The Viability Of Is Enhanced Knowledge Sharing In Mission-Critical Command And Control Centers, Sameh A. Sabet

Dissertations

Engineering processes such as the maintenance of mission-critical infrastructures are highly unpredictable processes that are vital for everyday life, as well as for national security goals. These processes are categorized as Emergent Knowledge Processes (EKP), organizational processes that are characterized by a changing set of actors, distributed knowledge bases, and emergent knowledge sharing activities where the process itself has no predetermined structure. The research described here utilizes the telecommunications network fault diagnosis process as a specific example of an EKP. The field site chosen for this research is a global undersea telecommunication network where nodes are staffed by trained personnel …

Constitutive Modeling Of The Thermo-Mechanics Associated With Crystallizable Shape Memory Polymers, Gautam Barot

Dissertations

This research addresses issues central to material modeling and process simulations. Here, issues related for developing constitutive model for crystallizable shape memory polymers are addressed in details. Shape memory polymers are novel material that can be easily formed into complex shapes, retaining memory of their original shape even after undergoing large deformations. The temporary shape is stable and return to the original shape is triggered by a suitable mechanism such heating the polymer above a transition temperature. Crystallizable shape memory polymers are called crystallizable because the temporary shape is fixed by a crystalline phase, while return to the original shape …

Feasibility Of Superconductivity In Semiconductor Superlatices, Kenneth P. Walsh

Dissertations

The objective of this thesis is to explore superconductivity in semiconductor superlattices of alternating hole and electron layers. The feasibility of superconductivity in semiconductor superlattices is based on a model formulated by Harshrnan and Mills. In this model, a semiconductor superlattice forms the layered electron and hole reservoirs of high transition temperature (high-Tc) superconductors.

A GaAs-A1xGa1-xAs semiconductor structure is proposed which is predicted to superconduct at Tc = 2.0 K and may be analogous to the layered electronic structure of high-Tc superconductors. Formation of an alternating sequence of electron- and hole-populated quantum wells (an electron-hole superlattice) in a modulation-doped GaAs- …

Analytical Model For Staging Emergency Evacuations, Vivek V. Korikanthimath

Dissertations

Disaster response in areas of high population density is centered on the efficient evacuation of people and possibly goods. Developing evacuation plans suitable for different levels of urgency based on the intensity of threat is a challenging task. In case of densely populated cities (e.g., New York, Los Angeles), the level of threat is enhanced by the congestion of their transportation systems, and the decision to evacuate a region simultaneously or by dividing it into multiple stages (or zones) affects the required evacuation time and associated delays.

The evolution of the traffic conditions on the evacuation route can vary significantly …

Selected Problems Of Inference On Branching Processes And Poisson Shock Model, Satrajit Roychoudhury

Dissertations

This dissertation explores the development of statistical methodology for some problems of branching processes and poisson shock model.

Branching process methods have become extremely popular in recent days. This dissertation mainly explores two fundamental inference problems of Galton-Watson processes. The first problem is concerned with statistical inference regarding the nature of the process. Two methodologies have been developed to develop a statistical test for the null hypothesis that the process is supercritical versus an alternative hypothesis that the process is non-supercritical. Another problem we investigate involves the estimation of the 'age' of a Galton-Watson Process. Three different methods are discussed …

Cameroon: Feasibility Study And Topographical Survey Of Water Supply, Justin Forzano

ETHOS Technical Reports

Justin Forzano traveled to Cameroon, West Africa to initiate collaboration with a non-government organization, the Organization for Sustainable Rural Infrastructure (OSRI). OSRI specializes in sensitizing communities on the importance of potable water as well as developing the physical and social infrastructure of developing rural communities in the South West province of Cameroon. In doing so, OSRI has constructed water supply schemes, bridges and community buildings and organized community development committees to promote social awareness. Forzano traveled to existing project sites to study the structure of rural water supply schemes and understand the importance of a completed water supply scheme and …

Brazil: Wood-Burning Stove Cost Cuts, John Succo

ETHOS Technical Reports

After getting introduced to the grounds of Ecofagoa, the job site where I would be working for the next couple of months, I was then quickly rushed into the project that I was assigned too. Josh Heyne was my U.D. engineering partner that came with me to Brazil. He had flown in two weeks previous to me and new Portuguese a lot better than I did so he was nice enough to give it his best shot in translating what Ronaldo, part owner of Ecofagoa, wanted me to do. Josh did in fact speak Portuguese a lot better then I …

