The “Butterfly” Wrap

Topological and Structural Properties of Butterfly-de-Bruin: A Product Network of Wrap-Around Butterfly and de Bruin Networks

This paper proposes and analyzes a novel interconnection network called Butterfly-de-Bruijn, which is a Product of wrap-around Butterfly and de Bruijn Networks. This new network, as a product of Butterfly (Bn) and de Bruijn (Dn) networks of degree n and denoted as BnDn, provides the connection among n2 2 nodes with a diameter of |_3n/2_|, same as butterfly network, and a constant node degree of...

On a Product Network of Enhanced Wrap-Around Butterfly and de Bruijn Networks

The topological structures of conventional Interconnection networks, such as Mesh, have recently been adopted in emerging areas such as wireless sensor networks, the pervasive computing and the Internet of Things. In this paper, we propose and analyze a novel Interconnection network topology called Enhanced Butterfly-de-Bruijn (denoted as EBnDn), which is the Product of Enhanced wrap-around But...

Wrap Shading

Shading models that wrap around the hemisphere have been used to approximate subsurface scattering, area light sources, and softer reflectance profiles. We generalize a specific technique that has been used in games by parameterizing the amount of wraping while retaining important mathematical properties. We include details on how to incorporate theses models with spherical harmonic lighting. 1...

Investigation of the Flow and Cavitation in a Butterfly Valve

Since knowledge on hydrodynamic torque of a butterfly valve is very important for butterfly valve design, its hydrodynamic torque is investigated in this paper. In reality, the investigation of the loss coefficient and torque from some experiments will take a long time and a lot of money. This paper presents a statistical study of the flow past the butterfly valve in a static analysis using com...
