摘要:
A natural gas pumping system that includes a reciprocating compressor having at least two cylinders, a first conduit in fluid communication with an outlet of the first cylinder, a second conduit in fluid communication with an outlet of the second cylinder, and a junction in fluid communication with the first conduit and the second conduit.
摘要:
A system, apparatus, and method for attenuating pulsations in a pumping system. The apparatus includes two pipe loops in fluid communication with a pump. Each of the pipe loops includes two branches with the first branch being longer than the second branch by an amount equal to half of a primary wavelength within a range of wavelengths propagating in a fluid discharged from the pump.
摘要:
An apparatus, system, and method for optimization. The apparatus, system, and method include a mechanism for ending an optimization when all models within one design tolerance of an optimum model have been simulated.
摘要:
A system, an apparatus, and a method for starting an engine. The system, apparatus, and method include determining a first quantity of fuel based on engine temperature, providing the first quantity of fuel to the engine during a first cycle of the engine, determining a second quantity of fuel based on engine temperature, providing the second quantity of fuel to the engine subsequently, and transitioning to an alternative fueling strategy.
摘要:
A signal modifying device, user interface, and method of modifying a signal. The signal modifying device includes a processor, a first input coupled to the processor and an output coupled to the processor. Instructions are stored within the processor that, when executed by the processor, cause the processor to provide a signal incident at the output that corresponds to a signal incident at the input.

摘要:
An expert system having a data storage device and a processor. The data storage device stores models having attributes, objectives having rules for evaluating the models, and strategies having rules for modifying the attributes. The processor evaluates a selected model in accordance with a selected objective and having the variable attribute set in accordance with a selected strategy to determine a characteristic value associated with the selected model and the variable attribute setting. The processor also stores information associated with improved results in the data storage device.
