Numerical Solution Of Fractional Advection-Dispersion Equation, Zhi Qiang Deng, Vijay P. Singh, Lars Bengtsson

Faculty Publications

Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick's first law. Employing 74 sets of dye test data measured on natural streams, it is found that the fractional order F of the partial differential operator acting on the dispersion term varies around the most frequently occurring value of F=1.65 in the range of 1.4 to 2.0. Two series expansions are proposed for approximation of the limit definitions of fractional derivatives. On this ground, two three-term finite-difference schemes - "1.3 Backward Scheme"having the first-order accuracy and "F.3 Central Scheme"possessing the …

Simulations Of The Influence Of The West Caribbean Sea Circulation And Eddies On The Meso-American Barrier Reef System, Tal Ezer, Deeptha V. Thattai, Björn Kjerve

CCPO Publications

The Meso-American Barrier Reef System (MBRS) along the coasts of Mexico, Belize, Guatemala, and Honduras is an ecologically and biologically sensitive region. It provides for example, major spawning aggregation sites for various species of fish; these activities may be influenced by variations of the flow near the reef and the transports between the MBRS and the Caribbean Sea circulation. Caribbean eddies, which may play an important role in flow variability, have been studied in the past by observations and models (Carton and Chao, 1999; Murphy et al., 1999; Andrade and Barton, 2000; Oey et al., 2003), but knowledge of their …

A Modelling Study Of The Influence Of Environment And Food Supply On Survival Of Crassostrea Gigas Larvae, Eileen E. Hofmann, Eric N. Powell, Eleanor A. Bochenek, John M. Klinck

CCPO Publications

A biochemically based model was developed to simulate the growth, development, and metamorphosis of larvae of the Pacific oyster (Crassostrea gigas). The unique characteristics of the model are that it: (1) defines larvae in terms of their protein, neutral lipid, polar lipid, carbohydrate, and ash content; (2) tracks weight separately from length to follow larval condition; and (3) includes genetic variation in growth efficiency and egg quality to better simulate cohort population dynamics. The model includes parameterizations for filtration, ingestion, and respiration, which determine larval growth rate, and processes controlling larval mortality and metamorphosis. Changes in larval tissue …

Lagrangian Modelling Studies Of Antarctic Krill (Euphausia Superba) Swarm Formation, Eileen E. Hofmann, A. G. Edward Haskell, John M. Klinck, Cathy M. Lascara

CCPO Publications

A two-dimensional Lagrangian particle model was developed to examine the spatial distribution of Antarctic krill (Euphausia superba). The time-dependent location of particles, which represent krill individuals, is determined by random diffusion, foraging activity, and movement induced by the presence of neighbours. Foraging activity is based on prescribed food conditions and is such that krill swim slower and turn more frequently in areas of high food concentration. The presence or absence of neighbours either disperses krill, if the local concentrations become too dense, or coalesces krill, if concentrations become too dilute, respectively. Predation on krill is included and affects …

Satellite Evidence Of Hurricane-Induced Phytoplankton Blooms In An Oceanic Desert, S. M. Babin, J. A. Carton, T. D. Dickey, J. D. Wiggert

CCPO Publications

The physical effects of hurricanes include deepening of the mixed layer and decreasing of the sea surface temperature in response to entrainment, curl-induced upwelling, and increased upper ocean cooling. However, the biological effects of hurricanes remain relatively unexplored. In this paper, we examine the passages of 13 hurricanes through the Sargasso Sea region of the North Atlantic during the years 1998 through 2001. Remotely sensed ocean color shows increased concentrations of surface chlorophyll within the cool wakes of the hurricanes, apparently in response to the injection of nutrients and/or biogenic pigments into the oligotrophic surface waters. This increase in post-storm …

Gender Assignment To English Words In The Spanish Of Southern Arizona, Elise M. Dubord

Faculty Work

This paper examines the gender assignment of English words in the Spanish of Southern Arizona based on the categories of biological sex, phonological gender, and analogical gender. It is determined that biological sex is the greatest indicator of gender assignment, followed by phonological gender and lastly by analogical gender. There was a small (7.9%) proportion of variation in gender assignment to English words in the corpus that is attributed to a combination of words that are neither phonologically nor socially integrated into the Spanish lexicon and the linguistic insecurity of the participants.

Apes, Darwinian Continuity, And The Law, Roger S. Fouts

Animal Law Review

This article proposes that the delusional worldview that “man” is outside and above the other “defective” organic beings in nature is completely without empirical scientific foundation. An alternative and harmonious way of being is presented that is derived from the acceptance of the biological reality of continuity.

