$\mathcal R\!\raise2pt\hbox{$\varepsilon$}\!\hbox{$\mathcal L$}$: A Fault Tolerance Linguistic Structure for Distributed Applications
The embedding of fault tolerance provisions into the application layer of a programming language is a nontrivial task that has not found a satisfactory solution yet. Such a solution is very important, and the lack of a simple, coherent and effective structuring technique for fault tolerance has been termed by researchers in this field as the “software bottleneck of system development”. The aim ...
متن کاملFast Hardware Algorithm for Division in hbox 2m Based on the Extended Euclid's Algorithm With Parallelization of Modular Reductions
We propose a fast hardware algorithm for division in GF(2) based on the extended Euclid’s algorithm. The algorithm requires only one iteration to perform the operations that correspond to the ones performed in two iterations of previously reported division algorithms. Since the algorithm performs modular reductions in parallel by changing the order of execution of the operations, a circuit base...
متن کاملPacking Models for Multi-Domain Biomolecular Structures in Crystals with $unhbox voidb@x hbox {P}2_12_12_1$ Space-Group Symmetry
In the context of X-ray crystallography, the molecular replacement (MR) method is frequently used to obtain phase information for a crystallographic unit cell packed with a macromolecule of unknown conformation. This is important because an X-ray diffraction experiment on its own does not provide full structural information. The shape and symmetry of the unit cell is determined by the space gro...
متن کاملTransition from ciliary to flapping mode in a swimming mollusc: flapping flight as a bifurcation in ${\hbox{\it Re}}_\omega$
From observations of swimming of the shell-less pteropod mollusc Clione antarctica we compare swimming velocities achieved by the organism using ciliated surfaces alone with velocities achieved by the same organism using a pair of flapping wings. Flapping dominates locomotion above a swimming Reynolds number Re in the range 5–20. We test the hypothesis that Re≈ 5–20 marks the onset of ‘flapping...
متن کاملUp and Down Frequency-Conversion Properties of Eu3+ Doped Lead Fluorophosphate Nanoglass Ceramics
Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...
