Dynamic Analysis Of Less-Than-Truckload Shipments And Test Method To Simulate This Environment, Sher Paul Singh, E. Joneson, Jay Singh, G. Grewal
Industrial Technology and Packaging
This paper provides results from a comprehensive data measurement study that analyzed the vibration dynamics produced inside the trailers used for less-than truckload (LTL) shipments. The trailers used for this segment of the package transportation environment are very different in size and suspension than those used for full truckload shipments. This study measured the vertical, lateral and longitudinal vibration inside a trailer as a function of road surface. In addition, the study developed a video showing freight movement inside the trailer to determine physical displacement and shifting of the loads. A set of recommendations was developed to safely load and …
Protecting Critical Infrastructure With Games Technology, Adrian Boeing, Martin Masek, Bill Bailey
Protecting Critical Infrastructure With Games Technology, Adrian Boeing, Martin Masek, Bill Bailey
Australian Information Warfare and Security Conference
It is widely recognised that there is a considerable gap in the protection of the national infrastructure. Trying to identify what is in fact ‘critical’ is proving to be very difficult as threats constantly evolve. An interactive prototyping tool is useful in playing out scenarios and simulating the effect of change, however existing simulators in the critical infrastructure area are typically limited in the visual representation and interactivity. To remedy this we propose the use of games technology. Through its use, critical infrastructure scenarios can be rapidly constructed, tested, and refined. In this paper, we highlight the features of games …
Hybrid Bond-Order Potential For Silicon, Suleiman Oloriegbe
Hybrid Bond-Order Potential For Silicon, Suleiman Oloriegbe
All Dissertations
ABSTRACT
A new hybrid bond-order potential for silicon is developed. The functional form of the potential is derived from hybrid of expressions from empirical bond-order formalism and first principles approximations. The total energy is expressed as the sum of attractive, repulsive and promotion energies. By introducing a screening function derived from approximations to first principles expressions, the potential is made long-ranged by allowing covalent interactions beyond the first nearest neighbor shell of atoms in agreement with quantum mechanical descriptions of the bonding in silicon. Environment-dependent promotion energy is introduced that accurately accounts for energetic interactions due to changes in hybridization …
Modeling Upper Body Kinematics While Using A Transradial Prosthesis, Derek J. Lura
Modeling Upper Body Kinematics While Using A Transradial Prosthesis, Derek J. Lura
USF Tampa Graduate Theses and Dissertations
The prostheses used by the majority of persons with upper limb amputations today offer a limited range of motion. Relative to anatomical joints transradial (below the elbow) prosthesis users lose at least two of the three degrees of freedom provided by the wrist and forearm. Some myoeletric prostheses currently allow for forearm pronation and supination (rotation about an axis parallel to the forearm) and the operation of a powered prosthetic hand. Body-powered prostheses, incorporating hooks and other cable driven terminal devices, have even fewer active degrees of freedom. In order to perform activities of daily living, an amputee must use …
Mil_Civ Immersive Surface, Elizabeth M. Quick
Mil_Civ Immersive Surface, Elizabeth M. Quick
Architecture Thesis Prep
"The pervasive proliferation of complex tracking systems such as GPS and simulation gaming environments such as Full Spectrum Warrior are transforming the built environment into an immersive 1:1 map where all flows and transactions are measured, monitored, and tracked. The gap between map and real experience disappears resulting in an immersive map. The spatial implications of this real time 1:1 immersive map creates an opportunity for architecture itself to monitor, track, and measure flows and transactions. This tracking and simulation agenda plays out specifically in the design of a surface that integrates military training, military artifacts, and civilian recreation into …
An Engineering Evaluation Of Ankle Prosthetics, Christopher Thian, Stephen Tiernan, Fiona Mcevoy, Robert Flavin
An Engineering Evaluation Of Ankle Prosthetics, Christopher Thian, Stephen Tiernan, Fiona Mcevoy, Robert Flavin
Conference Papers
There are a wide range of different types of ankle replacements on the market today each with a
