Second-Order Two-Dimensional Systems: Computing The Transfer Function, George E. Antoniou, Marinos T. Michael Dec 2004

Second-Order Two-Dimensional Systems: Computing The Transfer Function, George E. Antoniou, Marinos T. Michael

Department of Computer Science Faculty Scholarship and Creative Works

In this paper the discrete Fourier transform is used to determine the coefficients of a transfer function of a new two-dimensional model of second-order: x(i1 + 2, i2 + 2) = A0 x(i 1 + 1, i2 + 1) + A1x(i1 + 1, i 2) +A2x(i1, i2 + 1). The algorithm is straightforward and has been implemented using the software package Matlab™. Two step-by-step examples illustrating the application of the algorithm are presented. © 2004 FEI STU.

The Characterization Of Nanosized Nickel-Zinc Ferrites Synthesized Within Reverse Micelles Of Ctab/1-Hexanol/Water Microemulsion, Vuk Uskoković, Miha Drofenik, Irena Ban Dec 2004

The Characterization Of Nanosized Nickel-Zinc Ferrites Synthesized Within Reverse Micelles Of Ctab/1-Hexanol/Water Microemulsion, Vuk Uskoković, Miha Drofenik, Irena Ban

Pharmacy Faculty Articles and Research

Stoichiometric nanocrystalline nickel–zinc ferrites were synthesized by a reverse micelle method following a multi-microemulsion approach. Different pH values were chosen for the alkali precipitating reaction during the synthesis of different powders. Synthesized, as-dried and subsequently calcined powders were characterized in terms of their magnetic properties. XRD analyses and specific-surface area measurements were used to determine the average particle sizes of the synthesized samples. DCS and TGA measurements were performed to reveal the phase transitions within the samples at elevated temperatures, whereas TEM was used to view and record the microstructure of the nanosized ferrite samples. A possible mechanism of the …


Hydrologic And Geochemical Cycling Within Karst Versus Non-Karst Basins Within The Interior Low Plateau Province Of South-Central Kentucky, David Ek Dec 2004

Hydrologic And Geochemical Cycling Within Karst Versus Non-Karst Basins Within The Interior Low Plateau Province Of South-Central Kentucky, David Ek

Masters Theses & Specialist Projects

This thesis summarizes my research in which I investigated differences and characteristics in hydrologic, nutrient and geochemical cycling between karst versus nonkarst basins within the Interior Low Plateau Province. Field data including stream discharge, evapotranspiration, and dissolved major ion concentrations were collected for a period of one year for two basins within Mammoth Cave National Park. Twelve percent carbonate rocks underlie one basin, while the other consists of 48 percent carbonate rocks. The carbonate rock exposures within both basins exhibit karstification. The hydrologic and geochemical differences between these basins were compared to determine to what extent that cycles are modified …


Unconformities And Age Relationships, Tongue River And Older Members Of The Fort Union Formation (Paleocene), Western Williston Basin, U.S.A., Edward S. Belt, Joseph H. Hartman, John A. Diemer, Timothy J. Kroeger, Neil E. Tibert, H. Allen Curran Dec 2004

Unconformities And Age Relationships, Tongue River And Older Members Of The Fort Union Formation (Paleocene), Western Williston Basin, U.S.A., Edward S. Belt, Joseph H. Hartman, John A. Diemer, Timothy J. Kroeger, Neil E. Tibert, H. Allen Curran

Geosciences: Faculty Publications

An unconformable relationship is observed within the Paleocene Fort Union Formation in the western Williston Basin at the contact between the Tongue River Member and the underlying Lebo and Ludlow Members. Isotopic dates and pollen biozone data reported here are integrated with previously published data. A new correlation of these facies results in a revised history of localized depositional and tectonic events. One unconformity occurs at this lithological contact in the Pine Hills (PH), Terry Badlands (TB), and Ekalaka (E) areas west of the Cedar Creek anticline (CCA), and another unconformity occurs at the same lithological contact in the Little …

Discrete-Time Fractional Differentiation From Integer Derivatives, Hany Farid Dec 2004

Discrete-Time Fractional Differentiation From Integer Derivatives, Hany Farid

Computer Science Technical Reports

Discrete-time fractional derivative filters (1-D and 2-D) are shown to be well approximated from a small set of integer derivatives. A fractional derivative of arbitrary order (and, in 2-D, of arbitrary orientation) can therefore be efficiently computed from a linear combination of integer derivatives of the underlying signal or image.

On Shioda-Inose Structures Of One-Parameter Families Of K3 Surfaces, Ling Long Dec 2004

On Shioda-Inose Structures Of One-Parameter Families Of K3 Surfaces, Ling Long

Faculty Publications

We develop an algorithm to determine a one-parameter family of elliptic curves associated to a one-parameter family of K3 surfaces with generic Picard number 19 by a Shioda-Inose structure. The family of elliptic curves is determined up to an isomorphism and an isogeny. An application to a generalized congruence number problem is also discussed. © 2004 Elsevier Inc.

Prediction Of Crack Growth Rate And Load Interaction Effects Using Damage Accumulation Model, Virender Goswami Dec 2004

Prediction Of Crack Growth Rate And Load Interaction Effects Using Damage Accumulation Model, Virender Goswami

Masters Theses

In damage tolerant designs, it is important to know the crack growth behavior of a material, so that sudden failure of a component can be avoided by determining a safe life. There are numerous models available to predict the crack growth rate. Among them the "crack closure model" is most often used for predicting the crack growth rate for different R-ratios and load interaction effects. However recently, the crack closure model has come under criticism by many authors to be flawed and overrated owing to its inherent drawbacks.

