We present an FPGA-synthesizable version of a pseudo-random pulse generator that can be used to emulate radioactive source activity. It is intended for debugging real-time digital pulse processing ...

The isotope samarium-146 decays into neodymium-142; this radioactive decay has been used to date moon rocks and Martian meteorites but had never been used on Earth rocks, O’Neil says.

Abstract: This technical note addresses the stability analysis of linear systems governed by continuous-time difference equations with multiple delays. We propose new sufficient conditions for L 2 ...
