We give a method for efficiently computing isomorphisms between towers of Artin-Schreier extensions over a finite field. We find that isomorphisms between towers of degree pn over a fixed field Fq can be computed, composed, and inverted in time essentially linear in pn. The method relies on an approximation process.

During the winter of 1975-1976, snowfall from the plumes of large natural-draft cooling towers of power plants has been observed. Snow accumulations up to 2.5 centimeters have been found on the ground at extended distances from the cooling towers, and visibility has been restricted to less than 1600 meters in the tower plume near ground level.

In this paper, two versions of an iterative loopless algorithm for the classical towers of Hanoi problem with O(1) storage complexity and O(2) time complexity are presented. Based on this algorithm the number of different moves in each of pegs with its direction is formulated. Keywords—Loopless algorithm, Binary tree, Towers of Hanoi.

We present here a study of the transverse granularity required for tagging jets detection and reconstruction over the expected pileup background, in the CMS Quartz Fibres Forward Calorimeters, HF. Background suppression and jet finding are achieved by an eta independent Et cut on single towers. Granularities in terms of Delta(x), Delta(y) towers are considered.

Over all non-prime finite fields, we construct some recursive towers of function fields with many rational places. Thus we obtain a substantial improvement on all known lower bounds for Ihara’s quantity A(`), for ` = p with p prime and n > 3 odd. A modular interpretation of the towers is given as well.
