A Sentence Need Not Begin With A Capital Letter, Jakob Patekar

Articles

This paper examines the challenge of starting a sentence with a proper noun or an abbreviation that is written with an initial lowercase letter (e.g. iPhone, danah boyd, pH). Traditionally, placing such words at the beginning of a sentence would be avoided, but this limits one's syntax and style. Hence, the aim of this paper is to explore the rules and practices of writing certain proper nouns and abbreviations with a lowercase letter and starting a sentence with such words in Croatian and English. Therefore, we reviewed the rules and guidelines in orthography handbooks and style guides, analyzed the corpora …

Employing Optical Flow On Convolutional Recurrent Structures For Deepfake Detection, Akash Chintha

Theses

Deepfakes, or artificially generated audiovisual renderings, can be used to defame a public figure or influence public opinion. With the recent discovery of generative adversarial networks, an attacker using a normal desktop computer fitted with an off-the-shelf graphics processing unit can make renditions realistic enough to easily fool a human observer. Detecting deepfakes is thus becoming vital for reporters, social networks, and the general public. Preliminary research introduced simple, yet surprisingly efficient digital forensic methods for visual deepfake detection. These methods combined convolutional latent representations with bidirectional recurrent structures and entropy-based cost functions. The latent representations for the video are …

Immigration, Crime, And Policy, Tiara Grayson

Theses

When viewing the criminal justice system, it is always investigated through a criminological approach. Meaning, there are numerous studies that attempt to get an understanding of why crime occurs, rather than the “why” in regards to the criminal justice system. The actors of the criminal justice system and their methods of crime control are rarely examined. In this paper, I will examine the behaviors of those who are attached to the criminal justice system; this includes the police, the media, politicians, and the public, who all play a role in how the criminal justice system functions, regarding immigration. Studying the …

Low Frequency Cyclical Potentials For Fine Tuning Nonlinear Electrokinetic Separations, Cody Justice Lentz

Theses

This work has shown a novel method for the separation of particles inside a nonlinear EK device using low frequency cyclical signals. The utility of this method was demonstrated by successfully separating micron sized polystyrene particles based on differences in particle size (2 µm vs. 5.1 µm) and by differences in particle charge (19 vs. 60 mv). In order to discover a usable signal for separation, a custom Matlab program was developed to simulate particle migration inside the device. The custom program utilized data from finite element analysis of the electric field in the device using the COMSOL Multiphysics program. …

Human-In-The-Loop Learning From Crowdsourcing And Social Media, Tong Liu

Theses

Computational social studies using public social media data have become more and more popular because of the large amount of user-generated data available. The richness of social media data, coupled with noise and subjectivity, raise significant challenges for computationally studying social issues in a feasible and scalable manner. Machine learning problems are, as a result, often subjective or ambiguous when humans are involved. That is, humans solving the same problems might come to legitimate but completely different conclusions, based on their personal experiences and beliefs. When building supervised learning models, particularly when using crowdsourced training data, multiple annotations per data …

Interactive Range Queries Under Differential Privacy, Asma Mohammed Alnemari

Theses

Differential privacy approaches employ a curator to control data sharing with analysts without compromising individual privacy. The curator’s role is to guard the data and determine what is appropriate for release using the parameter epsilon to adjust the accuracy of the released data. A low epsilon value provides more privacy, while a higher epsilon value is associated with higher accuracy. Counting queries, which ”count” the number of items in a dataset that meet specific conditions, impose additional restrictions on privacy protection. In particular, if the resulting counts are low, the data released is more specific and can lead to privacy …

Integrated Framework For Data Quality And Security Evaluation On Mobile Devices, Igor Khokhlov

Theses

Data quality (DQ) is an important concept that is used in the design and employment of information, data management, decision making, and engineering systems with multiple applications already available for solving specific problems. Unfortunately, conventional approaches to DQ evaluation commonly do not pay enough attention or even ignore the security and privacy of the evaluated data. In this research, we develop a framework for the DQ evaluation of the sensor originated data acquired from smartphones, that incorporates security and privacy aspects into the DQ evaluation pipeline. The framework provides support for selecting the DQ metrics and implementing their calculus by …

Self-Supervised Video Representation Learning By Recurrent Networks And Frame Order Prediction, Sai Shashidhar Nagabandi

Theses

The success of deep learning models in challenging tasks of computer vision and natural language processing depend on good vector representations of data. For example, learning efficient and salient video representations is one of the fundamental steps for many tasks like action recognition and next frame prediction. Most methods in deep learning rely on large datasets like ImageNet or MSCOCO for training, which is expensive and time consuming to collect. Some of the earlier works in video representation learning relied on encoder-decoder style networks in an unsupervised fashion, which would take in a few frames at a time. Research in …

Prediction Of Gas-Hydrate Equilibrium, Stability And Kinetic Nucleation In Porous Media, Yali Zhang

Theses

Natural gas-hydrates are crystalline inclusion compounds with gas molecules (guest compounds) trapped within a host lattice formed by water molecules in an ice-like hydrogen-bonded framework. Natural gas-hydrates have the potential to become an important carbon-based resource addressing the increasing energy demand, and they pose a risk in terms of climate change. Accurate estimates of gas-hydrates global inventory, understanding of formation and dissociation processes of gas-hydrates, and evaluation of their environmental impact require models that accurately describe gas-hydrate stability in sediments and predict gas-hydrate kinetic nucleation processes. The hypothesis driving this work is that incorporation of selected sediment properties, i.e., surface …

[Iteration 2491-J], Jeff Leavitt

Theses

When one considers the macro scale of human existence, it is ultimately a never-ending cycle of futility. We are born, some of us reproduce, and then we die. No matter what exists within that cycle, those facts remain true. However, a futile existence does not have to be a meaningless one. When one considers the micro scale of human existence, there is beauty and joy within the lives of individuals. Individuality is an essential component our existence, and it allows us to spend our time on this planet in a meaningful way. Futility, as a concept, is not inherently pessimistic. …
