Characterization of Signals

چکیده
We present a couple of new algorithmic procedures for the detection of ridges in the modulus of the (continuous) wavelet transform of one-dimensional signals. These detection procedures are shown to be robust to additive white noise. We also derive and test a new reconstruction procedure. The latter uses only information from the restriction of the wavelet transform to a sample of points from the ridge. This provides with a very eecient way to code the information contained in the signal.

Affective Visual Stimuli: Characterization of the Picture Sequences Impacts by Means of Nonlinear Approaches
Introduction: The main objective of the present study was to investigate the effect of preceding pictorial stimulus on the emotional autonomic responses of the subsequent one. Methods: To this effect, physiological signals, including Electrocardiogram (ECG), Pulse Rate (PR), and Galvanic Skin Response (GSR) were collected. As these signals have random and chaotic nature, nonlinear dynamics...
متن کاملPURIFICATION AND CHARACTERIZATION OF THE CLONED HUMAN GM-CSF GENE EXPRESSED IN ESCHERICHIA COLI
The human granulocyte-macrophage colony stimulation factor (hGM-CSF) gene was cloned in the pET 23a( +) expression vector under the control of strong bacteriophage T7 transcription and translation signals. The hGM-CSF gene was transferred into E. coli strainBL21 (DE3)pLysS andIPTG was used for induction of GM-CSF gene. Production of the target protein was obtained as revealed by ELISA and ...

متن کاملCloning and molecular characterization of TaERF6, a gene encoding a bread wheat ethylene response factor
Ethylene response factor proteins are important for regulating gene expression under different stresses. Different isoforms for ERF have previously isolated from bread wheat (Triticum aestivum L.) and related genera and called from TaERF1 to TaERF5. We isolated, cloned and molecular characterized a novel one based on TdERF1, an isoform in durum wheat (Tri...
متن کاملWavelet-based Analysis for Pulse Period of Earthquake Ground-motions
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...
