This paper discusses a new concept generation technique that improves upon a previous automated concept generation theory and algorithm developed by Bryant, et al. at the University of Missouri – Rolla. The previous automated concept generation algorithm utilizes the design knowledge present in a repository to produce an array of partial concept solutions. While the previous algorithm is capable of handling branched functional models, it does not efficiently remove all of the infeasible partial solutions to leave only whole concepts in the final results. A matrix-based algorithm is presented in this paper that utilizes the result from the previous concept generation algorithm and solves for complete solutions of branched concepts. The presented algorithm eliminates incomplete and infeasible concepts or components from the results and generates a set of full solutions for further analysis by a designer. The details of the algorithm are described in this paper, and a peanut-sheller example is used to illustrate the effective use of the algorithm for producing branched concept variants.

This paper builds on previous concept generation techniques explored at the University of Missouri - Rolla and presents an interactive concept generation tool aimed specifically at the early concept generation phase of the design process. Research into automated concept generation design theories led to the creation of two distinct design tools: an automated morphological search that presents a designer with a static matrix of solutions that solve the desired input functionality and a computational concept generation algorithm that presents a designer with a static list of compatible component chains that solve the desired input functionality. The merger of both the automated morphological matrix and concept generation algorithm yields an interactive concept generator that allows the user to select specific solution components while receiving instantaneous feedback on component compatibility. The research presented evaluates the conceptual results from the hybrid morphological matrix approach and compares interactively constructed solutions to those returned by the non-interactive automated morphological matrix generator using a dog food sample packet counter as a case study.

This paper explores the applicability of the most recently developed methods in functional modeling to Design for Six Sigma transfer function development and requirements flowdown. An example created during a collaborative research project between the General Motors R&D Center and the University of Missouri – Rolla is used to demonstrate the benefits of using standardized functional modeling during conceptual design. The proposed standard for creating the functional models is the Functional Basis. The Functional Basis is a list of function and flow terms that can be used to describe electro-mechanical systems. The example presented in this paper is based on the parking brake system of a passenger car. Module heuristics, function-based rules for partitioning systems, were used to define the sub-systems during the requirements flowdown example. The functional modeling techniques used in this example provide a standard method of capturing current engineering design knowledge while allowing additional knowledge to be discovered.

In recent years an increasing emphasis has been placed on the study of high temperature intermetallic compounds for possible aerospace applications. One group of interest is the B2 aiuminides. This group of intermetaliics has a very high melting temperature, good high temperature, and excellent specific strength. These qualities make it a candidate for applications such as turbine engines. The B2 aiuminides exist over a wide range of compositions and also have a large solubility for third element substitutional additions, which may allow alloying additions to overcome their major drawback, their brittle nature.One B2 aluminide currently being studied is cobalt aluminide. Optical microscopy of CoAl alloys produced at the University of Missouri-Rolla showed a dramatic decrease in the grain size which affects the yield strength and flow stress of long range ordered alloys, and a change in the grain shape with the addition of 0.5 % boron.

The Missouri Automated Radiology System recently passed its tenth year of clinical operation at the University of Missouri. This article presents the views of a radiologist who has been instrumental in the conceptual development and administrative support of MARS for most of this period, an economist who evaluated MARS from 1972 to 1974 as part of her doctoral dissertation, and a computer scientist who has worked for two years in the development of a Standard MUMPS version of MARS. The first section provides a historical perspective. The second deals with economic considerations of the present MARS system, and suggests those improvements which offer the greatest economic benefits. The final section discusses the new approaches employed in the latest version of MARS, as well as areas for further application in the overall radiology and hospital environment. A complete bibliography on MARS is provided for further reading.

This paper presents the results of a study that demonstrates an effective use of the Web as a tool to increase motivation and thus promote reading and writing skills in Spanish as well as a deeper sense of the culture of the Spanish speaking world. In the study, thirty students of second year Spanish at the University of New South Wales were required to prepare an itinerary for a trip to a Spanish speaking country of their choice using the WWW as the only resource. In general our findings regarding improved language skills were consistent with the literature: an increase of vocabulary, more use of references, more student initiated interactions and greater interactivity in the classroom amongst students were observed. There was, however, one aspect, linguistic accuracy, in which improvement was not greatly noted. The data collected confirms that a task-oriented Web based course can increase the motivation of students, improve the scope of their reading, and enhance their perception of the target culture, all with a great effect on range of language explored, learned and re-processed, but a much lesser effect on the accuracy of written language produced.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] This dissertation examines post-World War II student civil rights activism at two Midwestern college campuses, the University of Missouri (MU) and the University of Kansas (KU). Missouri and Kansas have conflicting histories concerning race dating back to Bleeding Kansas and the history of race relations on the campuses of KU and MU. This history is especially complicated during the period between 1946 and 1954 because of heightened student activism that challenged racial injustices. Race relations on campus largely mirrored that of the state's political environment, with KU having integrated in the 19th century, whereas MU did not desegregate until 1950. However, the same did not apply to the success of student activists at each school where MU students found success fighting against discriminatory practices in Columbia, whereas local business leaders and the university administration stymied KU students. The dissertation examines the exchange of ideas and strategy among students, which occurred through athletics, debates, guest speakers, and various regional and national groups. In particular, the study argues that campus spaces, such as residential co-ops and student organizations, were deeply significant because they served as incubators of activism by offering students a place to talk about racial and social injustice and plan ways to challenge these inequalities and effect change on campus and in the broader community.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This novel is the story of Tianne, a twenty-eight-year-old stained glass artist. She works two part-time jobs as a clerk at a stained glass supply store, and as an adjunct instructor at a community college. Her boyfriend Jeremiah is an academic adviser at the same college, but wants a career performing in comedy clubs. He uses a wheelchair due to spina bifida, and is cheerfully blunt that he could die from an undetected kidney infection. Tianne wrangles her own invisible disability, since endometriosis causes her to have awful cramps during her period that can keep her home from work. Tianne loves her jobs but worries about bills after her car breaks down. She envies Jeremiah's financial stability until he's fired for speaking his mind too many times to administration. Tianne fears for his health insurance coverage, while Jeremiah debates careers as a high school guidance counselor or touring comedy clubs. Throughout the book Tianne tries to chart a path though the instabilities of her body, Jeremiah's body, their career paths, and their romantic relationship, knowing that nothing is permanent. Hers is a story not of looking for stability, but coming to terms with instability, and finding spaces of adaptation to constant change.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation outlines several results about prime characteristic singularities for which the nilpotent part under the induced Frobenius action on local cohomology is either finite colength or the entire module, collectively referred to here as nilpotent singularities. First, we establish a sufficient condition for the finiteness of the Frobenius test exponent for a local ring and apply it to conclude that nilpotent singularities have finite Frobenius test exponent. In joint work with Jennifer Kenkel, Thomas Polstra, and Austyn Simpson, we show that under mild conditions nilpotent singularities descend and ascend along faithfully flat maps. Consequently, we then prove that the loci of primes which are weakly F-nilpotent and F-nilpotent are open in the Zariski topology for rings which are either F-finite or essentially of fiiite type over an excellent local ring.
