Detection of defective products using stereovision

2019 Signal Processing: Algorithms, Architectures, Arrangements, and Applications (SPA), 2019
In this paper a stereovision detector of defective products for vision inspection on the production line is proposed. The proposed stereoscopic classifier uses an artificial neural network (ANN) to classify products by analysis of images taken from both the left and right view.

Production of Experimental Atrial Septal Defects

Vascular Surgery, 1976
Atrial septal defects (ASDs) were successfully created by punch biopsy technique in 67 dogs. The technique is simple, effective and provides an ideal model for the study of ASDs, either for testing closure devices or physiological experiments. The position and size of the defects may be varied according to preference. Of 45 animals subjected to cardiac

The transformation of defects in continuous-cast semifinished products into surface defects on rolled products

Metallurgist, 2006
The rolling of steel transforms certain defects formed during the steelmaking operation into other, outwardly similar defects (such as blowholes, longitudinal cracks, and folds). Like steelmaking defects, the defects formed during rolling cannot always be unambiguously evaluated by visual inspection and distinguished from the flaws formed during ...

Defect evolution in a product line environment

Journal of Systems and Software, 2004
One mechanism used for monitoring the development of the Space Shuttle flight control software, in order to minimize any risks to the missions, is the independent verification and validation (IV&V) process. Using data provided by both the Shuttle software developer and the IV&V contractor, in this paper we describe the overall IV&V process as used on ...

Defect Production in Semiconductors

1975
The different stages which govern the defect production are briefly described. Emphasis is placed on particular problems encountered in ion implantation such as the nature of the damage in highly disordered regions and the influence of the ionization on the damage production.

Keyhole Defect Production in Tubular Bone

Journal of Forensic Sciences, 2000
Abstract Fracture characteristics, reported primarily for the cranium, are valuable indicators of bullet direction. A bullet striking the vault tangentially produces an irregular opening, termed a “keyhole defect,” with the circular portion of the defect being the initial point of impact.

The impact of product development on the lifecycle of defects

Proceedings of the 2008 workshop on Defects in large software systems, 2008
This paper investigates the defects of a large embedded software development project over a period of about two years. It describes how software development and product development are organized in parallel branches. By mapping the defects reported on product development branches to the releases on the main line of software development, the paper shows

Removal of Defective Products Using Robots

2015
This paper addresses the utility of intelligent autonomous robotic arm for automatic removal of defective products in an industry. The task can be performed in two steps, finding the defective product with digital image processing and removal of defective part from the products. The image is regularly obtained and compared with the standard image.

Regulatory oversight of ENDS product defects

Tobacco Control, 2016
This commentary discusses regulatory options for addressing electronic nicotine delivery systems (ENDS)-related overheating, fire or explosion events in the USA. Currently, ENDS fall into a regulatory void, leaving customers unprotected from shoddy manufacturing and malfunctioning batteries.
