Artificial Neural Network Application On Estimation Of Aquifer Transmissivity Jan 2008

Artificial Neural Network Application On Estimation Of Aquifer Transmissivity

Journal of Spatial Hydrology

The present study focuses on the unexplored area of application of artificial neural network in groundwater hydrology. Three models, each based on artificial neural networks, are applied for prediction of zonal transmissivity. These techniques can be considered as black box models that can predict output values for given range of input values after establishing an acceptable relation which is obtained by training the system. The study is based on coupling of Finite Element Method (FEM) - Artificial Neural Network (ANN) model, which serve as forward (FEM) and inverse (ANN) models. An inverse technique using ANN is considered for estimating parameters …

Extreme Rainfall Analysis And Estimation Of Probable Maximum Precipitation (Pmp) By Statistical Methods Over The Indus River Basin In India Jan 2008

Extreme Rainfall Analysis And Estimation Of Probable Maximum Precipitation (Pmp) By Statistical Methods Over The Indus River Basin In India

Journal of Spatial Hydrology

Annual extreme rainfall series of 1-3 day durations at stations located inside the Indus basin in India were subjected to statistical analysis in order to estimate point Probable Maximum Precipitation (PMP) and maximum rainfall of different return periods for the durations of 1-3 days. Daily rainfall data of 210 stations ranging from 1901-2000 (with varying data length) has been considered for the present study. Rainfall distribution of the basin on seasonal and annual scale has been examined. Spatial patterns of 1-3 day extreme rainfall over the basin have been presented which showed that low values of extreme rainfall are located …

Alphabetical Lives: Early Modern German Biographical Lexicons And Encyclopedias, Richard G. Cole Jan 2008

Alphabetical Lives: Early Modern German Biographical Lexicons And Encyclopedias, Richard G. Cole

Quidditas

Those who appear obvious to us as “major players” in past eras may in part result from an unintended consequence of the work of early modern biographical lexicographers. By the eighteenth century, there were enough printed sources and available archival materials to deluge or even overwhelm historians and biographers with information about past actors of sixteenth century history. Those biographical lexicographers made choices about whom to give prominence and whom to minimize or ignore in their works.

Adapting Adtrees For High Arity Features, Irene Langkilde-Geary, Robert Van Dam, Dan A. Ventura Jan 2008

Adapting Adtrees For High Arity Features, Irene Langkilde-Geary, Robert Van Dam, Dan A. Ventura

Faculty Publications

ADtrees, a data structure useful for caching sufficient statistics, have been successfully adapted to grow lazily when memory is limited and to update sequentially with an incrementally updated dataset. For low arity symbolic features, ADtrees trade a slight increase in query time for a reduction in overall tree size. Unfortunately, for high arity features, the same technique can often result in a very large increase in query time and a nearly negligible tree size reduction. In the dynamic (lazy) version of the tree, both query time and tree size can increase for some applications. Here we present two modifications to …

Socially Rational Models For Autonomous Agents, Wynn C. Stirling, James K. Archibald, Matthew S. Nokleby Jan 2008

Socially Rational Models For Autonomous Agents, Wynn C. Stirling, James K. Archibald, Matthew S. Nokleby

Faculty Publications

Autonomous multi-agent systems that are to coordinate must be designed according to models that accommodate such complex social behavior as compromise, negotiation, and altruism. In contrast to individually rational models, where each agent seeks to maximize its own welfare without regard for others, socially rational agents have interests beyond themselves. Such models require a new type of utility function a social utility to ensure three desirable properties: (a) conditional preferences agents may adjust their preferences to account for the preferences of others; (b) endogeny group preferences are determined internally by interactions between individual agents; (c) framing invariance reformulations of the …

Model-Centered Instruction, The Design, And The Designer, Andrew S. Gibbons Iii Jan 2008

Model-Centered Instruction, The Design, And The Designer, Andrew S. Gibbons Iii

Faculty Publications

A model of instruction described by Wenger (1987) identifies three elements that are active during instruction: the mental model the instructor wishes to share with the learner, the external experience used to communicate the mental model, and the evolving mental model of the learner. Gibbons (2003a), writing in response to Seel (2003), noted this three-part description as a bridge concept relating learning and instruction. This view has important practical implications for designers of instruction. For example, Gibbons and Rogers (in press) propose that there exists a natural layered architecture within instructional designs that corresponds with instructional functions. Among these layers …

