The Mahalanobis-Taguchi System is a diagnosis and forecasting method for multivariate data. Mahalanobis distance is a measure based on correlations between the variables and different patterns that can be identified and analyzed with respect to a base or reference group. This paper presents a comparison of the Mahalanobis-Taguchi System and a standard statistical technique for defect detection ...

In this paper, we study the problem of delay defect diagnosis based on statistical timing models. We propose a diagnosis algorithm that can effectively utilize statistical timing information based upon single defect assumption. We evaluate its performance and its applicability to single as well as multiple defect scenarios via statistical defect injection and simulation. With a statistical timi...

This paper is part of a larger study of remote print defect diagnosis. The goals of the integrated print defect diagnosis system are to reduce diagnosis time, streamline communication between customers and call center personnel, increase print defect handling efficiency and boost customer satisfaction through improved service. In this paper, we aggregate the information stemming from two diagno...

Logic defect diagnosis is to locate the defect spots in a digital IC that fails testing. It is one of the critical steps during the process of manufacturing yield improvement. Automatic defect diagnosis techniques for circuits with single defect have been improved significantly. However, the techniques for multiple defect diagnosis are still inadequate. In this paper, we propose an effective he...

parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

Opportunities exist for developing the Acoustic Emission (AE) technique on various forms of rotating machinery, such as gearboxes. This paper provides a short summary on recent developments in the application of AE to gear defect diagnosis, and, experimental results are presented that examine and explore the effectiveness of AE for seeded gear defect diagnosis. It is concluded that the applicat...

In this paper, three types of (philosophical, optimistic and pessimistic) multigranulation single valued neutrosophic (SVN) covering-based rough set models are presented, and these three models are applied to the problem of multi-criteria group decision making (MCGDM).Firstly, a type of SVN covering-based rough set model is proposed.Based on this rough set model, three types of mult...
