Diagrams Based On Structured Object Perception, Pourang Irani, Colin Ware

Center for Coastal and Ocean Mapping

Most diagrams, particularly those used in software engineering, are line drawings consisting of nodes drawn as rectangles or circles, and edges drawn as lines linking them. In the present paper we review some of the literature on human perception to develop guidelines for effective diagram drawing. Particular attention is paid to structural object recognition theory. According to this theory as objects are perceived they are decomposed into 3D set of primitives called geons, together with the skeleton structure connecting them. We present a set of guidelines for drawing variations on node-link diagrams using geon-like primitives, and provide some examples. Results …

Sampling Systems Matched To Input Processes And Image Classes, Ajit Bopardikar

Theses

This dissertation investigates sampling and reconstruction of wide sense stationary (WSS) random processes from their sample "random variables". In this context, two types of sampling systems are studied, namely, interpolation and approximation sampling systems. We aim to determine the properties of the filters in these systems that minimize the mean squared error between the input process and the process reconstructed from its samples. More specifically, for the interpolation sampling system we seek and obtain a closed form expression for an interpolation filter that is optimal in this sense. Likewise, for the approximation sampling system we derive a closed form expression …

On The Behavior Of A Class Of Patched Plates During Cooling, Anette M. Karlsson, W. J. Bottega

Mechanical Engineering Faculty Publications

The behavior of patched beam-plates during uniform cooling is considered. A non-linear formulation is adopted and the problems of interest are solved analytically yielding exact results within the context of the mathematical model employed. Three non-dimensional parameters corresponding to (i) a loading parameter, (ii) a critical temperature and (iii) a critical membrane force, are seen to characterize the response of the composite structure. Stability is considered and critical behavior includes bifurcation and asymptotic buckling, non-trivial “groundstates”, and demarcation and transition in deflection direction. Extensive numerical simulations based on analytical solutions are performed. Results are presented for various loading and support …

Estimating Change Over Time From Aggregate Samples Plus Partial Transition Data, Chien-Pai Han, D. L. Hawkins

Mathematics Technical Papers - Archive

As such, the paper has two basic thrusts. The first is that to obtain efficient estimates of change measures (e.g. of transition probabilities) based on aggregate data, auxiliary data will in general be needed; several potentially useful auxiliary sampling schemes are discussed. The second thrust is the manner in which estimates from the such varied sampling schemes can be combined to achieve such efficient estimates. Since it either directly or indirectly suggests many possible longitudinal study designs, the paper necessarily cannot provide real examples of all (or even most) of the study designs considered. Indeed, the main point here is …

Banzhaf Permission Values For Games With Permission Structure, Rene Van Den Brink

Mathematics Technical Papers - Archive

A game with a permission structure describes a situation in which cooperation possibilities in a cooperative game with transferable utility are limited because there are players that need permission from other players before they are allowed to cooperate. In the conjunctive approach it is assumed that every player needs permission from all its direct superiors. In the disjunctive approach it is assumed that each player only needs permission from at least one of its direct superiors. Both approaches yield different modified games which take account of the limited cooperation possibilities. Applying the Banzhaf value to these modified games yields allocation …

Grade Level Files For Third And Fifth Grades, Courtney Rasband

Undergraduate Honors Capstone Projects

For my Associate Teaching and Honors project, I decided to do different grade level files. I thought this would be an appropriate project in the event that I get hired to teach in a grade other than first. I am glad that I was able to do this project because it expanded my ideas for teaching not only in the grades that I researched, but also in other grades because I will be able to adapt the ideas that I found.

Safety Orientation For Non-Flying Partners Of Pilots, Barbara J. Wall

Undergraduate Honors Capstone Projects

I became interested in the Women in Aviation organization while searching for scholarships during 1999. This professional organization, not just for women, is instrumental in providing hundreds of thousands of dollars for women to expand their flight certificates and education. I began gathering information for starting a local chapter when another student was not able to continue her pursuit of this project.

A New Perspective On Classification, Guohua Zhao

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The idea of voting multiple decision rules was introduced in to statistics by Breiman. He used bootstrap samples to build different decision rules, and then aggregated them by majority voting (bagging). In regression, bagging gives improved predictors by reducing the variance (random variation), while keeping the bias (systematic error) the same. Breiman introduced the idea of bias and variance for classification to explain how bagging works. However, Friedman showed that for the two-class situation, bias and variance influence the classification error in a very different way than they do in the regression case.

