Passive Fathometer Processing, Peter Gerstoft, William S. Hodgkiss, Martin Siderius, Chen-Fen Huang, Chris H. Harrison Dec 2007

Passive Fathometer Processing, Peter Gerstoft, William S. Hodgkiss, Martin Siderius, Chen-Fen Huang, Chris H. Harrison

Electrical and Computer Engineering Faculty Publications and Presentations

Ocean acoustic noise can be processed efficiently to extract Green's function information between two receivers. By using noise array-processing techniques, it has been demonstrated that a passive array can be used as a fathometer [Siderius, et al., J. Acoust. Soc. Am. 120, 1315-1323 (2006)]. Here, this approach is derived in both frequency and time domains and the output corresponds to the reflection sequence. From this reflection sequence, it is possible to extract seabed layering. In the ocean waveguide, most of the energy is horizontally propagating, whereas the bottom information is contained in the vertically propagating noise. Extracting the seabed ...


What Is Rcu, Fundamentally?, Paul E. Mckenney, Jonathan Walpole Dec 2007

What Is Rcu, Fundamentally?, Paul E. Mckenney, Jonathan Walpole

Computer Science Faculty Publications and Presentations

Read-copy update (RCU) is a synchronization mechanism that was added to the Linux kernel in October of 2002. RCU achieves scalability improvements by allowing reads to occur concurrently with updates. In contrast with conventional locking primitives that ensure mutual exclusion among concurrent threads regardless of whether they be readers or updaters, or with reader-writer locks that allow concurrent reads but not in the presence of updates, RCU supports concurrency between a single updater and multiple readers. RCU ensures that reads are coherent by maintaining multiple versions of objects and ensuring that they are not freed up until all pre-existing read-side ...


The Impacts Of Congestion On Commercial Vehicle Tours Characteristics And Costs, Miguel A. Figliozzi Dec 2007

The Impacts Of Congestion On Commercial Vehicle Tours Characteristics And Costs, Miguel A. Figliozzi

Civil and Environmental Engineering Faculty Publications and Presentations

Congestion is a common phenomenon in all major cities of the world. Increased travel time and uncertainty brought about by congestion impacts the efficiency of logistics operations. Recent studies indicate that a significant proportion of commercial vehicle kilometers traveled (VKT) and vehicle hours traveled (VHT) are generated by trip-chains or multi-stop tours. This paper presents research demonstrating the impact of congestion on multi-stop tours in urban areas. An analytical model, numerical experiments, and real-world tour data are used to understand the impact of congestion on tour characteristics, carriers? costs, VKT, and VHT. This research shows that travel time/distance between ...


Analysis Of Freight Tours In A Congested Urban Area Using Disaggregated Data: Characteristics And Data Collection Challenges, Miguel Andres Figliozzi, Lynsey Kingdon, Andrea Wilkitzki Dec 2007

Analysis Of Freight Tours In A Congested Urban Area Using Disaggregated Data: Characteristics And Data Collection Challenges, Miguel Andres Figliozzi, Lynsey Kingdon, Andrea Wilkitzki

Civil and Environmental Engineering Faculty Publications and Presentations

Confidentiality issues are usually an insurmountable barrier that precludes the collection of detailed and complete freight data. However, when detailed disaggregated truck activity data is available, the analysis of commercial vehicle routes and trip chain structures can provide insightful information about urban commercial vehicle tours, travel patterns, and congestion levels. Where truck data is usually aggregated and cross-sectional, this research analyzes several months of detailed truck activity records in a congested urban area and thus contributes a level of investigation unavailable with aggregated data. To the best of the author's knowledge, there is no published research regarding the analysis ...


