Identification of vibration sources

Applied Acoustics, 2000
Abstract The problem addressed is the identification of force distributions exciting structures from the knowledge of measured flexural displacements. The method, called “Force Analysis Technique” (FAT), is based on the computation of the force distribution, the second member of the equation of motion, which is discretized by a finite difference ...

Portable source identification device

SPIE Proceedings, 2005
U.S. Customs and Border Protection (CBP) is the primary enforcement agency protecting the nation’s ports of entry. CBP is enhancing its capability to interdict the illicit import of nuclear and radiological materials and devices that may be used by terrorists.

Source identification with GLAST

AIP Conference Proceedings, 2007
With more than 50 % of unidentified sources, the third EGRET catalogue reflects the complexity of source identification in the GeV domain. In that context, we developed a dedicated GLAST ScienceTool dubbed gtsrcid for the general purpose of source identification.

Perchlorate Sources, Source Identification And Analytical Methods

2008
Given the wide range of anthropogenic and natural perchlorate sources, the remediation practitioner should be aware of effective source identification and analytical methods to determine the origin and extent of perchlorate contamination. Characterization issues discussed in this chapter include: (1) anthropogenic and natural sources of perchlorate and

Source-specific system identification

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
Many applications in audio communication require the identification of Loudspeaker-Enclosure-Microphone Systems (LEMS) with multiple inputs and outputs. The according computational complexity typically grows at least proportionally along the number of acoustic paths, which is the product of the number of loudspeakers and the number of microphones ...

Identification of Source Rocks

1978
The derivation of petroleum from nonreservoir rocks is a well-established fact. Rocks that are, or may become, or have been able to generate petroleum are commonly called source rocks. The presence of insoluble organic matter (kerogen) is a primary requisite for an active or a potential source rock.

Infrared Source Identification Tables

1990
Several infrared sources listed in the Catalogue (Part 3) have optical nebular counterparts. Hα emission nebulae (HII regions) and dark clouds are frequently associated with dusty regions emitting primarily at far-infrared wavelengths (60 and 100 microns).

Identification of flicker sources

8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002
The paper deals with a novel method proposed to identify the flicker sources providing the possibility of the separation of the flicker effect of the individual consumers connected to the same busbar.

Selective structural source identification

Journal of Sound and Vibration, 2018
In the field of acoustic source reconstruction, the inverse Patch Transfer Function (iPTF) has been recently proposed and has shown satisfactory results whatever the shape of the vibrating surface and whatever the acoustic environment. These two interesting features are due to the virtual acoustic volume concept underlying the iPTF methods.
