Satisficing Applied To Simulated Soccer, Jay Packard Feb 2003

Satisficing Applied To Simulated Soccer, Jay Packard

Theses and Dissertations

Satisficing was introduced by the economist Herbert Simon to allow for decisions that are "good enough" when there are insufficient computational resources and knowledge to obtain the optimal outcome. Autonomous multi-agent systems often require such decision making because of the complexity and unknown factors present in such an environment. Satisficing has been extended significantly by Wynn Stirling. Through extended satisficing, he has departed from conventional approaches to autonomous multi-agent systems, based as they usually are on the assumption that each participant is motivated exclusively by its own self interest, and will therefore attempt to maximize its benefit, regardless of the …

Time Aliasing Methods Of Spectrum Estimation, Jason F. Dahl Feb 2003

Time Aliasing Methods Of Spectrum Estimation, Jason F. Dahl

Theses and Dissertations

Time aliasing methods of spectrum estimation alter the time representation of a signal for the purpose of improving its frequency domain representation. Time aliasing allows characteristics of longer time window functions to be used with shorter DFT length. Windows designed specifically for use with time aliasing have improved properties compared to conventional windows. Many previous uses of time aliasing, including overlap-and-add methods of digital filtering, have focused on the elimination of time aliasing effects in the frequency domain in order to improve the representation of reconstructed signals in the time domain and have not addressed the issues associated with spectrum …

Real Time Dynamic Trajectory Smoothing For Uninhabited Aerial Vehicles, Erik Anderson, Randal Beard, Timothy W. Mclain Feb 2003

Real Time Dynamic Trajectory Smoothing For Uninhabited Aerial Vehicles, Erik Anderson, Randal Beard, Timothy W. Mclain

Faculty Publications

Sponsorship: AFOSR, DARPA. This paper presents a real-time, feasible trajectory generation algorithm for unmanned air vehicles (UAVs) flying through a sequence of waypoints. The algorithm produces extremal trajectories that transition between straight-line path segments in a time-optimal fashion. In addition, the algorithm can be configured so that the dynamically feasible trajectory has the same path length as the straight-line waypoint path. Implementation issues associated with the algorithm are described in detail. Simulation studies show the effectiveness of the proposed method.

Tools And Metrics For Evaluating Modular Product Concepts Based On Strategic Objectives, Matthew Bailey Strong Jan 2003

Tools And Metrics For Evaluating Modular Product Concepts Based On Strategic Objectives, Matthew Bailey Strong

Theses and Dissertations

The design of modular products has recently become the focus of significant research in the area of design theory and methodology. This focus is the result of increased awareness of the potential power of modularity to achieve certain product objectives. However, there continues to be a gap between the results of academic research and industrial application. The refinement, consolidation, and extension of this academic research would help design teams who are charged with developing modular products to use these academic findings in real world, industrial applications. The research presented in this document focuses on developing design tools, based on past …

American Ships And Danish Immigrants In 1869, Harry R. Skallerup Jan 2003

American Ships And Danish Immigrants In 1869, Harry R. Skallerup

The Bridge

During the period between the end of the Civil War and the heightening of hostilities of the Franco-Prussian War in late 1870, American-built wooden paddle-wheel steamships played a competitive role in the expansion of transatlantic passenger traffic. The war, however, along with the ascendancy of propeller-driven ships with larger iron hulls and more efficient engines, led to their demise in this trade. But within the hiatus of the wars, 1869 stands out as the year in which the first direct, scheduled steamer departures from Copenhagen to New York were made. This service was provided by passenger steamers of U.S. registry …

A Spatial Technique For Estimating Streambank Rosion Based On Watershed Characteristics Jan 2003

A Spatial Technique For Estimating Streambank Rosion Based On Watershed Characteristics

