Abstract The spontaneous emission spectrum from a driven three-level atom placed inside a double-band photonic crystal has been investigated. We use the model which assumes the upper levels of the atomic transition are coupled via a classical driving field. The transition from one of the upper levels to lower level couples to the modes of the modified reservoir, and the transition from the oth...

throughout the current study, the appropriate function for a description of egg production curve in a commercial broiler dam line was determined through fittings of a number of six mathematical models, namely: incomplete gamma function (wm): modified incomplete gamma function (mwm): compartmental function (cm): modified compartmental function )mcm): polynomial regression function of ali and sch...

In 2010, Jain et al. [JJUW10] provided the first proof that QIP=PSPACE. Jain et al. used a constructive argument which applied the matrix multiplicative weight update method to a semidefinite programming problem formulation of a QMAM protocol to achieve this proof. The proof that QIP= PSPACE was alternately characterized by Xiaodi Wu [Wu10] that same year; Xiaodi Wu’s method, however, was simpl...

This study is to investigate the short- and long-run causal relationship between agglomeration (localization and urbanization) economies and labor productivity in the manufacturing sector of 28 Iranian provinces over an 11-year period, 2001–2011. Fully Modified Ordinary Least Squares (FMOLS) method was used to estimate our long-run panel data model. The empirical findings suggested that localiz...

Coupled modified nonlinear Schrödinger(CMNLS) equations describe the pulse propagation in the picosecond or femtosecond regime of the birefringent optical fibers. In this paper, we use the Fokas method to analyze the initialboundary value problem for the CMNLS equations on the half-line. Assume that the solution u(x, t) and v(x, t) of CMNLS equations are exists, and we show that it can be expre...

Non linear predictive control may require signiicant oo-line and on-line computations. This paper gives a nonlinear predictive control algorithm based on successive oo-equilibrium linearisation which requires less computation whilst accounting for nonlinear system behaviour. A nonlinear example (the pendulum and cart system) is used to show that the method provides a practical tradeoo between c...