different mechanical design. Unfortunately the results of ankle replacements are not as good as hip
and knee replacements; this is due to the complexity of the ankle joint. In the early days of ankle
replacements some of the prosthetics only lasted 4 months. Recent developments have improved the
longevity of the replacements although, there are still many complications and failures of the
replacements, these include; the prosthetic components migrating into the bone, the components
failing due to stresses induced by the forces …

Modeling Systems For Optimal Resource Allocation, Scheduling, And Decision Making, Esengul Tayfur
All Dissertations
This dissertation focuses on the resource requirements and scheduling problem for logistic systems. We investigate solutions to this problem in two different logistic systems: logistic system of the health care facilities during emergency evacuations and delivery and distribution system of production industries. All hospitals must have an evacuation plan to ensure the safety of patients and prevent the loss of life. However, hospital operators have not been able to quantify how resource availability, the cost of acquiring those resources, and evacuation completion time are related. This research addresses this problem and contributes two methodologies to solve this problem. In the …

Radio Frequency Evaluation Of Oriented Strand Board, Xiaojian Liu
Theses and Dissertations
Oriented strandboard (OSB) is a wood-based composite product with the largest market share for residential and commercial construction. OSB composite products have introduced variability in their physical and mechanical properties due to their raw material and process variation. Reliable in-line non-destructive evaluation (NDE) devices are needed to rapidly determine OSB panel product quality during and after the manufacturing process. Wood specific gravity (SG) and moisture content (MC) play an important role in the wood composite manufacturing process. A real-time after-press monitoring device for locating SG and MC variations can supply information needed to control and improve mat formation, hot press …
An Open Framework For Highly Concurrent Real-Time Hardware-In-The-Loop Simulation, Ryan C. Underwood, Bruce M. Mcmillin, Mariesa Crow
An Open Framework For Highly Concurrent Real-Time Hardware-In-The-Loop Simulation, Ryan C. Underwood, Bruce M. Mcmillin, Mariesa Crow
Computer Science Faculty Research & Creative Works
Hardware-in-the-loop (HIL) real-time simulation is becoming a significant tool in prototyping complex, highly available systems. The HIL approach permits testing of hardware prototypes of components that would be extremely costly or difficult to test in the deployed environment. In power system simulation, key issues are the ability to wrap the systems of equations (such as Partial Differential Equations) describing the deployed environment into real-time software models, provide low synchronization overhead between the hardware and software, and reduce reliance on proprietary platforms. This paper introduces an open source HIL simulation framework that can be ported to any standard Unix-like system on …

Determining The Accuracy Of Item Parameter Standard Error Of Estimates In Bilog-Mg 3, Michael Toland
College of Education and Human Sciences: Dissertations, Theses, and Student Research
This study was conducted to determine the accuracy of item parameter standard error of estimates (SEEs) produced by BILOG-MG 3 by examining their performance under a variety of conditions. The Factors manipulated in this study were type of underlying difficulty (b) distribution, type of underlying discrimination (a) distribution, type of underlying lower asymptote (c) distribution, test length (I), type of underlying latent trait (θ) distribution, sample size (J), and the number of quadrature points. Results showed that the accuracy of the estimated SEb under the 1PL, 2PL, and 3PL models depended on the magnitude of the b parameter being estimated. …
Analytical Characterization Of Oscillon Energy And Lifetime, Marcelo Gleiser, David Sicilia
Analytical Characterization Of Oscillon Energy And Lifetime, Marcelo Gleiser, David Sicilia
Dartmouth Scholarship
We develop an analytical procedure to compute all relevant physical properties of scalar field oscillons in models with quartic polynomial potentials: energy, radius, frequency, core amplitude, and lifetime. We compare our predictions to numerical simulations of models with symmetric and asymmetric double-well potentials in three spatial dimensions, obtaining excellent agreement. We also explain why oscillons have not been seen to decay in two spatial dimensions.

