Biomass Estimation Using Statistical And Neural Network Analysis Of Aster Data, Vijay O. Lulla

All-Inclusive List of Electronic Theses and Dissertations

This study assessed the performance of different biomass estimation methods using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) lll data in a temperate forest. Multiple linear regression statistics of spectral band data and derived indices with biomass values were compared with advanced neural network models created with spectral band data and indices to model biomass values. Biomass for the study area was estimated using both of these methods and the results were discussed. The data were analyzed using multivariate statistical analysis. Correlation analysis and regression analysis were employed to understand the relationship of biomass to the spectral data and …

Paper Substrates For Electronic Printing, Laura K. Wood

Masters Theses

Printed Radio Frequency Identification (RFID) labels utilize conductive inks to provide the means for wireless flow of electronic signals. An RFID label is an identification label with an integrated circuit and antenna that transmits data via radio waves to a reader, which sends the data to a computer for processing. RFID labels allow manufacturers and retailers to accurately track their inventory more efficiently than previously possible with bar codes. However, etched metal RFID labels are too expensive for widespread implementation. The key to reducing the cost of RFID technology is replacing etched metal tags with tags printed with conducting ink. …

Picture This, Gary Bentrup, Gary Wells

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Despite the use of planting plans and engineering drawings. Many landowners find it difficult to conceptualize what a future conservation practice or system will actually look like on their landscape. This lack of understanding can create challenging barriers in the planning process and is exacerbated by the long-term commitment that many conservation systems require from landowners. Landowners often lament if they could only see a picture of the proposed action on their property, then they could make a decision. Fortunately, natural resource professionals have a tool called visual simulations to help address this dilemma.

The Influence Of Hurricane Winds On Caribbean Dry Forest Structure And Nutrient Pools, Skip Van Bloem, Peter G. Murphy, Ariel E. Lugo, Rebecca Ostertag, Maria Riovera Costa, Ivelisse Ruiz Bernard, Sandra Molina Colon, Miguel Canals Mora

Publications

In 1998, we measured the effects of Hurricane Georges after it passed over long-term research sites in Puerto Rican dry forest. Our primary objectives were to quantify hurricane effects on forest structure, to compare effects in a large tract of forest versus a series of nearby forest fragments, to evaluate short-term response to hurricane disturbance in terms of mortality and sprouting, and to assess the ability of hurricanes to maintain forest structure. We sampled damage from 33 plots (1.3 ha) across a 3000-ha tract of forest as well as in 19 fragments. For stems with 2.5-cm minimum diameter, 1004 stems/ha …

Multi-Source Image Classification, Hillary Tribby, James Kroll, Daniel Unger, I-Kuai Hung, Hans Michael Williams

Faculty Presentations

Since multi-source image classifications have the ability to exceed single source processes, such as traditional unsupervised classification methods, this paper will present the integration of four types of data: Lidar, elevation, multispectral and thermal. Using multi-source data and maximum likelihood classification methodology, as well as all possible permutations of data types, this paper will discuss ways to increase accuracy assessments of forested areas in east Texas and find the best combination of data sources.

Analyses Of High Resolution Hyperspectral Imagery For Characterization Of Ponderosa Pine Woodlands, Cullen R. Robbins

School of Natural Resources: Dissertations, Theses, and Student Research

The Bessey Unit of the Nebraska National Forest is a planted ponderosa pine forest located in the Nebraska Sand Hills. Planted in the early 20th Century, it provides a unique opportunity to study the effects of ponderosa pine establishment on the surrounding grassland ecosystem and the effects of increasing pine density on the forest ecosystem. It has been hypothesized that there are key levels of canopy cover at which shifts in ecosystem function occur. The goal of this research was to use remotely sensed data to develop a reliable method for estimating canopy cover. More specifically, canopy cover was estimated …

Street Trees In The Urban Forest Canopy: Portland, Oregon, Joseph Poracsky, David Banis

Geography Faculty Publications and Presentations

Attempts to identify the contribution of street trees to the overall urban forest of a city have been rare and lack consensus on how to measure that contribution – percentage of trees, percentage of canopy cover, or percentage of leaf area. The actual numeric values presented in the literature also vary over a broad range and often are based on estimates, extrapolations from aggregated data, or simply stated with no empirical data referenced. This study was undertaken to evaluate the contribution of street trees to canopy in Portland, Oregon. The study involved both visual and digital analysis of multi-band aerial …

