網頁The mixer coupled with Antenna 2 has a larger harmonic number than that of the other mixer when coupled with Antenna 1. Even more, the mixer coupled with Antenna 2 shows a better mixing performance with the conversion efficiency of −69.6 dB in the 88th harmonic mixing, while the other, coupled with Antenna 1, only has a maximum harmonic number … 網頁2024年4月9日 · This study aimed to determine the effect of irrigation amount (W), nitrogen (N), potassium (K), and zinc (Zn) on the net photosynthetic rate (Pn) of closely planted apple trees on dwarf rootstocks in arid areas of Xinjiang. Taking the “Royal Gala” apple as the experimental material, a mathematical model for Pn was …

網頁2024年7月19日 · This paper reviews and extends a method for the semi-analytical solution of the coupled linear differential equations that describe the linear mode coupling arising in few-mode fibers due to waveguide imperfections. The semi-analytical solutions obtained proved to be accurate when compared to numerical solution methods. These solutions … 網頁2024年1月4日 · The initial boundary value problem of a class of reaction-diffusion systems (coupled parabolic systems) with nonlinear coupled source terms is considered in order to classify the initial data for the global existence, finite time blowup and long time decay of the solution. The whole study is conducted by considering three cases according to initial … 網頁For many years, the parabolic equation (PE) method has been widely used to model the propagation of electromagnetic waves in complex atmospheric, hydrological, and geographical environments. As a forward full-wave analysis method, PE modeling has attracted a lot of interest since it was first proposed by Leontovich and Fock [ 1] in 1946 to ... twitch buffalo