System Dynamics Modelling: A Tool For Participatory Simulation Of Complex Water Systems Within Aquastress, L. S. Vamvakeridou-Lyroudia, Dragan Savic
International Congress on Environmental Modelling and Software
System Dynamics Modelling (SDM) is a methodology for studying and managing complex feedback systems, typically used when formal analytical models do not exist, but system simulation can be developed by linking a number of feedback mechanisms. Forrester (1961) introduced system thinking and SDM in the early 60’s as a modelling and simulation methodology for long-term decision-making in dynamic industrial management problems. Since then, SDM has been applied to various business policy and strategy problems (Barlas 2002). Consequently it has proven to be very useful for the simulation and study of complex environmental (Ford 1999, Mulligan and Wainwright 2004) and water …

The SENSOR project aims at delivering ex-ante Sustainability Impact Assessment Tools (SIAT) to support decision making on policies related to multifunctional land use in European regions. Decision support tools are required that provide scientifically substantiated anticipations of the effects of future policy options on sustainability issues. SENSOR responds to these information needs at European land use policy level with the SIAT, which is interactively designed with end users (Helming et al. 2008). This paper illustrates the design process of the SIAT under the concurrent condition of a high usability for end users. To meet this goal, end user involvements by …
A Methodology For Building Credible Models For Policy Evaluation, Craig Aumann
A Methodology For Building Credible Models For Policy Evaluation, Craig Aumann
International Congress on Environmental Modelling and Software
The need for tools capable of evaluating the potential impacts of alternative policies has been expressed by many. This paper focuses on a methodology that describes how credibility can be constructed for models used to evaluate alternative policies. Relative to modeling conducted in scientific contexts, however, modeling for policy evaluation has notable differences that would lead some to say that achieving credibility in such results is not possible. We first introduce a model assessment framework that enables us to describe how models for policy evaluation can still be more or less credible despite the differences from scientific modeling contexts. The …
Information And Communication Technologies And The Income Distribution: A General Equilibrium Simulation, T. Fukiharu
Information And Communication Technologies And The Income Distribution: A General Equilibrium Simulation, T. Fukiharu
International Congress on Environmental Modelling and Software
The special feature of the innovation in the information and communicationtechnologies (ICTs) implies the improvement in the quality of consumption of goods andservices including leisure hours, as well as the modification in the production process. Thetraditional analysis has emphasized solely the modification in the production process. Thispaper incorporates this special feature in analysing the relation between the innovation andthe income distribution. It has been argued that the innovation of ICTs expands theunfairness of income distribution. In the traditional expression, this may be rephrased thatthe wealthy capitalist class becomes relatively better off, while the poor working classbecomes relatively worse off. Assuming …
A Qualitative Reasoning–Based Curriculum For Learning About Sustainable Development, Tim Nuttle, Anders Bouwer
A Qualitative Reasoning–Based Curriculum For Learning About Sustainable Development, Tim Nuttle, Anders Bouwer
International Congress on Environmental Modelling and Software
Qualitative Reasoning (QR) has many qualities making it a useful ontology for educationabout system dynamics (Bredeweg and Forbus 2003). We implemented an onlinecurriculum for learning about sustainable development using QR in Moodle, an onlinecourse management system (http://www.moodle.org). This curriculum is centred onqualitative reasoning models that explore sustainable development situations in a five casestudies (Bredeweg et al. 2007), in addition to other models that explore specificsustainability issues. Each model is implemented using the QR model-building andinspecting workbench, Garp3 (Bredeweg et al. 2006). The “lesson” activity in Moodle isused to create a series of questions that guide learners stepwise through different scenariosfor …
Using Agile Software Development Practices In A Research Oriented Distributed Simulation, Douglas James Mielke
Using Agile Software Development Practices In A Research Oriented Distributed Simulation, Douglas James Mielke
Computational Modeling & Simulation Engineering Theses & Dissertations
