Blockchain adopts a chain data structure, and the characteristics of blocks that can only be added cannot deleted make total number accumulate over time, forcing resource-constrained nodes to become degraded in order alleviate increasingly severe storage pressure. Degraded store partial blocks, although improving scalability blockchain reducing redundancy will lead decrease availability. To add...

One-size-fits-all educational innovations do not work because they ignore contextual factors that determine an intervention’s efficacy in a particular local situation. Identifying variables within the intervention’s setting that represent important conditions for success and summarizing the extent to which the impact of the intervention is attenuated by variation in them can provide prospective...

Granularity as described by Hobbs [5] is a parameter of context that restricts a) the available objects and b) the categories and properties for characterizing objects. Geographic spatial granularity is mainly determined by size, and surfaces in geography as scale-dependency. Goodchild [4] points out that one main specialty of geographic attributes is scale-specificity : A region that is assign...

In this paper we show why scalability is one of the most important aspects for the evaluation of Machine Translation (MT) systems and what scalability entails in the framework of MT. We illustrate the issue of scalability by reporting about an MT solution, which has been chosen in the course of a thorough hands-on evaluation and which in the meantime has been developed from a pilot system to a ...

We spend much of our time trying to communicate with each other. Wide-spread use of the Internet has increased the number of ways and the amount we communicate with each other. For example, we may now spend many hours per day simply writing and replying to e-mails. Like normal communication, there is information that can be publicly known (or at least we do not care if someone else knows it), a...
