The IAEA continues to provide credible assurance to the international community regarding States’ adherences to their safeguards obligations under the nuclear NonProliferation Treaty. Generally, industrial activities, including those related to the nuclear fuel cycle, are operating on increasingly larger scales involving more equipment, more nuclear material products and flows. With limited res...

The digital band-pass filters used in the system and the DSP algorithm realizing the FM discriminator were designed using Matlab [3]. The filter coefficients and discriminator algorithm are incorporated in a program running on the DSP board. The DSP board samples the signal emitted by the ground-based radio navigation aid and processes the sampled data to obtain ILS and VOR information. The sam...

The work reported here is the development of a first prototype portable ultrasonic inspection instrument based on EMAT (electromagnetic acoustic transducer) technology. The goal was to demonstrate EMAT inspection capabilities for small-size flaws in metal parts and to build a self-contained NDE unit that had a high degree of signal processing on-board so that human interpretation was minimized....

The estimation of central venous pressure (CVP) by inspection of the neck veins is regarded as a quintessential example of effective bedside cardiovascular examination because it is virtually cost-free and requires minimal time and no equipment. In the upright position, venous drainage from the head occurs primarily through the vertebral veins, allowing the jugular vein to act as a manometer, “...

With the improvement of electric information, 3D visualization for the substation in the planning, designing, inspection, training and other aspects calls for a gradual increase. 3D rendering of the current technology is not yet mature, and equipment modelling is too complex, we propose a virtual 3D substation, which is an image-based system. The key issues include a spherebased methods of fish...

Magnetic flux leakage (MFL) measurement is one of the most widely used non-destructive testing techniques for in-service inspection of oil and gas pipelines. Three methods, Numerical computation, theory analytical and experiment, have been used to model the MFL testing and have been investigated separately before. In this article, we introduced a MFL analytical model based on dipole magnetic ch...

This article presents a Decision Support System which focuses on an important organizational context: maintenance decisions. Usually, a specific management system is required to deal with data on failure, reliability, maintainability and availability regarding equipment. The maintenance context is surrounded by uncertainty and does not provide a clear profit from its activities, and thus requir...

A bogie system is the key equipment of railway vehicles. Rigorous practical evaluation of bogies is still a challenge. Presently, there is overreliance on part-specific experiments in practice. In the present work, a risk evaluation index system of a bogie system has been established based on the inspection data and experts' evaluation. Then, considering quantitative and qualitative aspects, th...

BACKGROUND Slaughter reindeer are exposed to stress caused by gathering, handling, loading and unloading, and by conditions in vehicles during transport. These stress factors can lead to compromised welfare and trauma such as bruises or fractures, aspiration of rumen content, and abnormal odour in carcasses, and causing condemnations in meat inspection and lower meat quality. We investigated th...