What Does It Mean To Be A Christian?: The Views Of Joseph Smith And Soren Kierkegaard, David L. Paulsen Jan 2008

What Does It Mean To Be A Christian?: The Views Of Joseph Smith And Soren Kierkegaard, David L. Paulsen

BYU Studies

The Danish philosopher Søren Kierkegaard (1813-1855) and the American prophet Joseph Smith (1804-1844) both radically critiqued nineteenth-century Christian culture. Though Søren often directed critiques specifically toward the State Church of Denmark, his ultimate target was Christianity as a whole, or simply "Christendom." Joseph's critique singled out no specific church; he also focused on Christianity as a whole. Notwithstanding important differences, Paulsen finds Søren's and Joseph's critiques of nineteenth-century Christendom mutually reinforcing and illuminating. The comparison of Smith's and Kierkegaard's views includes the following ideas: (1) the New Testament church no longer existed, (2) Christian theology had become defiled, (3) the …

Selling The Soul Of Science For A Pot Of Message: Evangelizing Atheism In The God Delusion, Steven C. Walker Jan 2008

Selling The Soul Of Science For A Pot Of Message: Evangelizing Atheism In The God Delusion, Steven C. Walker

BYU Studies

Bestseller lists for the past two years chart a swelling tide of interest in a long-standing backwater: atheism. Nothing so tame as old-fashioned agnostic doubt, the new wave floods readers with outspoken scientific atheism. Sam Harris’s The End of Faith (2004) was the earthquake that triggered a tsunami swollen by urgent tributaries from Daniel C. Dennett’s Breaking the Spell: Religion as a Natural Phenomenon (2006) and Marc D. Hauser’s Moral Minds (2006), swelled all the more by Harris’s reprise Letter to a Christian Nation (2006). That atheist tidal wave has yet to crest—Carl Sagan hectors us from the grave in …

How Are Preferences Revealed?, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian Jan 2008

How Are Preferences Revealed?, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian

Faculty Publications

Revealed preferences are tastes that rationalize an economic agent's observed actions. Normative preferences represent the agent's actual interests. It sometimes makes sense to assume that revealed preferences are identical to normative preferences. But there are many cases where this assumption is violated. We identify five factors that increase the likelihood of a disparity between revealed preferences and normative preferences: passive choice, complexity, limited personal experience, third-party marketing, and intertemporal choice. We then discuss six approaches that jointly contribute to the identification of normative preferences: structural estimation, active decisions, asymptotic choice, aggregated revealed preferences, reported preferences, and informed preferences. Each …

Learning Policies For Embodied Virtual Agents Through Demonstration, Jonathan Dinerstein, Parris K. Egbert, Dan A. Ventura Jan 2008

Learning Policies For Embodied Virtual Agents Through Demonstration, Jonathan Dinerstein, Parris K. Egbert, Dan A. Ventura

Faculty Publications

Although many powerful AI and machine learning techniques exist, it remains difficult to quickly create AI for embodied virtual agents that produces visually lifelike behavior. This is important for applications (e.g., games, simulators, interactive displays) where an agent must behave in a manner that appears human-like. We present a novel technique for learning reactive policies that mimic demonstrated human behavior. The user demonstrates the desired behavior by dictating the agent’s actions during an interactive animation. Later, when the agent is to behave autonomously, the recorded data is generalized to form a continuous state-to-action mapping. Combined with an appropriate animation algorithm …

Sentiment Regression: Using Real-Valued Scores To Summarize Overall Document Sentiment, Adam Drake, Eric K. Ringger, Dan A. Ventura Jan 2008

Sentiment Regression: Using Real-Valued Scores To Summarize Overall Document Sentiment, Adam Drake, Eric K. Ringger, Dan A. Ventura

Faculty Publications

In this paper, we consider a sentiment regression problem: summarizing the overall sentiment of a review with a real-valued score. Empirical results on a set of labeled reviews show that real-valued sentiment modeling is feasible, as several algorithms improve upon baseline performance. We also analyze performance as the granularity of the classification problem moves from two-class (positive vs. negative) towards infinite-class (real-valued).

