chasing, metalwork technique used to define or refine the forms of a surface design and to bring them to the height of relief required. The metal is worked from the front by hammering with various tools that raise, depress, or push aside the metal without removing any from the surface (except when the term chasing, instead of the more appropriate term chiselling, is used to describe the ...

FIGURE 3. A 4017B LED chaser/sequencer test and demonstration circuit. In Figure 3, the 555 timer IC (IC1) is used as a variablefrequency asymmetrical squarewave generator that feeds clocking signals to the CLK input terminal of the 4017B IC (IC2). This output waveform is normally high, but briefly flips low once per cycle and drives LED5 on.

Diagram chasing is a customary proof method used in category theory and homological algebra. It involves an elementtheoretic approach to show that certain properties hold for a commutative diagram. When dealing with abelian categories for the first time, one would work using a diagrammatic approach without relying on the notion of elements. However, constantly manipulating universal ...
