In recent years, installation of plates in canal beds have been considered for sedimentation control and bed load reduction at canal intake. These planes, called submerged vanes, are different in dimensions. They are installed at intakes in-group with reasonable distance from each other. Presence of these vanes at intakes initiate transverse shear stress on river bed and causes sediment transpo...

The impact of heterogeneous forest canopies and complex terrain on the horizontal distortion inflow is studied. Large-Eddy Simulation (LES) neutral Atmospheric Boundary Layer (ABL) flow performed for a wind farm in Sweden three cases associated with different directions at range static yaw misalignment (≃±6∘) where control system not activated. ground topography properties numerical modeling ar...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

Image interpolation is a common problem in imaging applications. However, most interpolation algorithms in existence suffer visually the effects of blurred edges and jagged artifacts in the image to some extent. This paper presents an adaptive feature preserving bidirectional flow process, where an inverse diffusion is performed to sharpen edges along the normal directions to the isophote lines...

As information systems (IS) are increasingly able to create highly engaging and interactive experiences, the phenomenon of flow is considered a promising vehicle to understand pre-adoptive and post-adoptive IS user behavior. However, despite a strong interest of researchers and practitioners in flow, the reliability, validity, hypothesized relationships, and measurement of flow constructs in cu...

Image interpolation is a common problem in imaging applications. However, most interpolation algorithms in existence suffer visually to some extent the effects of blurred edges and jagged artifacts in the image. This paper presents an adaptive feature preserving bidirectional flow process, where an inverse diffusion is performed to enhance edges along the normal directions to the isophote lines...

A new type of glyph is introduced to visualize unsteady flow with static images, allowing easier analysis of time-dependent phenomena compared to animated visualization. Adopting the visual metaphor of radar displays, this glyph represents flow directions by angles and time by radius in spherical coordinates. Dense seeding of flow radar glyphs on the flow domain naturally lends itself to multi-...

Hydrodynamics analyses as a part of APEX (Advanced Power Extraction) study shows the possibility of applying swirling thick liquid walls to innovative confinement concepts such as Field Reversed Configuration (FRC), Spherical Torus (ST) and Heavy-Ion Fusion (HIF). This paper addresses the design and the hydrodynamic aspects of fusion relevant swirling flow including 3-D velocity distribution, v...

unsteady flow through non - homogeneous and anisotropic porous media can be modeled by a partial differential equation.' this-equation cannot be solved analytically. hence, numerical methods. such as the finite element and the finite difference methods might be employed. in this study a mathematical model has been developed using the fully implicit finite difference method with control vol...