The Urban Heat Island Mitigation Impact Screening Tool (Mist), David J. Sailor, Nikolaas Dietsch Oct 2007

The Urban Heat Island Mitigation Impact Screening Tool (Mist), David J. Sailor, Nikolaas Dietsch

Mechanical and Materials Engineering Faculty Publications and Presentations

A web-based software tool has been developed to assist urban planners and air quality management officials in assessing the potential of urban heat island mitigation strategies to affect the urban climate, air quality, and energy consumption within their cities. The user of the tool can select from over 170 US cities for which to conduct the analysis, and can specify city-wide changes in surface reflectivity and/or vegetative cover. The Mitigation Impact Screening Tool (MIST) then extrapolates results from a suite of simulations for 20 cities to estimate air temperature changes associated with the specified changes in surface characteristics for ...


A Comparison Of Five Models For Estimating Clear-Sky Solar Radiation, Robert Leslie Annear, Scott A. Wells Oct 2007

A Comparison Of Five Models For Estimating Clear-Sky Solar Radiation, Robert Leslie Annear, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

Many agencies in the USA are developing management approaches to address water quality concerns and threatened and endangered species habitat requirements in water bodies. Many of these water bodies are water quality limited for temperature. Factors influencing stream temperature include: streamside vegetation, topographic shading, inflows and outflows, stream width, stream depth, light extinction and solar radiation. One of the key driving factors in estimating a water body heat budget is calculating the amount of solar radiation incident on the water surface. Even though it is preferable to measure clear-sky solar radiation, many temperature models rely on theoretical estimates of clear-sky ...


Terahertz Scattering From Granular Material, Lisa M. Zurk, Brian Orlowski, Dale P. Winebrenner, Eric I. Thorsos, Megan R. Leahy-Hoppa, L. Michael Hayden Aug 2007

Terahertz Scattering From Granular Material, Lisa M. Zurk, Brian Orlowski, Dale P. Winebrenner, Eric I. Thorsos, Megan R. Leahy-Hoppa, L. Michael Hayden

Electrical and Computer Engineering Faculty Publications and Presentations

Terahertz (THz) imaging is emerging as a potentially powerful method of detecting explosive devices, even in the presence of occluding materials. However, the characteristic spectral signatures of pure explosive materials may be altered or obscured by electromagnetic scattering caused by their granular nature. This paper presents THz transmission measurements of granular systems representative of explosives and presents results from dense media theory that accurately explain the observed scattering response.


Particle Shape As Revealed By Spectral Depolarization, Donald D. Duncan, Michael Eugene Thomas Aug 2007

Particle Shape As Revealed By Spectral Depolarization, Donald D. Duncan, Michael Eugene Thomas

Electrical and Computer Engineering Faculty Publications and Presentations

Through a series of numerical simulations we explore some scatter effects due to nonspherical particles. Specifically, we examine the link between the aspect ratio of randomly oriented, prolate spheroidal particles and the resulting linear depolarization of the scattered light in the forward and backscatter directions. The particular objective is to detect the presence of randomly oriented particles that have a systematic size and aspect ratio. Calculations show that the spectral behavior of the linear depolarization reveals the aspect ratio of the scattering particles. The concept is demonstrated using the size, shape, and refractive index of the spore form of Bacillus ...


Pricing In Dynamic Vehicle Routing Problems, Miguel Andres Figliozzi, Hani S. Mahmassani, Patrick Jaillet Aug 2007

Pricing In Dynamic Vehicle Routing Problems, Miguel Andres Figliozzi, Hani S. Mahmassani, Patrick Jaillet

Civil and Environmental Engineering Faculty Publications and Presentations

The principal focus of this paper is to study carrier pricing decisions for a type of vehicle routing problems defined in a competitive and dynamic environment. This paper introduces the vehicle routing problem in a competitive environment (VRPCE) as an extension of the traveling-salesman problem with profits (TSPP) to a dynamic competitive auction environment. In the VRPCE, the carrier must estimate the incremental cost of servicing new service requests as they arrive dynamically. The paper presents a rigorous and precise treatment of the sequential pricing and costing problem that a carrier faces in such an environment. The sequential pricing problem ...


