Modeling Irda Performance: The Effect Of Irlap Negotiation Parameters On Throughput, Scott V. Hansen, Charles D. Knutson, Michael G. Robertson, Franklin E. Sorenson Oct 2001

Modeling Irda Performance: The Effect Of Irlap Negotiation Parameters On Throughput, Scott V. Hansen, Charles D. Knutson, Michael G. Robertson, Franklin E. Sorenson

Faculty Publications

The Infrared Data Association's (IrDA) infrared data transmission protocol is a widely used mechanism for short-range wireless data communications. In order to provide flexibility for connections between devices of potentially disparate capabilities, IrDA devices negotiate the values of several transmission parameters based on the capabilities of the devices establishing the connection. This paper describes the design and implementation of a software tool, Irdaperf, to model IrDA performance based on negotiated transmission parameters. Using Irdaperf, we demonstrate that for fast data rates, maximizing window size and data size are key factors for overcoming the negative effects of a relatively long link …

Poynting's Theorem And Luminal Total Energy Transport In Passive Dielectric Media, Scott Glasgow, Michael Ware, Justin Peatross Sep 2001

Poynting's Theorem And Luminal Total Energy Transport In Passive Dielectric Media, Scott Glasgow, Michael Ware, Justin Peatross

Faculty Publications

Without approximation the energy density in Poynting's theorem for the generally dispersive and passive dielectric medium is demonstrated to be a system total dynamical energy density. Thus the density in Poynting's theorem is a conserved form that by virtue of its positive definiteness prescribes important qualitative and quantitative features of the medium-field dynamics by rendering the system dynamically closed. This fully three-dimensional result, applicable to anisotropic and inhomogeneous media, is model independent, relying solely on the complex-analytic consequences of causality and passivity. As direct applications of this result, we show 1 that a causal medium responds to a virtual, instantaneous …

Rethinking The Approach To The Microenterprise Sector In Latin America: An Intergrating Framework, Jaime Ortiz Sep 2001

Rethinking The Approach To The Microenterprise Sector In Latin America: An Intergrating Framework, Jaime Ortiz

Journal of Microfinance / ESR Review

Unavoidable macroeconomic adjustment policies have exacerbated social inequalities in Latin America. As a result, electoral platforms have identified microenterprises as an alternative economic activity to help alleviate poverty. Pursuing an efficient microentrepreneurial base requires from governments a comprehensive package of both financing and training strategies. Conversely, microentrepreneurs require a better understanding of their activity in order to set forward arguments that will allow them to enhance their management practices. Government policies towards the microenterprise sector should create favorable conditions conducive to the establishment and operation of financial institutions as well as specialized nongovernmental organizations providing training and consulting. Within that …

Financial Performance Of Selected Microfinance Institutions: Benchmarking Progress To Sustainability, Michael Tucker Sep 2001

Financial Performance Of Selected Microfinance Institutions: Benchmarking Progress To Sustainability, Michael Tucker

Journal of Microfinance / ESR Review

A few microfinance institutions (MFIs) have implemented best business practices and made the transition to fully regulated financial institutions. Many more are in the process of undertaking this transformation or at least considering it. Rising competition among growing numbers of MFIs for both funding and clients has made improved financial performance a necessity for most if not all MFIs. Financial ratios of 17 Latin American MFIs are compared to benchmark performance ratios for the industry and with commercial Latin American banks. This small sample of data, while useful, also underlines the need for more widespread MFI reporting. Complicating reliance on …

Improving Cluster Utilization Through Set Based Allocation Policies, Quinn O. Snell, Julio C. Facelli, Brian D. Haymore, David B. Jackson Sep 2001

Improving Cluster Utilization Through Set Based Allocation Policies, Quinn O. Snell, Julio C. Facelli, Brian D. Haymore, David B. Jackson

