Cloud Composition Technologies In Multimodal Composition Program Documents, Philippe Peter Meister

Graduate Theses and Dissertations

Writing programs at numerous universities—including the Georgia Institute of Technology, Iowa State University, Miami University of Ohio, Virginia Tech, and Purdue University—are incorporating more learning about multimodal communication into their curricula, including written, oral, visual, and electronic communication (WOVE). Within WOVE, electronic technologies enable students to produce, distribute, and consume written, visual, oral, and electronic communication (Ong 1982; Bush 1945; Eisenstein 1979, Lauer 2009, 2014). Integrating cloud technologies into writing programs may be difficult because it requires ongoing training, support, and maintenance, but it may be worthwhile because it helps produce a writing culture mediated by these technologies ...


Digital Integration, Jacob C. Boccio Jun 2016

Digital Integration, Jacob C. Boccio

Graduate Theses and Dissertations

Artificial intelligence is an emerging technology; something far beyond smartphones, cloud integration, or surgical microchip implantation. Utilizing the work of Ray Kurzweil, Nick Bostrom, and Steven Shaviro, this thesis investigates technology and artificial intelligence through the lens of the cinema. It does this by mapping contemporary concepts and the imagined worlds in film as an intersection of reality and fiction that examines issues of individual identity and alienation. I look at a non-linear timeline of films involving machine advancement, machine intelligence, and stages of post-human development; Elysium (2013) and Surrogates (2009) are about technology as an extension of the self ...

Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan Jan 2016

Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan

Graduate Theses and Dissertations

We study the problem of detecting non - termination in multi - threaded programs due to unwanted race conditions. We claim that the cause of non-termination can be attributed to the presence of at least two loops in two different threads, where the valuations of the loop controlling parameters are inter-dependent, i.e., value of one parameter in one thread depends on the execution sequence in the other thread and vice versa. In this thesis, we propose a testing based technique to analyze finite execution sequences and infer the likelihood of non-termination scenarios. Our technique is a light weight, flexible testing based ...


Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre Jan 2015

Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre

Graduate Theses and Dissertations

Agency is a foundational and ongoing concern for the field of Rhetoric and Composition. Long thought to be a product and possession of human action, rhetorical agency represents the most obvious connection between the educational and theoretical work of the field and the civic project of liberal arts and humanities education. Existing theories of anthropocentric rhetorical agency are insufficient, however, to account for the complex technological work of digitally enmeshed networks of humans and nonhumans. To better account for these complex networks, this project argues for the introduction of new materialist theories of distributed agency into conversations about agency within ...

Nobile: Design And Evaluation Of A Persuasive Technology Application For Social Behavior Change, Batzaya Batsaikhan

Graduate Theses and Dissertations

Modern society is becoming increasingly connected and more and more technology-enabled. Communication technology is as portable as ever, thus rapidly proliferating, and not surprisingly, many carry at least one or more communication technologies, such as smartphones and tablets, with them on a daily basis, giving the means of constant connection. As a result, this constant connectivity has been discreetly disrupting not only how communication occurs between people but also lives. People come together but barely speak to each other. Rather, they rely on technology, for instance, smartphones, for companionship, and this may have negative consequences on one's social life ...


Defining A Software Genre: Timeline Navigators, Eduardo Rubio Jan 2014

Defining A Software Genre: Timeline Navigators, Eduardo Rubio

Graduate Theses and Dissertations

This research defines a widely used, but largely unrecognized genre of software. From a User Experience Design standpoint, this genre definition considers any application that helps users capture, understand, and manipulate time-series data.

Computer user interfaces investigated within this genre help users manage time-series data. Digital interactions with time-series data range from simple presses of the play/pause button, loops to find the right information, to complex analyses necessary for greater understanding. A child may watch a movie played on a media player like Apple's iTunes. A student may compose a musical presentation with Steinberg's Cubase. Trying to ...

A Principled Approach To Policy Composition For Runtime Enforcement Mechanisms, Zachary Negual Carter Jan 2012

A Principled Approach To Policy Composition For Runtime Enforcement Mechanisms, Zachary Negual Carter

Graduate Theses and Dissertations

Runtime enforcement mechanisms are an important and well-employed method for ensuring an execution only exhibits acceptable behavior, as dictated by a security policy. Wherever interaction occurs between two or more parties that do not completely trust each other, it is most often the case that a runtime enforcement mechanism is between them in some form, monitoring the exchange. Considering the ubiquity of such scenarios in the computing world, there has been an increased effort to build formal models of runtime monitors that closely capture their capabilities so that their effectiveness can be analysed more precisely. While models have grown more ...

