The module is a generic one, whose aim is to facilitate students in developing a comprehensive proposal for their engineering research project. A team approach was taken to module instruction. Students were assessed (at different stages during the module) by evaluation of a written research proposal planner document, a reflective PowerPoint presentation and a final written research project proposal. The contribution reflects on the module ...


The Generation Of Domestic Electricity Load Profiles Through Markov Chain Modelling, Aidan Duffy, Fintan McLoughlin, Michael Conlon 2010 Dublin Institute of Technology

The Generation Of Domestic Electricity Load Profiles Through Markov Chain Modelling, Aidan Duffy, Fintan Mcloughlin, Michael Conlon

Conference Papers

Micro-generation technologies such as photovoltaics and micro-wind power are becoming increasing popular among homeowners, mainly a result of policy support mechanisms helping to improve cost competiveness as compared to traditional fossil fuel generation. National government strategies to reduce electricity demand generated from fossil fuels and to meet European Union 20/20 targets is driving this change. However, the real performance of these technologies in a domestic setting is not often known as high time resolution models for domestic electricity load profiles are not readily available. As a result, projections in terms of reducing electricity demand and financial paybacks for these ...


Validated Real-Time Energy Models For Small-Scale Grid-Connected Pv-Systems, Lacour Ayompe, Aidan Duffy, Sarah McCormack, Michael Conlon 2010 Dublin Institute of Technology

Validated Real-Time Energy Models For Small-Scale Grid-Connected Pv-Systems, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon

Articles

This paper presents validated real-time energy models for small-scale grid-connected PV-systems suitable for domestic application. The models were used to predict real-time AC power output from a PV system in Dublin, Ireland using 30-min intervals of measured performance data between April 2009 and March 2010. Statistical analysis of the predicted results and measured data highlight possible sources of errors and the limitations and/or adequacy of existing models, to describe the temperature and efficiency of PV-cells and consequently, the accuracy of power prediction models. PV-system AC output power predictions using empirical models for PV-cell temperature and efficiency prediction showed lower ...


Energy-Related Carbon Emissions In Ireland: Scenarios To 2020, Tadhg O'Mahony 2010 Dublin Institute of Technology

Energy-Related Carbon Emissions In Ireland: Scenarios To 2020, Tadhg O'Mahony

Doctoral

The consumption of energy and related carbon emissions are a development challenge requiring analysis and policy insights. Current analysis of future change in Ireland relies on quantitative point forecasts within which accuracy is difficult to achieve. A scenario analysis approach has often been applied with the longer term but is also useful on shorter time-scales. This research applied a combination of decomposition analysis and scenario analysis to identify and analyse the driving forces of change in Ireland historically from 1990-2007 and in the future to 2020. The historical decomposition used the LMDI I technique and was further quantified to 2020 ...


Optimizing And Benchmarking Returnable Container Processes Within An Automotive Distribution System, Camille Chism 2010 Rochester Institute of Technology

Optimizing And Benchmarking Returnable Container Processes Within An Automotive Distribution System, Camille Chism

Theses

An analysis of Reusable Packaging in automobile manufacturing facilities, as well as a comparison to other industries, shows that returnable container systems are not being fully utilized.

In this study, methods to return and track packaging materials for reuse are examined. Issues identified through surveys and interviews are summarized, and a recommendation to more fully utilize systems currently in place is proposed. An evaluation based on utilizing the current system will enable us to assign a cost to current operations, and may support an investment in improved systems and technologies.

Most of the companies surveyed gauge functionality based on whether ...


Implementation Of Physiologic Pressure Conditions In A Blood Vessel Mimic Bioreactor System, Kevin Mark Okarski Mr. 2010 California Polytechnic State University - San Luis Obispo

Implementation Of Physiologic Pressure Conditions In A Blood Vessel Mimic Bioreactor System, Kevin Mark Okarski Mr.

Master's Theses and Project Reports

ABSTRACT

Implementation of Physiologic Pressure Conditions in a Blood Vessel Mimic Bioreactor System

Kevin Mark Okarski

Tissue engineering has traditionally been pursued as a therapeutic science intended for restoring or replacing diseased or damaged biologic tissues or organs. Cal Poly’s Blood Vessel Mimic Laboratory is developing a novel application of tissue engineering as a tool for the preclinical evaluation of intravascular devices. The blood vessel mimic (BVM) system has been previously used to assess the tissue response to deployed stents, but under non-physiologic conditions. Since then, efforts have been made to improve the vessel and bioreactor’s ability to ...


