Enhanced leak detection in water distribution systems using GFCC-based signal processing techniques
Physics OpenLeak detection in water distribution systems remains a significant challenge, especially for small-scale leaks masked by noise. This study proposes an advanced signal processing approach using Gammatone Frequency Cepstral Coefficients (GFCC) combined ...

Use of PVDF Wire Sensors for Leakage Localization in a Fluid-Filled Pipe
Sensors, 2020 The detection and location of pipeline leakage can be deduced from the time difference between the arrival leak signals measured by sensors placed at the pipe access points on either side of a suspected leak.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Pressure Change Leak Detection Based on Lagrange Interpolation Formula
SICE Journal of Control, Measurement, and System Integration, 2017 The pressure change method of leak testing has the serious disadvantage of being susceptible to ambient temperature change. Two or more successive leak tests are typically performed to eliminate the error caused by such change.

Intensive leak standards for helium leak detection
Journal of Physics: Conference Series, 2021 Abstract The article discusses the main reasons for the demand for gas leak standards with a flow range of 5⋅10-7 to 5⋅10-4 Pa⋅m3/s, for helium leak detection. The high flow Leak Standards Vactron VKT are presented.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Leak Detection and Location Based on ISLMD and CNN in a Pipeline
IEEE Access, 2019 The key to leak detection and location in water supply pipelines is signal denoising and feature extraction. First, in this paper, an improved spline-local mean decomposition (ISLMD) is proposed to eliminate noise interference.

Data Leak Detection as a Service [PDF]
, 2013 We describe a network-based data-leak detection (DLD) technique, the main feature of which is that the detection does not reveal the content of the sensitive data. Instead, only a small amount of specialized digests are needed. Our technique – referred to as the fuzzy fingerprint detection – can be used to detect accidental data leaks due to human ...
