Implementation of Badhwar classification of corn/soybean segments
There are no author-identified significant results in this report
Recommended data sets, corn segments and spring wheat segments, for use in program development
The sets of Large Area Crop Inventory Experiment sites, crop year 1978, which are recommended for use in the development and evaluation of classification techniques based on LANDSAT spectral data are presented. For each site, the following exists: (1) accuracy assessment digitized ground truth; (2) a minimum of 5 percent of the scene ground truth identified as corn or spring wheat; and (3) at least four acquisitions of acceptable data quality during the growing season of the crop of interest. The recommended data sets consist of 41 corn/soybean sites and 17 spring wheat sites
AgRISTARS: Supporting research. Classification of corn: Badhwar profile similarity technique
The same software programs used to classify spring wheat are applied to the classification of corn in 26 segments in the corn belt. Numerical results of the acreage estimation are given. Potential problem areas defined in an earlier application are examined
Classification of wheat: Badhwar profile similarity technique
The Badwar profile similarity classification technique used successfully for classification of corn was applied to spring wheat classifications. The software programs and the procedures used to generate full-scene classifications are presented, and numerical results of the acreage estimations are given
Fish or Cut Bait? Dwight D. Eisenhower and the Creation of the St. Lawrence Seaway
“Our relations with Canada, happily always close, involve more and more the unbreakable ties of strategic interdependence. Both nations now need the St. Lawrence Seaway for security as well as for economic reasons. I urge the Congress promptly to approve our participation and construction.” When President Dwight D. Eisenhower included these sentences in his State of the Union Address in January of 1954, there must have been an almost audible sigh of relief from the thousands of Seaway activists, Congressmen, and lobbyists across the country. The previous year had not been an easy one for supporters of the St. Lawrence Seaway project, but now in 1954 they had the guaranteed support of the most powerful and popular man in the nation
The Unsung Vigilance: A History of Sentinel
At risk of over using a popular cliché, there are objects everywhere on the Gettysburg College campus that are “hidden in plain sight.” For some objects, it is easy to stay hidden in this manner. Though we as college students and faculty pass them each day, they are simple plaques embedded in the cement paths we walk on, or the porticos of the academic buildings we enter without even thinking. Yet for other objects, it remains a perpetual mystery as to how even the infamously dense mind of the modern young adult could fail to, at least notice. The sculpture Sentinel, the massive conglomeration of stone and mortar standing 10 feet tall, is one such object. The plaque that is embedded in the ground at the foot of this monstrosity provides only vague enlightenment. [excerpt]

Hidden in Plain Sight is a collection of student papers on objects that are hidden in plain sight around the Gettysburg College campus. Topics range from the Glatfelter Hall gargoyles to the statue of Eisenhower and from historical markers to athletic accomplishments.

Compton scatter attenuation gamma ray spectrometer
A gamma ray spectrometer is described for use in intense radiation fields such as those in the vicinity of a rocket engine exhaust. A collimated radiation beam is Compton scattered toward shielded spectrometers to reduce the energy and intensity of the radiation and is energy selective among the spectrometers. The scattering targets are changeable to control the percentage of the radiation scattered. Sum-Compton coincidence techniques are employed for data selection
