Parameter Estimation For Patient Enrollment In Clinical Trials, Junyan Liu
Parameter Estimation For Patient Enrollment In Clinical Trials, Junyan Liu
Undergraduate Honors Theses
In this paper, we study the Poisson-gamma model for recruitment time in clinical trials. We proved several properties of this model that match our intuitions from a reliability perspective, did simulations on this model, and used different optimization methods to estimate the parameters. Although the behaviors of the optimization methods were unfavorable and unstable, we identified certain conditions and provided potential explanations for this phenomenon and further insights into the Poisson-gamma model.
Co-Planar Waveguides For Microwave Atom Chips, Morgan Logsdon
Co-Planar Waveguides For Microwave Atom Chips, Morgan Logsdon
Undergraduate Honors Theses
This thesis describes research to develop co-planar waveguides (CPW) for coupling microwaves from mm-scale coaxial cables into 50 μm-scale microstrip transmission lines of a microwave atom chip. This new atom chip confines and manipulates atoms using spin-specific microwave AC Zeeman potentials and is particularly well suited for trapped atom interferometry. The coaxial-to-microstrip coupler scheme uses a focused CPW (FCPW) that shrinks the microwave field mode while maintaining a constant 50 Ω impedance for optimal power coupling. The FCPW development includes the simulation, design, fabrication, and testing of multiple CPW and microstrip prototypes using aluminum nitride substrates. Notably, the FCPW approach …
Translating Video Recordings Of Mobile App Ui Gestures Into Replayable Scenarios For Native And Hybrid Apps, Madeleine Havranek
Translating Video Recordings Of Mobile App Ui Gestures Into Replayable Scenarios For Native And Hybrid Apps, Madeleine Havranek
Undergraduate Honors Theses
Screen recordings of mobile applications are easy to obtain and capture a wealth of information pertinent to software developers (e.g., bugs or feature requests), making them a popular mechanism for crowdsourced app feedback. Thus, these videos are becoming a common artifact that developers must manage. In light of unique mobile development constraints, including swift release cycles and rapidly evolving platforms, automated techniques for analyzing all types of rich software artifacts provide benefit to mobile developers. Unfortunately, automatically analyzing screen recordings presents serious challenges, due to their graphical nature, compared to other types of (textual) artifacts. To address these challenges, this …
The Role Of Spider Silk In Peripheral Nerve Regeneration, Langston Forbes-Jackson
The Role Of Spider Silk In Peripheral Nerve Regeneration, Langston Forbes-Jackson
Undergraduate Honors Theses
Spider silk neural guidance channels (NGCs) are highly important innovations in the field of regenerative medicine. This paper will discuss the evidence in the literature that supports their function in regenerative medicine and provide a template for future experiments in the field. While many studies within the past 15 years have demonstrated the validity of spider silk as a scaffold for peripheral nerve regeneration, the molecular mechanics that facilitate regeneration are poorly understood. An emphasis on using silk from orb weaving spiders in particular may have caused researchers to overlook other spiders whose silk could prove to have vastly different …
Performance Implications Of Memory Affinity On Filesystem Caches In A Non-Uniform Memory Access Environment, Jacob Adams
Performance Implications Of Memory Affinity On Filesystem Caches In A Non-Uniform Memory Access Environment, Jacob Adams
Undergraduate Honors Theses
Non-Uniform Memory Access imposes unique challenges on every component of an operating system and the applications that run on it. One such component is the filesystem which, while not directly impacted by NUMA in most cases, typically has some form of cache whose performance is constrained by the latency and bandwidth of the memory that it is stored in. One such filesystem is ZFS, which contains its own custom caching system, known as the Adaptive Replacement Cache. This work looks at the impact of NUMA on this cache via sequential read operations, shows how current solutions intended to reduce this …
