Multi-Criteria Decision Analysis With Probabilistic Risk Assessment For The Management Of Contaminated Ground Water, I. Khadam, Jagath J. Kaluarachchi
Multi-Criteria Decision Analysis With Probabilistic Risk Assessment For The Management Of Contaminated Ground Water, I. Khadam, Jagath J. Kaluarachchi
Civil and Environmental Engineering Faculty Publications
Traditionally, environmental decision analysis in subsurface contamination scenarios is performed using cost–benefit analysis. In this paper, we discuss some of the limitations associated with cost–benefit analysis, especially its definition of risk, its definition of cost of risk, and its poor ability to communicate risk-related information. This paper presents an integrated approach for management of contaminated ground water resources using health risk assessment and economic analysis through a multi-criteria decision analysis framework. The methodology introduces several important concepts and definitions in decision analysis related to subsurface contamination. These are the trade-off between population risk and individual risk, the trade-off between the …
Remote Monitoring Of Repository Integrity Using Passive Seismic Arrays, Barbara Luke, Evangelos Yfantis
Remote Monitoring Of Repository Integrity Using Passive Seismic Arrays, Barbara Luke, Evangelos Yfantis
Publications (YM)
Once radioactive waste is emplaced in the repository, the challenge of monitoring the continued integrity of the excavated openings (e.g., emplacement drifts) escalates tremendously. We envision a seismic monitoring array installed on the surface at Yucca Mountain, which operates automatically to monitor repository opening stability in the long term. The objective is to monitor and validate the structural integrity of the emplacement drifts through identifying and localizing rock falls that could compromise drift access, hinder waste retrievability, and potentially reduce the effective life of waste canisters. Collateral benefits of the system include the ability to address some outstanding uncertainties regarding …
Experimental Study Of The Rheological Behaviors Of Fresh Concrete, Mortar, And Clay Grout, Cho-Liang Tsai, Yun Du, Yi-Shiun Tsai
Experimental Study Of The Rheological Behaviors Of Fresh Concrete, Mortar, And Clay Grout, Cho-Liang Tsai, Yun Du, Yi-Shiun Tsai
Journal of Marine Science and Technology–Taiwan
Most studies assume that fresh concrete is a Bingham fluid, but few studies precisely measure its Bingham constants, shear yield stress and viscosity, especially for normal fresh concrete. In stead of using commercial viscometer, this work developed a new experimental method and analytical procedure, based on the Stokes’ flow, for characterizing rheological properties of fluids. The experimental method developed here involved dragging a sphere submerged in the specimen fluid at a constant speed and measuring the resistance. Rheological properties of the specimen fluid can be calculated from the theoretical function correlating the drag velocity, drag force, and rheological properties of …
Finite Element Modelling Of Moisture Movement In Concrete Floors, Niall Holmes, Roger West
Finite Element Modelling Of Moisture Movement In Concrete Floors, Niall Holmes, Roger West
Conference papers
Predictive methods for determining the point at which it is safe to apply floor coverings to concrete floors can save time and money for the client, contractor and the floor installer. The current standard states that impervious floor coverings should not be applied until the surface of the floor reaches a relative humidity (RH) of 75%, established using a surface hygrometer test. Tests at Trinity College Dublin on drying concrete slabs in natural and forced drying environments show that there is a large variation in the residue of moisture deep in the concrete when the floor covering is applied, particularly …
Modeling And Control Of Vinyl Chloride In Drinking Water Distribution Systems, M Beardsley, Craig D. Adams
Modeling And Control Of Vinyl Chloride In Drinking Water Distribution Systems, M Beardsley, Craig D. Adams
Civil and Environmental Engineering Faculty Publications
In water distribution systems containing PVC pipe manufactured in the “early era” (prior to 1977), vinyl chloride can leach into drinking water resulting in vinyl chloride concentrations exceeding the 2 μg⋅L−1 maximum contaminant level. Field testing of dead-end segments of water distribution systems consisting of early-era PVC pipe was conducted to examine their initial intrapipe vinyl chloride monomer (VCM) concentrations based on a Fickian-diffusion-based leaching model. The experiments showed a wide range of VCM concentrations within early-era PVC pipe ranging from less than 50 to more than 600 mg⋅kg−1. Based on the diffusion modeling approach, a protocol was designed that …

Modeling Carrier Behavior In Sequential Auction Transportation Markets, Miguel Andres Figliozzi, Hani S. Mahmassani, Patrick Jaillet
Civil and Environmental Engineering Faculty Publications and Presentations
Online markets for transportation services, in the form of Internet sites that dynamically match shipments (shippers? demand) and transportation capacity (carriers? offer) through auction mechanisms are changing the traditional structure of transportation markets. A general framework for the study of carriers? behavior in a sequential auction transportation marketplace is provided. The unique characteristics of these marketplaces and the sources of difficulty in analyzing the behavior of these marketplaces are discussed. Learning and behavior in a sequential Vickrey auction marketplace is analyzed and simulated. Some results and the overall behavioral framework are also discussed.

