The agreement problem is usually exploited to improve the fault-tolerant capability of software systems. For self-organized networks like cloud computing architectures that possess highly decentralized and self-organized natures, consensus, which is essential to solving the agreement problem, in such networks cannot be achieved in the ways for traditional… (More)
In quantum mechanics, a wavefunction contains two factors: the amplitude and the phase. Only when the probing beam is fully phase coherent, can complete information be retrieved from a particle beam based experiment. Here we use the electron beam field emitted from a noble-metal covered W(111) single-atom tip to image single-walled carbon nanotubes (SWNTs)… (More)
Cuttlebone is a natural marine cellular material possessing the exceptional mechanical properties of high compressive strength, high porosity and high permeability. This combination of properties is exceedingly desirable in biomedical applications, such as bone tissue scaffolds. In light of recent studies, which converted raw cuttlebone into hydroxyapatite… (More)
The Distributed Trigger Counting (DTC) problem is o raise an alert while the number of riggers received by the whole system reaches a pre-defined amount. There have been several algorithms proposed to solve such a problem in the literature. However, these existing algorithms are all under the assumption that here is no even regarding process moving, leaving… (More)
In this paper, we propose two new efficient indexing techniques for communication-induced checkpointing (CIC) protocols that can dynamically adjust their methods of managing sequence numbers during the execution, according to the heterogeneity extent of the underlying system.
The distributed trigger counting (DTC) problem is to raise an alert while the number of triggers received by the system reaches a pre-specified amount. Particularly, there have been several algorithms proposed to solve the DTC problem in the literature. However, these existing algorithms are all under the assumption that each node knows what kind of… (More)
