Health Portal Functionality And The Use Of Patient-Centered Technology, Anita Joyce Simmons 2017 Walden University

Health Portal Functionality And The Use Of Patient-Centered Technology, Anita Joyce Simmons

Walden Dissertations and Doctoral Studies

Health portals are dedicated web pages for medical practices to provide patients access to their electronic health records. The problem identified in this quality improvement project was that the health portal in the urgent care setting had not been available to staff nor patients. To provide leadership with information related to opening the portal, the first purpose of the project was to assess staff and patients' perceived use, ease of use, attitude toward using, and intention to use the portal. The second purpose was to evaluate the portal education materials for the top 5 urgent care diagnoses: diabetes, hypertension, asthma ...

Preliminary Investigation Of Walking Motion Using A Combination Of Image And Signal Processing, Bradley Schneider, Tanvi Banerjee

Kno.e.sis Publications

We present the results of analyzing gait motion in first-person video taken from a commercially available wearable camera embedded in a pair of glasses. The video is analyzed with three different computer vision methods to extract motion vectors from different gait sequences from four individuals for comparison against a manually annotated ground truth dataset. Using a combination of signal processing and computer vision techniques, gait features are extracted to identify the walking pace of the individual wearing the camera as well as validated using the ground truth dataset. Our preliminary results indicate that the extraction of activity from the video ...

Museum 4.0 As The Future Of Steam In Museums, Mark Walhimer 2016 Tecnológico de Monterrey

Museum 4.0 As The Future Of Steam In Museums, Mark Walhimer

The STEAM Journal

Informal STEAM (Science, Technology, Engineering, Art and Math) activities (programs) and exhibits are common in science centers, children’s museums and natural history museums. As museums change to Museum 4.0 models (1), the STEAM exhibits and programs in museums also change. Museums 4.0 is the transformation of museums from a monolithic fixed location institution to a nimble community driven event driven organization. The Museum 4.0 becomes personalized to the visitor without fixed outcomes and without the physical restrictions of a single fixed location. As museums evolve to a Museum 4.0 model with visitor lead activities, STEAM ...

Gale-Shapley Matching In An Evolutionary Trade Network Game, Leigh Tesfatsion 2016 Iowa State University

Gale-Shapley Matching In An Evolutionary Trade Network Game, Leigh Tesfatsion

Leigh Tesfatsion

This study investigates the performance of Gale-Shapley matching in an evolutionary market context. Computational experimental findings are reported for an evolutionary match-and-play trade network game in which resource-constrained traders repeatedly choose and refuse trade partners in accordance with GaleShapley matching, participate in risky trades modeled two-person prisoner's dilemma games, and evolve their trade behavior over time. Particular attention is focused on correlations between ex ante market structure and the formation of trade networks, and between trade network formation and the types of trade behavior and social welfare outcomes that these trade networks support.


Hysteresis In An Evolutionary Labor Market With Adaptive Search, Leigh Tesfatsion 2016 Iowa State University

Hysteresis In An Evolutionary Labor Market With Adaptive Search, Leigh Tesfatsion

Leigh Tesfatsion

This study undertakes a systematic experimental investigation of hysteresis (path dependency) in an agent-based computational labor market framework. It is shown that capacity asymmetries between work suppliers and employers can result in two distinct hysteresis effects, network and-behavioral, when work suppliers and employers interact strategically and evolve their work site behaviors over time. These hysteresis effects result in persistent heterogeneity in earnings and employment histories across agents who have no observable structural differences. At a more global level, these hysteresis effects are shown to result in a one-to-many mapping between treatment factors and experimental outcomes. These hysteresis effects may help ...


An Evolutionary Trade Network Game With Preferential Partner Selection, Leigh Tesfatsion 2016 Iowa State University

An Evolutionary Trade Network Game With Preferential Partner Selection, Leigh Tesfatsion

Leigh Tesfatsion

An evolutionary trade network game (TNG) is proposed for studying the interplay between evolutionary game dynamics and preferential partner selection in various market contexts with distributed adaptive agents. The modular form of the TNG facilitates experimentation with alternative specifications for trade partner matching, trading, expectation updating, and trade strategy evolution. Experimental results obtained using a C-t-f implementation suggest that the conventional optimal properties used to evaluate agent matching mechanisms in static market contexts may be in an equate measures of optimal from an evolutionary perspective.

