International Journal of Geospatial and Environmental Research

This study evaluated two popular software packages currently used within the natural resources profession to create orthophoto mosaics: Drone2Map and Pix4Dmapper. Of particular concern was how effective these two software packages would perform in creating orthophoto mosaics over a city park in East Texas consisting of forest, open grass, and urban concrete surrounding a lake. Two drone flights over the city park were conducted. One flight was at 76 meters (250 feet) above ground with a single pass configuration. The other flight was at 122 meters (400 feet) above ground with a double pass configuration. Upon the completion of each …

State Of Urbanization In Nepal: The Official Definition And Reality, Keshav Bhattarai, Ambika P. Adhikari, Shiva Gautam

Himalayan Research Papers Archive

Nepali government’s official delineation of several human settlements as new urban areas has been questionable because many important criteria such as urban infrastructure and services, open space, population density and economic viability are not thoroughly analyzed while defining what is urban. Many settlements in Nepal officially defined as urban, often driven by political considerations, are operating in the rural framework forming ruralopolises. This paper analyzes various criteria needed for defining urbanization that are internationally accepted to assess Nepal’s official definition of urban settlements. Urban areas have been expanding in Nepal at the cost of agricultural, forest, and shrubland land uses. …

Current Developmental Challenges In Nepal: How Can The Diaspora Help?, Ambika P. Adhikari

Himalayan Research Papers Archive

Nepal now enjoys a unique opportunity to positively transform the country’s economy and society. The economic activities fueled by remittance, supported by foreign aid, and aided by domestic economic activities such as tourism, trade, and services, including start-ups, are helping increase individual incomes. However, the earnings from remittances, which measure to about 25% of Nepal’s GDP, are spent on consumer goods and not on investments that can generate employment and raise the standards of living. The foreign aid is often donor driven and also not always well managed and wisely spent on national priorities. Further, it is frequently marred by …

Coastal Environments: Mine Discharges And Infringements On Indigenous Peoples’ Rights, Charles Kerfoot, Gary Swain, Luis M. Verissimo, Erin Johnston, Carol Maclennan, Daniel Schneider, Noel Urban

Michigan Tech Publications, Part 2

Over a century ago, copper mills on the Keweenaw Peninsula of Lake Superior sluiced 64 million metric tonnes (MMT) of tailings into coastal waters, creating a metal-rich “halo”. Here we show that relatively small discharges can spread widely in time and space. Mass Mill (2.9 MMT) dumping into Lake Superior also illustrates the complexity of interactions with Indigenous Peoples. A combination of aerial photos, LiDAR, and a microscope technique for distinguishing end-member particles traces the migration of tailings. The clay fraction spread rapidly across Keweenaw Bay and curled into terminal L’Anse Bay, within tribal Reservation boundaries. The coarse stamp sand …

The Relationship Between Water Temperature And Proximity To Surface Urban Heat Islands Within The Lower Chesapeake Bay Watershed For The Summer Of 2019, Sarah Kerner

Student Research Submissions

Surface urban heat islands (SUHIs) are land surfaces with high concentrations of impervious surfaces like roofs, roads, sidewalks and other infrastructures that trap, absorb, and re-emit heat throughout the day/night and typically present higher temperatures than their surrounding rural areas. In this study, I evaluate how presence of and distance to SUHIs are associated with water temperature in the lower Chesapeake Bay watershed for the summer of 2019. When heavy precipitation events occur, flooding creates stormwater runoff, which is exposed to the hotter temperatures in urban areas. This introduces thermal pollution to nearby rivers and streams disrupting aquatic ecosystems. The …

Michigan Tech Publications, Part 2

Fire is the dominant disturbance agent in Alaskan and Canadian boreal ecosystems and releases large amounts of carbon into the atmosphere. Burned area and carbon emissions have been increasing with climate change, which have the potential to alter the carbon balance and shift the region from a historic sink to a source. It is therefore critically important to track the spatiotemporal changes in burned area and fire carbon emissions over time. Here we developed a new burned-area detection algorithm between 2001-2019 across Alaska and Canada at 500 m (meters) resolution that utilizes finer-scale 30 m Landsat imagery to account for …

College of Population Health Faculty Papers

BACKGROUND: Physical activity (PA) is associated with positive health outcomes over the entire life course. Many community-based interventions that promote PA focus on implementing incremental changes to existing facilities and infrastructure. The objective of this study was to determine if such upgrades were associated with increases in children's PA.

