Developability of ruled surfaces based on C-Bézier basis
2010 Edition, Volume 10, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we discuss developable surfaces of ruled surfaces based on C-Bézier basis, which named C-developable surfaces. This method has three important advantages. No (nonlinear) charactering equations...

A Group of Orthogonal Basis Based on UE-Bézier Basis
2011 Edition, June 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

UE-Bezier (unified and extended Bezier) basis is the unified form of Bezier-like bases, including polynomial Bezier basis, trigonometric polynomial and hyperbolic polynomial Bezier basis. Similar to the original Bezier-like...

Designing and realization on surface syntactic analysis based on rule and statistical approach
2008 Edition, June 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Language is the main carrier of social information. In order to make use of the information existing in the form of natural language, we should extract and analyze it with the technique of dealing with natural language. In dealing with natural language, syntax analysis...

Recirculation Surfaces for Flow Visualization
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a formal approach to the visual analysis of recirculation in flows by introducing recirculation surfaces for 3D unsteady flow fields. Recirculation surfaces are the loci where massless particle integration returns to its starting point after some variable, finite...

Geometric Design of Developable Bezier and B-spline Parametric Surfaces
2007 Edition, Volume 3, July 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Using the concept of duality between points and planes in 3D projective space, an explicit and efficient method of computer-aided design for developable surfaces based on Bezier and B-spline basis functions is proposed. By the result that a...

Uniform illumination for nonplanar surface based on freeform surfaces
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The shapes of target surfaces are nonplanar on many occasions such as undulating road and roof of the tunnel, while the lighting quality generated by traditional non-imaging optical lenses still needs to be further improved. As a result, a novel method is proposed for...

ω-Bezier
2007 Edition, October 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A new kind of B+¬zier-like basis with a frequency parameter, called ω-Bezier basis, is presented. It unifies and extends the B+¬zier basis, C-B+¬zier basis and H-B+¬zier basis defined over polynomial space, trigonometric polynomial space and...

Droplet Jumping on Superhydrophobic Copper Oxide Nanostructured Surfaces
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Condensation has been widely explored because of its importance in numerous applications including water desalination, water harvesting, power generation, and thermal management. Previous studies have shown that the enhancement in condensation heat transfer can be achieved with the...

Wideband Cross Polarization Rotation based on Reflective Anisotropic Surfaces
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The article presents a new design to broaden polarization conversion ratio (PCR) bandwidth utilizing reflective surfaces. The proposed design is based on anisotropic surfaces for linearly polarized electromagnetic (EM) waves. The combination of a traditional...

Characteristic Mode Equations for Impedance Surfaces
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Characteristic mode formalism is presented for closed surfaces modelled with the impedance boundary condition (IBC). The characteristic equations are expressed in terms of the electric, magnetic and combined field integral operators (EFIO, MFIO and CFIO). Similarly as for perfectly...
