Often inspection and maintenance work involve a large number of highly dangerous manual operations, especially within industrial fields such as shipbuilding and construction. This paper deals with the autonomous climbing robot which uses the "caterpillar" concept to climb in a complex 3D metallic-based structures. During its motion the robot generates in real-time the path and grasp planning in...

The inspection planning in electric power industry is used to assess the safety and reliability of system components and to increase the ability of failure situation identi®cation before it actually occurs. It re¯ects the implications of the available information on the operational and maintenance history of the system. The output is a ranked list of components, with the most critical ones at t...

The main aim of this paper is to present more accurate stochastic fatigue models for solving the fatigue reliability problems, which are attractively simple and easy to apply in practice for situations where it is difficult to quantify the costs associated with inspections and undetected cracks. From an engineering standpoint the fatigue life of a structure consists of two periods: (i) crack in...

background: effective clinical training is a fundamental ad important sector in medical education. studying the opinions of students in this era as a training core can be an effective step in devising clinical training as well as effective and efficient assessment. present study is conducted to determine the insights of medical trainees and interns on effective clinical training. methods: in th...

Lilies (Localisation and InterLeaving stragIES) was developed to deal with a forest fire fighting planning environment. The apphcation required adaptive planning in a reactive and generative environment. To model the application, it was necessary for multiple agents to be developed which added the usual communication [15, 19] issues. The planning environment needed to deal with both reactive an...

Recently the industries provide visual inspection processes in the plants for keeping and guaranteeing product quality. Many visual inspection processes are normally operated by the manual visual inspection. The results of the manual visual inspection are often unstable because the results are depended on the inspection worker skill. Currently the automated visual inspection technologies are ge...

In this paper, we present the first version of the MetroWeb tool designed to manage usability knowledge and to exploit this knowledge throughout evaluation process phases. The tool supports usability knowledge manipulation in general and specifically supports heuristic inspection. The usability evaluation process supported by the tool is decomposed into 4 main phases: planning, assessment, fina...

Automatically planning a camera viewpoint for tasks such as inspection in an active robot work-cell is a disJicult problem. This paper discusses new methods for computing viewpoints which meet the feature detectability constraints of focus, jield-of view, visibility, and resolution. A theoretical outline of the method is presented, followed by experimental results and a discussion offuture work,

Xiaoping Qian Kevin G. Harding, MEMBER SPIE General Electric Company Global Research Center Inspection and Manufacturing Technologies Schenectady, New York 12301 E-mail: [email protected] Abstract. Optical metrology has been widely used in quality inspection. However, the sensor setup during part inspection is often done in an ad hoc way. This leads to unnecessarily high signal dynamic range.
