This study is one of three companion pieces on various policy themes emerging in distance education; the analysis is targeted to the pre-college level, but many of the themes generalize into all aspects of distributed learning. The other two studies focus on equity issues and on professional development. This piece centers on the emerging technologies and national priorities driving the

This paper contains measured data and empirical models for 5.85 GHz radio propagation path loss in and around residential areas. Three homes and two stands of trees were studied for outdoor path loss, tree loss, and house penetration loss in a narrowband measurement campaign that included 270 local area path loss measurements and over 276,000 instantaneous power measurements. The data will aid ...

This report describes an e ort to construct a National HPCC Software Exchange (NHSE). This system shows how the evolving National Information Infrastructure (NII) can be used to facilitate sharing of software and information among members of the High Performance Computing and Communications (HPCC) community. To access the system use the URL: http://www.netlib.org/nse/. Work on the National HPCC...

In this paper I detail the implementation of an extractionbased summarization system that uses sentence clustering and named entity identification as main features for the 2006 Multilingual Summarization Evaluation. I discuss some of the failings of my system, and what can be done to improve it.

The National Information Infrastructure (NII) that will evolve in the 1990's and beyond will impact many institutions of life. These include the way we learn and do science, self{caring, access to civil/information infrastructure systems & services, and management & control of manufacturing processes. The future scenario for the NII assumes wireless networks used by walkstations realizing the d...
