  • Publication number: 20240104394
    Abstract: Provided are computing systems, methods, and platforms that automatically produce production-ready machine learning models and deployment pipelines from minimal input information such as a raw training dataset. In particular, one example computing system can import a training dataset associated with a user. The computing system can execute an origination machine learning pipeline to perform a model architecture search that selects and trains a machine learning model for the training dataset. Execution of the origination machine learning pipeline can also result in generation of a deployment machine learning pipeline configured to enable deployment of the machine learning model (e.g., running the machine learning model to produce inferences and/or optionally other tasks such as re-training and/or re-tuning the model).

  • Patent number: 8728327
    Abstract: A method and apparatus are provided for the controlled application of ultrasonic energy for conditioning of mixtures of gas and liquids by evolving and/or agglomerating gas bubbles existing with or in a liquid or for coalescing droplets of liquid dispersed in another liquid. The invention in preferred embodiments thereof comprises a coalescing apparatus for increasing the droplet size of a mixture formed as a liquid dispersed in another liquid, and a de-gassing apparatus arranged to evolve and/or agglomerate gaseous bubbles in a gas/liquid mixture. In the apparatuses, ultrasonic transducers are used to impart vibrational energy to the mixtures.

  • Patent number: 6197095
    Abstract: A subsea multiphase fluid separation system and method are disclosed which provide for efficient and reliable remote separation operation at deep and ultra deep water depths including depths of ten thousand feet or more. The system is preferably of modular construction wherein the modules are secured in a single frame to be lowered as a unit to the seabed. The system utilizes reliable cyclonic operation. The sequence of process steps is designed to make the system more efficient as compared to surface separating systems and thereby permit a more compact size as is desirable for subsea operation. The method of operation includes up to five basic process steps with the initial step in one embodiment including cyclonically separating solids. In a presently preferred embodiment, the cyclonic solids separator is sized to eliminate solids greater than fifty microns. A second stage is directed to cyclonically removing bulk gas from the liquid in either a cyclone or auger separator.

  • Patent number: 5498346
    Abstract: An oil spill recovery system includes a first hydrocyclone separator and optionally a second hydrocyclone separator located on a floating vessel floating on a body of water from which spilled oil is to be recovered. A recovered fluid containing oil and water emulsion and a large amount of free sea water is recovered from the body of water. The first hydrocyclone separator separates the recovered fluid into a first underflow stream containing oily water and a first overflow stream which contains substantially all of said oil and water emulsion. The oily water underflow stream from the first hydrocyclone separator is then directed to a second hydrocyclone separator which separates it into a second underflow stream which is returned to the sea as clean water, and a second overflow stream. The first overflow stream is stored in on-board ship's storage. The second overflow stream may be stored in ship's storage or recycled for further separation.

  • Patent number: 5302294
    Abstract: A hydrocyclone separator separates an oil and water stream into an underflow stream containing primarily water and an overflow stream containing a relatively higher oil concentration than the underflow stream. Quality control of both the underflow stream and the overflow stream is of concern, and typically a de-oiling separator is placed downstream on the underflow stream, and a dewatering separator is placed downstream on the overflow stream from the hydrocyclone separator. A degassing separator is also generally utilized upstream of the inlet to the hydrocyclone separator. Various monitoring and control systems are provided for controlling the split ratio of the underflow and overflow streams of the hydrocyclone separator.
