Modeling Migration Effects on Agricultural Lands: A Growth Equilibrium Model

We estimate a system-of-equations model designed to measure the interaction between intertemporal patterns of changes in population, employment, and agricultural land densities. The model is applied to West Virginia for the 1990-1999 period. Consistent with recent findings on migration patterns, the results show that jobs followed people. New jobs were captured by commuters, while agricultural land losses were occurring in the commuters' counties of origin or bedroom communities. However, counties with relatively more profitable and concentrated agricultural enterprises were less susceptible to alternative land use pressure than counties with less productive or fragmented agricultural land. Elasticities indicate population change is elastic, whereas employment and agricultural land density changes are inelastic to factors affecting them. Growth management, when combined with agricultural land retention programs, may be most effective at preserving agricultural land in high growth or potential growth areas.Land Economics/Use,

NONMARKET VALUE OF WESTERN VALLEY RANCHLAND USING CONTINGENT VALUATION

With the irreversible loss of agricultural land to develop uses in certain areas, there is increased concern that land be preserved for posterity'Â’s sake. We estimate the nonmarket value of a ranchland protection program in the Yampa River Valley in Routt County, Colorado, including the Steamboat Springs resort. The case study builds on previous land preservation studies by adding several preferences indicators. We find that local residentsÂ’' willingness to pay is substantial, but insufficient, to justify protecting the existing quantity of valley ranchland in the study area.Land Economics/Use,

Multispectral Image Correction for Geometric Measurements

Multispectral- and hyperspectral imaging technologies enable new possibilities in industrial measurement applications. Based on the knowledge of remote sensing a lot of investigations were made in the last decades of years. Nevertheless the demands on remote sensing versus technical multi spectral image processing are quite different. In the field of precise geometric measurement technics it is necessary to correct the image data between different spectral channels with a high accuracy, normally in the micron range. Otherwise the geometric absolute value of fail detection on edges can be become very large. State of the art in industrial imaging and detection of geometric features is the calibration of only one imaging channel. In this paper, the studies on a twelve channel multi spectral imager were presented. For the applied filter wheel system, investigations on the improvement of lens aberration as well as for the defocus problem were made. Therefore a calibrated high precision geometric test chart was used to calibrate the system geometrically. To correct the geometric errors on the image plane a special moving filter approach, based on linear convolution, was developed. For every channel a calibration matrix were calculated and applied on the image system output

On Lyndon's equation in some Λ-free groups and HNN extensions

In this paper we study Lyndon's equation xpyqzr = 1, with x, y, z group elements and p, q, r positive integers, in HNN extensions of free and fully residually free groups, and draw some conclusions about its behavior in Λ-free group
