A Decision Model For Recommending Which Building Occupants Should Move Where During Fire Emergencies, 2016 CUNY John Jay College
A Decision Model For Recommending Which Building Occupants Should Move Where During Fire Emergencies, Norman E. Groner
Publications and Research
This paper describes a decision model for managing the movement of building occupants during ﬁre emergencies. Currently available guidance from standard practice, egress modeling, codes and the re-search literature, is too general to provide much help to persons charged with the responsibility of where groups of occupants should be located given a ﬁre scenario. The occupant movement decision model described in the paper uses three basic yes–no questions to divide building occupants into groups during a ﬁre emergency. For any particular group, the decision model recommends one of two basic actions:(1) people remain where they are already located ...

The purpose of this work was to determine the overall environmental impacts associated with the co-firing hazardous waste by burning in a cement kiln to replace the use of coal in the cement manufacturing process. This environmental assessment was conducted using LCA methodology. Understanding the environmental impacts associated with burning hazardous waste in a cement factory could help shape national environmental policy, regulations and the need for site specific human health risk assessments in the environmental regulatory permitting processes. Accordingly, the primary objective of this study was to evaluate the environmental impacts from the hazardous waste burning for energy recovery ...
Probability-Based Hurricane Resilience Evaluation And Retrofitting For Residential Community, 2016 Michigan Technological University
Probability-Based Hurricane Resilience Evaluation And Retrofitting For Residential Community, Yadong Dong
Dissertations, Master's Theses and Master's Reports
Wood residential construction is vulnerable to hurricanes, as evident in recent hurricane events. Many studies indicated that the changing climate may very likely alter hurricane patterns, which could lead to more severe hurricane damage to the wood residential construction that accounts for 90% of the residence in the USA. On the other hand, deterioration of material increases the chance of structural failure by reducing the structural capacity (e.g., corrosion of fasteners in roof panel could significantly reduce the withdrawal capacity of the roofing structure during hurricane events).
Currently, most hurricane damage estimations only focus on direct loss (e.g ...

Using Mavt To Incorporate Public Perception When Choosing A Nuclear Fuel Cycle, 2016 Virginia Commonwealth University
Using Mavt To Incorporate Public Perception When Choosing A Nuclear Fuel Cycle, Stephen Clement
Theses and Dissertations
Nuclear energy is a source of carbon free power. With many countries striving to make deep carbon cuts in their energy sectors, nuclear energy could be a large part of the solution. One of the main obstacles standing in the way of the use of nuclear energy is the issue of used nuclear fuel disposal. According to the NEI, the U.S. creates about 2000 metric tons of used nuclear fuel per year and has generated around 76,000 metric tons of used nuclear fuel over the last 4 decades. While there are technical problems that need to be solved ...
Strategies For Reducing Supplier Risk: Inputs Into The Supply Chain, 2016 University of Massachusetts Amherst
Strategies For Reducing Supplier Risk: Inputs Into The Supply Chain, Christopher A. Greene
There are many aspects to consider when managing an entire supply chain from procurement to fulfillment. Complex assemblies require hundreds of components, sourced from all corners of the globe, to come together in a synchronized fashion. Given the magnitude of the supply chain, high quality standards, and significantly increased outsourcing, there is a strong need to monitor supplier risk and quickly identify and mitigate potential problems. Moreover, the continuous pressure to reduce resources and pressure to cut costs, further increases the need for the development of procedures and tools that can quickly and efficiently address these potential supply chain risks ...

