A novel way of measuring a portion of the pipe’s crosssection Þlled with liquid (PPCSFWL) and ßow-rate of liquid through partially Þlled pipes, based on electromagnetic method, is proposed. The technique developed is valid for laminar ßow and cylindric pipes. The measuring method, based on nonlinear relationships between the PPCSFWL and the measured signals, is developed and utilizes an optimal...

in the diesel engine exhaust gas recirculation (egr) components, valve and connecting pipes are the critical components and fails often during new engine development. these components are important for meeting nox emissions norms. therefore design of these components should remain robust. but the challenge in design is compact packaging of complete egr components on the engine consequently vibr...

Michel Foucault's analysis of Magritte's painting, Ceci N'est Pas Une Pipe, and the later work, Les Deux Mystéres, serves as a template, that is broadened to consider different representations of persons and patients. Kant's noumenal person is contrasted with phenomenal persons, and the well individual is contrasted with the patient. Patients may be considered as the subject or object of illnes...

The peer-to-peer (p2p) paradigm is attracting increasing attention from both the research community and software engineers, due to potential performance, reliability and scalability improvements. This paper emphasizes that JXTA can help teachers to teach p2p with Java. This paper also presents an approach for performance analysis of JXTA pipes one of the key abstractions in JXTA, which has not ...

High-temperature pressure pipelines are extensively used in petrochemical plant and power stations. Severe pits or wall loss defects can be internally produced after a certain period of time due to media corrosion and cavitation erosion. These defects finally lead to leakage of the pipes. In order to search for a good non-destructive method for these defects, a large pipe testing installation w...

1. ABSTRACT We are developing innovative heat pipes based on Nano-Structured Titania (NST) with a potential for high heat carrying capacity and high thermal conductivity. These heat pipes have a flat geometry as opposed to a cylindrical geometry found in conventional heat pipes. The flatness will enable a good contact with microprocessor chips and thus reduce the thermal contact resistance. We ...

The enormity of the problem of deteriorating pipeline infrastructure is widely apparent. Since a complete rebuilding of the piping system is not financially realistic, municipal and utility operators require the ability to monitor the condition of buried pipes. Thus, reliable pipeline assessment and management tools are necessary to develop long term cost effective maintenance, repair, and reha...

Pulse radar systems, known as subsurface interface radars, have been widely used to locate underground objects. Three-dimensional towershaped antennas were developed to replace conventional plane antennas and accurately detect the location and depth of underground objects like gas pipes, water pipes and transmission cables. The newly developed radar system using these tower-shaped antennas is c...

Abstract: This paper proposes a magnetic actuator using multiple vibration components to perform locomotion in a complex pipe with a 25 mm inner diameter. Due to the desire to increase the turning moment in a T-junction pipe, two vibration components were attached off-center to an acrylic plate with an eccentricity of 2 mm. The experimental results show that the magnetic actuator was able to mo...

This paper presents a methodology to quantify and to locate leaks. The original contribution is the use of a tool based on the TrustRank algorithm for the selection of nodes for pressure monitoring. The results from these methodologies presented here are: (I) A sensitivity analysis of the number of pressure transducers on the quality of the final solution; (II) A reduction of the number of pipe...
