In the present study, a spectral finite element method is developed for free and forced transverse vibration of Levy-type moderately thick rectangular orthotropic plates based on first-order shear deformation theory. Levy solution assumption was used to convert the two-dimensional problem into a one-dimensional problem. In the first step, the governing out-of-plane differential equations are tr...

Electromagnetic articulograph (EMA) provides movement data of sensors attached to a few flesh points on different speech articulators including lips, jaw, and tongue while a subject speaks. In this work, we quantify the amount of information these flesh points provide about the vocal tract (VT) shape in the mid-sagittal plane. VT shape is described by the air-tissue boundaries, which are obtain...

Object-based video representation, such as the one suggested by the MPEG-4 standard, offers a framework that is better suited for object-based video indexing and retrieval. In such a framework, the concept of a “key frame” is replaced by that of a “key video object plane.” In this paper, we propose a method for key video object plane selection using the shape information in the MPEG-4 compresse...

HICKS, GREGORY PHILIP. Modeling and Control of a Snake-like Serial-link Structure (Under the direction of Kazufumi Ito). The topic considered is the modeling and control of a snake-like serial-link structure. The system is assumed to have torque controls about the joints, is considered to lie in an isotropic plane, and is assumed to interact with this plane in a manner which adheres to some sui...

Many applications require a computer representation of 2D shape, usually described by a set of 2D points. The challenge of this representation is that it must not only capture the characteristics of the shape but also be invariant to relevant transformations. Invariance to geometric transformations, such as translation, rotation and scale, has received attention in the past, usually under the a...

Mesoporous silica nanoparticles with a two-dimensional center-rectangular (plane group c2mm) lattice and coiled elliptical channels have been synthesized; the new synthetic route also allows simple control over the lattice dimensions and the elliptical shape of the channels.

In this paper, we focus on the real-time 3D shape reconstruction of an object moving in a wide area(e.g. a dancing human). To efficiently record dynamically changing 3D object shape, the real-time 3D shape reconstruction and active tracking are required. For the real-time 3D shape reconstruction, we propose a parallel plane-based volume intersection method. By implementing the algorithm on a PC...

As a pedagogical exercise, we derive the shape of a particularly elegant pop-up card design, and show that it connects to a classically studied plane curve that is (among other interpretations) a caustic of a circle.

A novel topological segmentation of retinal images represents blood vessels as connected regions in the continuous image plane, having shape-related analytic and geometric properties. This paper presents topological segmentation results from the DRIVE retinal image database [SAN∗04].

Gessel and Viennot have developed a powerful technique for enumerating various classes of plane partitions [GVl, 21. There are two fundamental ideas behind this technique. The first is the observation that most classes of plane partitions that are of interest--either by association with the representation theory of the classical groups, or for purely combinatorial reasons+an be interpreted as c...
