Karinganire Umutesi: capstone
No full text2023 Spring.Colorado State University Art and Art History Department capstone project.Capstone contains the artist's statement, a list of works, and images of works.The artist's statement: My name is Karinganire Umutesi, but I go by Umutesi. Growing up, I have always been interested in storytelling and business. I am a graphic designer, an illustrator, and a storyteller, and an entrepreneur who's also passionate about African Cultures. Growing up, I always found myself buying hundreds of sketchbooks and exploring my surroundings through drawing and illustration. What I love about Graphic Design is the power you get from it, for design can communicate to a large mass even if there are cultural, linguistic, or geographic differences. My goal is to use design as a gateway for people without a voice, to show their stories and their truth
Brooke Bryan: capstone
No full text2023 Spring.Colorado State University Art and Art History Department capstone project.Capstone contains the artist's statement, a list of works, and images of works.The artist's statement: My name is Brooke Bryan. I desire to communicate truth and beauty through my work. My work is my exploration of testing what I see in the world for myself. Maybe I'm inspired by an animal's fur pattern, or the colors in a flower garden. Other artists have discovered such fantastic methods to create, and I enjoy following their methods to see if I like it, where I can implement it, and then make it my own. Each person has such a unique perspective on the world and unique gifts. I enjoy bringing traditional media into my work, since I started my love of art with pencil and paper. There is true freedom in holding the creation tool in your own hand. If I can begin my work with hand drawings and hand lettering, that's my preference. Sometimes I ink and color the drawings while still on paper. From there, I import photos of my work in the digital space and make them vector perfect. The layout is pieced together. I want to listen–to understand what my clients really want. I want to help them and learn who they are and how they want the world to perceive them. I have the ability to make what they envision, and I want to use my skills to help others
Cislunar system of systems architecture evaluation and optimization
Full text linkIncludes bibliographical references.2023 Spring.Cislunar space is the next frontier of space exploration, but a sustainable architecture is lacking. Cislunar space is considered a complex system of systems because it consists of multiple independent systems that work together to deliver unique capabilities. The independent systems of the cislunar system of systems include the communications, navigation, and domain awareness systems. Additionally, the methodology to design, evaluate and optimize a complex system of systems has not been published. To close the gap, a comprehensive needs analysis is performed for cislunar space. Next, model-based systems engineering is used to design the cislunar system of systems. The cislunar architectures are designed in terms of constellations and payloads. The architectures are each evaluated in terms of cost and performance. An appropriate optimization algorithm is found for the system of systems, and the results of the optimization are evaluated using multiple techniques for comparison. A literature review is included on the topics of cislunar architectures, system of systems, model-based systems engineering, system architecture evaluation, and system architecture optimization. During the research of cislunar architectures, a needs analysis is completed which identifies the three primary missions planned for cislunar space and eight supporting functions to provide the infrastructure for the primary missions. The primary missions identified include science, commerce, and defense. The eight supporting functions identified include transportation, communication, domain awareness, service, energy, shelter, and control. Technologies and programs are identified for each supporting function, included gaps in needed technology or programs. For the evaluation and optimization of the system of systems, the supporting functions are down-selected to include only the three necessary supporting functions for any operations in cislunar space: communications, navigation, and domain awareness. A system architecture is developed using Systems Modeling Language in Cameo Systems ModelerTM. The model is designed using the Model-based Systems Architecture Process which includes the design of the Operational Viewpoint, Logical/Functional Viewpoint, and Physical Viewpoint. The Operational Viewpoint includes structural, behavioral, data, and contextual perspectives. The Logical/Functional Viewpoint includes structural, behavioral, data, and contextual perspectives. The Physical Viewpoint includes design, standards, data, and contextual perspectives. Each of these perspectives are represented in the form of Cameo Systems ModelerTM diagrams or tables. Diagrams include block definition diagrams, internal