The Delaunay triangulation and the weighted Delaunay triangulation are not uniquely defined when the input set is degenerate. We present a new symbolic perturbation that allows to always define these triangulations in a unique way, as soon as the points are not all coplanar. No flat tetrahedron exists in the defined triangulation. The perturbation scheme is easy to code; It is implemented in cg...

The purpose of this paper is to present a new type of dynamic balancing system, having a driving solution of the rotating part based on magnetic interactions. The magnetic system also plays the role of an elastic bearing. In the first part of the article is presented the technical solution which allows the dynamic balancing evaluation depending on the radial displacement between two disks with ...

This paper presents on-line perturbation tracking and intrusion removal techniques which are designed to accommodate delays which occur due to monitoring activities. These accommodations eliminate the effect of monitoring intrusion on the execution behavior and the scheduling of the monitored computation. By maintaining an adjusted time view, the intrusion removal system preserves the execution...

This paper is an attempt to measure our understanding of volcano/atmosphere interactions by comparing a box model of potential volcanogenic aerosol production and removal in the stratosphere with the stratospheric aerosol optical depth over the period of 1979 to 1994. Model results and observed data are in good agreement both in magnitude and removal rates for the two largest eruptions, El Chic...

We investigate the hard nonresonant excitation of the forced Duffing equation with a positive damping parameter E. Using the symbolic manipulation system MACSYMA, a computer algebra system. we derive the two term perturbation expansion by the method of multiple time scales. The resulting approximate solution is valid for small values of the coefficient e As the damping parameter e increases, th...

Humans are able to rapidly adapt their movements when a visuomotor or other systematic perturbation is imposed. However, the adaptation is forgotten or unlearned equally rapidly once the perturbation is removed. The ultimate cause of this unlearning remains poorly understood. Unlearning is often considered to be a passive process due to inability to retain an internal model. However, we have re...

ABSTRACT We provide perturbation theory predictions for the H i intensity mapping power spectrum multipoles using Effective Field Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. Assuming survey specifications typical proposed interferometric experiments like Canadian Hydrogen Observatory and Radio transient Detector PUMA, realistic ranges validity mod...

Human walking must be flexible enough to accommodate many contexts and goals. One form of this flexibility is locomotor adaptation: a practice-dependent alteration to walking occurring in response to some novel perturbing stimulus. Although studies have examined locomotor adaptation and its storage by the CNS in humans, it remains unclear whether altered movements occurring in the leg contralat...
