The analysis of large-scale software is difficult in the absence of supporting tools, due to the sheer size and complexity of today’s systems. We present CODECITY, a language-independent interactive 3D visualization tool for the analysis of large object-oriented software systems. Using a city metaphor, it depicts classes as buildings and packages as districts of a “software city”. We start pres...

A few readers of my last two columns may have suspected that something was afoot. Why, they might ask, does he suddenly produce not one, but two confessions? After shamefacedly exposing his tendency to consider book theft as a way of acquiring knowledge and trying to reverse the hint of plagiarism in his works by suggesting that it was the other way around, we might expect anything. Well, the e...

Mechanosensation in an adipose fin.

Adipose fins are found on approximately 20% of ray-finned fish species. The apparently rudimentary anatomy of adipose fins inspired a longstanding hypothesis that these fins are vestigial and lack function. However, adipose fins have evolved repeatedly within Teleostei, suggesting adaptive function. Recently, adipose fins were proposed to function as mechanosensors, detecting fluid flow anterio...

Determining whether a propositional theory is satisfiable is a prototypical example of an NPcomplete problem. Further, a large number of problems that occur in knowledge representation, learning, planning, and other areas of AI are essentially satisfiability problems. This paper reports on a series of experiments to determine the location of the crossu2rer point the point at which half the rand...