Therefore, a mathematical model for the fatigue crack propagation based on damage …


Weir River Estuary: Land Protection Plan, Chantal Lefebvre, Michelle Portman Dec 2004

Weir River Estuary: Land Protection Plan, Chantal Lefebvre, Michelle Portman

Urban Harbors Institute Publications

If economic growth were the only measure of a community’s health and vitality, then the communities of Cohasset, Hingham, and Hull are fairing well. But this economic success is generally accompanied by changes in the physical landscape that can be unsettling for residents, especially when it means more development and expansion at the expense of culturally and socially important open space areas such as parks, woods, and marshes. The rapid pace and fragmented nature of such sprawling development gives communities little opportunity to come to terms with the long-term impacts, which in turn can lead to a sense of powerlessness …


Ways Of Being Singular: The Logic Of Individuality, Robert Berman Dec 2004

Ways Of Being Singular: The Logic Of Individuality, Robert Berman

Cardozo Public Law, Policy & Ethics Journal

The article explores Hegel's systematic logical account of individuality, arguing that it provides a foundational framework for understanding the concept through a set-theoretical interpretation. It identifies four conceptions of individuality—minimal, exclusivity, virtuosity, and novelty—and examines how Hegel's logic of individuality, as part of his broader philosophical system, offers a structured approach to reconciling these ideas. The article contends that the virtuosity model, which balances normative criteria with inclusivity, best aligns with Hegel's account, emphasizing the unity of universality and particularity in defining individuality.

Strict Feedforward Form And Symmetries Of Nonlinear Control Systems, Witold Respondek, Issa Amadou Tall Dec 2004

Strict Feedforward Form And Symmetries Of Nonlinear Control Systems, Witold Respondek, Issa Amadou Tall

Miscellaneous (presentations, translations, interviews, etc)

We establish a relation between strict feedforward form and symmetries of nonlinear control systems. We prove that a system is feedback equivalent to the strict feedforward form if and only if it gives rise to a sequence of systems, such that each element of the sequence, firstly, possesses an infinitesimal symmetry and, secondly, it is the factor system of the preceding one, i.e., is reduced from the preceding one by its symmetry. We also propose a strict feedforward normal form and prove that a smooth strict feedforward system can be smoothly brought to that form.


Weighted Canonical Forms Of Nonlinear Single-Input Control Systems With Noncontrollable Linearization, Issa Amadou Tall, Witold Respondek Dec 2004

Weighted Canonical Forms Of Nonlinear Single-Input Control Systems With Noncontrollable Linearization, Issa Amadou Tall, Witold Respondek

Miscellaneous (presentations, translations, interviews, etc)

We propose a weighted canonical form for single-input systems with noncontrollable first order approximation under the action of formal feedback transformations. This weighted canonical form is based on associating different weights to the linearly controllable and linearly noncontrollable parts of the system. We prove that two systems are formally feedback equivalent if and only if their weighted canonical forms coincide up to a diffeomorphism whose restriction to the linearly controllable part is identity.


The Road Not Yet Traveled: Why The Fcc Should Issue Digital Must-Carry Rules For Public Television "First", Andrew D. Cotlar Dec 2004

The Road Not Yet Traveled: Why The Fcc Should Issue Digital Must-Carry Rules For Public Television "First", Andrew D. Cotlar

Federal Communications Law Journal

After having recently adopted a variety of complex decisions concerning the digital television transition, the Federal Communications Commission ("FCC") may be poised in the next year to address the issue of mandatory cable carriage of digital broadcast television signals. In this regard, it may reasonably consider the possibility of crafting digital carriage rules for public television stations first without ruling positively or negatively on carriage of commercial stations. This action may legitimately be based on the unique legislative and factual differences between the noncommercial and commercial service and would be constitutionally permissible. This Article sets forth the legal basis for …


The Rotundity Of Large Planetary Objects, Adesanwo Moradeyo Dec 2004

The Rotundity Of Large Planetary Objects, Adesanwo Moradeyo

Graduate Student Papers (Physics)

The most obvious structural feature of planetary bodies is their roundness. This arises because of the dominate roles of the two effects of gravity and case of the deformation of matter, whether gas, liquid or solid. This project is about proving and solving out the time scale (τ ) of flow restoring the body to spherical shape when we consider a slightly deformed self-gravitating sphere and also checking for spherical of different planetary objects.


Slope Stability Analysis Of A Lake Michigan Coastal Bluff, Gregory Carlton Young Dec 2004

Slope Stability Analysis Of A Lake Michigan Coastal Bluff, Gregory Carlton Young

Masters Theses

Bluff failure along the Lake Michigan coast can be produced primarily by increased pore pressure from perched water tables above lacustrine clay deposits. To test this theory, a site in Allegan County, Michigan with alternating layers of sand, clay and glacial till was chosen for bluff failure monitoring. Historically, the site experiences sporadic massive failures as opposed to neighboring sites that show more regular and uniform displacements. Four pole and cable monitoring lines were measured bi-weekly from December 2001 to October 2003. Lake levels were low and no erosion of material at the base of the slope occurred. Slumps above …
