Piecewise linear detection for direct superposition modulation

Blast vibration modeling using linear superposition method

A linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in Sar-Cheshmeh copper mine, Kerman, Iran. A single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. The generated vibrations were measur...

Piecewise Linear Solution Paths for Para- metric Piecewise Quadratic Programs with Application to Direct Weight Optimization

Recently, pathfollowing algorithms for parametric optimization problems with piecewise linear solution paths have been developed within the field of regularized regression. This paper presents a generalization of these algorithms to a wider class of problems, namely a class of parametric piecewise quadratic programs and related problems. It is shown that the approach can be applied to the nonpa...

Sidelobe Deduction by Piecewise Non Linear Frequency Modulation Waveform

-The Linear Frequency Modulation (LFM) waveform is the most commonly and extensively used signal in practical radar system. This paper introduces a new scheme of Piecewise Nonlinear Frequency Modulation (PNFM) for generating good code sets. Each code set has good autocorrelation with small peak sidelobes and cross-correlation. A weighting function is usually applied in order to reduce the sidel...