Use Of Borate In Semi-Chemical Pulping, Promodh K. Veguru

Masters Theses

The original Neutral Sulfite Semi-Chemical (NSSC) pulping process used sodium sulfite as the principle cooking chemical and had the disadvantage of sulfur emission problems. Considerable research was conducted to investigate the use of other chemicals including sodium hydroxide, but was not completely satisfactory. Several mills adapted a sodium carbonate based process but experienced slower pulping and reduced physical properties. The objective of this research is to study the use of borate as a pulping chemical in sodium carbonate semi-chemical pulping. The experimental plan included digester cooks; controls with pure sodium carbonate, and the other with partially borate autocausticized sodium carbonate. …

Spatial-Temporal Population Dynamics Across Species Range: From Centre To Margin, Qinfeng Guo, Mark Taper, Michele M. Schoeneberger, James R. Brandle

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Understanding the boundaries of species’ ranges and the variations in population dynamics from the centre to margin of a species’ range is critical. This study simulated spatial-temporal patterns of birth and death rates and migration across a species’ range in different seasons. Our results demonstrated the importance of dispersal and migration in altering birth and death rates, balancing source and sink habitats, and governing expansion or contraction of species’ ranges in changing environments. We also showed that the multiple equilibria of metapopulations across a species’ range could be easily broken following climatic changes or physical disturbances either local or regional. …

Flow Pathways And Sediment Trapping In A Field-Scale Vegetative Filter, Matthew J. Helmers, Dean E. Eisenhauer, Mike Dosskey, Thomas G. Franti, Jason M. Brothers, Mary Carla Mccullough

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Vegetative filters (VF) are a best management practice installed in many areas to control sediment movement to water bodies. It is commonly assumed that runoff proceeds perpendicularly across a VF as sheet flow. However, there is little research information on natural pathways of water movement and performance of field-scale VF. The objectives of this study were: (1) to quantify the performance of a VF where the flow path is not controlled by artificial borders and flow path lengths are field-scale, and (2) to develop methods to detect and quantify overland flow convergence and divergence in a VF. Our hypothesis is …

Synthesis Of Design Guidelines And Experimental Data For Water Quality Function In Agricultural Landscapes In The Intermountain West, Susan Buffler, Craig Johnson, John Nicholson, Nancy Mesner

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Currently, there is no scientific literature examining appropriate riparian buffer widths for water quality for streams on private agriculturally dominated lands in arid regions of the Intermountain West. The initial step in this research effort was a review of buffer research as documented in the literature in other physiographic regions of the United States. Research findings on appropriate buffer widths for water quality parameters were synthesized using a matrix format. Differences between arid and non-arid landscape characteristics, soil, topography, vegetation, climate and hydrology and their effect on buffers for water quality were also researched. The combined research findings in this …

Structure And Development Of Pitch Canker Infected Monterey Pine Stands At Año Nuevo, California, Douglas D. Piirto, Sauli Valkonen

Natural Resources Management and Environmental Sciences

The sustainability of indigenous Monterey pine (Pinus radiata D. Don)at Ano Nuevo stands in the central coast of California was examined. The foremost management objective in these stands is to establish and maintain stand structures that ensure a sustainable presence of the species in terms of uneven-aged management. The major threats are the proliferation of shade-tolerant tree species and the pitch canker ( Fusarium circinatum) disease. The study was based on data from 17 systematically placed sample plots, measured once, in one stand with a very high degree of variation in stand structure and species composition. The results …

Modeling Water And Sediment Trapping By Vegetated Filters Using Vfsmod: Comparing Methods For Estimating Infiltration Parameters, Amanda Fox, Dean E. Eisenhauer, Mike Dosskey

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Vegetated filters (buffers) are used to intercept overland runoff and reduce sediment and other contaminant loads to streams (Dosskey, 2001). Filters function by reducing runoff velocity and volume, thus enhancing sedimentation and infiltration. lnfiltration is the main mechanism for soluble contaminant removal, but it also plays a role in suspended particle removal. By decreasing the discharge and velocity of overland flow, infiltration causes a decrease in sediment transport capacity, and thus sedimentation is enhanced.

Although the impact of infiltration on soluble and suspended contaminant removal has not been directly documented, many researchers suggest infiltration plays a significant role (Table 1). …
