Defect engineering using self-doping or creating vacancies in polycrystalline oxide based materials has profound influence on optical absorption, UV photo detection, and electrical switching. However, defects induced semiconducting devices show enhancement detection photosensitivity, hence still remain interesting the field of optoelectronics. In this study, defect is discussed along with their...

VLSI Design Laboratory, a Applied Electronics Laboratory Department of Electrical and Computer Engineering University of Patras, Rio 26500, Greece ABSTRACT In this paper a pilot system for defect detection and classification of web textile fabric in real-time is presented. The general hardware and software platform, developed for solving this problem, is presented while a powerful novel method ...

Recent computational methods of wafer defect detection often inspect Scanning Electron Microscope (SEM) images of the wafer. In this paper, we propose a kernel-based approach to multichannel defect detection, which relies on simultaneous acquisition of three different images for each sample in an SEM tool. The reconstruction of a source patch from reference patches in the three channels is cons...

patients and methods previously recorded data of 231 patients who underwent surgical closure of vsd between january 2009 and january 2012 at the rajaie cardiovascular medical and research center were retrospectively reviewed. vsd surgical repair was performed using continues suturing technique in group a patients (n = 163, 70.6%) and interrupted suturing technique in group b patients (n = 68, 2...

Abstract Sewer systems play a key role in cities to ensure public assets and safety. Timely detection of defects can effectively alleviate system deterioration. Conventional manual inspection is labor-intensive, error-prone expensive. Object powerful deep learning technique that complement and/or replace conventional inspection, especially complex environments. This study compares two classic o...

This article helps define questions regarding defect detection techniques and presents a survey of empirical studies on testing and inspection techniques. We then interpret the findings in terms of practical use. The term defect always relates to one or more underlying faults in an artifact such as code. In the context of this article, defects map to single faults. Thus, we use the terms defect...

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...

Abstract* Introduction: Visual system have been considered as among important sensory system in animals’ life span and their survival is closely related to normal visual system functioning. Since in previous studies it have been revealed that morphine consumption during pregnancy could lead to defect and delay in nervous system development in the embryos, in the present study, changes induc...
