A linear on-line algorithm for computing a shortest subsequence that distinguishes two different bit-strings is presented. The method is based on a special way of factorizing strings.
The speed of a chain is subject to periodic fluctuations, even for a constant speed of the driving sprocket, due to the fact that a chain lying on a sprocket forms a polygon rather than a circle. It is shown that the dynamic loading of the chain due to this “polygonal action” is similar to that of a simple forced vibration where, beyond a certain critical speed, higher speeds produce lower dynamic loads.
Birds during normal sustained flight must be able to dissipate more than 8 times as much heat as during rest in order not to be overheated. The Nike Free Run 3 Footlocker Canada
experiments reported in this note on the hemoglobin systems from two different birds indicate the existence of a molecular mechanism by which hemoglobin is used simultaneously for oxygen transport and heat dissipation.
Let H be a graph with κ1 components and κ2 blocks, and let G be a minor-minimal 2-connected graph having H Nike Free 3.0 Womens as a minor. This paper proves that |E(G)|−|E(H)|⩽α(κ1−1)+β(κ2−1) for all (α,β) such that α+β⩾5,2α+5β⩾20, and β⩾3. Moreover, if one of the last three inequalities fails, then there are graphs G and H for which the first inequality fails.
