Histogram Of Oriented Phase (Hop): A New Descriptor Based On Phase Congruency, Hussin Ragb, Vijayan K. Asari

Electrical and Computer Engineering Faculty Publications

In this paper we present a low level image descriptor called Histogram of Oriented Phase based on phase congruency concept and the Principal Component Analysis (PCA). Since the phase of the signal conveys more information regarding signal structure than the magnitude, the proposed descriptor can precisely identify and localize image features over the gradient based techniques, especially in the regions affected by illumination changes. The proposed features can be formed by extracting the phase congruency information for each pixel in the image with respect to its neighborhood. Histograms of the phase congruency values of the local regions in the image …

Suffering In Silence: Investigating The Role Of Fear In The Relationship Between Abusive Supervision And Defensive Silence, Christian Kiewitz, Simon Lloyd D. Restubog, Mindy K. Shoss, Patrick Raymund James M. Garcia, Robert L. Tang

Management and Marketing Faculty Publications

Drawing from an approach-avoidance perspective, we examine the relationships between subordinates’ perceptions of abusive supervision, fear, defensive silence, and ultimately abusive supervision at a later time point. We also account for the effects of subordinates’ assertiveness and individual perceptions of a climate of fear on these predicted mediated relationships. We test this moderated mediation model with data from three studies involving different sources collected across various measurement periods. Results corroborated our predictions by showing (a) a significant association between abusive supervision and subordinates’ fear, (b) second-stage moderation effects of subordinates’ assertiveness and their individual perceptions of a climate of fear …

Challenges And Supports During The Transition From High School To College For Students With Traumatic Brain Injuries, Michaela M. Kramer, Susan C. Davies

Counselor Education and Human Services Faculty Publications

Students who have sustained traumatic brain injuries (TBIs) may experience a number of consequences, all of which can impede the transition from high school to postsecondary educational settings. This study, which relied on interviews with students who had sustained TBIs and who had persistent problems related to their traumas, helped gain an understanding of their postsecondary transition experiences. Students’ parents were also interviewed to provide a point of comparison. The reports of these students—all of whom were enrolled in college at the time of the study—revealed significant challenges with attention and focus, fatigue, short-term memory, and social situations. Comments from …

Gecka3d: A 3d Game Engine For Commonsense Knowledge Acquisition, Erik Cambria, Tam Nguyen, Brian Cheng, Kenneth Kwok, Jose Sepulveda

Computer Science Faculty Publications

Commonsense knowledge representation and reasoning is key for tasks such as artificial intelligence and natural language understanding. Since commonsense consists of information that humans take for granted, gathering it is an extremely difficult task. In this paper, we introduce a novel 3D game engine for commonsense knowledge acquisition (GECKA3D) which aims to collect commonsense from game designers through the development of serious games. GECKA3D integrates the potential of serious games and games with a purpose. This provides a platform for the acquisition of reusable and multi-purpose knowledge and also enables the development of games that can provide entertainment value and …

A Study Of Android Malware Detection Techniques And Machine Learning, Balaji Baskaran, Anca Ralescu

MAICS: The Modern Artificial Intelligence and Cognitive Science Conference

Android OS is one of the widely used mobile Operating Systems. The number of malicious applications and adwares are increasing constantly on par with the number of mobile devices. A great number of commercial signature based tools are available on the market which prevent to an extent the penetration and distribution of malicious applications. Numerous researches have been conducted which claims that traditional signature based detection system work well up to certain level and malware authors use numerous techniques to evade these tools. So given this state of affairs, there is an increasing need for an alternative, really tough malware …

Situations And Evidence For Identity Using Dempster-Shafer Theory, William Nick, Yenny Dominguez, Albert Esterline

MAICS: The Modern Artificial Intelligence and Cognitive Science Conference

We present a computational framework for identity based on Barwise and Devlin’s situation theory. We present an example with constellations of situations identifying an individual to create what we call id-situations, where id-actions are performed, along with supporting situations. We use Semantic Web standards to represent and reason about the situations in our example. We show how to represent the strength of the evidence, within the situations, as a measure of the support for judgments reached in the id-situation. To measure evidence of an identity from the supporting situations, we use the Dempster-Shafer theory of evidence. We enhance Dempster- Shafer …

