In one example, a method for controlling powertrain operation in a vehicle is provided, the powertrain having an engine and an automatic transmission, the engine having at least an electrically actuated cylinder valve. The encapsulant has a light transmittance that ranges from 7% to 28% for the blue light and has a light transmittance that ranges from 9% to 30% for the green light. The two terminal semiconductor device is adapted to have a capacitance when a voltage on the first terminal relative to the second terminal is above a threshold voltage and to have a smaller capacitance when a voltage on the first terminal relative to the second terminal is below the threshold voltage. Geometrical information representing the visual representation and the property values of each component are exported to a data file using the first program code. The invention also concerns a method for preparing said compounds and their therapeutic use.
