Embedded Training For Complex Information Systems, Brant A. Cheikes Jan 1999

Embedded Training For Complex Information Systems, Brant A. Cheikes

Computer Science: Faculty Publications

One approach to providing affordable operator training in the workplace is to augment applications with intelligent embedded training systems (ETS). Intelligent embedded training is highly interactive: trainees practice realistic problem-solving tasks on the prime application with guidance and feedback from the training system. This article makes three contributions to the theory and technology of ETS design. First, we describe a framework based on Norman’s “stages of user activity” model for defining the instructional objectives of an ETS. Second, we demonstrate a non-invasive approach to instrumenting software applications, thereby enabling them to collaborate with an ETS. Third, we describe a method …

Soliton Stability In A Z (2) Field Theory, J. J. P. Veerman, D. Bazeia, Fernando Moraes Jan 1999

Soliton Stability In A Z (2) Field Theory, J. J. P. Veerman, D. Bazeia, Fernando Moraes

Mathematics and Statistics Faculty Publications and Presentations

We investigate the stability of the coupled soliton solutions of a two-component Z(2) vector fieldmodel, in contraposition to similar solutions of a Z(2)×Z(2)model recently introduced. We demonstrate that the coupled soliton solutions of the Z(2) model are classically unstable.


Geometrical Models For Grain Dynamics, Giovani L. Vasconcelos, J. J. P. Veerman Jan 1999

Geometrical Models For Grain Dynamics, Giovani L. Vasconcelos, J. J. P. Veerman

Mathematics and Statistics Faculty Publications and Presentations

We study models for the gravity-driven, dissipative motion of a single grain on an inclined rough surface. Imposing some conditions on the momentum loss due to the collisions between the particle and the surface, we arrive at a class of models in which the grain dynamics is described by one-dimensional maps. The dynamics of these maps is studied in detail. We prove the existence of various dynamical phases and show that the presence of these phases is independent of the restitution law (within the class considered).

Electron Liquid Beyond The Random Phase Approximation, Mehmet Tomak, Ceyhun Bulutay Jan 1999

Electron Liquid Beyond The Random Phase Approximation, Mehmet Tomak, Ceyhun Bulutay

Turkish Journal of Physics

A deeper understanding of low-dimensional and small-scale electronic systems requires an accurate characterization of the many-electron effects. Based on the electron liquid (EL) model, these many-body effects in the three-dimensional (3D) and two-dimensional (2D) electronic systems are dealt going beyond the random phase approximation within the zero-temperature framework. The dielectric formulation of the many-body problem is recapitulated and the longitudinal dielectric function of the EL is obtained using the self-consistent local-field correction scheme, known as STLS, under a general spin-valley degeneracy. Extensive explicit expressions are provided for the use of other researchers. The performance of this formalism is compared in …


Magnetic Excitations In Random Anisotropic Magnets, İbrahim Avgin Jan 1999

Magnetic Excitations In Random Anisotropic Magnets, İbrahim Avgin

Turkish Journal of Physics

A study is made for the magnetic excitations and their Anderson localization properties for a Heisenberg ferromagnet with random anisotropic fields. The system is assumed to be in a strong applied field so that complete spin alignment is established. The magnetic excitations, i.e., the harmonic spin waves, are computed using coherent-field-anisotropy approximation (a version of coherent potential approximation of the electronic problem). The spin wave shift and damping are calculated using the computed coherent field which is a complex function of energy approximating the random medium as a mean field level. The localizaton of the excitations are calculated by adopting …

Three-Channel General-Purpose Astrophotometer, Romualdas Kalytis

Turkish Journal of Physics

The high-speed three-channel photometer suitable for the time-series observations of the "Whole Earth Telescope" (WET) project as well as for multicolor photometry is described. The photometer, designed for the Capodimonte Astronomical Observatory, Italy, is the latest version of the WET photometers developed by the WET group of Vilnius University since 1992. The main optical and mechanical layouts of the optico-mechanical module as well as the block-diagram of electronics are presented. The main specifications of the photometer expected after its completion are given.


Photometric Imaging With Distributive Solar Analogy, Zeki̇ Eker Jan 1999

Photometric Imaging With Distributive Solar Analogy, Zeki̇ Eker

Turkish Journal of Physics

The importance of DSA (Distributive Solar Analogy) when modeling starspots from a photometric data is discussed. It's advantage over the other modeling techniques to confine the solution parameters, especially the spot latitudes are described. Unlike the other photometric techniques which tries to locate limited number of cool surface spots, DSA aims to model global distribution of all virtually existing spots.

