Introduction. In the study of uniform approximation to a function of a complex variable by polynomials or by bounded analytic functions, Lipschitz conditions have proved extremely useful in relating degree of approximation to continuity properties of the functions approximated. Parts of this theory are analogous to the older study (S. Bernstein, D. Jackson, de la Vallee Poussin, Montel) of appr...

In this paper, we introduce n-jordan homomorphisms and n-jordan *-homomorphisms and Also investigate the Hyers-Ulam-Rassiasstability of n-jordan *-homomorphisms on C*-algebras.

We present a constructive existence proof that every real skew-Hamiltonian matrix W has a real Hamiltonian square root. The key step in this construction shows how one may bring any such W into a real quasi-Jordan canonical form via symplectic similarity. We show further that every W has infinitely many real Hamiltonian square roots, and give a lower bound on the dimension of the set of all suc...

Soil samples were collected from ten different locations of the Western Jordan Valley (W. J. V.) extending from Pardala (north) to Jericho city (south). The residues of Endosulfan which is the most widely used insecticides in the W. J. V. were detected using Gas Chromatography/ Mass Spectrometry (GC/ MS). The soil samples were collected from two depth levels namely 0-30 and 30-60 cm. The correl...

Participants pressed computer keys to keep a moving dot stimulus within a rectangle, either alone or with a partner they could neither see nor hear. Pressing the A-key or L-key caused the dot to move right or left, respectively, for as long as the key was pressed. Switching between the A and L keys (i.e., turning) proved challenging: concurrently pressing both keys made the stimulus move upward...

For a compact set E with connected complement in the com plex plane we consider a problem of the uniform approximation on E by the weighted polynomials W z Pn z where W z is a continuous non vanishing weight function on E analytic in the interior of E Let A E W be the set of functions uniformly approximable on E by such weighted polynomials If E has empty interior then A E W is completely char ...

A. van den Bosch und W. Daelemans (ITK, Tilburg) untersuchten die Fähigkeit neuronaler Netze (Elmanund Jordan-Netze), Silbengrenzen in orthographischen und phonologischen Repräsentationen niederländischer Wortformen zu bestimmen. Getestet wurden sowohl unterschiedliche Codierungen der Eingaben als auch verschiedene Netzwerk-Architekturen. Zusammenfassend konnte festgestellt werden, daß die verw...

The curvaton reheating in a non-oscillatory inflationary universe model is studied in a JordanBrans-Dicke theory. For different scenarios, the temperature of reheating is computed. The result tells us that the reheating temperature becomes practically independent of the Jordan-Brans-Dicke parameter w. This reheating temperature results to be quite different when compared with that obtained from...
