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 ...
The Successful Delivery of Megaprojects: A Novel Research Method
(SAGE Publications Inc., 2017)
Megaprojects are often associated with poor delivery performance and poor benefits realization. This article provides a method of identifying, in a quantitative and rigorous manner, the characteristics related to project ...
Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), ...
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 ...
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. ...
Shrinkage of recycled aggregate concrete: experimental database and application of fib Model Code 2010
(Springer Netherlands, 2018)
This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC). The study aims at providing an analytic expression for the shrinkage strain of RAC to be ...
Machine Learning Techniques for Modelling Short Term Land-Use Change
(MDPI AG, 2017)
The representation of land use change (LUC) is often achieved by using data-driven methods that include machine learning (ML) techniques. The main objectives of this research study are to implement three ML techniques, ...
Matrix Stiffness Method for Composite and Prestressed Beam Analysis Using Linear Integral Operators
(Springer Verlag, 2015)
In the paper, the analysis of composite and prestressed beams using the matrix stiffness method is presented. The stiffness matrix for the frame element with a moment release at one end and the vector of equivalent nodal ...
Mapping average annual precipitation in Serbia (1961-1990) by using regression kriging
(Springer-Verlag Wien, 2013)
The appearence of geostatistics and geographical information systems has made it possible to analyze complex spatial patterns of meteorological elements over large areas in the applied climatology. The objective of this ...
