Makerspaces can support educational experiences in prototyping for young learners, while physical computing platforms enable high levels of creativity and expression. However, each of these have high barriers of entry, especially for youth without prior experience. Commercial microcontrollers have become a popular tool to use when designing both…

This thesis explores the use of Augmented Reality (AR) in two challenging scenarios -- autism therapy, and network-constrained, remote collaboration. In the first half of this thesis, we highlight the design and implementation of CustomAR and Augmented Playgrounds -- two applications that leverage the visualization and contextual abilities of AR…

Escape room games have emerged in the educational landscape over the last decade and are growing in popularity. Studies show that participants enjoy educational escape room games, however the data to demonstrate learning acquisition and behavior change is limited. This study addressed the research question: How effective are escape room games as a…

The primary purpose of this study was to determine if WebVR enhances the knowledge retention regarding mechanical components of high-risk moving machinery, specifically elevators. There were 23 participants divided into a treatment group and comparison group. The treatment group used WebVR to take a virtual elevator machine room tour while the…

The Border Gateway Protocol (BGP) is critical to the global internet infrastructure. Unfortunately BGP routing was designed with limited regard for security. As a result, IP route hijacking has been observed for more than 16 years. Well known incidents include a 2008 hijack of YouTube, loss of connectivity for Australia in February 2012, and an…

This thesis describes the development and deployment of a cyberinfrastructure for distributed high-throughput computations of materials properties at high pressures and/or temperatures--the Virtual Laboratory for Earth and Planetary Materials--VLab. VLab was developed to leverage the aggregated computational power of grid systems to solve…

In a Service Oriented Architecture (SOA), the hierarchical complexity of Web Services (WS) and their interactions with the underlying Application Server (AS) create new challenges in providing a realistic estimate of WS performance and reliability. The current approaches often treat the entire WS environment as a black-box. Thus, the sensitivity…

Cross-selling and product bundling are prevalent strategies in the retail sector. Instead of static bundling offers, i.e. giving the same offer to everyone, personalized dynamic cross-selling generates targeted bundle offers and can help maximize revenues and profits. In resolving the two basic problems of dynamic cross-selling, which involves…

Fieldbus networks are all-digital, two-way, multi-drop communication systems that are used to connect field devices such as sensors and actuators, and controllers. These fieldbus network systems are also called networked control systems (NCS). Although, there are different varieties of fieldbus networks such as Foundation Field Bus, DeviceNet, and…

This research details a methodology designed for creating content in support of various phishing prevention tasks including live exercises and detection algorithm research. Our system uses probabilistic context-free grammars (PCFG) and variable interpolation as part of a multi-pass method to create diverse and consistent phishing email content on…

This study investigated how students in two states, one with and one without a state-wide one-to-one laptop program, performed on measures of online research and learning in science. The study replicated and extended the findings of a recent study using more current and more extensive data. In general, this study adds to the body of research…

First responders are continuously moving at an incident site and this movement requires them to access Service-Oriented Architecture services, such as a Web Map Service, via mobile wireless networks. First responders from inside a building often have problems in communicating to devices outside that building due to propagation obstacles. Dynamic…

The inclusion of three-dimensional (3D) virtual tools has created a need to communicate the engagement of 3D tools and specify learning gains that educators and the institutions, which are funding 3D tools, can expect. A review of literature demonstrates that specific models and theories for 3D Virtual Reality (VR) learning do not exist "per…

The purpose of this study was to discover which andragogical characteristics and expectations of adult learners manifested themselves in the three-dimensional, multi-user virtual environment known as Second Life. This digital ethnographic study focused specifically on adult students within the University of Hawai'i Second Life group and their…

"Second Life," a 3D online immersive virtual environment, emerged in 2003 and was predicted to become the predominant online course delivery platform by 2013. Educational institutions initially rushed to create a presence in the "Second Life;" however, after 2009 those same institutions were disappointed by their experiences…
