Proceedings, MSVSCC 2015

The Virginia Modeling, Analysis and Simulation Center (VMASC) of Old Dominion University hosted the 2015 Modeling, Simulation, & Visualization Student capstone Conference on April 16th. The Capstone Conference features students in Modeling and Simulation, undergraduates and graduate degree programs, and fields from many colleges and/or universities. Students present their research to an audience of fellow students, faculty, judges, and other distinguished guests. For the students, these presentations afford them the opportunity to impart their innovative research to members of the M&S community from academic, industry, and government backgrounds. Also participating in the conference are faculty and judges who have volunteered their time to impart direct support to their students’ research, facilitate the various conference tracks, serve as judges for each of the tracks, and provide overall assistance to this conference. 2015 marks the ninth year of the VMASC Capstone Conference for Modeling, Simulation and Visualization. This year our conference attracted a number of fine student written papers and presentations, resulting in a total of 51 research works that were presented. This year’s conference had record attendance thanks to the support from the various different departments at Old Dominion University, other local Universities, and the United States Military Academy, at West Point. We greatly appreciated all of the work and energy that has gone into this year’s conference, it truly was a highly collaborative effort that has resulted in a very successful symposium for the M&S community and all of those involved. Below you will find a brief summary of the best papers and best presentations with some simple statistics of the overall conference contribution. Followed by that is a table of contents that breaks down by conference track category with a copy of each included body of work. Thank you again for your time and your contribution as this conference is designed to continuously evolve and adapt to better suit the authors and M&S supporters.

Emergence in the security of protocols for mobile ad-hoc networks

This thesis is concerned with the study of secure wireless routing protocols, which have been deployed for the purpose of exchanging information in an adhoc networking enviromnent. A discrete event simulator is developed, utilising an adaptive systems modelling approach and emergence that aims to assess networking protocols in the presence of adversarial behaviour. The model is used in conjunction with the characteristics that routing protocols have and also a number of cryptographic primitives that can be deployed in order to safeguard the information being exchanged. It is shown that both adversarial behaviour, as well as protocol descriptions can be described in a way that allows for them to be treated as input on the machine level. Within the system, the output generated selects the fittest protocol design capable of withstanding one or more particular type of attacks. As a result, a number of new and improved protocol specifications are presented and benchmarked against conventional metrics, such as throughput, latency and delivery criteria. From this process, an architecture for designing wireless routing protocols based on a number of security criteria is presented, whereupon the decision of using particular characteristics in a specification has been passed onto the machine level

Withholding Political Authority: Civil Society and People\u27s Power in Zimbabwe

The relationship of civil society to the state is rarely antagonistic and at most times supportive. The political regime and civil society are taken to be interdependent social structures that interact through hegemonic, supportive and socially constructed dimensions. Given this interdependency, when does civil society challenge authority or does its efforts rise to the level of a people\u27s power revolution? When does it act to dismantle the political regime or seek to reconstruct it? This project attempts to shed light on how civil society mobilizes a people\u27s power capable of challenging political authority through the story of its ongoing struggles to pursue social objectives in Zimbabwe in the 1990s. Since 1980, the Zimbabwe African National Union (Zanu) controlled the only post-colonial government Zimbabwe has known. Drawing from its revolutionary credentials it set out to finish the interrupted war for Zimbabwean Independence. This objective resonated with civil society less and less over time as groups began to see Zanu\u27s promises as hollow and its corruption and patronage systems as the primary obstacle in accomplishing their objectives. This development is explored through a grassroots empowerment movement, the Organisation of Rural Associations for Progress, the widespread protests in 1997 catalyzed by the Zimbabwean Congress of Trade Unions and the efforts to rebuild the constitutional order spearheaded by the National Constitutional Assembly. The story points to at least three civil society strategies to locate power within the people and counter political power: 1) constructing political alternatives within the existing regime, 2) mass withdrawal of support for the authority of the regime and 3) reconstruction of the social contract. Nevertheless, civil society did not succeed in dismantling the political regime, hampered by the continuing capacity of the state to exert hegemonic control, remove the pillars of civil society support and exploit polarized values within civil society. Despite the terrible destruction of social and economic fabric of the country by the political struggles of the 2000s, the ongoing development of democratic values and the diminishing importance of the interrupted revolution can provide a glimmer of hope for the future transformation of the country

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills
