Information Theoretic Mask Analysis Of Rainfall Time Series Data, Martin Zwick, Hui Shu, Roy Koch

Complex Systems Faculty Publications and Presentations

This study explores an information-theoretic/log-linear approach to multivariate time series analysis. The method is applied to daily rainfall data(4 sites, 9 years), originally quantitative but here treated as dichotomous. The analysis ascertains which lagged variables are most predictive of future rainfall and how season can be optimally defined as an auxiliary predicting parameter. Call the rainfall variables at the four sites A...D, and collectively, Z, the lagged site variables at t-1, E,,,H, at t-2, I...L, etc. and the seasonal parameter, S. The best model, reducing the Shannon uncertainty, u(Z), by 22%. is HGFSJK Z, where the independent variables, H through …

Paleokarst And Associated Mineralization At The Linwood Mine, Scott County Iowa, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Operations at the Linwood Mine in Scott County, Iowa, have exposed, on two working levels, extensive pre-Pennsylvanian paleokarst and associated sediment fillings and mineralization in Middle Devonian limestones. Cavities in Davenport-Spring Grove host rocks range up to 270 meters in length and are virtually all filled with fluviatile sediment. Cavities in Cedar Rapids host rocks, on average, are smaller and some are unfilled. Limestone dissolution was controlled by high-angle fractures with a wide variety of orientations and by bedding plane and stylolitic partings. Dissolutional features on both levels of the mine provide evidence for phreatic and vadose processes. Most of …

Nonrecursive Incremental Evaluation Of Datalog Queries, Guozhu Dong, Jianwen Su, Rodney Topor

Kno.e.sis Publications

We consider the problem of repeatedly evaluating the same (computationally expensive) query to a database that is being updated between successive query requests. In this situation, it should be possible to use the difference between successive database states and the answer to the query in one state to reduce the cost of evaluating the query in the next state. We use nonrecursive Datalog (which are unions of conjunctive queries) to compute the differences, and call this process “incremental query evaluation using conjunctive queries”. After formalizing the notion of incremental query evaluation using conjunctive queries, we give an algorithm that constructs, …

Inheritance And Number Of Genes Affecting Quantitative Traits Within F2 Maize Populations, D. H. Schmidt, A. R. Hallauer

Journal of the Iowa Academy of Science: JIAS

Populations derived from crosses of elite genotypes are commonly used in plant breeding programs. Knowledge of the genetic variation among individuals and their progenies within F2 populations is essential for effective selection of important traits. The genetic variation and number of effective factors affecting the expression of quantitative traits within 30 F2 maize (Zea mays L.) populations were determined by different methods suggested for study of F2 populations. Estimates of heritability and number of effective factors varied among F2 populations for each trait, primarily because of the differences in trait expression between parents of crosses and the environmental effects upon …

Comparison Of The Effects Of Saporin-Igg Injections Into The Nucleus Basalis Magnocellularis And Medial Septal Area Of Male Rat As Assessed By The Morris Water Maze Task, Alexander R. V. Mccampbell '95

Honors Projects

Alzheimer's disease currently afflicts approximately 4 million people in the United States, with 100,000 new cases being reported each year. As post mortem examination of AD patientsI brains has revealed a significant decrease in the number of cholinergic neurons, one approach we have taken is to look at the correlation between the depletion of certain cholinergic markers in animals and the resulting behavioral deficits. Two regions of specific interest are the medial septal area (MSA) and the nucleus basalis magnocellularis (NBM). These regions are important because they are the major source of cholinergic neurons in the brain, they are selectively …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …

Diversity Dynamics In Static Resource Models, Mark Bedau, Matt Giger, Martin Zwick

Complex Systems Faculty Publications and Presentations

We define three information-theoretic methods for measuring genetic diversity and compare the dynamics of these measures in simple evolutionary models consisting of a population of agents living, reproducing, and dying while competing for resources. The models are "static resource models" i.e., the distribution of resources is constant for all time. Simulation of these models shows that (i) focusing the diversity measures on used alleles and loci especially highlights the adaptive dynamics of diversity, and (ii) even though resources are static, the evolving interactions among the agents makes the effective environment for evolution dynamic.