Although sometimes controversial, agile methodologies have proven to be a viable choice for some software development projects. Projects suited to agile methodologies are those that involve new technology, have requirements that change rapidly, and are controlled by small, talented teams. Much literature about agile software development leans towards business products and non-government entities. Only a handful of literature resources mention agile software development being used in government contracts and even fewer resources mention research projects. NASA's Airspace and Traffic Operations Simulation (ATOS) is a research oriented simulation that doesn't follow the traditional business project mold. In an effort to gain …

Multi-Barge Flotilla Impact Forces On Bridges, Peng Yuan, Issam E. Harik, Michael T. Davidson
Multi-Barge Flotilla Impact Forces On Bridges, Peng Yuan, Issam E. Harik, Michael T. Davidson
Kentucky Transportation Center Research Report
The current AASHTO equations for barge impact loads are based on scale models of barges, and may not accurately predict impact loads on bridge piers. The results of this study produce more realistic flotilla impact design loads, potentially leading to a reduction in construction costs of bridges over navigable waterways. The objectives of this study are: (1) To conduct theoretical finite element analysis on various types of flotillas impacting bridge piers. The flotillas and the respective barges will be of the type commonly traversing Kentucky’s waterways; and (2) To generate design equations for barge/flotilla impact loads. The study concludes the …
Equivalent Barge And Flotilla Impact Forces On Bridge Piers, Peng Yuan, Issam E. Harik
Equivalent Barge And Flotilla Impact Forces On Bridge Piers, Peng Yuan, Issam E. Harik
Kentucky Transportation Center Research Report
Bridge piers located in navigable inland waterways are designed to resist impact forces from barges and flotillas in addition to other design considerations (e.g., scour, dead and live loads, etc.). The primary design tool for estimating these forces is the AASHTO Guide Specification which provides a simple hand calculation method for determining an “equivalent impact force”. The simplicity comes at a cost of excluding the effect of the pier shape, impact duration, and interaction between barges in a flotilla. The objective of this report is to present a hand calculation method for determining barge or flotilla equivalent static impact forces …
Large Scale Structure As A Probe Of Gravitational Slip, Scott F. Daniel, Robert R. Caldwell, Asantha Cooray, Alessandro Melchiorri
Large Scale Structure As A Probe Of Gravitational Slip, Scott F. Daniel, Robert R. Caldwell, Asantha Cooray, Alessandro Melchiorri
Dartmouth Scholarship
A new time-dependent, scale-independent parameter, ϖ, is employed in a phenomenological model of the deviation from general relativity in which the Newtonian and longitudinal gravitational potentials slip apart on cosmological scales as dark energy, assumed to be arising from a new theory of gravitation, appears to dominate the Universe. A comparison is presented between ϖ and other parametrized post-Friedmannian models in the literature. The effect of ϖ on the cosmic microwave background anisotropy spectrum, the growth of large-scale structure, the galaxy weak-lensing correlation function, and cross correlations of cosmic microwave background anisotropy with galaxy clustering are illustrated. Cosmological models with …
It Was And It Isn't: A Rhetorical Exploration Of Simulacra In Emerging Church Vintage Worship, Kevin Paul Mahan
It Was And It Isn't: A Rhetorical Exploration Of Simulacra In Emerging Church Vintage Worship, Kevin Paul Mahan
Masters Theses
Ironically, a new vintage movement of worship was being taught in a certain strand of the emerging church movement. Dan Kimball, pastor at Vintage Faith Church in Santa Cruz, California, established his teachings to reach the postmodern generation absent from seeker-sensitive churches in a text called The Emerging Church: Vintage Christianity for New Generations. This text suggested many elements, or symbols, for worshipers to include in vintage faith worship gatherings that would connect with the post-Christian culture. Eight of these symbols were chosen – the band, technology, video screen broadcasts, life-stage groups, ancient structures, light, symbols of the faith, and …
Ant Colony Optimization For Multilevel Assembly Job Shop Scheduling, M. Omkumar, P. Shahabudeen
Ant Colony Optimization For Multilevel Assembly Job Shop Scheduling, M. Omkumar, P. Shahabudeen
International Journal of Applied Management and Technology
Job shop scheduling is one of the most explored areas in the last few decades. Although it is very commonly witnessed in real-life situations, very less investigation has been carried out in scheduling operations of multi-level jobs, which undergo serial, parallel, and assembly operations in an assembly job shop. In this work, some of the dispatch rules, which have best performances in scheduling multilevel jobs in dynamic assembly job shop, are tested in static assembly job shop environment. A new optimization heuristic based on Ant Colony Algorithm is proposed and its performance is compared with the dispatch rules.
