Application of Trend Detection Methods in Monitoring Physiological Signals

چکیده
This paper presents a comparative study of various trend detection methods developed using fuzzy logic, statistical, and regression techniques. A new method that uses noise rejection fuzzy clustering is also proposed in the paper to enhance the performance of trend detection methodologies. The comparative investigation has produced systematic guidelines for the selection of a proper trend detection method for different application requirements. This paper has resulted from work on military applications of on-line trend analysis, such as monitoring of wounded soldiers by first-response medical staff at the battlefield and high-acceleration protection of fighter jet pilots. Efficient trend detection methods can provide early warnings, severity assessments of a subject’s physiological state, and decision support for firstresponse medical attendants. Representative physiological variables such as blood pressure, heartbeat rate, and ear opacity are considered in this paper.

Proposed new signal for real-time stress monitoring: Combination of physiological measures
Human stress is a physiological tension that appears when a person responds to mental, emotional, or physical chal-lenges. Detecting human stress and developing methods to manage it, has become an important issue nowadays. Au-tomatic stress detection through physiological signals may be a useful method for solving this problem. In most of the earlier studies, long-term time window was considere...

متن کاملApplication of Wavelet Transform as a Signal Processing Method for Defect Detection using Lamb Waves: Experimental Verification
A Lamb wave-based crack detection method for aluminum plates health monitoring is developed in this paper. Piezoelectric disks are employed to actuate and capture the Lamb wave signals. The position of crack is assumed to be aligned with the sensor and actuator. Extraction of high quality experimental results of lamb wave propagation in a plate-like structure is considerably complicated due to...

Stress has affected human’s lives in many areas, today. Stress can adversely affect human’s health to such a degree as to either cause death or indicate a major contributor to death. Therefore, in recent years, some researchers have focused to developing systems to detect stress and then presenting viable solutions to manage this issue. Generally, stress can be identified through three differe...
