Ski jump design
(Proceedings of the Institution of Civil Engineers-Water Management, 2010)
This paper is concerned with ski jump design for overflow dams and chute spillways. Despite the vast scope of literature on this subject, research in this field is still needed. Three important issues are addressed: take-off ...
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, ...
Bimoment Contribution to Buckling of Thin-Walled Beams with Different Boundary Conditions
(American Society of Civil Engineers (ASCE), 2017)
In this paper the influence of bimoment, induced by external axial loads, on the global buckling of thin-walled Z-section beams, subjected to different boundary conditions, is studied. Since bimoment varies along the beam ...
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 ...
Speeding up the water distribution network design optimization using the Delta Q method
(IWA Publishing, 2016)
To optimize the design of a water distribution network (WDN), a large number of possible solutions need to be examined; hence computation efficiency is an important issue. To accelerate the computation, one can use more ...
Experimental Study on Scour at a Sharp-Nose Bridge Pier with Debris Blockage
(American Society of Civil Engineers (ASCE), 2018)
Previous experimental research on the effects of debris on pier scour has focused primarily on circular and rectangular piers with debris present just under flow free surface. Debris-induced scour around sharp-nose piers, ...
Stormwater biofilters: A new validation modelling tool
(Elsevier, 2016)
Stormwater biofilters must be validated before they can be a trusted component of the treatment train used for water supply augmentation. Currently, only in situ challenge testing is accepted for treatment validation, yet ...
Influence of femtosecond pulsed laser irradiation on bismuth germanium oxide single crystal properties
(Elsevier Ltd, 2016)
High quality bismuth germanium oxide single crystals were irradiated by a femtosecond pulsed laser beam of increasing power. Analyses performed on irradiated and unirradiated samples showed significant changes in transmittance, ...
Stochastic structure of annual discharges of large European rivers
(Versita, 2015)
Water resource has become a guarantee for sustainable development on both local and global scales. Exploiting water resources involves development of hydrological models for water management planning. In this paper we ...
