Application Of The Analytic Hierarchy Process For Selecting And Modeling Stormwater Best Management Practices, Kevin D. Young, Tamim Younos, Randel L. Dymond, David F. Kibler, David H. Lee
Application Of The Analytic Hierarchy Process For Selecting And Modeling Stormwater Best Management Practices, Kevin D. Young, Tamim Younos, Randel L. Dymond, David F. Kibler, David H. Lee
Journal of Contemporary Water Research and Education
Engineers are increasingly expected to consider several influential criteria when selecting a single best management practice (BMP) for stormwater management. These criteria include site physical characteristics; local, state, and federal pollution control ordinances; stakeholder input, and BMP implementation and long-term maintenance costs. This paper discusses the development of a software-aided approach based on the Analytic Hierarchy Process (AHP) as a decision-making tool for selecting stormwater management BMPs. Supported with input from a geographic information system, the AHP can provide an objective, mathematically-based alternative to the existing, often subjective BMP selection approaches. In this study, the developed AHP decision support software …

Watershed Retrofit And Management Evaluation For Urban Stormwater Management Systems In North Carolina, Kathy M. Debusk, William F. Hunt, Upton Hatch, Olha Sydorovych
Journal of Contemporary Water Research and Education
In response to water quality concerns in the Jordan Lake Reservoir and state and federal mandates, several cities in North Carolina are being required for the first time to reduce nutrient loads in stormwater from previously developed lands; that is, install retrofits. It is anticipated that similar requirements will become necessary for other urban areas in North Carolina. The goal of this study is to evaluate the feasibility of alternative approaches to stormwater management for existing developments within North Carolina cities. Geographic coverage of the study included a portion of the New Hope Creek watershed, located within the City of …

Maintenance For Stormwater Treatment Practices, Andrew J. Erickson, John S. Gulliver, Joo-Hyon Kang, Peter T. Weiss, C. Bruce Wilson
Journal of Contemporary Water Research and Education
Maintenance is imperative to preserve performance and extend useable life of stormwater treatment practices. Increased attention to mass balance, numerical goals, total maximum daily loads (TMDLs), and antidegradation requirements has created the need for more emphasis on stormwater treatment practice maintenance in order to meet permitting and reporting requirements. The purpose of this paper is to advance short and long-term maintenance considerations so as to develop more realistic maintenance plans. To do so, a municipal public works survey was developed, distributed, and the results were analyzed. The results of the survey revealed that most (61 percent) cities and counties perform …

Survey Says: Implications Of A Public Perception Survey On Stormwater Education Programming, Katie Giacalone, Catherine Mobley, Calvin Sawyer, James Witte, Gene Eidson
Journal of Contemporary Water Research and Education
Effective watershed and stormwater education and public involvement programs strive to increase awareness of watersheds and landscape connectivity and also encourage behavior changes that may be contributing to water quality and quantity problems within a targeted basin. According to new guidance from the US Environmental Protection Agency on stormwater permit improvement, regulators are looking for programs to utilize targeted issues relevant to a community to guide the development of a comprehensive outreach program. In an effort to collect information on public perception, knowledge, behaviors and willingness to get involved in improved stormwater management, a telephone survey was implemented. This manuscript …
Formalizing A Conceptual Framework Of Work Domain Knowledge, Min Zhu
Formalizing A Conceptual Framework Of Work Domain Knowledge, Min Zhu
Dissertations and Theses (Open Access)
Background: The failure rate of health information systems is high, partially due to fragmented, incomplete, or incorrect identification and description of specific and critical domain requirements. In order to systematically transform the requirements of work into real information system, an explicit conceptual framework is essential to summarize the work requirements and guide system design. Recently, Butler, Zhang, and colleagues proposed a conceptual framework called Work Domain Ontology (WDO) to formally represent users’ work. This WDO approach has been successfully demonstrated in a real world design project on aircraft scheduling. However, as a top level conceptual framework, this WDO has not …

On The Capacity Of Immediately-Decodable Coding Schemes For Wireless Stored-Video Broadcast With Hard Deadline Constraints, Xiaohang Li, Chih-Chun Wang, Xiaojun Lin
Department of Electrical and Computer Engineering Technical Reports
Multimedia streaming applications have stringent Quality-of-Service (QoS) requirements. Typically each packet is associated with a packet delivery deadline. This work models and considers streaming broadcast of stored-video over the downlink of a single cell. We first generalize the existing class of immediately-decodable network coding (IDNC) schemes to take into account the deadline constraints. The performance analysis of IDNC schemes are significantly complicated by the packet deadline constraints (from the application layer) and the immediate-decodability requirement (from the network layer). Despite this difficulty, we prove that for independent channels, the IDNC schemes are asymptotically throughput-optimal subject to the deadline constraints when …
Does Entropic Gravity Bound The Masses Of The Photon And Graviton?, Jonas R. Mureika, R. B. Mann
Does Entropic Gravity Bound The Masses Of The Photon And Graviton?, Jonas R. Mureika, R. B. Mann
Physics Faculty Works
If the information transfer between test particle and holographic screen in entropic gravity respects both the uncertainty principle and causality, a lower limit on the number of bits in the universe relative to its mass may be derived. Furthermore, these limits indicate particles that putatively travel at the speed of light -- the photon and/or graviton -- have a non-zero mass m≥10−68 kg. This result is found to be in excellent agreement with current experimental mass bounds on the graviton and photon, suggesting that entropic gravity may be the result of a (recent) softly-broken local symmetry. Stronger bounds emerge …