Keywords: diversity, information theory, evolutionary model, static …

Cavity Protection Techniques For Red-Cockaded Woodpeckers, Warren G. Montague

Journal of the Arkansas Academy of Science

Population growth of red-cockaded woodpeckers (Picoides borealis) is often limited by the availability of suitable cavities. Structural damage to natural and artificial cavities intended for use by P. borealis is common. Roost and nest cavities of P. borealis often become occupied by other cavity-dependent species. Techniques for preventing damage to artificial cavities and for deterring southern flying squirrel (Glaucomys volans) use of otherwise serviceable cavities are described. Such cavity protection techniques may be necessary to prevent extirpation of small, isolated populations of P. borealis.

5'-Nucleotidase And Thrombin-Like Activities Of Selected Crotalid Venoms, Ali M.S. Shams, Dewey H. Sifford, Bob D. Johnson

Journal of the Arkansas Academy of Science

Thrombin-like activities were not observed inCrotalus basiliscus, C. molossus and C. scutulatus scutulatus crude venoms. 5'-Nucleotidase specific activities of 0.863, 0.273 and 5.520 units/mg of crude venom protein were observed inC. basiliscus, C. molossus and C. s. scutulatus venoms, respectively. Concanavalin ASepharose 4 B (Con A)affinitychromatography yielded two fractions from each of the crude venoms. Ineach instance, both fractions exhibited 5'-nucleotidase activities and the Con A-binding proteins had higher activities than the Con A-nonbinding proteins. 5'-Nucleotidase activities inthe DEAESephadex A-50 chromatographic fractions were localized in the first elution fraction and the last fraction(s) to elute. EDTAhad no effect on the …

Study Of The Time Efficiency And Volume Of Wood Used For Three Types Of Stove In The Salitrón Community Of San Juan Ermita, Department Of Chiquimula, Fredy Samuel Coronado López

Theses and Dissertations

In developing countries such as Guatemala, firewood is increasingly being used for cooking in most rural areas. Consequently, there is a shortage of firewood in these areas beca use trees do not grow at the same rate as they are consumed. Some authors report that 90% of the heat from firewood is lost during combustion. Several alternatives to open pit fires exist to reduce the amount of firewood used. However, these alternatives need to be evaluated to determine their efficiency. This project compared the time efficiency and volume of firewood used in the Finlandia style improved stoves, Josefina stoves, and …

A Ten-Year History Of The Demography And Productivity Of An Arctic Wolf Pack, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

A pack of two to eight adult wolves (Canis lupus arctos) and their pups was observed during ten summers (1986–95) on Ellesmere Island, Northwest Territories, Canada. The author habituated the wolf pack to his presence in the first summer and reinforced the habituation each summer thereafter. The first alpha female produced four to six pups each year between 1986 and 1989. However, her daughter, who succeeded her as the alpha female, produced only one to three pups each year between 1990 and 1992 and in 1994, and apparently did not whelp in 1993 or in 1995. The tenure …

Cluster Analysis Of The Coprolites From Antelope House: Implications For Anasazi Diet And Cuisine, Mark Q. Sutton, Karl Reinhard

Karl Reinhard Publications

This paper reports on a cluster analysis of 155 coprolites from Antelope House, a prehistoric Anasazi site in Canyon de Chelly, Arizona. The analysis revealed three primary clusters; whole kernel maize, milled maize, and nonmaize, which we believe to represent seasonal- and preference-related cuisine. Protein residue analysis on a subsample of the specimens added depth to the analysis.

Food Systems: Community-Shared Agriculture, A Means Of Empowerment And Social Vitality, Godwin Samuel Ashiabi

Theses and Dissertations (Comprehensive)

In this thesis I focused on the Community Shared Agriculture (CSA) as an alternative form of farming to industrialized agriculture. CSA connects the growers of food directly with the people who eat it, in a way where everyone shares the benefits and risks involved in agriculture. The Huron Community Garden in Goderich is the setting that was selected for this study because of its five-year history as a form of CSA. A naturalistic participant-observation mode of enquiry was employed. As a participant-observer, I was involved in all activities of the Garden—weeding, tilling of the ground, transplanting of seedlings, watering of …
