Interpreting Dye Test Results for Improved Drip Irrigation Management for the Mulched Vegetable-Production Systems in South Florida
Published 2014-07-01“… On-farm dye tests provide simple, low-cost methods to understand how water and dissolved nutrients (e.g., nitrogen) will move within beds at a given farm. If it is not feasible for the grower to conduct an on-farm dye test, results from a dye test with similar site characteristics—including region, soil type, bed geometry, and drip tape—can be used. …”

旋转叶片异步振动参数辨识方法及试验验证
Published 2021-01-01“…Based on the principle of blade tip timing( BTT) and the vibration principle of one degree of freedom,the parameter identification algorithm of rotating blade asynchronous vibration is established by using all phase FFT( apFFT) and least square method.The algorithm is verified by numerical simulation,and the test parameter and empirical value of the rationality for sensor layout are given.The tests of asynchronous vibration parameter identification were launched on a fan rotor,while high pressure nitrogen was used to shock the blades to produce single frequency absolute occupancy vibration.Results show that the method for asynchronous vibration identification could accurately identify blade vibration parameters,and the vibration frequencies of all blades obtained are exactly the same.Frequency identification accuracy is high with the maximum relative error of 1.12% using strain analysis frequency as a baseline.Results verify that the method of asynchronous vibration parameter identification is correct.…”
