Abstract: An aircraft weight and balance system includes a user interface that displays an interior layout of an aircraft with seat icons and cargo icons corresponding to seats and cargo zones onboard the aircraft. The seat and cargo icons are moveable to different locations within the interior layout, and an updated weight and center-of-gravity of the aircraft is automatically determined based on the different locations of the seat and cargo icons. An aircraft weight and balance method includes displaying an interior layout of an aircraft on a user interface including seat icons corresponding to seats onboard the aircraft, moving one or more of the seat icons to a different location within the interior layout based on a user input, determining an updated weight and center-of-gravity of the aircraft based on a current location of the seat icons, and displaying the updated weight and center-of-gravity of the aircraft on the user interface.

Abstract: An apparatus, method and computer program product for estimating as-a-Service (aaS) query prices in a relational database management system (RDBMS). An optimizer of the RDBMS inserts an EXPLAIN modifier into a query, wherein the EXPLAIN modifier results in the optimizer generating a summary of a query execution plan for the query that includes one or more cost estimates for the RDBMS to perform the query. A price estimate for the query is then generated based on the cost estimates, wherein the price estimate is generated using one or more configurable pricing formulae. The price estimate is merged into the summary of the query execution plan for the query. Moreover, a price guarantee may be generated for the price estimate, wherein the price guarantee is honored when the query is subsequently invoked for execution by the RDBMS.

Abstract: A system and method for determining optimal query plans within a distributed processing system. The system includes a query optimizer for receiving a query and generating a query plan for execution by the distributed processing system; a repository including statistics related to prior executed query plans; a plan execution engine for receiving and executing the query plan, collecting statistics corresponding to the query plan, and storing the statistics and optimizer usage metadata corresponding to the query plan and prior executed query plans in the repository. The system further includes a statistics advisory tool for mining the metadata to generate a collection of histogram statistics and storing said histogram statistics in the repository. When generating a query plan, the query optimizer searches the statistics repository for statistics, including histogram statistics, useful to the generation of the current query plan and uses selected statistics from the repository to generate the query plan.

Abstract: Data portions of a database can be grouped and ranked in order of priory for reassignment from one or more maps to another one or more maps. It should be noted that a first map can assign the data portions to a first configuration of processors for processing the data portions, and a second map assigns the data portions to a second configuration of processors, different than the first configuration, for processing the data portions in a database system and/or environment. The data portions are reassigned in groups during an available time (window) for reassignment by taking the first one of the groups can be reassigned (“moved”) in the available, then the second one in the available reaming time, and so on, until no group of data portions can be moved in the remaining time or all of them have been moved.

Abstract: Data of a database (e.g., database tables) can be reassigned from a first map to a second map in a database system that uses maps to assign data for processing to multiple processing units of a database system in accordance with one or more distributions schemes. Data portions can be selected in groups and moved in the selected groups in an efficient manner. The selection and/or movement of the data portions can be automated without requiring input for users of database systems.

Abstract: A method is disclosed for detecting atmospheric turbulence including aircraft induced wake turbulence and/or wind shear within an aperture associated with an aircraft approach or departure corridor around an airport. The method comprises transmitting into the aperture acoustic signals having a waveform suitable for pulse compression and receiving backscattered acoustic echoes of the acoustic signals from the atmospheric turbulence and/or wind shear. The method further includes processing the acoustic echoes in a matched filter receiver to provide a measure of the atmospheric turbulence and discriminating the aircraft induced demise time, being a time taken for the aircraft induced wake turbulence and/or wind shear to fall below a set threshold at least in the aperture. A system for detecting atmospheric turbulence including aircraft induced wake turbulence and/or wind shear associated with an aircraft approach or departure corridor around an airport is also disclosed.

Abstract: An order (or priority) for reassigning data portions of a database from a first map to a second map can be determined. It should be noted that the first map assigns the data portions to a first configuration of processors for processing the data portions, and the second map assigns the data portions to a second configuration of processors, different than the first configuration, for processing the data portions in a database system and/or environment. The order can be determined by grouping the data in multiple groups and ordering the groups in accordance with a determined priority for reassignment. In doing so, one or more relationships between the data portions and/or cost of use for each one the groups can be considered.
