Measures for the degree of non-projectivity of dependency grammar have received attention both on the formal and on the empirical side. The empirical characterization of discontinuity in constituent treebanks annotated with crossing branches has nevertheless been neglected so far. In this paper, we present two measures for the characterization of both the discontinuity of constituent structures...

This paper proposes a single multiresolution framework for both surface "tting and discontinuities identi"cation in the surface reconstruction problem. In particular, the Mallat}Zhong wavelet transform modulus maxima (WTMM) representation is employed for representing the surface which allows the discontinuity detection and surface "tting to be carried out simultaneously in a cooperative manner ...

Throughout this thesis, there is an underlying assumption that the quality of a computer graphics image is important. This thesis reports research into computer image synthesis for obtaining this quality. The introduction of discontinuity meshing into existing radiosity techniques has enabled images to be produced at levels of previously unobtainable quality. However, discontinuity meshing is a...

The aim of this paper is to develop and test metrics to quantitatively identify technological discontinuities in a knowledge network. We developed five metrics based on innovation theories and tested the metrics by a simulation model-based knowledge network and hypothetically designed discontinuity. The designed discontinuity is modeled as a node which combines two different knowledge streams a...

OBJECTIVE To evaluate the usefulness of pure-tone audiometry, tympanometry, and liquid and acoustic reflex (AR) tests in the differential diagnosis of ossicular fixation and discontinuity. DESIGN A prospective clinical trial. SETTING Tertiary referral center. PATIENTS Thirty-nine patients (46 ears) undergoing operations at University of Tsukuba Hospital, Tsukuba, Japan, from 1990 through ...

Interactive rendering of soft shadows (or penumbra) in scenes with moving objects is a challenging problem. High quality walkthrough rendering of static scenes with penumbra can be achieved using pre-calculated discontinuity meshes, which provide a triangulation well adapted to penumbral boundaries, and backprojections which provide exact illumination computation at vertices very efficiently. H...

Through an exploration of theoretical physics, this paper suggests the need for regrounding natural science in phenomenological philosophy. To begin, the philosophical roots of the prevailing scientific paradigm are traced to the thinking of Plato, Descartes, and Newton. The crisis in modern science is then investigated, tracking developments in physics, science's premier discipline. Einsteinia...

We consider the problem of locating jumps in regression surfaces. A jump detection algorithm is suggested based on local least squares estimation. This method requires O(Nk) computations, where N is the sample size and k is the window width of the neighborhood. This property makes it possible to handle large data sets. The conditions imposed on the jump location curves, the jump surfaces and th...

We study discontinuity of the Lyapunov exponent. We construct a limit-periodic Schrödinger operator, of which the Lyapunov exponent has a positive measure set of discontinuities. We also show that the limit-periodic potentials, whose Lyapunov exponent is discontinuous, are dense in the space of limit-periodic potentials.
