Methane is one of the most significant anthropogenic greenhouse gases, whose global warming potential and sources are well documented. The natural gas industry is a major source of methane emissions. In 2001, unintended (fugitive) leaks from valves, piping connectors, open-ended lines, and pump and compressor seals totaled 3.9 Tg (58% of total U.S. emissions from the natural gas industry). In t...

A lot of plumbings exist in factories and so on. It is difficult for humans to inspect them directly. Therefore, automated inspection by robots is desirable. However, many of existing inspection robots have to rotate the camera because a conventional camera can see only one direction while a piping has a cylindrical geometry. The use of an omni-directional camera is effective for the solution o...

The role of lysosomes in important cellular responses, including phagocytosis, cell surface repair, and autophagy underlies a number of human diseases. Furthermore, the role of the lysosomal surface in TORC1 signalling has revealed unexpected properties of these organelles. In this issue, Sridhar et al (2013) uncover an important role for PI(4)P for lysosome function under normal nutrient condi...

With the aim of tracking the deteriorating process of a specific individual multi-state system consisting of more than one multi-state component, a dynamic reliability assessment method which can utilize systemlevel observation history to dynamically update the reliability function of multi-state degraded systems is developed in this paper. The current and future state probabilities of componen...

Several papers deal with the problem of managing low conductivity water plant in accelerators [1,2], but outside of this field, only electric power generation plants (cooling of high voltage stator windings) seems to suffer from similar troubles. During eight years operation of the DA NE water cooling system some critical situations have been successfully managed by upgrading the demineralized ...

The problem of the automation of the designing of the axonometric piping diagrams include, as the minimum, manipulations with the flat schemas of three-dimensional wireframe objects (with dimension of 2,5). The specialized model, methodical and mathematical approaches are required because of large bulk of calculuss. Coordinate systems, data types, common principles of realization of operation w...

The paper discusses the use of geometric constraints in a CAD model-based photogrammetric system. The CAD models are represented by CSG (Constructive Solid Geometry) models. The geometric primitives that make up the CSG model are parameterized by their pose and shape parameters. Geometric relations, or constraints, between these primitives are expressed using these parameters. Constraints can b...

in this paper we investigate the mechanism of internal erosion caused in the right abutment of the shahghasem dam’s spillway. shahghasem dam is an earthen dam located in yasouj, in southwest of iran. a significant hole and pipe have been observed in the corner of the right abutment from upstream view. the foundation is marlstone, which has low cohesion and susceptible for internal erosion and p...

The asbestos remediation for wrap-andcut piping in D&D applications for DoE is conservatively estimated at $300 million complex-wide. The development of an automated system to separate the insulation from the pipe, allowing for waste-volume reduction and wastesegregation is offered as a solution capable of saving DoE between 20% and 40% of the total job cost in years to come. The application to...
