Abstract: Some aspects of what is described here relate to seismic profiling techniques. A seismic excitation is generated in a first wellbore in a subterranean region. Seismic responses associated with the seismic excitation are detected by an array of seismic sensors in a second wellbore in the subterranean region. A first subset of the seismic sensors is distributed along a directional section of the second wellbore; a second subset of the seismic sensors is distributed along a vertical section that extends through a plurality of subsurface layers. A fracture treatment of the subterranean region is analyzed based on the seismic responses.

Abstract: Some aspects of what is described here relate to seismic data analysis techniques. A seismic excitation is generated in a first directional wellbore section in a subterranean region. A seismic response associated with the seismic excitation is detected in a second directional wellbore section in the subterranean region. Seismic response data based on the seismic response are analyzed to identify geomechanical properties of subterranean rock in a fracture treatment target region in the subterranean region. In some cases, the geomechanical properties include pore pressure, stress, or mechanical properties.

Abstract: Some aspects of what is described here relate to seismic data analysis techniques. A seismic excitation is generated in a first directional wellbore section in a subterranean region. The subterranean region includes fractures defined in subterranean rock. A seismic response associated with the seismic excitation is detected in a second directional wellbore section in the subterranean region. Seismic response data based on the seismic response are analyzed to identify spatial variations in fracture conductivity for the subterranean rock. A reservoir model is calibrated based on the identified spatial variations in fracture conductivity. In some cases, the reservoir model is calibrated in real time during production operations, and the reservoir model can be used for reservoir simulations.

Abstract: Ocular surgery may be performed by a variety of systems, processes, and techniques. In certain implementations, systems and processes for ocular surgery may include the ability to emulsify a lens in an eye using a modular hand-held system including a phacoemulsification unit detachably coupled to a pump unit and remove lens portions from the eye using suction provided by the pump unit.

Abstract: A control system includes a controller and an energy management system. The controller is onboard a vehicle that includes motors and an onboard energy storage device that powers the motors. The energy management system calculates estimated electric loads of powering the motors over one or more segments of a trip according to designated operational settings of a trip plan. The energy management system also determines a demanded amount of electric energy for powering the vehicle based on the estimated electric loads. The demanded amount of electric energy is based on a stored amount of electric energy in the onboard storage device. The energy management system communicates the demanded amount of electric energy to one or more of plural wayside stations disposed along the route so that the wayside stations have sufficient electric energy to charge the onboard energy storage device with the electric energy to meet the estimated electric loads.

The control system includes a controller coupled to the braking system, where the controller is configured to monitor the braking effort of the braking system at a braking region along the route. The controller is further configured to control the braking effort at the braking region, such that the braking effort approaches within a predetermined range of a braking effort threshold, but does not exceed the braking effort threshold. A method is also provided for controlling a braking effort of a braking system in a powered system.

The method then identifies operational parameters of the vehicle system. The operational parameters represent at least one of a current location of the vehicle system, a current terrain over which the vehicle system is currently travelling, an upcoming terrain that the vehicle system is travelling toward, a current moving speed of the vehicle system, a position of one or more controls of the vehicle system, a state of a brake of the vehicle system or an identification of one or more vehicle units in the vehicle system. The method then selects and implements a mitigating action to implement from plural different mitigating actions based on the alarm state and the one or more parameters of the vehicle.

Abstract: A video conference endpoint detects faces at associated face positions in video frames capturing a scene. The endpoint frames the video frames to a view of the scene encompassing all of the detected faces. The endpoint detects that a previously detected face is no longer detected. In response, a timeout period is started and independently of detecting faces, motion is detected across the view. It is determined if any detected motion (i) coincides with the face position of the previously detected face that is no longer detected, and (ii) occurs before the timeout period expires. If conditions (i) and (ii) are not both met, the endpoint reframes the view.

Abstract: A video conference endpoint detects faces at associated face positions in video frames capturing a scene. The endpoint frames the video frames to a view of the scene encompassing all of the detected faces. The endpoint detects that a previously detected face is no longer detected. In response, a timeout period is started and independently of detecting faces, motion is detected across the view. It is determined if any detected motion (i) coincides with the face position of the previously detected face that is no longer detected, and (ii) occurs before the timeout period expires. If conditions (i) and (ii) are met, the endpoint restarts the timeout period and repeats the independently detecting motion and the determining. Otherwise, the endpoint reframes the view to encompass the remaining detected faces.

Abstract: Systems and methods described herein relate to indicating a repair to perform on an asset based on historic data related to a repair on the asset and/or sensor data associated with the asset. An evaluate component aggregates information related an asset such as a repair performed or data from a sensor. A repair evaluation component indicates a repair to perform on the asset based on at least one of the data from the sensor or the information related to the asset. By utilizing asset-specific information and historical data, repair schedules for assets can be more accurate and thereby reducing untimely repairs.
