Abstract: A method of detecting anomalous user behavior in a cloud environment includes calculating a first vector that is representative of actions taken during a plurality of previous time intervals; calculating a similarity between the first vector and a second vector that comprises counts of actions taken by the user during a current time interval; comparing the similarity to a baseline threshold to determine whether one or more anomalous actions have occurred; and generating an alert based at least in part on a determination that the one or more anomalous actions have occurred in the cloud environment.

Abstract: An LED flat light and a manufacturing method thereof including processes of preparing a substrate, mounting a support, dispensing an under-fill, mounting an LED chip, wire bonding, dispensing fluorescent powder, and LED packaging; and the finished product of LED flat light includes a substrate provided with multiple insertion holes, each hole being disposed to its peripheral a positive golden finger and a negative golden finger; multiple LED modules electrically connected to one another for each module corresponding to one insertion hole; the insertion hole includes a support comprised of a base and a base cup with the base cup placed in the insertion hole; an LED chip being fixed in the base cup; and both positive and negative electrodes of the LED chip being electrically connected to their corresponding golden fingers on the substrate; the LED chip being covered up with a fluorescent powder layer, where in turn being covered up with a sealing layer to allow firm combination among member of the LED flat ligh