block diagrams, use case diagrams, activity diagrams, and sequence diagrams. Additional modeling concepts beyond the Model-based Systems Architecture Process are included in the Cameo Systems ModelerTM model and analysis of the model. These topics include allocating requirements, stereotypes, patterns in architecture decisions, architecture optimization, verification, validation, complexity, and open systems architecture. Cislunar constellations and payloads are designed which account for the cislunar physical environment. Six constellations are designed to be included in the optimization algorithm. These constellations include Lagrange light, Lagrange medium, Lagrange heavy, Earth-based, Earth plus Moon, and Earth plus Lagrange. These constellations essentially represent the location of the bus while the payloads provide the functionality of the system. Payloads are designed for the supporting functions deemed essential for a basic cislunar infrastructure, which are communications, navigation, and domain awareness. The optimization algorithm runs through each possible combination of payload and bus, including any opportunities to integrate multiple payloads on a single bus. The total number of possible architecture combinations for the optimization algorithm is 288. The payload sensors are modeled in Systems Tool Kit and evaluated for physical performance. Additionally, each payload and bus possibility are evaluated for cost using the Unmanned Space Vehicle Cost Model and professional estimates. The performance and cost metrics are used in the optimization algorithm. The optimization algorithm uses multi-objective optimization with an integer linear program. The result of the optimization algorithm is a pareto front of the highest-performance, lowest-cost architectures. The architectures along the pareto front are evaluated using multi-criteria decision making with and without evidential reasoning to find the "best" architecture. A Kiviat chart assessment is also performed, though this method is shown to not be practical for the cislunar application. The model and conclusions of the dissertation are validated using a variety of industry-accepted techniques. The cislunar architectures are validated via peer-review. The performance evaluations are validated via a validated physics model. The cost evaluations are validated by a validated cost-model when possible and by peer-review. The optimization algorithm is validated by comparison to a manual optimization method. The Cameo Systems ModelerTM model is validated using validation techniques internal to the tool. Suggestions for future work are presented. Future work could include fully integrating the Cameo Systems ModelerTM model with the Systems Tool Kit model, providing improved cost estimates, using alternative optimization parameters, adding supporting functions as they are identified, evaluating the architectures using additional metrics, evaluating additional constellations, applying integration at the functional level, or assessing non-homogenous requirements
The experiences of college students in counseling during the COVID-19 pandemic
Full text link2023 Spring.Includes bibliographical references.The COVID-19 pandemic had significant impacts on communities around the globe. This created additional stressors on college students, a population known to already have significant stressors and mental health concerns. This qualitative study uses semi-structured interviews and arts-based submissions to explore the mental health counseling experiences of college students during the COVID-19 pandemic. Six participants volunteered via responses to fliers posted throughout the Colorado State University main campus. Several themes emerged following transcription and explorative-reflexive thematic analysis. Participants endorsed feelings of isolation, loss, and fear related to the pandemic. Participants also endorsed that trauma- or stressor-related concerns as well as anxiety and depression as primary reasons for seeking mental health counseling. Participants found talk therapy and aspects of the therapeutic relationship to be helpful components in their experience. Participants also stated that tangible items such as skills, frameworks, and diagnoses as important components to their experience. Participants generally had a negative view of telehealth due to feelings of disconnectedness and a lack of privacy. Overall, participants viewed mental health counseling as helpful even if some of their experiences were negative. Some implications for the counseling field and counselors include directly and clearly communicating needs and plans, incorporating activities and frameworks as a means of understanding, utilizing arts-based communication, viewing the pandemic as a clinician may view past trauma, and implementing psychoeducation and psychodrama as possible treatment methods
Hydrothermal surface modifications on titanium for biomedical applications
