In the article we deal with the issue of non-destructive diagnostics of a specified part on the railway, namely the rail. The chapters are devoted to the non-destructive defectoscopic method, or more precisely an ultrasonic test, which is performed by DIO 562 device and it also includes data processing from the measurement. The article briefly describes location and character of defects on the rails and actual process of measurement. The measurement was performed on a standard length of 10 km, with the use of a device capable of copying shape of the rails during the ultrasonic examination. The evaluation of the measurement was processed in specialized software DIO 2000 on the PC. Based on this evaluation, three manual inspections were implemented to determine the character of defects. The conclusion of this article is a precise determination of character and origin of these selected defects, and suggestion for their removal or replacement according to the valid regulations.

Abstract The opportunity of researching and defining flooded areas using digital landscape model, hydrological analysis through specialized software and data processing in the GIS, is being unveiled. Multiple methods of defining flooded areas on the basis of result processing of transverse profiles of a specific area of the Rositsa River near the city of Sevlievo, are developed.

ABSTRACTRutherford backscattering spectrometry (RBS) is used to characterize the stoichiometry of graphite intercalation compounds (GIC). Specific application is made to several stages of different donor and acceptor compounds and to commensurate and incommensurate intercalants. A deviation from the theoretical stoichiometry is measured for most of the compounds using this non-destructive method. Within experimental error, the RBS results agree with those obtained from analysis of the (00ℓ) x-ray diffractograms and weight uptake measurements on the same samples.

Abstract Organic solderability preservatives (OSPs) pad is one of the pad finishing technologies where Cu pad is coated with a thin film of an organic material to protect Cu from oxidation during storage and many processes in IC manufacturing. Thickness of OSP film is a critical factor that we have to consider and control in order to achieve desirable joint strength. Until now, no non-destructive technique has been proposed to measure OSP thickness on substrate. This paper reports about the development of EDS technique for estimating OSP thickness, starting with determination of the EDS parameter followed by establishing the correlation between C/Cu ratio and OSP thickness and, finally, evaluating the accuracy of the EDS technique for OSP thickness measurement. EDS quantitative analysis was proved that it can be utilized for OSP thickness estimation.
