speakerʼs phonation at two fundamental frequencies were analyzed with a 3D pattern matching method to obtain displacement and angular changes of the thyroid and cricoid cartilages. Results show displacement of the two cartilages relative to each other in 3D. The largest difference between 110 Hz and 165 Hz was found to be 1.2 mm horizontally and 0.6 mm vertically with respect to the translation...

The need for a simple, routinely applicable method for morphologic analysis of maxillary arch in cleft patients resulted in development of a new original, objective and computerized method. The authors present the rationale and procedure of this method which is extremely suitable for clinical documentation, follow up and clinical investigation of cleft patients. The descriptive factors are expr...

We present new O(n) algorithms to compute very accurate SVDs of Cauchy matrices, Vandermonde matrices, and related \unit-displacement-rank" matrices. These algorithms compute all the singular values with guaranteed relative accuracy, independent of their dynamic range. In contrast, previous O(n) algorithms can potentially lose all relative accuracy in the tiniest singular values. LAPACK Working...

Several ultrasound-based imaging modalities have been proposed for image guidance and monitoring of High-Intensity Focused Ultrasound (HIFU) surgery. However, accurate localization and characterization of the effective region of treatment (thermal lesion) remain the obstacles in the clinical implementation of HIFU ablation. Harmonic motion imaging for focused ultrasound (HMIFU) is a novel HIFU ...

The oculomotor system maintains saccade accuracy by adjusting saccades that are consistently inaccurate. Four experiments were performed to determine the relative contribution of background and target postsaccadic displacement. Unlike typical saccade adaptation experiments, we used natural image scenes and masked target and background displacements during the saccade to exclude motion signals f...

The effect on the transport properties of fractures of a relative shear displacement ~u of rough walls with complementary self-affine surfaces has been studied experimentally and numerically. The shear displacement ~u induces an anisotropy of the aperture field with a correlation length scaling as u and significantly larger in the direction perpendicular to ~u. This reflects the appearance of l...

Behavioral simulation using high-level hardware description languages (HDLs) is becoming increasingly relevant for mixed-domain MEMS simulation. In this paper three issues which impact the convergence and simulation time in MEMS behavioral simulations are addressed. First, velocity and displacement are compared for the choice of the across variable in nodal simulation. The through variable is f...

This paper presents an analysis of present and future hydrological conditions at the Forsmark site in Sweden, which has been proposed as the site for a geological repository for spent nuclear fuel. Forsmark is a coastal site that changes in response to shoreline displacement. In the considered time frame (until year 10 000 AD), the hydrological system will be affected by landscape succession as...

This paper presents an affine model for 3-D motion and shape recovery using two perspective views and their relative 2-D displacement field. The 2-D displacement vectors are estimated as parameters of a 2D affine model that generalizes standard block matching by allowing affine shape deformations of image blocks and affine intensity transformations. The matching block size is effectively found ...

This work presents a methodology for detecting human retina images suspect of glaucoma based on the measurement of displacement of the vascular bundle caused by the growth of the excavation or cup. The results achieved are due to the relative increase in size of the cup or excavation that causes a displacement of the blood vessel bundle to the superior, inferior and nasal optic disc areas. The ...
