Constrained Optimized Command Shaping For Minimizing Residual Vibration In A Flexible-Joint Robot, Alok Agrawal Jan 2015

Constrained Optimized Command Shaping For Minimizing Residual Vibration In A Flexible-Joint Robot, Alok Agrawal

Open Access Theses

Joint flexibility is a natural trait of robotic manipulators, which limits fast point-to-point motion. Remedial measures are often employed to enable these systems to perform their goal in a desired manner. These measures range from either modifying the system dynamics such that the resonance is increasingly damped or by designing cleverly shaped input commands that avoid exciting the resonant modes altogether. In this work, a numerical framework for generating constrained shaped commands for a two-link flexible-joint robot is presented. To optimally select the design parameters for generating shaped commands, the effects of subjecting the optimization to mutually exhaustive constraints of …

Developing A Metadata Repository For Distributed File Annotation And Sharing, Samuel Wilson Jan 2015

Developing A Metadata Repository For Distributed File Annotation And Sharing, Samuel Wilson

Open Access Theses

Research data is being generated and modified at an increasingly accelerated rate. Iterations and derivations are being crafted at an almost equal velocity. With this increase comes a growing need to track the metadata about the data being generated. Where did this dataset originate? What exactly do the column headers mean? Who was the original publisher? Do I have the latest version of the data? This is to only name a few. As data is shared second or third-hand, or via alternative methods such as physical media or cloud based storage mechanisms, the veracity of the implicit metadata becomes circumstantial. …

Can We Put Photobiology To Work? Using Light To Manipulate The Nutritional And Sensory Properties Of Greenhouse Tomatoes, Michael Dzakovich

Open Access Theses

While generally viewed within the context of plant growth and development, different qualities of light are also powerful elicitors of secondary metabolic pathways in plants that affect the nutritional value and flavor of edible tissues. Leveraging fundamental photobiology principles, our studies sought to use different qualities of supplemental light including ultraviolet-B (UV-B), UV-A, blue, red, and far-red as an environmental treatment to restore garden-grown flavor and nutritional attributes to greenhouse-grown tomatoes (Solanum lycopersicum); a commercially important crop that has a poor reputation compared to its garden-grown counterparts. To test our hypotheses, we used a battery of physicochemical analyses that included …

The Role Of Snow In Soil Thermal Dynamics Of The Arctic Terrestrial Ecosystems, Zhou Lyu Jan 2015

The Role Of Snow In Soil Thermal Dynamics Of The Arctic Terrestrial Ecosystems, Zhou Lyu

Open Access Theses

The vast area of permanent or seasonal snow cover is an essential component of terrestrial ecosystems in northern mid-to-high latitudes (45-90°N), which has insulation effects on the soil layer beneath it. The affected soil thermal regimes will impact soil carbon dynamics. Recent observations indicate that there are substantial changes in both snow cover extent and duration due to climate change in the area.

Mach: A Model For Explaining Molecular And Cellular Mechanisms, Caleb M. Trujillo Jan 2015

Mach: A Model For Explaining Molecular And Cellular Mechanisms, Caleb M. Trujillo

Open Access Dissertations

Biologists use mechanistic explanations to understand behaviors of the immense complexity of molecular and cellular systems. In undergraduate biology courses, students are expected to explain molecular and cellular mechanisms, but teaching this skill presents many challenges due to the highly abstract, intangible nature of the cellular world, the influence of everyday language, and the tendency of students to overestimate how much they can explain. Therefore, across three studies this dissertation addresses these obstacles to teach undergraduate biology students to explain molecular and cellular mechanisms. ^ The first step was to model how biology experts explain molecular and cellular mechanisms, and …

Understanding Student Behaviors Using Immediate Feedback Features In A Blended Learning Environment, Xin Chen Jan 2015

Understanding Student Behaviors Using Immediate Feedback Features In A Blended Learning Environment, Xin Chen

Open Access Dissertations

Feedback serves to close the gap between learners’ current understanding and the desired understanding. Informative feedback can keep students from holding onto misconceptions, actively engage learners in knowledge acquisition, and increase confidence and motivation to learn. Yet, in the context of higher education, it is usually not possible for instructors to provide timely feedback to every individual student. This is especially difficult in first-year foundational courses due to the large number of students. Online learning platforms offer a solution by providing students immediate feedback during the course of their interactions with formative assessment tools (e.g., online homework, quizzes, embedded questions …

Impact Of L-Arginine Transportation On Myeloid-Derived Suppressor Cell Function, Cansu Cimen Bozkus

Open Access Dissertations

Inflammatory chronic prostatitis/chronic pelvic pain syndrome has been linked to autoimmune inflammation. Likewise, prostatitis has been linked to prostate cancer development and progression. A better understanding of the mechanisms by which inflammation is regulated may provide the foundation for novel approaches to controlling inflammation. Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature cells that expand during benign and cancer-associated inflammation. MDSC are characterized by their ability to potently inhibit T cell responses. Therefore, by dampening inflammation, MDSC benefit autoimmune diseases. Instead, they aggravate cancer by blocking antitumor immune responses. Identification of mechanisms underlying MDSC activities can enable the …

Characterization Of The Function Of The Dead-Box Rna Helicase Dbp2, Wai Kit Ma

Open Access Dissertations

In eukaryotes, there are highly coupled mechanisms that require RNA-binding proteins to facilitate gene expression. Proper RNA structure and ribonucleoprotein (RNP) complex formation are critical for gene expression. DEAD-box proteins are the largest class of RNA helicases that play fundamental roles in RNA and RNP structure remodeling. However, the precise biological role of the vast majority of the ~ 40 members in this family has not been completely described. Therefore, my research focused on characterizing the role of the DEAD-box RNA helicase Dbp2 during gene expression in S. cerevisiae.
