    Signal to Noise Ratio Estimations for a Volcanic Ash detection lidar

    In this paper we calculate the Signal-to-Noise (SNR) ratio of a 3-channel commercial volcanic ash detection system, (Raymetrics lidar model LR111-D300), already in operation for the Met Office organization. The methodology for the accurate estimation is presented for day and nighttime conditions. The results show that SNR values are higher than 10 for ranges up to 13 km for both nighttime and ...

    Molded Wide Double Arch Expansion Joint for Plastic/FRP Piping Systems

    Proco Style 262R molded wide double arch expansion joints have the lowest spring rates of any expansion joints currently on the market. They also boast low forces to deflect, and are built to withstand even the most rigorous piping system configurations. They allow for axial compression or axial extension, and lateral deflection as well as angular and torsional movements.