A Tool For Staging Mixed-Initiative Dialogs, Joshua W. Buck, Saverio Perugini

MAICS: The Modern Artificial Intelligence and Cognitive Science Conference

We discuss and demonstrate a tool for prototyping dialog-based systems that, given a high-level specification of a human-computer dialog, stages the dialog for interactive use. The tool enables a dialog designer to evaluate a variety of dialogs without having to program each individual dialog, and serves as a proof-of-concept for our approach to mixed-initiative dialog modeling and implementation from a programming language-based perspective.

Keynote Talk 2: Social And Perceptual Fidelity Of Avatars And Autonomous Agents In Virtual Reality, Benjamin Kunz

MAICS: The Modern Artificial Intelligence and Cognitive Science Conference

Advances in display, computing and sensor technologies have led to a revival of interest and excitement surrounding immersive virtual reality. Here, on the cusp of the arrival of practical and affordable virtual reality technology, are open questions regarding the factors that contribute to compelling and immersive virtual worlds.

In order for virtual reality to be useful as a tool for use in training, education, communication, research, content-creation and entertainment, we must understand the degree to which the perception of the virtual environment and virtual characters resembles perception of the real world.

Relatedly, virtual reality's utility in these contexts demands evidence …

The Webid Protocol Enhanced With Group Access, Biometrics, And Access Policies, Cory Sabol, William Nick, Maya Earl, Joseph Shelton, Albert Esterline

MAICS: The Modern Artificial Intelligence and Cognitive Science Conference

The WebID protocol solves the challenge of remembering usernames and passwords. We enhance this protocol in three ways. First, we give it the ability to manage groups of agents and control their access to resources on the Web. Second, we add support for biometric access control to enhance security. Finally, we add support for OWL-based policies that may be federated and result in flexible access control.

Regeneration Research, University Of Dayton

News Releases

Imagine losing an eye, an arm or even your spinal cord. When we are wounded, our bodies, and those of other mammals, generally respond by sealing the wound with scar tissue. The newt, however, can repeatedly regenerate lost tissues, even as an adult. Recent research led by University of Dayton Biology Professor Panagiotis A. Tsonis and Chikafumi Chiba at the University of Tsukuba in Japan, published in the current volume of the prestigious journal Nature Communications, has shed some light on the newt’s exceptional regenerative ability and may provide further insight into regeneration in other species, including mammals.

"Designerly" Ways Of Reading: Insights From Reader Response In Drama For Enriching The "A" In Language Arts, Treavor Bogard

Teacher Education Faculty Publications

In this interpretive case study of reader response in drama, a drama troupe is the context for illuminating how young actors read in "designerly" ways; that is, how their reading processes facilitated constructive, solution-focused thinking in their development of characterizations. By examining the nature of reader response in the drama troupe, I hope to help educators understand how design thinking occurred as an aesthetic reading practice and consider ways in which design thinking can be cultivated in the language arts classroom. I argue that design thinking inspires the young to engage the imagination, practice teamwork, and take risks as they …

Diffractive Propagation And Recovery Of Modulated (Including Chaotic) Electromagnetic Waves Through Uniform Atmosphere And Modified Von Karman Phase Turbulence, Monish Ranjan Chatterjee, Fathi H.A. Mohamed

Electrical and Computer Engineering Faculty Publications

In a parallel approach to recently-used transfer function formalism, a study involving diffraction of modulated electromagnetic (EM) waves through uniform and phase-turbulent atmospheres is reported in this paper. Specifically, the input wave is treated as a modulated optical carrier, represented by use of a sinusoidal phasor with a slowly timevarying envelope. Using phasors and (spatial) Fourier transforms, the complex phasor wave is transmitted across a uniform or turbulent medium using the Kirchhoff-Fresnel integral and the random phase screen.

