Sharp Bounds for Trigonometric and Hyperbolic Functions with Application to Fractional Calculus
(MDPI, 2022)
A new situation to note about the obtained boundaries is the symmetry in the upper and lower boundary, where the upper boundary differs by a constant from the lower boundary. New consequences of the inequalities were ...
Report of RILEM TC 281-CCC: outcomes of a round robin on the resistance to accelerated carbonation of Portland, Portland-fly ash and blast-furnace blended cements
(Springer, 2022)
Many (inter)national standards exist to evaluate the resistance of mortar and concrete to carbonation. When a carbonation coefficient is used for performance comparison of mixtures or service life prediction, the applied ...
Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...
On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Hankel determinants of second and third order for the class S of univalent functions
(Slovak Academy of Sciences, Mathematical Institute, 2021)
In this paper we give the upper bounds of the Hankel determinants of the second and
third order for the class S of univalent functions in the unit disc.
Unordered multiplicity lists of wide double paths
(DMFA Slovenije, 2013)
Recently, Kim and Shader analyzed the multiplicities of the eigenvalues of a Φ-binary tree. We carry this discussion forward extending their results to a larger family of trees, namely, the wide double path, a tree consisting ...
Nonsingular acyclic matrices with full number of P-vertices
(Taylor & Francis Ltd, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
Managing rail service life
(Croatian Metallurgical Society, 2014)
The service life Of tails depends especially on the operational loads and speeds on the railway lines; as well as on the rail maintenance policy. There are multiple aspects of rail maintenance optimization. The following ...
Mechanical and time-dependent properties of high-volume fly ash concrete for structural use
(ICE Publishing, 2016)
A two-phase experimental study on the effect of simultaneous partial replacement of cement and fine aggregate with fly ash on the mechanical and time-dependent properties of high-volume fly ash concrete (HVFAC) is presented. ...
The maximum number of P-vertices of some nonsingular double star matrices
(Discrete Mathematics, 2013)
In this short note, we construct a nonsingular matrix A whose graph is a double star of order
n > 4 with n − 2 P-vertices. This example leads to a positive answer, for n > 6, to a last
open question proposed recently by ...
