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...
متن کاملBlack Boxes, Incorporated
The term “Black Box” often refers to a device whose functionality we understand, but whose inner workings we don’t, or choose to ignore. This term appears a lot in a large variety of contexts within theoretical computer science, and happens to be extremely convenient to capture computations with restricted knowledge about or access to certain information. In its most basic form, a black box (al...
متن کاملWindows on Black Boxes ?
This paper provides an overview of the survey-based literature on industrial Research and Development (R&D) laboratories, beginning with the work of Edwin Mansfield. Topics covered include R&D projects, new products, and new processes; the appropriability of intellectual property; the limits of the firm in R&D; and spillovers of knowledge from other firms and universities into the laboratories....
متن کاملVerifying Designs Containing Black Boxes
We deene a notion of equivalence for designs containing black boxes. This notion is applicable to both gate-level designs, as well as designs operating on integer variables. Using this notion, we describe a sound and complete methodology for optimizing designs containing black boxes, i.e. components whose functionality is not known; these arise naturally in the course of hierarchical design.
متن کاملProjecting uncertainty through black boxes
Computational models whose internal details are not accessible to the analyst are called black boxes. They arise because of security restrictions or because of the loss of the source code for legacy software programs. Computational models whose internal details are extremely complex are also sometimes treated as black boxes. It is often important to assess the uncertainty that should be ascribe...
