Leak Detection Methods for Pipelines
IFAC Proceedings Volumes, 1984For the early detection and localization of small leaks in pipelines a nonlinear adaptive state observer and a special correlation technique are developed, based on pressure and flow measurements at the pipeline inlet and outlet. Simulations and experiments show the results for a gas and a liquid pipeline.

On the scheduling of leak detection personnel
Computers & Chemical Engineering, 2004Due to recent environmental regulations concerning the release of volatile organic compounds (VOCs), a virtual army of testing personnel has been assigned the task of detecting and repairing faulty equipment leaks. In this work, we develop a strategy for the cost-effective allocation of these testing personnel.

Memory leak detection in Plumbr
Software: Practice and Experience, 2014SummaryPlatforms with automatic memory management, such as the JVM, are usually considered free of memory leaks. However, memory leaks can happen in such environments, as the garbage collector cannot free objects, which are not used by the application anymore, but are still referenced.

A System for Detection of Pressure Leaks
2020This work presents an original software and hardware system whose objective is to detect pressure leaks. Two methods for detection of leaks are considered: the first one is based on an industrial vision system, the second one on a proprietary ultrasonic sensor using Fast Fourier Transformation (FFT). Automation of the measuring process has been done by

Real leaks and real leak detection
Vacuum, 1970A summary of the theory for simple pore and permeation type real leaks is given, and a proposal is presented for the detection of real leaks to a sensitivity of 10−12 STP cc per second using a probe gas and a partial pressure analyzer as the leak detection system.

LEAK DETECTION AND LEAK LOCATION IN UNDERGROUND PIPELINES1
International Oil Spill Conference Proceedings, 1997ABSTRACT The use of passive acoustic techniques to detect and locate leaks in underground pipelines that carry pressurized liquids is being investigated in a joint research program between the Department of Defense (DoD), the Department of Energy (DOE), and the U.S. Environmental Protection Agency (EPA).

Vacuum, 1965
Abstract While continuous advances in the design of vacuum components and in the techniques of construction have gradually reduced the incidence of “built-in” leaks in vacuum systems, the parallel development of leak detectors has facilitated the detection of smaller leaks until, at the present time, the lowest pressure attainable in a metal vacuum ...
