DES formed the basis of the first automated teller machine (ATM) personal identification number (PIN) code authentication and until recent years existed as the primary authentication encryption method for UNIX machines. DES is a block cipher using a 64-bit block size with a 56-bit key length....
so an adversary who can issue commands to a powered-on machine may bypass disk encryption. File encryption only permits access on a per-file basis, and so is better suited to protect particular files of interest from being read even if the adversary has access to the machine. But the logis...

Kuperberg [11] proved that this inequality remains true if one drops the condition of central symmetry. The reader interested in a more comprehensive account of the theory of packing and covering is referred to the survey papers of G. Fejes Tóth and W. Kuperberg [5,6] and to the book ...
important point to monitor the improvement of the RG predictions of the critical exponents. With that in mind, our aim in this work is to first obtain theε-series corresponding to the recent seven-loop coupling series for theβ,γm2andγϕrenormalization group functions and then apply our ...
Graph Theory 1982, North-Holland Mathematics StudiesRalph Tindell 3 Point-Symmetric Graphs A graph G is point-symmetric if for any pair u, v of points of G there is an automorphism ϕ of G with ϕ(u) = v. We now define and establish the point-symmetry of a class of graphs called...
In particular, the grid can be constructed including the metric elements up to machine precision. We choose the grid spacing such that the separatrix (ψp=0) is reasonably discretized in the sense that grid cells are close to being quadratic. However, this choice leads to a poloidal over-...

Due to its expensive computational cost, further improvements have been made only for Cartesian cells using pre-computed values to find the reconstructed centroid in an efficient manner [25] and even a machine learning approach [26] improving drastically the runtime. When large deformations of the...
