An automated algorithm is presented for the analysis and classification of eddy current bobbin probe data obtained from nuclear power plant steam generator tubes (SGT). This algorithm attempts to find a balance between the two seemingly conflicting requirements of SGT eddy current data analysis, namely, detecting and identifying as many of the actual defects as possible, whilst limiting the num...

In this paper, we study a class of graph drawings that arise from bobbin lace patterns. The drawings are periodic and require a combinatorial embedding with specific properties which we outline and demonstrate can be verified in linear time. In addition, a lace graph drawing has a topological requirement: it contains a set of non-contractible directed cycles which must be homotopic to (1, 0), t...

The proposed paper presents optoelectronic sensors for detection of a lack of thread in two types of textile machines. Possible reasons for this failure may be thread breaks or running out of material in the supply bobbin. The application of this method results in a rapid and timely stop of the workflow and reduces the time for restoring the operation of machines. This leads to an increase in l...