Redefining The Family: Undermining The Family, John Dewitt Gregory

Hofstra Law Faculty Scholarship

This essay examines the way in which legal academic commentators, particularly family law teachers and scholars, have urged that family be redefined, rejecting the conventional and traditional definitions to which courts and legislatures have generally adhered. Self-styled progressive scholars argue that currently prevailing doctrine arbitrarily excludes many deserving suitors from the recognition and protection afforded to families under state and constitutional law. The arguments in this essay reject such assertions, pointing out that new and expansive definitions of family either ignore or refuse to accept long standing precedents, including decisions of the United States Supreme Court, that for some three-quarters …

Darfur And The Rhetoric Of Genocide, Beth Van Schaack

Faculty Publications

The ancient concept of humanitarian intervention has become the subject of renewed debate and discussion at the inter-governmental level, within the non-governmental sector, and in the academy. This concept can be defined as the intervention into the territorial state by another state or a collective of states, with or without authorization from the United Nations Security Council, for the promotion or protection of basic human rights where the territorial state is perpetuating abuses or is unable or unwilling to provide the necessary protection to its inhabitants. Although intrigued by the concept in theory, interested parties are grappling with the specifics …

Aim: Automatically calibrate ICP Dynamic model to a specific patients.

Method: Use optimization algorithm to estimate parameter values (ICP, compliances, resistances) that minimize the squared error in predicted ICP.

Results: Estimated parameter values are plausible and improve predicted ICP. Optimization time for 18 minute episode = 2.5 min. for 1 parameter, 10 to 200 min. for multiple simultaneous parameters (too long).

A Comparison Of System Dynamics And Agent-Based Simulationapplied To The Study Of Cellular Receptor Dynamics, Wayne W. Wakeland, Edward J. Gallaher, Louis Macovsky, C. Athena Aktipis

Complex Systems Faculty Publications and Presentations

Cellular receptor dynamics are often analyzed using differential equations, making system dynamics (SD) a candidate methodology. In some cases it may be useful to model the phenomena at the biomolecular level, especially when concentrations and reaction probabilities are low and might lead to unexpected behavior modes. In such cases, agent-based simulation (ABS) may be useful. We show the application of both SD and ABS to simulate non-equilibrium ligand-receptor dynamics over a broad range of concentrations, where the probability of interaction varies from low to very low. Both approaches offer much to the researcher and are complementary. We did not find …

Directed Extended Dependency Analysis For Data Mining, Thaddeus T. Shannon, Martin Zwick

Complex Systems Faculty Publications and Presentations

Extended dependency analysis (EDA) is a heuristic search technique for finding significant relationships between nominal variables in large data sets. The directed version of EDA searches for maximally predictive sets of independent variables with respect to a target dependent variable. The original implementation of EDA was an extension of reconstructability analysis. Our new implementation adds a variety of statistical significance tests at each decision point that allow the user to tailor the algorithm to a particular objective. It also utilizes data structures appropriate for the sparse data sets customary in contemporary data mining problems. Two examples that illustrate different approaches …

A Comparison Of Modified Reconstructability Analysis And Ashenhurst‐Curtis Decomposition Of Boolean Functions, Anas Al-Rabadi, Marek Perkowski, Martin Zwick

Complex Systems Faculty Publications and Presentations

Modified reconstructability analysis (MRA), a novel decomposition technique within the framework of set‐theoretic (crisp possibilistic) reconstructability analysis, is applied to three‐variable NPN‐classified Boolean functions. MRA is superior to conventional reconstructability analysis, i.e. it decomposes more NPN functions. MRA is compared to Ashenhurst‐Curtis (AC) decomposition using two different complexity measures: log‐functionality, a measure suitable for machine learning, and the count of the total number of two‐input gates, a measure suitable for circuit design. MRA is superior to AC using the first of these measures, and is comparable to, but different from AC, using the second.

State-Based Reconstructability Analysis, Martin Zwick, Michael S. Johnson

Complex Systems Faculty Publications and Presentations

Reconstructability analysis (RA) is a method for detecting and analyzing the structure of multivariate categorical data. While Jones and his colleagues extended the original variable‐based formulation of RA to encompass models defined in terms of system states, their focus was the analysis and approximation of real‐valued functions. In this paper, we separate two ideas that Jones had merged together: the “g to k” transformation and state‐based modeling. We relate the idea of state‐based modeling to established variable‐based RA concepts and methods, including structure lattices, search strategies, metrics of model quality, and the statistical evaluation of model fit for analyses based …