Faculty Publications

While clusters have already proven themselves in the world of high performance computing, some clusters are beginning to exhibit resource inefficiencies due to increasing hardware diversity. Much of the success of clusters lies in the use of commodity components built to meet various hardware standards. These standards have allowed a great level of hardware backwards compatibility that is now resulting in a condition referred to as hardware 'drift' or heterogeneity. The hardware heterogeneity introduces problems when diverse compute nodes are allocated to a parallel job, as most parallel jobs are not self-balancing. This paper presents a new method that allows …

Livelock Avoidance For Meta-Schedulers, Mark J. Clement, John Jardine, Quinn O. Snell Aug 2001

Livelock Avoidance For Meta-Schedulers, Mark J. Clement, John Jardine, Quinn O. Snell

Faculty Publications

Meta-scheduling, a process which allows a user to schedule a job across multiple sites, has a potential for livelock. Current systems avoid livelock by locking down resources at multiple sites and allowing a metascheduler to control the resources during the lock down period or by limiting job size to that which will fit on one site. The former approach leads to poor utilization; the later poses limitations on job size. This research uses BYU's Meta-scheduler (YMS) which allows jobs to be scheduled across multiple sites without the need for locking down the nodes. YMS avoids livelock through exponential back-off This …

Two Hymns Based On Nephi's Psalm, John S. Tanner Jul 2001

Two Hymns Based On Nephi's Psalm, John S. Tanner

Journal of Book of Mormon Studies

The first line of Nephi’s Psalm (found in 2 Nephi 4:16– 35) matches perfectly the iambic pentameter of Jean Sibelius’s Finlandia, more commonly known among Latter-day Saints as the hymn Be Still, My Soul. Because of this coincidence, John S. Tanner decided to write lyrics based on Nephi’s Psalm, called I Love the Lord, after which he solicited the help of Ronald J. Staheli in composing a musical arrangement based on Finlandia. Tanner later wrote another adaptation of Nephi’s Psalm, called Sometimes My Soul, using the tune of an American folk song. He explains the process of writing these two …

The Book Of Mormon And Dialogic Revelation, Terryl L. Givens Jul 2001

The Book Of Mormon And Dialogic Revelation, Terryl L. Givens

Journal of Book of Mormon Studies

This article has been adapted from the author’s book By the Hand of Mormon: The American Scripture That Launched a New World Religion. The author discusses three common understandings of the term revelation: (1) revelation as doctrine, (2) revelation as history, and (3) revelation as inner experience. He suggests that the Book of Mormon introduces a fourth type: revelation as dialogue. This form of revelation allows individuals to have direct contact with God, rather than only through the scriptures, and can be applied to our lives just as it was to the lives of those living in Book …

Effects Of Exotic Species On Yellowstone's Grizzly Bears, Daniel P. Reinhart, Mark A. Haroldson, David J. Mattson, Kerry A. Gunther Jul 2001

Effects Of Exotic Species On Yellowstone's Grizzly Bears, Daniel P. Reinhart, Mark A. Haroldson, David J. Mattson, Kerry A. Gunther

Western North American Naturalist

Humans have affected grizzly bears (Ursus arctos horribilis) by direct mortality, competition for space and resources, and introduction of exotic species. Exotic organisms that have affected grizzly bears in the Greater Yellowstone Area include common dandelion (Taraxacum officinale), nonnative clovers (Trifolium spp.), domesticated livestock, bovine brucellosis (Brucella abortus), lake trout (Salvelinus namaycush), and white pine blister rust (Cronartium ribicola). Some bears consume substantial amounts of dandelion and clover. However, these exotic foods provide little digested energy compared to higher-quality bear foods. Domestic livestock are of greater energetic value, but …

Biological Invasions—How Are They Affecting Us, And What Can We Do About Them?, Daniel Simberloff Jul 2001

Biological Invasions—How Are They Affecting Us, And What Can We Do About Them?, Daniel Simberloff

Western North American Naturalist

Nonindigenous species affect native ecosystems, communities, and populations in myriad ways, from plants (and a few animals) that overgrow entire communities, to plants and animals that hybridize individual native species to a sort of genetic extinction. Further, nonindigenous species sometimes interact to worsen each others impact. These impacts are commonly seen in national parks throughout the United States. The key policy change required to alleviate this threat is a shift from blacklists of prohibited species and a presumption of harmlessness to combinations of white and blacklists and a presumption that any species may be damaging. This new guiding philosophy must …

