Abstract: Disclosed in the present application is a lithium-aluminosilicate glass. The lithium-aluminosilicate glass includes, by mole percent of oxides, the following components: SiO2, 62-68 mol %; Al2O3, 9-14 mol %; Na2O, 6-10 mol %; K2O, 0.2-0.7 mol %; and Li2O, 8.0-14.0 mol %; where (Li2O+Na2O+MgO)/Al2O3 is 1.7-2.5. By means of controlling the mole percents of SiO2, Al2O3, Na2O, K2O, and Li2O, as well as the range of the ratio (Li2O+Na2O+MgO)/Al2O3, it is consequently ensured that the obtained lithium-aluminosilicate glass, upon chemical strengthening, has high strength, satisfies a requirement of a client with respect to “film-peeling electrostatic voltage”, and further has uniquely advantageous effects of a lower melting temperature and being able to save energy and reduce energy consumption.

Abstract: Techniques are disclosed relating to sharing a user credential between computing devices. In some embodiments, a first computing device stores a set of user credentials usable to authenticate a user and receives, from a second computing device, a request for a user credential to be provided responsive to an authentication prompt associated with the second computing device. In such an embodiment, the request includes an indication of a service for which the authentication prompt is being presented. Based on the indication, the first computing device determines whether the stored set of user credentials includes a user credential relevant to the authentication prompt and presents a selection prompt asking a user of the first computing device to select a one of the stored set of user credentials to provide to the second computing device for authentication to the service, the relevant user credential being identified in the selection prompt.

Abstract: Described is a system (and method) for automatically populating login credentials for an application such as a third-party application (or app) installed on a device. These applications are often associated with an entity that may operate or control a website, service, or another application. For example, browsers often store login credentials (e.g. username and password) of previously visited websites. Accordingly, the system may retrieve applicable login credentials for the application in response to verifying the application is authorized to be associated with the website associated with the retrieved password. Accordingly, the system may provide a convenient and safe mechanism to retrieve applicable login credentials even in instances where a developer of the application has not provided an explicit capability of such a feature.

Abstract: The present method for testing the bonding strength of rock bolt-grout-surrounding rock comprises the following steps: step 1, fabricating the simulative body of a rock bolt provided with a first surface, wherein the concave-convex characteristic of the first surface is consistent with the surface appearance of a rock bolt, and the first surface is a plane; step 2, pouring a grout layer for simulating the grout material on the first surface of the simulative body of the rock bolt; step 3, pouring a surrounding rock layer for simulating the surrounding rock material on the solidified grout layer, wherein the simulative body of the rock bolt, the grout layer and the surrounding rock layer form a simulative anchoring body; and step 4, performing a shear test along the simulative stress direction of the simulative anchoring body to obtain mechanical parameters reflecting the bonding strength of the anchoring body.

Abstract: A computer implemented decision support tool serves as a solver to generate a best can do (BCD) match between existing assets and demands across multiple manufacturing facilities within boundaries established by manufacturing specifications and process flows and business policies to determine which demands can be met in what time frame by microelectronics (wafer to card) or related (for example disk drives) manufacturing and establishes a set of actions or guidelines for manufacturing to incorporate into their manufacturing execution system to insure the delivery commitments are met in a timely fashion. The BCD tool has six major components, a material resource planning explode or "backwards" component, an optional STARTS evaluator component, an optional due date for receipts evaluator, an optional capacity available versus needed component, an implode "forward" or feasible plan component, and a post processing algorithm.
