We consider the self-adjoint singularly perturbed two-point boundary value problems. We know that the numerical methods for solution of such problems based on nonpolynomial spline in grid points, can produce the fourth order method only. So that we look for an alternative to obtain higher order methods. We develop the non-polynomial spline in off-step points to rise the order of accuracy. Based...
Points matching between two or more images of a scene shot from different viewpoints is the crucial step to defining epipolar geometry between views, recover the camera’s egomotion or build a 3D model of the framed scene. Unfortunately in most of the common cases robust correspondences between points in different images can be defined only when small variations in viewpoint position, focal leng...
BACKGROUND BMI and waist circumference (WC) are used to screen for cardio-metabolic risk; however it is unclear how well these indices perform in populations subject to childhood stunting. OBJECTIVES To evaluate BMI and WC as indicators of cardio-metabolic risk and to determine optimal cut-off points among 1,325 Guatemalan adults (44 % stunted: 162 cm men). METHODS Cardio-metabolic risk fac...
Background & Objective: Mild cognitive impairment (MCI) is a transient state between normal condition and dementia. Available data indicates that coronary artery diseases (CAD) may increase the risk of MCI. Hence, the early detection of MCI can prevent the progression of cognitive decline. Materials & Methods: A sample of 65 subjects with degrees of CAD was enrolled to the study. For cogniti...
Background and Objectives: Given the importance of the early detection of any outbreak or change in the trend of meningitis, this study was conducted to estimate the fixed and dynamic alarm threshold levels of meningitis and its outbreak in Iran. Materials and Methods: In this study, the data of all patients from 20¬ March 2016 to 20 March 2019 were extracted from the National Meningitis Di...
