We prefer the analytical method in general because it is faster and because the solution is exact. Nevertheless, sometimes we must resort to a numerical method due to limitations of time or hardware capacity.A good example is in finding the coefficients in a linear regression equation that can ...
The method proposed and explained below allows one to determine critical loads, natural frequencies and coefficients of the equation describing the postbuckling equilibrium path for thin orthotropic plates or girders, columns and beams composed of flat orthotropic plates (walls). This method also allows...
The method of variation of parameters is significantly more efficient than both the semi-analytical methods and traditional numerical methods while maintaining comparable accuracy. Unlike the semi-analytical methods, the efficiency of variation of parameters is independent of the nonlinearity. Variation of ...

In this paper we present an alternative method based on analytical and numerical solutions for solving the differential equations which describe heap leaching of one or more solid reactants from porous pellets. We propose to use analytical solutions for the differential equations which describe rate ...
Using the method of Lagrange multipliers with the growth equation (Eq. (6)) as the objective function, we derive necessary conditions at optimal growth, which we term balance equations: $$\forall i\in \{\rm{P},\alpha \}:{\eta }_{i}={\eta }_{\rho }$$ (10) (Theorem 10). Ag...
A batch-demand model was treated by matrix-analytic method in [15]. Namely, a two-commodity model with customers capable of requesting bulk amount for the second commodity (and/or single item for the first one) was studied under the assumptions of a Markovian arrival process (MAP), phase-...
We incorporate this penalty in a fully automated optical design flow using a quasi-Newton optimization method. The performance of our design method is evaluated by designing a series of waveguide demultiplexers (WDM) and mode converters with various footprints and minimum feature sizes. Finally, we...
This method reduces the volume of data to be processed. No filtering is performed on the user level for the study as our flexible framework, and infrastructure can handle the user traffic on the radio side. Raw packets are stored as PCAP/CAP as well for on-demand eMBB QoE evaluation. ...
a quantity based on available historical figures—for instance, forecasting sales for the next quarter based on results of the past year. These applications use advanced statistical algorithms, such as linear andnonlinear regressions, single anddouble exponential smoothing, and the Holt-Winters method....
