Permutations of time and place in tuberculosis.
Tuberculosis remains a global health pandemic. The current depiction of the Mycobacterium tuberculosis life cycle proposes that airborne bacilli are inhaled and phagocytosed by alveolar macrophages, resulting in the formation of a granuloma that ruptures into the airways to reinitiate the infectious cycle. However, this widely proposed model overlooks the fact, established 100 years ago, that t...
متن کاملInverting Permutations In Place
In this thesis, we address the problem of quickly inverting the standard representation of a permutation on n elements in place. First, we present a naive algorithm to do it using O(log n) extra bits in O(n) time in the worst case. We then improve that algorithm, using a small bit vector, to use O( √ n) extra bits in O(n √ n) time. Using a different approach, we present an algorithm to do it us...
متن کاملIn-Place Random List Permutations
We give two algorithms to randomly permute a linked list of length n in place using O(n logn) time and O(logn) stack space in both the expected case and the worst case. The first algorithm uses well-known sequential random sampling, and the second uses inverted sequential random sampling. 1999 Published by Elsevier Science B.V. All rights reserved.

چکیده: نسبت به کارکرد و ماهیت دیپلماسی عمومی در جهان امروز نظریه های متعددی بیان گردیده و جایگاه آن در کنار نظریه های دیگر در محافل آکادمیک و دانشگاهی بررسی و تحلیل گردیده است. نظر به اهمیت دیپلماسی عمومی و جایگاه آن در سیاست خارجی ایران این نوشتار با تمرکز بر دیپلماسی عمومی در منطقه آسیای مرکزی تهیه و تنظیم شده است. این ضرورت از آنجا ناشی می شود که اولاً مفهوم دیپلماسی عمومی در سیاست خارجی ای...
15 صفحه اولRaising Permutations to Powers in Place
Given a permutation of n elements, stored as an array, we address the problem of replacing the permutation by its kth power. We aim to perform this operation quickly using o(n) bits of extra storage. To this end, we first present an algorithm for inverting permutations that uses O(lg2 n) additional bits and runs in O(n lgn) worst case time. This result is then generalized to the situation in wh...
