The Jacobi last multiplier for difference equations
Jacobi Last Multiplier first order lineal partial differential difference equations
2012/2/29
We present a discretization of the Jacobi last multiplier, with some applications to the computation of solutions of difference equations.
An Optical Fibre Pulse Rate Multiplier for Ultra-low Phase-noise Signal Generation
Optical Fibre Ultra-low Phase-noise Signal
2011/9/6
In this letter we report on an all optical-fibre approach to the synthesis of ultra-low noise microwave signals by photodetection of femtosecond laser pulses. We use a cascade of Mach-Zehnder fibre in...
Silicon Photo-Multiplier radiation hardness tests with a beam controlled neutron source
Silicon Photo-Multiplier beam controlled neutron source
2010/3/16
We report radiation hardness tests performed at the Frascati Neutron Generator on silicon Photo-Multipliers, semiconductor photon detectors built from a square matrix of avalanche photo-diodes on a si...
Improved Faddeev-Jackiw quantization of the electromagnetic field and Lagrange multiplier fields
Faddeev-Jakiw method constraint quantization electromagnetic field Lagrange multiplier
2009/8/14
We use the improved Faddeev-Jackiw quantization method to quantize the electromagnetic field and its Lagrange multiplier fields. The method's comparison with the usual Faddeev-Jackiw method and the Di...