Detection Of Proteins By Two-Photon Excitation Of Native Fluorescence, Li Li

Theses and Dissertations

Proteins are of primary importance to the structure and function of all living cells. Study of proteins relies on the ability to separate a complex mixture so that individual proteins can be more easily processed by other techniques. Since protein samples often exist at low concentration in a small volume, the trend in chemical analysis is toward micro total analysis systems (µTAS) or lab-on-a-chip devices. Among µTAS separation methods, the relatively new electric field gradient focusing (EFGF) technique has shown potential. It focuses and separates analytes based on their electrophoretic migration in an opposing hydrodynamic flow. The detection principles that …

A Wireless Method For Monitoring Medication Compliance, Jeffrey Scott Jonas

Theses

There are many devices on the market to help remind patients to take their pills, but most require observation by a caregiver to assure medication compliance. This project demonstrates three modes to detect pill removal from a pillbox: a switch under the pills, a reflective type photointerrupter and a transmissive "electric eye" photosensor. Each mode exhibited blind spots or other failures to detect pill presence, but by combining modes with complementary characteristics, the accuracy of pill detection is greatly increased.

Two methods of caregiver notification are demonstrated: text messages transmitted via an attached cellular phone, or the status is collected …

Fences And Deer-Damage Management: A Review Of Designs And Efficacy, Kurt C. Vercauteren, Michael J. Lavelle, Scott Hygnstrom

United States Department of Agriculture Wildlife Services: Staff Publications

White-tailed deer (Odocoileus virginianus) may cause more damage than any other species of wildlife. These damages include crop loss, automobile and aviation collisions, disease transmission, environmental degradation, and destruction of ornamental plantings. One practical method of controlling deer damage is the use of exclusionary fences. The relatively high cost of labor and materials required to build effective fences has limited most applications to the protection of orchards, vegetable farms, other high-value resources, and mitigation of human health and safety risks. Improvements in fence technology resulting in less expensive, yet effective fences have expanded the use of fences to manage damage …

Dem Simulated Floor Pressure Induced By A Granular Column, Shawn A. Chester

Theses

At the end of the 19th century, H. A. Janssen discovered that the bottom floor pressure in a cylindrical container of granular material asymptotes exponentially to a value less than the weight of the material i.e., the pressure becomes independent of the fill height of the column. This phenomenon is investigated using discrete element simulations of inelastic, frictional spheres in a cylindrical vessel having a particle-to-cylinder diameter ratio at approximately 13.3 or 26.6, with varying bed heights in both cases. The axial pressure profile and the load experienced by a piston that is supporting the granular column are computed. In …

Earthshine : Photometry, Modeling, And Spectral Observations, Jeffrey Patrick Hickey

Theses

The Earthshine group has been making sustained observations of the Earthshine from Big Bear Solar Observatory in California since late 1998. There have also been intermittent observations from 1994-5. High and low resolution Earthshine spectral observations have also been under taken at Palomar Observatory since 1999. The group has re-invigorated and modernized a nearly forgotten way of measuring the Earth's albedo, and hence its energy balance, previously studied by Danjon (and his followers) for about twenty-five years early in the last century, using their observations of the Earthshine from France. This is an overview paper covering observations, reductions, simulations, and …

Blackbird Use And Damage Of Wildlife Conservation Sunflower Plots: The Second Year, Jonathan M. Raetzman, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Annual blackbird damage to sunflower is valued at $5 to $10 million. Perhaps more importantly, the National Sunflower Association has identified blackbirds as the key reason for growers to abandon sunflower in areas of prime production. North Dakota and South Dakota together produce approximately 70% of sunflower grown in the United States. This crop adds $906 million to the regional economy. To date, cost effective and environmentally safe methods to reduce bird damage to sunflower remain elusive. In the 1980’s, scientists from the National Wildlife Research Center (NWRC) showed that “decoy” sunflower plots can greatly reduce bird damage to local …

Scientific Expertise In Policymaking: The Case For Open Review And Patent Reform, Beth Simone Noveck

ExpressO

The Energy Research Advisory Board, the group of external scientific advisors that provided impartial expert advice to the Secretary of Energy since 1978, was disbanded this May. The Administration, like its predecessors, regularly replaces experts on agency advisory panels with ideologues and political allies. We are at the nadir of a historical progression since World War II away from trust in and use of scientific expertise in policymaking. This shift however, has not been countered with greater public participation. Instead, administrative law and theory have developed a model of the managerial administrative authority. The "expertocratic" agency relies on internal expertise …

Jumping On The Mommy Track: A Tax For Working Mothers, Jessica C. Kornberg

ExpressO

“Jumping on the Mommy Track: a Tax for Working Mothers,” was written in response to recent data suggesting that mothers experience a wage penalty unrelated to diminished work productivity or commitment. This Article starts from the assumption that a wage penalty, in combination with already existing disadvantages to working mothers embedded in the tax code, drives women out of the workforce and into less economically efficient activity. The Article proposes remedying this distortion by implementing a targeted regressive tax on working mothers.
