Planar curve offset based on circle approximation

An algorithm is presented to approximate planar offset curves within an arbitrary tolerance > 0. Given a planar parametric curve C(t) and an offset radius r, the circle of radius r is first approximated by piecewise quadratic Bézier curve segments within the tolerance . The exact offset curve Cr(t) is then approximated by the convolution of C(t) with the quadratic Bézier curve segments. For a p...

Probability of error calculation of OFDM systems with frequency offset

Orthogonal frequency-division multiplexing (OFDM) is sensitive to the carrier frequency offset (CFO), which destroys orthogonality and causes intercarrier interference (ICI). Previously, two methods were available for the analysis of the resultant degradation in performance. Firstly, the statistical average of the ICI could be used as a performance measure. Secondly, the bit error rate (BER) ca...

Normal cone approximation and offset shape isotopy

This work adresses the problem of the approximation of the normals of the offsets of general compact sets in euclidean spaces. It is proven that for general sampling conditions, it is possible to approximate the gradient vector field of the distance to general compact sets. These conditions involve the μ-reach of the compact set, a recently introduced notion of feature size. As a consequence, w...

Thermal Characteristics of Offset-Halves Bearing With Offset Factor

The Reynold’s equation and energy equation has been solved using finite difference method to study the effect of variation in offset factor on the performance characteristics such as oil-film temperatures, thermal pressures, load carrying capacity, power loss, and Sommerfeld’s number of offset-halves journal bearing. Numerical solution of Energy equation is achieved using Parabolic Temperature ...
