Accurate knowledge of the input torque and suitable models are essential to ensure reliability, but neither of them is currently available in commercial wind turbines. The present study
Understanding the strain transfer mechanism is required to interpret strain sensing results for fiber optic cables. The strain transfer mechanism for fiber optic cables embedded in cementitious materials has
Low-rate production began in early 1997, reaching full-rate production in September 1997, after the merger of McDonnell Douglas and Boeing the previous month. An
The U.S. Navy has embarked on a program to develop and install fiber optic (FO) sensors on hull, mechanical, and electrical equipment for control and monitoring purposes. Sensor reliability
This paper reviews the development of two common types of fiber optic sensors (fiber Bragg grating sensors and bend loss based fiber optic sensors) for geotechnical health monitoring,
Fiber Optic Gyroscopes (FOGs) are high-precision sensors that measure angular velocity (rotation) using the principles of light interference in a
Failure rate A(t), also called as hazard rate, failure intensity, force of mortality and instantaneous failure rate, describes the probability of failure per unit time at time 1, for the members of the original
ABSTRACT- The influence of various failure distribution laws on the reliability of fiber-optic data transmission systems (FODTS) components is analyzed. The article discusses the failure distribution

“Reliability is expressed as an expected lifetime or as an expected failure rate. The results cannot be used for specifications or for the comparison of the quality of different fibres.” The standards dictate a
In this paper we demonstrate an ultrasensitive superfine-resonance optical fiber sensor inserted into batteries for in situ and continuous monitoring of mass transports in electrolytes near the
Fiber optic systems are superior to metallic conductors because it is possible to transmit a signal that contains more information than is possible with a metallic conductor. In this chapter, we
