AB - compacta Isaac
We define a compactum X to be AB-compact if the cofinality of the character χ(x, Y ) is countable whenever x ∈ Y and Y ⊂ X. It is a natural open question if every AB-compactum is necessarily first countable. We strengthen several results from [Arhangel’skii and Buzyakova, Convergence in compacta and linear Lindelöfness, Comment. Math. Univ. Carolin. 39 (1998), no. 1, 159–166] by proving the fol...
متن کاملDistinguishing attacks on ISAAC
This paper presents two strong distinguishers for the deterministic random bit generator ISAAC, requiring 2 and 2 samples of respectively 64 and 32 bits, based on the observation that more than 2 167 initial states among the 2 192 ones induce a strongly non-uniform distribution of the bits produced at the first round of the algorithm. A previous attack on ISAAC presented at Asiacrypt’06 by Paul...
متن کاملScott processes
The Scott process of a relational structure M is the sequence of sets of formulas given by the Scott analysis of M . We present axioms for the class of Scott processes of structures in a relational vocabulary τ , and use them to give a proof of an unpublished theorem of Leo Harrington from the 1970’s, showing that a counterexample to Vaught’s Conjecture has models of cofinally many Scott ranks ...

The tools for capturing and sharing photos and videos have exploded to the point of ubiquity. Internet photo collections of popular landmarks now contain over a decade’s worth of photographs; thousands of timelapse scenes are available on video sharing websites; live cameras stream real-time videos of many scenes 24 hours a day; high-resolution images of an entire face of the earth are availabl...
متن کاملIsaac Keslassy - PhD Thesis
The function of a router is to switch arriving packets to their correct output destination. A router is built to achieve a specified capacity (the sum of the rates of its interfaces), and users expect a router to consistently achieve this capacity. However, no commercial high-speed router can guarantee today that it will achieve its full capacity for all arrival traffic patterns. This is due to...
