Worldwide, millions of kilometres sewers are constructed from concrete pipes. Unfortunately, susceptible to corrosion biogenic hydrogen sulphide, and, though they may pass visual inspection, their ability hold together under load be degraded. This paper presents the design a teleoperated robot with protractible probe, that allows an operator apply localised selected points within sewer pipe. We...

In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, and produce an RDF output which is itself accessible via a stable URL. Humans can also use pipes directly thanks to HTML wrapping of the pipe parameters and outputs. The implem...

Problem. The use of road culverts is currently an effective and relatively cheap means passing surface water under the body embankment. number pipes on highways in areas with different topography approximately 1.4 per 1 km route. Road pipes, depending cross section, can be round, rectangular, oval, elliptical, arched, polycentric. following are mainly used roads: round - 87%, rectangular 9%, re...

In the application of guided waves NDT, the selection of exciting frequency is not only related with the setup of sensor, but also with the characteristics of pipe’s structure and material. In this paper, the characteristic of guided waves propagation in pipes that L(0,1) and L(0,2) have a cutoff frequency are respectively discussed, and the calculation formulas of their cutoff frequency are gi...

Natural pipes are common in many upland blanket peats, yet little is known about pipe network morphology or pipeflow processes. Most information on soil piping comes from the shallow peaty podzols of the Welsh uplands, where monitoring suggests that pipes may be important contributors to streamflow. This paper presents information on piping and pipeflow from a deep upland blanket peat catchment...

Integrating heat exchanger pipes with structural foundations in one system has created a new renewable solution for buildings’ thermal loads. However, the interaction between and geotechnical loads makes their design more complex challenging. This review-study represents current state of knowledge about thermo-mechanical behaviors energy piles. It also investigates key parameters that affect co...

In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...

BACKGROUND Concurrent use of tobacco products such as cigarettes and water pipes may be associated with increased risk of nicotine dependence and smoking-related complications. Accurate statistics are not available regarding the prevalence of water pipe use or concurrent use of cigarettes and water pipe in the Iranian population. Thus, this study sought to assess the prevalence of concurrent us...
