Mundja is a MAC generation algorithm that has been designed for use together with a stream cipher. Mundja accumulates the message onto two independent registers: the first is a Cyclic Redundancy Checksum (CRC) that uses linear feedback; the second is a strengthened version of the SHA-256 register [5] that uses nonlinear feedback. Mundja is fast (asymptotically about 4 times the speed of HMAC-SH...

In this paper we prove a modification of Hofmann-Mislove theorem for a topological structure similar to the minusspaces of de Groot, in which the empty set “need not be open”. This will extend, in a slightly relaxed form, the validity of the classical Hofmann-Mislove theorem also to some of those spaces, whose underlying topology need not be (quasi-) sober. Date: 11. 2. 2004. Last revision: 14....

Sober and Wilson have propose a cluster of arguments for the conclusion that ‘‘natural selection is unlikely to have given us purely egoistic motives’’ and thus that psychological altruism is true. I maintain that none of these arguments is convincing. However, the most powerful of their arguments raises deep issues about what egoists and altruists are claiming and about the assumptions they ma...

We present Nonstandard Analysis by three axioms: the Extension, Transfer and Saturation Principles in the framework of the superstructure of a given innnite set. We also present several applications of this axiomatic approach to point-set topology. Some of the topological topics such as the Hewitt realcompactiication and the nonstandard characterization of the sober spaces seem to be new in the...

Sobriety is a subtle notion of completeness for topological spaces: A space is sober if it may be reconstructed from the lattice of its open subsets. The usual criterion to check sobriety involves either irreducible closed subsets or completely prime lters of open sets. This paper provides an alternative possibility, thus trying to make sobriety easier to understand. We deene the notion of obse...

We are all familiar with how computers and smartphones have transformed work productivity. now stand at a new threshold another technology that is predicted to further transform the way we work: Artificial Intelligence (AI). 
 In this article, hope take sober practical look AI from perspective of professional evaluators. examine might use it, it nature our tasks, what threats pose field, e...
