A new semi-empirical model for proton induced SEU is presented. For estimating the energy deposited by the protons in the sensitive volumes of the devices the model uses the measured spectra of surface barrier detectors (SBD) with the same thicknesses of t ...
Following the optical amplifier position in the transmission link, the four-wave mixing (FWM) induced crosstalk is increased up to two times the optical gain. A simple approximate expression of the crosstalk penalty is derived and compared with exact resul ...
We present a simple technique to precisely and continuously adjust the resonance wavelengths of long-period cladding-mode-coupled gratings without strongly affecting the coupling strength. The main principle of this method is based on the strong dependence ...
We propose a method to simulate muscle deformation in real-time, still aiming at satisfying visual results; that is, we are not attempting perfect simulation but building a useful tool for interactive applications. Muscles are represented at 2 levels: the ...
In many applications, industry has tried to develop sinusoidal supply for brushless DC (BLDC) motors. This paper describes a method that still keeps a simple 2 phases-on sensorless method and achieves sinusoidal supply, which is needed to avoid speed oscil ...
A simple system for optical and microwave signals analysis based on the optical sampling technique is presented. It is novel in requiring only low-frequency detection and electronic components. This is made possible by the use of a commercially available L ...
The incommensurate structure of gamma-bis(n-propyl-ammonium) tetrachloromanganate(II) (gamma-PAMC) at 365 K has been determined in the superspace group Abma(alpha01)000. Main reflections and satellites up to second order have been included. Besides the har ...
Low-frequency losses in weakly anharmonic cubic centrosymmetric crystals as a function of permittivity are estimated using phonon kinetics approach. It is shown that very steep dependencies up to the fifth power of permittivity (epsilon'' is-proportional-t ...
The stopping cross section, the straggling parameter, and three higher moments over the energy-loss cross section have been evaluated for a moving point charge interacting with atomic hydrogen. The aim was to estimate the accuracy of predictions based on f ...
The electrodynamics of a high-T(c) superconductor with a network of numerous weak links (the Josephson medium) in the low-field mixed state have been analysed. The AC response to an electromagnetic wave is governed by the motion of vortices of very large s ...
