A Cloud Interoperability Broker (Cib) For Data Migration In Saas, Hassan Ali, Ramdan Mowad, Amira Farouk

Future Computing and Informatics Journal

Cloud computing is becoming increasingly popular. Information technology market leaders, e.g., Microsoft, Google, and Amazon, are extensively shifting toward cloud-based solutions. However, there is isolation in the cloud implementations provided by the cloud vendors. Limited interoperability can cause one user to adhere to a single cloud provider; thus, a required migration of an application or data from one cloud provider to another may necessitate a significant effort and/or full-cycle redevelopment to fit the new provider's standards and implementation. The ability to move from one cloud vendor to another would be a step toward advancing cloud computing interoperability and increasing customer …

The Character Jar: Trait-Based Facial Feature Generation Software, Angela Shao

Computer Science and Engineering Senior Theses

While AI has come a long way in random facial generation, very limited research has been done on targeted generation. Initial impressions given by faces vary widely depending on the shape and proportions of the features. This project will design a program that manipulates a face shape according to given traits. By using preexisting research on the correlation between facial features and associated characteristics and impressions, the practical uses of facial generation increase many fold. This allows facial generation to be applied to marketing and design, as well as increasing the overall accessibility to any laypersons seeking such applications.

Detection Of Rouge Drones Based On Radio Frequency Classification, Akash V. Gosai, Sachin Shetty

OUR Journal: ODU Undergraduate Research Journal

The current classification of RF signals from the drone is achieved by leveraging raw signal information of a specific band. The modulation scheme that was found prevailing in commercial drones is Orthogonal Frequency Division Multiplexing (OFDM). OFDM can demodulated to provide information about a raw drone signal. This extracted data is coupled with a machine learning algorithm that is used to classify the signal. Testing of this research is needed to identify better equipment and an optimized test scenario that captures quality data that can be used to train a machine learning algorithm.

Galapago!, Kristina Anderson, Kat Hibbert, Mariah Manzano, Catrina Nguyen

Computer Science and Engineering Senior Theses

When traveling to the Galápagos Islands, tourists are unaware of all the Islands have to offer and only visit popular tourist spots. They bring in pests which are damaging to the ecological structure and do not contribute to the local economy. There is very limited Internet services on the Islands and not many online resources to be found. We have created a mobile and web application that show users recommendations for their visit. Because the Galápagos Islands do not have reliable internet connectivity, our application must not rely on connectivity to function. Instead, users will only need to connect once …

Omwanathrive: A Neonatal Survival App, Story Deweese, Tiffany Lee, Samantha Sy, Emily Zhang

Computer Science and Engineering Senior Theses

Uganda’s infant mortality rate is alarmingly high, ranking twenty-first in the world for highest infant mortality; eighty-one babies die within their first month of life each day in Uganda. The UN reports the greatest risk factors are rural location, prematurity, and young impoverished mothers with limited educational opportunities. Thus, young women are giving birth to children before they even learn about how to take care of their newborn infant. Our solution to this problem is in the form of a mobile application called OmwanaThrive: Neonatal Survival App. The purpose of the app is to educate women about how to properly …

Hydrolastic Damping: A Change To The Modern Helmet, Mark Buesa, Ara Moosekian, Michael Simeon, Ian Watts

Mechanical Engineering Senior Theses

High rates of concussion in the NFL suggest that helmet technology is not satisfactory for the athletes, and soft foam padding has dominated the helmet industry since its inception. The team proposed that implementing a fluid-based hydrolastic suspension system in the helmet would reduce the risk of concussions at all levels of competition. After using COMSOL to successfully model fluid flow through the dampers and after physical testing on dampers filled with air and water lead to increased "time to stop" of an average of 240% when compared to traditional foam padding, the team concluded that the dampers showed promise …

In the last years, acoustic word embeddings (AWEs) have gained significant interest in the research community. It applies specifically to the application of acoustic embeddings in the Query-by Example Spoken Term Detection (QbE-STD) search and related word discrimination tasks. It has been shown that AWEs learned for the word or phone classification in one or several languages can outperform approaches that use dynamic time warping (DTW). In this paper, a new method of learning AWEs in the DTW framework is proposed. It employs a multitask triplet neural network to generate the AWEs. The triplet network learns acoustic representations of words …

Development Of Water Coning Control Design Metrics In Naturally Fractured Reservoirs, Samir Prasun

LSU Doctoral Dissertations

Naturally fractured reservoirs (NFRs) with bottom-water are known for their instant water breakthrough and severe water coning that reduces oil recovery. This is because water channels through the highly permeable fractures easily connecting the well to the aquifer bypassing the oil contained in the matrix. Remedial techniques such as producing below critical-oil rate, optimizing the well spacing and installing the downhole water sink (DWS)/ downhole water loop (DWL) technology, have already been successfully tested in single-porosity reservoirs (SPR). However, applicability of these techniques in NFRs are unknown since only a few studies have been performed on their feasibility in NFRs, …