Understanding The Safety Effects Of Roadway Illumination Reductions, Christopher M. Monsere, Thareth Yin, Michael Wolfe Aug 2007

Understanding The Safety Effects Of Roadway Illumination Reductions, Christopher M. Monsere, Thareth Yin, Michael Wolfe

Civil and Environmental Engineering Faculty Publications and Presentations

In 2001, Oregon’s governor responded to a perceived future energy shortage in the Pacific Northwest by directing all state agencies to reduce power consumption by 10 percent. After review of power saving opportunities, the Oregon Department of Transportation (ODOT) elected to include selective illumination reductions on Oregon interstate highways as part of their energy saving strategy. The illumination reductions occurred at interchanges and along lineal highway sections between October 2001 and April 2002. A total of 47 interchanges and 6.03 miles of interstate highways were modified. Changes in illumination were broadly classified as either full (including high-mast) to ...


A Decision Support Model For Project Manager Assignments, Peerasit Patanakul, Dragan Milošević, Timothy R. Anderson Aug 2007

A Decision Support Model For Project Manager Assignments, Peerasit Patanakul, Dragan Milošević, Timothy R. Anderson

Engineering and Technology Management Faculty Publications and Presentations

The question, "How to assign projects to project managers?" is considered to be one of the most important questions in project management. Nevertheless, methods to answer this question have not yet been sufficiently addressed in the literature. In practice, even though the question is rather common, practitioners still seek an effective project assignment methodology - especially, for the assignments of project managers of multiple concurrent projects, such as a project manager of new product development projects in typical high-technology industries. To respond to this question, we performed an inductive study to develop a theoretical framework for project assignments, including some significant ...

Civil and Environmental Engineering Faculty Publications and Presentations

The Washington Department of Ecology is interested in developing a temperature Total Maximum Daily Load (TMDL) allocation for the Pend Oreille River between the Albeni Falls Dam (U.S. Army Corps of Engineer’s reservoir) and Box Canyon Dam as shown in Figure 1. The Pend Oreille drainage basin is shown in Figure 2. An existing model of the Box Canyon reach was updated from CE-QUALW2 Version 3.0 to Version 3.5. This current research involves improving the calibration of the original model (1997 and 1998) and expanding the model using 2004 as an additional data set for calibration ...


Analyses Of Internal Solitary Waves Generated At The Columbia River Plume Front Using Sar Imagery, Jiayi Pan, David A. Jay Jul 2007

Analyses Of Internal Solitary Waves Generated At The Columbia River Plume Front Using Sar Imagery, Jiayi Pan, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

Internal solitons generated at the Columbia River plume front during ebb tide are displayed on a synthetic aperture radar (SAR) image taken on 26 July 2004 at 14:24:22 UTC. Scale analyses suggest that these internal solitons belong to the finite-depth category. A theoretical model, relating the radar backscatter cross section to dynamic parameters of internal solitons in the continuous stratification, is developed. Using the model and background stratification data collected by the River Influences on Shelf Ecosystem (RISE) project in July 2004, we extract the soliton dynamic parameters of the half-width, amplitude, phase speed, and average energy flux ...


Improving Arterial Performance Measurement Using Traffic Signal System Data, Michael Wolfe, Christopher Monsere, Peter Koonce, Robert L. Bertini Jul 2007

Improving Arterial Performance Measurement Using Traffic Signal System Data, Michael Wolfe, Christopher Monsere, Peter Koonce, Robert L. Bertini

Civil and Environmental Engineering Faculty Publications and Presentations

The characterization of the performance of freeways in real time and on a historical basis has been successfully achieved for many years. The ability to characterize arterial performance has been more elusive. Currently numerous applications of traffic management and traveler information systems include freeways but lack the ability to extend their operation to major arterials. This paper describes methods for quantifying arterial performance using data from signal system loop detectors. Included in the array of metrics are traffic density, total delay, predicted travel time, and signal coordination effectiveness. Methods for determining performance in these areas are adapted for use in ...


