Abstract: The present disclosure provides a thermal-stress-pore pressure coupled electromagnetic loading triaxial Hopkinson bar system and test method, the system mainly consists of an electromagnetic pulse generation system, a servo-controlled axial pressure loading system, a servo-controlled confining pressure loading system, a thermal control system, a pore pressure loading system, a bar system, and a data monitoring and acquisition system. Based on the conventional Hopkinson bar, the present disclosure creatively introduces a real-time loading and control system for confining pressure, thermal, and pore pressure, aiming to solve the technical problem that the existing test apparatus cannot be used to study dynamic response of deep rock mass under the coupling effect of thermal-stress-pore pressure and dynamic disturbance during dynamic impact loading.

Abstract: A uniaxial bidirectional synchronous control electromagnetic loaded dynamic shear test system and method, a test apparatus thereof including a support platform, a loading bar system, an electromagnetic pulse generation system, a servo-controlled normal pressure loading system, and a data monitoring and acquisition system. The test apparatus can be used to conduct a dynamic shear test research on a rock-like material under a constant normal pressure close to an actual operating condition, and can also be applied to carry out dynamic shear tests on intact rock-like test specimens in various sizes or jointed rock-like test specimens containing a single structural surface to study dynamic shear mechanical property and shear failure behavior under strain rate of 101?103 s?1, thereby providing an important theoretical and technical support for the design, construction, protection, and safety and stability evaluation of geotechnical engineering, structural engineering.

Abstract: Systems, methods, and non-transitory computer-readable media can receive a first content item uploaded by a first user. Content ownership information can be updated to associate the first content item with the first user. The first user can be provided with content item analytics pertaining to the first content item in a content item analytics interface.

Abstract: In one embodiment, a method includes a computer server machine receiving a request from a first user to interact with a multimedia content. The computer server machine then associates the first user with a control group, wherein the control group comprises a first set of users interacting with the multimedia content. When the first user is associated with the control group, the computer server machine then applies a first content insertion model to the multimedia content and records a first set of metrics based on the interaction of the first user with the multimedia content.

Abstract: Systems, methods, and non-transitory computer-readable media can receive revenue for a first content item. It can be determined, based on content ownership information, that the first content item is associated with a plurality of content owners. The revenue can be allocated between the plurality of content owners based on the content ownership information.
