Abstract: Implementations are described related to users directly manipulating visual depictions of aspects of a data set displayed in a user interface to generate or modify visual representations of the data set, such as a chart. The direct manipulation may be either through a computer input device, (e.g., a keyboard or mouse), or based on other input data, such as a touch input. Aspects of a data set include dimensions, which may be used to filter the data set, and metrics, which are quantifiable elements within the data set. In various implementations, input such as drag-and-drop operations corresponding to visual depictions of aspects of a data set may be interpreted in generating or modifying charts.

Abstract: Described is a technology, such as implemented in a computational software program, by which a minimal polynomial is efficiently determined for a radical expression over the ring Z of integer numbers or the ring Q of rational numbers. The levels of the radical are grouped into a level permutation group that is used to find a level permutation set. An annihilation polynomial is found based upon the level permutation set. The annihilation polynomial is factored, and a selection mechanism selects the minimal polynomial based upon the annihilation polynomial's factors.

Abstract: Techniques for detecting, analyzing, and/or reporting code clone are described herein. In one or more implementations, clone-code detection is performed on one or more source code bases to find true and near clones of a subject code snippet that a user (e.g., a software developer) expressly or implicitly selected. In one or more other implementations, code clone is analyzed to estimate the code-improvement-potential (such as bug-potential and code-refactoring-potential) properties of clones. One or more other implementations present the results of code clone analysis with indications (e.g., rankings) of the estimated properties of the respective the clones.

Abstract: Techniques for mining API method usage patterns from source code are described. These techniques include parsing the source code to generate API method call sequences that include an API method. These call sequences are clustered to obtain clusters. Based on the clusters, frequent closed sequences are determined and then clustered to obtain an API usage pattern. In addition, optimal clustering parameters may also be determined. In some instances, a graphical representation is generated based on the API usage pattern in response to a query associated with the API method.

Abstract: A method and an apparatus for authentication are disclosed. The method includes: deciding to release a connection or continue a current service according to native information and network policy after an AKA authentication procedure fails. When the EPS AKA authentication procedure fails, the connection is not released immediately in the present invention, but the connection is released or the current service is continued according to the native information and network policy, thus avoiding unnecessary release of connections and saving resources.

Abstract: A method and an apparatus for protecting data carried on an Un interface between a eNB and a relay node are disclosed. Three types of radio bearers (RBs) are defined over the Un interface: signaling radio bearers (SRBs) for carrying control plane signaling data, signaling-data radio bearers (s-DRBs) for carrying control plane signaling date; and data-data radio bearers (d-DRBs) for carrying user plane data. An integrity protection algorithm and an encryption algorithm are negotiated for control plane signaling data on an SRB, control plane signaling data carried on an s-DRB, and user plane data carried on a d-DRB. With the respective integrity protection algorithm and encryption algorithm, the data over the Un interface can be protected respectively. Therefore, the security protection on the Un interface is more comprehensive, and the security protection requirements of data borne over different RBs can be met.

Abstract: Techniques for error report processing are described herein. Error reports, received by a developer due to program crashes, may be organized into a plurality of “buckets.” The buckets may be based in part on a name and a version of the application associated with a crash. Additionally, a call stack of the computer on which the crash occurred may be associated with each error report. The error reports may be “re-bucketed” into meta-buckets to provide additional information to programmers working to resolve software errors. The re-bucketing may be based in part on measuring similarity of call stacks of a plurality of error reports. The similarity of two call stacks—a measure of likelihood that two error reports were caused by a same error—may be based in part on functions in common, a distance of those functions from the crash point, and an offset distance between the common functions.
