A new multidimensional crystallographic fast fourier transform
The Fast Fourier Transform (FFT) describes a well known set of algorithms that allows a fast evaluation of the Discrete Fourier Transform (DFT). In FFTs, the original sequence is replaced by the sum of a shorter sequence ...
Dsd variations on rain-rate estimate algorithms of x- band polarimetric radar and rainfall characterization in tropical environments using 2dvd, rain gauges and trmm data
Data from NASA TRMM satellite and rain gauges, the rain rate per hour was studied. The comparison took place in San Juan, Puerto Rico; when the Tropical Storm Jeanne passed over the island of Puerto Rico. Natural variations ...
Development of an administratrion module for the alert and reminder package of the nursing documentation system hpad
This document describes the development of a system to extend the functionality of the Alert and Reminder Module (ARM) from the nursing documentation system HPAD. The system introduces features to adapt the ARM to any ...
Development of an electro-thermal model for a multi-chip igbt power electronic module
A lumped parameter thermal model for a multi-chip power module is presented based in the physical and geometrical characteristics of the module. The model is developed using the thermal component approach. The model is ...
Design and characterization of log periodic rectangular slot ring antenna
This work studies two log-periodic rectangular slot ring antennas configurations. The first configuration is a CPW feed antenna. Return Loss ≤ - 10dB or VSWR ≤ 2 is achieve throughout 5.90 to 12.60GHz for this configuration, ...
