We present a study of the relationship between the changes in the shape of the human ear due to jaw movement and acoustical feedback (AF) in hearing aids. In particular, we analyze the deformation field of the outer ear associated with the movement of the mandible (jaw bone) to understand its effect on AF and identify local regions that play a significant role. Our data contains ear impressions...

This paper reviews shearography and its applications for testing of aircraft composite structures and honeycomb-based specimen. Shearography is a laser-based interferometry in conjunction with the digital imaging processing technique for full-field measurement of surface deformation. It reveals defects in an object by looking for defect-induced deformation anomalies. It does not require special...

This paper presents a new approach to the estimation of the deformation of an isotropic Gaussian random field on R based on dense observations of a single realization of the deformed random field. Under this framework we investigate the identification and estimation of deformations. We then present a complete methodological package—from model assumptions to algorithmic recovery of the deformati...

In the last years, phase field method has established itself for simulation of various problem types, especially in fields microstructure evolution and transformations as well fluid dynamics. Concerning first two cases, usually a constant, deformation-independent, surface energy is considered. this work, however, deformation-dependent elasticity according to [5] will be incorporated into theory...

Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

Chie C. Poon Andrew C. Tam IBM Almaden Research Center 650 Harry Road San Jose, California 95120 Abstract. We investigate deformation of stainless steel and ceramic specimens with a precision of the order of tens of nanometers using a pulsed laser beam. Such a technique is useful, for example, in a process of removing distortions on magnetic head components to achieve a better contact between t...

In this paper we present a non-rigid registration method to align pre-operative MRI (preMRI) with resected intra-operative MRI (iMRI) to compensate for brain deformation during tumor resection. This method formulates the registration as a three-variable (point correspondence, deformation field and resection region) functional minimization problem, in which point correspondence is represented by...

In this paper, we demonstrate how deformation patterns of leaves and fruits in growing and drying processes can be described via the inhomogeneous field theory. The distorted deformation of ribbed leaves and the ridge formation on fruit surfaces can be understood as the energy-minimizing mechanical buckling patterns. The swelling and de-swelling induced instabilities of various membrane structu...
