The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson Jan 1997

The Contributions Of J. A. Udden To An Understanding Of Iowa Geology, Richard C. Anderson

Journal of the Iowa Academy of Science: JIAS

Johan August Udden served on the faculty of Augustana College from 1888 until 1911. His research during that time was directed toward an understanding of the geology of areas close at hand, the region around Rock Island and nearby areas in Iowa and Illinois. Udden's most significant contributions to Iowa geology were in his treatment of 1) Paleozoic, Cretaceous, and Quaternary stratigraphy; 2) subsurface geology, including information on bedrock elevations and topography; 3) characteristics and origin of the loess. Most of this information was included in the Annual Reports of the Iowa Geological Survey published between 1899 and 1903. He …

A Fairy Tale About Teacher Research In Conservative Times, Collaborative Action Researchers For Democratic Communities, Suzanne Soohoo, Lani Martin, Tom Wilson, Emily Wolk Jan 1997

A Fairy Tale About Teacher Research In Conservative Times, Collaborative Action Researchers For Democratic Communities, Suzanne Soohoo, Lani Martin, Tom Wilson, Emily Wolk

Education Faculty Articles and Research

Collaborative action research involves creating spaces for thoughtful discussion, not only about classroom practices but about schooling in general. The fairy tale created by the authors of this piece raises questions about autonomy, control, and the need for participation in the context of the current conservative climate.

Ray Optics On Surfaces, Mostafa Ghandehari Jan 1997

Ray Optics On Surfaces, Mostafa Ghandehari

Mathematics Technical Papers - Archive

Variational techniques are used to find path of light rays on surfaces. Using Fermat's principle of least time the problem is treated as a constraint optimization to obtain a system of partial differential equations.

Estimating Transition Probabilities From Aggregate Samples Augmented By Haphazard Recaptures Ii. The Case Of Covariates., Chien-Pai Han, D. L. Hawkins Jan 1997

Estimating Transition Probabilities From Aggregate Samples Augmented By Haphazard Recaptures Ii. The Case Of Covariates., Chien-Pai Han, D. L. Hawkins

Mathematics Technical Papers - Archive

The paper extends the authors' earlier methods for estimating transition probabilities, by combining aggregate and haphazard recapture data, to the case of categorical covariates. Both fixed and time-dependent covariates are considered. A two-stage estimation procedure is proposed. The first stage uses a Markov model to estimate multivariate transition probabilities for the response and all covariates. The second stage uses the Stage 1 estimates to model covariate effects. The required number of sampling waves depends only on the number of response levels and time-dependent covariate levels — and not on the number of fixed covariate levels. Recommendations are given for the …

Snell's Law In Normed Linear Planes, Mostafa Ghandehari Jan 1997

Snell's Law In Normed Linear Planes, Mostafa Ghandehari

Mathematics Technical Papers - Archive

The method of Lagrange multipliers is used to find a reflection principle in a real normed linear plane with smooth unit circle. A generalization of Snell's law of refraction with two different norms is given. The case where the unit circles of the two norms are Euclidean circles with different radii leads to Snell's law.

A Value For Digraph-Restricted Games, Oltion Voshtina Jan 1997

A Value For Digraph-Restricted Games, Oltion Voshtina

Mathematics Technical Papers - Archive

Digraph-restricted games model situations where some of the players, due to the lack of communication among them, are unable to cooperate. A digraph-restricted game v is defined as a function from the set of feasible coalitions to the reals. By strengthening the symmetry axiom we obtain an extension of the Shapley value for this class of games. Key words. Shapley value, cooperative game, directed graph.

Separating K+/- From Pi+/- Using In-Flight Decays To Mu+/- + Nu, Wilfred J. Braithwaite, Edwin S. Braithwaite Jan 1997

Separating K+/- From Pi+/- Using In-Flight Decays To Mu+/- + Nu, Wilfred J. Braithwaite, Edwin S. Braithwaite

Journal of the Arkansas Academy of Science

A method is presented for completely distinguishing between charged kaons and charged pions by using their charged muon (plus neutrino) decays (with neutrinos undetected) for meson laboratory momenta up to 1000 MeV/c. When either a charged kaon or a charged pion decays into a muon and a neutrino, momentum-energy (four-momentum) conservation will be used to provide unique "kinematic trajectories" for distinguishing kaon decays from pion decays when the change in three-momentum of the muon from that of either parent kaon or pion is measured (or simulated). Ina magnetic field, observation of a tracked particle showing a "kink" and/or a change …

The Treatment Of Vegetable Processing Waste Water Using A Pilot Scale Sequencing Batch Reactor Activated Sludge Process, Peter Hassett Jan 1997

The Treatment Of Vegetable Processing Waste Water Using A Pilot Scale Sequencing Batch Reactor Activated Sludge Process, Peter Hassett

Theses

The SBR process is a discontinuous, unsteady state process and has developed popularity in many countries assisted by reliable control technology for example programmable logic control. A typical SBR installation achieves equalisation, aeration and clarification of batches of wastewater on a timed sequence in one basin. This is in contrast to a volume sequenced process such as the conventional continuous stirred tank reactor where individual treatment objectives are met in separate basins. Advantages include, flexability, minimum energy input, consistent effluent quality and inhibition of filament organism growth by properly controlling substrate concentration and aeration sequences. Nitrification, denitrification and Bio-P removal …

Habitat Area Requirements Of Prairie Wetland Birds In Eastern South Dakota, David E. Naugle Jan 1997

Habitat Area Requirements Of Prairie Wetland Birds In Eastern South Dakota, David E. Naugle

Electronic Theses and Dissertations

The influence of area and vegetation structure on bird use of 830 semipermanent and seasonal wetlands (0.2-217.5 ha) was studied to evaluate vegetative needs and habitat area requirements of 20 breeding wetland bird species in eastern South Dakota in 1995-1996. Vegetative preferences of species varied, but most waterfowl and nongame species occur e4i more frequently in wetlands with intermediate cover-to-water ratios whereas five over-water nesting or secretive nongame species were found in wetlands with greater coverage of emergent vegetation. The occurrence of four nongame species that depend on vegetative structure to support the weight of their over-water nests also was …

Artificial Neural Network Based Model For Computation Of Injection Mould Complexity, Rawin Raviwongse, Venkat Allada Jan 1997

Artificial Neural Network Based Model For Computation Of Injection Mould Complexity, Rawin Raviwongse, Venkat Allada

Engineering Management and Systems Engineering Faculty Research & Creative Works

The cost of injection mould construction depends primarily on the mould complexity. The ability to estimate the mould complexity before releasing the final drawings for construction purposes will greatly help the designers to understand the implications of their design on cost. Mould complexity depends on several factors such as part geometry, parting line, materials, and number of cavities per mould. In most industries, the mould complexity evaluation is performed manually based on past experiences of mould makers. Faced with a shortage of experienced mould makers, there is a pressing need for development of computer-aided tools for mould complexity evaluation. In …
