This paper studies Predictive Prefetching on a Wide Area Network with two levels of caching. The WAN that we refer to is the GRNET academic network in Greece. We rely on log files collected at the network’s Transparent cache (primary caching point), located at GRNET’s edge connection to the Internet. Our prefetching model bases its predictions on popularity ranking of passed requests. We presen...

Despite the central role of learning in visual recognition, it is largely unknown whether visual form learning is maintained in older age. We examined whether training improved performance in both young and older adults at two key stages of visual recognition: integration of local elements and global form discrimination. We used a shape-discrimination task (concentric vs. radial patterns) in wh...

This paper presents a way in which a lexicalised HPSG grammar can handle word order constraints in a computational parsing system, without invoking an additional layer of representation for word order, such as Reape’s Word Order Domain. The key proposal is to incorporate into lexical heads the WOC (Word Order Constraints) feature, which is used to constrain the word order of its projection. We ...

Abstract This study is an exercise in micro-scale comparison based on the semantic map approach. A constructed for meanings associated with word ‘grain’ four closely related South Mande languages: Dan Blowo, Tura, Mwan, and Wan. Although non-cognate, words show remarkable similarity their range of meanings, suggesting that newly introduced are same networks as they come to replace. Differences ...
