Noise reduction in speech signals using a TMS320C31 digital signal processor
This paper describes a speech enhancement system (SES) based on a TMS320C31 digital signal processor (DSP) for real-time application. The SES algorithm is based on a modified spectral subtraction method and a new speech ...
A comparative study of MPPT strategies and a novel singlephase integrated buck-boost inverter for small wind energy conversion systems
This paper presents the analysis of some usual MPPT (Maximum Power Point Tracking) strategies intended for small wind energy conversion (up to 1kW) based on permanent magnet synchronous generators (PMSG), considering the ...
Energy conversion of porous media combustion into electric power

Computational Simulation Of Filtration Gas Combustion In A Porous Ceramic Annular Burner For Thermoelectric Power Conversion
A computational study on combustion in annular porous media and thermoelectric generation was performed. The reactor was composed of two types of porous media where flame stabilization was reached at the interface of them. ...
Differential mixer with NMOS/PMOS stack at switching stage
This paper proposes a novel differential mixer topology. The traditional stage of switching is replaced by a stack of NMOS and PMOS transistors combined. A design is given of a 900 MHz down-conversion mixer using a 0.35 ...
Concentration dependence of the infrared photoluminescence of Pr3+ in fluoroindate glasses
Infrared photoluminescence properties are investigated for Pr3+ containing fluoroindate glasses with formula (mol% compositions) (99-x)[40InF3-20SrF2-20BaF2-20ZnF2]:xPrF3 (x= 0.1, 0.2, 0.5, 1.0 and 2.0 mol%). Different ...