Teaching Complex Theoretical Multi-Step Problems In Ict Networking Through 3d Printing And Augmented Reality, Michael Cowling, James Birt 2016 Central Queensland University

Teaching Complex Theoretical Multi-Step Problems In Ict Networking Through 3d Printing And Augmented Reality, Michael Cowling, James Birt

James Birt

This paper presents a pilot study rationale and research methodology using a mixed media visualisation (3D printing and Augmented Reality simulation) learning intervention to help students in an ICT degree represent theoretical complex multi-step problems without a corresponding real world physical analog model. This is important because these concepts are difficult to visualise without a corresponding mental model. The proposed intervention uses an augmented reality application programmed with free commercially available tools, tested through an action research methodology, to evaluate the effectiveness of the mixed media visualisation techniques to teach ICT students networking. Specifically, 3D models of network equipment will ...


Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka 2016 Bond University

Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka

James Birt

Spatial visualization and interpretation are important skills for designers. However, these skills generally require significant experiential development over the course of years. Visualizations allow the human brain to convey complex spatial concepts in intuitive, navigable and manipulable forms improving learner outcomes and perceptions. But often these visualizations are studied as single modality solutions. Dual modality and multimedia presentation studies show positive improvements in learner outcomes but dual modality is often difficult to compare. This paper presents ongoing research in the use of comparative multimodal visualizations produced with emerging technology solutions in 3D Design classrooms. Presented are previous findings from multimedia ...


Computer Vision Based Object Detection And Tracking In Micro Aerial Vehicles, Richard F. Chapman, H. David Mathias 2016 Florida Southern College

Computer Vision Based Object Detection And Tracking In Micro Aerial Vehicles, Richard F. Chapman, H. David Mathias

Papers & Publications: Interdisciplinary Journal of Undergraduate Research

­­­­The ultimate goal of Computer Vision is to instruct a computer to understand and interpret visual signals and images in real time and to instruct a computer to react to the environment around them. In this work, we describe a system that allows a micro aerial vehicle (MAV), equipped with an onboard camera, to detect and track a moving target object. In an alternative implementation, the MAV instead searches the environment for the target object and flies to it. Due to the limited capability of the drone’s integrated processor, image processing is performed by a ground-based computer that also ...

Perceptions Of Planned Versus Unplanned Malfunctions: A Human-Robot Interaction Scenario, Theresa T. Kessler, Keith R. MacArthur, Manuel Trujillo-Silva, Thomas MacGillivray, Chris Ripa, Peter A. Hancock 2016 University of Central Florida

Perceptions Of Planned Versus Unplanned Malfunctions: A Human-Robot Interaction Scenario, Theresa T. Kessler, Keith R. Macarthur, Manuel Trujillo-Silva, Thomas Macgillivray, Chris Ripa, Peter A. Hancock

Keith Reid MacArthur

The present study investigated the effect of malfunctions on trust in a human-robot interaction scenario. Participants were exposed to either a planned or unplanned robot malfunction and then completed two different self-report trust measures. Resulting trust between planned and unplanned exposures was analyzed, showing that trust levels impacted by planned malfunctions did not significantly differ from those impacted by unplanned malfunctions. Therefore, it can be surmised that the methods used for the manipulation of the planned malfunctions were effective and are recommended for further study use.


Further Evidence Of The Contribution Of The Ear Canal To Directional Hearing: Design Of A Compensating Filter, Andrea Martelloni, Davide Andrea Mauro PhD, Antonio Mancuso 2016 Marshall University

Further Evidence Of The Contribution Of The Ear Canal To Directional Hearing: Design Of A Compensating Filter, Andrea Martelloni, Davide Andrea Mauro Phd, Antonio Mancuso

Davide Andrea Mauro

It has been proven, and it is well documented in literature, that the directional response in HRTFs comes largely from the effect of the pinnae. However, few studies have analysed the contribution given by the remaining part of the external ear, particularly the ear canal. This work investigates the directionally dependent response of the modelled ear canal of a dummy head, assuming that the behaviour of the external ear is sufficiently linear to be approximated by an LTI system. In order to extract the ear canal's transfer function, two critical microphone placements (at the eardrum and at the beginning ...
