Technique for Painting Light Integration Boxes

We describe a method for the application of a highly reflectant, diffuse coating to the interior of light integration boxes. Simple box design considerations are presented in addition to techniques for dealing with a variety of problems which we have experienced. An analysis of the performance of a light integration box of 4 m 2 surface area is given. The overall box reflectivity is found to be...

Boxes: A Symbolic Abstract Domain of Boxes

Numeric abstract domains are widely used in program analyses. The simplest numeric domains over-approximate disjunction by an imprecise join, typically yielding path-insensitive analyses. This problem is addressed by domain refinements, such as finite powersets, which provide exact disjunction. However, developing correct and efficient disjunctive refinement is challenging. First, there must be...

Black Boxes

The non-structure theorems we have discussed in Chapter III rests usually on some freedom on finite sequences and on a kind of order. When our freedom is related to infinite sequences, and to trees, our work is sometimes harder. In particular, we may consider, for λ ≥ χ, χ regular, and φ = φ(x̄0, . . . , x̄α, . . .)α<χ in a vocabulary τ : (∗) For any I ⊆ λ we have a τ–modelMI and sequences āη (fo...
