due to the complex structure of the pressure-adjusting device used in most sprinklersfor variable irrigation, it is not possible to observe the flow behavior of the water passingthrough the flow field. in this paper, an integral three dimensional (3d) numerical modelbased on the structural characteristics of the fluidic sprinkler was constructed to simulatethe flow field distribution using comp...

The major objective of this work is to evaluate and study the model coronavirus illness by providing an efficient numerical solution for important model. under investigation composed five differential equations. In study, multidomain spectral relaxation method (MSRM) used numerically solve suggested proposed approach based on hypothesis that domain problem can be split into a finite number subi...

in the present study, a new modelling technique was developed for the modelling and analysis of hyperchaotic systems using an expert system based on wavelet decompositions and the adaptive neuro-fuzzy inference system (anfis). the success and superior properties of this new expert system were shown by applying the hyperchaotic chen system which is a hyperchaotic system. the obtained expert s...

This paper presents a new 2D holographic microwave imaging array (HMIA) technique for medical imaging applications. The HMIA technique has been applied to early stage breast cancer detection and brain stroke detection. Computer models are developed to demonstrate the feasibility of detecting and localizing small brain strokes within a 2D numerical head model and breast tumours within a 3D numer...

1 Overview A simulation contains a sequence of predicted states of a modeled system. A qualitative-numeric simulation is one containing both qualitative and quantitative state information, such that the qualitative information alone would be a qualitative simulation, and the quantitative information alone would be a numerical simulation. Qualitative-numeric simulation is thus a generalization o...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...
