Bayesian changepoint analysis for atomic force microscopy and soft material indentation

, 2008
Material indentation studies, in which a probe is brought into controlled physical contact with an experimental sample, have long been a primary means by which scientists characterize the mechanical properties of materials.

Constraining smoothness parameter and the DD relation of Dyer-Roeder equation with supernovae

, 2013
Our real universe is locally inhomogeneous. Dyer and Roeder introduced the smoothness parameter $\alpha$ to describe the influence of local inhomogeneity on angular diameter distance, and they obtained the angular diameter distance-redshift approximate ...

Estimates for the modulus of smoothness

Journal of Approximation Theory, 1985
In approximation theory it is usual for the order of approximation of a function to be given in terms of the modulus of smoothness of that function, but in practice a quantitative estimate of this modulus will be required. In this paper we introduce certain classes of multivariate functions which are characterized by the singularities of their elements.

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

Advanced Engineering Materials, EarlyView.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.

A note on linear compositions of the Mellin convolution operators in the weighted Mellin-Lebesgue spaces

Demonstratio Mathematica
In this article, we express a numerical form of the convergence using the suitable modulus of smoothness for linear compositions of the Mellin convolution operators.

Modulus of smoothness and theorems concerning approximation on compact groups

International Journal of Mathematics and Mathematical Sciences, 2003
We consider the generalized shift operator defined by (Shuf)(g)=∫Gf(tut−1g)dt on a compact group G, and by using this operator, we define “spherical” modulus of smoothness. So, we prove Stechkin and Jackson-type theorems.

On strong asymptotic uniform smoothness and convexity

, 2017
We introduce the notions of strong asymptotic uniform smoothness and convexity. We show that the injective tensor product of strongly asymptotically uniformly smooth spaces is asymptotically uniformly smooth.
