Novel Composite Powders with Uniform TiB2 Nano-Particle Distribution for 3D Printing

open access: yesApplied Sciences, 2017
It is reported that the ductility and strength of a metal matrix composite could be concurrently improved if the reinforcing particles were of the size of nanometers and distributed uniformly.

Some Abelian, Tauberian and Core Theorems Related to the $(V,\lambda)$-Summability

open access: yesUniversal Journal of Mathematics and Applications, 2021
For a non-decreasing sequence of positive integers tending to infinity $\lambda=(\lambda_m)$ such that $\lambda_{m+1}-\lambda_m\leq 1$, $\lambda_1=1$; $(V,\lambda)$-summability has been defined as the limit of the generalized de la Val\'{e}e-Pousin of a

On the Spaces of $\lambda _{r}$-almost Convergent and $\lambda _{r}$-almost Bounded Sequences [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2020
The aim of the present work is to introduce the concept of $\lambda _{r}$-almost convergence of sequences. We define the spaces $f\left( \lambda _{r}\right) $ and $f_{0}\left( \lambda _{r}\right) $ of $ \lambda _{r}$-almost convergent and $\lambda _{r ...

The binomial sequence spaces of nonabsolute type

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we introduce the binomial sequence spaces b 0 r , s $b^{r,s}_{0}$ and b c r , s $b^{r,s}_{c}$ of nonabsolute type which include the spaces c 0 $c_{0}$ and c, respectively.

Logarithmic matrix transformations into Gw

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We introduced the logarithmic matrix Lt and studied it as mappings into ℓ and G in 1998 and 2000, respectively. In this paper, we study Lt as mappings into Gw.

On the Domain of the Fibonacci Difference Matrix

open access: yesMathematics, 2019
Matrix F^ derived from the Fibonacci sequence was first introduced by Kara (2013) and the spaces lp(F) and l∞(F); (1 ≤ p < ∞) were examined. Then, Başarır et al. (2015) defined the spaces c0(F) and c(F) and Candan (2015) examined the

A note on large gauge transformations in double field theory [PDF]

open access: yes, 2015
We give a detailed proof of the conjecture by Hohm and Zwiebach in double field theory. This result implies that their proposal for large gauge transformations in terms of the Jacobian matrix for coordinate transformations is, as required, equivalent to ...

Matrix transformations and convex spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
In a Hausdorff topological linear space we examine relations between r-convexity and a condition on matrix transformations between null sequences. In particular, for metrizable spaces the condition implies r-convexity.

Equiconvergence of matrix transformations [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
Equiconvergence of matrix transformations is related to the existence of Tauberian constants. Agnew’s result on the equiconvergence of Cesàro and Riesz means is shown to be best possible. Finally, equiconvergence of equivalent arithmetical summation methods related to the prime number theorem is investigated.
