Improving Multi-hop Performance in Multi-radio Multi-channel Mobile Ad-hoc Networks using Data-centric Network-layer Association
Get PDFMobile ad-hoc networks or MANETs are quickly surging into prevalence with the increase in connected devices and unmanned systems. These peer-centric networks do not need network infrastructure such as satellites or cell towers to operate. However, the limitations of wireless communication and non-static peers make implementing these networks non-trivial. In this thesis, we address the incongruity between current wireless communication standards and MANET requirements by controlling multiple wireless radios to form multi-hop links, allowing association of devices at the network layer, and facilitating data-centric communication using Named-data Networking (NDN). We present a plug-and-play cross-layer protocol aimed at sending large amounts of data over a multi-hop peer network using NDN and commodity Wi-Fi radios and evaluate the results against the standard wireless mesh protocol

Assessment in Conversational Intelligent Tutoring Systems: Investigating the Incremental Value of Dialogue Moves in ElectronixTutor
Get PDFIn conversation-based intelligent tutoring systems (ITS), the student is asked challenging questions and there is a multiturn conversation between the computer tutor and the student in constructing an answer to the question. The initial student response after the question provides some information on what the student knows, whereas follow-up contributions of the student presumably extract more of what the student knows. This dissertation investigates the incremental value of follow-up dialogue moves in a conversation-based ITS, specifically ElectronixTutor, a prototype system that has been used in U.S. Navy electronics training. The research addresses two key questions: (1) What is the added value of follow-up dialogue moves in assessing student knowledge beyond initial responses? and (2) How do prior knowledge, student conversational performance, and curriculum-based test outcomes interact to predict the effectiveness of follow-up responses? The dataset that was analyzed consisted of 139 naval trainees on electronics who answered 34 questions with multiturn dialogues. Results show that follow-up dialogue moves significantly improved the assessment of student knowledge. Further, all learners, regardless of prior knowledge, benefited from these follow-up interactions. The study’s implications extend to ITS design, highlighting the importance of incorporating personalized, adaptive feedback based on prior knowledge and leveraging dialogue moves as core features for tracking knowledge growth. These results contribute to the broader understanding of how ITS systems can emulate human tutoring strategies to improve educational outcomes across various domains
Low temperature tolerance and thermal mortality of kudzu bug Megacopta cribraria (Plataspidae)
No full textThe kudzu bug, Megacopta cribraria (Hemiptera: Plataspidae), is an invasive species from Asia first discovered in the United States in 2009 in Georgia and in 2012 in Tennessee. The primary research goals of this project are to: (1) measure cold tolerance of the kudzu bug in a western Tennessee population and (2) assess mortality of the species at both the lower and upper lethal limits. Cold tolerance assays performed included critical thermal minimum (CTmin), chill coma recovery time (CCRT), and supercooling point (SCP). In conjunction with cold tolerance metrics, body water and body lipid content were assayed to better understand changes in body composition of the kudzu bug. Upper and lower lethal limits were determined to provide insights into the mortality of kudzu bugs at both extremes. The information collected in this project will enhance the understanding of cold tolerance mechanisms and seasonal shifts in cold tolerance for invasive insects
