Analysis Of Autonomous Unmanned Aerial Systems Based On Operational Scenarios Using Value Modelling, Akash Vidyadharan, Robert Philpott Iii, Benjamin J. Kwasa, Christina L. Bloebaum

Engineering Management and Systems Engineering Faculty Research & Creative Works

In recent years, the use of UAS (Unmanned Aerial Systems) has moved beyond the realm of military operations and has made its way into the hands of consumers and commercial industries. Although the applications of UAS in commercial industries are virtually endless, there are many issues regarding their operations that need to be considered before these valuable pieces of equipment are allowed for widespread civil use. Currently, UAS operations in the public domain are guided and controlled by the FAA Part 107 rules after overwhelming public pressure caused by the earlier 333 exemption. In order to approach such larger issues, …

Archaeological Investigation Of An Iron Age Fortress On Dana Island, Turkey, Nathan C. Mcburnett

Purdue GIS Day

In this project, the Bogsak Archaeological survey team investigated a fortress on the northern crest of the mountain on Dana Island, located just off the coast of Turkey in the Rough Cilician Region. Although the interior remains of the fortress, consisting of a large number of ceramics and architectural features such as a basilica, were dated to the Late Roman Era, we found that the fortress itself actually predates this. Based on ceramic remains being used as aggregate in the fortress wall, the team was able to date the fortress itself to the Iron Age (Classical Era). GIS software was …

Using Gis To Determine Locations For Safety Improvements, Mario Romero, Etienne Tino Atisso, Taojun Wang, Laura Slusher, Andrew Tarko

Purdue GIS Day

Crash location is a critical piece of information for any type of safety-related analysis; however, there is often a high percentage of error in crash latitude and longitude coordinates. Currently, a time-consuming, manual process is used in Indiana to correct faulty crash location coordinates. The Crash Location Improvement Program (CLIP) is a tool developed by the Purdue University Center for Road Safety, with support from Indiana LTAP, which allows users to quickly and easily identify and correct crash coordinates, allowing for a more accurate safety analysis. After correcting the coordinates, crash location maps, heat maps, and other visualization tools are …

Spatial Analysis Of Landfills In Respect To Flood Events And Sea-Level Rise Using Arcgis Pro, Benjamin S. Taylor, Songlin Fei

Purdue GIS Day

"Recently in the news, media coverage of flood events has garnered attention due to tropical storms like Hurricane Harvey and the costly damages that resulted. Under climate change, events like sea-level rise (SLR) and flooding are projected to increase which threaten infrastructure, making it necessary for proper planning before, during, and after installation of landfills to mitigate risk. Studies in Austria and the UK have revealed that many landfills are located in flood zones in addition to coastal areas affected by coastal erosion. In the United States, there have been minimal analysis’ on landfill locations related to flood events and …

Earthquake-Induced Collapsed Building Detection With Vhr Synthetic Aperture Radar Images, Fan Wu, Jie Shan, Chao Wang

Purdue GIS Day

"Compared with optical sensors, Synthetic Aperture Radar (SAR) can provide important damage information due to its ability to map areas affected by earthquakes independently from weather conditions and solar illumination. In 2013, a new TerraSAR-X mode named staring spotlight (ST), whose azimuth resolution was improved to 0.24 m, was introduced for various applications. This very high resolution (VHR) data source made it possible to extract detailed information from individual buildings.

We present a new concept for individual building damage assessment using a post-event sub-meter VHR SAR image and a building footprint map. With the building footprint map, the original footprints …

The Geopolitics Of Rare Earth Elements: Emerging Challenge For U.S. National Security And Economics, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

Rare earth elements (REE) contain unique chemical and physical properties such as lanthanum, are found in small concentrations, need extensive precise processes to separate, and are critical components of modern technologies such as laser guidance systems, personal electronics such as IPhones, satellites, and military weapons systems as varied as Virginia-class fast attack submarines, DDG- 51 Aegis destroyers, the F-35 Joint Strike Fighter, and precision guided munitions. The U.S. has some rare earth resources, but is heavily dependent on access to them from countries as varied as Afghanistan, Bolivia, and China. Losing access to these resources would have significant adverse economic, …

