Technology evolution is just one class of design-in-nature phenomena, and it is no different than animal evolution, river basin evolution, science evolution, or any other kind of evolution. To see this, consider the physics illustrated in Fig. 3.1. A vehicle consumes fuel and moves on the ...
Thus, the stationary solutions appear only for the symmetric case below the critical limit. In all the other cases, the transient term always appears. In QM, the non-Hermitean operators have been used mainly as mathematical shortcuts, as in the case of the Lippmann-Schwinger equation in the...
In this paper, the initial boundary value problems for a class of nonlinear evolution equations modelling the longitudinal vibration of a elastic bar are studied, the theorems on the existence, both locally and globally in time, uniqueness and smoothness of solutions to the above-mentioned problem ...
This paper deals with the nonlocal problems for a class of nonlinear first-order evolution inclusions. Some existence results are established for the cases of a convex and of a nonconvex valued perturbation terms. Also, the existence of extremal solutions and a strong relaxation theorem are obtain...
One interpretation of our parameters k and ~k controlling the strength of sexual selection is that some individuals belong to a class comprising 1/k of females and 1=~k of males (at maturation), who are qualified to mate and are therefore the only individuals that will have the opportunity...
In the fast-paced realm of gaming, technology is in a constant state of evolution. Before the introduction of variable refresh rate technologies like AMD FreeSync™, gamers often had to deal with screen tearing or increased input lag that traditional solutions like V-Sync imposed. ...
Existence of solutions of strongly nonlinear impulsive equations is proved and some prop... P Sattayatham - 《Nonlinear Analysis Theory Methods & Applications》 被引量: 21发表: 2004年 Boundary control theory for beams and plates We present a general method for exact boundary controllability for a...
The problem of obtaining explicit and exact solutions of soliton equations of the AKNS class is considered. The technique developed relies on the construction of the wave functions which are solutions of the associated AKNS system; that is, a linear eigenvalue problem in the form of a system of...
The foundation of these approaches can be based on the theory of discrete calculus (Grady and Polimeni, 2010; Hirani, 2003), which provides a framework for reformulating continuous energies on graphs such that the corresponding solutions share similar properties (Bougleux et al., 2009; Couprie ...
摘要: In this paper, the blow-up of the solutions to initial boundary value problems of a class of nonlinear pseudo-hyperbolic equationsis studied by using the Fourier transform method , and the conditions under which their solutions blow-up within a finite period of time are given....
