Multi-Modal Aerial Object Detection For Enhanced Airport Safety, Joel Samu

Discovery Day - Daytona Beach

The rise of small unmanned aerial systems (sUAS) near airports presents growing safety risks, including mid-air collisions, operational disruptions, and security threats. Current detection systems, such as radar and optical tracking, struggle to reliably identify and classify aerial — particularly non-cooperative drones — under variable operational conditions.

This research proposes a multi-modal aerial object detection system that combines six sensor modalities to enable real-time surveillance. By integrating sensor fusion and machine learning (ML), the system aims to improve detection and classification accuracy, reduce false positives, and support Real-time Decision-making for airport safety personnel. The research aims to evaluate system performance …

Corrosion Behavior Of Mgtizn And Mg4tizn Alloys After Ball Milling And Subsequent Spark Plasma Sintering, Alexander Helmer, Rahul Agrawal, Manoj Mugale, Tushar Borkar, Rajeev Gupta

Mechanical Engineering Faculty Publications

Magnesium-containing multi-principal element alloys (MPEAs) are promising for lightweight applications due to their low density, high specific strength, and biocompatibility. This study examines two Mg-Ti-Zn alloy compositions, equal molar MgTiZn (TZ) and Mg4TiZn (4TZ), synthesized via ball milling followed by spark plasma sintering, focusing on their microstructures and corrosion behaviors. X-ray diffraction and transmission electron microscopy revealed the formation of intermetallic phases, including Ti2Zn and Mg21Zn25 in TZ, while 4TZ exhibited a predominantly Mg-rich phase. Potentiodynamic polarization and immersion tests in 0.1 M NaCl solution showed that both alloys had good corrosion resistance, with values of 3.65 +/- 0.65 mu …

Oscillatory Flow Improves Hydrodynamic Ordering Of Soft Suspensions In Rectangular Channels, Paul C. Millett

Mechanical Engineering Faculty Publications and Presentations

A computational study is presented that examines the hydrodynamic ordering of soft-particle suspensions within rectangular channels undergoing both steady and oscillatory flow. In these conditions, particles assemble into one-dimensional train-like configurations aligned in the flow direction. The results indicate that oscillatory flow facilitates a significant improvement in the ordering process, particularly for the assembly of multiple side-by-side trains within the channel. Several key parameters are systematically varied, including the Wolmersley number (Wo) representing the oscillatory frequency, the capillary number (Ca) representing the particle deformability, and the particle volume fraction (phi). It is found that optimal ordering occurs for a particular …

Navigating Multiple Virtual Teams: How Variety In Communication Rules Affects Knowledge Sharing, Valerio Incerti, Kelly J. Fadel, Elisa Mattarelli, Fabiola Bertolotti, Francesca Bellesia, Paula Ungureanu, Katherine M. Chudoba

Faculty Research, Scholarly, and Creative Activity

In contemporary workplaces, individuals are often members of more than one virtual team at a time, that is, they experience multiple virtual team membership (MVTM), and they are subjected to context variety due to different rules across their teams. The aim of this paper is to understand the relationship between context variety related to communication rules and knowledge sharing in situations of MVTM. We propose that context variety and switching between teams negatively affect the individual capability to acquire and provide knowledge resources in a team, due in part to an increased perception of role overload. Through an experimental study, …

Nongovernmental Organizations In The Design And Implementation Of Social Forestry Programs In Indonesia: Interests, Power And Strategies, Arsad Ragandhi, Agus Heruanto Hadna, Setiadi Setiadi, Ahmad Maryudi

Forest and Society

Many social forestry projects have failed to produce expected outcomes. In many cases, they do not suit specific local contexts, problems, and needs because they only articulate the interests of powerful actors outside local communities. In this study, we examine how nongovernmental organizations (NGOs) affect social forestry implementation. In many cases, NGOs are characterized as benevolent actors, often claiming to represent voiceless groups, including poor local communities, in the social forestry context. We are specifically interested in analyzing the ways by which the studied NGOs have shaped the implementation of social forestry models in the forests managed by the state …