A long-standing goal of science is to be able to understand how matter behaves at the atomic and subatomic level. How electrons rearrange when atoms or molecules come together is the essence of chemistry, and the ability to manipulate those rearrangements is the goal of the emerging sphere of nanotechnology. A fuller understanding could lead to enormous scientific and technological breakthroughs. Unfortunately, significant problems confront scientists and engineers in attacking the question. Not only are atoms and molecules very small, requiring highly specialized equipment to "see" them, everything at the atomic level happens very, very fast. For example, an electron …

Non-metallic particles and the metallic impurity elements in the solar cell silicon have a strong detrimental effect on the conversion efficiency of the solar cell. Removing these impurities is one of the important tasks for silicon refining. the current paper proposed a new approach to purify silicon - electromagnetic (EM) separation. Since the non-metallic particles and the metallic impurity elements are non- or less conductive while the molten silicon is well conductive, under EM field, the Lorenz force will push the particles to the boundary layer, thus separate these inclusions. in the current study, a high frequency EM field was …

A Comparative Analysis Of Changes In Postural Control Following Training Using The Wii Balance Program And Standardized Falls Prevention Programs, Alessandra Pluchino
A Comparative Analysis Of Changes In Postural Control Following Training Using The Wii Balance Program And Standardized Falls Prevention Programs, Alessandra Pluchino
Open Access Dissertations
Declines in balance and postural control are believed to be the major neuromuscular factors that contribute to an increased risk of falling with age. Balance training has been reported to be an effective tool for increasing these parameters in older fallers, but its effectiveness in improving balance in higher-functioning, independent-living elders is uncertain. PURPOSE: The purpose of this study was to compare the impact of two formal balance-training interventions (Tai Chi and standardize balance exercise program [SBEP]) and an activity-promoting video game, the Wii Fit balance program. METHODS: Twenty-nine healthy, independent seniors (72.10 ± 7.80) were randomly assigned to eight …
Extraction Of Contact Resistance In Carbon Nanofiber Via Interconnects With Varying Lengths, Ken Li, Patrick Wilhite, Vinit Khera, Shoba Krishnan, Xuhui Sun, Cary Y. Yang
Extraction Of Contact Resistance In Carbon Nanofiber Via Interconnects With Varying Lengths, Ken Li, Patrick Wilhite, Vinit Khera, Shoba Krishnan, Xuhui Sun, Cary Y. Yang
Electrical and Computer Engineering
A method to extract the contact resistance and bulk resistivity of vertically grown carbon nanofibers (CNFs) or similar one-dimensional nanostructures is described. Using a silicon-compatible process to fabricate a terrace test structure needed for the CNF length variation, the contact resistance is extracted by measuring in situ the resistances of individual CNFs with different lengths and within a small range of diameters using a nanoprober inside a scanning electron microscope. Accurate determination of contact resistances for various combinations of catalysts and underlayer metals can lead to eventual optimization of materials’ growth and device fabrication processes for CNF via interconnects.

Considerations For Wood River Sculpin Conservation: Historical Occurrence And Sampling Efficiency, Donald W. Zaroban
Considerations For Wood River Sculpin Conservation: Historical Occurrence And Sampling Efficiency, Donald W. Zaroban
Western North American Naturalist
Records of Wood River sculpin (Cottus leiopomus) from 1893 to 2003 were examined and new data were gathered in 2004 and 2006 to estimate the species’ historical range and to search for evidence of changes in its occurrence. Detections of Wood River sculpin were reported in 49 subwatersheds, primarily in the Idaho Batholith ecoregion. The remainder of the Wood River basin was classified as either potential historic range or unknown. Mark-recapture sampling was conducted to estimate the efficiency of electrofishing as a method to detect this sculpin. Sampling efficiency was calculated for 1 upstream pass and 1, 2, …

The Stream–Lake Ecotone: Potential Habitat For Juvenile Endangered June Suckers (Chasmistes Liorus), Russell B. Rader, Mark C. Belk, Rollin Hotchkiss, Jaron Brown
Western North American Naturalist
Potamodromous fish are poorly studied even though they are threatened often by human activities. The June sucker (Chasmistes liorus) is an endangered potamodromous species endemic to Utah Lake. Larval June suckers have not been collected from Utah Lake for at least 3 decades. Recruitment appears to be limited by low temperatures and scarce food, resulting in mass starvation of larval June suckers in the stream environment. We compared water temperature, zooplankton food availability, and small fish abundance in the stream and in 3 habitats along the stream–lake ecotone (dense emergent vegetation, sparse emergent vegetation, and open lake) to …

Indirect Adaptive Control Of An Active Filter Using Echo State Networks, Jing Dai, Ganesh K. Venayagamoorthy, Ronald G. Harley, Keith A. Corzine
Electrical and Computer Engineering Faculty Research & Creative Works
An active filter is a power electronic device used in a power system to decrease "harmonic current pollution" caused by nonlinear loads. the Echo State Network (ESN) has been widely used as an effective system identifier with much faster training speed than the other Recurrent Neural Networks (RNNs). However, only a few attempts have been made to use an ESN as a system controller. as the first attempt to use an ESN in indirect NeuroControl, this paper proposes an indirect adaptive NeuroControl scheme using two ESNs to control an active filter in a multiple-reference frame. as the first step in …
