Cplop - Cal Poly's Library Of Pyroprints, Kevin Webb
Computer Engineering
California Polytechnic Library of Pyroprints, CPLOP, is a web driven data-base application that stores data from the biology’s departments E. coli Pyrosequencing project. Some of this data was stored in Excel datasheets, while data from the pyrosequencing machines was stored as just a list of random .xml files. There was no useful way to organize and store the massive amounts of data from multiple file sources in one location, nor to perform the complicated searches and comparisons that the project requires. CPLOP’s primary goal is to store such data in three organized tables that relate to one another. It was …
Determining The Validity Of The Nintendo Wii Balance Board As An Assessment Tool For Balance, Sabrina Mae Deans

UNLV Theses, Dissertations, Professional Papers, and Capstones
Context. Application of the Nintendo Wii-fit balance board and its games have been used in Physical Therapy clinics, showing success in individuals with neurological disorders, and has been recommended as a minimum baseline assessment of a symptoms checklist and standardized cognitive and balance assessments for concussion management by the NCAA. However, it still faces challenges of being considered a reliable and consistent tool for producing normative data in the allied healthcare. Because there is little to no evidence for the Wii-fit balance board as a valid balance assessment tool for clinical and/or research usage, the significance of this study is …

Semantic Geotagging: A Location-Based Hypermedia Approach To Creating Situational Awareness, Ray Bareiss, Martin Griss, Steven Rosenberg, Yu Zhang
Ray Bareiss
As emergency first responders and commanders increasingly use mobile phones, tablets, and social media to communicate, coordinate, and manage information during disasters, we see a need and opportunity to provide a mobile device-appropriate semantic layer to a geographically-based common operating picture. The challenge is to provide a simple, usable structure for a rapidly growing body of information to simplify the development of situational awareness in an unfolding disaster. We use a hyperlinked structure based on the ASK model to organize information in a readily accessible form. In this paper we describe our initial design and experience with an Android-based prototype, …

Apple Ipad Cart, Gregory Keith Bartley Jr., Brandon J. Horvath
Gregory Keith Bartley Jr.
Utilizing a Pelican Accessories Case, I was able to construct a power efficient, mobile iPad charging station cart capable of safely charging and transporting up to 10 iPads and 10 iPad Keyboards with additional compartments to accommodate any additional cords and/or devices. The introduction of WiFi Sync in Apple's iOS 5 Update allowed me to more efficiently compartmentalize any cords from being exposed. Compared to commercially-available iPad Sync and Cart Charging Systems which charge $1000+, this unit cost me around $100. It also uses far less power, due to no longer needing a powered USB hub network in order to …
An Exploration Of Knowledge And Skills Transfer From A Formal Software Engineering Curriculum To A Capstone Practicum Project, Ray Bareiss, Ed Katz
An Exploration Of Knowledge And Skills Transfer From A Formal Software Engineering Curriculum To A Capstone Practicum Project, Ray Bareiss, Ed Katz
Ray Bareiss
Students at Carnegie Mellon Silicon Valley complete a team-based practicum project for an industrial sponsor as the capstone of their master’s education in software engineering. Over time, the faculty member who typically serves as advisor for such projects has been disturbed by the failure of several student teams to transfer some relevant knowledge and skills from the formal curriculum to the relatively unstructured practicum project environment. We conducted a survey of all 2010 software engineering students to ascertain the most significant selfreported shortcomings. This paper presents the survey data and then discusses the results in terms of a theory of …
Reconfigurable Systems: A Potential Solution To The Von Neumann Bottleneck, Damian L. Miller
Reconfigurable Systems: A Potential Solution To The Von Neumann Bottleneck, Damian L. Miller
Senior Honors Theses
The difficulty of overcoming the disparity between processor speeds and data access speeds, a condition known as the von Neumann bottleneck, has been a source of consternation for computer hardware developers for many years. Although a number of temporary solutions have been proposed and implemented in modern machines, these solutions have only managed to treat the major symptoms, rather than solve the root problem. As the number of transistors on a chip roughly doubles every two years, the von Neumann bottleneck has continued to tighten in spite of these solutions, prompting some computer hardware professionals to advocate a paradigm shift …

Imirok: Real-Time Imitative Robotic Arm Control For Home Robot Applications, Heng-Tze Cheng, Zheng Sun, Pei Zhang
Zheng Sun
Training home robots to behave like human can help people with their daily chores and repetitive tasks. In this paper, we present Imirok, a system to remotely control robotic arms by user motion using low-cost, off-the-shelf mobile devices and webcam. The motion tracking algorithm detects user motion in real-time, without classifier training or predefined action set. Experimental results show that the system achieves 90% precision and recall rate on motion detection with blank background, and is robust under the change of cluttered background and user-to-camera distance.
Leveraging Mobile Context For Effective Collaboration And Task Management In Disaster Response, Faisal Luqman, Martin L. Griss
Leveraging Mobile Context For Effective Collaboration And Task Management In Disaster Response, Faisal Luqman, Martin L. Griss
Martin L Griss
Collaboration and task management is challenging in distributed, dynamically-formed teams, typical in large scale disaster response scenarios. Ineffective collaboration may result in poor performance and possible loss of life. In this paper, we present Overseer, an agent-based system that exploits context information from mobile devices to facilitate collaboration and task allocation. We describe our system architecture and show how mobile context can be used to create dynamic role-based assignments to support collaboration and effective task management.