Algorithms For Visual Maritime Surveillance With Rapidly Moving Camera, Sergiy Fefilatyev

Graduate Theses and Dissertations

Visual surveillance in the maritime domain has been explored for more than a decade. Although it has produced a number of working systems and resulted in a mature technology, surveillance has been restricted to the port facilities or areas close to the coastline assuming a fixed-camera scenario. This dissertation presents several contributions in the domain of maritime surveillance. First, a novel algorithm for open-sea visual maritime surveillance is introduced. We explore a challenging situation with a camera mounted on a buoy or other floating platform. The developed algorithm detects, localizes, and tracks ships in the field of view of the ...


Overcoming Limitations Of Serial Audio Search, Isabela Cordeiro Ribeiro Moura Hidalgo Jan 2012

Overcoming Limitations Of Serial Audio Search, Isabela Cordeiro Ribeiro Moura Hidalgo

Graduate Theses and Dissertations

The typical approach for finding audio recordings, such as music and sound effects, in a database is to enter some textual information into a search field. The results appear summarized in a list of textual descriptions of the audio files along with a function for playing back the recordings. Exploring such a list sequentially is a time-consuming and tedious way to search for sounds. This research evaluates whether searching for audio information can become more effective with a user interface capable of presenting multiple audio streams simultaneously.

A prototype audio player was developed with a user interface suitable for both ...


A Location-Based Incentive Mechanism For Participatory Sensing Systems With Budget Constraints, Luis Gabriel Jaimes Jan 2012

A Location-Based Incentive Mechanism For Participatory Sensing Systems With Budget Constraints, Luis Gabriel Jaimes

Graduate Theses and Dissertations

Participatory Sensing (PS) systems rely on the willingness of mobile users to participate in the collection and reporting of data using a variety of sensors either embedded or integrated in their

cellular phones. Users agree to use their cellular phone resources to sense and transmit the data of interest because these data will be used to address a collective problem that otherwise would

be very difficult to assess and solve. However, this new data collection paradigm has not been very successful yet mainly because of the lack of incentives for participation and privacy concerns. Without adequate incentive and privacy guaranteeing ...

A Framework For Participatory Sensing Systems, Diego Mendez Chaves Jan 2012

A Framework For Participatory Sensing Systems, Diego Mendez Chaves

Graduate Theses and Dissertations

Participatory sensing (PS) systems are a new emerging sensing paradigm based on the participation of cellular users in a cooperative way. Due to the spatio-temporal granularity that a PS system can provide, it is now possible to detect and analyze events that occur at different scales, at a low cost. While PS systems present interesting characteristics, they also create new problems. Since the measuring devices are cheaper and they are in the hands of the users, PS systems face several design challenges related to the poor accuracy and high failure rate of the sensors, the possibility of malicious users tampering ...

A Spatially Explicit Agent Based Model Of Muscovy Duck Home Range Behavior, James Howard Anderson Jan 2012

A Spatially Explicit Agent Based Model Of Muscovy Duck Home Range Behavior, James Howard Anderson

Graduate Theses and Dissertations

ABSTRACT

Research in GIScience has identified agent-based simulation methodologies as effective in the study of complex adaptive spatial systems (CASS). CASS are characterized by the emergent nature of their spatial expressions and by the changing relationships between their constituent variables and how those variables act on the system's spatial expression over time. Here, emergence refers to a CASS property where small-scale, individual action results in macroscopic or system-level patterns over time. This research develops and executes a spatially-explicit agent based model of Muscovy Duck home range behavior. Muscovy duck home range behavior is regarded as a complex adaptive spatial ...


Methods And Algorithms For Scalable Verification Of Asynchronous Designs, Haiqiong Yao Jan 2012

Methods And Algorithms For Scalable Verification Of Asynchronous Designs, Haiqiong Yao

Graduate Theses and Dissertations

Concurrent systems are getting more complex with the advent of multi-core processors and the support of concurrent programs. However, errors of concurrent systems are too subtle to detect with the traditional testing and simulation. Model checking is an effective method to verify concurrent systems by exhaustively searching the complete state space exhibited by a system. However, the main challenge for model checking is state explosion, that is the state space of a concurrent system grows exponentially in the number of components of the system. The state space explosion problem prevents model checking from being applied to systems in realistic size ...


