Performance prediction of checkpointing systems in the presence of failures is a well-studied research area. This paper makes three small contributions to this research area. First, we show how to apply the concept of availability from reliability theory as a useful metric for checkpointing systems. Second, we study the average availability of uniprocessor checkpointing systems, using the libck...

In response to Kobele et al. (2012), we evaluate four ways of linking the processing difficulty of sentences to the behavior of the top-down parser for Minimalist grammars developed in Stabler (2012). We investigate the predictions these four metrics make for a number of relative clause constructions, and we conclude that at this point, none of them capture the full range of attested patterns.

Weighted committee games generalize n-player simple voting games to m ≥ 3 alternatives. The committee’s aggregation rule treats votes anonymously but parties, shareholders, members of supranational organizations, etc. differ in their numbers of votes. Infinitely many vote distributions induce only finitely many distinct mappings from preference profiles to winners, i.e., non-equivalent committe...

We consider a number of notice and take-down regimes for Internet content. These differ in the incentives for removal, the legal framework for compelling action, and the speed at which material is removed. By measuring how quickly various types of content are removed, we determine that the requester’s incentives outweigh all other factors, from the penalties available, to the methods used to ob...

objective: the present study was carried out to study the relationship between sensation seeking and social skills in two groups of school age patients down-syndrome (ds) and autism disorder (ds).  methods: this is a descriptive-analytic and correlation study in which all participants were of primary school age (10 to 13 years) with down-syndrome and autism disorder of autism spectrum disorder ...

conclusion the low prevalence of the nb absence in normal fetuses in the present study is compatible with the larger size of the nb in iranian people compared to other communities. meanwhile, the reference range of the nb length in normal iranian fetuses was established so that basic data could be recorded for further studies regarding the absence or presence of the nb in screening for chromoso...
