Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh Jun 2023

Exploring The Use Of Virtual Reality In Designing And Prototyping Medical Devices, Evan Marsh

Honors Theses

A degree in engineering is highly sought after in the United States. Despite the grueling coursework and sacrifices involved in earning an engineering degree, the rewards after college are numerous. However, the engineering field is vast, and the degree obtained is not always the profession followed in industry. A lot of what we learn in the college of engineering is very broad and surface-level. It is worth noting that only about 10% of what engineering students learn in school is applicable in the workplace, but they wish they had learned a lot more about that 10%.


A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage Apr 2023

A Device For Measuring Acoustic Output Intensity Of Transcranial Doppler Ultrasound Transducers For Comparison With Fda Regulations, Sarah Altman, Gregory Bashford, Benjamin Hage

Honors Theses

Transcranial Doppler Ultrasonography (TCD) is a non-invasive methodology which can evaluate cerebral blood flow velocity in real time. Single-element focused circular transducers placed on the scalp produce ultrasound waves capable of penetrating the skull with minimal aberration, enabling measurement of the Doppler shift. As such, TCD can measure blood flow velocity in the internal carotid and vertebral arteries, as well as the arteries of the Circle of Willis: the Anterior Cerebral (ACA), Posterior Cerebral (PCA), and Middle Cerebral Arteries (MCA). Intracranial aneurysm and ischemic stroke are serious conditions in which ballooning or occlusion of cerebral vessels cause insufficient perfusion, leading …


Biomechanical Analysis Of Athletes Sprinting With Varying Degrees Of Resistance, Michaela Ott Apr 2022

Biomechanical Analysis Of Athletes Sprinting With Varying Degrees Of Resistance, Michaela Ott

Honors Theses

Utilizing resistance methods for sprinters is a common approach to their training. In this study, six athletes from the University of Nebraska-Lincoln Women’s Track and Field Team ran a series of sprints using a resistance machine to collect data regarding the change in power output, stride length, level of trunk tilt with respect to the ground, and acceleration throughout a distance of ten meters when different amounts of resistant forces were applied to the athlete. It was hypothesized that as resistance increased, power output would increase, stride length would decrease, the runners would become more horizontal resulting in a larger …


Two-Dimensional & Three-Dimensional Microarray Cell Culture Using Elastomeric Assembly Substrates, Angel Olivera-Torres Jan 2021

Two-Dimensional & Three-Dimensional Microarray Cell Culture Using Elastomeric Assembly Substrates, Angel Olivera-Torres

Honors Theses

Tissue engineering and regenerative medicine represent the collection of all engineering disciplines brought together for the common goal of developing novel ways of growing tissues and organs in the laboratory. Efforts have made it possible to replicate or induce growth of 2D structures in the human body like skin, but the clinical need for on-demand solid organs has yet to be met due to lack of understanding of the variables responsible for organogenesis. Cell-colony heterogeneity, 3D-cellular architecture, bioactive molecules, and crosstalk communication between parenchymal cell populations need to be further investigated, and high-throughput technologies can rapidly increase the rate at …


Designing A Week-Long Biomedical Engineering Summer Camp To Increase Young Students’ Interest And Self-Efficacy In Stem, Kayla Ney Oct 2020

Designing A Week-Long Biomedical Engineering Summer Camp To Increase Young Students’ Interest And Self-Efficacy In Stem, Kayla Ney

Honors Theses

In order to combat the negative feelings many young students have towards STEM, I designed a week-long summer camp that teaches students about biomedical engineering as well as collaboration, communication, and confidence with STEM subjects. This work includes a literature review outlining what STEM is and current issues in STEM education, including disinterest in STEM and attrition in STEM degree programs. The literature review outlines current methods and ideas being utilized to combat these issues, namely, inclusive pedagogical strategies, and how some of these concepts can be applied to the summer camp. The curriculum document included outlines each activity, its …


Dynamic Classification Of Moisture Stress Using Canopy And Leaf Temperature Responses To A Step Changes Of Incident Radiation, Erin E. Stevens, George E. Meyer, Ellen T. Paparozzi Apr 2018

Dynamic Classification Of Moisture Stress Using Canopy And Leaf Temperature Responses To A Step Changes Of Incident Radiation, Erin E. Stevens, George E. Meyer, Ellen T. Paparozzi

Honors Theses

Environmental conditions affect plant productivity and understanding how plants respond to drought stress can be measured in different ways. This study focused on measuring leaf response time to induced water stress. Leaf response time to a step increase and step decrease in radiation was computed for four species of well-watered and water-stressed plants in a controlled environment. The canopy temperature was measured with an infrared thermometer and a thermal imaging camera. Thermal images were analyzed to determine the average temperature of a selected single, unobstructed leaf at the top of the canopy. Both the canopy response time and the single …

A Strategic Audit Of Medtronic Plc, Jozzy Carter

Honors Theses

Humans will always have a need for healthcare, and as the world continues to innovate in the tech space, consumers will demand advances in medicine and medical devices. Medtronic is at the forefront of this innovation but faces intense competition in the medical technologies industry. This poses the question: what can Medtronic do to continue its growth and stay competitive in this space? This paper offers an analysis of Medtronic as a medical device company by offering insight to its competitive advantage, financials, business mix, and value chain. It also analyzes the forces that affect Medtronic using SWOT, PEST, and …


Chitosan Nanoparticle Modifications For Improved Gene Delivery In An Oral Dna Vaccine Application, Austin Helmink Apr 2017

Chitosan Nanoparticle Modifications For Improved Gene Delivery In An Oral Dna Vaccine Application, Austin Helmink

Honors Theses

Vaccines represent one of the most significant medical innovations of the 20th century, resulting in the eradication or near eradication of a handful of deadly diseases. However, many infectious diseases remain resistant to effective vaccination, largely due to a lack full immune activation by traditional protein-based vaccines. A promising alternative vaccination strategy is the emerging development of DNA vaccines, which rely upon the delivery of exogenous genetic material to host cells encoding for a viral or bacterial antigen in order to induce a robust immune response by closely mimicking live infection. The delivery of genetic material requires a carrier …
