A system and method for predicting failures of rod pumps using a scaled load ratio is configured to: optimize the size of a rolling window, the upper and lower bounds of the normal range of the scaled load ratio, an alert period, and an alert frequency ratio; receive data of a current maximum/minimum loads on a surface rod, and a current speed; remove outliers showing an abnormality; scale the current maximum/minimum loads on the surface rod using the maximum/minimum loads on the surface rod in normal operation; calculate a scaled load ratio; calculate the average of scaled load ratios in the rolling window; determine whether the average of scaled load ratios is in the normal range, and classify the values as normal and abnormal events; calculate the ratio of the abnormal events in the alert period, and generate an alert when the calculated ratio exceeds the alert frequency ratio; and monitor a pump state using the pump failure prediction system.

A specification of programmatic instructions is received. The specification uses instances of functional components connected together using specified links and includes the programmatic instructions for controlling a motorized base device. A simulation and debugging environment for the specification is provided and a distributable version based on the specification is generated. The distributable version is provided to a remote wireless device that executes the distributable version of the specification including by providing commands to the motorized base device based on the distributable version of the specification.

An autonomous robotic system using an adaptive, interactive, and cognitive reasoner utilizing an advanced memory graph structure receives a natural language input. The natural language input is processed to identify components. At least a portion of the components of the natural language input is stored in a short-term artificial intelligence memory graph data structure. A long-term artificial intelligence memory graph data structure includes data that was previously stored in the short-term artificial intelligence memory graph data structure but is no longer stored in the short-term artificial intelligence memory graph data structure.

A vapor-liquid separator includes a casing having an accommodation space, an inlet at the casing to allow a refrigerant mixture fluid to be intaken to the accommodation space therethrough, and an outlet at the side of the inlet to allow a gas phase refrigerant separated from the refrigerant mixture fluid to be discharged therethrough.
