Abstract: A dynamic facial expression recognition (FER) method based on a Dempster-Shafer (DS) theory improves a feature extraction effect of an expression video through multi-feature fusion, and deeply learns an imbalanced dynamic expression feature by using the DS theory, multi-branch convolution, and an attention mechanism. Compared with other methods, the dynamic FER method scientifically and effectively reduces an impact of sample imbalance on expression recognition, fully utilizes a spatio-temporal feature to mine potential semantic information of the video expression to perform expression classification, thereby improving reliability and accuracy and meeting a demand for the expression recognition.

Abstract: A sound absorber is configured as a rectangular hexahedral box and forms a porous double-layer Helmholtz resonance sound absorbing structure, at the same time, the sound absorber in the form of a box forms a structural resonance sound absorbing device itself, and the first-order natural mode frequency of the device is identical to that of a wheel air chamber. When the box-type sound absorbing structure is assembled in a wheel, double functions of absorbing acoustic resonance of the wheel air chamber under the organic combination of Helmholtz resonance sound absorption and structural resonance sound absorption can be realized.

Abstract: A computer readable storage medium includes executable instructions to receive a check-in indication from a physical location with a corresponding virtual location in a virtual game. An attribute in the virtual game is altered based upon the check-in indication. The attribute may be earned points for a user, a virtual object earned by a user or an enhanced popularity measure for the virtual location.

Abstract: Aspects of the subject matter described herein relate to simulating storage devices. In aspects, a test automation engine instructs a simulator to simulate a storage device having certain characteristics such as a storage area network. The test automation engine then tests an application against the simulated storage device. Tests may include storage management requests and storage access requests. A provider may translate a request to one or more operations suitable to perform the request on the underlying simulated device. Shadow copies and the results of other storage management-related operations may be shared across computers via aspects of a simulation framework described herein.
