Development Of A Framework For The Assessment Of The Role And Impact Of Technology On The Public Procurement Process: An Irish Health Sector Study, Paul Davis

Doctoral

This thesis sets out to examine how the role and impact of technology, in the context of the public procurement process, can be assessed by addressing it as a single bounded structural entity. The thesis specifically examines the procurement process in the Irish Health Sector. This thesis takes the view that context for the procurement process is critical and that adopting a structuration approach to the examination of the process allows for a greater understanding of the role of technology. The thesis is built around a thematic structure which examines the changing relationship between information technology systems and organisational structure. …

Solar Cell Efficiency Enhancement Through Down-Shifting And Up-Converting Layers: The Ephocell Project: Luminescent Downshifting Quantum Yield Measurements, M. Kennedy, L. Aubouy, D. Gutiérrez-Tauste, A. Jorge, M. Faccini, G. Noriega, M. Di Lorenzo, M. Cocca, M. Avella, M. Errico, G. Gentile, John Doran, Brian Norton, S. Baluschev, J. Bistué Guardiola, A. Robles Molina, J. Puigdollers, C. Voz, S. Daren, F. Tsvetkov, A. Pashov

Conference Papers

Organic cells and dye-sensitized cells developed to-date have a narrow active absorption range, relative to the spectral range of the available solar resource. Their efficiency could be significantly enhanced through a process of down-shifting (DS) and up-conversion of non-absorbable photons converting them to photons better matching the spectral response of the particular solar cell. The DS molecules must exhibit a large Stokes shift and high luminescent quantum yield when incorporated in the downshifting polymer layer. In this paper, the QY of a downshifting Europium (III) complex in solution is determined using two distinct experimental techniques. The QY is measured for …

Broadening Ethics Teaching In Engineering: Beyond The Individualistic Approach, Eddie Conlon, H. Zandvoort

Articles

There is a widespread approach to the teaching of ethics to engineering students in which the exclusive focus is on engineers as individual agents and the broader context in which they do their work is ignored. Although this approach has frequently been criticised in the literature, it persists on a wide scale, as can be inferred from accounts in the educational literature and from the contents of widely used textbooks in engineering ethics. In this contribution we intend to: (1) Restate why the individualistic approach to the teaching of ethics to engineering students is inadequate in view of preparing them …

Experimental Study Of Blast Resistant Glazing System Response To Explosive Loading, William Chad Wedding

University of Kentucky Master's Theses

This thesis recounts the experimental study of the dynamic response of a blast resistant glazing system to explosive loading. A combination of triaxial force sensors, pressure gauges, and laser displacement gauges capture the response in detail over a wide range of scenarios. The scenarios include low level blast loading to characterize the reaction at points around the perimeter of the window, moderate level blast loading to examine the repeatability of the blast scenario, and high level blast loading to capture the response during failure as the tensile membrane forms. The scenarios are modeled via an analytical Single-Degree-of-Freedom model as well …

Fusion Of Sources Of Evidence With Different Importances And Reliabilities, Florentin Smarandache, Jean Dezert, J.M. Tacnet

Branch Mathematics and Statistics Faculty and Staff Publications

This paper presents a new approach for combining sources of evidences with different importances and reliabilities. Usually, the combination of sources of evidences with different reliabilities is done by the classical Shafer’s discounting approach. Therefore, to consider unequal importances of sources, if any, a similar reliability discounting process is generally used, making no difference between the notion of importance and reliability. In fact, in multicriteria decision context, these notions should be clearly distinguished. This paper shows how this can be done and we provide simple examples to show the differences between both solutions for managing importances and reliabilities of sources. …

Creating Insanity In Learning Systems: Addressing Ambiguity Effects Of Predicting Non-Linear Continuous Valued Functions With Reconstructabilty Analysis From Large Categorically Valued Input Data Sets, William D. Eisenhauer

Systems Science Friday Noon Seminar Series

Being told to give two different, and potentially counter, responses to the same stimulus can set up a double bind in humans, leading to a type of insanity. So what how do you deal with it when it comes up quite frequently in modeling through simplification and removal of predictive variables?

In his current dissertation research Ike Eisenhauer is using reconstructability analysis to implement K-System, U-System, and B-System approaches to predict a continuously valued function through discrete categorically valued input variables [e.g. textual data]. One of the key issues is how to address the inability of K-Systems and U-Systems to …

Candidate masks were found by asking customers what they like in rental masks, interviewing other paintball field owners, and referring to the online paintball community. Three candidate masks were found, the V-Force Vantage, JT Alpha, and Kingman java paintball masks. These masks were compared to the currently used rental masks, the V-Force Armor. Customers were surveyed to find out …

Solder Qwik Pentm, Katherine E. Robbins

Industrial and Manufacturing Engineering

Electronics soldering is a technique used frequently in the manufacturing of Printed

Circuit Boards (PCB) to attach small electronic parts or wires together. Often times

the need to remove a solder joint arises; this is known as desoldering. Solder wick,

fine braided copper wire infused with rosin, is one of the most effective ways to

desolder because it results in the cleanest joints. Currently using solder wick

involves several time consuming and somewhat awkward steps. This report will

cover the process behind designing, manufacturing, and testing a new ergonomic,

dispenser for solder wick that can be used with one hand. …

Microwave-Assisted Synthesis Of Zno Micro-Javelins, Suresh Pillai, Declan Mccormack, John M. Kelly, Sibu C. Padmanabhan

