In Search Of Something More: My Path Towards International Service-Learning In Engineering Education, Margaret Pinnell Jan 2010

In Search Of Something More: My Path Towards International Service-Learning In Engineering Education, Margaret Pinnell

Mechanical and Aerospace Engineering Faculty Publications

My personal and professional travels led me toward global education, in particular the University of Dayton (UD) program Engineers in Technical Humanitarian Opportunities for Service-Learning (ETHOS). I do not believe I ever intended to become part of an international engineering education program. In fact, I think the international piece was just a bonus. What really drew me to the ETHOS program was what initially draws our students to the program - a desire to "help" people. In order for the reader to understand how I ended up being involved in global education through the ETHOS program, I must first explain …


A Macrobending Singlemode Fiber Refractive Index Sensor For Low Refractive Index Liquids, Pengfei Wang, Yuliya Semenova, Yong Li, Qiang Wu, Gerald Farrell Jan 2010

A Macrobending Singlemode Fiber Refractive Index Sensor For Low Refractive Index Liquids, Pengfei Wang, Yuliya Semenova, Yong Li, Qiang Wu, Gerald Farrell

Articles

An all-fiber refractive index sensor with a simple configuration is proposed and investigated. The proposed fiber refractometer consists of a full-loop structure of bare high-bend loss singlemode fiber-1060XP, employing the well-known whispering gallery mode (WGM) effect induced by the evanescent wave excitation to measure the refractive index of an external medium. A competitive sensitivity is achieved (average 725.76nm/RIU at a bend diameter of 19.3mm) compared with other fiber-optic sensors, plus benefits resulting from simplicity, low cost and ease of fabrication.

Using Simulation Systems For Decision Support, Andreas Tolk Jan 2010

Using Simulation Systems For Decision Support, Andreas Tolk

Computational Modeling & Simulation Engineering Faculty Publications

This chapter describes the use of simulation systems for decision support in support of real operations, which is the most challenging application domain in the discipline of modeling and simulation. To this end, the systems must be integrated as services into the operational infrastructure. To support discovery, selection, and composition of services, they need to be annotated regarding technical, syntactic, semantic, pragmatic, dynamic, and conceptual categories. The systems themselves must be complete and validated. The data must be obtainable, preferably via common protocols shared with the operational infrastructure. Agents and automated forces must produce situation adequate behavior. If these requirements …

Estimating Information Amount Under Uncertainty: Algorithmic Solvability And Computational Complexity, Vladik Kreinovich, Gang Xiang Jan 2010

Estimating Information Amount Under Uncertainty: Algorithmic Solvability And Computational Complexity, Vladik Kreinovich, Gang Xiang

Departmental Technical Reports (CS)

Measurement results (and, more generally, estimates) are never absolutely accurate: there is always an uncertainty, the actual value x is, in general, different from the estimate X. Sometimes, we know the probability of different values of the estimation error dx=X-x, sometimes, we only know the interval of possible values of dx, sometimes, we have interval bounds on the cdf of dx. To compare different measuring instruments, it is desirable to know which of them brings more information - i.e., it is desirable to gauge the amount of information. For probabilistic uncertainty, this amount of information is described by Shannon's entropy; …

United States Navy: Publications

The ability of the metal reducer Shewanella oneidensis MR-1 to generate electricity in microbial fuel cells (MFCs) depends on the activity of a predicted type IV prepilin peptidase; PilD. Analysis of an S. oneidensis MR-1 pilD mutant indicated that it was deficient in pili production (Msh and type IV) and type II secretion (T2S). The requirement for T2S in metal reduction has been previously identified, but the role of pili remains largely unexplored. To define the role of type IV or Msh pili in electron transfer, mutants that lack one or both pilus biogenesis systems were generated and analyzed; …

Comparison Of Indian Ppp Construction Industry And European Ppp Construction Industry: Process, Thresholds And Implementation, Louis Gunnigan, Renuka Rajput

Conference papers

Abstract Since the 1990’s, there has been a rapid rise of Public Private Partnerships (PPPs) across the world. Governments in developing as well as developed countries are increasingly using this procurement method to bridge the much needed infrastructure gap. PPPs are seen as an important tool for producing an accelerated and larger pipeline of infrastructure investments, and catching up with the infrastructure deficit. Arguably, this is why developed and especially developing countries are very keen on PPP models. This paper will compare the PPP procurement process followed in Europe compared to India and presents a thorough review of literature on …


Non-Planar Diamond Electrodes For Biomedical Neural Sensing And Stimulating, Jeffrey M. Halpern Jan 2010

Non-Planar Diamond Electrodes For Biomedical Neural Sensing And Stimulating, Jeffrey M. Halpern

Chemical Engineering

Abstract

Conductive diamond has exceptional chemical stability, making it an appealing candidate material for long-term medical device implants. This work describes the characterization, and fabrication of four diamond-based neural devices. A previously developed 30 µm diamond-disk in vitro needle electrode was characterized. The device could detect 1 nM concentration analytes in a flow cell using fast scan cyclic voltammetry, but the fabrication was not reproducible. A novel in vitro diamond device was developed with diamond selectively grown at the tip of a hollow quartz capillary, resulting in a 2-4 µm tip diameter. The diamond tip shape and size were geometrically …

The Systemic Correlation Between Mental Models And Sustainable Design: Implications For Engineering Educators, Linda Vanasupa, Roger Burton, Jonathan Stolk, Julie B. Zimmerman, Larry J. Leifer, Paul T. Anastas

Materials Engineering

Many studies have illuminated our understanding of the kinds of competencies and behaviors exhibited by effective designers. Against the backdrop of global challenges made more urgent by unintentional negative impacts of engineered products and systems, however, we are left to deduce that our ways of educating engineering designers is fundamentally flawed. We assert that one can trace the cause of our collective, unintended negative consequences to the mental models of reality that we consciously or unconsciously carry. In this paper, we present the case for developing awareness and facility with mental models. We also suggest an alternate mental model as …

A Comparative Guide To The Western States' Public Trust Doctrines: Public Values, Private Rights, And The Evolution Toward An Ecological Public Trust, Robin Kundis Craig

All In-stream Flows Material

In the arid West, balancing private needs for fresh water to consume against the public values-recreational, aesthetic, and ecological-served by leaving fresh water in situ has tended to favor the private use side. Evidence of this result is both massive and minor, ranging from California's multi-billion-dollar water transportation system,1 to the routine de-watering of the Colorado River so that little to no water reaches the Sea of Cortez,2 to water-related Endangered Species Act lawsuits in dozens of watersheds. 3

A Signal Processing Method To Explore Similarity In Protein Flexibility, Simina Vasilache, Nazanin Mirshahi, Soo-Yeon Ji, James Mottonen, Donald J. Jacobs, Kayvan Najarian

Computer Science Publications

Understanding mechanisms of protein flexibility is of great importance to structural biology. The ability to detect similarities between proteins and their patterns is vital in discovering new information about unknown protein functions. A Distance Constraint Model (DCM) provides a means to generate a variety of flexibility measures based on a given protein structure. Although information about mechanical properties of flexibility is critical for understanding protein function for a given protein, the question of whether certain characteristics are shared across homologous proteins is difficult to assess. For a proper assessment, a quantified measure of similarity is necessary. This paper begins to …
