The position, surface area and visual field representation of human visual areas V1, V2 and V3 were measured using fMRI in 7 subjects (14 hemispheres). Cortical visual field maps of the central 12… (More)

We are concerned with the problem of finding among all polynomials of degree at most n and normalized to be 1 at c the one with minimal uniform norm on 1. Here, I is a given ellipse with both foci on… (More)

The conjugate gradient algorithm for solving Hermitian positive definite linear systems is usually combined with preconditioning in order to speed up convergence. In recent years, there has been a… (More)

Abstract. Let φm be a polynomial satisfying some mild conditions. Given a set R ⊂ C, a continuous function f on R and its best approximation p n−1 from Πn−1 with respect to the maximum norm, we show… (More)

Frequency differences between major national timing centers are being resolved with uncertainty of less than 1 part in 1014, using satellites of the Global Positioning System (GPS) in common-view.… (More)

The focus of our interest is the temporal development of the temperature distribution within a premature infant inside an incubator. With respect to the real world situation, there is the need to… (More)

Let T be a Jordan curve in the complex plane, and let Í) be the compact set bounded by T. Let / denote a function analytic on O. We consider the approximation of / on fî by a polynomial p of degree… (More)

interpretation is used as an e cient mechanism to evaluate range constraints such as x > 0 or x 6= 0 which occur in the conditions of many rewrite rules. AutoBayes implements as a rewrite system a… (More)

The design principles of the Physikalisch-Technische Bundesanstalt's (PTB's) new primary clock, CS2, are reported. Experimental results concerning C field homogeneity, RF power dependence, cavity… (More)
