Abstract: A method of computing relative rankings for multiple course trajectories may include accessing a data structure. The data structure may include a first node that may represent a first course and a plurality of nodes that may represent courses that are available after completing the first course. Each of the plurality of nodes may be associated with a weight, and the plurality of nodes may include a second node representing a second course. The method may also include receiving a first grade for a student for the first course and receiving a second grade for the student for the second course. The method may additionally include adjusting the weight associated with the second node using the first grade and the second grade. The method may further include providing a ranking of the plurality of courses using the weights of the plurality of courses.

Abstract: Arrangements related to the confirmation of component connections made during manufacturing or assembly processes are described. Acoustic data resulting from the connection can be received by a microphone. A controller can analyze the acoustic information to determine if a predetermined acoustic signature is present in the acoustic information. Responsive to the determination, a confirmation signal can be generated and transmitted by the controller. One or both of the microphone and controller can be included in a wearable device and worn by a user. In some arrangements, a motion sensor can be included in the wearable device to allow determination whether motion data during a connection is acceptable.

Abstract: A computer (“patch analysis computer”) retrieves from a website, metadata describing one or more patch files to be used to change software in one or more computers (“target computers”). Prior to installation of the patch files in a target computer, the patch analysis computer performs analysis on the patch files and on the target computer and on application of the patch files to the target computer. The analysis is based on the retrieved metadata and based on configuration data of the target computer. Subsequent to performing the analysis, the management computer displays a report resulting from the analysis including one or more operations to fix issues found during analysis, and receives input from a human on specific patch files and operations. In response to receipt of human input, the patch analysis computer performs operations approved by the human and applies the patch files to the target computer.

Abstract: Some embodiments of the present invention provide a system for maintaining a software system. During operation, the system obtains a compliance policy for the software system and monitors the software system for a violation of the compliance policy. If a violation is detected, the system generates a change recommendation associated with the violation using the compliance policy and provides the change recommendation to an administrator, so that the administrator can use the change recommendation to resolve the violation.

Abstract: Some embodiments of the present invention provide a system that maintains a software system. During operation, the system obtains a compliance policy for the software system and monitors the software system for a violation of the compliance policy. If such a violation is detected, the system retrieves a change package associated with the violation based on the compliance policy and automatically deploys the change package to the software system to resolve the violation.
