Autonomous vehicles will not be driven by a human being. The missing of the human being will make the vehicles less inspected because a human being often listens to the engine and its sounds. A passenger in an autonomous vehicle usually does other things and even sleeps, so the human inspection on the engine and on the pipes system will not be effective. This paper suggests a system that alerts...

First discharge calculations are carried out to set release characteristics for the hazardous chemical (including depressurisation to ambient). Scenarios which may be modelled includes releases from vessels (leaks or catastrophic ruptures), short pipes or long pipes and releases of combustion products following a warehouse fire. Released considered include releases of sub-cooled liquid, superhe...

A finite-difference procedure is employed to predict the development of turbulent flow in curved pipes. The turbulence model used involves the solution of two differential equations, one for the kinetic energy of the turbulence and the other for its dissipation rate. The predicted total-velocity contours for the developing flow in a 180’ bend are compared with the experimental data. Predictions...

A numerical model of the evaporating liquid meniscus under saturated vapor conditions in wick microstructures has been developed. Four different wick geometries representing the common wicks used in heat pipes, viz., wire mesh, rectangular grooves, sintered wicks and vertical microwires, are modeled and compared for evaporative performance. The solid-liquid combination considered is copper-wate...

Alias Limited, market leader for piping isometric software, today announced the availability of I-View, a 3D pipe visualization tool. I-View is capable of handling single or multiple pipes from any 3D plant design system supporting ISOGEN. Even piping ® les from diå erent systems can be viewed as a single model. This new module now provides I-Sketch users with the ability to view pipes in true ...

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...

This paper provides new insights into the problem of selecting filter center frequencies for the auditory filterbanks. We propose to use a constant frequency distance and a consistent frequency coverage as the two metrics that motivate the logarithmic frequency scaling and a regularized selection of center frequencies. The frequency scaling and the consistent frequency coverage have been derive...

Abstract In refrigeration systems, evaporative condensers have two main advantages compared to other condensation heat exchangers: They operate at lower temperature than traditional air-cooled and require a quantity of water pumping power towers. The mass transfer that occur on tube batteries are difficult study. aim this work is apply an experimental approach investigate the performance conden...

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...
