Abstract: A multivariate anomaly detector can detect a cyber-attack using incremental malicious actions distributed across multiple devices in a network. A multivariate anomaly detector can collect input data describing communication connections between devices in the network. The multivariate anomaly detector can group the input data into a graph data batch based on a fixed batch increment of time to identify incremental actions. The multivariate anomaly detector can calculate a multivariate centrality score for two or more devices based on the graph data batch describing device centrality to the network. The multivariate anomaly detector can identify whether the two or more devices are in an anomalous state from normal device network interactions based on the multivariate centrality score to identify malicious activity distributed across multiple devices in the network.

Abstract: An apparatus for dewatering dredge spoils includes a floating barge having a planar upper surface or deck. One end of the barge, such as the stern, is partially flooded or otherwise ballasted so that the deck slopes downwardly from the bow toward the stem. Dredge spoils removed from a waterway are deposited onto the bow where they flow down toward the stem. A plurality of concrete blocks on the deck form an attenuator that, in turn, defines one or more settling ponds on the surface of the barge. A weir across the stem of the barge forms an additional settling pond at the rear of the barge. Solids suspended in the water removed from the waterway settle out onto the deck when the dredge spoils are deposited onto the bow. Remaining solids suspended in the water deposit onto the deck as the water flows through the settling ponds. The relatively clear water that remains then flows back into the waterway off the stem of the sloped barge after passing through the settling ponds.

Abstract: The invention provides novel apparatus for detecting and marking defects in flat glass advancing on a conveyor, for example a ribbon of float glass. There are two viewing stations on opposite sides of the center of the conveyor and spaced longitudinally so that there is staggered viewing of the two halves of the width of the advancing glass. Light reflected obliquely through each half is received on a viewing screen mounted above the respective side of the conveyor. Images of defects are recognized by examiners or cameras viewing the screens and the defects are marked by operation of appropriate marker guns positioned above the conveyor.