Motivation Among Students With Learning Disabilities, April H. Conti

Theses and Dissertations

The purpose of this study was to examine whether intrinsic motivation is a major factor in explaining academic performance deficits in children with learning disabilities. Harter's Scale of Intrinsic Versus Extrinsic Orientation in the Classroom was given to 34 students with learning disabilities and 36 students without learning disabilities from Grades 4 to 6 from a suburban, middle-class school district located in Southeastern New Jersey. It was proposed that students with learning disabilities were less intrinsically motivated than students without identified learning disabilities. However, the general pattern of results derived from a T-Test for Independent Samples did not show a …

Evolution Of Positive Solution Curves In Semipositone Problems With Concave Nonlinearities, Alfonso Castro, Sudhasree Gadam, Ratnasingham Shivaji

All HMC Faculty Publications and Research

We study the existence, multiplicity, and stability of positive solutions to -u''(x) = λf(u(x)) for x є (-1,1), u(-1) = 0 = u(1), where λ > 0 and f:[0,∞)→R is monotonically increasing and concave with f(0) < 0 (semipositone). We establish that f should be appropriately concave (by establishing conditions on f) to allow multiple positive solutions. For any λ > 0, we obtain the exact number of positive solutions as a function of f(t)/t. We follow several families of nonlinearities f for which f(∞) := lim t→∞ f(t) > 0 and study how the positive solution curves to the above problem evolve. Also, we give examples where our results apply. This work extends the work of A. Castro and R. Shivaji (1988, Proc. Roy. Soc. Edinburgh …

Infrared Classification Of Galactic Objects, Željko Ivezić, Moshe Elitzur

Physics and Astronomy Faculty Publications

Unbiased analysis shows that IRAS data reliably differentiate between the early and late stages of stellar evolution because objects at these stages clearly segregate in infrared color-color diagrams. Structure in these diagrams is primarily controlled by the density distribution of circumstellar dust. The density profile around older objects is the steepest, declining as r^-2, while young objects have profiles that vary as r^-3/2 and flatter. The different density profiles reflect the different dynamics that govern the different environments. Our analysis also shows that high-mass star formation is strongly concentrated within ~5 kpc around the Galactic center, in …

Zno Diode Fabricated By Excimer-Laser Doping, Toru Aoki, Yoshinori Hatanaka, David C. Look

Physics Faculty Publications

A ZnO diode was fabricated by using a laser-doping technique to form a p-type ZnO layer on an n-type ZnO substrate. A zinc-phosphide compound, used as a phosphorous source, was deposited on the ZnO wafer and subjected to excimer-laser pulses. The current–voltage characteristics showed a diode characteristic between the phosphorous-doped p-layer and the n-type substrate. Moreover, light emission, with a band-edge component, was observed by forward current injection at 110 K.

Quantitative Measurement Of Guest–Host Interactions In Supramolecular Systems: A Comparative Brillouin Scattering Study Of The Dianin’S Compound Clathrand And Two Of Its Isostructural Clathrates, C.A. Sandstedt, D. Michalski, Craig J. Eckhardt

Craig J. Eckhardt Publications

Single, isomorphous crystals of the guest-free clathrand of Dianin’s compound and two of its clathrates containing two ethanols and a heptanol, respectively, have been studied by Brillouin scattering to obtain their complete elastic constant tensors. The values found for individual elastic constants are related to microscopic interactions of the guests and host cage using the clathrand as the reference. Direct correlation of the interference of the guest heptanol molecule with the hexamer hydrogen-bonded network of the host cage to reduced stiffness of this clathrate is demonstrated. In contrast, the ethanol-containing clathrate is demonstrated to have negligible interaction of the guests …

Building The Veco Online Community : A Model For Encouraging Novices., Michelle Williams, Janine Bowes.

Australian Journal of Teacher Education

Building online networks and designing network activity is becoming central to how educators and other education-based professionals work, train others and teach students. It is only since 1995 that Internet connectivity in Australia has provided the critical mass and momentum which alters how people work, who they work with and how they learn. Thus the business of helping professional networks develop and become part of the lives of their members is uncharted territory and an area for research and development for educators in all fields. This paper shares the story of the development of an Australian Network for Vocational Education …

Bending Instability Of Electrically Charged Liquid Jets Of Polymer Solutions In Electrospinning, Darrell Hyson Reneker, Alexander L. Yarin, Hao Fong, Sureeporn Koombhongse

College of Polymer Science and Polymer Engineering

Nanofibers of polymers were electrospun by creating an electrically charged jet of polymer solution at a pendent droplet. After the jet flowed away from the droplet in a nearly straight line, it bent into a complex path and other changes in shape occurred, during which electrical forces stretched and thinned it by very large ratios. After the solvent evaporated, birefringent nanofibers were left. In this article the reasons for the instability are analyzed and explained using a mathematical model. The rheological complexity of the polymer solution is included, which allows consideration of viscoelastic jets. It is shown that the longitudinal …

Ac Susceptibility Of Sr3CuptXIr1-XO6: A Magnetic System With Competing Interactions And Dimensionality, S H. Irons, T D. Sangrey, K M. Beauchamp, M D. Smith, Hans Conrad Zur Loye

Faculty Publications

Sr₃CuPt_xIr_1-xO₆ has been cited as an example of a one-dimensional quantum spin chain with competing ferromagnetic and antiferromagnetic interactions. We have measured the ac susceptibility of Sr₃CuPt_xIr_1-xO₆ with x=0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, and 0.7, in magnetic fields of 0–60 kOe, and at temperatures down to 0.275 K. Our data show that the x=endpoint Sr₃CuIrO₆, exhibits long-range ferromagnetic order at T=20.1 K, contrary to results from dc susceptibility studies which indicated that it remained a one-dimensional ferromagnet to below 4 …
