with outcomes measured on ordinal, interval or ratio scales. The dependence of the diagnostic sensitivity and specificity on the selected cut-off value must be considered for a full test evaluation and for test comparison. All...
