 Fuzzy Geostat
The membership function is increasing towards the peak and decreasing away from it.
This determination could be explained in Fuzzy Logic words as the grade of membership (between 0 and 1) of the probability to exceed certain threshold, and then applying this function as the fuzzy boundary of being contaminated or not.
It was intended to show that IK results could be seen as grades of membership under the concept of exceeding certain threshold, and also that such membership once transformed (or modeled) into a function can be used to interact with other membership function using logical operators and fuzzy controls.

 John F. Nash, Jr. - Autobiography
It seems conceivable that if either de Giorgi or Nash had failed in the attack on this problem (of a priori estimates of Holder continuity) then that the lone climber reaching the peak would have been recognized with mathematics' Fields medal (which has traditionally been restricted to persons less than 40 years old).
Also the mathematics faculty were encouraging me to shift into mathematics as my major and explaining to me that it was not almost impossible to make a good career in America as a mathematician.
So I shifted again and became officially a student of mathematics.

 Cauchy [Definition]
Cauchy determinant In mathematics, the Cauchy determinant in linear algebra, named after Augustin Cauchy, is the determinant of the complex n×n matrix CM with entries...
Cauchy distribution The Cauchy-Lorentz distribution is a probability distribution with probability density function where x0 is the location parameter, specifying the location of the peak of the distribution, and γ is the scale parameter which specifies the half-width at half-maximum (HWHM).
Cauchy had two brothers: Alexandre Laurent Cauchy ( 1792 – 1857), who became a president of a division of the court of appeal in 1847, and a judge of the court of cassation in 1849 ; and Eugène François Cauchy ( 1802 – 1877), a publicist who also wrote several mathematical works.

 Joseph Fourier
Fourier treated the initial distribution of temperatures around the ring as a superposition of many simple sinusoids that varied from peak to trough to peak an integer number of times along the circumference of the ring.
Fourier returned to work as assistant to his old mathematics teacher, Bonard, at the École Royale Militaire, later the Collège Nationale, in Auxerre.
Joseph Fourier was born in 1768 in Auxerre in the département of Yonne; a town steeped in history.

 The Bridges of Königsberg
Königsberg was probably at its peak in the late 18th century.
He has never seen the bridges, but will come back with his wife, also a mathematics teacher, when he thinks border crossings will be easier.
It is well-known now that he showed why the tour was not possible, and that his proof developed the branch of mathematics known as Graph Theory, of fundamental importance to networks as we find them in computers today.

 What Makes Beautiful Minds
"Nash would climb another mountain altogether and from a distant peak would shine a searchlight back on the first peak." Or as Nash himself put it, he tended "to think that the thing to do is to get away from what other people are doing and not to follow directly in anyone's recent work."
Nash thought of mathematics as a ferociously competitive sport.
Nash's thesis was just one of a spectacular string of problems that he solved before he turned 30 and the onset of delusions and hallucinations sapped his creative powers.

So I was prepared actually for the possibility that the game theory work would not be regarded as acceptable as a thesis in the mathematics department and then that I could realize the objective of a Ph.D. thesis with the other results.
And it was this idea which in turn, when I was a graduate student at Princeton, led to my interest in the game theory studies there which had been stimulated by the work of von Neumann and Morgenstern.

 Encyclopedia: Correlation function
The system of claim 13 wherein the logic is configured to circularly cross- correlate the first and second combined correlation functions to form a circular cross- correlation function, locate a peak of the circular cross-correlation function, and derive the estimate of the frequency shift parameter from the location of the peak.
In mathematics, and in particular statistics, the Pearson product-moment correlation coefficient (r) is a measure of how well a linear equation describes the relation between two variables X and Y measured on the same object or organism.
Correlation functions used in astronomy, financial analysis, quantum field theory and statistical mechanics differ only in the particular stochastic processes they are applied to.

The illustration will hopefully enhance understanding and peak interest for many students on the topic of a sequence, as well as mathematics related to real life.
The historical significance of studying the Fibonacci sequence is that when the Liber abaci was published, it had a significant impact on European mathematics.
This numeral system fascinated Fibonacci so much that he published a book in 1202 called the Liber abaci in which he introduced the Hindu Arabic numeral system into Europe.

 Advanced diffraction
The incoming X-ray is considered as a plane wave, with peaks in the electric field occurring on planes perpendicular to the wave vector, separated by the wavelength.
In crystallographic applications, we can define the phase of the wave to be zero at the origin of time and space, so that it has a peak at the origin at time zero.
This page is a revised version of the first half of basic diffraction theory, aimed at a deeper understanding of the mathematics and physics.

 Significant Scots - Thomas Drummond
The hour had past, and the sentry was about to leave his post, when the light suddenly burst out like a brilliant star from the top of the hitherto invisible peak, to the delight of the astonished spectators, who were watching with intense anxiety from the other station of survey.
As these new duties required Drummond to reside in London during the winter, he availed himself of the opportunity not only to improve himself in the higher departments of mathematics, but also to study the science of chemistry, which he did with his wonted energy and success.
It was not in mathematics alone, also, that he excelled, but in every other department of science to which he turned his attention; for such was his intellectual tenacity and power of applications, that he never relinquished a subject until he had completely mastered it.

 Root mean square - Wikipedia, the free encyclopedia
In mathematics, root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity.
110 V or 240 V) are almost always quoted in RMS values, and not peak values.
Furthermore, because RMS implies some form of averaging, expressions such as "peak RMS power", sometimes used in advertisements for audio amplifiers, are meaningless.

 Playing both sides, Erica Klarreich
Although investigators could model the flashing ratchet mathematically, the mathematics for doing so is formidable.
Since the troughs of the potential are offset to the right, as the particle drifts, it has a better chance of crossing the peak of the potential to its immediate right than the one to its immediate left.
Brownian motion makes it drift a little to the right or left, so that when the momentary burst of energy subsides, the kinesin molecule may slide down into the nearest neighboring trough—say, to the right.

 Townies (Reviews for Pluperfect/The Brotherhood of Sleeping Car Porters)
Things peak with the uptempo "How Children Learn Mathematics," a crafty song whose effervescent harmonic shifts brings to mind early 90's favorites Indian Bingo.
The Brotherhood of Sleeping Car Porters is a more oblique, lo-fi proposition.
The four-song piece was recorded by Bill Ding's John Hughes III on a farm, and it shows, as the slowed, removed Townies sound makes a quiet, almost rural appearance here.
