For increasing user control and insight into preparing a mixed semiconductor design specification for simulation, there are provided methods responsive to commands that provide control over resolution of disciplines and partitioning of the design into analog and digital portions. Means for Solution A diphenylnaphthylamine derivative represented by the following general formula ,wherein R1 to R3 are alkyl groups, k is an integer of 0 to 3, j is an integer of 0 to 4, l is an integer of 0 to 6, and X1 and X2 are hydrocarbon groups having at least one ethylenically unsaturated bond. At least a subset of the LED light sources is free of a phosphor coating. A position sensor identifies a current position and orientation of the first heavy equipment, and a path from the current position of the first heavy equipment to the location of the target destination is calculated. At least one optimal sub-sequence of terms is identified from among the sequence of terms, with an optimal sub-sequence being one or more longest increasing sub-sequence.
