Latest Patents

Lei Ni holds a patent for an "Urban non-metallic pipeline leakage location method." This method involves several steps, including determining whether a leak occurs in a pipeline through numerical simulation law analysis or a Markov chain-based flow analysis method. For a leaking pipeline, he establishes an inverse-transient control equation for non-metallic pipeline gas leakage. This process allows for the collection of pressure and flow rate data from various measuring points over time. By substituting this data into the control equation, he can analyze the experimental data effectively. Furthermore, he defines a nonlinear programming problem with a least squares criterion and applies a sequential quadratic programming method to minimize the objective function, ultimately determining the size and position of the leakage. Lei Ni has 1 patent to his name.