Precise Dating Of The Middle-To-Upper Paleolithic Transition In Murcia (Spain) Supports Late Neandertal Persistence In Iberia, João Zilhão, Daniela Anesin, Thierry Aubry

KIP Articles

The late persistence in Southern Iberia of a Neandertal-associated Middle Paleolithic is supported by the archeological stratigraphy and the radiocarbon and luminescence dating of three newly excavated localities in the Mula basin of Murcia (Spain). At Cueva Antón, Mousterian layer I-k can be no more than 37,100 years-old. At La Boja, the basal Aurignacian can be no less than 36,500 years-old. The regional Middle-to-Upper Paleolithic transition process is thereby bounded to the first half of the 37th millennium Before Present, in agreement with evidence from Andalusia, Gibraltar and Portugal. This chronology represents a lag of minimally 3000 years with the …

Terrorist Sanctuary In The Sahara: A Case Study, Joseph Guido Lieutenant Colonel

Books, Monographs & Collaborative Studies

The idea to deny sanctuary to terrorist groups lies at the heart of contemporary U.S. counterterrorism strategy. Violent extremist organizations in North Africa, most notably the group al-Qaeda in the Islamic Maghreb (AQIM), have used remote and sparsely populated areas in the Sahara for protection from security forces to perform a range of activities such as training, planning, and logistics in order to conduct terrorist operations like kidnapping, murder, and bombing. Even after 16 years since the September 11 attacks and the resources dedicated to efforts to deny sanctuary, the concept of sanctuary remains largely unexplored. To deny sanctuary requires …

The Role Of Social Anarchism And Geography In Constructing A Radical Agenda: A Response To David Harvey, Martha A. Ackelsberg, Myrna Margulies Breitbart

Study of Women, Gender, & Sexuality: Faculty Publications

David Harvey’s response to Simon Springer (2014) raises important questions about the places from which to draw ideas for a radical geography agenda. Nevertheless, Harvey ignores critical contributions that social anarchists (including social geographers) have made to understanding both the theory and practice of social transformation. We draw on studies of the anarchist movement in Spain before and during the Spanish Civil War to explore some of what social anarchism has to contribute to geography and contemporary struggles for a more equitable society.

Modeling Check-In Behavior With Geographical Neighborhood Influence Of Venues, Thanh Nam Doan, Ee Peng Lim

Research Collection School Of Computing and Information Systems

With many users adopting location-based social networks (LBSNs) to share their daily activities, LBSNs become a gold mine for researchers to study human check-in behavior. Modeling such behavior can benefit many useful applications such as urban planning and location-aware recommender systems. Unlike previous studies [4,6,12,17] that focus on the effect of distance on users checking in venues, we consider two venue-specific effects of geographical neighborhood influence, namely, spatial homophily and neighborhood competition. The former refers to the fact that venues share more common features with their spatial neighbors, while the latter captures the rivalry of a venue and its nearby …

From Local To Global: The Role Of Interdisciplinary Place-Based Research In Teaching Environmental Economics, Sean P. Macdonald

Publications and Research

This chapter examines the value of student engagement in interdisciplinary place-based research - where the exploration of “place” assumes a central component of students’ semester research projects in an undergraduate Environmental Economics class. It considers the benefits of teaching from an interdisciplinary perspective while employing the resources of the local community as a laboratory where students engage in research linked to place - the local community, urban space or a virtual location - encouraging students to make meaningful connections between the theoretical study of local and global environmental problems and the actual observation and investigation of those challenges in real …

This thesis addresses training the Thai national leadership in discipleship and leadership qualities to develop a church planting movement with the main goal of evangelizing the unreached people groups throughout the countries of China, Vietnam, Laos, Thailand and Myanmar. The Thai have become dependent on foreign funds and though they are an independent people, they are beginning to realize that there are strings attached—with money comes control. The model will be built around a sustainable farm, which will help in developing vocational skills in order to become indigenous and autonomous. In this thesis it is my purpose to present a …

