Abstract: An immersion nozzle exchanging apparatus and an upper nozzle capable of preventing damage to a plate of the upper nozzle are provided. An immersion nozzle exchanging apparatus is mounted on a lower portion of a molten steel outlet of a tundish. The immersion nozzle exchanging apparatus includes a support and a flap. The support has a support surface to support a lower surface of a plate of an upper nozzle inserted into the molten steel outlet. The flap is rotatable with respect to the support. The immersion nozzle exchanging apparatus further includes a rotation stopper for the flap. The rotation stopper includes a wedge to abut against the flap by projecting to an upper side of the flap, and a bolt connected to the wedge, and enables adjustment of a projection amount of the wedge by adjusting a fastening amount of the bolt.

Abstract: A system and a method are disclosed for tracking user activity with products in an environment. In an embodiment, a processor detects that a user has entered an environment, and responsively uniquely identifies the user. The processor determines that the user interacts with a product of a plurality of products within the environment, and responsively updates a profile of the user with indicia of the product. The processor determines whether the user is attempting to exit the environment, and, in response to determining that the user is attempting to exit the environment, prompts the user to confirm that the user intends to remove the product from the environment based on the updated profile. The processor receives input from the user confirming that the user intends to remove the product from the environment, and responsively further updates the profile based on the input.

Abstract: This disclosure relates method and system for protecting a computing device from a malware. In one embodiment, the method may include determining a digital trust certificate of a set of computing instructions to be executed by the computing device. The set of computing instructions may form a part of a boot process of the computing device, and may be a firmware, a boot loader, a kernel, a system driver, a start-up file, or an antimalware. The method may further include establishing a chain of trust by validating the digital trust certificate with the computing device. The digital trust certificate may be pre-registered with a local database, accessible by the computing device, by communicating with a centralized certificate authority and policy server. Upon a positive establishment of the chain of trust, the method may further include allowing an execution of the set of computing instructions by the computing device.

Abstract: A system and a method are disclosed for disambiguating between anonymous users associated with multiple transactions. In an embodiment, a system receives information about a transaction and generates a profile of the anonymous user associated with the transaction. In response to another transaction, the system compares the transactions to determine whether the same anonymous user is associated with both transactions. Upon determining that the same anonymous user is associated both transactions, the system adds information about the new transaction to the profile of the anonymous user.
