yarn tenacity is one of the most important properties in yarn production. this paper addresses modeling of yarn tenacity as well as optimally determining the amounts of the effective inputs to produce yarn with desired tenacity. the artificial neural network is used as a suitable structure for tenacity modeling of cotton yarn with 30 ne. as the first step for modeling, the empirical data is col...

Abstract We present a semianalytical photochemical model of Saturn’s near-equatorial ionosphere and adapt it to two regions (∼2200 ∼1700 km above the 1 bar level) probed during inbound portion Cassini’s orbit 292 (2017 September 9). The uses as input measured concentrations molecular hydrogen, hydrogen ion species, free electrons, well electron temperature. output includes upper limits, or cons...

Tourism demand and its determining factors have been extensively explored over the past decades. Traditionally, study of tourism modeling had focused on use time series models forecasting. Nonetheless, during last years literature has revived approach gravity models, centered structural dimension as opposed to dynamic factors. This survey aims provide a useful overview detailed information that...
