An Introduction To Declarative Programming In Clips And Prolog, Jack L. Watkin, Adam C. Volk, Saverio Perugini Aug 2019

An Introduction To Declarative Programming In Clips And Prolog, Jack L. Watkin, Adam C. Volk, Saverio Perugini

Saverio Perugini

We provide a brief introduction to CLIPS—a declarative/logic programming language for implementing expert systems—and PROLOG—a declarative/logic programming language based on first-order, predicate calculus. Unlike imperative languages in which the programmer specifies how to compute a solution to a problem, in a declarative language, the programmer specifies what they what to find, and the system uses a search strategy built into the language. We also briefly discuss applications of CLIPS and PROLOG.

Cse: U: Mixed-Initiative Personal Assistant Agents, Joshua W. Buck, Saverio Perugini, Tam Nguyen

Saverio Perugini

Specification and implementation of flexible human-computer dialogs is challenging because of the complexity involved in rendering the dialog responsive to a vast number of varied paths through which users might desire to complete the dialog. To address this problem, we developed a toolkit for modeling and implementing task-based, mixed-initiative dialogs based on metaphors from lambda calculus. Our toolkit can automatically operationalize a dialog that involves multiple prompts and/or sub-dialogs, given a high-level dialog specification of it. The use of natural language with the resulting dialogs makes the flexibility in communicating user utterances commensurate with that in dialog completion paths—an aspect …

Natural Language, Mixed-Initiative Personal Assistant Agents, Joshua W. Buck, Saverio Perugini, Tam W. Nguyen Oct 2018

Natural Language, Mixed-Initiative Personal Assistant Agents, Joshua W. Buck, Saverio Perugini, Tam W. Nguyen

Saverio Perugini

The increasing popularity and use of personal voice assistant technologies, such as Siri and Google Now, is driving and expanding progress toward the long-term and lofty goal of using artificial intelligence to build human-computer dialog systems capable of understanding natural language. While dialog-based systems such as Siri support utterances communicated through natural language, they are limited in the flexibility they afford to the user in interacting with the system and, thus, support primarily action-requesting and information-seeking tasks. Mixed-initiative interaction, on the other hand, is a flexible interaction technique where the user and the system act as equal participants in an …

An Application Of The Actor Model Of Concurrency In Python: A Euclidean Rhythm Music Sequencer, Daniel P. Prince, Saverio Perugini

Saverio Perugini

We present a real-time sequencer, implementing the Euclidean rhythm algorithm, for creative generation of drum sequences by musicians or producers. We use the Actor model of concurrency to simplify the communication required for interactivity and musical timing, and generator comprehensions and higher-order functions to simplify the implementation of the Euclidean rhythm algorithm. The resulting application sends Musical Instrument Digital Interface (MIDI) data interactively to another application for sound generation.

Haptic Alternatives For Mobile Device Authentication By Older Technology Users, David M. Cook, Kulwinder Kaur

Dr. David M Cook

Turing tests are used to secure the human interaction on the Internet. Tests such as CAPTCHA are based on visual or auditory recognition of symbols and are difficult to distinguish by elderly people. A study examining the consistency of a tactile feedback-based Turing test identified an alternative to mainstream tests. This approach examines the vibration-based sensitivity which is detectable through skin surfaces when used to touch the screen of a mobile device. The study concentrated on a range of rough, smooth, sticky and coarse textures as possible differentiators for swipe-based tactile authentication using mobile devices. This study examined the vibration-based …

This study was conducted to better understand the performance of the XCOR Lynx vehicle. Because the Lynx development was halted, the best knowledge of vehicle dynamics can only be found through simulator flights. X-Plane 10 was chosen for its robust applications and accurate portrayal of dynamics on a vehicle in flight. The Suborbital Space Flight Simulator (SSFS) and Mission Control Center (MCC) were brought to the Applied Aviation Sciences department in fall 2015 at Embry-Riddle Aeronautical University, Daytona Beach campus. This academic and research tool is a department asset capable of providing multiple fields of data about suborbital simulated flights. …


Evaluating The Effectiveness Of Flipped Classrooms For Teaching Cs1, Ashish Amresh, Adam R. Carberry, John Femiani Apr 2018