Salinity And Moisture Influence Co2 And Ch4 Emissions From High-Latitude Coastal Soils, B. N. Barr, K. C. Kelsey, A. J. Leffler, M. Petit Bon, K. H. Beard

Wildland Resources Faculty Publications

Sea level rise and more frequent and larger storms will increase saltwater flooding in coastal terrestrial ecosystems, altering soil-atmosphere CO₂ and CH₄ exchange. Understanding these impacts is particularly relevant in high-latitude coastal soils that hold large carbon stocks but where the interaction of salinity and moisture on greenhouse gas flux remains unexplored. Here, we quantified the effects of salinity and moisture on CO₂ and CH₄ fluxes from low-Arctic coastal soils from three landscape positions (two Wetlands and Upland Tundra) distinguished by elevation, flooding frequency, soil characteristics, and vegetation. We used a full factorial laboratory incubation experiment …

Integrase-Deficient Lentiviral Vector As A Platform For Efficient Crispr/Cas9-Mediated Gene Editing For Mucopolysaccharidosis Iva, Fnu Nidhi, Shunji Tomatsu

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disorder causing systemic skeletal dysplasia due to a deficiency of N-acetyl-galactosamine-6-sulfate sulfatase (GALNS) enzyme activity, leading to the impaired degradation and accumulation of glycosaminoglycans (GAGs), keratan sulfate (KS) and chondroitin-6-sulfate. While treatments such as enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT) are available, they have significant limitations regarding efficacy in skeletal tissues and long-term safety, highlighting the need for more effective therapies. We evaluated a novel gene therapy approach using a dual Integrase-deficient lentiviral vector (IDLV) to deliver an expression cassette that includes human GALNS cDNA and Cas9 sgRNA, …

Automated Analysis Of Tie And Dowel Rods In Concrete Using 3dgpr, Alexander Paul Betancourt

Master's Theses (2009 -)

Dowel bars and tie rods in concrete pavement hold concrete together when they are placed and positioned correctly and according to specifications provided by the federal and state departments of transportation. However, unintentional misalignments and omissions during pavement construction can adversely impact the integrity of pavements, leading to cracks and other types of pavement failure. Analyzing the positions of the dowel bars and tie rods, although crucial, can be tedious and laborious. Ground-penetrating radar (GPR) can be used to detect objects within a material of mostly constant permittivity. When GPR is combined with multiple scans across a road, a three-dimensional …

The results demonstrated high intra-subject repeatability with minimal variation across sessions, underscoring …

Large Bandgap Observed On The Surfaces Of Euzn2As2 Single Crystals, Dejia Kong, Siavash Karbasizadeh, Ganesh Narasimha, Paras Regmi, Chenggang Tao, Chenggang Tao, Sai Mu, Rama Vasudevan, Ian Harrison, Rongying Jin, Zheng Gai

Faculty Publications

EuZn₂As₂ (M = Zn, Cd, In, Sn etc.) is an excellent material system for studying magnetism-tuned topological properties. However, discrepancies exist between experimental data and theoretical calculations regarding the bulk and surface bandgaps. In this work, cleaved EuZn₂As₂ crystals are studied using scanning tunneling microscopy/spectroscopy and density functional theory calculations. Triangular-shaped defect-induced modifications in the local density of states help distinguish between Eu-terminated and AsZn-terminated surfaces. While large bandgaps ( ~1.5 eV at 77 K) are observed on both pristine surfaces, the bandgap size is found to be highly sensitive to local heterogeneity, tending …

In this study, we explored CD4-Superparamagnetic iron oxide nanoparticles (SPION), which is commonly used in magnetic cell sorting, as a potential receptor-mediated, specific CD4+ T cell MRI labeling agent. We optimized the labeling protocol for maximal CD4+ cell labeling and viability. Cell health was confirmed with trypan blue assay, and labeling efficacy was confirmed with Prussian blue staining, transmission electron microscopy, and MRI of labeled cell pellets. Key cell …

