Abstract: Methods, systems, and apparatuses, including computer programs encoded on computer-storage media, for prioritizing test cases. Processes may include obtaining test artifacts that were generated based on testing one or more legacy versions of a software application using multiple test cases, generating a risk index based at least on the test artifacts that were generated based on testing the one or more legacy versions of the software application using the multiple test cases, and training an ensemble model that is configured to identify likely unnecessary or redundant test cases in connection with in testing an updated version of the software application, based at least on the risk index.

Abstract: Systems and methods for operating an engine that includes two throttles that are arranged in parallel to deliver air into a single intake manifold are described. In one example, a first throttle and a second throttle are opened according to a value of a variable that changes as a function of a requested engine air flow.

Abstract: A semiconductor review tool receives absolute Z-height values for the semiconductor wafer, such as a semiconductor wafer with a beveled edge. The absolute Z-height values can be determined by a semiconductor inspection tool. The semiconductor review tool reviews the semiconductor wafer within a Z-height based on the absolute Z-height values. Focus can be adjusted to within the Z-height.

Abstract: Systems and methods for operating an engine that includes two throttles that are arranged in parallel to deliver air into a single intake manifold are described. In one example, a first throttle is opened before a second throttle during a first condition and the second throttle is opened before the first throttle during a second condition. The throttles may be operated in this way to ensure even operation of the throttles.

Abstract: Systems and methods for iced road conditions and remediation are disclosed herein. A method can include determining an ambient temperature around a vehicle or a road relative to a temperature threshold, determining lateral acceleration of the vehicle due to steering input, determining a slippery condition based on the ambient temperature being below the temperature threshold and the expected lateral acceleration exceeding the measured lateral acceleration by more than a threshold, and selectively adjusting a vehicle operating parameter when the slippery condition is present.

Abstract: Methods and systems are provided for diagnostics of a gasoline particulate filter in an exhaust system after confirming that specific conditions are met including that an exhaust tuning valve is not degraded. In one example, a method may include indicating degradation of a hose coupled across a particulate filter responsive to a difference between a first differential pressure and a second differential pressure being greater than a threshold, the first differential pressure measured by a differential pressure sensor positioned in the hose responsive to a downstream exhaust tuning valve being fully open, the second differential pressure measured by the differential pressure sensor responsive to the exhaust tuning valve being fully closed.

Abstract: Methods and systems are provided for improving completion rates for engine system diagnostics for hybrid electric vehicles. In one example, a method may include in response to fueling of the engine of a hybrid electric vehicle being discontinued, establishing an air flow from an intake to an exhaust of the engine by relying on an electric motor to rotate the engine unfueled, and conducting a plurality of diagnostic monitors that rely on the air flow prior to reactivation of fueling of the engine. In this way, diagnostic monitor completion rates may be improved for hybrid electric vehicles, and fuel economy may be improved by coordinating the plurality of diagnostic monitors to be conducted during times when the engine is not fueled.