Evaluating The Effectiveness Of Flipped Classrooms For Teaching Cs1, Ashish Amresh, Adam R. Carberry, John Femiani

Ashish Amresh

An alternative to the traditional classroom structure that has seen increased use in higher education is the flipped classroom. Flipping the classroom switches when assignments (e.g. homework) and knowledge transfer (e.g. lecture) occur. Flipped classrooms are getting popular in secondary and postsecondary teaching institutions as evidenced by the marked increase in the study, use, and application of the flipped pedagogy as it applies to learning and retention. The majority of the courses that have undergone this change use applied learning strategies and include a significant “learning-by-doing” component. The research in this area is skewed towards such courses and in general …

Interactive Cause And Effect Comic-Book Storytelling For Improving Nutrition Outcomes In Children, Ashish Amresh, Madhumita Sinha, Rebecca Birr, Rahul Salla

Ashish Amresh

Obesity among children and adolescents is increasingly becoming a major public health problem. Poverty and lower socio-economic status as well as lack of parental awareness regarding a balanced diet and adequate exercise all contribute towards childhood obesity. Unfortunately minority children have been especially vulnerable, among them inner-city Latino children continue to have the highest incidence rates of overweight and obesity; hence targeted intervention for this population group is of paramount importance. Access and affordability of smartphones and mobile internet devices provide an opportunity to create nutrition education interventions that can significantly impact and change attitude and knowledge regarding healthy diet …


Developing A Bilingual, Computer-Tailored, Hpv Vaccination Promotion Intervention Targeting Latino Parents, Angela Chia-Chen Chen, Ashish Amresh Apr 2018

Developing A Bilingual, Computer-Tailored, Hpv Vaccination Promotion Intervention Targeting Latino Parents, Angela Chia-Chen Chen, Ashish Amresh

Ashish Amresh

In this paper we present an innovative, computer-tailored application aimed at increasing Latino parents' intention to vaccinate their adolescent children against Human Papilloma Virus (HPV). HPV infection is the most common sexually transmitted infection in the United States. Latinas have the highest age-adjusted incidence rate for HPV-associated cervical cancer compared with their counterparts in other racial/ethnic groups. HPV vaccines offer hope against HPV-associated diseases. Because parental consent is required for children under age 18 to receive t h e HPV vaccination in most U. S. states, parents' attitudes and intention to have their children vaccinated are keys for promoting HPV …

Our efforts open the possibility for other learning games to be reworked into new genres, increasing novelty and player engagement. Expanding the range of genres also allows for learning games to reach a wider audience. The goal of the WT is to provide a natural method for …


Towards A Context Agnostic Platform For Design And Assessment Of Educational Games, Tyler Baron, Corey Heath, Ashish Amresh Apr 2018

Towards A Context Agnostic Platform For Design And Assessment Of Educational Games, Tyler Baron, Corey Heath, Ashish Amresh

Ashish Amresh

The majority of the games designed for improving, acquiring or transferring knowledge rely heavily on building game mechanics that are grounded deeply in the content or subject matter being taught. There is a growing need for educational practitioners and pedagogical experts to have the ability to easily map learning outcomes by choosing from a pallet of functioning game mechanics without having the need to redesign them from scratch. In this paper, we present the current state of the art in context agnostic design and assessment of educational games, and propose three strategies that educators can take advantage of during the …

The Open World Microorganism, Stephen Thompson

Stephen Thompson

Video games have been creating sprawling open world experiences for years, but as of yet none have ventured to create an authentic inner cell experience, using our knowledge of cells to recreate digitally what it would be like to shrink smaller than one and step inside. The benefits this application could yield are manifold, so this paper references the necessary ingredients and draws up the blueprints for the first three-dimensional, fully explorable, customizable, and interactive microorganism: an invention which could usher in a new age of biological literacy using technology already employed by many video games. The first part of …


Revisiting The Futamura Projections: A Diagrammatic Approach, Brandon Williams, Saverio Perugini Feb 2018

Revisiting The Futamura Projections: A Diagrammatic Approach, Brandon Williams, Saverio Perugini

Saverio Perugini

The advent of language implementation tools such as PyPy and Truffle/Graal have reinvigorated and broadened interest in topics related to automatic compiler generation and optimization. Given this broader interest, we revisit the Futamura Projections using a novel diagram scheme. Through these diagrams we emphasize the recurring patterns in the Futamura Projections while addressing their complexity and abstract nature. We anticipate that this approach will improve the accessibility of the Futamura Projections and help foster analysis of those new tools through the lens of partial evaluation.


