Counting Seconds

Each of my oil or pastel paintings is an observation of seemingly mundane familiar places that I encounter day-to-day. I think of my art as a kind of visual journalism, where I examine common human emotions evoked by a careful consideration of the substance of light interacting with spaces or objects. The naturalistically rendered compositions are cropped and depicted in small fragments, allowing the viewer a brief glimpse into a quiet portrayal of the world. Essentially, my art allows me to share my sensibilities and to connect with others through portraits of ordinary, yet intimate, moments in time.

Crisis and Culture (open access)

Crisis and Culture

The research seeks to know if the COVID-19 pandemic has created culture change by measuring the criteria of work outputs and actions of organization members. As a part of this research, a survey was developed to identify how and to what extent workplace culture has been impacted. 111 professional services staff from a North Texas business were surveyed. We identified three factors for criteria of work outputs and behavior that indicates the current level of change of the culture. The three factors are identified as, Expectations (α= 0.786), Accuracy (α= 0.603), and Timeliness (α= 0.552). Factor analysis and descriptive statistics are used to analyze the result from the survey.

The Gainsay Taxonomies (open access)

The Gainsay Taxonomies

Through painting, I use materiality to describe the material world. By rooting my practice in visual culture and art history, I seek to extend the meaning of images beyond their initial form. The coalescing of opposing and complimentary formal elements accentuate the visual and contextual friction. This allows the work to exist in an ambiguous state. Seen together, my works appear disparate, but they suggest alternative meanings through association with one another. The works can exist on their own, but engage in dialogue when juxtaposed against each other. Although about specific occurrences, the works afford the viewer their own interpretations.

Memory Beast (open access)

Memory Beast

Memory Beast was a series of experiments in multispecies collaborative storytelling. A new tool was created, a memory beast, a holotype representing our ideas of specific species, based on memories and drawings collected in participatory research. The fabricated memory beasts, placed next to their biological counterparts, made visible the conflation of living species with personal memory and cultural imagery. Using this new tool, implanted with sonic recordings of cows, the beginnings of an interspecies pidgin language was developed. Memory Beast imagined and enacted new pathways to finite flourishing on a wounded earth, planting story seeds for alternative realities.

Kaugnayan (Connections)

Artist Statement from the MFA Exhibition: "In my recent work, I have expanded upon the deconstruction, reconstruction, and reflection that has informed my artistic process for many years. My working method involves using remnants from previous works; they reappear in their original form or are reworked, aged destroyed, or recreated from different materials. My Process allows me to illustrate the passage of time as older work takes on new forms in a renewed context. New connections begin to surface as my paintings and accompanying objects are layered into a work about the passage of time as well as other passages; a migratory mentality know to all who live away from home."

Critical Discussion of Pleroma: A Digital Drama and Its Relevance to Tragic Form in Music captions transcript

Critical Discussion of Pleroma: A Digital Drama and Its Relevance to Tragic Form in Music

Pleroma is a digital drama: a work composed of digital animation combined with electroacoustic music, presenting an original dramatic narrative. Pleroma's dramatic elements evoke both the classical form of tragedy and the concept of perceptual paradox. A structural overview of the drama and its characters and a plot synopsis are given to provide context for the critical discussion. Analytical descriptions of Beethoven's Coriolan Overture Op.62 and Mahler's Symphony No. 9 are provided to give background on tragic form and Platonic allegory in music. An investigation into the elements discussed in the analysis of the instrumental works reveals several layers of possible interpretation in Pleroma. Dramatic elements allow for tragic narratives to be constructed, but they are complemented by character associations formed by pitch relationships, stylistic juxtapositions, and instrumentation. A copy of the dramatic text is included to supplement the multimedia production: http://digital.library.unt.edu/ark:/67531/metadc33228/

Beads on a String: Extended Portraits (open access)

