Pulse Code Modulation (PCM) data storage and analysis using a microcomputer

The current widespread use of microcomputers has led to the creation of some very low-cost instrumentation. A Pulse Code Modulation (PCM) storage device/data analyzer -- a peripheral plug-in board especially constructed to enable a personal computer to store and analyze data from a PCM source -- was designed and built for use on the NASA Sounding Rocket Program for PMC encoder configuration and testing. This board and custom-written software turns a computer into a snapshot PCM decommutator which will accept and store many hundreds or thousands of PCM telemetry data frames, then sift through them repeatedly. These data can be converted to any number base and displayed, examined for any bit dropouts or changes (in particular, words or frames), graphically plotted, or statistically analyzed

Herbicide Application Rates: Risk Premiums with Environmental Implications

This paper examines the role of risk aversion in setting herbicide label rates and application rates. Companies establish label rates to be efficacious for a wide range of conditions. The use of reduced rates of herbicide offer the opportunity to increase farm profit and reduce herbicide use, an environmental benefit.Crop Production/Industries, Environmental Economics and Policy, Risk and Uncertainty,

Water Quality Trends across Select 319 Monitoring Sites in Northwest Arkansas

Northwest Arkansas contains two 319 priority watersheds that the Arkansas Natural Resources Commission has identified as being impacted by point source and nonpoint source pollution (i.e., phosphorus, nitrogen, and sediment). This project specifically focused on determining water quality trends at select sites within the Illinois River (HUC# 11110103) and Beaver Reservoir (HUC# 11010001) priority watersheds, including Ballard Creek, Osage Creek, Illinois River, White River, West Fork White River and the Kings River where sufficient constituent data were available. Water quality trends were analyzed using flow‐adjusted constituent concentrations of phosphorus, nitrogen, sediment, sulfate and chloride, and parametric and non‐parametric statistical techniques to determine if constituent concentrations were increasing, decreasing or not significantly changing over time. Overall, flow‐adjusted concentrations of phosphorus and sediment have been decreasing across these watersheds based upon both statistical approaches. The decrease in phosphorus was likely the most important observation, because most water quality concerns in this region have focused on elevated phosphorus concentrations in these transboundary watersheds. These trends can be used along with other watershed information to improve the knowledge of how past, current, and future management decisions have influenced the watershed

Substitutability of Livestock Manure for Chemical Fertilizer: A Contingent Valuation Analysis of Crop Producers

The impact of new manure management regulations depends on the willingness of crop producers to accept manure. A contingent valuation analysis of crop producers was used to estimate the willingness of crop producers to accept or pay for manure. Results indicate that producers will pay a positive price on average, but some would require a payment before accepting manure.Farm Management,

Manure Application Rules and Environmental Considerations

Three manure application limits (N Limit, Annual P Limit and P Banking) were modeled with particular attention to the number of hours needed to appropriately distribute manure. The benefit and costs estimates indicated that P Banking was more profitable than N Limit which was more profitable than Annual P Limit. The number of hours required indicated that the Annual P Limit would not be completed within a two month window approximately 2 of 10 years. The increased number of hours for the Annual P Limit also increased the probability of a runoff event following manure application, relative to the other two scenarios. This work indicates that regulations that require Annual P Limits of manure cost the farmer and may have the unintended consequence of increasing runoff.manure, environment, policy, runoff, hours, acres, probability, rainfall, Environmental Economics and Policy, Farm Management, Livestock Production/Industries, Production Economics, Risk and Uncertainty,

Factors that affect the price of manure as a fertilizer (2008)

This paper acts as a guide to the presentation titled "Value of Manure as a Fertilizer."An often asked question is "what is the price of manure?" This question is difficult to answer because price is determined by markets. In the absence of markets for manure, its price is unknown. The best that can be done is to estimate the potential price of manure for a specific purpose

SWINE BREEDING SYSTEMS: A STOCHASTIC EVALUATION WITH IMPLICATIONS FOR EMERGING TECHNOLOGY

The after-tax net present value for 27 swine breeding systems composed of Duroc, Hampshire, and Yorkshire breeds were simulated and ordered using stochastic dominance analysis. The concept of the value of information was expanded to develop the concept of the willingness to pay to adopt a new technology. For producers not currently using the dominant system, estimates of the allowable present value cost of adoption are reported and used to explain diverse production practices.Research and Development/Tech Change/Emerging Technologies,

An empirical test of the information processing and socio-political perspectives in new product development projects

New product development research draws on a range of different theories, though no overarching theory explaining NPD success has emerged. Atuahene-Gima and Evangelista (2000) however identified an underlying dichotomy in existing theories: economically rational approaches, and socio-political approaches. In this paper we test a model which reflects this dichotomy, and using data from 184 NPD projects, we provide empirical evidence that that this multi-lens theoretical approach has great potential to better understand factors driving NPD outcomes
