We propose an original method for determining suitable refracting profiles between two media to solve two related problems: to produce a given wave front from a single point source after refraction at the refracting profile, and to focus a given wave front in a fixed point. These profiles are obtained as envelopes of specific families of Cartesian ovals. We study the singularities of these prof...
متن کاملRefracting profiles and generalized holodiagrams
The recently developed concept of refracting profiles and that of refraction holodiagrams are combined so that the classical Abramson holodiagrams can be generalized taking into account a wider class of wave fronts and refraction at an interface, whenever regions of caustics are avoided. These holodiagrams are obtained as envelopes of specific families of Cartesian Ovals with an appropriate par...
متن کاملA Qualitative Method to Construct Phase Portraits
We have developed and implemented in the QPORTRAIT program a qualitative simulation based method to construct phase portraits for a significant class of systems of two coupled first order autonomous differential equations, even in the presence of incomplete, qualitative knowledge. Differential equation models are important for reasoning about physical systems. The field of nonlinear dynamics ha...
متن کاملIntegrating Public Domain Data to Construct Community Profiles
Introduction In recent times there has been an increase in the availability of and requirement for public domain data that can be used to construct community level profiles in order to study contextual level phenomena. In this paper, we will review the developments that have given rise to this requirement, and explain how we have constructed a database of community characteristics at a postcode...
متن کاملPurely Algebraic Method to Construct Toric Schemes
In this article, we first give some elementary proprieties of monoids and fans, then construct a toric scheme over an arbitrary ring, from a given fan. Using Valuative Criterion, we prove that this scheme is separated and give the sufficient and necessary condition when it is proper. We also study the regularity and logarithmic regularity of it. Finally we study the morphisms of toric schemes i...
