The variational matrix is obtained by linearizing the system of differential equations around the equilibrium. If we denote the equilibria as \(({{\breve{S_{1e}}}, {{\breve{S_{2e}}}, {{\breve{I_{1e}}}, {{\breve{I_{2e}}}, {{\tilde{R}}}_e)\), the variational matrix \...
In this work is used a multiobjective genetic algorithm with restrictions coupled to AspenONE Aspen Plus; so, the complete MESH equations and rigorous phase equilibrium calculations are considered. Results show some tendencies in the design of intensified sequences, according to the nature of the ...

Abstract Conditional equations in its linear form are a standard topic in Geodetic Sciences. We mention for example F.R. Helmert (1907) and H. Wolf (1986).This is a preview of subscription content, log in via an institution to check access. ...
In this section, each multibody-system formulation is explained, and the final form of the motion equations is described. 2.2.1 Embedding technique The formulations for the multibody system can be divided according to the constraint-force consideration method. The embedding technique that eliminates ...
The existence, uniqueness of the system is analyzed, and the stabilities of the equilibrium points are explored. The output of the electronic circuit equations has been inspected graphically and the values of passive components resistor, capacitor and voltage are tabulated. The scrambling protocol is ...
To reveal nonlinear dynamic characteristics of the rotors system,the dynamic differential equations based on nonlinearity of contact and clearance is established.The system equations are numerically integrated,the results of which contain phase diagram,Poincare diagram,spectrogram and bifurcation diagram.It sh...
Polynomial form of equations 2013 − ≤100 [62] Patek and Klomfar [63] give a fast calculation of thermodynamic properties. As an example, the bubble point and dew point temperatures of the NH3/H2O mixture are found from the correlations in Eqs. (7.6) and (7.7), developed by Patek an...
We consider a general Bellman type system of parabolic partial differential equations with a special coupling in the zero order terms. We show the existence of solutions in Lp((0,T);W2,p(O))nW1,p((0,T)×O) by establishing suitable a priori bounds. The system is related to a certain...
