We have developed an original planner, aSyMov, that has been specially designed to address intricate robot planning problems where geometric constraints cannot be simply “abstracted” in a way that has no influence on the symbolic plan. This paper presents the ingredients that allowed us to establish an effective link between the representations used by a symbolic task planner and the representa...

We trace the beginning of symbolic dynamics—the study of the shift dynamical system—as it arose from the use of coding to study recurrence and transitivity of geodesics. It is our assertion that neither Hadamard’s 1898 paper, nor the Morse-Hedlund papers of 1938 and 1940, which are normally cited as the first instances of symbolic dynamics, truly present the abstract point of view associated wi...

In this paper we outline a connection between substitution dynamical systems and systems of partial isometries of IR. Let τ be a primitive substitution and (X,T ) the associated minimal subshift. Associated to each real geometric realization G of τ is a system of partial isometries IG . The subshift (X,T ) generated by τ provides a symbolic coding of the dynamics of IG . This allows us to deduc...

the decorative patterns of islamic pottery have widespread diversity including floral, geometric, inscriptional, animals and human patterns. beside these patterns, there is a group of composed animals including harpies, sphinxes, griffins etc that despite of their few presences, are among the most beautiful and most numinous patterns in islamic pottery. this paper intend to survey different asp...

in this essay, jelinki pottery (clinky- ware ceramics) has been studied as one types of ceramics at arsacides era. raw materials, quality of processing and baking conditions of potteries are some of effective factors in strength and stability of this material. employing purposeful methods of chemical analyses in order to examine such factors and in fact structural science of historical potterie...

These relationships are called constraints. A constraint solver derives then automatically the desig...
