Uncertainty reduction in water distribution network modelling using system inflow data
(Urban Water Journal, 2009)
In water distribution network (WDN) modelling, nodal demand is the sum of flows taken by users associated with a computational node. User demands are not fixed in time; rather they are stochastic. Hence, nodal demand is a ...
Overland flow and pathway analysis for modelling of urban pluvial flooding
(Journal of Hydraulic Research, 2009)
Research on improving an overland flow model is presented for urban pluvial flooding under the dual-drainage concept where sewer flow dynamically interacts with overland flow. This occurs during heavy storms when the sewer ...
Boundary element-dual reciprocity formulation for bound electron states in semiconductor quantum wires
(Computer Physics Communications, 2008)
Using the boundary element dual reciprocity method-multi-domain (DRM-MD) a bound electron states and corresponding wave functions in semiconductor quantum wires embedded in a matrix were considered. The single circular and ...
SIPSON - Simulation of interaction between pipe flow and surface overland flow in networks
(IWA Publishing, 2005)
The new simulation model, named SIPSON, based on the Preissmann finite. difference method and the. conjugate gradient method, is presented in the paper. This model simulates conditions when the hydraulic capacity of a sewer ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
Simulation of transcritical flow in pipe/channel networks
(ASCE - American Society of Civil Engineers, 2004)
Using finite difference methods in conjunction with the reduced momentum equation and applying boundary condition structure inherent to subcritical flow to all regimes, is an approach that enables efficient numerical ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Advanced Composite Materials, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Fracture of reinforced concrete beams subjected to three point bending
(International Journal of Damage Mechanics, 2003)
The present paper investigates deformation of three point bent reinforced concrete (RC) beams analytically (using fracture mechanics), computationally (using finite element method) and experimentally. As the applied force ...
Contribution to transient analysis of inelastic steel frames with semi-rigid connections
(Engineering Structures, 2008)
Dynamic behavior of multistory flexibly connected steel frames under earthquake excitations is studied in this paper. The numerical model that simultaneously includes nonlinear connection behavior, member yielding and ...
Punching failure mechanism at edge columns of post-tensioned lift slabs
(Engineering Structures, 2008)
A test program designed to evaluate the punching shear strength of unbonded post-tensioned lift flat slabs at edge columns is described. Three isolated specimens, which represented a part of the edge panel in the vicinity ...
