Block volumes are generally estimated by analyzing the discontinuity spacing measurements obtained either from the scan lines placed over the rock exposures or the borehole cores. Discontinuity spacing measurements made at the Mesozoic limestone quarries in Karaburun Peninsula were used to estimate the average block volumes that could be produced from them using the suggested methods in the lit...

We investigate a modiication of Horn and Schunck's approach which leads to a better preservation of ow discontinuities. It replaces the quadratic smoothness term by a nonquadratic one. Energy minimization by steepest descent leads to a system of two nonlinear diiusion{reaction equations with a single common nonlinear diiusivity. This enables us to make use from techniques for nonlinear diiusion...

Some biological systems detect the rate of change in a stimulus rather than the stimulus itself only. We suggest that the immune system works in this way. According to the discontinuity theory of immunity, the immune system responds to sudden changes in antigenic stimulation and is rendered tolerant by slow or continuous stimulation. This basic principle, which is supported by recent data on im...

Studies have shown that the position of a target stimulus is misperceived owing to ongoing motion. Although static forces (fixation, landmarks) affect perceived position, motion remains the overwhelming force driving estimates of position. Motion endpoint estimates biased in the direction of motion are perceptual signatures of motion's dominant role in localization. We sought conditions in whic...

Abstract In this paper we argue that financing decisions contribute to the zero-earnings discontinuity. We find a discontinuity in distribution of earnings before tax and special items, but not interest which suggests expense contributes To investigate role discontinuity, further show there was level debt issues around zero contemporaneous with also recent disappearance is coincident issuance d...

Most prior research on the tendency for groups to be less cooperative than individuals (the interindividual-intergroup discontinuity effect) has used the Prisoner's Dilemma Game (PDG). Experiment 1 examined the discontinuity effect with 3 additional matrices: Chicken, Leader, and Battle of the Sexes (BOS). Unlike the PDG, these matrices are characterized by correspondence of outcomes. The disco...

This paper studies the discontinuity in the behavior of neighboring integral curves. Discontinuity is measured by a number of selected attributes of the integral curves. A variety of attribute fields are defined. The attribute value at any given spatio-temporal point in these fields is assigned the attribute of the integral curve that passes through this point. This encodes the global behavior ...

In recent years discontinuity meshing has become an important part of mesh-based solutions to the global illumination problem. Application of this technique accurately locates all radiance function discontinuities in the scene and is essential for limiting visual artifacts. In an environment containing m edges there are O(m) D and D discontinuities. With a typical scene this can result in many ...

Regression Discontinuity Design with Covariates In this paper, the regression discontinuity design (RDD) is generalized to account for differences in observed covariates X in a fully nonparametric way. It is shown that the treatment effect can be estimated at the rate for one-dimensional nonparametric regression irrespective of the dimension of X. It thus extends the analysis of Hahn, Todd, and...

An approximate Riemann solver of Godunov type for ideal relativistic magnetohydrodynamic equations (RMHD) named as HLLC (“C” denotes contact) is developed. In HLLC the Riemann fan is approximated by two intermediate states, which are separated by the entropy wave. Numerical tests show that HLLC resolves contact discontinuity more accurately than the Harten-Lax-van Leer (HLL) method and an isola...
