Abstract: Some embodiments provide a method for migrating a set of data objects from a first database of a first database type to a second database of a second database type. The method receives a selection of the second database type and receives a selection of a user interface control for initiating the database migration from the first database of the first database type to the second database of the selected second database type. The method provisions the second database and transfers the set of data objects from the first database to the second database.

Abstract: Control strategy and algorithms to be utilized in a programmable logic control for automating injection rates of corrosion inhibitor and scaling inhibitor in a process plant. The logic control system can be programmed on a Distributed Control System (DCS) or Supervisory Control And Data Acquisition (SCADA) of the plant. The automating system is developed with the objective of optimizing corrosion inhibitor and scale inhibitor usage, thereby reducing operating cost, improving the reliability and integrity of process plant facilities, and preventing undesirable incident of loss of containment.

Abstract: For an updateable view that is defined for a first database, some embodiments provide an automated method for processing an update to data tuples in a second database, the update specified by reference to the updateable view. The method receives a first query from a client for modifying a particular data tuple presented in the updateable view. From a metadata storage, the method retrieves a definition of the updateable view, where the definition includes a reference to a first set of one or more objects associated with the particular data tuple in the first database. Based on the retrieved definition, the method generates a second query referencing a second set of one or more objects associated with the particular data tuple in the second database. The method executes the generated second query on the second database, to modify the particular data tuple in the second database.

Abstract: A modular patella trial system and method is provided. A modular patella trial includes an articular element and at least one sizing element. The articular element has a length, a width, and a thickness. The articular element has a posterior and anterior surfaces separated by their thickness. The anterior surface has protrusions extending outwardly. Any of the sizing elements have a length, width, and thickness. Any such sizing elements have posterior and anterior surfaces separated by their thickness. At least one aperture extends through the posterior and anterior surfaces of the sizing elements.

Abstract: A system and method for recycling flare gas back to a processing facility that selectively employs different numbers of ejector legs depending on the flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Valves are disposed in piping upstream of the flare gas and motive fluid inlets on the ejectors, and that are selectively opened or closed to allow flow through the ejectors. The flowrate of the flare gas is monitored and distributed to a controller, which is programmed to calculate the required number of ejector legs to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves, which open or close the valves to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas.
