Teaching Content Creation With Programming, Phillip J. Mckerrow
Teaching Content Creation With Programming, Phillip J. Mckerrow
Faculty of Informatics - Papers (Archive)
Multimedia is an art form that uses computers as a means of personal expression. However, much multimedia content is unattractive, and many applications have poor user interfaces because many developers don't have training in both programming and content creation. To counteract this, we teach students QuickTime for Java, which provides a rich library for manipulating media. Our students reported an increased understanding of multimedia programming and developed creative skills.
Bitstream Binding Language – Mapping Xml Multimedia Containers Into Streams, Joseph Thomas-Kerr, I. Burnett, Philip Ciufo
Bitstream Binding Language – Mapping Xml Multimedia Containers Into Streams, Joseph Thomas-Kerr, I. Burnett, Philip Ciufo
Faculty of Informatics - Papers (Archive)
Bitstream Binding Language (BBL) provides an abstraction layer between XML multimedia containers and the way their resources and metadata are published in a bitstream. It allows multiple bindings from a single source document to facilitate interoperability and applicability of the multimedia content to a wide range of terminals and users. BBL introduces a number of features not found in other XML fragmentation techniques – such as support for random-access – and provides a highly general framework for combining metadata with multimedia content in a transport format. This paper presents an overview of BBL and provides details of a Java implementation …

A Convergence Theorem For Continued Fractions Of The Form K_{N=1}^{\Infty}A_{N}/1, James Mclaughlin, Nancy Wyshinski
Mathematics Faculty Publications
In this paper we present a convergence theorem for continued fractions of the form K∞n=1an/1. By deriving conditions on the an which ensure that the odd and even parts of K∞n=1an/1 converge, these same conditions also ensure that they converge to the same limit. Examples will be given.

Effects Of Sunlight On Decomposition Of Estuarine Dissolved Organic C, N And P And Bacterial Metabolism, Sl Mccallister, Je Bauer, J Kelly, Hw Ducklow
VIMS Articles
The effects of natural sunlight and microbial decomposition on DOC, DON, and DOP were investigated along the salinity gradient of a temperate coastal plain estuary. The impact of sunlight-irradiated DOM on bacterial properties (bacterial abundance, production, bacterial growth efficiency [BGE]) was also followed. Surface-water light levels resulted in no detectable abiotic production of NH4+ or PO43- or loss of DOC. Bacterial decomposition of DOC was enhanced by 27 to 200 % in irradiated relative to dark treatments. There was, however, no corresponding enhancement in DON and DOP remineralization. Significant differences in bacterial decomposition of light-exposed DOC were frequently observed following …

Melting Temperature Of Ice IH Calculated From Coexisting Solid-Liquid Phases, J. Wang, S. Yoo, Jaeil Bai, James R. Morris, Xiao Cheng Zeng
Melting Temperature Of Ice IH Calculated From Coexisting Solid-Liquid Phases, J. Wang, S. Yoo, Jaeil Bai, James R. Morris, Xiao Cheng Zeng
Xiao Cheng Zeng Publications
The purpose of this paper is twofold: (1) to compute the melting temperature (Tm) of ice Ih with both TIP4P and TIP5P models by using the two-phase coexistence method and to compare with previously obtained Tm; (2) to compute the Tm using recently improved TIP4P and TIP5P models, namely, the TIP4P-Ew (Ref. 6) and TIP5P-Ew (Ref. 7) models. Both models are developed specifically for use with Ewald techniques. The TIP4P-Ew model, in particular, has shown substantial improvement over the original TIP4P model as it can reproduce the density maximum at about 274 K, …
Three-Coulomb-Wave Pluvinage Model For Compton Double Ionization Of Helium In The Region Of The Cross-Section Maximum, S. Jones, Joseph H. Macek, Don H. Madison
Three-Coulomb-Wave Pluvinage Model For Compton Double Ionization Of Helium In The Region Of The Cross-Section Maximum, S. Jones, Joseph H. Macek, Don H. Madison
Physics Faculty Research & Creative Works
Double ionization of ground-state helium by the Compton scattering of a photon is calculated using the well-known product of three Coulomb waves (3C) wave function for the final double-continuum state of the atom and the Pluvinage wave function for the initial ground state (also a product of three Coulomb waves). The theoretical model fails to predict both the shape and the overall magnitude of the observed integrated cross section vs. Incident-photon energy. However, when the monopole part of the electron-photon interaction is removed by an ad hoc procedure, qualitative agreement is obtained, although the absolute size of the cross section …

