The theory of grey system is used when sufficient information of the community under study is not in hand. The grey forecast model is proper when the information variety is fix and certain. Grey model can apply some additional computations to improve forecasting activities when data is insufficient. Through using improved grey model, the assessment error decreases significantly. This study made...

Data overload is a generic and tremendously difficult problem. We examine three different characterizations that have been offered to capture the nature of the data overload problem and how they lead to different proposed solutions. The first characterization is a clutter problem where there is “too much stuff,” which leads to proposals to reduce the number of data bits that are displayed. The ...

Here, a new method called Aboodh transform homotopy perturbation method(ATHPM) is used to solve nonlinear partial dierential equations, we presenta reliable combination of homotopy perturbation method and Aboodh transformto investigate some nonlinear partial dierential equations. The nonlinearterms can be handled by the use of homotopy perturbation method. The resultsshow the eciency of this me...

objective: various studies indicated that the death anxiety is more common in refractory disease (like, cancer); and it effects on many aspects of patients life such as their quality of life and promoting health behavior as well as physical and psychological problems. thus, identifying effective psychological factors on death anxiety in cancer patients could us help to substantial contribute in...

meteorological radars estimate the precipitation using a reflection-precipitation relation as z=arb with a, b coefficients. these coefficients will change from one precipitation to the other one. for the tehran radars they are considered as a=200 and b=1.6. these values are proper when we have moderate precipitations. this assumption causes an error in the estimation of different precipitation ...
