due to its complexity and destructive nature, convection has been subject of many studies and researches among weather phenomena throughout the world. scientists have attempted for decades to generate different types of models to provide the possibility of abating or, at least, reducing convective weather phenomena effects on people’s lives. in south or southwest of iran, people are familiar wi...

in this short review we look at recent advances in schramm-loewner evolution (sle) theory and its application to critical phenomena. the application of sle goes beyond critical systems to other time dependent, scale invariant phenomena such as turbulence, sand-piles and watersheds. through the use of sle, the evolution of conformally invariant paths on the complex plane can be followed; hence a...

In this paper we present a summary of nonlinear system level problems in beamforming. The paper summarizes first the nonideal phenomena in power amplifiers, mixers, and oscillators. In digital predistortion inversion of the nonlinearity is needed. Not all linear and nonlinear systems are invertible or they may have only a preinverse or postinverse. Commutation is needed in indirect learning arc...

In this paper I argue—against van Fraassen’s constructive empiricism—that the practice of saving phenomena is much broader than usually thought, and includes unobservable phenomena as well as observable ones. My argument turns on the distinction between data and phenomena: I discuss how unobservable phenomena manifest themselves in data models and how theoretical models able to save them are ch...

Timing, intensity, and frequency of biomass removal PREDICTING YIELD LOSS IN affects soybean yield. Yield reduction is less sensitive INDETERMINATE SOYBEAN FROM to biomass removal during vegetative growth because soybean can develop new leaf area that can compensate POD DENSITY USING SIMULATED for temporarily reduced assimilatory capacity. Singer DAMAGE STUDIES (2001) reported that yield reduct...
