Quiescent Reliable Communication and Quiescent Consensus in Partitionable Networks
We consider partitionable networks with process crashes and lossy links, and focus on the problems of reliable communication and consensus for such networks. For both problems we seek algorithms that are quiescent, i.e., algorithms that eventually stop sending messages. We first tackle the problem of reliable communication for partitionable networks by extending the results of [ACT97a]. In part...
متن کاملPhase-Destabilization Mechanism of Polymer-Modified Bitumens in Quiescent Annealing
Bitumen as a binder in coating and insulating materials is modified with polymers to improve its performance in service conditions. Almost all polymers are incompatible with bitumen, and at high temperatures due to relatively very low viscosity of the bitumen phase, are separated from it. These lead to a considerable limitation in the use and handling of polymer-modified bitumens. An understand...
متن کاملBetween Linearizability and Quiescent Consistency - Quantitative Quiescent Consistency
Linearizability is the de facto correctness criterion for concurrent data structures. Unfortunately, linearizability imposes a performance penalty which scales linearly in the number of contending threads. Quiescent consistency is an alternative criterion which guarantees that a concurrent data structure behaves correctly when accessed sequentially. Yet quiescent consistency says very little ab...
متن کاملSerological Monitoring of Avian Influenza in Migratory Birds of Iran
Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
متن کاملIsolation of Chlamydophila psittaci from pet birds in Iran
Avian chlamydiosis is one of the most important infectious diseases of birds. Despite the rapid growth of exotic bird populations in Iran, there is little or no information on the specific infections that these types of birds carry. In this study, conventional isolation methods were used in cell culture to study occurrence of infection in pet birds. Samples from the conjunctiva, choana, and clo...
