Fire Protection And Life Safety Analysis Of Christopher Cohan Center, Kristen Dentici

Fire Protection Engineering: Culminating Experience Project Reports

This report analyzes the fire protection and life safety systems of the Christopher Cohan Center. The building was assessed from both a prescriptive and performance-based approach.

The prescriptive design analyzed the code requirements for the building based on the 2018 IBC, with some consideration for the codes in place at the time of construction. The prescriptive analysis main focus was on egress systems, fire alarm and detection, fire suppression, and structural fire protection. The egress analysis found that the exits and exit configuration were sufficient for the occupant loads that were calculated for the building. The fire alarm and detection …

Lifecycle Reactive Transport Modeling For Assessing Integrity In Offshore Energy Systems, Temitope Ayokunle Ajayi

LSU Doctoral Dissertations

Subsurface leaks and spills are a matter of significant concern to the oil and gas industry because of their impact on health, safety and environment. It is thus important to study and assess the integrity of our energy systems and the physico-chemical processes that affect them.

To avoid leakage of fluids from wellbores, barrier materials are used for sealing formation fluids and creating a single flow path through the well. These barrier materials are constantly subjected to subsurface fluid fluxes and temperature, pressure and chemical conditions over the extended periods the wells remain underground. This makes it imperative to assess …

Optical Microresonator-Based Flow-Speed Sensor, Elie Ramon Salameh

Mechanical Engineering Research Theses and Dissertations

Optical sensors have become more prominent in atmospheric measurement systems, with LiDAR instruments deployed on a variety of earth-bound, air-borne, and space-based platforms. In recent years, the interest in the human exploration of Mars has created a substantial push towards reliable and compact sensing elements for Mars exploration missions, particularly during a spacecraft’s entry, descent, and landing stages. Real-time sensors able to reliably measure the craft’s speed relative to the surrounding atmosphere during these stages are thus of great interest. In this dissertation, a proof-of-concept for an optical microfabricated sensor, which leverages the whispering-gallery-mode (WGM) and Doppler shift principles, is …

Examination Of Ionization In Cesium Diode Pumped Alkali Lasers With An Ion Chamber Diagnostic, Benjamin Oliker

Optical Science and Engineering ETDs

Diode pumped alkali lasers (DPALs) are leading candidates for future high power applications, with many potential utilities for the military, aerospace, communications, and scientific diagnostics. A critical step in their development is measurement and understanding of unwanted ionization processes that occur inside the laser, which decrease efficiency, reduce the usable alkali population, and increase heat load. In this dissertation, direct measurement of the ionization rate of a cesium DPAL gain medium are made for the first time, via application of an ion chamber diagnostic. Results will demonstrate that the rate of ionization is slow compared to pump absorption, with a …

The Take It All Tailgate Wagon: From Concept Through Prototype Development, Carly Huguley

Honors Theses

This text outlines the design process of the Take it All Tailgate from concept design through two prototyping stages. The Take it All Tailgate was designed for the every gameday tailgater who has a lot of tailgating equipment to haul from their vehicle to the tailgating area. With this in mind, a team of five members designed a wheeled storage space that also acts as a table in the tailgating area. Lean manufacturing was implemented to improve the build process and the overall design of the storage wagon.

The Environmental And Nutritional Dilemma Of Beef Production And Consumption, Hannah A. Swilling, Stefano De Rosmini, Brooke Lovan

Chemical Engineering Undergraduate Honors Theses

Based on previous studies, it has been stated that beef production and consumption in the United States is detrimental to the environment. However, in depth studies analyzing the change of beef production and consumption, the environmental impacts, the external costs, the lifestyle implications as well as the nutritional, the social and the cultural aspects of beef have not been conducted. The goal of this study is to analyze the multiple aspects of the dilemma over beef production and consumption. This was done through an analysis of beef production and consumption data over the past 60 years to determine how it …

Intelligibility Of Medically Related Sentences In Quiet, Speech-Shaped Noise, And Hospital Noise, Tessa Bent, Melissa Baese-Berk, Erica E. Ryherd, Sidney Perry

Durham School of Architectural Engineering and Construction: Faculty Publications

Noise in healthcare settings, such as hospitals, often exceeds levels recommended by health organizations. Although researchers and medical professionals have raised concerns about the effect of these noise levels on spoken communication, objective measures of behavioral intelligibility in hospital noise are lacking. Further, no studies of intelligibility in hospital noise used medically relevant terminology, which may differentially impact intelligibility compared to standard terminology in speech perception research and is essential for ensuring ecological validity. Here, intelligibility was measured using online testing for 69 young adult listeners in three listening conditions (i.e., quiet, speech-shaped noise, and hospital noise: 23 listeners per …

3 Stem Projects By Fares Soliman, Fares Soliman

STEM Month

My name is Fares Soliman. I am a fourth grade student from John Hill School Boonton NJ. I created a 3 STEM project. The first project that I made was a doll. I used pink yarn for the dress and brown yarn for the hair. I also used a round wooden ball for the face. The second project that I created was a diorama of a farm. I put some grass, trees, a barn, hay sticks, some animals, a bridge, a fence, some plastic food and corn for the crop. My third project was a diorama of a park. It …

Students Interest And Thoughts On Stem, Chrisitine Girtain

STEM Month

I am Juan Sebastian Bohorquez Mora, I am a sophomore student at Toms River High School North. I am interested in biofuels because I believe they are a good option to replace fossil fuels. I am also interested in duckweed because biofuels are made out of crops, and people need to eat those crops. That’s when duckweed comes in and it can be used as a feedstock for ethanol production which is a biofuel. Bioethanol is a type of biofuel and it is derived from the corn’s starch. Instead of making ethanol from the corn’s starch, we can use duckweed …

360 Sounds: Drum Sample Packs With Supporting Video Series And Website, Maddie M. Harmon

Honors Scholars Collaborative Projects

Drums are the foundation of any piece of music; because of this, it is impossible to create even a decent mix of a song without first taking the time to really mold and sculpt drum sounds. This is a painstaking process that includes extreme attention to detail in every aspect—selecting and placing microphones, tuning the drum kit, guiding the drummer to play in the pocket, adding effects processing, editing the drum tracks into single-hit takes after recording. Oftentimes (especially in the more commonplace lower-budget sessions that often don’t have the finances to spend an adequate amount of time perfecting drum …
