In order to model climate data time series that often contain periodic variations, trends, and sudden changes in mean(mean shifts, mostly artificial), this study proposes a hybrid‐domain(HD) algorithm, which incorporates a time domain test and a newly developed frequency domain test through an iterative procedure that is analogue to the well known backfitting algorithm.  1, record 1, English, - backfitting%20algorithm

The data is then analyzed by a spectrum estimation algorithm to obtain the most accurate representation of the acquired signal into frequency bands. To achieve real-time spectrum-sensing implementations, the algorithm needs to have low computational costs and be able to detect the small, quiet periods defined in various standards.  2, record 2, English, - spectrum%20estimation%20algorithm

[A filter used] to remove random noise while preserving high frequency features (edges).  3, record 5, English, - gamma%20filter

The Gamma filter performs gamma map filtering. Gamma filtering is primarily used on radar data to remove high frequency noise(speckle) while preserving high frequency features(edges). The Gamma Map filter was first proposed by Kuan.... Lopes modified the Kuan Map filter by assuming a gamma distributed scene and setting up two thresholds. The gamma filter size ranges from 1 to 11. Different filter sizes will greatly affect the quality of processed images. If the filter is too small, the noise filtering algorithm is not effective. If the filter is too large, subtle details of the image will be lost in the filtering process. A 7x7 filter usually gives the best results.... The GAMMA filter performs spatial filtering on each individual pixel in an image using the grey level values in a square window surrounding each pixel. The dimensions of the filter must be odd, and can be from 3x3 to 11x11 pixels.  2, record 5, English, - gamma%20filter

Gamma Filter yields the best smoothing and despeckling. Moreover, it seems to keep the edges without blurring the minimum. Eight textures are applied, based on the cooccurrence matrix. These textures include mean, variance, homogeneity, contrast, dissimilarity, entropy, second moment, and correlation.  4, record 5, English, - gamma%20filter

The prototype helium speech descrambler uses digital signal processing(DSP) to transform the diver's speech, thus counteracting the effect of heliox.... A sampling frequency of 16 KHz or greater captures the full frequency range of the diver's speech. The algorithm uses high order linear prediction to deconvolve and scale the vocal tract components while maintaining the original pitch of the diver's voice.  1, record 6, English, - helium%20speech%20descrambler

Pour concevoir le prototype du désembrouilleur de discours, on a procédé au traitement numérique de signal (DSP) afin de transformer le discours du plongeur et contrecarrer ainsi l'effet de l'héliox. [...] Un échantillon de fréquence de 16 KHz ou davantage capte la gamme entière de fréquence du discours du plongeur. Pour l'algorithme on se sert d'une prédiction linéaire de grande intensité afin de «déconvolutionner» et d'équilibrer les composantes vocales tout en préservant la tonalité de la voix du plongeur.  1, record 6, French, - d%C3%A9sembrouilleur%20de%20discours
