Abstract: A method includes selecting one of a first safety architecture and a second safety architecture of a protection system configured to monitor a protection system. The protection system includes an input base, a controller base and an output base. The selecting includes selecting one of a first voting logic associated with the first safety architecture and a second voting logic associated with the second architecture. The controller base is configured to execute the selected voting logic. The method also includes configuring the protection system including a plurality of processing channels to operate in one of a first configuration associated with the first safety architecture and a second configuration associated with the second safety architecture. The configuring includes altering the number of processing channels releasably coupled to the protection system and hardware relay output in the protection system.

Abstract: An apparatus comprises a processing device configured to determine one or more testing goals for testing to be performed on one or more of a plurality of information technology assets of an information technology infrastructure and to select two or more of a plurality of testing plans based at least in part on scores assigned to respective ones of the plurality of testing plans, the assigned scores characterizing whether respective ones of the plurality of testing plans meet the determined one or more testing goals. The processing device is further configured to generate, utilizing one or more machine learning-based genetic algorithms that take as input the selected two or more testing plans, one or more additional testing plans, and to execute the one or more additional testing plans on the one or more of the plurality of information technology assets of the information technology infrastructure.

Abstract: A drilling device for surveying front rock-mass intactness of a tunnel face for a tunnel constructed by a TBM and a method using the same are provided. The drilling device includes a drilling assembly, a drill-attitude control assembly, a data monitoring assembly and a TBM-platform fixing seat. The drilling assembly is connected to a TBM hydraulic system to obtain power, to drill the rock mass by an alloy bit through rotation and translation thereof. The drill-attitude control assembly controls an angle, a direction and a position of a drill rod and maintains drilling accuracy and stability. The data monitoring assembly acquires and stores a drilling dynamic-response signal by a high-accuracy sensor and a data recorder, to analyze an intactness characteristic of the rock mass. The TBM-platform fixing seat mounts the drilling device on the TBM.

Abstract: Techniques for implementing snapshot sets for consistency groups of storage volumes in data storage systems. For each snapshot in a snapshot set of a consistency group, metadata is expanded to include a snapshot set identifier, and a consistency group identifier. The data structure of the consistency group is enhanced to include a snapshot set list, which includes the snapshot set identifier(s) of the consistency group, and a pointer to a storage volume list that contains names of storage volumes with snapshots in the snapshot set(s). By expanding the metadata of each snapshot in a snapshot set, and enhancing the data structure of each consistency group with snapshot set(s), relationships between snapshots, snapshot sets, consistency groups, and storage volumes can be readily maintained, allowing storage volumes to be added to and/or removed from consistency groups without having to delete snapshots of the storage volumes and/or snapshot sets of the consistency groups.

Abstract: Systems and methods are provided for the manipulation of a polarizable object with a pair of elongated nanoelectrodes using dielectrophoresis. The nanoelectrodes can be carbon nanotubes and are coupled with one or more time-varying voltage sources to create an electric field gradient in a gap between the nanotubes. The gradient induces the movement of a polarizable object in proximity with the field. The nanotube pair can be used to trap a single polarizable object in the gap. A method of fabricating a nanoelectrode dielectrophoretic system is also provided. Applications extend to self-fabricating nanoelectronics, nanomachines, nanochemistry and nanobiochemistry. A nanoelectrode dielectrophoretic system having an extended nanoelectrode for use in applications including the self-fabrication of a nanowire, as well as methods for fabricating the same, are also provided.