A.M.I.S. And The Partitioning Of Preference, Ted H. Grossardt
Kentucky Transportation Center Presentations
This presentation reviews work by the researchers that combines group dialogic techniques with analytic hierarchy and GIS to bring the knowledge of large groups of people to bear on a highway routing problem. A significant question is how technical knowledge and local information can be combined, either dialogically or mathematically, to provide the most faithful and practical version of a collaborative preference surface, what we call the Analytic Minimum Impedance Surface, or AMIS. While all preferences can be summed directly for this purpose, it may be more accurate and effective to partition the preference contribution to the landscape by knowledge …

Model State Land Use Legislation For New England, New England Environmental Finance Center, Muskie School Of Public Service
Model State Land Use Legislation For New England, New England Environmental Finance Center, Muskie School Of Public Service
Legislation
Sprawl is neither the ordained nor the inevitable outcome upon the New England landscape. A coordinated response to sprawl by the public and private sectors is possible, and could dramatically improve land use patterns and reduce the cost of local government. For the New England states, such a response would include, among other elements, legislation to eliminate existing gaps in the land use laws of each state – gaps that presently encourage or sanction sprawling development. It would also include incentives for municipalities to think beyond their borders and to act with greater efficiency and effect. It is the purpose …
Applicability Of Risk-Based Management And The Need For Risk-Based Economic Decision Analysis At Hazardous Waste Contaminated Sites, I. Khadam, Jagath J. Kaluarachchi
Applicability Of Risk-Based Management And The Need For Risk-Based Economic Decision Analysis At Hazardous Waste Contaminated Sites, I. Khadam, Jagath J. Kaluarachchi
Civil and Environmental Engineering Faculty Publications
Decision analysis in subsurface contamination management is generally carried out through a traditional engineering economic viewpoint. However, new advances in human health risk assessment, namely, the probabilistic risk assessment, and the growing awareness of the importance of soft data in the decision-making process, require decision analysis methodologies that are capable of accommodating non-technical and politically biased qualitative information. In this work, we discuss the major limitations of the currently practiced decision analysis framework, which evolves around the definition of risk and cost of risk, and its poor ability to communicate risk-related information. A demonstration using a numerical example was conducted …

Comparison Matrix Method And Its Applications To Damage Evaluation For Existing Reinforced Concrete Bridges, Ming-Te Liang, Chin-Ming Lin, Chi-Jang Yeh
Journal of Marine Science and Technology–Taiwan
The main purpose of this paper was adopting the comparison matrix method, which is generated from both the analytic hierarchy process and the principle of moment equilibrium, to assess the repair order of existing reinforced concrete (RC) bridges. Ten existing RC bridges in Keelung, Taiwan, were given as an illustrative example. In order to verify the feasibility and reliability of the proposed method, the D (Degree) E (Extend) R (Relevancy) evaluation method, which is now widely used to evaluate the damage grade for existing RC bridges in Taiwan, was also applied to assessing the same ten existing RC bridges. The …

Extensive subsurface exploration of Yuen-Lin liquefaction area was conducted by National Science Council after Chi-Chi earthquakes. Data obtained from the subsurface exploration in Yuen-Lin area had been studied and three widely used liquefaction evaluation methods, i.e. Seed method, T-Y method and JRA method, were employed for liquefaction evaluation. The depth of the liquefied soil layer was also identified by comparison of grain size distribution curve of explored sample and field data. Iwasaki's liquefaction potential index was further used to analyze liquefaction induced risk of damage. Finally, Multiple Additive Decision Making method (MADM) was applied to determine the suitability of the …
Development Of A Multivariate Logistic Model To Predict Bicycle Route Safety In Urban Areas, Cheryl Allen-Munley
Development Of A Multivariate Logistic Model To Predict Bicycle Route Safety In Urban Areas, Cheryl Allen-Munley
Dissertations
In response to the renewed appreciation of the benefits of bicycling to the environment and public health, public officials across the nation are working to establish new bicycle routes. During the past two decades, a number of methods have been endorsed for the selection of "suitable" bicycle routes. These methods are limited in that they do not explicitly address bicycle safety nor do they reflect urban conditions.
The purpose of this research is to develop an objective bicycle route safety rating model based on injury severity. The model development was conducted using a logistic transformation of Jersey City's bicycle crash …
