Quantification of Respiratory Regularity by Time-Frequency Analysis

Regularity and unitarity of bilinear time-frequency signal representations

Two structural properties of bilinear timefrequency representations (BTFR’s) of signals are introduced and studied. The definition of these properties is based on a linear-operator description of BTFR’s. The first property, termed regularity, has important implications with respect to the recovery of signals from their BTFR outcome, the derivation of other bilinear signal representations from a...

Real-time damage detection of bridges using adaptive time-frequency analysis and ANN

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

Relationship of Air Pollution and Daily Hospital Admissions Due to Respiratory Disease: A Time Series Analysis

Introduction: Air pollutants and respiratory diseases have a significant relationship and cause major health problems. Low attention has been paid to the daily hospital admissions due to the presence of pollutants in desert cities such as Yazd city, Iran. Therefore, this study aimed to investigate the short-term relationship between air pollution and daily hospital admissions due to respiratory...
