In the last decade several techniques have been developed to enhance geophysical data in order to extract subtle features that reflect the structural geology of the area. These techniques include curvelet, ridglet and wavelet analysis. Although these techniques provide a powerful tool in extracting linear features from geophysical data, they lack the power to resolve curvilinear or circular fea...

What we tend to call postmodernism in literature today is usually characterized by intense self-reflexivity and overtly parodic intertextuality. In fiction this means that it is usually metafiction that is equated with the postmodern. Given the scarcity of precise definitions of this problematic period designation, such an equation is often accepted without question. What I would like to argue ...

The lattice Boltzmann method (LBM) has recently become an alternative and promising computational fluid dynamics approach for simulating complex fluid flows. Despite its enormous success in many practical applications, the standard LBM is restricted to the lattice uniformity in the physical space. This is the main drawback of the standard LBM for flow problems with complex geometry. Several app...

different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.  in the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. the flow hydraulics incl...
