Abstract: Certain aspects of the present disclosure provide techniques for performing surgical ophthalmic procedures, such as cataract surgeries. An example method of determining one or more intraocular lens (IOL) parameters for an IOL to be used in a cataract surgery procedure includes generating, using a fused machine learning model, recommendations including one or more IOL parameters for the IOL to be used in the cataract surgery based, at least in part, on first predicted lens behavior for each of one or more IOLs by an emulated finite element analysis (EFEA) model and the second predicted lens behavior for each of the one or more IOLs by an IOL power calculator (IPC) machine learning model.

Abstract: A collapsible flap deployment system for an aircraft wing that includes a support beam pivotably connected to a carrier beam, which is connected to a wing flap. A rear spar fitting is connected to a wing rear spar by a first plurality of fasteners and a second plurality of fasteners connects the support beam to the rear spar fitting.

An impact load to the bottom of the support beam puts the link into compression applying a force to the fuse pin until the fuse pin shears releasing the link from the rear spar fitting. The impact load rotates the support beam and carrier beam causing the second plurality of fasteners to fail releasing the support beam and carrier beam from the wing rear spar.

Abstract: Embodiments provide techniques for testing a plurality of variations of a user experience, where each of the plurality of variations is distinct from other variations in the plurality of variations. For each permutation of a plurality of stratification factors that characterize users of the online site, embodiments generate a respective set of pseudorandom numbers. Additionally, user requests are assigned to variations in the plurality of variations, based on the generated sets of pseudorandom numbers. Embodiments also track user retention information relating to the user requests. At least one of the plurality of variations is rated, based on the user retention information.
