Abnormal Piping Vibrations of a Suction Piping System of a Reciprocating Pump.

Pressure pulsations in reciprocating pump piping systems Part 1: modelling

A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...

Automatic Piping System in Ship

One of the most complicated and time-consuming process in ship production is to determine the optimum route of piping. The automatic system to generate optimum collision free routes for pipes is presented in this paper. In the past, research has been primarily focused on the use of only deterministic or only nondeterministic optimization techniques to find the optimal route. In this paper, the ...

case that brought down South Korean stem cell researcher Hwang Woo Suk early this year”. The Los Angeles Times editorial page bemoaned that, “Science took an unnecessary leap forward Wednesday,” by attempting to find a technological fix to address political and religious objections to stem-cell research. “It’s an impressive advance, but scientists — and society — would be better off if they cou...
