Data Gathering In Cognitive Radio Ad Hoc And Sensor Wireless Networks, Kimberly A. Brown
Data Gathering In Cognitive Radio Ad Hoc And Sensor Wireless Networks, Kimberly A. Brown
Theses and Dissertations
Data gathering is a network communication task in which all of the network’s nodes send their individual messages to a distinguished sink node. In cognitive radio ad hoc and sensor wireless networks (CR-AHSWNs), unlicensed secondary users (SUs) opportunistically use channels when the licensed primary users are not using them. Therefore, the channels available to each SU vary with time and location, which makes the development of data gathering algorithms for CR-AHSWNs challenging. In this thesis, a data gathering protocol for CR-AHSWNs is proposed. The protocol consists of several distributed SU action selection and channel selection algorithms. An algorithm that can …
Conversational Agent: Developing A Model For Intelligent Agents With Transient Emotional States, Angie Dowdell
Conversational Agent: Developing A Model For Intelligent Agents With Transient Emotional States, Angie Dowdell
Theses and Dissertations
The inclusion of human characteristics (i.e., emotions, personality) within an intelligent agent can often increase the effectiveness of information delivery and retrieval. Chat-bots offer a plethora of benefits within an eclectic range of disciplines (e.g., education, medicine, clinical and mental health). Hence, chatbots offer an effective way to observe, assess, and evaluate human communication patterns. Current research aims to develop a computational model for conversational agents with an emotional component to be applied to the army leadership training program that will allow for the examination of interpersonal skills in future research. Overall, the current research explores the application of the …
Automated Essay Evaluation Using Natural Language Processing And Machine Learning, Harshanthi Ghanta
Automated Essay Evaluation Using Natural Language Processing And Machine Learning, Harshanthi Ghanta
Theses and Dissertations
The goal of automated essay evaluation is to assign grades to essays and provide feedback using computers. Automated evaluation is increasingly being used in classrooms and online exams. The aim of this project is to develop machine learning models for performing automated essay scoring and evaluate their performance. In this research, a publicly available essay data set was used to train and test the efficacy of the adopted techniques. Natural language processing techniques were used to extract features from essays in the dataset. Three different existing machine learning algorithms were used on the chosen dataset. The data was divided into …
A Statistical Investigation Of Stock Market Activity And Instances Of Financial Crime, Elizabeth G. Biggs
A Statistical Investigation Of Stock Market Activity And Instances Of Financial Crime, Elizabeth G. Biggs
Theses and Dissertations
This project aims to identify a possible statistical relationship between the stock market and incidences of financial crime in Illinois, Texas, and Utah through big data analysis techniques using data from the FBI’s Federal Bureau of Investigation’s National Incident-Based Reporting System (NIBRS) database. By analyzing the occurrences of financial crime by location, year, and type in relation to the S&P 500’s percent change in close price on the first day of the calendar year, it will be possible to determine if a statistical relationship exists between the two. In addition, regression analysis was performed in order to predict financial crime …
Adapting Financial Technology Standards To Blockchain Platforms, Gabriel Bello
Adapting Financial Technology Standards To Blockchain Platforms, Gabriel Bello
Theses and Dissertations
Traditional payment systems have standards designed to keep transaction data secure, but blockchain systems are not in scope for such security standards. We compare the Payment Application Data Security Standard’s (PA-DSS) applicability towards transaction-supported blockchain platforms to test the standard’s applicability. By highlighting the differences in implementation on traditional and decentralized transaction platforms, we critique and adapt the standards to fit the decentralized model. In two case studies, we analyze the QTUM and Ethereum blockchain platforms’ industry compliance, as their payment platforms support transactions equivalent to that of applications governed by the PA-DSS. We determine QTUM’s and Ethereum’s capabilities to …
Design And Evaluation Of A Wearable System For Facial Privacy, Scott Griffith
Design And Evaluation Of A Wearable System For Facial Privacy, Scott Griffith
Theses and Dissertations
Through the increasingly common use of devices that provide ubiquitous sensor data such as wearables, mobile phones, and Internet-connected devices of the sort, privacy challenges are becoming even more significant. One major challenge that requires more focus is bystanders' privacy, as there are too few solutions that solve the issue. Of the solutions available, many of them do not give bystanders a choice in how their private data is used, Bystanders' privacy has become an afterthought when it comes to data capture in the forms of photographs, videos, voice recordings, etc. and continues to remain that way. This thesis provides …
Curtus: An Nlp Tool To Map Job Skills To Academic Courses, Daniel Rockwell
Curtus: An Nlp Tool To Map Job Skills To Academic Courses, Daniel Rockwell
Theses and Dissertations
Many businesses are burdened with the need to train students for the job instead of finding them prepared for it. Few business leaders feel that colleges prepare students for future jobs from day one. It can be a challenge for colleges to determine if their curricula meet the industry needs. Mapping industry needs to academic courses can be advantageous to both parties as it will allow colleges to be aligned with the industry needs and accordingly satisfy those needs and will allow the industry to hire better prepared graduates. In an attempt to address this, a system prototype that uses …
