The prime reason for this interest has been the need for stringent standards for quality control for safe operation of nuclear and other industrial installations. The IAEA has successfully carried out a number of programmes, including technical cooperation projects (national and regional) and coordinated research projects having NDT was an important part. Through these programmes, many people in IAEA Member States have received training, leading to the establishment of national certifying bodies responsible for training and certification of NDT personnel. Consequently, many Member States have achieved self- sufficiency in this area. There has long been a realization that well established training guidelines and related books are needed to guide the IAEA experts involved in this training programme and to achieve a level of international uniformity and harmonization of training materials and consequently competence of NDT personnel. The IAEA has issued numerous syllabi for these training courses, beginning in 1987 with the publication of IAEA-TECDOC-407, Training Guidelines in Non-destructive Testing Techniques, containing syllabi for five basic methods (i.e. liquid penetrant testing, magnetic particle testing, eddy current testing, radiographic testing, ultrasonic testing). To accommodate advancements in NDT technology, updated versions of this publication were issued in 1991, 2002 and 2008. The current version, IAEA-TECDOC- 628/Rev.3 (2013), includes information on additional and more advanced NDT methods. The next logical step was to compile textbooks and training manuals in accordance with these syllabi. Manuals on visual, liquid penetrant, magnetic particle, leak and eddy current testing have already been published in the IAEA’s Training Course Series. These play a vital role in the training and certification of NDT personnel in Member States. Compilation of the present book on ultrasonic testing is a continuation of that effort. The IAEA wishes to express its appreciation to S. Ahmed (Pakistan) for his many contributions to the current publication. The IAEA officer responsible for this publication was P. Brisset of the Division of Physical and Chemical Sciences.

  • Types of Software Testing
    Types of Software Testing We would be glad to have feedback from you. Drop us a line, whether it is a comment, a question, a work proposition or just a hello. You can use either the form below or the contact details on the rightt. Contact details [email protected] +91 811 386 5000 1 Software testing is the way of assessing a software product to distinguish contrasts between given information and expected result. Additionally, to evaluate the characteristic of a product. The testing process evaluates the quality of the software. You know what testing does. No need to explain further. But, are you aware of types of testing. It’s indeed a sea. But before we get to the types, let’s have a look at the standards that needs to be maintained. Standards of Testing The entire test should meet the user prerequisites. Exhaustive testing isn’t conceivable. As we require the ideal quantity of testing in view of the risk evaluation of the application. The entire test to be directed ought to be arranged before executing it. It follows 80/20 rule which expresses that 80% of defects originates from 20% of program parts. Start testing with little parts and extend it to broad components. Software testers know about the different sorts of Software Testing. In this article, we have incorporated majorly all types of software testing which testers, developers, and QA reams more often use in their everyday testing life. Let’s understand them!!! Black box Testing The black box testing is a category of strategy that disregards the interior component of the framework and spotlights on the output created against any input and performance of the system.

  • Nonlinear Ultrasound Spectroscopy for Chemical Quantification
    Nonlinear Ultrasound Spectroscopy for Chemical Quantification Jonathan R. Dion Department of Chemistry McGill University, Montreal Quebec, Canada August 2011 A thesis submitted to McGill University in partial fulfillment of the requirements of the degree of Doctor of Philosophy © Jonathan R. Dion, 2011 Abstract Analyte quantification is an area of great practical interest for biomedical and commercial applications. Measurement in highly scattering media such as tissue, blood, and other biological fluids is challenging using conventional spectroscopic methods. Likewise, measurement of compounds on-line or in opaque containers can be extremely challenging. This thesis presents general approaches for analyte quantification in liquids by the frequency analysis of ultrasound waves. Initially, this research focused on the quantification of analytes using dispersive hydrogel sensors. These sub-micron hydrogels vibrate at characteristic resonance frequencies when exposed to ultrasound. The resonance frequencies of the sensors could be modulated by generating molecularly imprinted pockets that would recognize and bind to molecules. Changes in the measured ultrasound frequency spectrum upon binding could then be detected. Using this approach, quantification of theophylline between 10 μM and 6.1 mM was shown. Improvements in analyte quantification using ultrasound were made by designing hydrogel sensors coupled to antibodies. The high affinity of antibodies for a specific antigen allowed the quantification of acetaminophen between 3.5 nM and 20.8 nM. The highly selective antibodies were also demonstrated to allow acetaminophen determination in a variety of biological media. Though the ultrasound frequency profiles change in the different media, frequencies used for multilinear determination of the analyte were ii clustered in certain regions of the spectrum.

  • Audio and Tactile Interfaces to Mobility Aids for the Blind
    Interfaces for multi-sensor systems for navigation for the blind Penny Probert, David Lee and Gordon Kao Robotics Research Group, Department of Engineering Science, University of Oxford, 19 Parks Road, Oxford, OX1 3PJ, ENGLAND Tel: +44-1865-273926 Fax: +44-1865-273908 [email protected], [email protected] ABSTRACT This paper describes work towards a multi-sensor system to assist blind people to move around an urban or indoor environment. The communication of navigation information is constrained by both the type of information imparted and, in many ways more crucially, by the type of information which real sensors can extract. In this paper we describe the use of ultrasound to provide two types of information: first the low level directional information which may be provided currently by a guide dog and then information on features to allow the blind person to locate and direct themselves within the environment. A directional system with a simple vibrator interface is described and its performance assessed by a group of users. Finally we discuss the possibility of feature extraction for navigation by recognition and give some results using frequency modulated sonar. Keywords: ultrasound, mobility aids, blindness, human interface 1. BACKGROUND AND STRUCTURE OF PAPER Vision is by far the most important sense for most people, and trends in virtual reality and computer interfaces reflect this emphasis. Sighted people appreciate detailed images and are able to abstract relevant data from images with ease, and the challenge in virtual reality is not in abstracting the data but providing enough detail at sufficient speed.