Extraction Of Text Objects In Image And Video Documents, Jing Zhang Jan 2012

Extraction Of Text Objects In Image And Video Documents, Jing Zhang

Graduate Theses and Dissertations

The popularity of digital image and video is increasing rapidly. To help users navigate libraries of image and video, Content Based Information Retrieval (CBIR) system that can automatically index image and video documents are needed. However, due to the semantic gap between low-level machine descriptors and high-level semantic descriptors, the existing CBIR systems are still far from perfect. Text embedded in multi-media data, as a well-defined model of concepts for humans' communication, contains much semantic information related to the content. This text information can provide a much truer form of content-based access to the image and video documents if it ...


Using A Focus Measure To Automate The Location Of Biological Tissue Surfaces In Brightfield Microscopy, Daniel Toby Elozory Jan 2011

Using A Focus Measure To Automate The Location Of Biological Tissue Surfaces In Brightfield Microscopy, Daniel Toby Elozory

Graduate Theses and Dissertations

The study of microstructures in brightfield microscopy using unbiased stereology plays a large and growing role in bioscience research. Stereology enables objective quantitative analysis of biological structures within a tissue sample. A first step in the stereology process is to calculate the thickness of a tissue sample by locating the top and bottom surfaces of the sample. The aim of this project is to fully automate this location process by using the relative optical focus measure as an indicator of tissue surface boundary.

The current method for identification of focus bounding planes requires a trained user to manually select the ...


An Analysis Of Remote Biometric Authentication With Windows, Brandy Marie Eyers Jan 2011

An Analysis Of Remote Biometric Authentication With Windows, Brandy Marie Eyers

Graduate Theses and Dissertations

One thing that everyone seems to be worried about when it comes to his or her computer is security. If your computer is not secure then private information could be stolen. Many people now use passwords to protect themselves though they are discovering that using multi-factor authentication is much more secure. It allows you to use multiple different proofs of who you are. Biometrics is one of the ways to prove identity. Using it, you could log into a system with just a fingerprint, which is something that is very difficult to steal. We present a suite of software tools ...


Automated Quantification Of Biological Microstructures Using Unbiased Stereology, Om Pavithra Bonam Jan 2011

Automated Quantification Of Biological Microstructures Using Unbiased Stereology, Om Pavithra Bonam

Graduate Theses and Dissertations

Research in many fields of life and biomedical sciences depends on the microscopic image analysis of biological images. Quantitative analysis of these images is often time-consuming, tedious, and may be prone to subjective bias from the observer and inter /intra observer variations. Systems for automatic analysis developed in the past decade determine various parameters associated with biological tissue, such as the number of cells, object volume and length of fibers to avoid problems with manual collection of microscopic data. Specifically, automatic analysis of biological microstructures using unbiased stereology, a set of approaches designed to avoid all known sources of systematic ...


Optimization Of Proximity Judgment, Brian Day Jan 2011

Optimization Of Proximity Judgment, Brian Day

Graduate Theses and Dissertations

As humans, we have evolved to see in three dimensions. Our ancestors developed two eyes that only look forward, which allows the visual area that can perceive depth to be most of the field of view. A variety of sensors have been developed which can determine depth in the environment. They range from producing individual points of depth to the depth of everything in the environment. These sensors have become cheap and can now reliably produce accurate depth. Research is needed to determine how to present the proximity information to the people using the sensors. Touch, sound, and vision have ...

Our proposed approach involves generating a density point cloud based on the intensity ...


Live Video Streaming From Android-Enabled Devices To Web Browsers, Justin M. Bailey Jan 2011

Live Video Streaming From Android-Enabled Devices To Web Browsers, Justin M. Bailey

Graduate Theses and Dissertations

The wide-spread adoption of camera-embedded mobile devices along with the ubiquitous connection via WiFi or cellular networks enables people to visually report live events. Current solutions limit the configurability of such services by allowing video streaming only to fixed servers. In addition, the business models of the companies that provide such (free) services insert visual ads in the streamed videos, leading to unnecessary resource consumption.

This thesis proposes an architecture of a real-time video streaming service from an Android mobile device to a server of the user's choice. The real-time video can then be viewed from a web browser ...