Strikes And The Struggle For Democracy, Angela B. Cornell, Ruth Dukes

Comparative Labor Law & Policy Journal

The right to strike is fundamental to the development and maintenance of democratic forms of government. In struggles to construct and defend democratic regimes, strikes, including general strikes, are often an important weapon. In established democracies, the right to strike can aid the spread of democratic decision-making in workplaces and the wider economy, serving indirectly to strengthen participation and confidence in political processes and institutions. And it can underpin systems of collective bargaining that function to narrow income and wealth inequalities, in a manner that is conducive, if not necessary, to the maintenance of democratic government. Wherever the right to …

The Last Human Job: The Work Of Connecting In A Disconnected World By Allison J. Pugh, Princeton University Press, 2024, Karen Levy

Comparative Labor Law & Policy Journal

“I FEEL SO SEEN!” has become a Gen-Z catchphrase for the sense of personal validation when something you experience resonates with your own way of being in the world — say, when you learn that a lyric you’ve always misheard is also misunderstood by someone else, or that a guilty pleasure in which you indulge isn’t unique to you. These days, the phrase is often thrown around light-heartedly online in response to memes or TikTok videos. But the experience of really “being seen” is far from trivial; it’s a form of recognition essential to human functioning and community. Seeing another …

This work investigates the use of the Integrated Spectral Band Ratio (ISBR) method to measure temperature using a new set of gas bands and a new method for collecting, measuring m and converting raw signals to digital temperature data at low cost and high speed (4 Hz). The Pressurized Oxy-Coal (POC) reactor was refurbished and used in this work to simulate turbine inlet conditions. The POC was modified to produce a stable natural gas and air …

Single-Nucleotide Resolution Epitranscriptomic Profiling Uncovers Dynamic M6a Regulation In Bovine Preimplantation Development, Kinga Pajdzik, Noah R Rakestraw, Piyush K Jain, Chuan He, Chenghang Zong, Zongliang Jiang

Faculty, Staff and Students Publications

RNA N6-methyladenosine (m6A) plays a crucial role in regulating gene expression during early embryonic development. However, the m6A dynamics at single-nucleotide resolution in preimplantation development remain uncharacterized, and the functional significance of site specific m6A modifications in key developmental regulators is largely unknown. Here, using SAC-seq, a single-base resolution, antibody-independent m6A profiling method, we generate the first comprehensive m6A landscape in bovine oocytes and preimplantation embryos. We identify a previously uncharacterized m6A site in RPL12 transcript that is essential for embryonic development. Loss of m6A at this site leads to reduced protein synthesis, disrupted expression of translation-related genes, and …

Gamma-ray binaries are luminous in gamma rays, composed of a compact object orbiting a massive companion star. The interaction between these two objects can drive relativistic outflows, either jets or winds, in which particles can be accelerated to energies reaching hundreds of teraelectronvolts (TeV). However, it is still debated where and under which physical conditions particles are accelerated in these objects and ultimately whether protons can be accelerated up to PeV energies. Among the well-known gamma-ray binaries, LS 5039 is a high-mass X-ray binary with an orbital period of 3.9 days that has been observed up to TeV energies by …

Can We Discover Physical Models Using Machine Learning? A Case Study Of Galaxy Sizes, Festa Buçinca-Çupallari, Ariyeh Maller, Viviana Acquaviva, Austen Gabrielpillai, Rachel S. Somerville

Publications and Research

We explore the ability of machine learning methods to discover underlying equations of physics by searching for the equations governing galaxy size in a semianalytic model. This case study allows us to evaluate the process as we know the ground truth. We find that we fail to find an equation to predict galaxy size on the entire data set, but are successful when we separate out disk galaxies where we expect the physics driving galaxy size to be different than in bulge-dominated systems. We are also able to find an equation for bulge size, but not without adding an additional …
