Temperature Dependence Of A Macrobending Edge Filter Based On A High-Bend Loss Fiber, Pengfei Wang, Ginu Rajan, Yuliya Semenova, Gerald Farrell

Articles

The temperature dependence of a macrobending bare fiber based edge filter is investigated both theoretically and experimentally. The fiber used is a high bend loss fiber, type 1060XP. The experimental results show a good agreement with the proposed theoretical model over a temperature range from 0 to 80oC. It is shown that the strong temperature dependence of a high-bend loss fiber has a significant influence on the performance of a fiber edge filter used in a wavelength measurement application. However it is also concluded that such a temperature dependent performance can be beneficially utilized in a fiber temperature sensing application.

Relaxation Time, Diffusion, And Viscosity Analysis Of Model Asphalt Systems Using Molecular Simulation, Liqun Zhang, Michael L. Greenfield

Chemical Engineering Faculty Publications

Molecular dynamics simulation was used to calculate rotational relaxation time, diffusion coefficient, and zero-shear viscosity for a pure aromatic compound naphthalene and for aromatic and aliphatic components in model asphalt systems over a temperature range of 298–443 K. The model asphalt systems were chosen previously to represent real asphalt. Green–Kubo and Einstein methods were used to estimate viscosity at high temperature 443.15 K. Rotational relaxation times were calculated by nonlinear regression of orientation correlation functions to a modified Kohlrausch–Williams–Watts function. The Vogel–Fulcher–Tammann equation was used to analyze the temperature dependences of relaxation time, viscosity, and diffusion coefficient. The temperature dependences …

The Theory Of Planned Behavior As A Model Of Academic Dishonesty In Engineering And Humanities Undergraduates, Trevor S. Harding, Mathew J. Mayhew, Cynthia J. Finelli, Donald D. Carpenter

Materials Engineering

This study examines the use of a modified form of the Theory of Planned Behavior in understanding the decisions of undergraduate students in engineering and humanities to engage in cheating. We surveyed 527 randomly selected students from three academic institutions. Results supported the use of the model in predicting ethical decision-making regarding cheating. In particular, the model demonstrated how certain variables (gender, discipline, high school cheating, education level, international student status, participation in Greek organizations or other clubs) and moral constructs related to intention to cheat, attitudes toward cheating, perceptions of norms with respect to cheating, and ultimately, cheating behaviors. …

Computer-Based Instruction For Engineering Education In The Developing World, Bradford G. Singley

Theses and Dissertations

Although civil engineers continually develop new ways to solve problems involving water, energy, infrastructure and environmental sustainability, these innovations can take years – or even decades – to reach developing countries. Computer-based instruction has the potential to dramatically decrease this lag time by improving engineering education in the developing world. This paper discusses the development of instructional simulations, based on the theory of model-centered instruction. These simulations can serve as self-paced learning modules, which can be accessed for free over the Internet. A pilot learning module was developed for the United Nations Educational Scientific and Cultural Organization (UNESCO) on the …

A Hybrid First Year Science Course For Engineering Students – Integrating Biology With Chemistry, David Harding, Pauline Schwartz, Jean Nocito-Gobel, Agamemnon Koutsospyros

Civil Engineering Faculty Publications

Biology is playing an increasingly important role in many engineering fields. With the typical engineering program already having a high credit hour requirement, the question becomes, how to best integrate biology concepts into a packed engineering curriculum. A typical biology course is not likely to introduce the important concepts of biology to engineering students. The solution here is to develop a hybrid course that integrates chemistry and biology. In the course, Chemistry with Applications to Biosystems, the concept is to develop a course that integrally links important concepts of chemistry and biology. The course focuses on the areas of biology …

Mesophase Separation And Probe Dynamics In Protein-Polyelectrolyte Coacervates, A. Basak Kayitmazer, Himadri B. Bohidar, Kevin W. Mattison, Arijit Bose, Jayashri Sarkar, Akihito Hashidzume, Paul S. Russo, Werner Jaeger, Paul L. Dubin

Chemical Engineering Faculty Publications

Protein–polyelectrolyte coacervates are self-assembling macroscopically monophasic biomacromolecular fluids whose unique properties arise from transient heterogeneities. The structures of coacervates formed at different conditions of pH and ionic strength from poly(dimethyldiallylammonium chloride) and bovine serum albumin (BSA), were probed using fluorescence recovery after photobleaching. Measurements of self-diffusion in coacervates were carried out using fluorescein-tagged BSA, and similarly tagged Ficoll, a non-interacting branched polysaccharide with the same size as BSA. The results are best explained by temporal and spatial heterogeneities, also inferred from static light scattering and cryo-TEM, which indicate heterogeneous scattering centers of several hundred nm. Taken together with previous dynamic …

Recruitment And Retention: The Role Of The Public Image Of Engineering, Eddie Conlon

Conference papers

This paper presents findings of three surveys conducted with first year students in the Faculty of Engineering in the Dublin Institute of Technology. It focuses on their motivation for studying engineering and the people who influenced the decision to do engineering. It shows there are gaps in the students’ knowledge of their programmes and also between their expectations and their experience of their course. Some proposed areas of action are identified to increase both recruitment and retention. It is argued that projecting an image of engineering as a creative activity would help in addressing recruitment and retention issues.

Engineering Science As Opposed To Natural Science, Eugene Coyle, Mike Murphy, William Grimson

Books/Book chapters

In exploring the epistemology of engineering science, we propose a model of engineering. This model incorporates the goals of engineering, the approach to engineering (also called the engineering method) and the role of experience in engineering. The basis for understanding the nature of engineering science will be explored, and will be contrasted with natural science. To begin, a large-scale engineering project that was successfully completed in Ireland many years ago is discussed - specifically, the development of a megalithic passage tomb as an exemplar of the engineering method in structural design, project management and aesthetics. This exemplar firmly demonstrates that …