Annotated Checklist Of Exotic Vascular Plants In Yellowstone National Park, Jennifer J. Whipple Jul 2001

Annotated Checklist Of Exotic Vascular Plants In Yellowstone National Park, Jennifer J. Whipple

Western North American Naturalist

Documentation of the arrival of exotic vascular plants in Yellowstone National Park has been sporadic. An annotated checklist of exotic vascular plants is presented, with information about the approximate arrival time in the park of each species and the current extent of the infestation. Yellowstones flora includes 187 exotic vascular plant species (14.8% of the flora), and the park has an extrapolated mean number of exotic species per 10 km2 of 47.3. The situation in Yellowstone is compared with other areas in North America. The increase in exotics mirrors a corresponding increase in visitation.

Mountain Goats In The Greater Yellowstone Ecosytem: A Prehistoric And Historical Context, Paul Schullery, Lee Whittlesey Jul 2001

Mountain Goats In The Greater Yellowstone Ecosytem: A Prehistoric And Historical Context, Paul Schullery, Lee Whittlesey

Western North American Naturalist

Because the relatively recent colonization of portions of Yellowstone National Park by introduced mountain goats (Oreamnos americanus) from public game lands in Montana raises important policy and management questions for the park, it is necessary to understand the prehistoric and early historical record of mountain goats in the Greater Yellowstone Ecosystem. We reviewed previous paleontological, archeological, and historical studies of goat presence and examined a large body of historical material for evidence of goats. Native mountain goat range most closely approached the Greater Yellowstone Ecosystem to the west, but no modern authority claims goats were resident in the …

Status And Conservation Of Salmonids In Relation To Hydrologic Integrity In The Greater Yellowstone Ecosystem, Robert W. Van Kirk, Lyn Benjamin Jul 2001

Status And Conservation Of Salmonids In Relation To Hydrologic Integrity In The Greater Yellowstone Ecosystem, Robert W. Van Kirk, Lyn Benjamin

Western North American Naturalist

Native salmonid status was evaluated with an index quantifying distribution and abundance of cutthroat trout (Oncorhynchus clarki) and grayling (Thymallus arcticus) in 41 watersheds comprising the Greater Yellowstone Ecosystem. We assessed hydrologic integrity with a percentile-based index measuring cumulative effects of reservoirs, surface water withdrawals, and consumptive water use. Status of native salmonids was poor in 70% of the watersheds; exceptions occurred in a north-south core extending from the Upper Yellowstone southward through the national parks to Bear Lake. Hydrologic integrity was highest in headwater areas and lowest in lower-elevation watersheds. Status of native and nonnative …

Lazy Training: Improving Backpropagation Learning Through Network Interaction, Timothy L. Andersen, Tony R. Martinez, Michael E. Rimer Jul 2001

Lazy Training: Improving Backpropagation Learning Through Network Interaction, Timothy L. Andersen, Tony R. Martinez, Michael E. Rimer

Faculty Publications

Backpropagation, similar to most high-order learning algorithms, is prone to overfitting. We address this issue by introducing interactive training (IT), a logical extension to backpropagation training that employs interaction among multiple networks. This method is based on the theory that centralized control is more effective for learning in deep problem spaces in a multi-agent paradigm. IT methods allow networks to work together to form more complex systems while not restraining their individual ability to specialize. Lazy training, an implementation of IT that minimizes misclassification error, is presented. Lazy training discourages overfitting and is conducive to higher accuracy in multiclass problems …

Contributions From Mafic Alkaline Magmas To The Bingham Porphyry Cu-Au-Mo Deposit, Utah, U.S.A., Daniel T. Maughan Jul 2001

Contributions From Mafic Alkaline Magmas To The Bingham Porphyry Cu-Au-Mo Deposit, Utah, U.S.A., Daniel T. Maughan

