If You Think Education Is Expensive, Try Ignorance., Aldemaro Romero Jr.

Publications and Research

This is the 100th column of this series. During

the two years during which this column has been

published uninterruptedly on a weekly basis, a

common question I received is why do I defend

higher education?

I remember when I decided to become a scientist.

The day was October 5, 1957. I was a 6-year-old kid

living in Venezuela. The big headline in the newspaper

that day was that the Soviets had launched

an artificial satellite named Sputnik. I was amazed.

I asked my father all kinds of questions about it,

but he could not tell me much more than …

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 …

An Exploratory Study On The Possible Effect Of Hydraulic Fracturing Activities On Air Quality In The Eagle Ford Shale Region Of Texas., Laura B. Fimibama

Electronic Theses and Dissertations

Eagle Ford Shale (EFS) play is one out of five major oil and gas formations in Texas, found in the South-Eastern region with approximately 30 counties. In addition to natural gas, it produces crude oil and petroleum liquids which in recent times has resulted in a surge in drilling due to a new drilling technology – hydraulic fracturing that injects massive quantities of water along with sand and chemical additives into a well to create tiny hairline cracks in rock formations. The success of this technology has made gas extraction more economically feasible. However, this technique has generated an array …

Promises Fulfilled? A Systematic Review Of The Impacts Of Promise Programs, Elise Swanson, Angela Watson, Gary W. Ritter, Malachi Nichols

Education Reform Faculty and Graduate Students Publications

This review examines the existing evidence on the impacts of Promise Programs on community development, K-12 academic achievement, and student postsecondary outcomes. Promise Programs are place-based, guaranteed college scholarships offered to all students who graduate from a certain school or district while meeting the minimum thresholds of the program. We delineate Promise Programs by their design - whether the scholarships are available to all students, are awarded based on merit, or are awarded based on need. We also note the applicability of Promise Programs - whether the funds be used at a wide range of postsecondary institutions, or if they …

Design And Realization Of A Nonlinear Vibration Energy Harvester For Cost Effective Additive Manufacturing, Rodrigo Barriuso De Juan

Masters Theses

Environmental energy harvesting has always been an attractive solution to the search for sustainable energy sources. Combined with the miniaturization and power consumption reduction of sensors and portable electronic devices, the possibility of powering using environmental energy, like vibration energy, instead of conventional batteries increases exponentially. Vibrational energy harvesting can be achieved using devices based on different physical phenomena. Electromagnetic based devices seem to be among the most effective when considering the power output levels within low frequency applications. However, these devices have always had inherent challenges including size and manufacturing cost reduction as well as limitations on the range …

Integrative Analysis Of Heterogeneous Genomics Data For Triple Negative Breast Cancer And High Grade Serous Ovarian Cancer, Abdelrahman Hosny Ibrahim

Master's Theses

The human body is made up of trillions of cells. Although all the human body cells contain the same DNA sequence inside their nuclei, each one carries out its own function. Normally, human cells grow and divide to form daughter cells as the body needs them. When cells grow old, or lose their ability to function properly, they die (in a very organized way called apoptosis or programmed cell death) and new cells take their role. Cancer is a disease that is caused by uncontrolled division of abnormal cells in some part of the body, breaking the natural process of …

Change In Urban Fabric Through Space And Time At Differing Levels Of Automobility, Kristin A. Floberg

Master's Theses

For thousands of years cities have been centers for commerce, creativity, and livelihood, consisting of relatively unchanged characteristics such as walkable streets, diverse land-uses, and human-scaled buildings and streets. With the introduction of the automobile, this past century the desire for free-flowing traffic and convenient parking has drastically transformed the fabric of many cities. Transforming cities into places that accommodate automobiles has transformed downtowns into office parks rather than vibrant mixed-use environments and destroyed communities.

Investigation into reducing automobiles in cities has increasingly piqued the interest of stakeholders in the environmental, safety and economic development communities. This body of research …

This research was conducted to develop and qualify a vacuum GaAs semiconductor monolithic microwave integrated circuit die attach process. Research was done to understand the causes and effects of voiding levels on device performance and reliability. Simultaneous investigation was done to qualify vacuum-attach as a successful methodology by which minimal voiding levels were achieved. After an initial vacuum-attach trial was completed to verify the methodology, internal accept/reject criteria were developed to qualify die attach interfaces. A dual phase attachment methodology was created to minimize tolerance stacking resulting in more consistent component placement. MATLAB image processing code was developed to quantify …

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). …
