This paper presents the bridge cable inspection robot developed in Korea. Two types of the cable inspection robots were developed for cable-suspension bridges and cable-stayed bridge. The design of the robot system and performance of the NDT techniques associated with the cable inspection robot are discussed. A review on recent advances in emerging robot-based inspection technologies for bridge...

The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap items are possible, these assumptions will underestimate the actual required quantity. The objective of th...

Background: Some animal infectious diseases such as tuberculosis, hydatidosis, and fascioliasis cause public health concerns and also significant economic losses. The goal of this study was to assess the rate of fascioliasis, hydatidosis, and tuberculosis in domestic animals during post-mortem inspection at Jijel slaughterhouse, North-Eastern Algeria. Methods: The present study was carried out...

General metrological inspection planning is among the least explored CAPP domains. This paper explores certain basic issues involved in inspection planning using case-based reasoning in an environment of a Generic CAPP Support System. Firstly, algorithmic methods for characterizing and extracting inspection features are proposed and discussed. A sequential knowledge based filtering method is de...

Humans and machines each have their own advantages and disadvantages in performing visual inspection tasks. In order to capitalize on the respective advantages and offset the disadvantages of humans and machines, hybrid inspection systems have been proposed. In response, research was conducted to evaluate three different inspection systems: a human inspection system and two hybrid inspection sy...

Recently, 100% inspection using automated systems has seen more frequent application than traditional sampling inspection using human inspectors. Nevertheless, humans still outperform machines in most attribute inspection tasks. Studies have shown that hybrid inspection systems where humans work corporately with machines might achieve superior system performance than either humans or machines a...
