By means of transmission electron microscopy (TEM) the structure of chemically ordered regions in Zr-doped Pb(Mg1/3Ta2/3)O-3 has been studied. Large coherent ordered domains were obtained by the addition of 5 mol% PbZrO3. The results obtained by convention ...
Total order broadcast and multicast (also called atomic broadcast/multicast) is an important problem in distributed systems, especially with respect to fault-tolerance. In short, the primitive ensures that messages sent to a set of processes are delivered ...

The precipitation state of the Al-Cu-Mg-Si and Al-Mg-Si alloys was investigated by TEM, EDS and HREM. In the Al-Cu-Mg-Si alloys, it has been shown that a structural phase transition exists between 3 phases: Q-Al5Cu2Mg8Si6, QC and QP. These phases, which ha ...
Arranging characters and strings in order of representation codes is not suitable for application programming. Even when character ordering is logical, the usual filing of words in dictionaries does not correspond with the mathematical lexicographic orderi ...
Message ordering is a fundamental abstraction in distributed systems. However, usual ordering guarantees are purely syntactic'', that is, message semantics'' is not taken into consideration, despite the fact that in several cases semantic information a ...
Total order multicast algorithms constitute an important class of problems in distributed systems, especially in the context of fault-tolerance. In short, the problem of total order multicast consists in sending messages to a set of processes, in such a wa ...
The increased interest in protocols that provide a total order on message delivery has led to several different definitions of total order. In this paper we investigate these different definitions and propose a hierarchy that helps to better understand the ...
Comparative Performance Analysis of Ordering Strategies in Atomic Broadcast Algorithms Xavier Defago, Andre Schiper, Peter Urban In this paper, we present the results of a comparative analysis of Atomic Broadcast algorithms. The analysis was done by using ...
Complex perovskite A(B'B'')O3 ceramics with various degrees of B-site order have been structurally and spectroscopically characterized by means of x-ray diffraction, transmission electron microscopy, and infrared reflectivity. In Ba(Fe1/2Nb1/2)O3 and Pb(Fe ...
