Some Results on Maxima and Minima of Real Functions of Vector Variables: A New Perspective [PDF]

open access: goldAxioms
This article presents a method for proving several theorems that enable the determination of the maxima and minima of certain classes of real-valued functions with vector variables, without relying on the classical theory based on partial derivatives ...

Asymptotical investigations of the general distributions of the maxima and minima

open access: diamondLietuvos Matematikos Rinkinys, 2000
The convergence rate estimations in the limit theorem of the general distribution functions of the extreme values are presented. There results extend theoretical prepositions of the published work [3].

Massive Fluctuations in the Derivatives of Pair Distribution Function Minima and Maxima During the Glass Transition [PDF]

open access: goldMetals
Parametric changes in the first coordination shell (FCS) of a vitreous metallic Pd42.5Cu30Ni7.5P20 alloy are analysed, aiming to confirm the identification of the glass transition temperature (Tg) via processing of XRD patterns utilising radial and pair ...

The global signal of the 11-year sunspot cycle in the stratosphere: Differences between solar maxima and minima

open access: greenMeteorologische Zeitschrift, 2001
Based on the data of 4 solar cycles, the global structure of the signal of the 11-year sunspot cycle (SSC) in the stratosphere and troposphere was examined in earlier studies, using correlations between the solar cycle and heights and temperatures at ...

Optimization Problems in Spanish Differential Calculus Books Published in the 18th Century

open access: yesMathematics, 2022
History of mathematics and mathematics education research allows us to know, among other issues: the influence that certain textbooks have had on the teaching of school mathematics, in academic or professional training, during a certain historical period;

Estimation of daily mean temperatures: an accurate method for the Douro Valley [PDF]

open access: yesCiência e Técnica Vitivinícola, 2018
Air temperature data from many locations worldwide are only available as series of daily minima and maxima temperatures. Historically, several different approaches have been used to estimate the actual daily mean temperature, as only in the last two or ...

Evolutions of various solar indices around sunspot maximum and sunspot minimum years [PDF]

open access: yesAnnales Geophysicae, 2002
The smoothed monthly sunspot numbers showed that in many solar cycles, (a) during years around sunspot maxima, there was only one prominent maximum, but in some cycles there was a broad plateau. If the beginning and end of these are termed as first
