Abstract: A method, computer system, and a computer program product are provided for backup and restoration of data. Data is obtained from a plurality of resources during a plurality of tasks. The resources are located in one or more computing networks. A plurality of parameters are extracted from obtained data. A table is generated and stored that includes the parameters extracted and an associated related task. A predict time is calculated based on the table for recovery of data when any of the resources become unavailable. A task priority is established based on calculated predict time and the table to optimize and improve the predict recovery time. A restoration model is generated based on updated restoration recommendation. The restoration model is to be used during resource unavailability or failure of one or more of the resources.

Abstract: The present disclosure is directed to a multi-variant control system for an industrial facility. In one form of a method, a processor monitors a behavior of a distributed control system with respect to at least a set of uncontrolled variables, a set of controlled variables, and a set of monitored variables; trains a model based on the monitored behavior utilizing at least one of artificial intelligence or machine learning; and identifies, based on the model, a subset of controlled variables for optimization.

Abstract: A method of operating a personal safety system including a vehicle includes automatically detecting that a smartphone is within a communication range using a wireless communication system of the vehicle, and starting an approach time period with a controller of the vehicle or the smartphone when the smartphone is detected. The method further includes sending checkup data from the vehicle to the smartphone using the wireless communication system when the smartphone fails to arrive at the vehicle prior to the approach time period elapsing, and triggering an emergency response by the vehicle and/or the smartphone when the vehicle fails to receive a response to the checkup data from the smartphone within a response time period.

Abstract: A locking assembly for locking a ground engaging tool such as a shroud to a bucket lip. The bucket lip has a C-shaped boss fixed thereto. The ground engaging tool has a recess to receive a lock, the recess having an opening which is shorter in axial length than the recess. The lock is arranged to pivot about the boss as the ground engaging tool is slid rearwardly relative to the bucket lip. When the lock is located entirely within the recess, it can be accessed through a rear tunnel and tightened to hold the assembly in place.

Abstract: The present invention provides an integrally configured flow channel system for application in the basic structure of a paintball gun, which enables increasing speed of vaporization to produce a high working pressure. The structure is solid, and maintains high safety for the operating mechanism. The system mainly includes a gun main body having a long rectangular shape and provided with heat conducting properties, and is longitudinally defined with a bolt. A chamber is defined parallel to the bolt, and a pre-vaporizer is longitudinally defined close to the chamber and the inner surface bordering on the exterior of the gun main body. One end of the pre-vaporizer affords passage to the chamber, and another end is joined to a pressure source through a lead-in port. The pre-vaporizer effectively uses the heat effectively exchanged from the heat stored by the gun main body.