The Nahom Maps, James Gee Jan 2008

The Nahom Maps, James Gee

Journal of Book of Mormon Studies

Several maps from the seventeenth and eighteenth centuries support details of Lehi’s journey as recorded in the Book of Mormon. In 1751, the renowned cartographer Jean Baptiste Bourguignon D’Anville became the first to include Nahom (or Nehem), Ishmael’s burial place in the Book of Mormon, in his map of Asia. This map and a 1771 map of Yemen are the basis for most accurate maps of Arabia from 1751 to 1814. The spelling varies among the subsequent maps, with most using either D’Anville’s Nehem or Niebuhr’s Nehhm, but the location of Nahom does not differ between those maps that include …

The Poetics Of Paraphrase: The Positivist Postmodernism In Mikhail Gasparov’S “Experimental Translations”, Heinrich Kirschbaum Jan 2008

The Poetics Of Paraphrase: The Positivist Postmodernism In Mikhail Gasparov’S “Experimental Translations”, Heinrich Kirschbaum

Russian Language Journal

Two years before his death, Mikhail Gasparov (1935-2005) published his “Ėksperimental’nye perevody” (2003, “Experimental Translations,” or ETs), an anthology of translated works by authors from different time periods and literary traditions. The ETs are experimental in many ways: in some of his condensed translations, Gasparov shortens the originals drastically, in some cases by 80 percent. However, the ETs are not only experimental due to Gasparov’s new “technique of translation,” but also thanks to the choice of the originals to be translated. In addition to Hölderlin and Kavafis, Gasparov translates Pushkin and Lermontov from Russian to Russian, shortening and paraphrasing them …

Promoting Supportive Relationships In Youth Programs: A Self-Determination Theory Perspective, Mat D. Duerden, Ann Gillard Jan 2008

Promoting Supportive Relationships In Youth Programs: A Self-Determination Theory Perspective, Mat D. Duerden, Ann Gillard

Faculty Publications

Although research suggests that positive contact with nonparental adults is developmentally beneficial for youth; many adolescents do not have access to such relationships. It is important that adults structure existing relationships to optimize positive youth development. Relationships with adults, who support youth’s needs for autonomy, relatedness, and competence, provide youth with scaffolding as they navigate their way through adolescence. Self-Determination Theory offers a straight-forward approach to understanding the elements of contexts that best promote the development of supportive relationships. The purpose of this paper is to review the literature concerning youth-adult relationships, including their associated prevalence and developmental benefits across …

Alejandro Amenábar And The Embodiment Of Skepticism In ​Abre Los Ojos​, David Laraway Jan 2008

Alejandro Amenábar And The Embodiment Of Skepticism In ​Abre Los Ojos​, David Laraway

Faculty Publications

For most philosophers of the Anglo-American tradition, the problem of radical skepticism and its variants - i.e., the possibility that I could be massively mistaken in my beliefs about the external world, other minds, and even myself - no longer has the cachet itonce did. Although itmaintains a respectable place in contemporary epistemology it is clearly on the periphery of the discipline and no longer claims the attention once devoted to it by philosophers of the stature of Descartes, Hume, and Kant. Pride of place now goes, rather, to the task of naturalizing epistemology, which seeks to interpret questions about …

Time Reversal, Brian E. Anderson, Michele Griffa, Paul A. Johnson, Carene Larmat, Timothy J. Ulrich Jan 2008

Time Reversal, Brian E. Anderson, Michele Griffa, Paul A. Johnson, Carene Larmat, Timothy J. Ulrich

Faculty Publications

This article provides an historical overview of Time Reversal (TR), introduces its basic physics, addresses advantages and limitations, and describes some applications of this very active research area of acoustics. In the Geophysics Group at the Los Alamos National Laboratory, we conduct studies of TR of elastic waves in solids. Our work includes application of TR to nondestructive evaluation of materials, as well as to earthquake source characterization, and ground-based nuclear explosion monitoring. We emphasize the term elastic waves here to underscore that we include both compression and shear waves, in contrast to purely acoustic waves that are only compressional.

Automatic Composition Of Themed Mood Pieces, Heather Chan, Dan A. Ventura Jan 2008

Automatic Composition Of Themed Mood Pieces, Heather Chan, Dan A. Ventura

Faculty Publications

Musical harmonization of a given melody is a nontrivial problem; slight variations in instrumentation, voicing, texture, and bass rhythm can lead to significant differences in the mood of the resulting piece. This study explores the possibility of automatic musical composition by using machine learning and statistical natural language processing to tailor a piece to a particular mood using an existing melody.

