For the construction of composite surfaces interpolating a given curve net a new local twist estimator was proposed recently (Farin and Hagen, Discount Ghd Eclipse
1992). Some properties of this estimator—including an explicit representation for Gaussian curvature K at the knots of the curve net—are presented in this note.
This article reports on the results of a survey of 164 assistant library directors (ADs) at 137 comprehensive and liberal arts institutions. Findings indicate that while professional credentials, method of appointment, and career expectations were fairly consistent among the ADs, their position responsibilities varied greatly—largely in response to the directors' preferences.
This paper provides a geometrical discussion of affine (including isometric and homothetic), conformal and curvature symmetries in space-time. Emphasis is laid more on a systematic presentation of the material rather than the accumulation of exact solutions of Einstein's equations. A review of recent work is given and some new results presented.
In this paper, several algorithms for the matrix polynomial division are taken into Ghd Online Shop
consideration. Such algorithms represent extensions of known parallel algorithms for the scalar polynomial division with remainder. The interest resides in the comparison of the parallel computational cost of these algorithms in the general non scalar case.
