Nonsingular acyclic matrices with full number of P-vertices
(Linear & Multilinear Algebra, 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 ...
Establishment of the MGI EDM calibration baseline
(Survey Review, 2013)
This paper deals with the estimation of the quality of the baseline for the calibration of distance measurement devices which was established by Serbian Military Geographic Institute for military use. The basic characteristics ...
The maximum number of P-vertices of some nonsingular double star matrices
(Elsevier B.V., 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 ...
A normalized regression based regional model for generating flows at ungauged basins
(Water Science and Technology, 2013)
Revision of existing methodologies for generating monthly-flow series at ungauged basins based on multivariate nonlinear correlation has led to a simple two-parameter model. While the existing methodology used hydrological, ...
Trajectory-based interpretation of Young's experiment, the Arago-Fresnel laws and the Poisson-Arago spot for photons and massive particles
(Physica Scripta, 2013)
We present a trajectory-based interpretation of Young's experiment, the Arago-Fresnel laws and the Poisson-Arago spot. This approach is based on the equation of the trajectory associated with the quantum probability current ...
Traffic-induced vibrations of frame structures
(Canadian Journal of Civil Engineering, 2013)
Using the spectral element method (SEM), a 2-D numerical model of multi-storey frame structures has been developed. The model has been used to predict traffic-induced vibrations of two, six, and twelve-story concrete ...
Trace element distribution in surface soils from a coal burning power production area: A case study from the largest power plant site in Serbia
(Catena, 2013)
The content of trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the largest coal-fired power plant in Serbia was determined to assess the contribution of emissions to ...
Analisys of sources of information on technology for project managers in civil engineering
(Faculty of Civil Engineering University of Zagreb, 2013)
In everyday work, civil engineers are forced to search for technological information. Out of the many available sources of information, there is no one perfect source. The speed of finding the required information has often ...
An efficient beam-column element for inelastic 3D frame analysis
(Springer Netherland, 2013)
Beam-column elements with section resultant plasticity for the hysteretic behavior of the end plastic hinges are widely used for numerical simulations in earthquake engineering practice because of the good compromise between ...
Computation of Thermal-Stresses and Contraction Joint Distance of RCC Dams
(Journal of Thermal Stresses, 2013)
A new approach in 3D numerical modeling for unsteady phased thermal-stress analysis of a massive concrete hydraulic structure is presented. The temperature field is computed first, providing a drive for the unsteady, ...
