Improving the accuracy of livestock distribution estimates through spatial interpolation.
Animal distribution maps serve many purposes such as estimating transmission risk of zoonotic pathogens to both animals and humans. The reliability and usability of such maps is highly dependent on the quality of the input data. However, decisions on how to perform livestock surveys are often based on previous work without considering possible consequences. A better understanding of the impact ...
متن کاملTesting uniformity of stationary distribution
A random walk on a directed graph gives a markov chain on the vertices on the graph. An important question that arises often in the context of markov chain is whether the uniform distribution on the vertices of the graph a stationary distribution for the markov chain. Testing whether a distribution is uniform or “far” from being uniform is a well studied problem in property testing and statisti...
متن کاملSeed Distribution Uniformity of Sunflower
In this study, four different type seeders were evaluated for seed spacing, depth uniformity, and plant emergence at three forward speeds (3.6, 5.4, and 7.2 km h-1). The planter types were: no-till planter, precision vacuum planter, universal planter, and semi-automatic potato planter. The sowing uniformity of the horizontal distribution of seeds was described by using the multiple index, the m...
متن کاملAnalysis of Residential Irrigation Distribution Uniformity
Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricu...
متن کاملAccuracy of Irrigation Efficiency Estimates
Evaluation of actual irrigation system perfonnance should rely on an accurate hydrologic water balance over the area considered. In a companion paper, water uses are categorized as consumptive or noncon sumptive, and beneficial or nonbeneficial. Real perfonnance is based on water uses over a specified period of time, rather than observation of a single irrigation event (with associate potentia...