Journal of Spatial Hydrology

A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This technique relies on the use of data sets that are easily obtained and expressed as GIS data layers. The basis of this technique are statistical relationships between “lateral erosion rates” and watershed characteristics such as curve number, grazing animal density, topographic slope, soil erodibility, and degree of urban development. An algorithm for estimating streambank erosion was incorporated into a GIS-based watershed model. Simulated and observed sediment loads were compared for twenty-eight …

For The Want Of Ten Dollars: The Development Of The Terra Cotta Industry In New Jersey, Thorvald Hansen Jan 2003

For The Want Of Ten Dollars: The Development Of The Terra Cotta Industry In New Jersey, Thorvald Hansen

The Bridge

When the Mathiasens, Karl and his father, left Thisted, on Denmark's northeast Jutland peninsula, for America in 1872, the intention of the elder Mathiasen was to go to Michigan where he had a sister living. When they arrived in New York the father totaled up the funds he had and discovered that the trip thus far had cost more than he expected. He lacked ten dollars of having enough to travel farther west. On the advice of a kindly Dane they walked the few miles to Perth Amboy, New Jersey where they were told they could probably find work. It …

Spatially Distributed Watershed Mapping And Modeling: Thermal Maps And Vegetation Indices To Enhance Land Cover And Surface Microclimate Mapping: Part 1 Jan 2003

Spatially Distributed Watershed Mapping And Modeling: Thermal Maps And Vegetation Indices To Enhance Land Cover And Surface Microclimate Mapping: Part 1

Journal of Spatial Hydrology

The extent and type of watershed cover affects the movement of water in the hydrologic cycle, thus accurate representation of the physical and biological features of the landscape within the watershed is required. Satellite imagery from Landsat and other satellites provide land cover and surface microclimate information with high temporal and spatial accuracy. The use of these data to understand hydrologic processes depends on how accurately they are interpreted and mapped. This paper utilizes the surface radiant temperatures derived from the thermal band of Landsat images and vegetation indices derived from visible, near-infrared, thermal and mid- infrared spectrums to further …

The "Unidentified Pioneers": An Analysis Of Staffordshire Mormons, 1837 To 1870, Stephen G. Arrowsmith Jan 2003

The "Unidentified Pioneers": An Analysis Of Staffordshire Mormons, 1837 To 1870, Stephen G. Arrowsmith

Theses and Dissertations

The evidence presented in this thesis advocates an increased level of scholarly interest in English working-class Mormon converts. To illustrate who these people were, and what their roles were as part of Mormon story, this regional study introduces and makes available over twelve hundred Staffordshire Mormons, and asks questions of the collected statistical information. The conservative Staffordshire Mormons clearly assisted the establishment, and continuation, off a Zion in the American West. Much of the data confirms previous scholarship; however, those with “differing visions” of Mormonism (for example, the RLDS Church) attracted Staffordshire converts in larger numbers than previously suggested. The …

“Nothing Less Than Miraculous” The First Decade Of Mormonism In Mongolia, Steven C. Harper Jan 2003

“Nothing Less Than Miraculous” The First Decade Of Mormonism In Mongolia, Steven C. Harper

BYU Studies

The Latter-day Saints' assumption of Christ's great commission—the command to teach and baptize all nations—can hardly be overstated as a motivational force for sending missionaries to far-away places to testify of the restored gospel of Jesus Christ. An 1831 revelation authorized and empowered Joseph Smith to send missionaries "unto the ends of the world" and "to lay the foundation of this church, and to bring it forth out of obscurity" (D&C 1:23, 30). What better manifestation could be found of the power of these words than the events of the first decade of Mormonism in Mongolia, perhaps the most obscure …

Spatially Distributed Watershed Mapping And Modeling: Gis-Based Storm Runoff Response And Hydroraph Analysis: Part 2 Jan 2003

Spatially Distributed Watershed Mapping And Modeling: Gis-Based Storm Runoff Response And Hydroraph Analysis: Part 2

