OVERVIEW: In recent years, as the structures of semiconductor devices have been successively scaled down in an extreme manner, such devices have become more multi-layered and 3D. Consequently, as conventional measurement methods are becoming impossible to use, the difficulty of simple interpretation is becoming a major problem in defect inspection. As regards wafer-surface unevenness, cross-sec...

D aily self-inspection of feet for sores and irritations is an essential and cost-effective diabetes self-management practice to prevent foot complications (1,2). It is relatively easy to perform and does not require equipment or supplies, yet nearly 40% of people with diabetes in New York state do not practice daily foot inspection, and Hispanics are the least likely to do so (3). Puerto Rican...

Many utility systems in the world have power plants operating with fossil fuel. In the thermal power plants maximum requirements of fuel is a coal. The handling of this fuel is a great job. To handle the fuel, i.e., coal, each power station is equipped with a coal handling plant. Maintenance of Critical Equipments for Coal Handling Plants (CHP) of Thermal Power Stations is typical job. The fail...

High Temperature Hydrogen Attack (HTHA) is a damage mechanism with a significant impact in the refinery industry, internationally. The mechanism results in gradual and relatively slow degradation of the vessel material during the incubation time period, but more rapid degradation thereafter. The paper gives an overview of this damage mechanism in the context of inspection surveys to identify de...

In today’s environment of shrinking resources, and consistent need for accurate inspections, simulation software is an effective cost cutting tool. CIVA is an advanced NDT simulation software dedicated to modeling ultrasonic (UT), radiographic (RT) and eddy current (ET) inspections without the need for physical test sample or inspection equipment. Each inspection module is comprised of simulati...

In the majority of semiconductor manufacturing, the visual inspection process of the wafer surface depends on human experts. However, the inefficiencies of human visual inspection has led to the development of image process to perform inspection tasks. The occurrence of different type of defect arises from the manufacturing processed variations, like miss-out calibration or poor maintenance of ...

This paper proposes a layered container inspection system for detecting illicit nuclear materials using radiography information. We argue that the current inspection system, relying heavily on the Automated Targeting System (ATS) and passive radiation detectors, is inherently incapable of reliably detecting shielded radioactive materials, especially highly enriched uranium (HEU). This motivates...

Phase monitoring is a technique which can be used in several aspects of automated manu-facturing: inspection, assembly and positioning. In phase monitored inspection, acoustic wavesreflected off a master part «re picked up by an array of microphones. The phase shift of the re-flected wave in each aiicrophone is compared to the subsequently measured values of a part to beinspecte...

BACKGROUND There is evidence from 2 previous meta-analyses that interventions to promote poison prevention behaviours are effective in increasing a range of poison prevention practices in households with children. The published meta-analyses compared any intervention against a "usual care or no intervention" which potentially limits the usefulness of the analysis to decision makers. We aim to u...

In meteorological and electric power Internet of Things scenarios, in order to extend the service life relevant facilities reduce cost emergency repair, intelligent inspection swarm is introduced cooperate with monitoring tasks, which collect process current scene data through a variety sensors cameras, complete tasks such as handling fault inspection. Due limitation computing resources battery...
