In non-Hamiltonian dissipative systems that have attracting limit cycles there are phase shifts analogous to the geometric phase of Hamiltonian quantum systems. Here the phase variable is the equal-time parametrization of a limit cycle. The phase shift is calculable when the direrentia1 equations of the variables of the systems are known. We study such a system with both numerical and analytica...

the effect of weak shear thickening and shear thinning on the stability of the taylor-couette flow is explored for a carreau-bird fluid in the narrow-gap limit. the galerkin projection method is used to derive a low-order dynamical system from the conservation of mass and momentum equations. in comparison with the newtonian system, the present equations include additional nonlinear coupling in ...

Most classes in an object-oriented program provide access to an object’s state through methods, so that client code does not depend on and cannot interfere with the object’s internal representation composed of fields and internal component objects. In order to extend the benefits of methods to specifications, method contracts may themselves be expressed using methods, hence providing support fo...

In this paper the potential of kinetic energy absorption by means absorbing and storing mechanisms was discussed. The use absorbers is intended to reduce maximum working forces when stopping body.

State reduction of fuzzy automata has been studied by many authors. All of them have dealt with classical fuzzy automata over the Gödel structure and reduction has been done using crisp equivalence relations. In [2, 3, 7] we have made several innovations. We have studied fuzzy automata over a more general structure of truth values, over a complete residuated lattice, we have shown that better r...