Safety Implications Of Transit Operator Schedule Policies, Hung Hoang
UNF Graduate Theses and Dissertations
In the bus transit community, driving long hours or spending extra hours at work are very common. This is true in the State of Florida, where bus transit is a very popular mode of public transportation. Although the correlation between a bus driver’s schedule and a crash event appears intuitive, further study regarding the effects of operator driving schedules on accident rates is needed to evaluate safety measures. The focus of this research is on the examination of bus driver schedules, and the effects of scheduling on accident rates in Florida. Data were collected at five bus transit agencies ...
Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, 2016 Embry-Riddle Aeronautical University
Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, Karim Hardy
Extreme situations as wildland fires are a source of stress and pressure. In such events, decision-makers and incident commanders need to address a specific problem: how to manage time and resources to make meaningful decisions? Current models of accidents that exist to explain and manage catastrophes and disasters are inadequate and insufficient to deal with resources and time pressure due to uncertainty within a complex organization. Current incident response structures are incompetent and impotent to handle effectively a dynamic evolution of space and time in order to bring a situation back to stability adequately.
Dividing And Conquering Meshes Within The Nist Fire Dynamics Simulator (Fds) On Multicore Computing Systems, 2015 University of Tennessee - Knoxville
Dividing And Conquering Meshes Within The Nist Fire Dynamics Simulator (Fds) On Multicore Computing Systems, Donald Charles Collins
The National Institute for Standards and Technology (NIST) Fire Dynamics Simulator (FDS) provides a computational fluid dynamics model of a fire, which can be visualized by using NIST Smokeview (SMV). Users must create a configuration file (*.fds) that describes the environment and other characteristics of the fire scene so that the FDS software can produce the output file (*.smv) needed for visualization.The processing can be computationally intensive, often taking between several minutes and several hours to complete. In many cases, a user will create a file that is not optimized for a multicore computing system. By dividing meshes within ...
Fault Diagnosis And Failure Prognostics Of Lithium-Ion Battery Based On Least Squares Support Vector Machine And Memory Particle Filter Framework, 2015 University of Tennessee - Knoxville
Fault Diagnosis And Failure Prognostics Of Lithium-Ion Battery Based On Least Squares Support Vector Machine And Memory Particle Filter Framework, Mohammed Ali Lskaafi
123456A novel data driven approach is developed for fault diagnosis and remaining useful life (RUL) prognostics for lithium-ion batteries using Least Square Support Vector Machine (LS-SVM) and Memory-Particle Filter (M-PF). Unlike traditional data-driven models for capacity fault diagnosis and failure prognosis, which require multidimensional physical characteristics, the proposed algorithm uses only two variables: Energy Efficiency (EE), and Work Temperature. The aim of this novel framework is to improve the accuracy of incipient and abrupt faults diagnosis and failure prognosis. First, the LSSVM is used to generate residual signal based on capacity fade trends of the Li-ion batteries. Second, adaptive threshold ...
Evaluating Launch Vehicle / Reentry Vehicle (Lv/Rv) Separation Concepts, 2015 The MITRE Corporation
Evaluating Launch Vehicle / Reentry Vehicle (Lv/Rv) Separation Concepts, Zheng Tao, Ganghuai Wang, Tudor Masek, Thomas J. St. Clair
Space Traffic Management Conference
Launch Vehicle/Reentry Vehicle (LV/RV) operations are expected to increase across the National Airspace System (NAS) as their reliability and availability improve. LV/RV designs and the industry landscape have vastly changed since the 1960’s, and the Federal Aviation Administration’s (FAA) methods for handling these operations need to evolve to support the expected growth. Currently, large amounts of airspace are segregated for every LV/RV operation. This increases costs for NAS users and may limit LV/RV opportunities. The FAA’s NextGen office recently proposed two more efficient separation concepts for LV/RV operations called Space Transition ...