Tribological Comparison Of Traditional And Advanced Firearm Coatings, Greg Boban 2010 California Polytechnic State University - San Luis Obispo

Tribological Comparison Of Traditional And Advanced Firearm Coatings, Greg Boban

Master's Theses and Project Reports

The objective of this project is to find which type of coating has the best performance characteristics for finishing firearms. This is accomplished by measuring and comparing several performance characteristics, such as: adhesion, hardness, wear resistance, friction control, and corrosion resistance. Appearance is not a factor since any exterior coating that is flashy can be subdued or camouflaged with special purpose paints, which have proven durable enough for such purposes. Cost will not be a limiting factor for this experiment, but will be discussed in the conclusion as a secondary concern. This data will be used to identify the best ...


Comparing Discrete Simulation And System Dynamics: Modeling An Anti-Insurgency Influence Operation, Wayne Wakeland, Una E. Medina 2010 Portland State University

Comparing Discrete Simulation And System Dynamics: Modeling An Anti-Insurgency Influence Operation, Wayne Wakeland, Una E. Medina

Systems Science Faculty Publications and Presentations

This paper contrasts the tradeoffs of modeling the same dynamic problem at a micro scale and at a macro scale of analysis: discrete system simulation (DS) versus continuous system simulation or system dynamics (SD). Both are employed to model the influence of entertainment education on terrorist system decay, with implications for field application. Each method optimizes different design, scope/scale, data availability/accuracy, parameter settings, and system sensitivities. Whether the research served by the computer model is applied or theoretical, DS tends to be useful for understand low-level individual unit/step influences on system change over time, whereas SD tends ...


System Dynamics Implementation Of An Extended Brander And Taylor-Like Easter Island Model, Takuro Uehara, Yoko Nagase, Wayne Wakeland 2010 Portland State University

System Dynamics Implementation Of An Extended Brander And Taylor-Like Easter Island Model, Takuro Uehara, Yoko Nagase, Wayne Wakeland

Systems Science Faculty Publications and Presentations

We provide a system dynamics implementation of a dynamic ecological economics model. Dynamic economic models are often constrained to use functions, such as the Cobb-Douglas function, chosen “conveniently” to allow for analytic solutions. The C-D function, however, suffers from its fixed elasticity that does not allow for the substitutability between man-made capital and natural capital to change, which is vital for economic sustainability. Using system dynamics removes this constraint and enables more realistic ecological economics models containing functions not amenable to analytic solution. The base model is the natural resource and population growth model developed by Brander and Taylor (1998 ...


Image-Based Quantification Workflow For Coronary Morphology: A Tool For Use In Next-Generation Bifurcation Stent Design, Sara Marie Nomeland 2010 Marquette University

Image-Based Quantification Workflow For Coronary Morphology: A Tool For Use In Next-Generation Bifurcation Stent Design, Sara Marie Nomeland

Master's Theses (2009 -)

Coronary artery disease (CAD) occurs in ~200,000 bifurcation lesions annually. Treatment of CAD near bends and bifurcations is challenging and a preferred strategy for bifurcation lesions has yet to be established. However, a favorable treatment option may be elucidated by a more thorough understanding of vessel morphology as well as local hemodynamic alterations caused by current stenting approaches. Computational modeling of human arteries offers an attractive way to investigate the relationships between geometry, hemodynamics and vascular disease. Recent developments also make it possible to perform analysis on realistic geometries acquired noninvasively.

The objective of this work was twofold. The ...

Effects Of Chloride Contamination On Coatings Performance, Bobby W. Meade, Sudhir Palle, Theodore Hopwood II, Rick Younce 2010 University of Kentucky

Effects Of Chloride Contamination On Coatings Performance, Bobby W. Meade, Sudhir Palle, Theodore Hopwood Ii, Rick Younce

Kentucky Transportation Center Research Report

Research indicates that chloride concentration as determined by currently available field test methods does not reliably predict protective coating performance on KYTC bridges. Laboratory testing of chloride charged panels also failed to relate chloride concentration to coating performance. The coatings industry provides recommendations for acceptable chloride levels for various exposure conditions but bridges are different than other structural steel and the exposure conditions for bridges are not adequately addressed. Effective chloride remediation strategies and protective coatings that perform best in the presence of chlorides need to be identified.

