Optimization Using Replicators, Anil Ravindran Menon, Kishan Mehrotra, Chilukuri K. Mohan, Sanjay Ranka
College of Engineering and Computer Science - Former Departments, Centers, Institutes and Projects
Replicator systems are among the simplest complex systems and can be considered to be at the foundation of many popularly used models ranging from theories of evolution and neurobiology to sociobiology and ecology. This paper presents the first successful application 2 of replicators to optimization problems. For a graph bi-partitioning problem with 50,000 nodes and 300,000 edges, for instance, close to optimal solutions were obtained in a few hundred iterations. Replicators provide a potentially powerful new tool to solve other optimization problems as well.
Biological Processes: Relationships Between Earthworms And Soil Temperature, Edwin C. Berry, Jerry K. Radke
Biological Processes: Relationships Between Earthworms And Soil Temperature, Edwin C. Berry, Jerry K. Radke
Journal of the Minnesota Academy of Science
Soil fauna play important roles in many soil processes and conditions which relate to agricultural systems. Earthworms are credited with enhancing soil fertility and soil physical properties by their feeding and burrowing activities. Most research on earthworms has focused on the warmer seasons of the year and relatively little is known about earthworm activity and survival during the portion of the year with frozen soils. Earthworms may survive winter by acclimatization, aestivation, or by burrowing to deeper depths where the soil is not frozen. More research is needed on the fate of earthworms in frozen soils. Suggested research areas include: …

Wetlands/Groundwater Quality In Agricultural Landscapes, D. H. Rickerl, D. E. Kringen, T. A. Machacek
Journal of the Minnesota Academy of Science
In the Prairie Pothole Region (PPR - SO, NO, MN, IA), wetlands classified as "semi-permanent" or "seasonal" can act as groundwater recharge sites. The nutrient filtering capacity of wetlands has been investigated for both natural and constructed wetlands linked to surface water, but there is little information available on their subsequent impact on groundwater quality. This study investigates four seasonal and two semi-permanent wetlands in the PPR of eastern South Dakota. Transitional no-till (TNT) and organic farm (ORG) management systems border the wetlands. The objective is to determine the effects of farm management system on wetland surface water and groundwater …

Chemical And Biological Monitoring Of A Constructed Wetland On Jones Branch Treating Acid Mine Drainage, Barbara A. Ramey, George Chalfant, Jon A. Walker
Chemical And Biological Monitoring Of A Constructed Wetland On Jones Branch Treating Acid Mine Drainage, Barbara A. Ramey, George Chalfant, Jon A. Walker
KWRRI Research Reports
Acid mine drainage (AMD) from an abandoned underground coal mine in the Jones Branch watershed in McCreary County, KY, substantially reduced water quality in Jones Branch. Downstream from the mine seeps, the pH was routinely below 4.5 and concentrations of most heavy metals, especially iron, were elevated. A cattail wetland (1,022 m2) was constructed on Jones Branch in 1988-1989 to obviate the effects of the AMD. Monthly chemical monitoring was performed on the water from above, from below, from the inlet and outlet of the wetland, and from the 25 cells within the wetland. Based on chemical monitoring, …

Analysis Of Rule Sets Generated By The Cn2, Id3, And Multiple Convergence Symbolic Learning Methods, Elizabeth M. Boll, Daniel C. St. Clair
Mathematics and Statistics Faculty Research & Creative Works
The ability to learn has long been an area of interest to researchers in artificial intelligence. Symbolic inductive learning algorithms have evolved as a class of algorithms that can be used to learn concepts from training examples. The knowledge acquired is represented in the form of rules. Since symbolic learning methods develop distinctive sets of rules when given identical training data, questions arise as to the quality of the different rule sets produced. The results of this research provide techniques for comparing and analyzing rule sets. Numerous rule sets were generated using three well-known symbolic learning methods; Quinlan's ID3, Clark …

Keeping Our Habitat Healthy: A Thematic Unit For Teaching Environmental Awareness For Grades 3-5, Pamela A. Shetler
Theses Digitization Project
There are many curriculum guides that address environmental education. Classroom teachers do not have the time to obtain and search all of these guides. This curriculum was developed by searching numerous manuals for appropriate lessons, developing a cohesive unit, and field testing the lessons on students in two classrooms. The project, as a whole, offers teachers a thematic, multi-disciplinary, hands-on, literature based method of developing students' appreciation and understanding of the world in which they live.

Wildlife Conservation, Zoos And Animal Protection: A Strategic Analysis, Andrew N. Rowan
Wildlife Conservation, Zoos And Animal Protection: A Strategic Analysis, Andrew N. Rowan
The publication consists of the proceedings of a workshop, sponsored by the Gilman Foundation, and held in April of 1994 at the White Oak Conservation Center in Florida. About thirty participants were invited from zoos, animal protection groups and academic institutions to discuss concepts such as wild, captive and tame; animal well-being in the wild and in zoos; and protecting individuals versus conserving populations. In order to maximize the time engaged in discussion, several individuals were identified to prepare target articles which were distributed to all participants before the meeting. These articles form the main chapters in this book. Other …

Wildlife Conservation and Management
A modelling effort using POP-II software was presented to show the effects of altering the harvest structure of the reduction. The relatively high harvests of the last two years may result in maintaining the current Park population levels. A variety of scenarios increasing the number and proportion of cows harvested show the greater effects cow harvests have on reducing the population relative to bull harvests.

Lighthouse Coal Bed Methane Project Environmental Assessment, United States Department Of The Interior Bureau Of Land Management
Environmental Assessments (WY)
American Oil and Gas Corporation (American), also doing business as Martens and Peck Operating, proposes a coal bed methane (CBM) project called the Lighthouse project near Gillette, Wyoming in central Campbell County just south of the Marquiss CBM project. Wells drilled in the project area would be from intermingled private, state, and federal oil and gas properties. At full production, American hopes to produce methane gas from a maximum of 200 wells completed in the Wyodak coal seam in the Lighthouse project area. Of the 200 wells, 100 would produce federally owned methane gas.

Rangeland Reference Areas : Summary Of Cooperative Project Between The Western Australian Department Of Agriculture And The Environmental Protection Authority, D A. Blood
Resource management technical reports
The development of agriculture in south-western Australia has been characterised by the replacement of deep-rooted, perennial species of native vegetation with shallow-rooted, annual species. Except for the high rainfall areas, the native vegetation was able to intercept and transpire nearly all of the rainfall resulting in low stream flows and recharge to a groundwater system which was typically deep and restricted to the major valleys. The lack of surface or groundwater movement out of inland catchments used large quantities of cyclic salts to become stored in the regolith. Although annual crops and pastures can be high water users, they are …
