Abstract: A first set of code origination data which corresponds to a first computing object and a second set of code origination data which corresponds to a second computing object may be detected for utilization to develop a streaming application in the stream computing environment. Based on the first and second sets of code origination data, a code assembly arrangement with respect to the first and second computing objects may be determined. Based on the first and second sets of code origination data, a consistent region may be determined to utilize for the code assembly arrangement. The code assembly arrangement may be established, in the consistent region, with respect to the first and second computing objects to develop the streaming application.

Abstract: A computing system for tampering detection for digital images is disclosed. The computing system uses a LTI filter to filter time series data representing images in one or both of two videos and/or a still image of a live photo captured by a camera. A causal relationship in time existed between the images in the two videos and the still image when they were captured by the camera. The computing system determines whether the filtered output data representing an image by using the LTI filter is causal. If the computing system determines that the filtered output data representing the image is non-causal, it asserts a signal indicating that the image has been modified after it was captured.

Abstract: Disclosed aspects relate to checkpointing a set of stream computing data with respect to a stream computing environment having a set of windowed stream operators including both a first windowed stream operator and a second windowed stream operator. It may be identified that the first windowed stream operator has a first subset of the set of stream computing data. It may be identified that the second windowed stream operator has the first subset of the set of stream computing data. It may be determined to checkpoint the first subset of the set of stream computing data without a redundant checkpoint related to the first and second windowed stream operators. The set of stream computing data may be checkpointed without the redundant checkpoint of the first subset of the set of stream computing data.

Abstract: A streams controller monitors multiple data streams with speech of a conversation with multiple speakers and uses text analytics and diaritization to identify speakers by their role in the conversation. Diaritization is applied to the audio of a data stream to associate a speaker with an SSRC from the data stream and a speaker identification (ID). The streams controller then runs text analytics on a text version of the speaker's speech to determine a speaker role for the speaker. The speaker role can be used to efficiently monitor conversations in a data stream to provide additional services. For example, speaker role can be used to analyze calls in a call center and provide services such as a transcript of conversations or enhanced customer support.

Abstract: An ophthalmic device is described that includes a frame and an optically active component comprising a bistable dielectric electroactive polymer. The bistable dielectric electroactive polymer changes shape when exposed to a sufficiently strong electric field and does not completely revert to its former shape when the electric field is deactivated. The refractive properties of the ophthalmic devices described herein are adjusted by exposing the devices to electric fields.

The operator split mechanism can operate in an automatic mode where operators are split without further input from the user, or in a more interactive mode where the operator split mechanism provides recommendations and options to a user, who makes appropriate selections, and the operator split mechanism then functions according to the selections by the user.
