High-density polyethylene (HDPE) pipes find versatile applicability for transportation of water, sewage and slurry from one place to another. Hence, these pipes undergo tremendous pressure by the fluid carried. The present work entails the optimization of the withstanding pressure of the HDPE pipes using Taguchi technique. The traditional heuristic methodology stresses on a trial and error appr...

The two-phase frictional pressure drop has a dominant effect in many industrial applications associated with the multiphase flow. This study investigated accuracy of several available methods for predicting different pipe diameters using 4124 experimental data points. It is observed that performance existing poor wide range operating conditions. Then, Artificial Neural Network models were propo...

subsea structures such as manifolds, line pipes and flow lines are important investments. also because of the sensitivity of environmental issues, corrosion of these structures is of vital importance. subsea corrosion management is different from on-shore and shallow water off-shore corrosion management in mainly three factors: materials, corrosion management practice and cathodic protection. t...

 Evaluate the impact on pipe performance and life expectancy of the transition (1991) from wall thickness class to pressure class designations in the manufacture and design standards for ductile iron pipes.  Study and compare historical failure rates of ductile iron pipes in a geographically diverse group of water utilities from North America and Australia.  Evaluate reliability and capabili...

Metallic miniature products have been highlighted as mini-/micro-structural components working as a precise mechanism, in dispensing systems, and in medical operations. In particular, the essential mechanical parts such as pipes and nozzles have strength and hardness sufficient for ejecting viscous liquids, solders, and particles. A low-temperature plasma nitriding process was proposed as a sur...

A pipeline is a popular architecture which connects computational components (filters) through connectors (pipes) so that computations are performed in a stream like fashion. The data are transported through the pipes between filters, gradually transforming inputs to outputs. This kind of stream processing has been made popular through UNIX pipes that serially connect independent components for...

Yahoo! Pipes is a well-known, widely used visual programming environment for creating data mashups by aggregating, manipulating, and publishing web feeds. It provides a natural laboratory for observing a range of end-user programming (EUP) behaviors on a large scale. We have examined more than 30,000 Pipes compositions in a search for regularities that might inform the design of EUP systems and...

The Pipes-and-Filters design pattern is a well-known pattern to organize and execute components with sequential dependencies. The pattern is therefore often used to perform several tasks consecutively on large data streams, e.g., during image processing or dynamic analyses. In contrast to the pattern’s familiarity and application, almost each common programming language lacks of flexible, featu...
