Abstract This study investigates the empirical validity of the variability hypothesis in Turkey for the period of February 2005-November 2015, by using cross-sectional relative price data and by focusing on the assumptions of linearity and stability. The linearity assumption between the two variables is ensured by estimating quadratic regression equation. The assumption of stability is secur...

Chemical stability in propellants is important issue. In this article chemical and thermal stability for two kinds of double and single base propellants are investigated. In mass loss test in 90 0C, after 18 days mass loss for both samples is no more than 3%. By stabilizer measurement it was evident that remaining stabilizer content in aged samples are more than 10% in relative to fresh samples...

during the last few decades cereals yield have increased drastically at the national level however, information about yield stability and its resistance to annual environmental variability are scare. in this study long term stability of grin yield of wheat, barley, rice, corn and overall cereals in iran were evaluated during a 40-year period (1971-2011). stability analysis was conducted using t...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

Abstract Understanding why deep nets can classify data in large dimensions remains a challenge. It has been proposed that they do so by becoming stable to diffeomorphisms, yet existing empirical measurements support it is often not the case. We revisit this question defining maximum-entropy distribution on allows study typical diffeomorphisms of given norm. confirm stability toward does strongl...
