For example, if noise-predictive detection is performed in conjunction with a maximum a posteriori (MAP) detection algorithm such as the BCJR algorithm [13] then NPML and NPML-like detection allow the computation of soft reliability information on individual code symbols, while retaining all the performance advantages associated with noise ...
The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...
It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. [1] It typically uses a vacuum chamber in which a sealed container filled with helium is placed. Helium leaks out of the container, and the rate of the leak is detected by a mass ...
A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.

The Van Gelder Studio is a recording studio at 445 Sylvan Avenue, Englewood Cliffs, New Jersey, United States. [4] Following the use of his parents' home at 25 Prospect Avenue, Hackensack, New Jersey , for the original studio, Rudy Van Gelder (1924–2016) moved to the new location for his recording studio in July 1959.
Doug White working at the studio in 2008. The studio originated in White's parent's basement, where he and his band mates at the time built a small facility to do their own recording. White's band's name was the Watchmen, a reference to the Alan Moore comics. Because only his band was recording at the time, the studio itself inherited the name.
