Synchronisation arises in dynamical systems that are composed of a number of interconnected subsystems. In the paper synchronization in a particular application a supermarket refrigeration system is studied. The temperature control in supermarket display cases is typically maintained by a number of distributed hysteresis controllers. Synchronization is then manifested by the opening and closing...

in this article, we tried to identify mechanisms of technology transfer and their legal basis in buy-back contracts. then, analyze the effect of wto regulations on those contracts. in addition, answer these questions: what are legal mechanisms of technology transfer in buy-back contracts? what are the effects of acceptance of wto rules on technology transfer policies in buy-back contracts and t...

In this article, we use two concepts, measure of non-compactness and Meir-Keeler condensing operators. The measure of non-compactness has been applied for existence of solution nonlinear integral equations, ordinary differential equations and system of differential equations in the case of finite and infinite dimensions by some authors. Also Meir-Keeler condensing operators are shown in some pa...

The results of this paper relate the dynamics of a continuous map/of the interval and the topology of the inverse limit space with bonding map /. These inverse limit spaces have been studied by many authors, and are examples of what Bing has called "snakelike continua". Roughly speaking, we show that when the dynamics of / are complicated, the inverse limit space contains indecomposable subcont...

A bstract We consider Yang-Mills theory with a compact structure group G on four-dimensional de Sitter space dS 4 . Using conformal invariance, we transform the from to finite cylinder $$ \mathcal{I} I × S 3 , where = ( −π/ 2 π/ 2) and is round three-sphere. By considering only bundles P → which are framed ov...

We prove that the van Dam-Veltman-Zakharov discontinuity arising in the massless limit of massive gravity theories is peculiar to Minkowski space and it is not present in Anti De Sitter space, where the massless limit is smooth. More generally, the massless limit is smooth whenever the square of the graviton mass vanishes faster than the cosmological constant.
