Novel fiber Bragg gratings (FBG) based settlement sensors are developed and the sensing performance is evaluated in
both the lab and field environments. The settlement is determined by precisely measuring the pressure of the water level
difference. The experimental results indicated that the sensor has good linearity, good repeatability and high accuracy in
the settlement measurements. The influence of temperature fluctuations on the sensor's performance is eliminated and
long-term test results proved the good stability of better than ±0.1% of the sensor. Such a FBG sensing system has been
applied to monitor the settlement of high-speed railways in practice.
The latest self-encoding resin bead is a novel technology for solid phase synthesis combinatorial library screening. A new encode-positional deconvolution strategy which was based on that technology been illustrated compared with positional scanning and iterative strategies. The self-encoding resin beads technology provides an efficient method for improving the high-throughput screening of combinatorial library.
