Phased Helical Antenna Array For Cubesat Application, Kameron Lacalli

Undergraduate Honors Theses

CubeSats communication links are typically slow due to their power and size restrictions. However, a low power, high speed down link connection can allow for greater data collection and relaying, pushing the capability of 1U CubeSats beyond what is traditionally thought possible. Investigated here is the feasibility of a 11 Mb/s down link connection on a 1U CubeSat, accomplished via 2x2 helical antenna phased array operating on the 802.11 standard. Using a phased array also allows for beam steering to secure connection with the ground station when the on board ADCS may not provide precise pointing capability of the CubeSat, …

Greenland Subglacial Drainage Evolution Regulated By Weakly Connected Regions Of The Bed, Matthew J. Hoffman, Lauren C. Andrews, Stephen A. Price, Ginny A. Catania, Thomas A. Neumann, Martin P. Luthi, Jason Gulley, Claudia Ryser, Robert L. Hawley, Blaine Morris

Dartmouth Scholarship

Penetration of surface meltwater to the bed of the Greenland Ice Sheet each summer causes an initial increase in ice speed due to elevated basal water pressure, followed by slowdown in late summer that continues into fall and winter. While this seasonal pattern is commonly explained by an evolution of the subglacial drainage system from an inefficient distributed to efficient channelized configuration, mounting evidence indicates that subglacial channels are unable to explain important aspects of hydrodynamic coupling in late summer and fall. Here we use numerical models of subglacial drainage and ice flow to show that limited, gradual leakage of …

Rat Elbow Project, Wilson Roen, Spencer Lake

Mechanical Engineering and Materials Science Independent Study

Current methods for treating post-traumatic joint stiffness (PTJS), a common clinical problem following elbow surgeries which causes functional impairment of the limb, have proven insufficient.1 The main factors that expose the elbow joint to this complication are a high degree of congruence, the complexity of the joint surfaces and the high tissue sensitivity to trauma, especially the joint capsule.1 As a result, the Lake laboratory is working with elbow tissue to determine how the injury presents itself. With a deeper understanding of the injury, the lab hopes to develop more effective prevention and treatment methods for PTJS. Before the fall …

The Effects Of Rarefaction And Thermal Non-Equilibrium On A Blunt Body And A Bicone In Hypersonic Flow And Their Shape Optimization For Reducing Both Drag And Heat Transfer, Samuel Gardner, Ramesh K. Agarwal

Mechanical Engineering and Materials Science Independent Study

Design of space vehicles pose many challenging problems due to their hypersonic speeds as they need to travel through different flow regimes due to changes in the density of the atmosphere with altitude. Some of the key characteristics associated with hypersonic flow are extremely high temperatures and heat transfer to the wall of the spacecraft. At these temperatures, the assumption of thermal equilibrium is no longer valid and the effect of rotational non-equilibrium must be included in the modeling of diatomic gas flow. This thesis employs the Navier-Stokes equations, which are modified to include a rotational non-equilibrium relaxation model to …

Uncertainty Quantification (Uq) For Wall Modeled Large Eddy Simulation (Wmles) Model, Zuoxian Hou, Ramesh K. Agarwal

Mechanical Engineering and Materials Science Independent Study

In this paper non-intrusive uncertainty quantification (UQ) method is used to improve the accuracy of Smagorinsky Large eddy simulation (LES) model and a wall-modeled large eddy simulation (WMLES) model. Detailed UQ studies focusing on the closure coefficients of these two models are performed. A Polynomial Chaos (PC) surrogate model is used to evaluate the output sensitivities and uncertainties in the entire flow domain. The proposed UQ method allows for the investigation of specific flow features and phenomena within the domain. The results of the UQ analyses are then used to identify which closure coefficients in the models most influence the …

Skull Shape Affects Susceptibility To Traumatic Brain Injury, Kashyap Arcot, Guy M. Genin

Mechanical Engineering and Materials Science Independent Study

Rapid deformation of brain matter caused by skull acceleration is one of the most significant causes of concussion and severe traumatic brain injury (TBI). Despite substantial research being conducted in this area of study, very little is understood regarding the mechanics of the brain when exposed to rapid acceleration. As a result, the biomechanics of TBI remain ambiguous. In the present study, we apply a new strain estimation algorithm that enables the tracking of strains on the periphery of an image onto data obtained from tagged gel phantom and human MR-images. We use this new method to quantify strain concentrations …

Faculty Work

Recent discovery of a new class of materials, spin-gapless semiconductors (SGS), has attracted considerable attention in the last few years, primarily due to potential applications in the emerging field of spin-based electronics (spintronics). Here, we investigate structural, electronic, and magnetic properties of one potential SGS compound, MnCrVAl, using various experimental and theoretical techniques. Our calculations show that this material exhibits ≈ 0.5 eV band gap for the majority-spin states, while for the minority-spin it is nearly gapless. The calculated magnetic moment for the completely ordered structure is 2.9 µ_B/f.u., which is different from our experimentally measured value of …

Witness: Reflections On Detention In Joyce Carol Oates's Work, Tanya L. Tromble

Bearing Witness: Joyce Carol Oates Studies

Throughout her career, Joyce Carol Oates has resisted the urge of others to label her a feminist writer, insisting that she be considered a writer, independent of biological gender. As America’s “chronicler of the middle class,” she has given voice to countless invisible female character types, but this is only one concern among many. Oates is incredibly active, but rather than to actively incite, she uses her prolific pen to create testimonies to contemporary American life, seeking particularly to give voice to the voiceless among us. In spite of the notions of crime and justice being central to her fiction …

Novel Concepts In Semiconductor Disk Lasers, Zhou Yang

Optical Science and Engineering ETDs

Optically-pumped semiconductor disk lasers (SDLs) have received much attention in recent years for a myriad of applications requiring intracavity access, good beam quality, wavelength versatility, and high output powers. The traditional scheme of these lasers feature a semiconductor distributed Bragg reflector (DBR) integrated with the active region, together forming an active mirror in an external free-space cavity. The active mirror component is fabricated by either epitaxial growth or post-growth processing. This places certain restrictions on SDL design, as material system choices become limited. It further viii hinders laser performance with regard to its thermal management and laser bandwidth (tuning range). …

A Cognitive Approach To Phonology: Evidence From Signed Languages, Corrine Occhino

Linguistics ETDs

This dissertation uses corpus data from ASL and Libras (Brazilian Sign Language), to investigate the distribution of a series of static and dynamic handshapes across the two languages. While traditional phonological frameworks argue handshape distribution to be a facet of well-formedness constraints and articulatory ease (Brentari, 1998), the data analyzed here suggests that the majority of handshapes cluster around schematic form-meaning mappings. Furthermore, these schematic mappings are shown to be motivated by both language-internal and language-external construals of formal articulatory properties and embodied experiential gestalts.

Usage-based approaches to phonology (Bybee, 2001) and cognitively oriented constructional approaches (Langacker, 1987) have recognized …
