This paper presents the architecture used to develop a micro-robot for narrow pipes inspection. Both the electromechanical design and the control scheme will be described. In pipe environments it is very useful to have a method to retrieve information of the state of the inside part of the pipes in order to detect damages, breaks and holes. Due to the different types of pipes that exists, a mod...

We present HST NIC2 morphologies of a spectroscopic sample of massive galaxies at z ∼ 2.3, by extending our sample of nine compact quiescent galaxies (re ∼ 0.9 kpc) with ten massive emissionline galaxies. The emission-line galaxies are classified by the nature of their ionized emission; there are six star-forming galaxies and four galaxies hosting an active galactic nucleus (AGN). The starformi...

 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...