Building Capable, Energy-Efficient, Flexible Visualization And Sensing Clusters From Commodity Tablets, Thomas Delgado Dias, Xian Yan, Konstantin Läufer, George K. Thiruvathukal Oct 2017

Building Capable, Energy-Efficient, Flexible Visualization And Sensing Clusters From Commodity Tablets, Thomas Delgado Dias, Xian Yan, Konstantin Läufer, George K. Thiruvathukal

Konstantin Läufer

We explore the application of clusters of commodity tablet devices to problems spanning a “trilogy” of concerns: visualization, sensing, and computation. We conjecture that such clusters provide a low-cost, energy-efficient, flexible, and ultimately effective platform to tackle a wide range of problems within this trilogy. This is a work in progress, and we now elaborate our position and give a preliminary status report. A wide range of Android tablet devices are available in terms of price and capabilities. “You get what you pay for” w.r.t. display resolution, sensors, and chipset---corresponding to the trilogy. $200 gets one a 1280x800-pixel touch display, …


Micro Dh: Digital Humanities At The Small Scale, Roopika Risam, Susan Edwards Aug 2017

Micro Dh: Digital Humanities At The Small Scale, Roopika Risam, Susan Edwards

Roopika Risam

Digital humanities practices are often understood in terms of significant scale: big data, large data sets, digital humanities centers (Terras et al. 2016; Kowalczyk et al. 2014; Borgman 2009; Kretzschmar 2009). This emphasis leads to the perception that projects cannot be completed without substantial access to financial resources, data, and labor (Prescott 2016; Hockey 2016; Evans and Rees 2012). While this can be the case, such presumptions serve as a deterrent to the development of an inclusive digital humanities community with representation across academic hierarchies (student, librarian, faculty), types of institutions (public, private, regional), and geographies (Global North, Global South). …

A Pilot Study Of Computerized, Tailored Intervention To Promote Hpv Vaccination In Mexican-Heritage Adolescents, Angaela Chia-Chen Chen, Michael Todd, Ashish Amresh, Usha Menon, Laura Szalacha

Ashish Amresh

This study examined feasibility, acceptability, and preliminary effect of a computer-tailored intervention aimed at promoting HPV vaccination in Mexican-heritage adolescents aged 11-17. Among 46 Mexican-heritage parents who had one or more eligible children who had not received HPV vaccines, 91% (n = 42) completed the intervention and assessments via tablets in a vaccine clinic. Mean knowledge scores increased significantly from pre- to post-intervention. After the intervention, 95% (n = 40) of parents intended to get their children vaccinated; 50% (n = 21) of them consented to vaccination immediately, resulting in 24 adolescents being vaccinated at that time. All parents reported …


Mhealth Games As Rewards: Incentive Or Distraction?, Kevin Gary, Ryan Stoll, Pooja Rallabhandi, Mandar Patwardhan, Derek Hamel, Ashish Amresh, Armando Pina, Kevin Cleary, Zenaide Quezado Jun 2017

Mhealth Games As Rewards: Incentive Or Distraction?, Kevin Gary, Ryan Stoll, Pooja Rallabhandi, Mandar Patwardhan, Derek Hamel, Ashish Amresh, Armando Pina, Kevin Cleary, Zenaide Quezado

Ashish Amresh

Games may be employed for delivery of a clinical protocol, or as an incentive for protocol tasks. We focus on serious games in mHealth apps for pediatric patients with a chronic disease as an incentive for behavior modification. A patient is rewarded with enhanced gameplay in proportion to her/his compliance with a clinical protocol. The game-as-reward prevents fatigue and sustains patient engagement as the mHealth apps are used on a frequent basis when the affliction is a chronic disease. However, our experience shows a fine line between games that encourage engagement and ones that distract patients from protocol tasks.
