Data classification: Dimensionality reduction using combined and non-combined multidimensional projection techniques
(2018-12-13)
Dimensionality Reduction is a commonly used method to reduce the number of dimensions of data. In this work, we verified its influence in classification process using combinations of projection techniques as dimensionality ...
Second-order statistics for diversity-combining, techniques in Nakagami-fading channels
(Institute of Electrical and Electronics Engineers (IEEE), 2001-11-01)
Exact and closed-form expressions for the level crossing rate and average fade duration are presented for the M branch pure selection combining (PSC), equal gain combining (EGC), and maximal ratio combining (MRC) techniques, ...

Time-frequency analysis combining wavelets and the envelope technique for fault identification in rotary machines
(2013-03-18)
Nowadays the method based on demodulation by envelope finds wide application in industry as a technique for evaluation of bearings and other components in rotating machinery. In recent years the application of Wavelets for ...
Improved estimation of the particle size distribution from combined light scattering measurements
(Research Signpost, 2010)
Light scattering (LS) techniques, such as single-angle dynamic light scattering (DLS), elastic light scattering (ELS), and turbidimetry (T), are frequently used to estimate the particle size distribution (PSD) of a polymeric ...
