Detects inspection

In a study conducted on 13 patients with chronic psychiatric conditions who had received therapeutic dosage of benzodiazepines for several months, Sramek et al.3 were able to detect diazepam (0.2-1.6 ng/mg), but alprazolam and lorazepam were not detected. Inspection of diazepam results were not suggestive of a correlation between dosage and hair concentration. [Pg.273]

The spectram acquired in this way can he used for characterization of the inspected object or detection of flaws in it. Since the spectram gathered by the modem instrument can consist... [Pg.105]

The performance of the classifier has been verified using a number of practical applications, such as civil engineering [3], inspection of aerospace composite structures, ball bearings and aircraft multi-layer structures. Here we present shortly some results, focusing on detection of disbonds in adhesively joint multi-layer aerospace structures using Fokker Bond Tester resonance instrument, details can be found in [1]. [Pg.107]

During the inspection of an unknown object its surface is scanned by the probe and ultrasonic spectra are acquired for many discrete points. Disbond detection is performed by the operator looking at some simple features of the acquired spectra, such as center frequency and amplitude of the highest peak in a pre-selected frequency range. This means that the operator has to perform spectrum classification based on primitive features extracted by the instrument. [Pg.109]

Representative set of weldments was examined site welds (with pearlitic type weld metal) and two types of site weld repair zones with different welding technologies using Cr-Ni filler metals and Ni-based alloy. Results of AUGUR 4.2 inspection were compared with manual ultrasonic inspection ones in terms of defect detection, characterization, positioning and sizing in order to estimate correlation between these data. [Pg.195]

All defects detected by manual inspection were detected by AUGUR 4.2 system. [Pg.195]

There were cases in which the extensive defect, detected by manual inspection, was cut into two or three isolated defects with small length by AUGUR 4.2 . [Pg.195]

AUQUR 4.2 revealed a number of small-size defects with the height of about 2 mm did not detected by manual inspection. These flaws were located near the boundaries of cut-off zone of repaired welds and likely had originated after near-boundary passes of repair welding [3]. [Pg.196]

Usually all the flaw detectors in service have two channels to detect defects of a rope the LMA and LF channels. The inspection information is recorded by a chart recorder or by a tape recorder. [Pg.335]

Inspection of load - carrying structures and mounting hardwares, the defects detection under side platings and dielectric shells in their attaching points to the load - carrying structures. [Pg.345]

Active thermography is a contactless NDE technique that consists in the detection of infrared emission after the transient thermal excitation of the inspected structure. [Pg.393]

The eombination in a compact system of an infrared sensor and a laser as excitation source is called a photothermal camera. The surface heating is aehieved by the absorption of the focused beam of a laser. This localisation of the heating permits a three-dimensional heat diffusion in the sample to be examined. The infrared (IR) emission of the surface in the neighbourhood of the heating spot is measured by an infrared detector. A full surface inspection is possible through a video scanning of the excitation and detection spots on the piece to test (figure 1). [Pg.393]

As to inspections performed on light-alloy castings, the expert group agrees on the specifications of marginal conditions that should be met with regard to the required IQI detectability. [Pg.439]

We use the X or gamma rays power penetrating to detect possible heterogeneities in inspected pieces. These rays are absorbed by the matter crossed, essentially by the photoelectrical effect, (fig. 02). [Pg.525]

A method that would enable detection and classification of the bone content in 100% of the incoming frozen fish blocks in real time without delaying the production line was desired. An obvious solution to this was the use of X-ray inspection. X-ray inspection however requires the integration of a highly sensitive inspection equipment with the corrosive atmosphere associated with food processing as well as the tough restrictions imposed by the health authorities regarding irradiation of food. [Pg.587]

Surface Crack Detection Using Magnetic Particle Techniques and Penetrant Inspection Method. [Pg.628]

Increasing production and therefore inspection rates may increase the stress to the inspector and result in a decreasing reproducability and flaw detection rate. In addition by replacing the human inspector by a fully automatic image processing tremendeous cost savings are achieved. [Pg.628]

If the inspection equipment can be run under stable and reproducable conditions due to the QAP the basis for using a camera system for flaw detection is given.The camera system consists of CCD-cameras and a pattern recognition software. Up to four CCD-cameras can be served by one PC. One shot of the part may be copied up to 16 times in the computer and this theoretically enables the crack determination with 16 different parameter sets. [Pg.630]

Additionally the distance between the camera and inspection-surface has to be controlled. The software for flaw detection was developped in a way that enables the camera of measuring different areas of the parts with different sensitivities in a single step and to cover areas that not have to be inspected. [Pg.631]

Detection of this particle accumulation has so far been done visually. To make the particles more easily visible, they have been chemically treated in order to make them light up or flouresce when struck by an ultraviolet light. The operator sits in a darkened room in which the test pieces are illuminated by ultraviolet light. Cracks show up very clearly and in principle this method of inspection is acceptable. Despite the effiency of this method it is well known that a large number of defective pieces pass this test. Why is it so ... [Pg.639]

Quantitative determined visual recognition for usual inspections, indicate that for indications with lengths over about 1.5 mm tbe probability of recognition is about 100 %. This is also applied to the penetrant inspection. This does not include the so called "human factor" which means that it cannot be guaranted that the inspector detects all indications for instance not always observing the inspection surface with full concentration. [Pg.669]

The method was applied for determination of the quality of the detection media on test pieces following the type testing of the European standard [4] in order to check the validity of the method. The other application was the determination of the visibility in dependance of the variations of the inspection parameters (application of the detection medium, magnetization, inclination, viewing conditions) in a range which may appear in the practical inspections. The results leads to conclusions on the visibility level which is a measure of the probability of recognition for the indication that means of the reliability of the method. [Pg.669]

It was assumed that the inspection will be carried out always with the same quality controlled detection medium. [Pg.676]
