This record of study was a sequential quan-QUAL mixed methods study that followed a case-selection explanatory sequential mixed methods research design to understand the employment mobility experiences of teachers on a ...

This research demonstrates that robots can achieve socially acceptable interactions, using loosely synchronized head gaze-speech, without understanding the semantics of the dialog. Prior approaches used tightly synchronized ...

As the pressure in older oil wells decrease over time, water injection services are becoming more prevalent on offshore platforms. Water injection is used to maintain the pressure in the wells and displace the oil from the ...

This paper deals with the design functions and case histories of gear couplings. A brief discussion of the various basic design features of gear couplings and their lubrication system is presented. This is followed by ...

Worldwide, current technology has opened a wide range of new applications for electric motors, many of which have traditionally employed mechanical (turbine) drivers. While the use of electric motors for these high speed ...

There are many approaches to the design of thrust and journal hearings for high speed turbomachinery, ranging from the simplest flat thrust bearings and plain journal hearings to the very sophisticated multiwedge designs ...

This paper is a discussion of the design, manufacture, test, and field operation of a totally oil-free string of rotating equipment. The turbomachinery string consists of a multistage centrifugal compressor driven by a ...

Historically, the high-speed centrifugal pump was developed prior to World War II for rocket engine fuel pump applications for its advantages of light weight, compactness and dry running capability. Industrial derivatives ...
