In this study, an artificial neural network (ANN) model was developed to predict the gloss of thermally densified wood veneers. A custom application created with MATLAB codes employed for development multilayer feed-forward ANN model. The species, temperature, pressure, measurement direction, and angle incidence were considered as inputs, while output Model performance evaluated by using mean a...

Abstract In this study, the CCHE2D model was used to analyze flow patterns in Tigris River Baghdad city around a water treatment plant. To end, calibrated and validated steady-state using relevant boundary conditions. The initial surface level at Sarai station for three discharges of 289, 530, 870 m 3 /s. Hence, appropriate manning roughness modulus equivalent mixing length turbulent models wer...

This paper presents steam temperature models for steam distillation pilot-scale (SDPS) by comparing Pseudo Random Binary Sequence (PRBS) versus Multi-Sine (M-Sine) perturbation signal Both perturbation signals were applied to nonlinear steam distillation system to study the capability of these input signals in exciting nonlinearity of system dynamics. In this work, both linear and nonlinear ARX...

Terminal velocity of chickpea, rice and lentil seeds has been experimentally measured by suspending the seeds in an air stream. In order to assessment the effects of seed size and moisture content on terminal velocity a completely randomized design in factorial experiment was carried out. The results showed that size and moisture content have significant effects (p<0.01) on terminal velocityin ...

The main objective of this study was to compare the goodness of fit of five non-linear growth models, i.e. Brody, Gompertz, Logistic, Richards and von Bertalanffy in different animals. It also aimed to evaluate the influence of the shape parameter on the growth curve. To accomplish this task, published growth data of 14 different groups of animals were used and four goodness of fit statistics w...

ABSTRACT The body weight (BW) of an animal is a vital economic trait that might help in decision-making the handling animals. objective present study was to develop equations for prediction BW Pelibuey sheep using scrotal circumference (SC). (23.40 ± 6.96 kg) and SC (20.25 6.19 cm) have been recorded 405 male at Southeastern Center Ovine Integration, Mexico. Linear, logarithmic, quadratic, expo...

Climate change is found to be the most important global issue in the 21st century, so to monitor its trend is of great importance. Atmospheric General Circulation Models because of their large scale computational grid are not able to predict climatic parameters on a point scale, so small scale methods should be adapted. Among downscaling methods, statistical methods are used as they are easy to...

The main objective in production blasting is to achieve a proper fragmentation. In this paper, rock fragmentation the Sarcheshmeh copper mine has been predicted by developing a model using artificial neural network. To construct the model, parameters such as burden to spacing ratio, holediameter, stemming, total charge-per-delay and point load index have been considered as input parameters. A m...
