Abstract: Provided are a multi-function device for intensive shrimp farming and intensive shrimp farming systems using this device. The system comprises: shrimp ponds (100) with brackish water pumped from rivers or seas then treated with chemicals, sedimentation and micro-organisms; at least one multifunction device (200) to generate water flow, dissolve molecular oxygen, deliver and dispense shrimp feed and provide solution containing minerals, micro-organisms and other additives; pure oxygen supply device (300) capable of generating oxygen from the air to supply oxygen with purity higher than 90% to water in intensive culture pond to achieve consistently higher concentrations of dissolved oxygen saturated dissolved oxygen concentration; a network of porous sheets floats on the water to reduce the diffusion of oxygen molecules from the water to the air; and a network of lights for providing artificial light to change the feeding cycle of shrimp with industrial and natural food.

Abstract: A method of matching identification data comprising: acquisition of a data record comprising a plurality of fields; selection of matched records stored in a database, the data records having fields of type corresponding to the fields of the record acquired, the selection comprising for each record of the database: comparison of at least one field with the corresponding field of the record acquired, the comparison defining a discrete metric with at least three states of which a first state corresponds to an identity; and search for the match by traversal of a finite automaton in which each transition corresponds to at least one state of the comparison metric for at least one field, the finite automaton having at least two final states: matched and unmatched.