Determining The Refractive Index In The Extreme Ultraviolet Using Kramers-Kronig On Thin-Film Scandium Oxide Transmission Data, David D. Allred, Jacqualine J. Butterfield Jan 2008

Determining The Refractive Index In The Extreme Ultraviolet Using Kramers-Kronig On Thin-Film Scandium Oxide Transmission Data, David D. Allred, Jacqualine J. Butterfield

Faculty Publications

Whereas the real part of the refractive index is dependent on both transmittance and reflectance, the imaginary part can be determined from transmittance data alone. It is possible to use Kramers-Kronig analysis to calculate the real part if the imaginary part is known over a sufficiently broad range. We show that the delta calculated from reflection and transmission data without taking into account roughness may underestimate the real part of the refractive index of the scandium oxide samples we are studying by up to 40% near 270 eV.

Nanoscale Characterization Of Thin Film Coatings Using Annular Dark Field Scanning Transmission Electron Microscopy, Guillermo Acosta, Richard Vanfleet, David D. Allred Jan 2008

Nanoscale Characterization Of Thin Film Coatings Using Annular Dark Field Scanning Transmission Electron Microscopy, Guillermo Acosta, Richard Vanfleet, David D. Allred

Faculty Publications

When considering the optical performance of thin films in the Extreme Ultraviolet (EUV), developing an accurate physical description of a thin film coating is necessary to be able to successfully model optical performance. With the short wavelengths of the EUV, film interfaces and sample roughness warrant special attention and care. The surfaces of thin film samples are routinely measured by Atomic Force Microscopy, from which roughness can be determined. However, characterizing the quality of interfaces below the surface is much more challenging. In a recent study of scandium oxide thin films, High Resolution Transmission Electron Microscopy and Annular Dark Field …

Utilizing Phrase-Similarity Measures For Detecting And Clustering Informative Rss News Articles, Yiu-Kai D. Ng, Maria Soledad Pera Jan 2008

Utilizing Phrase-Similarity Measures For Detecting And Clustering Informative Rss News Articles, Yiu-Kai D. Ng, Maria Soledad Pera

Faculty Publications

As the number of RSS news feeds continue to increase over the Internet, it becomes necessary to minimize the workload of the user who is otherwise required to scan through huge numbers of news articles to find related articles of interest, which is a tedious and often an impossible task. In order to solve this problem, we present a novel approach, called InFRSS, which consists of a correlation-based phrase matching (CPM) model and a fuzzy compatibility clustering (FCC) model. CPM can detect RSS news articles containing phrases that are the same as well as semantically alike, and dictate the degrees …

Reduced Order Modeling Of Time-Dependent Reflectance Profiles From Purely Scattering Media, R. Scott Larson, Matthew R. Jones Jan 2008

Reduced Order Modeling Of Time-Dependent Reflectance Profiles From Purely Scattering Media, R. Scott Larson, Matthew R. Jones

Faculty Publications

Due to the widespread existence and importance of foam, inverse techniques for characterizing industrial foams are of interest. An essential element in an inverse method used to characterize a foam layer is a model of the time-dependent reflectance of a laser pulse. Monte Carlo methods may be used to accurately model reflectance, but these methods are computationally expensive. Computationally efficient methods based on the diffusion approximation have been developed, but this approach is not sufficiently accurate in many cases of interest. Therefore, a computationally efficient and robust method is desirable. This paper presents a computationally efficient method for modeling the …

Diatom Species Composition And Ecology Of The Animas River Watershed, Colorado, Usa, Gerald V. Sgro, John B. Poole, Jeffery R. Johansen Dec 2007

Diatom Species Composition And Ecology Of The Animas River Watershed, Colorado, Usa, Gerald V. Sgro, John B. Poole, Jeffery R. Johansen

Western North American Naturalist

The diatom flora of selected sites in the Animas River Watershed, San Juan County, Colorado, was studied. Eighty diatom taxa were identified from 10 sites: 8 sites on the Animas River and 1 site each on the Cement and Cascade tributaries. The sample diatom abundance was dominated by Achnanthidium minutissimum, Encyonema silesiacum, Aulacoseira distans, Hannaea arcus, and Diatoma mesodon. The presence of teratologic specimens of Fragilaria and Achnanthidium in the samples indicated the possibility of metals contamination. Diatom diversity was low and Lange-Bertalot pollution index scores indicated little organic pollution evidenced from diatom composition. There …
