In the paper we extend known results studying the application of CAs for stream ciphers. We illustrate the notion of weak keys in such a cryptosystem and describe the experiments related to its implementation on micro-controllers.

In this paper, we introduce a new class of local consistencies, called f -consistencies, for qualitative constraint networks. Each consistency of this class is based on weak composition ( ) and a mapping f that provides a covering for each relation. We study the connections existing between some properties of mappings f and the relative inference strength of f -consistencies. The consistency ob...

The phase transition between solid and liquid in an undercooled liquid leads to dendritic growth of the solid phase. The problem is modelled by the Stefan problem with a modiied Gibbs-Thomson law, which includes the anisotropic mean curvature corresponding to a surface energy that depends on the direction of the interface normal. A nite element method for discretization of the Stefan problem is...

The MAC and ASP searches for events with a single photon and no other observed particles are reviewed. New results on the number of neutrino generations and limits on selectron, photino, squark and gluino masses from the ASP experiment are presented. Presented at the SLAC Summer Institute on Particle Physics Stanford, California, July 29 August 9, 1985 * Work supported by the Department of Ener...

In this paper we present two Douglas–Rachford inspired iteration schemes which can be applied directly to N-set convex feasibility problems in Hilbert space. Our main results are weak convergence of the methods to a point whose nearest point projections onto each of the N sets coincide. For affine subspaces, convergence is in norm. Initial results from numerical experiments, comparing our metho...

In typical applications, a priority queue is used to execute a sequence of n insert , m decrease, and n delete-min operations, starting with an empty structure. We study the performance of different priority queues for this type of operation sequences both theoretically and experimentally. In particular, we focus on weak heaps, weak queues, and their relaxed variants. We prove that for relaxed ...

I start by reviewing existing ~ pp measurements with particular emphasis on the recent 221 MeV ~pp measurement at TRIUMF which permitted the weak meson-nucleon coupling constants h ρ and h pp ω to be determined separately for the first time. I then review ~np experiments, with specific details of the ~np → dγ experiment now under preparation at Los Alamos National Laboratory. This experiment wi...
