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 …

Development Of A Theoretical Decoupled Stirling Cycle Engine, Barry Cullen, Jim Mcgovern

Conference Papers

The Stirling cycle engine is gaining increasing attention in the current energy market as a clean, quiet and versatile prime mover for use in such situations as solar thermal generation, micro cogeneration and other micro distributed generation situations. A theoretical Stirling cycle engine model is developed. Using a theoretical decoupled engine configuration in which working space swept volume, volume variation, phase angle and dead space ratio are controlled via a black-box electronic controller, a model is developed that is to be used as a tool for analysis of the ideal Stirling cycle engine and the limits on its real world …

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 …

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.

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 …

Implications Of Philosophy For Engineering And Engineering Technology Bachelors Programs, Michael Dyrenfurth, Mike Murphy, William Grimson

Conference papers

This paper raises the question: What is philosophy and then, after describing its branches and school, it extends the definitions to implications for the practice of engineering and engineering technology education. It folds the definitions against the work of engineering faculty. The latter was described as including curriculum development, teaching, mentoring/advising, research/scholarship, and engagement. Sample codes of ethics are shared for engineering technology students and professionals.

Analytical Modeling Of Tree Vibration Generated During Cutting Process, Payman Karvanirabori

Masters Theses 1911 - February 2014

There are several ways to cut down a tree. The piece by piece cutting method is studied in this research. By modeling the cutting process into simple dynamic models and obtaining governing equations of motion of tree and cut piece in each model, the forces during cutting process were calculated. The method was then applied to a set of real data and tree vibrations were compared with field measurements. The study is very rare in the case of the variety of the topics it covers from dynamics and mechanics to finite element modeling of a biological system.

Modelling Behavioural Antecedents Of Inter-Firm Linkages In The Irish Road Freight Industry: An Application Of The Theory Of Planned Behaviour, Eoin Plant

Doctoral

The Irish road haulage industry exhibits a structure dominated by singlevehicle owner-managed operators. This has implications for the Irish economy through reduced efficiency. It is crucial that Ireland’s transport policies sustain its trade-dependent economy and this study can help inform those policies. The European Union has made a commitment to promoting sustainable mobility through advanced transport logistics. One of the principal areas not previously addressed is that of barriers to ollaboration. This thesis initially examines economies of scale within the road freight industry and argues that collaborative networks can aid sustainable transport and increase efficiencies in logistics.

Uniarab: An Universal Machine Translator System For Arabic Based On Role And Reference Grammar, Brian Nolan, Yasser Salem

Conference Papers

This paper presents a machine translation system (Hutchins 2003) called UniArab (Salem, Hensman and Nolan 2008). It is a proof-of-concept system supporting the fundamental aspects of Arabic, such as the parts of speech, agreement and tenses. UniArab is based on the linking algorithm of RRG (syntax to semantics and vice versa). UniArab takes MSA Arabic as input in the native orthography, parses the sentence(s) into a logical meta-representation based on the fully expanded RRG logical structures and, using this, generates perfectly grammatical English output with full agreement and morphological resolution. UniArab utilizes an XML-based implementation of elements of the Role …

Detection Of An So2 Plume Over Sapporo, Japan From The Eruption Of Mt. Kasatochi Using A Balloon Sounding Technique, Gary A. Morris, Jun Hirokawa, Masatomo Fujiwara, Fumio Hasebe, Keisuke Ishida, Nicholay Krotkov, Mark R. Schoeberl, Walter Komhyr, Barry Lefer, James Flynn

Physics and Astronomy Faculty Presentations

During the month of August 2008, 10 ozonesondes were launched from Hokkaido University in Sapporo, Japan as part of a study to examine regional pollution during the Olympic period. Seven of these soundings included a second instrument with a filter designed to remove SO2 from the intake air stream. SO2 interferes with the normal chemistry of the electrochemical cell (ECC) method for ozone detection, with the net result being that each molecule of SO2 registers as minus one molecule of O3. Thus the unfiltered sonde reports [O3] - [SO2] while the filtered sonde reports [O3]. Laboratory tests prior to launch …

Incorporating Spatial Data And Gis To Improve Sea Of Land Use Plans: Opportunities And Limitations: Case Studies In The Republic Of Ireland, Ainhoa Gonzalez Del Campo

Doctoral

This research aimed at establishing whether spatial data and Geographic Information Systems (GIS) can contribute to Strategic Environmental Assessment (SEA). To achieve this, an integrated GISEA approach was developed and applied to a number of spatial planning SEAs in the Republic of Ireland. The practical applicability of the approach was examined, evaluating the potential benefits derived from using spatial data and GIS in SEA and assessing the potential barriers to an effective GIS use. The implementation of the SEA Directive incorporated a new dimension into plan-making by calling for the assessment of potential environmental effects that may derive from implementing …

Conference Papers

This paper describes the implementation of an experimental method of delivery for a module of remote sensing material to second year students on the BSc (Hons) in Geomatics at the Dublin Institute of Technology. The project began as a reaction to poor levels of student engagement and unsatisfactory grades, as well as the requirement to focus more on real-world type problems due to the implementation of a work-placement semester for third year students. Both pedagogical considerations (movement towards formative feedback, interactivity and group-based work) and the effect of technological drivers, such as the popularity of the internet in general and …

Metrology And Proportion In The Ecclesiastical Architecture Of Medieval Ireland, Avril Behan, Rachel Moss

Conference Papers

The aim of this paper is to examine the extent to which detailed empirical analysis of the metrology and proportional systems used in the design of Irish ecclesiastical architecture can be analysed to provide historical information not otherwise available. Focussing on a relatively limited sample of window tracery designs as a case study, it will first set out to establish what, if any, systems were in use, and then what light these might shed on the background, training and work practices of the masons, and, by association, the patrons responsible for employing them.

Ice Nucleation And Overseeding Of Ice In Volcanic Clouds, Adam J. Durant, R. A. Shaw, William I. Rose, Y. Mi, G. G. J. Ernst

Department of Geological and Mining Engineering and Sciences Publications

Water is the dominant component of volcanic gas emissions, and water phase transformations, including the formation of ice, can be significant in the dynamics of volcanic clouds. The effectiveness of volcanic ash particles as ice-forming nuclei (IN) is poorly understood and the sparse data that exist for volcanic ash IN have been interpreted in the context of meteorological, rather than volcanic clouds. In this study, single-particle freezing experiments were carried out to investigate the effect of ash particle composition and surface area on water drop freezing temperature. Measured freezing temperatures show only weak correlations with ash IN composition and surface …