Journal of Spatial Hydrology

Advances in scientific knowledge and new techniques of remote sensing permit a better understanding of the physical land features governing hydrologic processes, and make possible efficient, large-scale hydrologic modeling. The need for land-cover and hydrologic response change detection at a larger scale and at times of the year when hydrologic studies are critical makes satellite imagery the most cost effective, efficient and reliable source of data. In this work, remotely-sensed data and geographic information system (GIS) tools were used to estimate the changes in runoff response for three watersheds (Etonia, Econlockhatchee, and S-65A sub- basins) in Florida. Land-use information from …

Assessment Of The Impact Of Mining On Agricultural Land Using Erosion-Deposition Model And Space Borne Multispectral Data Jan 2003

Assessment Of The Impact Of Mining On Agricultural Land Using Erosion-Deposition Model And Space Borne Multispectral Data

Journal of Spatial Hydrology

Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa state, south-western India using the erosion-deposition model proposed by Mitasova et al. (1996). Information on various parameters of the model, namely curve number, management factor, cover factor, slope, soil erodibility, etc. was derived from the Indian Remote Sensing satellite (IRS-IC) Linear Image Self Scanning sensor LISS-III and PAN-merged data in conjunction with the DEM, field check and topographic maps at 1:25,000 scale. While only 11.2% …

A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts Jan 2003

A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts

Faculty Publications

This paper introduces memory-based learning as a viable approach for Cantonese tone recognition. The memorybased learning algorithm employed here outperforms other documented current approaches for this problem, which is based on neural networks. Various numbers of tones and features are modeled to find the best method for feature selection and extraction. To further optimize this approach, experiments are performed to isolate the best feature weighting method, the best class voting weights method, and the best number of k-values to implement. Results and possible future work are discussed.

High-Pressure Coal Pyrolysis In A Drop Tube Furnace, Koichi Matsuoka, Zhi-Xin Ma, Hiroyuki Akiho, Zhan-Guo Zhang, Akira Tomita, Thomas H. Fletcher, Marek A. Wojtowicz, Stephen Niksa

Faculty Publications

To obtain useful and reliable pyrolysis data under high pressures, continuous pyrolysis experiments were carried out using a drop tube furnace. To ascertain the reliability of data, a mass balance during pyrolysis was carefully checked. The pyrolysis data obtained in this equipment was compared with previous results, and it was found that the weight loss observed in the drop tube furnace was somewhat larger than those obtained with other apparatuses. The experimental results were compared with those predicted by three pyrolysis models. Although discrepancies between predictions and experimental results were observed under a certain condition, the agreement between the experimental …

A Vision System Performing Lip Shape Analysis For Speech Pathology Research, Christopher Dromey, D J. Lee, Daniel Bates, Xiaoqian Xu

Faculty Publications

We have built a machine vision system to perform lip shape analysis and recognition and to generate 3.D lip models for speech pathology research. The system employs two color cameras that are synchronized to capture image video pairs simultaneously. A novel color segmentation technique that converts the RGB color components to linear color space has been developed to extract lip shape contours. Lip shape of the viseme, the smallest visibly distinguishable unit of speech, is used to identify its corresponding image frame in the recorded image sequences. It is also used to reconstruct the 3-D lip shape model as a …

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause Jan 2003

Automated Rating Of Esl Essays, Deryle W. Lonsdale, Diane Strong-Krause

Faculty Publications

To date, traditional NLP parsers have not been widely successful in TESOLoriented applications, particularly in scoring written compositions. Re-engineering such applications to provide the necessary robustness for handling ungrammatical English has proven a formidable obstacle. We discuss the use of a nontraditional parser for rating compositions that attenuates some of these difficulties. Its dependency-based shallow parsing approach provides significant robustness in the face of language learners’ ungrammatical compositions. This paper discusses how a corpus of L2 essays for English was rated using the parser, and how the automatic evaulations compared to those obtained by manual methods. The types of modifications …
