2014 Many biperiodic flows can be modelled by maps of a circle to itself. We decompose the boundary of topological chaos in the space of C1 circle maps of degree 1 into four subsets, and describe the typical routes to topological chaos.

It is known that a number of inference principles can be used to trivialise the axioms of naı̈ve comprehension — the axioms underlying the naı̈ve theory of sets. In this paper we systematise and extend these known results, to provide a number of general classes of axioms responsible for trivialising naı̈ve comprehension.

A long-standing debate questions whether the World Trade Organization’s (“WTO”) formal dispute settlement procedures level the playing field for lower income countries in international trade disputes, or instead, merely give opportunistic and sophisticated countries complex * Trade Counsel, Committee on Ways and Means, U.S. House of Representatives; J.D., Harvard Law School, 2007; M.P.P., Georg...

in purpose of this paper is to discuss the occurance of bifurcation and chaos in nonlinear systems in general, and the pearl-reed model whi.ch has been used for representing the lynamical behavior of the petroleum resources in particular. based on this investigation, it is shown that the observed tluctuations in the petroleum market can be erplained by its interral dynamics and the increase in ...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...
