Spatial And Temporal Variations Of Cloud-To-Ground Lightning In Southern Michigan, Michael A. Crimmins

Masters Theses

Lightning has a profound impact on many aspects of modern day society. Understanding its temporal and spatial distributions is fundamental in learning to coexist with its destructive power. This study surveyed the spatial and temporal distribution of cloud-to-ground lightning over southern Michigan using data provided by the Detroit Edison Company. Flash density and 'lightning day' maps were produced for every year of the 1985 to 1995 study period and then averaged to determine long term trends. A temporal analysis determined the distribution of lightning from the inter-annual down to the diurnal scale.

The spatial analysis indicates both deficiencies in the …

Spatial And Ethnic Patterns Of Real Estate Control Affecting Upward Mobility Of Immigrants In A Nineteenth Century Industrial Community, Debra S. Alfonso

Masters Theses

The subject of immigrant success has previously been analyzed in the context of ethnic characteristics, individual heroism, worker solidarity, and advancement of industrialization. Most immigrants start at the bottom of the social-economic ladder. The mechanisms of advancement vary depending on both ethnic values and the constraints of the socioeconomic system. The key variable is normally thought to be advancing occupational status.

The problem addressed is how did recent immigrants to a 19th century steel-town obtain home ownership and advancement in spite of declining industrial wages. Using a GIS system to link and analyze geographic and historical records I was able …

Manipulation Of High Spatial Resolution Aircraft Remote Sensing Data For Use In Site-Specific Farming, Gabriel B. Senay, Andrew D. Ward, John G. Lyon, Norman R. Fausey, Sue E. Nokes

Biosystems and Agricultural Engineering Faculty Publications

Three spatial data sets consisting of high spatial resolution (1 m) remote sensing images acquired in 12 spectral bands, an on-the-go yield map, and a Digital Elevation Model were co-registered and evaluated for spatial variability studies in a Geographic Information Systems environment. Separate on-the-go yield maps were developed for 3, 5, and 12 statistically significant mean yield classes. For each yield class, the corresponding mean spectral and elevation data were extracted. The relationship between mean spectral and yield data was strongly linear (r = 0.99). Also, a strong linear relationship between mean yield and elevation data (r = 0.92) was …
