Abstract: Techniques are described herein that are capable of constructing a finite automaton using regular expression derivatives to simulate behavior of a backtracking engine. The behavior indicates an order in which paths in an input regular expression are to be evaluated by the backtracking engine. The finite automaton is constructed to include a graph that includes a root node that represents the input regular expression. Regular expressions are derived such that each derived regular expression is a regular expression derivative of the input regular expression or of another derived regular expression. Priorities are assigned to alternations in the derived regular expressions to correspond to priorities indicated by the behavior. Nodes that represent the respective derived regular expressions and transitions between respective pairs of nodes are caused to be included in the graph. Priorities, which correspond to the order, are assigned to respective branches of the graph.

Abstract: A water-based acrylic latex paint has a dispersant-over-pigment (DOP) ratio between 0.5 and 1.5 to form a coating in which the pigment has a low concentration and is highly dispersed throughout to absorb in the visible band to produce a color (e.g., black) and is transmissive in the NIR and SWIR bands. The variables that determine absorption in the visible band and transmission in the NIR and SWIR bands include the DOP ratio, a pigment weight percentage between 1-2% in the paint and a coating thickness between 2 and 4 mil. To control the viscosity, the dispersing agent is suitably an acrylate-based block co-polymer, of molecular weight above 2,000 grams per mole, that includes an amine-functional block to anchor onto the pigment.
