Department of Agricultural and Biological Systems Engineering: Faculty Publications

Tea (Camellia sinensis) has been found as an important medicinal beverage for human which is consumed all over the world. Primarily, the majority of tea is being cultivated in Asia and Africa, however it is commercially produced by more than 60 countries. Though substantial amount is produced, its processing system is still underdeveloped which leads to decrease in export opportunity as well as low monetary value. Moreover, the traditional method of tea grading and sorting is laborious, inefficient, and costly which ultimately produces the low-quality heterogeneous products. Processing and grading of tea granules after drying is very important …

Satellite Technology Applications In Education: Examples From Greece, Yioryos Nardis

Online Journal of Space Communication

In ancient Greece, there was a mechanism for processing space information from the earth. The Antikythera has since been referred to as the world's first (mechanical) computer. In Greece, the Antikythera mechanism was used to fabricate calendars and schedules for seasons of harvesting and for organizing religious festivals. More than two millennia later, the descendants of these early scholars and technicians are still using outer space to educate themselves, but now the mechanism is electronic and digital using software and spaced-based satellites.

The Broadband Satellite System "Ipstar": Applications In Asia-Pacific Region, Masudul Biswas

Online Journal of Space Communication

The increasing trend of data traffic has turned the world into an information society. Even so, a significant portion of the areas and populations of the world have remained outside the flow of data traffic keeping them information-poor. That is why the issue of "digital divide" has popped up. But it is the cost-effectiveness factor of delivering systems that has guided the changes taking place in information and communication technologies that will ultimately benefit the end users.

The ability to produce outer membrane projections in the form of tubular membrane extensions (MEs) and membrane vesicles (MVs) is a widespread phenomenon among diderm bacteria. Despite this, our knowledge of the ultrastructure of these extensions and their associated protein complexes remains limited. Here, we surveyed the ultrastructure and formation of MEs and MVs, and their associated protein complexes, in tens of thousands of electron cryo-tomograms of ~90 bacterial species that we have collected for various projects over the past 15 years (Jensen lab database), in addition to data generated in the Briegel lab. We identified outer MEs and MVs …

Performance Improvement Through Better Understanding Of Supply Chain Resilience, Amanda L. Femano

Theses and Dissertations

Businesses operate every day in a disruptive environment. Supply and demand uncertainty, natural disasters, global pandemics, and mishaps can all cause chaos to a supply chain’s flow. It is impossible to predict every disruption a supply chain may encounter. The best an organization can do to protect network performance is to build resilience in the supply chain and life-blood of its operations. Ensuring that a supply chain has the proper built-in mechanisms to resist and recover from disruptions is referred to as Supply Chain Resilience (SCR). While it is generally agreed that SCR can be improved through the implementation of …

Subnational Map Of Poverty Generated From Remote-Sensing Data In Africa: Using Machine Learning Models And Advanced Regression Methods For Poverty Estimation, Lionel N. Hanke

Master's Theses

According to the 2020 poverty estimates from the World Bank, it is estimated that 9.1% - 9.4% of the global population lived on less than $1.90 per day. It is estimated that the Covid-19 pandemic further aggravated the issue by pushing more than 1% of the global population below the international poverty line of $1.90 per day (WorldBank, 2020). To provide help and formulate effective measures, poverty needs to be located as exact as possible. For this purpose, it was investigated whether regression methods with aggregated remote-sensing data could be used to estimate poverty in Africa. Therefore, five distinct regression …

The Behaviour Of Rare Earth Elements From South African Coal Fly Ash During Enrichment Processes: Wet, Magnetic Separation And Zeolitisation, Mero Lee Ursula Cornelius, Alechine Emmanuel Ameh, Chuks Paul Eze, Olanrewaju Fatoba, Asel Sartbaeva, Leslie Felicia Petrik

Mining Engineering Faculty Research & Creative Works

Rare earth elements (REEs) are essential raw materials in a variety of industries including clean energy technologies such as electric vehicles and wind turbines. This places an ever-increasing demand on global rare earth element production. Coal fly ash (CFA) possesses appreciable levels of REEs. CFA, a waste by-product of coal combustion, is therefore a readily available source of REEs that does not require mining. CFA valorization to zeolites has been achieved via various synthesis pathways. This study aimed to evaluate one such pathway by monitoring how REEs partition during CFA processing by the wet, magnetic separation process and zeolitisation. South …

