After 1994, highway bridges are maintained under the Special Law on Structure Safety in Korea. To keep a structure good condition, inspection of the structure has to be performed periodically. The inspection is hard work and needs a lot of time and many inspectors to inspect the structure that is important or damaged. Generally, This contains subjectivity of inspector, and so the result of insp...

A distributed vision network is proposed to tackle industrial packaging inspection. The system consists of independent networked inspection stations able to address efficiently parallel inspection tasks such as product identification, character verification, tag inspection and content & packaging quality control at a high production speed. Existing and innovative inspection algorithms such as s...

In this paper, the concept of cumulative count of conforming chart (CCC chart) is applied in inspection and maintenance planning for systems where minor inspection, major inspection, minor maintenance and major maintenance are available. Several inspection and maintenance plans are defined and studied quantitatively. Analytic expressions of relevant statistics and their expectations are derived...

To prevent members in steel bridges from fatigue failure, one usually needs to perform frequent periodic bridge inspections and employ detailed inspection methods. This is especially true for fracture-critical members or details. Carrying out these inspections puts a large burden on a transportation agency’s bridge maintenance budget. A systematic reliability-based method for inspection schedul...

With the growth of the national economy, there is increasing demand for electricity, which forces transmission line corridors to become structurally complicated and extend to complex environments (e.g., mountains, forests). It is a great challenge to inspect transmission line in these regions. To address these difficulties, a novel method of autonomous inspection for transmission line is propos...

In-pipe robots, which have a long history of development in robotics, can be.This paper describes a mobile feeder pipe inspection robot that can minimize the irradiation dose to human workers by automating the measurement process.Recently, many pipe inspection robot systems have been developed. Initially, development ...

PURPOSE The article summarises the process and the results of the first, integrated inspection of managed care services for people with learning disabilities in Scotland. The multi-agency model used was developed to be congruent with the existing performance inspection models, used by single agency inspection. The inspection activities and main outcomes are described, and suggestions are made f...

In the first half of the article, inspection organization and programs are briefly dealt with. This is followed by a more detailed review of inspection, detection and monitoring methods, which comprises visual inspection, radiography, ultrasonic testing, eddy current technique, magnetic particle inspection, the use of liquid penetrant, the electric field signature method, acoustic emission, lea...

In this paper we use the value chain concept, which links the level of value of the final product to the fitness of working products, for planning inspection activities. Following this value chain an inspection tackles the risk of a lower level of value due to defects in a working product from two sides: Inspection lowers the frequency of loss with removal of defects and the size of potential l...

This paper describes the basic actions proposed for quality inspection. These actions involve structuring a Decision Supporting Expert System (DSES) to help with those decisions related to the preliminary activities for inspection development—most of them relating to determining of the need or convenience of carrying out the inspection itself. Once the opportunity to carry it out is defined, th...
