Previous research aimed at developing procedures for preventing the formation of dangerous foot ulcers in diabetic patients has not been very effective, probably because they do not allow contacting patients often enough to persuade them to adapt their behavior before the damage has been done. The current research aims to develop a body area network (BAN) in an on-line monitoring application th...
متن کاملVICO: Visualizing Connected Object Orderings
In modern databases, complex objects like multimedia data, proteins or text objects can be modeled in a variety of representations and can be decomposed into multiple instances of simpler sub-objects. The similarity of such complex objects can be measured by a variety of distance functions. Thus, it quite often occurs that we have multiple views on the same set of data objects and do not have a...
متن کاملThe Descartes Rule of Sweeps and the Descartes Signature
The Descartes Rule of Signs, which establishes a bound on the number of positive roots of a polynomial with real coefficients, is extended to polynomials with complex coefficients. The extension is modified to bound the number of complex roots in a given direction on the complex plane, giving rise to the Descartes Signature of a polynomial. The search for the roots of a polynomial is sometimes ...
متن کاملArithmetic Multivariate Descartes' Rule Arithmetic Multivariate Descartes' Rule
Let L be any number field or p-adic field and consider F := (f1, . . . , fk) where fi∈L[x ±1 1 , . . . , x ±1 n ]\{0} for all i and there are exactlym distinct exponent vectors appearing in f1, . . . , fk. We prove that F has no more than 1+ ( σm(m− 1)2n2 logm )n geometrically isolated roots in Ln, where σ is an explicit and effectively computable constant depending only on L. This gives a sign...
متن کامل7 Descartes ’ Perfect Lens
We give a new, elementary, purely analytical development of Descartes’ theorem that a smooth connected surface is a perfect focusing lens if and only if it is a connected subset of the ovoid obtained by revolving a cartesian oval around its axis of symmetry.
