Health Portal Functionality And The Use Of Patient-Centered Technology, 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 ...

Research Collection School Of Information Systems
The Orienteering Problem (OP) has received a lot of attention in the past few decades. The OP is a routing problem in which the goal is to determine a subset of nodes to visit, and in which order, so that the total collected score is maximized and a given time budget is not exceeded. A number of typical variants has been studied, such as the Team OP, the (Team) OP with Time Windows and the Time Dependent OP. Recently, a number of new variants of the OP was introduced, such as the Stochastic OP, the Generalized OP, the Arc OP ...

Preliminary Investigation Of Walking Motion Using A Combination Of Image And Signal Processing, 2016 Wright State University - Main Campus
Preliminary Investigation Of Walking Motion Using A Combination Of Image And Signal Processing, Bradley Schneider, Tanvi Banerjee
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, 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 ...
Market Power And Efficiency In A Computational Electricity Market With Discriminatory Double-Auction Pricing, 2016 Iowa State University
Market Power And Efficiency In A Computational Electricity Market With Discriminatory Double-Auction Pricing, James Nicolaisen, Valentin Petrov, Leigh Tesfatsion
This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating In the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminator}- midpoint pricing. Buyers and sellers use a modified Roth-Erev individual reinforcement learning algorithm to determine their price and quantity offers in each auction round. It is shown that high market efficiency is generally attained, and that market microstructure is strongly predictive for the relative market power of buyers and sellers independently of the values set for the reinforcement ...

Gale-Shapley Matching In An Evolutionary Trade Network Game, 2016 Iowa State University
Gale-Shapley Matching In An Evolutionary Trade Network Game, 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, 2016 Iowa State University
Hysteresis In An Evolutionary Labor Market With Adaptive Search, 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, 2016 Iowa State University
An Evolutionary Trade Network Game With Preferential Partner Selection, 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, 2016 Central Queensland University
Teaching Complex Theoretical Multi-Step Problems In Ict Networking Through 3d Printing And Augmented Reality, Michael Cowling, 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, 2016 Bond University
Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka
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, 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 ...

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 ...
