DERIVATIONS ON MORITA RINGS AND GENERALIZED DERIVATIONS
Journal of Algebra and Its Applications, 2011In this note, derivations on Morita rings (generalized matrix rings) are introduced and generalized derivations on rings are proved to be Morita invariant without involvement of any homology theory.

The Derivative and Higher Derivatives
2007The derivative of a function, even if it exist everywhere, can be discontinuous. For example, if \(f\left( x \right) = {x^2}\sin \frac{1}{x}\), for x ≠ 0, f(0) = 0, then for x ≠ 0, \(f'\left( x \right) = - \cos \frac{1}{x} + 2x\sin \frac{1}{x}\), which does not tend to any limit as x tends to 0, although f′(0) exists and equals 0, as may be easily ...

Man betrachtet die Ableitbarkeit im klassischen Prädikatenkalkül durch irgendein \(\langle R,X\rangle\), wobei \(X\) eine Menge von Formeln ist, die als Axiome betrachtet werden, und \(R\) eine Menge von Ableitungsregeln ist. Bei fixierten \(\langle R,X\rangle\) soll für eine beliebige Regelmenge \(r\) der Ausdruck \(r\in\text{Der}(R,X)\) bedeuten ...

Derivation of the third-order directional derivative
Pattern Recognition Letters, 1993Summary: We give an easy derivation of the third order directional derivative in the direction of the gradient of the intensity function. The obtained formula is a correction of the formula found by \textit{J. J. Clark} [IEEE Trans. Pattern Anal. Mach. Intell. 11, No. 1, 43-57 (1989; Zbl 0665.68066)].

[Electrocardiograms: derived derivations!]
Revue de l'infirmiere, 2018Simple and non-invasive, the electrocardiogram is a basic examination for studying how the cardiac muscle functions. Very commonly used, it nonetheless requires great rigour when applying the electrodes to avoid false results that can be harmful to appropriate care for the patient. A reminder of good practices.
