Abstract: This paper discusses the requirements for high-speed centrifugal compressor drive couplings and some of the problems created by conventional couplings. It describes two new coupling designs and ...

Abstract: Cardan motion has been treated in the literature principally in terms of infinitesimally separated positions. Here Cardan motion is synthesized for all combinations of up to five infinitesimally ...

Abstract: The scales formed on seven ferritic and ten austenitic types of commercial tubing presently in use and of potential future use for superheater service were examined after 6, 12, and 18 months’ ...

Abstract: In multi-actuator powered control applications, load coupling can cause severe interactions between the actuators. It is possible to reduce such interactions by incorporating suitable controller ...

Abstract: This study determined whether termiticides (insecticides that are formulated and applied for termite control), applied according to label directions to the soil surrounding basement walls, can leach into foundation drainpipes. ...

Abstract: Human vascular systems have considerable anatomic variations. In diseased situation, significant pathological changes will be developed with the systems. However, vascular catheterization devices ...

Abstract: Foundation drains have long been utilized for reducing uplift pressures under masonary dams. It has also been widely assumed that when tension develops at the heel of a dam, that full headwater pressure extends for the ...
