Abstract: A computer implemented method of matching ontologies is disclosed. The method includes, for each pair of entities of a first ontology and a second ontology, wherein each pair of entities includes a first entity from a first plurality of entities of the first ontology and a second entity from a second plurality of entities of the second ontology, and wherein the first entity and the second entity of each pair of entities is of a same data type: (1) determining a vector of similarities for the pair of entities; (2) determining a confidence score for the vector of similarities; (3) determining a relation score for each relation type based on the vector of similarities to measure relatedness between the first entity of the pair of entities and the second entity of the pair of entities; and (4) generating a mapping ontology based on the relation type, the relation score, and the confidence score of each pair of entities.

Abstract: A method for predicting a failure of oilfield equipment based on univariate time series includes providing training data by a sensor. A training data stream comprising the training data is received by a preprocessor. The method further includes extracting training data segments and identifying each training data segment of the training data segments as corresponding to a normal operational state of the first oilfield equipment or a failed state of the first oilfield equipment. The method also includes generating a shapelet-based decision tree and receiving a test data stream from a sensor of second oilfield equipment. The method further includes determining, based on the shapelet-based decision tree, whether one or more test data segments extracted from the test data stream predict a failure of the second oilfield equipment.

Abstract: Hazardous waste is treated by shredding and then passing the material through an enclosure by means of a conveyor through direct steam impingement. The enclosure is maintained at a pressure greater than or equal to atmospheric pressure in order to maintain steam temperature at or above 212° F. Pressure locks are positioned at an inlet and discharge of the enclosure. The pressure locks allow transport of waste material into and out of the enclosure while maintaining a pressure differential between the interior and exterior of the enclosure.

Abstract: Systems and methods of managing a workflow of an oilfield activity are provided. A problem in the oilfield activity is identified, where the oilfield activity includes a number of tasks necessary to complete a project of a number of projects in the workflow, and where the number of tasks are arranged within a number of workflow states associated with the oilfield activity. A sequence for the number of tasks is selectively updated based on an analysis of the oilfield activity performed by a user. The project is analyzed by examining a progress of the project within one of the number of workflow states to obtain a decision, where the project is associated with the problem. The problem is resolved in the oilfield activity based on the decision.

Abstract: Containerized medical waste is treated by shredding, and then passing the shredded material, by means of a screw conveyor, through a direct steam impingement stage and a dehydration stage in which the material is brought into contact with a hot surface to vaporize moisture and thereafter passed through a low pressure chamber in which the vapor is drawn off.

Abstract: Containerized medical waste is treated by a process in which the materials are carried by a conveyor under a negative pressure to a multiple-stage shredder. Sodium hypochlorite is added at several points in the shredder section of the apparatus. The output of the shredder is compressed and the liquid component which is separated out is recirculated. The compressed solid is conveyed through a conveyor in which the temperature is maintained at a level just under 212.degree. F. by the introduction of steam. The pressure is maintained at or below atmospheric pressure at all points in the system to prevent release of contaminated materials into the atmosphere. By using the combination of sodium hypochlorite and steam, it is possible to eliminate live microorganisms entirely while still taking advantage of low pressure to avoid accidental release of contaminated materials.

Abstract: A system for disposing of large amounts of infectious hospital waste includes a generally sealed enclosure containing an apparatus for delivery, disintegration, and decontamination of waste materials. A dual conveyor arrangement provides a positive delivery of large waste containers to be disposed to a disintegrator while preventing material from being thrown from the disintegrator. The disintegrator comprises two, large, counter-rotating hammermills capable of effectively disintegrating articles of substantial size. The system enclosure is maintained at a negative pressure and adapted to prevent escape of airborne contamination from the system. A variety of protective features is also incorporated into the system to clear the disintegrator in cases of overload, to avoid power surges upon system start-up, and to effect an orderly shutdown of the system.

Abstract: A system is provided having a generally sealed cabinet and separator. A blower is provided in the sealed cabinet to provide a negative pressure within the cabinet. A waste entrance is provided in the cabinet which provides a sealed, rotatable input for the introduction of hospital waste to the system. In the system, the input rotates upon operation of a switch to direct solid waste to a disintegrator, such as a hammermill, wiht a flow of disinfectant fluid. Upon disintegration, the waste particles and disinfectant fluid are carried to the separator which is sealed with the cabinet. The solid waste is separated from the decontaminant fluid which is then directed to a public sewer.
