Technology Transfer of As-Built and Preliminary Surveys Using GPS, Soft Photogrammetry, and Video Logging, 2002

This research involved two studies: one to determine the local geoid to obtain mean sea level elevation from a global positioning system (GPS) to an accuracy of ±2 cm, and the other to determine the location of roadside features such as mile posts and stop signs for safety studies, geographic information systems (GIS), and maintenance applications, from video imageries collected by a van traveling at traffic speed.

The Conservation Reserve Program in the Presence of a Working Land Alternative: Implications for Environmental Quality, Program Participation, and Income Transfer, August 2005

The United States has invested large sums of resources in multiple conservation programs for agriculture over the past century. In this paper we focus on the impacts of program interactions. Specifically, using an integrated economic and bio-physical modeling framework, we consider the impacts of the presence of working land programs on a land retirement for an important agricultural region—the Upper Mississippi River Basin (UMRB). Compared to a land retirement only program, we find that the presence of a working land program for conservation tillage results in significantly lower predicted signups for land retirement at a given rental rate. We also find that the presence of both a large working land and land retirement program can result in more environmental benefits and income transfers than a land retirement only program can achieve.

EU Enlargement and Technology Transfer to New Member States, November 2005

The European Union (EU) accomplished its biggest enlargement process in 2004 in terms of the number of countries, area, and population. This study focuses on the impact of enlargement, the resulting technology transfer on the grain sectors of the New Member States (NMS), and the consequent welfare implications. The study finds that EU enlargement has important implications for the EU and the NMS, but its impact on the world grain markets is minimal. The results show that producers in the NMS gain from accession because of higher prices, whereas consumers in most NMS face a welfare loss. Incorporating technology transfer into the accession increases the welfare gain of producers despite falling prices because of the larger supply shift. The loss of welfare for consumers in most NMS is lower in this case because of the decline in grain prices.

Guide to Dowel Load Transfer Systems for Jointed Concrete Roadway Pavements, September 2011

This guide provides a summary of the factors and design theories that should be considered when designing dowel load transfer systems for concrete pavement systems (including dowel basket design and fabrication) and presents recommendations for widespread adoption (i.e., standardization). Development of the guide was sponsored by the National Concrete Consortium with the goal of helping practitioners develop and implement dowel load transfer designs based on knowledge about current research and best practices.