In the first study, a multi-stage stochastic programming compartmental model is presented to integrate the uncertain disease progression and the logistics of resource allocation to control a highly contagious infectious disease. The proposed multi-stage stochastic program, which involves various disease growth scenarios, optimizes the distribution of treatment centers and resources while minimizing the total expected …

The Emily Dickinson Machine & Hybrid Poetry Generation, Juliana Shihadeh

Computer Science and Engineering Master's Theses

This thesis introduces EMILY, a machine that creates original poems in the style of renowned poet Emily Dickinson. Dickinson’s succinct and syntactically distinct style with unconventional punctuation makes for an interesting challenge for automated poetry creation. Furthermore, we adapt EMILY to answer the following hypothetical question: What if Emily Dickinson had collaborated with another poet from a different time period? To this end, we introduce Hybrid Generative Poetry, which simultaneously integrates poetic elements from multiple poets. Using two distinct approaches to Hybrid Poetry generation, we create poetry in the combined styles of Emily Dickinson and Robert Frost. User studies are …

Flow Behavior Of Granular Soil And Impounded Fly Ash Slurries, Nuzhath Fatema

Dissertations - ALL

Failure of an embankment dam around mine tailings and coal ash slurry impoundments typically results in a fast-moving flow of toxic waste that can carry for several miles with disastrous consequence. The most recent catastrophic tailing-dam failure took place on 25 January 2019, at Brumadinho, Brazil, where the resultant tailings flow killed at least 232 people. A similar impoundment failure also occurred in 2008 at the TVA Kingston fossil power plant in Tennessee, USA, where coal combustion residuals such as fly ash and bottom ash were stored in the impoundments. The catastrophic failure at Kingston released 4.2 million m3 of …

Assessing Risk At The National Strategic Level: Visualization Tools For Military Planners, Wade A. Germann, Heather S. Gregg

The US Army War College Quarterly: Parameters

The reemergence of great power competition, conflict with near-peer competitor states below the level of armed conflict, and persisting threats from nonstate actors with transnational ambitions and global reach pose challenges for strategists planning, executing, and assessing military operations and strategy. Building on current visualization tools, two proposed models—the National Strategic Risk Abacus and the National Strategic Risk Radar Chart—address these challenges and better depict how the US military may inadvertently contribute to risk at the national strategic level.

Great (Soft) Power Competition: Us And Chinese Efforts In Global Health Engagement, Michael W. Wissemann

The US Army War College Quarterly: Parameters

Global health engagement, an underutilized strategy rooted in the strengths of soft power persuasion, can lead to more military-to-military cooperation training, help establish relationships that can be relied on when crises develop, stabilize fragile states, and deny violent extremist organizations space for recruiting and operations. Examining Chinese efforts worldwide to curry favor and influence and the challenges posed by the COVID-19 pandemic, this article shows health as a medium is a very compelling and advantageous whole-of-government approach to national security policy concerns.

The Challenges Of Applying Computational Legal Analysis To Mhealth Security And Privacy Regulations, Brian Tung

McKelvey School of Engineering Graduate Student Theses & Dissertations

As our world has grown in complexity, so have our laws. By one measure, the United States Code has grown over 30x as long since 1935, and the 186,000-page Code of Federal Regulations has grown almost 10x in length since 1938. Our growing legal system is too complicated; it’s impossible for people to know all the laws that apply to them. However, people are still subject to the law, even if they are unfamiliar with it. Therein lies the need for computational legal analysis. Tools of computation (e.g., data visualization, algorithms, and artificial intelligence) have the potential to transform civic …

Towards Creating Smart Cities In Nepal, Ambika P. Adhikari, Keshav Bhattarai

Himalayan Research Papers Archive

Many urban centers in the world are seeking to become smart cities. Nepali city leaders are also aspiring to make their cities smart. A smart city basically has clever improvements made in three sectors of its operations: technological, human, and institutional. Globally, many cities have recently made impressive enhancements in at least one or more of these areas. Nepal’s National Planning Commission (NPC) in 2016 had released a concept paper on smart cities for Nepal, defining smart cities as sustainable, information and technology-based, with high quality services and replicable (NPC 2016). As most Nepali cities still operate with limited infrastructure, …
