Ground and air testing ofmobile FALCON free-space optical (FSO) communications terminals was performed in New Mexico by lIT Corporation, JHUIAPL and AFRL. The testing verified the operation of the terminals pointing, acquisition, tracking and data transmission for ground to ground link distances up to 36 km and air to air and air to ground link distances up to 65 km. The FALCON terminals have a nominal 2.5 gbps bidirectional data link. Packet goodput was generally 90% or better for the tests. Data will be presented on the pointing and acquisition sequence, tracking performance, received power and packet throughput. In addition, analysis of the atmospheric conditions and a comparison of actual performance to expected performance will be presented
, and others. A total of 8,245 tons were received in the 12-month period (Table 1). About 77% of the incoming material came from the Dairy Farm. The facility generated compost and amended soil primarily for campus use. A total of 5,495 tons was outgoing from the facility (Table 1), of which 2,234 tons was low quality compost or manure that was applied to cropland in spring 2010. The severe winter prevented this material from composting completely. The primary product of the facility was amended soil; approximately 2,751 tons of amended soil was generated. Amended soil is a blend of compost, soil and sand. The ISU Compost Facility continues to serve a unique and vital role in assisting ISU be "greener" and more sustainable. The staff continues to learn how to improve the management of the compost to benefit the university.
Background. The Coles Memorial Farm was given to Iowa State University College of Agriculture in 1974. The farm consists of about 285 acres in Williams Township, Hamilton County, one-half mile east of Williams, Iowa. Proceeds from the farm operations have funded a variety of research priorities including assistantship stipends and research equipment, plus research station facilities and improvements. Soils. The Coles Farm has typical-to-wet soils for the Clarion-Nicollet-Webster soils association. The overall CSR is 85.70. The farm has 41 percent Canisteo soils, 31 percent Clarion soils, 12 percent Nicollet soils, 8 percent Webster soils, 6 percent Harps soils, < 2 percent Okoboji soils, and < 2 percent Knoke soils. Most of these soils are poorly drained, heavy, wet soils that benefit from field tile drainage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
