The bank-of-filters spectrum analysis model is commonly used in the extraction of acoustic features for automatic speech recognition. The most critical component in the analysis model is a bank of bandpass filters. In this paper, we studied a data-driven approach to designing a hank of “optimal” filters of various shapes discriminatively so that the recognition error of a task is minimized. Thr...

The stimulus to growth that occurs when cells attach to the substratum can be studied with small adhesive islands. Large numbers of these islands can be grouped together into arrays made up of various sizes, and the response of cells to incubation on these arrays allows the anchorage stimulus to be measured. Past work has shown that single isolated cells can be stimulated to proliferate under t...

We fabricated a variety of reduced graphene oxide (RGO) nanoring arrays using Au@Pt nanoplates as a pattern mask. RGO nanoflakes were assembled into a 2-dimensional assembly at the water-oil interface, and then various shapes of Au@Pt nanoplates were utilized as a pattern mask in order to convert the RGO into circular, triangular, and hexagonal RGO nanorings.

Shape blending determines the in-between shapes that provide the gradual transformation of one shape into another. It is usually considered a two-step problem: the correspondence problem and the interpolation problem. This paper presents a solution to the interpolation of transforming one triangular mesh model into another triangular mesh based on their intrinsic definitions. Rather than consid...

Equilibrium Wulff shapes and interfacial energies of two-dimensional ‘‘crystals’’ on a triangular lattice are considered. Asymptotic approximations are constructed for both the shapes and energies in the limit T→0 where crystals are close to perfect hexagons, and the limit T→Tc ~critical temperature! where crystals have near-circular shapes. The intermediate temperature region is studied numeri...

A MEMS thermal actuator is a micromechanical device that typically generates motion by thermal expansion. In this paper we have studied the thermal expansion of different shapes of thermal actuator and implemented using COMSOL tool.Different shapes are designed and analyzed.Rectangular, triangular and U shaped actuator is designed and implemented.

The shape of a weightless spinning liquid droplet is governed by the balance between the surface tension and centrifugal forces. The axisymmetric shape for slow rotation becomes unstable to a nonaxisymmetric distortion above a critical angular velocity, beyond which the droplet progresses through a series of 2-lobed shapes. Theory predicts the existence of a family of 3- and 4-lobed equilibrium...

This paper puts forward 3D model retrieval method based on normal-angle histogram. The method firstly makes the pretreatment for 3D model, and defines the calculation method of the normal at every vertex of the triangular mesh in 3D model and the included angle among the triangular meshes. Then it classifies the triangular mesh in accordance with the normal at three vertexes of the triangular m...