What Is The Common Good, And Why Does It Concern The Client's Lawyer?, John M. Finnis Jan 1999

What Is The Common Good, And Why Does It Concern The Client's Lawyer?, John M. Finnis

Journal Articles

Why is anything of real concern to any of us? Because, besides our simply emotional motives, we have reasons for action (which may be supported or opposed by our emotions). What are reasons for action? Some are instrumental, means to further ends: I have reason to start reading this paper to you, and you had reason to come back into the room to hear it. What reasons? Well, doing so is my contribution to this symposium's reflection on its subject-matter. That reflection, in turn, is intended to be instrumental in promoting a wider and deeper understanding of an important set …


Methods In Historical Ecology: A Case Study Of Tintic Valley, Utah, Jeffrey A. Creque, Neil E. West, James P. Dobrowolski Jan 1999

Methods In Historical Ecology: A Case Study Of Tintic Valley, Utah, Jeffrey A. Creque, Neil E. West, James P. Dobrowolski

Wildland Resources Faculty Publications

Through use of repeat photography, archival research, and field observation to reconstruct landscape vegetation patterns and changes across a 120 year period in the upper Tintic Valley of central Utah, researchers found significant changes in landscape vegetation pattern over time, including change in pinyon-juniper woodland area. Previously reported massive woodland harvest associated with early mining, domestic and agricultural activities elsewhere in the Intermountain West also took place in Utah. The impact on woodland area of the agricultural "bull" fence alone was significant. More recent study area woodland expansion also occurred. Because intensive industrial activity associated with development of the Tintic …

Creating A New University Through Object Oriented Enterprise Modeling: A Study Of Communications Knowledge Management & Distributed Cognition, Armando A. Arias Jr., Beryl L. Bellman

SSGS Faculty Publications and Presentations

Enterprise based object oriented (OO) and Unified Modeling Language (UML) modeling makes it possible to build the needed visual environments to organize people, technologies and activities (Arias, 1999d). In our modeling approach, the focus is on "things and relationships between things" described in commonly used terms. The modeling software bridges the so-called "semantic gap" between the people and the computer language (Booch, Rumbaugh & Jacobson, 1999). An object can be a product, a process, a person, a team, a company, an application or the inter-relationship between other objects. Objects can be pictured on the screen as maps formed by personalized …


Measuring The Diameter Of Your Blind Spot, Jeff Sanny Jan 1999

Measuring The Diameter Of Your Blind Spot, Jeff Sanny

Physics Faculty Works

A simple experiment to determine the diameter of the blind spot is described. Students are divided into groups of three and work together to perform the experiment. The procedure takes about 15 minutes and seems to be quite enjoyable to the class.


Mach’S Principle In A Mixed Newton-Einstein Context, Evert Jan Post, Michael Berg Jan 1999

Mach’S Principle In A Mixed Newton-Einstein Context, Evert Jan Post, Michael Berg

Mathematics, Statistics and Data Science Faculty Works

A closed physical space, in conjunction with scalar versus pseudo scalar distinctions, and an accordingly adapted Gauss theorem, reveal unexpected perspectives on Mach's principle, the mass-energy theorem, and a bonus insight into the nature of the solutions of the Einstein field equations of gravity.


Finite Type Link Homotopy Invariants, Blake Mellor Jan 1999

Finite Type Link Homotopy Invariants, Blake Mellor

Mathematics, Statistics and Data Science Faculty Works

Bar-Natan used Chinese characters to show that finite type invariants classify string links up to homotopy. In this paper, I construct the correct spaces of chord diagrams and Chinese characters for links up to homotopy. I use these spaces to show that the only rational finite type invariants of link homotopy are the pairwise linking numbers of the components.

Camera Trackers, Matthew Cutts Jan 1999

Camera Trackers, Matthew Cutts

Link Foundation Modeling, Simulation and Training Fellowship Reports

Tracking an object's location with inertial sensors works well over short time periods, but sensor drift and errors in integration cause errors to accumulate exponentially. Images, in contrast, work very well to determine a camera's location provided that the camera moves slowly. I received fellowship funding to work on a hybrid image and inertial tracker. The idea was to use data from the image sensors to correct errors and drift in the inertial sensors. The computer vision community has expended a great deal of energy in pursuing motion tracking from images. This area of research is also related to compositing …