Beads on a String: Extended Portraits

When I was first introduced to photography, I was mainly drawn to landscape imagery. I enjoyed being a solitary spectator. Over time, inclusions of figurative elements became more and more apparent in my work. I purposefully began to incorporate a figure into my landscapes, ascribing to it a certain nostalgia and a sense of isolation I was experiencing on many levels at that time. Before long, I felt disconnected from these images because of their ambiguity and generalization. I found myself craving more content and personal commitment in my photography. At the end 2003, I started experimenting with a 4" x 5" format camera, which forced me, to some extent, to change my way of photographing and seeing. That is how the beginning of this new body of work was born. I was accustomed to shooting with a 35 mm camera, which allowed me to be spontaneous, quick and immediate. I permanently switched to a large format. I could see myself benefiting from this change. I lost some of the spontaneity that a 35 mm format offers but I gained the beauty of working with larger negatives and the endless possibilities of view camera movements. Thanks to this technical transformation, …

Brownian Movement and Quantum Computers

Access: Use of this item is restricted to the UNT Community
This problem in lieu of thesis is a discussion of two topics: Brownian movement and quantum computers. Brownian movement is a physical phenomenon in which the particle velocity is constantly undergoing random fluctuations. Chapters 2, 3 and 4, describe Brownian motion from three different perspectives. The next four chapters are devoted to the subject of quantum computers, which are the signal of a new era of technology and science combined together. In the first chapter I present to a reader the two topics of my problem in lieu of thesis. In the second chapter I explain the idea of Brownian motion, its interpretation as a stochastic process and I find its distribution function. The next chapter illustrates the probabilistic picture of Brownian motion, where the statistical averages over trajectories are related to the probability distribution function. Chapter 4 shows how to derive the Langevin equation, introduced in chapter 1, using a Hamiltonian picture of a bath with infinite number of harmonic oscillators. The chapter 5 explains how the idea of quantum computers was developed and how step-by-step all the puzzles for the field of quantum computers were created. The next chapter, chapter 6, discus the basic quantum unit of information …

Peptide-based hidden Markov model for peptide fingerprint mapping.

Access: Use of this item is restricted to the UNT Community
Peptide mass fingerprinting (PMF) was the first automated method for protein identification in proteomics, and it remains in common usage today because of its simplicity and the low equipment costs for generating fingerprints. However, one of the problems with PMF is its limited specificity and sensitivity in protein identification. Here I present a method that shows potential to significantly enhance the accuracy of peptide mass fingerprinting, using a machine learning approach based on a hidden Markov model (HMM). This method is applied to improve differentiation of real protein matches from those that occur by chance. The system was trained using 300 examples of combined real and false-positive protein identification results, and 10-fold cross-validation applied to assess model discrimination. The model can achieve 93% accuracy in distinguishing correct and real protein identification results versus false-positive matches. The receiver operating characteristic (ROC) curve area for the best model was 0.833.

Transplants

Access: Use of this item is restricted to the UNT Community
The body of work originating from this Problem in Lieu of Thesis consists of paintings on canvas that incorporate representations of plant material. The impetus for the paintings was black and white photocopies created from mounds of plant material placed on a copy machine. The resulting copies contained forms that were organic in appearance, but unrecognizable as known objects. Parts of the most interesting and ambiguous copies were used to develop the imagery of the paintings. The new forms served the purpose of creating visual interest from unexpected images. Combined with traditional painting techniques, the selected forms produced paintings of mysterious and playful worlds similar to those parts of the environment not readily accessed, such as galactic space, microscopic organisms, and ocean depths.

