Abstract: A computer-implemented method for anonymously selecting streams for analysis is described. In one embodiment, control information that associates one or more telemetry feeds with one or more multicast sources is identified. One or more multicast sources are joined based on the received control information and data from the multicast source is analyzed based on one or more data analysis parameters.

Abstract: The disclosed computer-implemented method for verifying the authenticity of graphical images may include (1) identifying a graphical image intended for presentation by a display and then, prior to facilitating presentation of the graphical image by the display, (2) identifying an original unique identifier of at least a portion of the graphical image encoded into the graphical image, (3) computing a subsequent unique identifier of the portion of the graphical image, and (4) determining, by comparing the subsequent unique identifier to the original unique identifier, whether the graphical image is authentic. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for securing data and computer systems is described. In one embodiment, a request to connect to a server is received at an intermediary network device. It is detected, at the intermediary network device, that the server uses a one-time password (OTP) protocol. Based at least in part on the detecting that the server uses an OTP protocol, an action is performed by the intermediary network device. The action may include blocking, at the intermediary network device, a connection other than the connection to the server that uses the OTP protocol.

Abstract: Lithium disilicate based glass-ceramics contain high strength ceramic components for use in the manufacture of dental products. The glass-ceramics have good pressability, i.e., the ability to be formed into dental products by heat-pressing using commercially available equipment. The strength of the dental articles is increased with the inclusion of the high strength ceramic components.

Abstract: Solid free form fabrication techniques such as fused deposition modeling and three-dimensional printing are used to create a shell used in the manufacture of a dental restoration. Three-dimensional printing includes ink-jet printing a binder into selected areas of sequentially deposited layers of powder. Each layer is created by spreading a thin layer of powder over the surface of a powder bed. Instructions for each layer may be derived directly from a CAD representation of the restoration. The area to be printed is obtained by computing the area of intersection between the desired plane and the CAD representation of the object. All the layers required for an aesthetically sound shell can be deposited concurrently slice after slice and sintered/cured simultaneously.

Abstract: Digital ad insertion methods and apparatus permit timely and correct switchovers from network programming to local advertising in ways which occur smoothly without a disruption in perception to the viewer. Switchovers occur at packet or frame boundaries and are designed to occur upon detection of idle information from a network source.

Abstract: A plurality of network analyzers are combined into a network performance analysis tool for analyzing complex and widely distributed networks. Each of the network analyzers is synchronized with the others to provide consistency in the application of timestamps to packets traversing the network. Data from all of the analyzers is aggregated and sorted chronically and a variety of processing performed to determine important performance information about various components of the network. This information can then be used directly in simulation of a fully deployed network environment.

Abstract: A dental alloy is provided which is compatible with a wide variety of composites and porcelain compositions. The alloy has a melting range of between about 870.degree. C. and 1230.degree. C. and a coefficient of thermal expansion of between 15.5.times.10.sup.-6 and 17.5.times.10.sup.-6 in/in/.degree. C. when heated from room temperature to 500.degree. C. The alloy contains between one and 85 percent by weight gold, between two and 65 percent by weight of a thermal expansion adjuster, between 0.25 and 34 percent by weight of a strengthener and oxide former, up to about one percent by weight grain refiner, and up to about 0.25 percent by weight deoxidizer.

Abstract: A dental composite cartridge is made of a plastic material molded to define an elongated cylindrical hollow body portion forming a reservoir, and a discharge nozzle portion. A piston is disposed within an open end of the hollow body after the body is filled with dental composite material. The hollow body and the discharge nozzle define a planar end wall which intersects the longitudinal axis of the hollow body at an angle of about 45.degree.. The interior design of the hollow body and its angled planar end wall enables a simple, easy to manufacture and cost-effective piston to be used in the hollow body for discharging dental composite material from the reservoir.