Nature-Inspired Interconnects For Self-Assembled Large-Scale Network-On-Chip Designs, Christof Teuscher Jun 2007

Nature-Inspired Interconnects For Self-Assembled Large-Scale Network-On-Chip Designs, Christof Teuscher

Electrical and Computer Engineering Faculty Publications and Presentations

Future nanoscale electronics built up from an Avogadro number of components need efficient, highly scalable, and robust means of communication in order to be competitive with traditional silicon approaches. In recent years, the networks-on-chip (NoC) paradigm emerged as a promising solution to interconnect challenges in silicon-based electronics. Current NoC architectures are either highly regular or fully customized, both of which represent implausible assumptions for emerging bottom-up self-assembled molecular electronics that are generally assumed to have a high degree of irregularity and imperfection. Here, we pragmatically and experimentally investigate important design tradeoffs and properties of an irregular, abstract, yet physically plausible ...


Modeling Effects Of Channel Complexity And Hyporheic Flow On Stream Temperatures, Chris Berger, Scott A. Wells Jun 2007

Modeling Effects Of Channel Complexity And Hyporheic Flow On Stream Temperatures, Chris Berger, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

Stream temperatures are affected by multiple forcing functions, including surface heat exchange (including solar radiation, evaporation, conduction, and net long wave radiation) and hyporheic flows. Each of these forcing functions is directly influenced by the level of channel complexity in the stream channel and riparian shading. The interrelationship between channel complexity, hyporheic flow and stream temperature is highly complex, and efforts to manage for habitat diversity by managing channel complexity could result in unintended consequences on stream temperature. When planning modifications to stream channel complexity, consideration should be given to the effects such moderations could have on stream temperatures.

Non-Laser-Based Scanner For Three-Dimensional Digitization Of Historical Artifacts, Donald D. Duncan, Daniel V. Hahn, Kevin C. Baldwin

Electrical and Computer Engineering Faculty Publications and Presentations

A 3D scanner, based on incoherent illumination techniques, and associated data-processing algorithms are presented that can be used to scan objects at lateral resolutions ranging from 5 to 100 m (or more) and depth resolutions of approximately 2 m. The scanner was designed with the specific intent to scan cuneiform tablets but can be utilized for other applications. Photometric stereo techniques are used to obtain both a surface normal map and a parameterized model of the object’s bidirectional reflectance distribution function. The normal map is combined with height information, gathered by structured light techniques, to form a consistent 3D ...


An Emotional Mimicking Humanoid Biped Robot And Its Quantum Control Based On The Constraint Satisfaction Model, Quay Williams, Scott Bogner, Michael Kelley, Carolina Castillo, Martin Lukac, Dong Hwa Kim, Jeff S. Allen, Mathias I. Sunardi, Sazzad Hossain, Marek Perkowski May 2007

An Emotional Mimicking Humanoid Biped Robot And Its Quantum Control Based On The Constraint Satisfaction Model, Quay Williams, Scott Bogner, Michael Kelley, Carolina Castillo, Martin Lukac, Dong Hwa Kim, Jeff S. Allen, Mathias I. Sunardi, Sazzad Hossain, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

The paper presents a humanoid robot that responds to human gestures seen by a camera. The behavior of the robot can be completely deterministic as specified by a Finite State Machine that maps the sensor signals to the effector signals. This model is further extended to the constraints-satisfaction based model that links robots vision, motion, emotional behavior and planning. One way of implementing this model is to use adiabatic quantum computer which quadratically speeds-up every constraint problem and will be thus necessary to solve large problems of this type. We propose to use the remotely-connected Orion system by DWAVE Corporation.


Effects Of Ocean Thermocline Variability On Noncoherent Underwater Acoustic Communications, Martin Siderius, Michael B. Porter, Paul Hursky, Vincent Mcdonald Apr 2007

Effects Of Ocean Thermocline Variability On Noncoherent Underwater Acoustic Communications, Martin Siderius, Michael B. Porter, Paul Hursky, Vincent Mcdonald

Electrical and Computer Engineering Faculty Publications and Presentations

The performance of acoustic modems in the ocean is strongly affected by the oceanenvironment. A storm can drive up the ambient noise levels, eliminate a thermocline by wind mixing, and whip up violent waves and thereby break up the acoustic mirror formed by theocean surface. The combined effects of these and other processes on modem performance are not well understood. The authors have been conducting experiments to study these environmental effects on various modulation schemes. Here the focus is on the role of the thermocline on a widely used modulation scheme (frequency-shift keying). Using data from a recent experiment conducted ...