How Much You Watch, How Much You Pay, Yongdong Wu, Hwee Hwa Pang, Robert H. Deng
Research Collection School Of Computing and Information Systems
This paper presents a pay-video scheme that manages video stream, key stream and payment stream efficiently. In our scheme, the owner segments a video into fragments and encrypts them with independent keys. The keys are generated with a novel concept called as hash interval, where each hash interval discloses a range of numbers without disclosing any information on numbers outside of the range. The video fragments are then broadcast on one or more channels. A buyer can purchase the keys to decrypt any fragments and, within each fragment, any desired quality level. The accompanying payment protocol is integrated with the …

All HMC Faculty Publications and Research
A general method for computing harmonic generation in reflection and transmission from planar nonmagnetic multilayer structures is described. The method assumes plane waves and treats harmonic generation in the parametric approximation. The method is applied in studying the second- and third-harmonic generation properties of thin crystal silicon layers surrounded by thermal oxide. Most independent components of the nonlinear susceptibility tensor have unique signatures with silicon layer thickness d, allowing their strength to be determined in principle by measuring harmonic generation as a function of d. Surface and bulk contributions to third-harmonic generation are cleanly distinguished, with the bulk signal dominating. …
The Design And Synthesis Of Novel Chaetomellic Acid A Analogues, Mark F. Mechelke, Jacquelyn C. Webb, Jessica L. Johnson
The Design And Synthesis Of Novel Chaetomellic Acid A Analogues, Mark F. Mechelke, Jacquelyn C. Webb, Jessica L. Johnson
Chemistry Faculty Publications
Chaetomellic acid A is an alkyl dicarboxylic acid isolated from the fermentation of Chaetomella acutiseta. Chaetomellic acid A has been shown to be a potent, highly specific inhibitor of RAS farnesyl protein transferase (FPTase). The association between RAS proteins and cancer has made chaetomellic acd A a potential chemotherapeutic agent. Two novel chaetomellic acid A analogues have been prepared that incorporate aromoatic rings in the alkyl tail. It is anticipated that these compounds will bind more tightly to the FPTase active site than the natural product due to intermolecular interactions between the aromatic rings in the tail and the …
Some Effective Diophantine Results Over Q-Bar, Lenny Fukshansky
Some Effective Diophantine Results Over Q-Bar, Lenny Fukshansky
CMC Faculty Publications and Research
In his 1999 paper D. W. Masser talks about effective search bounds for polynomial equations over integers and rationals. This discussion can also be extended over number fields. Unfortunately, as illustrated by Matiasevich's negative answer to Hilbert's 10-th problem, search bounds in general probably do not exist. Some special cases are understood, but in general very little is known. I will talk about effective search bounds for solutions of polynomial equations over Q-bar with some additional arithmetic conditions. This discussion also naturaly ties into the realm of "absolute" diophantine results, like Siegel's lemma of Roy and Thunder. I will try …
Water Quality Trading: What Can We Learn From 10 Years Of Wetland Mitigation Banking?, Eric Raffini, Morgan Robertson
Water Quality Trading: What Can We Learn From 10 Years Of Wetland Mitigation Banking?, Eric Raffini, Morgan Robertson
United States Environmental Protection Agency: Publications
In 2003 the U.S. Environmental Protection Agency issued its Water Quality Trading Policy. Water quality trading allows facilities facing high pollution-control costs to meet their regulatory requirements by purchasing environmentally equivalent or superior pollution reductions from another source, often at a lower cost. The policy, which hopes to achieve "water quality and environmental benefits greater than would otherwise be achieved under more traditional regulatory approaches," established the ground rules for trading and encourages states, interstate agencies, and tribes to develop and implement water quality trading programs for nutrients, sediments, and other pollutants. The policy generated controversy among some stakeholder groups; …

Section 1 provides a brief overview of the project, including a cursory summary of the history of the “Garrison Diversion” and how that history relates to this work focused on the analysis of risks and consequences potentially associated with interbasin biota transfers. The present study was initiated under the auspices of the Dakota Water Resources Act (DWRA) of 2000, which directed the Secretary of the Interior to conduct a comprehensive study of the water quality and quantity needs of the Red River Valley and the options for meeting those needs. As such, the Bureau of Reclamation (Reclamation) requested technical support …