Some preliminary results are presented comparing non-chaotic and chaotic information transmission through turbulence, outlining possible improvement in performance utilizing the robust features …

Differential Tilt Variance Effects Of Turbulence In Imagery: Comparing Simulation With Theory, Daniel A. Lemaster, Russell C. Hardie, Szymon Gladysz, Matthew D. Howard, Michael Armand Rucci, Matthew E. Trippel, Jonathan D. Power, Barry K. Karch

Electrical and Computer Engineering Faculty Publications

Differential tilt variance is a useful metric for interpreting the distorting effects of turbulence in incoherent imaging systems. In this paper, we compare the theoretical model of differential tilt variance to simulations. Simulation is based on a Monte Carlo wave optics approach with split step propagation. Results show that the simulation closely matches theory. The results also show that care must be taken when selecting a method to estimate tilts.

Faculty Views Of “Nontraditional” Students: Aligning Perspectives For Student Success, Desiree D. Zerquera, Mary Ziskin, Vasti Torres

Educational Leadership Faculty Publications

Faculty serve as a primary point of contact for students in college, playing vital roles in students’ retention and attainment. The perceptions and beliefs held by these institutional actors are important for understanding the context that shapes students’ experiences while they are in college and potentially, long after they leave. The purpose of this work is to examine faculty members’ perceptions of nontraditional student experiences. Findings highlight faculty members’ awareness of students’ multiple roles and obligations; perceptions of student academic success, including barriers to succeeding; and the ways faculty connect with students and the types of connections they forge. The …

Looking Anew At The Rothko Chapel: The Future Of Interfaith Space On The Catholic Campus, Krista Bondi

Honors Theses

The University of Dayton is among many Catholic institutions that are experiencing the need for multi-faith accommodation as its student body becomes more diverse in the 21st century. While the majority of the University’s population is Catholic, there are growing numbers of Muslim, Jewish, and Protestant students as well as others of undeclared faiths or of no faith traditions who must interact on campus. In view of the history of Catholic higher education and the current practice and philosophy of interfaith dialogue, how should the University of Dayton approach this new multi-cultural reality in terms of dedicating space and designing …

Large-Area Object Search And Recovery Using Sector-Based Aerial Acousto-Optic Scanning And Reflection Sensing, Monish Ranjan Chatterjee, Salaheddeen G. Bugoffa

Electrical and Computer Engineering Faculty Publications

A sector-based angular scanning system intended to identify and spatially locate relatively small objects scattered over a large terrain is described in this paper. The system is modeled as a planar surface on the horizontal (XY) plane, with an acousto-optic Bragg cell on board an unmanned aerial vehicle (UAV) operating in the XZ plane.

The Bragg cell is excited by a chirped RF signal with a designed frequency ramp. As the scanning beam reflects off the horizontal surface, a detector placed strategically at a suitable altitude (in the analysis shown to be on board the UAV itself) picks up the …

Negotiating A Culture Of Encounter And Disruptive Discourse In Catholic Higher Education, Laura Leming

Sociology, Anthropology, and Social Work Faculty Publications

Any brief attention to global, national, and local news underlines the urgency for education that leads to knowledge about and action for the common good. Catholic institutions of higher learning have a dual history of encouraging students to speak and act on behalf of the common good while also pursuing the good life. As those who can readily access a Catholic education have increasingly come from the upper middle class, how are we introducing our students into the culture of encounter that Pope Francis called the U.S. Bishops to promote in September 2015? This essay explores ideas and examples related …

“Instafamous” Women And The Question Of Empowerment: Feminist Reading Of Popular Constructions Of Female Bodies On Instagram, Sarah Spech

Honors Theses

Instagram has skyrocketed in popularity over the last few years, catapulting some of its users into a new type of fame--"Instafame." Female users who achieve "Instafame" do so in large measure by carefully constructing an identity that articulates a popular ideal of the female body. Many commentators see this presentation of self as a new means of empowerment. But others argue that these "Instafamous" women are pressured to objectify themselves in order to accumulate thousands of “likes” to create and sustain their celebrity status. In this presentation, I analyze the images on some popular fitness Instagram accounts using the feminist …
