Interface for point of use data governance
The present system and method is directed to a process to facilitate trusted sources of information in an enterprise. The present system and method positions data governance to move away from the element level and focus on the data asset (i.e. repository, interface, subject) level. When data persons are having any issue with their data asset, whether it is a conflicting data asset, interface issues, competing data asset, new data asset build, data subject issue, or the like, a certifier may operate to assess the asset based on our well defined metrics, determine the health through the data asset scoring process, recommend asset services, and provide those services to the data owner who is ultimately responsible for implementing them to improve the data and the data processes. |

System and method for maintaining data consistency across replicas in a cluster of nodes using incremental validation
Data consistency across replicas in a cluster of nodes is maintained by continuously validating local data ranges and repairing any inconsistencies found. Local data ranges are split into segments and prioritized. After a segment is selected for validation, a hash value of a portion of the segment is compared to a hash value from other nodes storing replicas of that data. If the hash values match then the data is consistent. If the hash values do not match then the data is not consistent and whichever data is most current according to their timestamps is considered correct. If the local node data is correct, it is communicated to the replica nodes so they can be updated. If the local node data is not correct, then data from the replica nodes is correct and is used to update the data in the local node. An alternative, incremental validation approach improves efficiency. |

Handling file commit and commit-delete operations in an overlay optimizer
File commit and commit-delete operations can be successfully completed in environments that employ an overlay optimizer to enhance the performance of a write filter. The overlay optimizer can be structured into upper and lower instances relative to the write filter. The upper instance can cause files to be moved from the write filter's overlay into an overlay cache to thereby optimize the performance of the overlay. To prevent the failure of commit and commit-delete operations that target files that have been moved to the overlay cache, the lower instance can be configured to detect when the write filter is attempting to perform a commit or commit-delete operation and can modify the processing of such operations to cause them to be completed successfully even though the files targeted by the operations do not exist in the write filter's overlay. |

Intelligent energy switch
A method and associated systems for a self-learning energy switch. The switch creates an array of cognitive models for each candidate energy source. Each array returns a probability that its corresponding source is the most cost-effective and operationally suitable energy supplier at that time.

The system then automatically routes power from the optimal source to a consumer's energy-consuming premises. This self-learning procedure repeats indefinitely, continuously tuning the models in response to identifying additional extrinsic evidence and reasons why the system's previous energy selections were either optimal or non-optimal. |

Subsurface exploration using load tests on short model piles at various depths of a soil deposit for determining load-settlement relationship and engineering properties of soils and intermediate geomaterials
Subsurface exploration using In-Situ tests such as SPT, CPT, CPTu, DMT, and PMT predicts inaccurately engineering properties of soils and intermediate geomaterials and thereby predicts incorrect load-settlement relationship of piles; variations or errors in engineering properties predicted by one empirical correlation to another correlation could be up to 50% or greater. For soft to very soft soils, engineering properties cannot be predicted as the SPT only provides information such as WOR and WOH. To overcome this problem, the invention of the application consists of performing subsurface exploration using load tests on short model piles with or without instrumentation at various depths of a soil deposit for determining accurately the above-mentioned properties. For very soft soils, a hung balance is used to hang drill rods and short model pile from a drill rig boom or from a platform with soil anchors to prevent its overturning, and then perform the load test. |
