Non-destructive techniques are used widely in the metal industry in order to control the quality of materials. Eddy current testing is one of the most extensively used non-destructive techniques for inspecting electrically conductive materials at very high speeds that does not require any contact between the test piece and the sensor. This paper includes an overview of the fundamentals and main...

Abstract. An information diagnostic system is currently being developed. The system is based on electromagnetic non-destructive testing and uses a matrix magnetic converter for revealing flaws and forecasting the reliability of machines and mechanisms. The considered algorithm, which analyses magnetic nondestructive testing results, uses a dynamic type matrix magnetic transducer. To estimate cr...

Mycotoxin contamination in certain agricultural systems have been a serious concern for human and animal health. Mycotoxins are toxic substances produced mostly as secondary metabolites by fungi that grow on seeds and feed in the field, or in storage. The food-borne Mycotoxins likely to be of greatest significance for human health in tropical developing countries are Aflatoxins and Fumonisins. ...

In nondestructive testing to locate the faults we send an ultrasonic signal and measure the resulting vibration at di erent points To describe and combine the uncertainty corresponding to di er ent measurements and fuzzy estimates we used fuzzy logic As a result we get reasonably simple computa tional models which lead to as good fault detection as the known more complicated models I Nondestruc...

GMR sensors are widely used in many industrial segments such as information technology, automotive, automation and production, and safety applications. Each area requires an adaption of the sensor arrangement in terms of size adaption and alignment with respect to the field source involved. This paper deals with an analysis of geometric sensor parameters and the arrangement of GMR sensors provi...

Several important technological and economic trends are shaping the research on non-destructive testing techniques. They include increasing computerisation and automation, fusion of different NDT methods, new market expansions, use of the techniques as a process control tool, and a proliferation of merges, consolidations and joint ventures. Other important factors such as the development of new...

Pulsed eddy current (PEC) non-destructive testing and evaluation (NDT&E) has been around for some time and it is still attracting extensive attention from researchers around the globe, which can be witnessed through the reports reviewed in this paper. Thanks to its richness of spectral components, various applications of this technique have been proposed and reported in the literature covering ...

In this paper, the determination of defects in concrete structures using an ultrasound technique is discussed. A diagnostic model for concrete pillars by means of Multi Layer Perceptron neural networks is developed to locate and classify the defects. Finite Elements numerical techniques have been used to model a concrete pillar of specified size (i.e., rectangular cross section and 2 meters in ...