Tetracycline is widely used as a biomarker for bait consumption by wildlife; tetracycline is incorporated into bones and teeth and can be detected by fluorescence microscopy several weeks postconsumption. During 2003, the United States Department of Agriculture distributed more than 10 million tetracycline-containing rabies-vaccine baits to control the spread of wildlife vectored rabies to humans, pets, and livestock. To estimate the percentage of target species consuming the baits, raccoons and skunks were collected in baited areas and teeth were analyzed for the presence of the biomarker. Several incidents of low biomarker detection rates prompted an investigation of the stability of …

Radiative Neutron Β-Decay In Effective Field Theory, Susan Gardner, Véronique Bernard, Ulf-G. Meißner, Chi Zhang
Center for Plant Science Innovation: Faculty and Staff Publications
In summary, we have computed the photon energy spectrum and photon polarization in neutron radiative β-decay in an effective field theory approach, utilizing HBCHPT and the SSE, including all terms in O(1/M). The leading contribution to the photon energy spectrum has been calculated previously [4]; we agree with the expression in Ref. [4] for Σspins |M|2, though we disagree with their numerical results for the photon energy spectrum. Moreover, we find that the O(1/M) terms are numerically quite small, generating contributions no larger than O(0.5 %), so that radiative neutron β-decay is quite insensitive to nucleon structure …

A Modular Approach To Document Indexing And Semantic Search, Dhanya Ravishankar, Krishnaprasad Thirunarayan, Trivikram Immaneni
Kno.e.sis Publications
This paper develops a modular approach to improving effectiveness of searching documents for information by reusing and integrating mature software components such as Lucene APIs, WORDNET, LSA techniques, and domain-specific controlled vocabulary. To evaluate the practical benefits, the prototype was used to query MEDLINE database, and to locate domain-specific controlled vocabulary terms in Materials and Process Specifications. Its extensibility has been demonstrated by incorporating a spell-checker for the input query, and by structuring the retrieved output into hierarchical collections for quicker assimilation. It is also being used to experimentally explore the relationship between LSA and document clustering using 20-mini-newsgroups and …
Power Transmission Control Using Distributed Max-Flow, Bruce M. Mcmillin, Austin Armbruster, Mariesa Crow, Michael R. Gosnell
Power Transmission Control Using Distributed Max-Flow, Bruce M. Mcmillin, Austin Armbruster, Mariesa Crow, Michael R. Gosnell
Computer Science Faculty Research & Creative Works
Existing maximum flow algorithms use one processor for all calculations or one processor per vertex in a graph to calculate the maximum possible flow through a graph's vertices. This is not suitable for practical implementation. We extend the max-flow work of Goldberg and Tarjan to a distributed algorithm to calculate maximum flow where the number of processors is less than the number of vertices in a graph. Our algorithm is applied to maximizing electrical flow within a power network where the power grid is modeled as a graph. Error detection measures are included to detect problems in a simulated power …

Evaluation Of Glycine Max Mrna Clusters, Ronald L. Frank, Fikret Erçal
Biological Sciences Faculty Research & Creative Works
Background: Clustering the ESTs from a large dataset representing a single species is a convenient starting point for a number of investigations into gene discovery, genome evolution, expression patterns, and alternatively spliced transcripts. Several methods have been developed to accomplish this, the most widely available being UniGene, a public domain collection of gene-oriented clusters for over 45 different species created and maintained by NCBI. The goal is for each cluster to represent a unique gene, but currently it is not known how closely the overall results represent that reality. UniGene's build procedure begins with initial mRNA clusters before joining ESTs. …

Civil and Environmental Engineering Faculty Publications and Presentations
A water quality model of Lake Whatcom, Washington was developed as part of a Total Maximum Daily Load Study for the Washington Department of Ecology. Lake Whatcom is a large natural lake which is listed on the 1998 Washington State 303(d) list of waterbodies which do not meet the criterion for dissolved oxygen. Located next to the city of Bellingham, it is approximately 10 miles long and has a surface area of approximately 5000 acres and a maximum depth of over 100 meters. Eutrophication processes in the lake have been accelerated in recent years perhaps by the availability of nutrients …