Fatigue Strength Of Steel Bridge Members With Intersecting Welds, David T. DeLong, Mark D. Bowman 2010 Purdue University

Fatigue Strength Of Steel Bridge Members With Intersecting Welds, David T. Delong, Mark D. Bowman

JTRP Technical Reports

The brittle fracture of the Hoan Bridge in December 2000 highlighted the fracture susceptibility of details containing intersecting welds in steel bridges. Though it is now known that details with intersecting welds should be avoided, many existing bridges in Indiana contain details with intersecting welds. Little experimental data on the fatigue performance of these details exists.

The purpose of this study was to evaluate the fatigue strength of several details commonly found in steel bridges in Indiana that contain intersecting welds. Large-scale experimental fatigue testing were performed using nine steel beams to study the behavior of three basic types of ...


Real Gas Effects In Heated Gas Inflators, Matthew John Zanker 2010 University of Iowa

Real Gas Effects In Heated Gas Inflators, Matthew John Zanker

Theses and Dissertations

Currently, almost all new vehicles are equipped with airbags. A common type of airbag inflator is the Heated Gas Inflator (HGI). These inflators are cylindrical shaped canisters that are filled to very high pressures with a gaseous mixture of fuel and air. The mixture is ignited from one or both ends of the cylinder. The resulting high temperatures from combustion heats the excess air, which is then used to inflate the airbag. Once the mixture is ignited, large pressure waves form, traveling along the length of the tube. These waves, inherent to the design of the inflator, do not allow ...


Regional Lung Function And Mechanics Using Image Registration, Kai Ding 2010 University of Iowa

Regional Lung Function And Mechanics Using Image Registration, Kai Ding

Theses and Dissertations

The main function of the respiratory system is gas exchange. Since many disease or injury conditions can cause biomechanical or material property changes that can alter lung function, there is a great interest in measuring regional lung function and mechanics.

In this thesis, we present a technique that uses multiple respiratory-gated CT images of the lung acquired at different levels of inflation with both breath-hold static scans and retrospectively reconstructed 4D dynamic scans, along with non-rigid 3D image registration, to make local estimates of lung tissue function and mechanics. We validate our technique using anatomical landmarks and functional Xe-CT estimated ...


Multiresolution Analysis For Adaptive Refinement Of Multiphase Flow Computations, Neal Phillip Grieb 2010 University of Iowa

Multiresolution Analysis For Adaptive Refinement Of Multiphase Flow Computations, Neal Phillip Grieb

Theses and Dissertations

Flows around immersed boundaries exhibit many complex, well defined and active dynamical structures. In fact, features such as shock waves, strong vorticity concentrations in shear layers, wakes, or boundary layer regions are critical elements in representing the dynamics of a flow field. In order to capture the correct kinematic and dynamic quantities associated with the fluid flows, one must be able to efficiently refine the computational mesh around areas containing high gradients of pressure, density, velocity, or other suitable flowfield variables that characterize distinct structures. Although there are techniques which utilize simple gradient-based Local Mesh Refinement (LMR) to adapt resolution ...


Work Zone Safety Intervention: Perceptual Countermeasure To Speeding Using Synchronized Warning Lights, Sameer Ahmad Khan 2010 University of Iowa

Work Zone Safety Intervention: Perceptual Countermeasure To Speeding Using Synchronized Warning Lights, Sameer Ahmad Khan

Theses and Dissertations

A driving simulator study of perceptual countermeasures to speeding is described. Perceptual countermeasures (PC) manipulate the drivers' visual scene to help them moderate their driving speed without a conscious deliberation to do so. The use of synchronized warning lights in work zones as a PC is similar to "aero plane runway lights" flashing towards the diver. Based on the literature survey, this effect was postulated to make drivers think they were driving fast at lower vehicular speeds with lesser speed fluctuations. The effect did not achieve statistical significance in reducing mean speeds within work zones to match with the posted ...


Release Of Polychlorinated Biphenyl Congeners In A Contaminated Harbor And Canal, Andres Jose Martinez Araneda 2010 University of Iowa

Release Of Polychlorinated Biphenyl Congeners In A Contaminated Harbor And Canal, Andres Jose Martinez Araneda

Theses and Dissertations

The overall hypothesis of this thesis addresses the release of polychlorinated biphenyls (PCBs) in the sediments of a highly contaminated harbor. I collected, analyzed and quantified PCB congeners in more than 130 samples of air, water and sediment. Then I constructed a chemical fate model as function of chemical concentrations, physical-chemical properties, local meteorological and hydraulic conditions. Indiana Harbor and Ship Canal in East Chicago (IHSC), Indiana, was selected for its expected high levels of PCBs in the sediment and because of future plans for dredging. I found that PCB concentrations in air, water and sediment in this area were ...