Leaf Area Index Simulation In Soybean Grown Under Near-Optimal Conditions, T. D. Setiyono, Albert Weiss, James E. Specht, Kenneth G. Cassman, A. Dobermann
Leaf Area Index Simulation In Soybean Grown Under Near-Optimal Conditions, T. D. Setiyono, Albert Weiss, James E. Specht, Kenneth G. Cassman, A. Dobermann
Department of Agronomy and Horticulture: Faculty Publications
Different approaches have been used to simulate leaf area index (LAI) in soybean (Glycine max L. Merr). Many of these approaches require genotype-specific calibration procedures. Studies modeling LAI dynamics under optimal growth conditions with yields close to the yield potential of soybean have remained scarce. A sink-driven approach was developed and evaluated for LAI simulation in soybean under near-optimal environments. The rate of change in expanding leaf area was simulated using the first derivative of a logistic function accounting for plant population density, air temperature, and water deficit. The rate of change in senescing leaf area was also simulated …
Monitoring The Process Mean Of Autocorrelated Data, Jesse Dorian King
Monitoring The Process Mean Of Autocorrelated Data, Jesse Dorian King
Electronic Theses and Dissertations
When modeling the stochastic behavior of a sequence { } t X of the quality measurement X on the output of a production process, it is usually assumed the measurements taken over time are independent and identically distributed. Multiple authors have pointed out that significant autocorrelation can affect the performance of traditional control charting procedures. One family of models for time series data are the autoregressive integrated moving average (ARIMA) models. These models are well suited to model production processes, in which the observations are autocorrelated. It is our interest to examine these models. Meaning is given to the process …
A Monte Carlo Approach For Exploring The Generalizability Of Performance Standards, James Thomas Coraggio
A Monte Carlo Approach For Exploring The Generalizability Of Performance Standards, James Thomas Coraggio
USF Tampa Graduate Theses and Dissertations
While each phase of the test development process is crucial to the validity of the examination, one phase tends to stand out among the others: the standard setting process. The standard setting process is a time-consuming and expensive endeavor. While it has received the most attention in the literature among any of the technical issues related to criterion-referenced measurement, little research attention has been given to generalizing the resulting performance standards. This procedure has the potential to improve the standard setting process by limiting the number of items rated and the number of individual rater decisions. The ability to generalize …
Performance Study Of Mpls And Ds Techniques To Improve Qos Routing For Critical Applications On Ip Networks, Salim Alsharif, Mohammad Mehdi Shahsavari
Performance Study Of Mpls And Ds Techniques To Improve Qos Routing For Critical Applications On Ip Networks, Salim Alsharif, Mohammad Mehdi Shahsavari
Electrical Engineering and Computer Science Faculty Publications
This paper aims to analyze the QoS performance of two main technology mechanisms, Multi-Protocol Label Switching (MPLS) and Differentiated Services (DS). The introduction of both mechanisms to support throughput and delay sensitive real-time media traffic will have an impact on critical applications with respect to QoS and traffic engineering. MPLS is a traffic forwarding mechanism that allows traffic to use multiple paths and DS is a mechanism that provides for aggregate traffic to be classified and conditioned at the edge of the network routers. The two modeled techniques and their performance will be evaluated with respect to their end-to-end delay. …

Modeling The Effects Of Value-Added Processing And Logistics Using Arena, Kurt A. Rosentrater, Elif Kongar
Kurt A. Rosentrater
Scarcity and cost of nonrenewable fossil fuels have been a growing focus of many energy-dependent nations, including the U.S., for the past couple of decades. There are mainly two ways to approach these problems: (1) reducing the energy dependency and/or (2) developing alternative means of energy production. Utilizing biofuels, which are renewable sources of energy, is a promising way to produce energy. But, as this industry grows, so too does the quantity of byproducts, which are known as DDGS. This paper discusses a model that has been developed to analyze the economic viability of DDGS processing, and includes both deterministic …
Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang
Modeling Crash Severity And Speed Profile At Roadway Work Zones, Zhenyu Wang
USF Tampa Graduate Theses and Dissertations
Work zone tends to cause hazardous conditions for drivers and construction workers since work zones generate conflicts between construction activities and the traffic, therefore aggravate the existing traffic conditions and result in severe traffic safety and operational problems. To address the influence of various factors on the crash severity is beneficial to understand the characteristics of work zone crashes. The understanding can be used to select proper countermeasures for reducing the crash severity at work zones and improving work zone safety. In this dissertation, crash severity models were developed to explore the factor impacts on crash severity for two work …
