Abstract This paper sketches a grammar of English relative clause constructions (including infinitival and reduced relatives) based on the notions of construction type and type constraints. Generalizations about dependency relations and clausal functions are factored into distinct dimensions contributing constraints to specific construction types in a multiple inheritance type hierarchy. The gr...

Ultrasonic crack detection and sizing is an essential tool in determining the asset integrity of pressure vessels and piping. Conventional UT shear wave methods have proved to be time consuming, requiring high skill levels and frequently resulting in unreliable and inconsistent data. Phased array UT technology can provide novel solutions to these problems with reliable results, imaging of the c...

An ultrasonic guided wave system for pipe inspection is proposed. Using guided wave experience to date on a variety of different tubing problems, feasibility experiments have already been conducted on piping under insulation in both a laboratory and chemical processing facility field environment. Several guided wave techniques are introduced, one using a broad banded variable angle beam transdu...

The problem of finite amplitude wave propagation in fluid-filled distensible tubes, although of potentially wide general interest in industrial piping systems, finds particularly important application in biomedical circulatory phenomena. Mathematical and laboratory studies of such coupled fluid-shell interactions have led to novel contributions in the field of Biomechanics, an area of continuin...

Ferric oxide, hematite, "red rust" , it has a lot of names but there is no argument that it is undesirable. It is a loosely adhering oxide layer which has poor heat transfer capabilities. It also tends to deposit elsewhere in the system. It can deposit in the coil, in steam traps and piping downstream, and can eventually reach the boiler. In the boiler it can form further deposits, which in tur...

The flow and dispersion characteristics of the fire extinguishing agent in pipings concentration distribution nacelle are essential for optimizing aircraft system. In present work, we developed a three-dimensional CFD model to simulate transport piping nacelle. results show that length structure near nozzles affect concentration, pressure, rate, agent. smaller bend angle connection with main pi...

The spillway of the Swa earthen dam, constructed in Yedashe Township, Bago Region, Myanmar, collapsed suddenly on 29 August 2018 and resulted a huge flood to downstream areas causing fatalities displacement thousands localities. This study aimed assess breaching process terms parameters such as average breach width, failure time peak outflow, mechanisms. We analyzed event from changes site befo...

This study evaluated changes in delta-ferrite content depending on the preheating of AISI 316L stainless steel. We also determined reasons for variation content, which affects corrosion resistance. Changes after was confirmed using a Feritscope, and microstructure analyzed optical microscopy (OM). found that size decreased when time increased at 1295 oC, could be controlled through preheating. ...