Discussion On ‘An Enigmatic Echinoid Spine From South Devon, Uk: Devonian Or Cretaceous?’, Proceedings Of The Yorkshire Geological Society , 61, 165–167, Mb Hart

School of Geography, Earth and Environmental Sciences

The echinoid spine described by Donovan & Fearnhead (2017) is reportedly from close to the famous Wolborough Quarry [SX 852704], which is located just to the SW of Newton Abbot in south Devon. The Middle Devonian limestones of this quarry have been described by Scrutton (1978), Leveridge et al. (2003), Leveridge (2011) and Wilmut et al. (2014). As indicated by the authors, and previous research, cherts are exceedingly rare in these limestones.

Scaling Dissolved Nutrient Removal In River Networks: A Comparative Modeling Investigation, Sheng Ye, Alexander J. Reisinger, Jennifer L. Tank, Michelle A. Baker, Robert O. Hall, Emma J. Rosi, Murugesu Sivapalan

Biology Faculty Publications

Along the river network, water, sediment, and nutrients are transported, cycled, and altered by coupled hydrological and biogeochemical processes. Our current understanding of the rates and processes controlling the cycling and removal of dissolved inorganic nutrients in river networks is limited due to a lack of empirical measurements in large, (nonwadeable), rivers. The goal of this paper was to develop a coupled hydrological and biogeochemical process model to simulate nutrient uptake at the network scale during summer base flow conditions. The model was parameterized with literature values from headwater streams, and empirical measurements made in 15 rivers with varying hydrological, …

It All Adds Up: Professional Development, Content Knowledge, And Self-Efficacy In Middle School Math Teachers, Wendy Creek

LMU Theses and Dissertations

The math achievement of American students had been stagnant or falling since 2007, according to both national and international measures (NAEP, TIMSS, PISA). While the Common Core State Standards were partially a response to sinking levels of American math proficiency, those standards require a much greater depth of conceptual understanding of mathematics for teachers than previous standards, yet more than half of fifth- through eighth-grade math teachers are not certified to teach math. The federal government and school districts spend millions of dollars on teacher professional development, but little evidence shows what kind of professional development might be the most …

Dry Canal In Iraq And Mutual Growth In International Economic Environment, Salam Jabbar Shahab

Journal of Economics and Administrative Sciences

In this paper, an attempt was made to measure and interpret the impact of several variables on global maritime transport, including: OECD industrial productions, high growth rates of some developing countries, and growth in world GDP. These variables contribute to higher rates of maritime transport revenues of 800 billion dollars annually; in the form of numerical sequences. The dry canal in Iraq was assumed to transfer 99 million tons of goods annually. This was made sure through the economic feasibility of the difference between maritime and land transport through railways. The effect of geographical and anthropological nature of Iraq on …

Finding Faith In Fantasy: Exploring The Chronicles Of Narnia, Harry Potter, And His Dark Materials, Jamie Weston

Selected Honors Theses

Fantasy is often a controversial topic within the Christian community, especially when magic is involved and religious ideals are tested. This controversy is explored and questioned through the advocating of the creative, intellectual, and spiritual qualities of Fantasy that are positive and encouraging for a Christian, and by analyzing the presence and value of these qualities within three famous fantasy series, The Chronicles of Narnia, Harry Potter, and His Dark Materials.

Exploring Historical Empathy In Secondary Education, Melanie Alsene

Selected Honors Theses

This thesis sought to explore the purpose of teaching history, to define historical empathy, to discover if historical empathy is being taught in secondary public schools, and to see what methods of instruction teachers utilize. Research was done by conducting interviews of middle school and high school history teachers from different schools in the area. These interviews sought to find out if teachers could come up with their purpose for learning about history, if they could define historical empathy, and what methods they utilized to teach historical empathy. Some of the teachers were able to define historical empathy and gave …
