20130188564 | RESOURCE ALLOCATION IN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEM - A scheduler performs per sub-band prioritization allocation of sub-bands to user terminals to generate a pre-allocation schedule. The prioritization is performed independently for each sub-band. The resulting pre-allocation schedule indicates the relative priorities of the user terminals for each sub-band taking into account the channel conditions and specific needs of the user terminals. Based on the pre-allocation schedule, the scheduler can more efficiently allocate the radio resources to the user terminals based on the channel conditions and the specific needs of the user terminals. The scheduling approach is suitable for parallel computing architectures. The use of a parallel computing architecture increases MIPS (million instructions per second) capacity and allows faster scheduling in order to meet stringent real-time constraints. | 07-25-2013 |

20160132828 | REAL-TIME CONTINUOUS REALIGNMENT OF A LARGE-SCALE DISTRIBUTED PROJECT - A method and associated systems for real-time continuous realignment of a large-scale distributed project. A project-management system, consisting of a computer system, a data warehouse, and remote data-aggregation subsystems, receives project artifacts that describe goals, scope, contractual obligations, and other characteristics of a large-scale project. The distributed system extracts from the artifacts baseline values of benchmarks that measure project progress. Project workers located at multiple sites continuously feed the project-management system, via the data-aggregation subsystems, data describing actual progress on the project. The baseline values and actual-progress values are imported into the data warehouse in a compatible format. The data-warehouse data is then used to generate recommendations intended to resolve problems indicated by the current-progress values, which are then communicated to project managers, who implement them as action plans. The procedure repeats until benchmarks indicate that project parameters have been realigned so as to ensure desired project results. | 05-12-2016 |
