Analysis of linear time-varying (LTV) systems is closely related to time-varying spectral analysis of nonstationary processes. In this paper, we link together the classical theory of linear time-varying systems and wellknown concepts from time-varying spectral analysis. Formulation of the generalized Weyl correspondence provides a unified time-frequency (TF) framework for linear system analysis...

new statistic based models provide a wide area of prediction equipments for different science areas. among these fields biology have just entered the contest of interdisciplinary sciences. drug discovery is a long and expensive process which could be decreased with theoretical approaches. in this study, 500 reported assayed anti cancer molecules were extracted from science direct articles, sket...

background:growth is one of the most important indices in child health. the best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. among these measures, weight growth is the simplest and the most effective way to determine child growth status. weight trend at a given age is the result of cumulative growth e...