No full textIncludes bibliographical references.2023 Spring.Titanium and its alloys are widely used in different biomaterial applications due to their remarkable mechanical properties and bio-inertness. However, titanium-based materials still face some challenges, with an emphasis on hemocompatibility. Blood-contacting devices such as stents, heart valves, and circulatory devices are prone to thrombus formation, restenosis, and inflammation due to inappropriate blood–implant surface interactions. After implantation, when blood encounters these implant surfaces, a series of reactions takes place, such as protein adsorption, platelet adhesion and activation, and white blood cell complex formation as a defense mechanism. Currently, patients are prescribed anticoagulant drugs to prevent blood clotting, but these drugs can weaken their immune system and cause profound bleeding during injury. Extensive research has been done to modify the surface properties of titanium to enhance its hemocompatibility. Results have shown that the modification of surface morphology, roughness, and chemistry has been effective in reducing thrombus formation. A simple hydrothermal treatments with different acidic/basic medium were investigated in this dissertation. The first treatment with sodium hydroxide and the second treatment with sulfuric acid. Hemocompatability, cytocompatibility and antibacterial properties of these surfaces were investigated. The results indicated that sodium hydroxide surface is suitable for orthopedic application and sulfuric acid surface with silane coating is highly suitable for blood contacting implant surface
Ethan Strong: capstone
No full text2023 Spring.Colorado State University Art and Art History Department capstone project.Capstone contains the artist's statement, a list of works, and images of works.The artist's statement: My name is Ethan Strong, and I am a Colorado-based graphic designer with a passion for the fantastic. My work emphasizes clear communication above all else, based on my belief that graphic design is itself a form of communication as natural and important as speaking. As such, my designs take many forms, but all emphasize clear theme expressed through color, typography, and distinct use of illustration or line. I usually work with Procreate, Adobe Illustrator, and Indesign, but am familiar with a broad suite of illustration tools and am always looking to learn more. When designing for fun, most of my preferred subjects tend towards the wondrous and bizarre, with my favorite projects including design for TTRPG modules, fantasy book covers, and character designs. However, I have a broad portfolio of work, and I am happy to bring my fantastical flair to any project. When working with a client, I prioritize clear communication and setting expectations from the outset. Designs bridge the gap between a creator or vendor and their audience, and being this bridge is not a light responsibility. That being said, it's also a place of joy, and I look forward to gaining more experience visually communicating one person's or team's vision to their future consumers and fans
Effects of trace mineral source and concentration on production parameters throughout one cow-calf production cycle
Full text link2023 Spring.Includes bibliographical references.An experiment was conducted to evaluate the effects of Cu, Zn, and Mn supplementation on mineral status, production parameters, and cattle performance in a rangeland environment throughout a one -year period in eastern Colorado. One hundred and eighty multiparous crossbred (Angus and Angus x Hereford) beef cows were blocked by body weight, age, and gestational status and randomly assigned to 1 of 3 free-choice mineral treatments (n = 60 cows per treatment). Treatments were then assigned to 1 of 9 replicates (n=20 cows per replicate), resulting in 3 replicates per treatment. Treatments consisted of, 1) 1X NASEM (2016) sulfate base source, 2) 1X NASEM (2016) Intellibond source, or 3) 0.5X NASEM (2016) Intellibond source. Treatments 1 (1X Sulfate) and 2 (1X Intellibond) contained 1,000, 2,000, and 3,000 mg/kg DM of Cu, Mn, and Zn, respectively. While treatment 3 (0.5X Intellibond) contained 500, 1,000, and 1,500 mg/kg DM of Cu, Mn, and Zn. All free-choice mineral supplements were formulated to provide 0.15% supplemental S, 15 mg/kg Co from Co carbonate, and 55 mg/kg I from Ca iodate (Hubbard Feeds; Mankato, MN). Supplement consumption was formulated for 113 g·animal-1 ·d-1. Supplement intakes were determined every 28 d. Liver biopsies and blood samples were obtained before the experiment was initiated (d -45), after calving (d 158 and 159), and after weaning (d 294) at the end of the first production year. Each replicate was rotated to a different pasture every 2 to 4 weeks to minimize pasture effects. Cows were weighed during each liver biopsy event and at each scheduled handling events. A two-day calf weaning weight was collected during weaning (d 260 and 261). Over the first year of the experiment, cow BW, BCS, mineral status, mineral intake, and calf weaning weight were collected. There was no impact of treatment on any of the response variables measured during the first year of the experiment