Articles

The microwave (MW)-assisted formation of ZnO micro-javelins from zinc nitrate and urea in aqueous solution is described. The particles (named as ‘micro-javelins’ because of their high aspect ratio and needle-like tips) grow hexagonally with well-defined facets in the h0110i direction and pointed tips in (0001) direction. Powder X-ray diffraction patterns show the appearance of a strikingly dominant (1000) orientation. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations reveal the morphological evolution of these hexagonal ZnO particles with time. The effect of precursor concentrations, counterion type andMWirradiation power and their consequent influence on pH and Zn2+ ion concentration are …

Anomaly Detection In Hyperspectral Imagery: Comparison Of Methods Using Diurnal And Seasonal Data, Patrick C. Hytla, Russell C. Hardie, Michael T. Eismann, Joseph Meola

Electrical and Computer Engineering Faculty Publications

The use of hyperspectral imaging is a fast growing field with many applications in the civilian, commercial and military sectors. Hyperspectral images are typically composed of many spectral bands in the visible and infrared regions of the electromagnetic spectrum and have the potential to deliver a great deal of information about a remotely sensed scene. One area of interest regarding hyperspectral images is anomaly detection, or the ability to find spectral outliers within a complex background in a scene with no a priori information about the scene or its specific contents. Anomaly detectors typically operate by creating a statistical background …

Development Of Guidelines For Deformable And Rigid Switch In Ls-Dyna Simulation, Ling Zhu

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

LS-Dyna simulations have been widely used in research and design to reduce fiscal and time costs. In order to improve the simulation’s efficiency, the components which experience negligible deformations are usually modeled as rigid bodies. However, the use of rigid bodies is always restricted. Though the use of more rigid bodies can save computing resources for a particular simulation, less rigid bodies are preferred for building a model in order to broaden its applications. Meanwhile, if a simulation task has multiple events, the application of rigid bodies in the particular simulation is always minimized so that it can satisfy all …

Sustainable Design: A Case Study In Energy Systems, Eugene Coyle, Marek Rebow

Books/Book chapters

Since the publication of the UN climate report in 2007, most countries now agree that recent climate change has occurred as a result of human intervention and that it will require fast and profound measures to reduce this negative imprint imposed upon nature. Central to this is the need to radically reduce CO2 emissions resulting from combustion of carbon-based energy resources to meet global energy demands. Greater measures must be taken to develop new non-combustion based technologies, in addition to using low-carbon energy resources. Increasing energy efficiency and using energy wisely will also feature in reducing emissions. Sustain-able Energy is …

Sustainable Fitness Centers, Matthew Mockaitis

Renée Crown University Honors Thesis Projects - All

The world is in the midst of an energy crisis and it is only going to get worse. World energy consumption rates are increasing by the day; meanwhile, the amount of available natural resources to generate energy is decreasing at impressive rates. In addition, humans are becoming more aware and educated about the vast impact that their daily lives have on the environment. Scientists have discovered that the earth has been gradually warming over the past few decades. Natural cycles within the earth’s climate, at this time, cannot fully explain the relatively large increases in surface temperature in such a …

Digital Supply Chains: Towards A Framework For Software Distribution, Colm Ryan, Claudia-Maria Wagner, Edward Sweeney, Emilio Esposito, Pietro Evangelista

Conference papers

This paper assesses the effect of non-physicality of a digital product - software - on SCM practice. A number of in-depth, one-on-one interviews were held in 8 software companies that predominantly supply to enterprise customers on a global scale. The aim was to explore distribution challenges within software supply chains and how companies are addressing these challenges. The research has identified three different classes of software distribution models: One, which tends to rely on traditional physical infrastructures and paradigms, and two others that better exploit the properties of the digital products.

Shielding Effectiveness Of Superalloy, Aluminum, And Mumetal Shielding Tapes, Cindy Suit Cheung

Master's Theses

Using MIL-HDBK-419A, MATLAB and Nomographs, Shielding Effectiveness for the Magnetic Field, Electric Field, and Plane Wave were calculated over a frequency range from 10 Hz to 1 GHz. The three shielding tapes used included superalloy, aluminum, and mumetal. Calculations for Shielding Effectiveness involve the computation of Absorption Loss, Reflection Loss, and Re-Reflection Correction Factor. From the outcome of the calculations, it was suitable to conclude that all three metals fulfill the 40 dB Shielding Effectiveness requirements for SGEMP fields for frequencies greater or equal to 1 MHz. Accordingly, all three shielding tapes provide at least 40 dB of shielding to …

Hydrometeor-Enhanced Tephra Sedimentation: Constraints From The 18 May 1980 Eruption Of Mount St. Helens, Adam J. Durant, William I. Rose, A. M. Sarna-Wojcicki, S. Carey, A. C. M. Volentik

Department of Geological and Mining Engineering and Sciences Publications

Uncertainty remains on the origin of distal mass deposition maxima observed in many recent tephra fall deposits. In this study the link between ash aggregation and the formation of distal mass deposition maxima is investigated through reanalysis of tephra fallout from the Mount St. Helens 18 May 1980 (MSH80) eruption. In addition, we collate all the data needed to model distal ash sedimentation from the MSH80 eruption cloud. Four particle size subpopulations were present in distal fallout with modes at 2.2 Φ, 4.2 Φ, 5.9 Φ, and 8.3 Φ. Settling rates of the coarsest subpopulation closely matched predicted single-particle terminal …
