Effect of Internal Reinforcing on Impact Axial Collapse Behavior of Hat-Shaped Tubular Structure
A hollow steel structure with a hat cross-section was axially compressed under impact or quasistatic conditions. The hat height and hat width were 40 mm. The thickness was 0.6, 0.8, and 1.0 mm.

Synthetic Spectrum Approach for Brillouin Optical Time-Domain Reflectometry
We propose a novel method to improve the spatial resolution of Brillouin optical time-domain reflectometry (BOTDR), referred to as synthetic BOTDR (S-BOTDR), and experimentally verify the resolution improvements.

A Circular Microstrip Antenna Sensor for Direction Sensitive Strain Evaluation
In this paper, a circular microstrip antenna for stress evaluation is studied. This kind of microstrip sensor can be utilized in structural health monitoring systems. Reflection coefficient S11 is measured to determine deformation/strain value.

A novel compliance measurement in radial arteries using strain-gauge plethysmography [PDF]
[[abstract]]We propose a novel method for assessing the compliance of the radial artery by using a two-axis mechanism and a standard positioning procedure for detecting the optimal measuring site.

Strain measurement using oscillator circuit sensor with high sampling frequency
A strain measurement system based on astable multivibrator using CMOS inverter has been developed. This system could omit an amplifier, filter and A/D converter unlike conventional Wheatstone bridge type sensor, because strain is measured by counting ...
