Modulus of continuity of operator functions [PDF]
Summary: Let \(A\) and \(B\) be bounded selfadjoint operators on a separable Hilbert space, and let \(f\) be a continuous function defined on an interval \( [a,b]\) containing the spectra of \(A\) and \(B\). If \(\omega _f\) denotes the modulus of continuity of \(f\), then \[ \| f(A)-f(B)\| \leq 4\Big[\log\Big(\frac{b-a}{\| A-B\|}+1\Big)+1\Big]^2 \cdot

Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Dunkl analogue of Szász-mirakjan operators of blending type
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

Bernstein Polynomials and Modulus of Continuity
The author describes several properties related to the first order modulus of continuity, which are preserved by the operator given by Bernstein polynomials. Let the function \(\omega(t)\) on \([0,1]\) be a modulus of continuity. By \(H^\omega\) we denote the class of continuous functions on \([0,1]\) satisfying the inequality \(\omega(f,t)\leq\omega(t)

Optimization of the Production of Rubber Compounds Using Mathematical Models
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Weaker forms of continuity [PDF]
This paper is concerned with a study of various weaker forms of continuity. The definitions originated in [1], [2], and [4] . In Chapter I, the definitions of several types of continuity are given and examples are given to show that these are actually ...