A Multi-Criteria Gis-Based Route Selection Tool For Hazardous Material Transport: Consideration Of Environmental Consequence, Traffic Congestions And Costs, Bahareh Inanloo
FIU Electronic Theses and Dissertations
Hazardous materials are substances that, if not regulated, can pose a threat to human populations and their environmental health, safety or property when transported in commerce. About 1.5 million tons of hazardous material shipments are transported by truck in the US annually, with a steady increase of approximately 5% per year.
The objective of this study was to develop a routing tool for hazardous material transport in order to facilitate reduced environmental impacts and less transportation difficulties, yet would also find paths that were still compelling for the shipping carriers as a matter of trucking cost. The study started ...
A Method Of Mapping Sinkhole Susceptibility Using A Geographic Information System: A Case Study For Interstates In The Karst Counties Of Virginia, 2015 University of Virginia - Main Campus
A Method Of Mapping Sinkhole Susceptibility Using A Geographic Information System: A Case Study For Interstates In The Karst Counties Of Virginia, Alexandra L. Todd, Lindsay Ivey-Burden
Sinkhole Conference 2015
Karst terrain is landscape underlain by limestone that has been chemically dissolved by acidic groundwater, producing subsurface voids that pose risks for sinkholes if the overlaying soils can no longer support their own weight and collapse. The western counties of Virginia are heavy in karst due to their natural, geographic boundary of the western Ridge Province and the eastern Blue Ridge Mountain Range. As a result, the Commonwealth of Virginia Hazard Mitigation Plan recommends that the Virginia Department of Transportation (VDOT) develop a method to determine the roadways and regions most susceptible to experiencing sinkholes, in an effort to reduce ...

A Machine Learning Approach To Post-Market Surveillance Of Medical Devices, Jonathan Bates, Shu-Xia Li, Craig Parzynski, Ronald Coifman, Harlan Krumholz, Joseph Ross
Yale Day of Data
Post-market surveillance is a collection of processes and activities used by product manufacturers and regulators, such as the U.S. Food and Drug Administration (FDA) to monitor the safety and effectiveness of medical devices once they are available for use “on the market”. These activities are designed to generate information to identify poorly performing devices and other safety problems, accurately characterize real-world device performance and clinical outcomes, and facilitate the development of new devices, or new uses for existing devices. Typically, a device is monitored by comparing adverse events in the exposed population to a matched unexposed population. This research ...
Developing An Optimal Model For Infant Home Visitation, 2015 University of Tennessee - Knoxville
Developing An Optimal Model For Infant Home Visitation, Isaac Atuahene
The United States, Great Britain, Denmark, Canada and many other countries have accepted home visitation (HV) as a promising strategy for interventions for infants after births and for their mothers. Prior HV studies have focused on theoretical foundations, evaluations of programs, cost/benefit analysis and cost estimation by using hospital/payer/insurance data to prove its effectiveness and high cost. As governments and private organizations continue to fund HVs, it is an opportune time to develop and formulate operations research (OR) models of HV coverage, quality and cost so they might be used in program implementation as done for adult ...
Modelling Supercomputer Maintenance Interrupts: Maintenance Policy Recommendations, 2015 University of Tennessee - Knoxville
Modelling Supercomputer Maintenance Interrupts: Maintenance Policy Recommendations, Jagadish Cherukuri
A supercomputer is a repairable system with large number of compute nodes interconnected to work in harmony to achieve superior computational performance. Reliability of such a complex system depends on an effective maintenance strategy that involves both emergency and preventive maintenance. This thesis analyzes the maintenance records of four supercomputers operational at The National Institute of Computational Science located at Oak Ridge National Laboratory. We propose to use the generalized proportional intensities model (GPIM) to model the maintenance interrupts as it can capture both the reliability parameters and maintenance parameters and allows the inclusion of both emergency and preventive maintenance ...
Requirements For A Computer Code System For The Development And Maintenance Of Target Sets, 2015 University of Tennessee - Knoxville
Requirements For A Computer Code System For The Development And Maintenance Of Target Sets, Christopher Chwasz
In the field of commercial nuclear reactor security, the concept of target sets has matured since its invention in the late 1980s and early 1990s to the codification of target set regulations by the United States Nuclear Regulatory Commission in 2009 and publishing of official guidance in 2010. Target sets have evolved into a complex and useful tool to develop and test a protective strategy. By their definition, target sets are the “minimum combination of equipment or operator actions which, if all are prevented from performing their intended safety function or prevented from being accomplished, would likely result in significant ...
