  • AUTOMATED WELL-LOG CORRELATION USING DESCRIPTORS
    Publication number: 20190383133
    Abstract: Well logs can be automatically correlated using dynamic warping with descriptors. For example, a computing device can receive user input indicating a manual correlation between a first node in a first well-log and a second node in a second well-log. The computing device can use the manual correlation to automatically determine a combination of descriptors usable to correlate the first node to the second node. The computing device can then perform dynamic warping on other well logs using the combination of descriptors determined by using the first well log and the second well log. This may provide more accurate correlations between well logs.

  • Coverage of call graphs based on paths and sequences
    Patent number: 10248547
    Abstract: Some embodiments provide a program that collects a set of call stack data associated with a set of test cases executed on an application. The program further generates a set of call graphs based on the set of call stack data. Each call graph in the set of call graphs includes a set of nodes representing a set of functions in the application executed in the corresponding test case in the set of test cases. The program also determines, for each call graph in the set of call graphs, a set of short paths and a set of short sequences in the call graph. The program further receives a notification indicating a modification to a function in the application. The program also determines a subset of the set of test cases to test the modification to the function based on the sets of short paths and the sets of short sequences in the set of call graphs.

  • Accessing resources in private networks
    Patent number: 10171240
    Abstract: Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives a queue message from a computing device. The queue message includes a request to perform a set of actions on a resource in a private network and a security signature generated from an authentication operation. The program also stores the queue message in a message queue for later retrieval when the queue message is determined to be valid based on the security signature. The program further sends the queue message to a queue monitor for the queue monitor to instruct the resource to perform the set of actions. Upon receiving a response associated with the queue message from the queue monitor, the program forwards the response associated with the queue message to the computing device.
