Abstract: To monitor semiconductor manufacturing process variation, contours of identical pattern features are determined based on SEM images, and the contours are aggregated and statistically analyzed to determine the variation of the feature. Some of the contours are outliers, and the aggregation and averaging of the contours “hides” these outliers. The present disclosure describes filtering certain outlier contours before they are aggregated and statistically analyzed. The filtering can be performed at multiple levels, such as based on individual points on the contours in the set of inspection contours, or based on overall geometrical shapes of the contours in the set of inspection contours.

Abstract: Techniques and apparatus for parameter error detection in a power system based on state estimation are described. In one embodiment, for example, an efficient process may be used to derive and compute only the necessary subset of the gain matrix and covariance matrix, thus avoiding the computation and storage of large dense matrices. The described efficient process can be applied either to single-scan or multiple-scan schemes. Other embodiments are described.

Abstract: A method for communicating with a call center, is performed at a client device having one or more processors and memory. The client device establishes, via an instant messaging application running on the client device, a network session connection to the call center by using an audio and video server. The client device receives, through the network session connection, a first-level voice menu sent by the call center. The client device obtains a correspondence between visualized menus and voice menus of the call center. The device searches for a first visualized menu corresponding to the first-level voice menu according to the correspondence. The client device presents the first visualized menu in a user interface of the instant messaging application and plays information about an option in the first visualized menu in an on-demand voice manner in response to user input detected on the option in the user interface.
