One of the main approaches for creating metadata for learn- ing resources in adaptive e-learning systems has been through the use of semantic web ontologies. This approach is limiting because it doesn’t usu- ally address a requirement for the support of annotators or the require- ment for signific...

In this paper we prove a lower bound for the maximum state complexity of Deterministic Finite Cover Automata (DFCAs) obtained from Non-deterministic Finite Automata (NFAs) of a given state complexity n, in case of a binary alphabet. We show, for binary alphabets, that the difference between maximum ...

The creation of learning resource metadata by instructors is a time consuming and error prone process. This paper outlines a broad research agenda to mitigate these issues.. The first part of this approach is to collect prescriptive metadata from various actors involved using ...

The nuclear reaction O-18 (d, 2n) F-18 and the separation of F-18 from the irradiated samples have been studied. For this reaction liquid H2O samples were irradiated with deuterons beam in the stainless steel cells cooled with water. The formed positron emiting F-18 was separated from (H2O)-O-18 by ...

Many web - based information - seeking tasks are set in a social context where other people’s knowledge and advi ce improves success in finding information. However, when tightly - knit contacts (friends, family, colleagues) are not available, information seeking becomes more difficult. Inspired b...

When searching for information, people often seek help from others. However, while people can benefit from communicating with others, they can usually satisfy their information needs, to some degree, without help. Because establishing explicit collaborations...
