A two-microphone transfer function (TMTF) method is adapted to a numerical framework to compute the radiation and input impedances of three-dimensional vocal tracts of elliptical cross-section. In its simplest version, the TMTF method only requires measuring the acoustic pressure at two points in an impedance duct and the postprocessing of the corresponding transfer function. However, some cons...

We discuss two recent topics on heavy-ion quasi-elastic scattering at energies around the Coulomb barrier. The first topic is an application of quasi-elastic scattering at deep-subbarrier energies to extracting the surface diffuseness parameter of the nucleus-nucleus potential. The second topic is a coupled-channels analysis for the quasi-elastic barrier distribution for the 70Zn + 208Pb reacti...

In this paper, we further develop the theory of complete mixability and joint mixability, we provided sufficient conditions for certain univariate distributions with oneside unbounded support that are not joint mixable and complete mixable. An alternative proof to a result of Wang and Wang (2016) which related to the joint mixability of elliptical distributions with the same characteristic gene...

A computational fluid dynamic (CFD) study compared two configurations of distal anastomosis of 12 mm Contegra conduit: conventional 'circular' vs. oblique 'elliptical' anastomosis extended on the left PA, evaluating pressure and velocity profiles, and shear stress, from PA origin to the bifurcation. 'Elliptical' anastomosis provides larger (=54% difference) cross-sectional area than 'circular' ...

We study the conditions under which and how an imposed cluster of fixed colloidal particles at prescribed positions triggers crystal nucleation from a metastable colloidal fluid. Dynamical density functional theory of freezing and Brownian dynamics simulations are applied to a two-dimensional colloidal system with dipolar interactions. The externally imposed nucleation clusters involve colloida...

We present Easy Mesh Cutting, an intuitive and easy-to-use mesh cutout tool. Users can cut meaningful components from meshes by simply drawing freehand sketches on the mesh. Our system provides instant visual feedback to obtain the cutting results based on an improved region growing algorithm using a feature sensitive metric. The cutting boundary can be automatically optimized or easily edited ...

We propose a novel personal identification method, named Thermal-ID, which utilizes human body temperature as a source of identifying information. Thermal-ID is expressed by the temperature difference generated by partially covering the surface of the body with thermal barrier material (e.g., cutout urethane foam-coated aluminum foil). The aim is to positively identify a subject with minimal di...

A novel flexure hinge named half circular-elliptical hybrid flexure hinge was presented. Based on Castigliano’s Displacement Theorem, the compliance equations of the novel flexure hinge were formulated. A computer aided analysis and parametric design program of the half circular-elliptical hybrid flexure hinge was developed by VC++6.0. A specific half circular-elliptical hybrid flexure hinge wa...

In this paper, we consider a new class of quasi variational inequalities involving three operators, which is called the extended general quasi variational inequality. It is shown that the extended general quasi variational inequalities are equivalent to the fixed problems. This equivalence is used to suggest and analyze some iterative methods for solving the extended general quasi variational i...

In this paper we proposed the estimation of the characteristic impedance, effect of dispersion, and the effective dielectric constant of Coplanar Waveguide (CPW) using conformal mapping theory and performances are analyzed. Numerically efficient and accurate formulae based on the conformal mapping method for the analysis of coplanar waveguide structures are presented. The analysis formulas for ...
