Radiomagnetotelluric two-dimensional forward and inverse modelling accounting for displacement currents

Numerical Modelling of Two-dimensional and Axisymmetric Gravity Currents

A series of two-dimensional, axisymmetric and three-dimensional numerical flow simulations using an Implicit Large Eddy Simulation (ILES) are carried out for gravity-driven fluid flows, the results are compared directly with experiments undertaken to test the model. Two-dimensional results show that the Large Eddy algorithm is successful in modelling a gravity current’s large scale structure. E...

On the forward and inverse displacement of spatial parallel manipulators

In engineering applications, the singularity, and the forward and inverse displacement of spatial parallel manipulators have received a great deal of attention. This paper presents a new simple but effective methodology to investigate these problems based on the analysis of the degree of freedom (DoF) of the spatial parallel manipulator. Through numerical method, the singularity and the forward...

Seismic Amplification of Peak Ground Acceleration, Velocity, and Displacement by Two-Dimensional Hills

There are valuable investigations on the amplification effects of the topography on the seismic response in the frequency domain; however, a question is that how one can estimate the amplification of time domain peak ground acceleration (PGA), peak ground velocity (PGV), and peak ground displacement (PGD) over the topographic structures. In this study, the numerical approach has been used for t...

Three-Dimensional Simulation of Qeshm Channel Currents

Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using C...
