A Procedure for Constructing Peak Functions
نویسنده
چکیده
In this paper, we revisit a procedure for constructing peak functions devised by Bishop. Specifically, let Ω be a bounded domain in R (or C), and let E be a closed subspace of C(Ω) : the class of all complex-valued functions that are continuous on Ω. Let x ∈ Ω; we say that f (here f ∈ E) peaks at x if f(x) = 1 and |f(y)| < 1 ∀y ∈ Ω \ {x}, and we call f a peak function of class E. We present a procedure for constructing a peak function of class E .

In order to investigate the milk and its components curve of Khuzestani buffaloes a total of 9061 data of test-day milk, fat and protein yield of the first lactation period buffaloes collected during 1993-2013 were used. The buffaloes having less than 4 test-day records were removed. The lactation days was considered from the 5th to 210th days of lactation. Five different functions of Wood, Wil...

متن کاملMixed two-stage derivative estimator for sensitivity analysis
In mathematical modeling, determining most influential parameters on outputs is of major importance. Thus, sensitivity analysis of parameters plays an important role in model validation. We give detailed procedure of constructing a new derivative estimator for general performance measure in Gaussian systems. We will take advantage of using score function and measure-value derivative estimators ...
متن کاملConstructing Two-Dimensional Multi-Wavelet for Solving Two-Dimensional Fredholm Integral Equations
In this paper, a two-dimensional multi-wavelet is constructed in terms of Chebyshev polynomials. The constructed multi-wavelet is an orthonormal basis for space. By discretizing two-dimensional Fredholm integral equation reduce to a algebraic system. The obtained system is solved by the Galerkin method in the subspace of by using two-dimensional multi-wavelet bases. Because the bases of subs...
