A study of drop-outs from the accelerated mathematics classes of the Portland public schools, Portland, Oregon

Creator:: Palmer, Joyce Eileen
Abstract:: Statement of the problem: The study sought to determine whether certain measurable differences existed between students who had withdrawn after acceptance into the accelerated mathematics classes in the Portland schools and students who had persisted after acceptance into the program. Examined were: scores on the Iowa Tests of Basic Skills,...
Resource Type:: Masters Thesis
Full Text:: district. Statistics: The parametric statistic, Fisher's t, was employed to test the difference

Tangential families of study vectors

Creator:: Johnson, Robert C. (Robert Carl)
Abstract:: This paper is devoted to the study of families of tangent lines to curves in Euclidean three dimensional space by the medium of a particular representation for lines. First, a ring of elements called dual numbers is described, and a vector space over this ring, whose elements are called dual...

On the theory of heat transport in a semi-infinite solid

Creator:: Wong, James Teng
Abstract:: The paper concerns itself with the problem of heat transport in a homogeneous, incompressible, isotropic, semi-infinite solid whose boundary is nonstationary. The methods of solution in the one dimensional case are discussed. Numerical examples and a method for arriving at the solutions published by Bailey and Lakin in their paper...

Late Pleistocene Lithic Technological Organization on the Southern Oregon Coast : Investigations at Indian Sands (35-CU-67C)

Creator:: Willis, Samuel C.
Abstract:: Excavations conducted at Indian Sands (35-CU-67C), located along Oregon's southern coast, during 2002 and 2003 identified two discreet, artifact-bearing stratigraphic units. The uppermost unit is a deflated surface containing burnt shell and lithic artifacts associated with early Holocene ¹⁴C dates, while the underlying unit contained only lithic tools and debitage,...

The extension problem for functions invariant under a group

Creator:: Chang, Bai-Ching
Abstract:: Consider a transformation group G operating on a space X and a G- invariant function f defined on a G- invariant subset of X. By imposing suitable conditions on X, G, f and A, the author derives sufficient conditions for extending f invariantly to the whole space, and thus generalizing...

A classification of determinants whose evaluations have appeared in periodical literature

Creator:: Liebetrau, Albert M.
Abstract:: This paper is a classification of 181 problems, each of which involves the evaluation or application of determinants. The problems are those which have appeared in the "Problems and Solutions" sections of the American Mathematical Monthly, Deutsche Mathematiker-Vereinigung Jahresbricht, Mathematics Magazine, and School Science and Mathematics. The problems are classified,...

Stability of flows of thermo-viscoelastic fluids between rotating coaxial circular cylinders

Creator:: Ghandour, Nabil Nassib
Abstract:: We investigate in this thesis, the problem of stability of thermo-viscoelastic fluid flow between rotating coaxial cylinders. By using the thermo-viscoelastic constitutive equations given by Eringen, we reduce the equations of motion into a form suitable for stability analysis. The course of reduction which we follow yields some interesting intermediate...

A revision of the North American species of Pactopus Leconte and Trixagus Kugelann (Coleoptera: Throscidae)

Creator:: Yensen, Arthur Eric
Abstract:: This study was undertaken to find means of separating the morphologically similar species of North American Trixagus and to bring together information on Trixagus and Pactopus. A key to separate the world's eight genera of extant Throscidae is presented for the first time. A key to the five species of...