Theses and Dissertations

The Bingham porphyry Cu-Au-Mo deposit, Utah, may only be world-class because of substantial contributions of sulfur and metals from mafic alkaline magma to an otherwise unremarkable calc-alkaline system. Volcanic mafic alkaline rocks in the district are enriched in Cr, Ni, and Ba as well as ore-related constituents of Cu, Au, platinum group elements (PGE) and S. The bulk of the volcanic section that is comagmatic with ore-related porphyries is dacitic to trachytic in composition, but has inherited the geochemical signature of high Cr, Ni, and Ba from magma mixing with the mafic alkaline rocks. The volcanic section that most closely …

The Evacuation Of The Czechoslovak And German Missions At The Outbreak Of World War Ii, David F. Boone Jul 2001

The Evacuation Of The Czechoslovak And German Missions At The Outbreak Of World War Ii, David F. Boone

BYU Studies

The evacuation of Latter-day Saint missionaries from Europe at the outbreak of World War II was truly a unique event in Church history. At the beginning of World War I, a few American missionaries serving in Europe were moved to areas of safety, but until 1939 there had never been a large-scale evacuation of missionaries as a result of their being endangered by impending war (fig. 1). As the threat of war gathered over Europe in the late 1930s, Latter-day Saint Church leaders in Salt Lake City watched anxiously. In August 1939, there were missionaries laboring in Great Britain, Germany, …

Tools Leave Marks: Material Analysis Of The Scotford-Soper-Savage Michigan Relics, Richard B. Stamps Jul 2001

Tools Leave Marks: Material Analysis Of The Scotford-Soper-Savage Michigan Relics, Richard B. Stamps

BYU Studies

Extensive collections of supposedly prehistoric artifacts known as the Michigan Relics or the Scotford-Soper-Savage collection—possibly as many as 3,000 pieces—exist across the country. I have personally examined more than 1,000 from four different collections. What is so special about this collection of artifacts? Why does it merit further study? Although numerous previous studies have suggested that the materials were not made by ancient people but are of modern origin, there is ongoing interest in the collections. Dr. John Halsey, the state archaeologist of Michigan, says that his office gets more requests to see these materials than any other single collection. …

On The Utility Of Entanglement In Quantum Neural Computing, Dan A. Ventura Jul 2001

On The Utility Of Entanglement In Quantum Neural Computing, Dan A. Ventura

Faculty Publications

Efforts in combining quantum and neural computation are briefly discussed and the concept of entanglement as it applies to this subject is addressed. Entanglement is perhaps the least understood aspect of quantum systems used for computation, yet it is apparently most responsible for their computational power. This paper argues for the importance of understanding and utilizing entanglement in quantum neural computation.

An Evaluation Of Shared Multicast Trees With Multiple Active Cores, Daniel Zappala, Aaron Fabbri Jul 2001

An Evaluation Of Shared Multicast Trees With Multiple Active Cores, Daniel Zappala, Aaron Fabbri

Faculty Publications

Core-based multicast trees use less router state, but have significant drawbacks when compared to shortest-path trees, namely higher delay and poor fault tolerance. We evaluate the feasibility of using multiple independent cores within a shared multicast tree. We consider several basic designs and discuss how using multiple cores improves fault tolerance without sacrificing router state. We examine the performance of multiple-core trees with respect to single-core trees and find that adding cores significantly lowers delay without increasing cost. Moreover, it takes only a small number of cores, placed with a k-center approximation, for a multiple-core tree to have lower delay …

Economy And 'New Economy' In The United States And Germany, Phillip J. Bryson Jul 2001

Economy And 'New Economy' In The United States And Germany, Phillip J. Bryson

Faculty Publications

The expression "New Economy" is used inconsistently. This Article review the driving forces of the US boom of the 1990s, examining the changes introduced in the period and before, focusing on the IT sector and new technologies. The "New Economy" is not just the new sectors, but changes in the overall economy emanating from them. These changes will not evaporate in an economic slowdown. Comparisons of the USA with Germany and Europe illustrate that the "New Economy" will also continue to develop there on the foundations already laid.
