Detection and Diagnosis of Motor Stator Faults using Electric Signals from Variable Speed Drives [PDF]

, 2015
Motor current signature analysis has been investigated widely for diagnosing faults of induction motors. However, most of these studies are based on open loop drives.

Assortative matching through signals [PDF]

We model signalling in two-sided sequential search with heterogeneous agents and transferable utility. Search via meetings is time-consuming and thereby costly due to discounting. Search via signals is costless, so that agents can avoid almost all search

Numerical methods for decomposition of 2D signals by rotation and wavelet techniques [PDF]

, 2001
Segregation of desirable and undesirable components in a signal given by measurements is a broad subject with many applications of huge importance.

Evaluating arrhythmias in ECG signals using wavelet transforms.

, 2000
Recent work has attempted to utilize wavelet techniques in the analysis of biomedical signals including ECGs. Here, the authors present an energy-based method of interrogating the ECG in VF using high-resolution, log-scale continuous wavelet plots.

Dissipative Advertising Signals Quality even without Repeat Purchases [PDF]

Economists have emphasized the role of dissipative advertising and price as signals of quality. Most works, however, limit the number of types to two options: high and low quality.

Performance Assessment of Navigation Signals in Realistic Multipath Environments

, 2008
A major error source within global navigation satellite systems, such as the Global Positioning System or the future European satellite navigation system Galileo, comes from multipath, the reception of additional signal replica due to reflections caused ...

A functional data analysis approach for modelling frequency‐modulated tonal sounds in animal communication

Methods in Ecology and Evolution
Frequency modulation (FM) is believed to play a major role in encoding information in tonal vocal communication. However, most studies aimed at investigating acoustic variability rely on the manual measurement of acoustic parameters, and the ...

EVOLUTIONARY THEORIES OF MORALITY AND THE MANIPULATIVE USE OF SIGNALS

Zygon, 1994
. Several attempts have recently been made to explain moral systems and moral sentiments in light of evolutionary biological theory. It may be helpful to modify and extend this project with the help of a theory of communication developed by ethologists.

Developing new techniques to analyse and classify EEG signals [PDF]

, 2018
A massive amount of biomedical time series data such as Electroencephalograph (EEG), electrocardiography (ECG), Electromyography (EMG) signals are recorded daily to monitor human performance and diagnose different brain diseases.
