Pearson, William Andrews
The evolution of drones has drastically changed since their military beginnings. Through the technological advances of drones, they are now able to assist in a plethora of areas including agriculture. Precision agriculture involves using information from sensors within agricultural fields and using this to make the farm and labor more efficient. The present research dives into understanding variations in crop fields and the differences in crops through the use of drone mapping. The main question at hand involves examining if differences in elevation of a corn field with water runoff resulted in the crop variations. The methodology of this research involves the use of a Phantom drone, with the software DroneDeploy, for gathering samples and determining the results of variations in the corn crops. Corn fields on the Fresno State University campus were the source of sampling. A Veris machine was utilized in order to collect soil samples at GPS located spots where variations occurred. Through the maps created by DroneDeploy there were differences in elevation found where corn crops varied. This finding illustrates how elevation and gravity can affect nutrients and water being allowed to different areas in the soil. Through this research, further studies of agricultural fields can be done with drones enabling farmers to look at variations in their fields, sample the inflicted areas, and understanding the implications of variations. This method can reduce labor hours and expenses as well as enhance the time efficiency for farmers and their product.

Souza, Tony M.
The general overuse of milking machine teat cups has been an enigma with most dairymen. No conducive information has been available upon which to base inflation usage other than manufacturers recommendations coupled with personal experiences. In addition, inflation pressure will vary because of the type of milking equipment used (ex: DeLaval, Surge, or Bou-Matic). Many dairymen have demonstrated that work is needed in this area to show at what point the inflation loses its optimal efficiency. The specific level of inflation-efficiency needs to be established using both the single shot and the double-shot pulsator. Considerable effort has been directed toward creating the best inflation to use; the narrow bore or a wide bore inflation have both been explored. A narrow bore liner is now well recommended over the wide bore inflation. the question is, hog long can the narrow bore inflation of various types be used to their fullest efficiency? Efficiency is generally evaluated by the number of cow-milkings that the inflation device optimally uses. This study was designed to statistically evaluate the narrow bore, ring-type stretch inflation (commonly known as the 01 inflation) as well as the narrow bore, molded one piece inflation (commonly known as the 01 inflation). The study described here with evaluates the liners within the device at various milking intervals. Also, they are to be compared one with the other. This will be accomplished with the use of a single-shot pulsator and repeated with the double-shot pulsator. Much of the milking equipment today is developed and tested in parts of the world where cow3 are not subject to as much stress as they are in California. Increased milk production per cow, as well as pronounced differences in weather conditions, demand much of the milking equipment used in California.
