Spatial cross-validation and average-error statistics are examined with respect to their abilities to evaluate alternate spatial interpolation methods. A simple crossvalidation methodology is described, and the relative abilities of three, dimensioned error statistics—the root-mean-square error (RMSE), the mean absolute error (MAE), and the mean bias error (MBE)—to describe average interpolator...

Mathematical reasoning is a critical feature emphasized in the objective of mathematics education since it may be utilized to solve mathematical problems and other difficulties. This study aims provide student worksheets based on Realistic Mathematics Education (RME) circle material that are valid, practical, useful increasing students' abilities. research used 4-D development model. Validation...

This paper aims to propose a method to do authenticity verification of handwritten signatures based on the use of digital image processing and artificial neural networks techniques through the backpropagation learning algorithm with 500 and 901 approaches, in order to optimize this verification process and act as a decision support tool, in an automated way. The results showed an average percen...

In this study, simple and multiple regression models were developed to estimate the monthly average daily global solar radiation in Lawra, Ghana using ground measurement of horizontal irradiance (Nov 2020–May 2022) typical meteorological year (TMY) data (Jan 2017–Dec 2019). Various predictor variables such as sunshine ratio, minimum relative humidity maximum temperature etc. correlated from TMY...
