Abstract: Systems and methods are provided for determining and correcting air/fuel imbalance between cylinders of an internal combustion engine. A deactivation strategy is determined and implemented. An evaluation is made of whether the engine is operating with an air/fuel imbalance between cylinders. When an imbalance is identified, an alternate deactivation strategy is implemented. Based on outcomes of the alternate deactivation strategy, a source cylinder of the air/fuel imbalance is identified, and fuel flow to the source cylinder is corrected.

Abstract: A system and method of managing software license usage includes: receiving a simulation model that will be processed using two or more license-based software applications; identifying a first license key that will be used to process at least a portion of the simulation model; identifying a second license key that will be used to process at least a portion of the simulation model; and processing the simulation model using the first license key and the second license key, wherein the first license key and the second license key are not used simultaneously and the unused key remains in a shared pool of available license keys.
