The adoption of intranets and extranets involve major organisational innovation. Intranets alter the flows and content of internal communications, while extranets alter communications between the firm and its clients and suppliers. The paper identifies a number of potential factors that may affect adoption. These include internal and external business drivers, the role of the CEO/owner, firms’ ...

Abstrlet--Most of the depth from image flow algorithms has to rely on either good initial guesses, or some assumptions about the object surfaces to achieve solutions that agree with the physical world. Waxman and Sinha point out that those restrictions can be relaxed if depth is computed from a relative image flow field. Since image flow determination is relatively much more difficult than norm...

We accelerate the computation of spherical harmonic transforms, using what is known as the butterfly scheme. This provides a convenient alternative to the approach taken in the second paper from this series on “Fast algorithms for spherical harmonic expansions.” The requisite precomputations become manageable when organized as a “depth-first traversal” of the program’s control-flow graph, rathe...
