All about that - a URI profiling tool for monitoring and preserving linked data

All About That (AAT) is a URI Profiling tool which allows users to monitor and preserve Linked Data in which they are interested. Its design is based upon the principle of adapting ideas from hypermedia link integrity in order to apply them to the Semantic Web. As the Linked Data Web expands it will become increasingly important to maintain links such that the data remains useful and therefore this tool is presented as a step towards providing this maintenance capability

Factors Affecting U.S. Trade and Shipments of Information Technology Products: Computer Equipment, Telecommunications Equipment, and Semiconductors

Despite a recent downturn, the information technology (IT) products sector experienced a tremendous expansion in trade and shipments during the last decade and became an increasingly important component of the U.S. economy. This expansion was driven by a variety of factors such as the globalization of IT production, constant technological innovation, rapid growth in worldwide consumption, and global trade liberalization. This working paper will examine these factors, providing particular attention to the computer equipment, telecommunications equipment, and semiconductor industries.International Development,

A finite element stream-aquifer model

General purpose finite element based numerical groundwater models were developed and applied to a shallow unconfined aquifer near Ames, Iowa. The models are microcomputer based continuous simulation models able to simulate both confined and unconfined aquifer systems in two or three dimensions. The programs have the ability to simulate the impact of such hydrologic variables as pumping, stream flow, infiltration and evapotranspiration on the aquifer. The models were written with a modular structure which separates the different hydrologic variables within the program for easy modification;The two dimensional model was calibrated and verified with data collected over a fifteen year period by various researchers. Data for the calibration of the three dimensional model were collected from a set of piezometers installed near a stream which recharges the aquifer
