Abstract: Embodiments detect and predict data disparity issues in data warehouses. Embodiments derive meaningful insights about the events occurred prior to the data disparity and correlate the events to understand the root cause of the data disparity (or the root cause of an alert generated as a result of detecting the data disparity). Embodiments either take or recommend actionable measures to prevent further occurrences of the event identified as the root cause. According to various embodiments, when the monitored data is transaction data (e.g. transaction volume, transaction amount, transaction processing speed, etc.), internal events (e.g. data job failures, job delays, job server maintenances) or external events (e.g. seasonal holiday events, natural calamities) may cause a dip or spike in the transaction data resulting in a data quality anomaly (i.e. a data disparity).

Abstract: A system includes a turbine exhaust section having an exhaust flow path, an inner exhaust wall radially disposed along the exhaust flow path, an outer exhaust wall disposed radially outward of the inner exhaust wall and along the exhaust flow path, and a flow control vane extending between a first end and a second end. The first and second ends are circumferentially offset from one another. The flow control vane is configured to move between a retracted position along the outer exhaust wall and an extended position extending from the outer exhaust wall toward the inner exhaust wall. The second end is disposed radially inward from the first end while the flow control vane is disposed in the extended position.

Abstract: An apparatus includes a first chamber, a second chamber, and a third chamber. The first chamber includes an alkaline solution, a gas inlet to receive carbon dioxide-containing gas, and a gas outlet. The first chamber outputs a solution containing a first metal carbonate containing a first metal to the second chamber via a first channel, and the second chamber outputs a solution containing a first metal hydroxide containing the first metal to the first chamber via a second channel. The third chamber is configured to perform an electrochemical reaction to convert a mineral containing a second metal to a second metal hydroxide containing the second metal. The third chamber is coupled to the second chamber via a third channel and outputs the second metal hydroxide containing the second metal to the second chamber via the third channel.

Abstract: A free space input standard is instantiated on a processor. Free space input is sensed and communicated to the processor. If the free space input satisfies the free space input standard, a touch screen input response is invoked in an operating system. The free space input may be sensed using continuous implicit, discrete implicit, active explicit, or passive explicit approaches. The touch screen input response may be invoked through communicating virtual touch screen input, a virtual input event, or a virtual command to or within the operating system. in this manner free space gestures may control existing touch screen interfaces and devices, without modifying those interfaces and devices directly to accept free space gestures.