METHODS: Two cohorts of 3- to 15-year-old children (n = 599) living in 4 low-income New Jersey cities were followed during 2- to 5-year periods from 2009 to 2017. Data on children's PA were collected at 2 time points (T1 and T2) from each cohort using telephone survey of parents; data …

Association Between Historical Neighborhood Redlining And Cardiovascular Outcomes Among Us Veterans With Atherosclerotic Cardiovascular Diseases, Salil V. Deo, Issam Motairek, Khurram Nasir, Amgad Mentias, Yakov Elgudin, Salim S. Virani, Sanjay Rajagopalan, Sadeer Al-Kindi

Office of the Provost

Importance: In the 1930s, the government-sponsored Home Owners' Loan Corporation (HOLC) established maps of US neighborhoods that identified mortgage risk (grade A [green] characterizing lowest-risk neighborhoods in the US through mechanisms that transcend traditional risk factors to grade D [red] characterizing highest risk). This practice led to disinvestments and segregation in neighborhoods considered redlined. Very few studies have targeted whether there is an association between redlining and cardiovascular disease.
Objective: To evaluate whether redlining is associated with adverse cardiovascular outcomes in US veterans.
Design, setting, and participants: In this longitudinal cohort study, US veterans were followed up (January 1, 2016, …

Automated Pavement Construction Inspection Using Uncrewed Aerial Systems (Uas)—Hot Mixed Asphalt (Hma) Temperature Segregation, Reihaneh Samsami, Amlan Mukherjee, Colin Brooks

Michigan Tech Publications, Part 2

Temperature segregation in Hot Mixed Asphalt (HMA) pavement construction leads to performance problems, such as reduced fatigue life. During construction, Quality Assurance (QA) inspection procedures are required to evaluate the pavement condition and detect the segregated areas. In traditional HMA highway construction inspection processes, temperature differences are investigated manually, by sampling the HMA behind the paver. In these processes, inspectors are required to work adjacent to traffic and alongside moving or backing equipment. These processes do not provide a complete temperature profile of the mat, endanger the inspectors’ safety, and require on-site experienced inspectors. An Uncrewed Aerial System (UAS) enables …

Improving Decision Support Systems With Machine Learning: Identifying Barriers To Adoption, Skye Brugler, Maaz Gardezi, Ali Dadkhah, Donna M. Rizzo, Asim Zia, Sharon A. Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Precision agriculture (PA) has been defined as a “management strategy that gathers, processes and analyzes temporal, spatial and individual data and combines it with other information to support management decisions according to estimated variability for improved resource use efficiency, productivity, quality, profitability and sustainability of agricultural production.” This definition suggests that because PA should simultaneously increase food production and reduce the environmental footprint, the barriers to adoption of PA should be explored. These barriers include: 1) the financial constraints associated with adopting DSS, 2) the hesitancy of farmers to change from their trusted advisor to a computer program often behaves …

Insights On Simulating Summer Warming Of The Great Lakes: Understanding The Behavior Of A Newly Developed Coupled Lake-Atmosphere Modeling System, Miraj Kayastha, Chenfu Huang, Jiali Wang, William J. Pringle, T. C. Chakraborty, Zhao Yang, Robert D. Hetland, Yun Qian, Pengfei Xue

Michigan Tech Publications

The Laurentian Great Lakes are the world's largest freshwater system and regulate the climate of the Great Lakes region, which has been increasingly experiencing climatic, hydrological, and ecological changes. An accurate mechanistic representation of the Great Lakes thermal structure in Regional Climate Models (RCMs) is paramount to studying the climate of this region. Currently, RCMs have primarily represented the Great Lakes through coupled one-dimensional (1D) column lake models; this approach works well for small inland lakes but is unable to resolve the realistic hydrodynamics of the Great Lakes and leads to inaccurate representations of lake surface temperature (LST) that influence …

The Brave New World Of Third Party Location Data, Shelby Brennan, Stephen Coulthart, Brian Nussbaum

Journal of Strategic Security

The use of third-party location data (3PLD)—geospatial data captured by smart devices and sold by ‘data brokers’—for intelligence and investigations is increasing each year. This data source provides opportunities for analysts and decision makers to better understand as well as counter a host of security threats from common criminals to terrorists. However, and like other emerging and potent sources of intelligence like social media intelligence (SOCMINT), 3PLD must also be wielded legitimately by the government. We argue that the in the US context the legal framework surrounding these data is unclear. Due to the legal ambiguity as well as technological …

A Taxonomy Of Radiofrequency Jamming And Spoofing Strategies And Criminal Motives, Tegg Westbrook

Previous research has also overlooked the motivations of other actors using jamming and spoofing devices.

The objective is to identify the most desirable spoofing and jamming strategies, likely targets, and likely motivations. The article finds that (a) previous literature on the subject overlooks a number of non-state actor motives, …

A Robotic System For In-Situ Measurement Of Soil Total Carbon And Nitrogen, Husein Harun

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Surges in the cost of fertilizer in recent times coupled with the environmental effects of their over-application have driven the need for farmers to optimize the amount of fertilizer they apply on the farm. One of the key steps in determining the right amount of fertilizer to apply in a given field is measuring the amount of nutrients present in the soil. To ascertain nutrient deficiencies, most farmers perform wet chemistry analysis of soil samples which requires a lot of time and is expensive. In this research project, a robotic system was designed and developed that could autonomously move to …
