Response Properties of Piezoelectric AE Sensor on CFRP Laminate by Using Simulate AE Source.

AE Source Orientation by Plate Wave Analysis

Lead breaks (Hsu-Neilsen source) were used to generate simulated acoustic emission signals in an aluminum plate at angles of 0, 30, 60, and 90 degrees with respect to the plane of the plate. This was accomplished by breaking the lead on slots cut into the plate at the respective angles. The out-of-plane and in-plane displacement components of the resulting signals were detected by broad band tr...

Acoustic Emission Sensor Networking System (AE-SNS)

Recent advances in embedded systems and associated software tools have given a new dimension in the development of miniature intelligent sensor networking approach to develop state of the art NDT instruments. A new concept is realized to develop multi channel modular acoustic emission system suitable for field applications such as structural integrity assessment. Conventional acoustic emission ...

Collection and Discrimination of AE Signals from Tank Ships using an intrinsically safe certified AE Sensor System

Equipment for use in potentially explosive atmosphere is subject to particular requirements on safety and quality as determined by a number of Standards. For use in Europe, such equipment needs to conform to the EC directive 94/9/EC, also called “ATEX Directive”. The conformity must be certified by a socalled ATEX Certificate. In the frame of the EC-funded research project „Corrosion testing of...

Chromosome Isolation by Flow Sorting in Aegilops umbellulata and Ae. comosa and Their Allotetraploid Hybrids Ae. biuncialis and Ae. geniculata

This study evaluates the potential of flow cytometry for chromosome sorting in two wild diploid wheats Aegilops umbellulata and Ae. comosa and their natural allotetraploid hybrids Ae. biuncialis and Ae. geniculata. Flow karyotypes obtained after the analysis of DAPI-stained chromosomes were characterized and content of chromosome peaks was determined. Peaks of chromosome 1U could be discriminat...
