Abstract: Infill-to-parent well frac hits or fracture driven interactions occur when infill well fractures intersect with parent well depleted fractures or parent wellbores themselves. As a result, both the parent and infill well production can be negatively impacted. Understanding and mitigating frac hits is crucial for unconventional assets since they can impact many aspects of field development. Frac hits can cause parent well production loss, making it an important consideration when it comes to well spacing-stacking, completion design, and drilling schedules optimization decisions. In cases where parent wells have been knocked offline by frac hits, well interventions are often necessary to restore production. Refracturing of parent wells has been proven to protect them from offset infill frac hits, and also presents a secondary field development opportunity.

Abstract: Aspects of the subject technology relate to a shaker module for an electronic device. The shaker module may include a movable component that is resiliently suspended in relation to a voice coil by one or more gap-separated pairs of the flat springs. The flat springs reduce the z-height of the shaker module for implementation in, for example, compact electronic devices. The gap-separated pairs of flat springs facilitate adjustment of the resonance frequency of the shaker module substantially independently of adjustments to drop performance, while providing stability against unwanted rocking motions of the movable component.

Abstract: Mechanisms are provided for automatically predicting vehicle weight of a moving vehicle. Vehicle operation data is obtained from one or more on-board sensors/systems of the vehicle and features are extracted. The features are filtered based on a required working condition of the vehicle to identify intervals of features having valid feature data to thereby generate a filtered valid data. The filtered valid data is processed by a first artificial intelligence (AI) computer model based on time slices of the filtered valid data to generate a first prediction of vehicle weight, and by a second AI computer model based on buckets of key variables to generate a second prediction of vehicle weight. The first prediction is fused with the second prediction to generate a final prediction of vehicle weight which is output to downstream computing logic.

At least one of the randomly selected version numbers associated with at least one node in a level differs from the initial version number associated with a versionf. A best successful installation path is selected from the at least one successful installation path. The Dockerfile is repaired by inserting randomly selected version numbers into Dockerfile as replacements for some of the initial version numbers.