Sharing sensitive context information among multiple distributed components in mobile environments introduces major security concerns. The distributed sensing, processing and actuating components of these applications can be compromised and modified or impersonated to extract private and confidential information or to inject false information. In this paper we present the Anubis protocol for remote code attestation and access control of distributed components using remote execution of trusted code. Our Anubis protocol leverages previous work in the fields of wireless sensor networks and secure web browsing. Anubis allows new components to be introduced to the environment without updating existing components. Our implementation …

A previous study shows that busy professionals receive in excess of 50 emails per day of which approximately 23% require immediate attention, 13% require attention later and 64% are unimportant and typically ignored. The flood of emails impact mobile users even more heavily. Flooded inboxes cause busy professionals to spend considerable amounts of time searching for important messages, and there has been much research into automating the process using email content for classification; but we find email priority depends also on user context. In this paper we describe the Personal Messaging Assistant (PMA), an advanced rule-based email management system which …

"Symbolic location of a user, like a store name in a mall, is essential for context-based mobile advertising. Existing fingerprint- based localization using only a single phone is susceptible to noise, and has a major limitation in that the phone has to be held in the hand at all times. In this paper, we present SensOrchestra, a col- laborative sensing framework for symbolic location recognition that groups nearby phones to recognize ambient sounds and images of a location collaboratively. We investigated audio and image features, and designed a classifier fusion model to integrate estimates from diff erent phones. We also …

Omnisense: A Collaborative Sensing Framework For User Context Recognition Using Mobile Phones, Heng-Tze Cheng, Senaka Buthpitiya, Feng-Tso Sun, Martin L. Griss
Martin L Griss
Context information, including a user’s locations and activities, is indispensable for context-aware applications such as targeted advertising and disaster response. Inferring user context from sensor data is intrinsically challenging due to the semantic gap between low-level signals and high-level human activities. When implemented on mobile phones, more challenges on resource limitations are present. While most existing work focuses on context recognition using a single mobile phone, collaboration among multiple phones has received little attention, and the recognition accuracy is susceptible to phone position and ambient changes. Simply putting a phone in one’s pocket can render the microphone muffled and the …

Room-Level Wi-Fi Location Tracking, Joshua Correa, Ed Katz, Patricia Collins, Martin Griss
Martin L Griss
Context-aware applications for indoor intelligent environments require an appropriately accurate and stable interior positioning system to adapt services to the location of a mobile user or mobile device in a building. Different technologies provide a varying mix of resolution, accuracy, stability and challenges. In this paper we report on our experience using an existing Wi-Fi infrastructure without specialized hardware added to support location tracking. There are several approaches to track the location of Wi-Fi enabled devices within a building such as signal propagation models and signature matching. We found signature matching most effective in our environment. Signature matching is accomplished …
Leveraging Multi-Radio Communication For Mobile Wireless Sensor Networks, Jeremy J. Gummeson
Leveraging Multi-Radio Communication For Mobile Wireless Sensor Networks, Jeremy J. Gummeson
Masters Theses 1911 - February 2014
An important challenge in mobile sensor networks is to enable energy-efficient communication over a diversity of distances while being robust to wireless effects caused by node mobility. In this thesis, we argue that the pairing of two complementary radios with heterogeneous range characteristics enables greater range and interference diversity at lower energy cost than a single radio. We make three contributions towards the design of such multi-radio mobile sensor systems. First, we present the design of a novel reinforcement learning-based link layer algorithm that continually learns channel characteristics and dynamically decides when to switch between radios. Second, we describe a …

Contextualized Mobile Support For Learning By Doing In The Real World, Ray Bareiss, Natalie Linnell, Martin Griss
Ray Bareiss
This research addresses the use of mobile devices with both embedded and external sensors to provide contextualized help, advice, and remediation to learners engaged in real-world learn-by-doing tasks. This work is situated within the context of learning a complex procedure, in particular emergency responders learning to conduct urban search and rescue operations. Research issues include the design and delivery of contextualized performance support and the inferring of learner actions and intentions from sensor data to ensure that the right support is delivered just in time, as it is relevant to what the learner is doing.
