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...
For polishing the ultra-thin TMT M3MP, a polishing support system with 18 hydraulic supports (HS) is introduced. This work focuses on the designing and testing of these HSs. Firstly the design concept of HS system is discussed; then mechanical implementation of the HS structure is carried out, with special consideration of fluid cycling, work pressurization and the weight component. Afterward t...
Mathematical and programming toolkit of the computer aided design of the axonometric piping diagrams
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...
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...