Voting Operating System (VOS)

Access: Use of this item is restricted to the UNT Community
The electronic voting machine (EVM) plays a very important role in a country where government officials are elected into office. Throughout the world, a specific operating system that tends to the specific requirement of the EVM does not exist. Existing EVM technology depends upon the various operating systems currently available, thus ignoring the basic needs of the system. There is a compromise over the basic requirements in order to develop the systems on the basis on an already available operating system, thus having a lot of scope for error. It is necessary to know the specific details of the particular device for which the operating system is being developed. In this document, I evaluate existing EVMs and identify flaws and shortcomings. I propose a solution for a new operating system that meets the specific requirements of the EVM, calling it Voting Operating System (VOS, pronounced 'voice'). The identification technique can be simplified by using the fingerprint technology that determines the identity of a person based on two fingerprints. I also discuss the various parts of the operating system that have to be implemented that can tend to all the basic requirements of an EVM, including implementation of the memory manager, …

Ballistic Deposition: Global Scaling and Local Time Series. (open access)

Ballistic Deposition: Global Scaling and Local Time Series.

Complexity can emerge from extremely simple rules. A paradigmatic example of this is the model of ballistic deposition (BD), a simple model of sedimentary rock growth. In two separate Problem-in-Lieu-of Thesis studies, BD was investigated numerically in (1+1)-D on a lattice. Both studies are combined in this document. For problem I, the global interface roughening (IR) process was studied in terms of effective scaling exponents for a generalized BD model. The model used incorporates a tunable parameter B to change the cooperation between aggregating particles. Scaling was found to depart increasingly from the predictions of Kardar-Parisi-Zhang theory both with decreasing system sizes and with increasing cooperation. For problem II, the local single column evolution during BD rock growth was studied via statistical analysis of time series. Connections were found between single column time series properties and the global IR process.

Deposition and Characterization of Pentacene Film. (open access)

Deposition and Characterization of Pentacene Film.

Many organic materials have been studied to be used as semiconductors, few of them being pentacene and polythiophene. Organic semiconductors have been investigated to make organic thin film transistors. Pentacene has been used in the active region of the transistors. Transistors fabricated with pentacene do not have very high mobility. But in some applications, high mobility is not needed. In such application other properties of organic transistors are used, such as, ease of production and flexibility. Organic thin film transistors (OTFT) can find use as low density storage devices, such as smart cards or I.D. tags, and displays. OTFT are compatible with polymeric substrates and hence can find use as flexible computer screens. This project aims at making 'smart clothes', the cheap way, with pentacene based OTFT. This problem in lieu of thesis describes a way to deposit pentacene films and characterize it. Pentacene films were deposited on substrates and characterized using x-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The substrate used was ~1500Å platinum on silicon wafer or bare silicon wafer. was used. A deposition system for vacuum deposition of pentacene was assembled. The XRD data for deposited pentacene films shows the presence of two phases, single …

Fashion Circles (open access)

Fashion Circles

Through this body of work and this paper the possibilities of using Fashion Design to express the concepts of the circle has been explored. This was done with three questions in mind: How can I use the shape of the circle as inspiration for fashion design? How can I express related words and phrases in my design? and How can I use the colors black and white to emphasize the concept of my design. To answer these questions I have created two groups of garments: one was inspired by circular objects, such as cherries and drops, and the other starting from words and phrases such as "study circle" and "circle the wagons." In the first group the emphasis was on the aesthetics of the garment while the second group was more focused on meaning. All garments are black and white.

Machine Language Techniques for Conversational Agents

Machine Learning is the ability of a machine to perform better at a given task, using its previous experience. Various algorithms like decision trees, Bayesian learning, artificial neural networks and instance-based learning algorithms are used widely in machine learning systems. Current applications of machine learning include credit card fraud detection, customer service based on history of purchased products, games and many more. The application of machine learning techniques to natural language processing (NLP) has increased tremendously in recent years. Examples are handwriting recognition and speech recognition. The problem we tackle in this Problem in Lieu of Thesis is applying machine-learning techniques to improve the performance of a conversational agent. The OpenMind repository of common sense, in the form of question-answer pairs is treated as the training data for the machine learning system. WordNet is interfaced with to capture important semantic and syntactic information about the words in the sentences. Further, k-closest neighbors algorithm, an instance based learning algorithm is used to simulate a case based learning system. The resulting system is expected to be able to answer new queries with knowledge gained from the training data it was fed with.