Spontaneous Mode Locking In Mixed-Broadened Laser Oscillators, Pitak Chenkosol, Lee W. Casperson Apr 2007

Spontaneous Mode Locking In Mixed-Broadened Laser Oscillators, Pitak Chenkosol, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A theoretical model is reported for spontaneous mode locking in mixed-broadened laser oscillators. Experimental observations of this effect have been available for many years, but no rigorous interpretation has been given. Numerical calculations emphasize the case of a high-gain xenon laser, for which extensive experimental data have been published. Complex pulsation characteristics are observed as the cavity length and pumping rate are varied, and the theoretical results are in good agreement with the experimental data.

A Hybrid Simulation Model For Studying Acute Inflammatory Response, Wayne W. Wakeland, Louis Macovsky, Gary An Jan 2007

A Hybrid Simulation Model For Studying Acute Inflammatory Response, Wayne W. Wakeland, Louis Macovsky, Gary An

Systems Science Faculty Publications and Presentations

The modeling of complex biological systems presents a significant challenge. Central to this challenge is striking a balance between the degree of abstraction required to facilitate analysis and understanding, and the degree of comprehensiveness required for fidelity of the model to its reference-system. It is likely necessary to utilize multiple modeling methods in order to achieve this balance. Our research created a hybrid simulation model by melding an agent-based model of acute local infection with a system dynamics model that reflects key systemic properties. The agent based model was originally developed to simulate global inflammation in response to injury or ...


Inductive Learning Of Quantum Behaviors, Marek Perkowski, Martin Lukac Jan 2007

Inductive Learning Of Quantum Behaviors, Marek Perkowski, Martin Lukac

Electrical and Computer Engineering Faculty Publications and Presentations

In this paper studied are new concepts of robotic behaviors - deterministic and quantum probabilistic. In contrast to classical circuits, the quantum circuit can realize both of these behaviors. When applied to a robot, a quantum circuit controller realizes what we call quantum robot behaviors. We use automated methods to synthesize quantum behaviors (circuits) from the examples (examples are cares of the quantum truth table). The don’t knows (minterms not given as examples) are then converted not only to deterministic cares as in the classical learning, but also to output values generated with various probabilities. The Occam Razor principle, fundamental ...


Realization Of Incompletely Specified Functions In Minimized Reversible Cascades, Marek Perkowski, Manjith Kumar, Bala Iyer, Natalie Metzger, Ying Wang Jan 2007

Realization Of Incompletely Specified Functions In Minimized Reversible Cascades, Marek Perkowski, Manjith Kumar, Bala Iyer, Natalie Metzger, Ying Wang

Electrical and Computer Engineering Faculty Publications and Presentations

There is a need to convert non-reversible functions to their corresponding reversible functions to be realized as reversible cascades. The original MMD (D.M.Miller, D. Maslov, and G.W.Dueck) algorithm for synthesis of reversible functions using cascades of reversible gates [1] can be modified to allow for the inclusion of “don't cares” within the given function's truth table (reversible or irreversible). This was achieved in the approach presented, by first initializing the “don't cares” to binary values, synthesizing the network using the base MMD algorithm, comparing the cost, and iterating to find an implementation with ...

Using Building Energy Simulation And Geospatial Modeling Techniques In Determine High Resolution Building Sector Energy Consumption Profiles, Shem C. Heiple

Dissertations and Theses

A technique is presented for estimating hourly and seasonal energy consumption profiles in the building sector at spatial scales down to the individual taxlot or parcel. The method combines annual building energy simulations for cityspecific prototypical buildings and commonly available geospatial data in a Geographical Information System (GIS) framework. Hourly results can be extracted for any day and exported as a raster output at spatial scales as fine as an individual parcel (
