Powering Down the Computing Infrastructure
T he amount of power used to drive the world’s computingrelated infrastructure—including PCs, servers, data centers, routers, and switches —has been growing rapidly. Complicating this situation has been the increasing amount of heat that higher-performing systems generate. In response, manufacturers have had to add cooling systems, which use still more power. The very largest computing complexe...
متن کامل4 Powering of Graphs
The above theorem implies that for an (N, d, λ)-expander, the number of neighbors of S is at least constant fraction of |S| (for |S| ≤ N/2), where the constant ε depends only on λ and is independent of the size of the graph. This implies that the diameter of G is at most O(logN) because of the following argument: Consider any two vertices s and t in G. The number of vertices within distance r o...
متن کاملPowering the porter brewery.
Before canals and railways developed as a major transport network, it was seldom profitable to transport beer inland over more than a few miles. In country towns and villages, therefore, beer would be brewed either by a small 'common' brewery that supplied a handful of pubs and private customers, or in an even smaller brew-house attached to the pub itself. Many families also brewed their own be...
متن کاملPowering the Nanoworld
‘Robot’ is a word of Czech origin and describes a machine that automatically performs complicated, often repetitive tasks – while a machine is any assemblage of parts that transmit forces, motion, and energy one to another in a predetermined manner. Although these formal definitions derive from the macroscopic world, assemblage, transmission and repetition remain key issues in the development o...
متن کاملThe Montgomery Powering Ladder
This paper gives a comprehensive analysis of Montgomery powering ladder. Initially developed for fast scalar multiplication on elliptic curves, we extend the scope of Montgomery ladder to any exponentiation in an abelian group. Computationally, the Montgomery ladder has the triple advantage of presenting a Lucas chain structure, of being parallelized, and of sharing a common operand. Furthermor...
