Impact of biannual rossby waves on the Indian Ocean Dipole
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Topex/Poseidon sea surface height anomalies during 1993-2002 are decomposed using 2-D finite impulse response filters which showed biannual Rossby waves (BRWs) in the equatorial Indian Ocean (peak at 1.5 degrees S) and in ...
Comparative analysis of synchronization algorithms based on PLL, RDFT and Kalman Filter
This paper discusses the main characteristics and presents a comparative analysis of three synchronization algorithms based respectively, on a Phase-Locked Loop, a Kalman Filter and a Discrete Fourier Transform. It will ...
Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
Programmable Multichannel Sine Wave Generator for a C-MEMS Based Dielectrophoretic Filter-Edición Única
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2015)
Nova proposta de critério de retenção para dimensionamento de filtros têxteis
The designs of filters made by granular material or textile are mainly based on empirical or semi empirical retention criteria according to Terzaghi proposal, which compares particle diameter of the soil base with the ...
Implementation of filters for image pre-processing for leaf analyses in plantations
In this work an image pre-processing module has been developed to extract quantitative information from plantation images with various degrees of infestation. Four filters comprise this module: the first one acts on ...
Estimated errors in a global gravity wave climatology from GPS radio occultation temperature profiles
In a previous paper by Schmidt et al. (2008), from CHAllenging Minisatellite Payload (CHAMP) Global Positioning System (GPS) radio occultation data, a comparison was made between a Gaussian filter applied to the "complete" ...
Frequency-adjustable positive sequence detector for power conditioning applications
This paper proposes a novel and simple positive sequence detector (PSD), which is inherently self-adjustable to fundamental frequency deviations by means of a software-based PLL (Phase Locked Loop). Since the proposed ...
