ESTIMATION OF HYDRAULIC CONDUCTIVITY OF AN AREA USING STOCHASTIC FINITE ELEMENT METHOD

In this paper a stochastic finite element method is used to solve an inverse problem of groundwater flow.
The analysis provides the log hydraulic conductivity values of an aquifer. In this method, the adjoint finite element
equation is utilized for the solution of a transient groundwater flow problem. The results obtained from the maximum
likelihood estimate analysis are used as input to obtain the hydraulic conductivity values of the area using the cokriging
method.

AN OBJECT-ORIENTED FRAMEWORK FOR ECO-HYDRAULIC SIMULATION IN COASTAL ENGINEERING

The consideration of biological processes in hydro- and morphodynamic models is an
important challenge for numerical simulation in coastal engineering. Vegetation greatly
affects the hydro- and morphodynamic in coastal zones. This paper focused on the
presentation of an object-oriented holistic framework for eco-hydraulic simulation. The
numerical approximation is performed by a stabilized finite element method for hydro-
and morphodynamic processes, to solve the related partial differential equations, and by a
cell-oriented model for the simulation of ecological processes, which is based on a fuzzy

Study on corrosion simulation device for marine structural steel

A corrosion simulation device was studied using offshore long scale hanging specimens. An Ni–Cu–P steel specimen was studied by analysing its corrosion products and corrosion types. The appearance of the samples and the surface of the metallic substrate after the removal of the rust layer produced by these two methods were observed and compared after 470 days of exposure. The phase structure of the corrosion products under different marine environments were analysed and compared. It further indicated good correlation between the electrically connected hanging specimen method and the long scale hanging specimen method.

Precision Cold Forging – Innovative Methods for Working Pressure Reduction

Cold forging is a process in which the shape of metal is changed, by mechanical forces only, using the ductile properties of
metal. In forging, a metal work piece is plastically deformed by pressing, squeezing, or hammering forces – at temperatures ranging from ambient (cold forging) to 1,500 C (hot forging). During forging, the material should have sufficient flow properties and work at the upper limitof the material’s potential strength so as to
fill the die cavity shape without resulting incracks in the material.
