Abstract: Embodiments may relate to pruning a distributed database for a peer-to-peer (P2P) network. A node may transmit a first multicast beacon over the P2P network. The node may receive a unicast synchronization request in response to the first multicast beacon, the unicast synchronization request comprising a removed list for the distributed database. The node may compare the removed list to a locally stored node list to determine a node removal. The node may determine if there is a failure in a node information call made to a node relating to the node removal. The node may, subsequent to a determination of the failure, update the locally stored node list based on the node removal. The node may transmit a second multicast beacon comprising the node removal. Nodes receiving the second multicast beacon may update a locally stored removed list using the node removal.

Abstract: A monitoring system for a mobile irrigation system that monitors the conditions or states of various electrical and/or mechanical components of the irrigation system and alerts an operator or automatically takes corrective action when conditions that may adversely affect operation of the irrigation system are detected. The monitoring system also monitors and records the locations of the irrigation system as it monitors the conditions or states of the electrical and/or mechanical components.

Abstract: An above-ground well shut-in safety apparatus, structure, and method useful for shutting-in wells during a blow-out is provided. The apparatus includes a top portion closing an upper end of an apparatus, a side wall with a long axis, a sleeve inside the side wall, and a bottom portion including an open end. A structure for shutting in a well, comprising a rig, a drive rigidly connected to the rig, and an apparatus rigidly connected to the drive, the apparatus including a tubular side wall, a top portion closing an upper end of the side wall, and a sealing sleeve inside the side wall. A method for shutting-in a well including driving an open end of an apparatus onto a stump of the well, the apparatus including a closed end opposite the open end and a tubular side wall with a sealing sleeve, and sealing the sleeve onto the stump.

Abstract: Systems and methods for biasing reroute to a user selected alternate route or a required route segment is provided. A network system receives an origin and a destination and determines a plurality of routes to navigate from the origin to the destination. The plurality of routes includes an optimal route and an alternate route. The network system receives, from a user device, a selection of the alternate route for navigation. The network system then monitors navigation of the alternate route by a user associated with the user device and detects deviation from the alternate route. In response to the detection, the network system determines a reroute by biasing to the alternate route over the optimal route. The reroute is then presented on the user device.

Abstract: A method of magnetization reversal, time stable ferrimagnetic material, a product and a domain comprising said material, a system for magnetization reversal, and information storage. Therein, a ferrimagnetic material is one in which magnetic moments of the atoms on different sublattices are opposed, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains.

Abstract: A bearing isolator seal includes a rotor and stator wherein the stator has inboard and outboard radial projections which define a groove bounded by groove side faces and a groove bottom face. The rotor extends radially and then axially so as to lie closely adjacent to the terminal end of the outboard radial projection on the stator to define an entrance passageway. The bearing isolator seal includes a surface geometry which is believed to result in improved exclusion of contaminants, particularly from high velocity water spray, wherein the entrance passageway is angled to increase the rotational effects of exclusion during shaft rotation, and wherein the groove side faces are also angled to assist in redirecting spray and other contaminants away from the passageway.
