 integration method
 Compared with the traditional direct step-by-step integration method, the proposed method, with a sufficient number of modes included, can significantly reduce the computational time with almost the same precision. Relaxation oscillations of the concentrations of the system participants were demonstrated using the numerical integration method. An integration method is proposed that yields stable numerical results-continuous profiles of the distribution of the basic gas parameters in the shock are obtained. Below a solution of the problem of stationary waves is obtained by the method of expansion in the small parameter in two regions with subsequent matching and also by a numerical integration method. The proof of the main result is based on the contour integration method with some modifications from analytic perturbation theory and from the approach proposed earlier by M. 更多
 integration
 Of special interest are the Mellin operators of differentiation and integration, more correctly of anti-differentiation, enabling one to establish the fundamental theorem of the differential and integral calculus in the Mellin frame. Wavelets, generalized white noise and fractional integration: The synthesis of fractional Brownian motion The desired $\mathfrak{M}_{q}\left(\mathbb{T}\right)$-functional calculus for $T$ then results from an extension criterion for spectral integration obtained in the general Banach space setting. Tools used to obtain such results are the Van der Corput lemma, integration by parts, Young's inequality and the interpolation theory. N-aminoimidazoles and pyridine oxide derivatives) which seem to interfere with a post-integration, transcription transactivation event. 更多
 integral method
 The integral method of Cohen and Reshotko is used to calculate the flow in the boundary layer. An integral method of computing both the first moments of the hydrodynamic fields and the turbulence intensity and the root-mean-square values of the enthalpy pulsations is proposed in Section 1. Reference [8] used a approximate Karman-Polhausen integral method for a very simple system of equations. Problems concerning the initial and main sections of a submerged jet were solved in [6] by the integral method on the basis of this model and the assumed equality of the mean velocities of the gas and particles. The flow in the monoparametric near wake is calculated by the integral method [1] while the flow in the nonviscous jet is calculated by the method of through calculation using a monotonic explicit difference system of the first order of accuracy [2]. 更多
 integration methods
 The pseudorandom and quasi-random integration methods are compared using the rendering equations that have analytical solutions. Acoustical multipath flow measurements based on quadrature integration methods The technique provides precision estimates of flow rates owing to the use of quadrature integration methods. Numerical integration methods for the Takagi-Taupin equations for crystals of rectangular cross section Some energy eigenvalues are numerically calculated and compared with those obtained by other methods such as asymptotic iteration, supersymmetry, numerical integration methods, and the schroedinger Mathematica package. 更多
