Experimental Building Demonstration Model With Viscous Fluid Dampers, Blake Thomas Reeve, Brianna Jean Kufa, Aden Malek Stepanians, Sophie Carmion Ratkovich

Architectural Engineering

The Architectural Engineering major places a heavy emphasis on structural dynamics and the role of wind and seismic loading in building analysis and design. Buildings of high importance that are critical to community function, such as hospitals, often utilize supplemental damping devices like supplemental viscous fluid dampers or base isolators to reduce the overall demands on the structural system. The design and analysis of these dampers are typically not taught at the undergraduate level, and is frequently performed by mechanical engineers, in lieu of structural engineers.

To better understand and research building behavior with supplemental damping devices, our multi-disciplinary team ...

Stabilization Of Vegetable Oil-Based Quenchants To Thermal-Oxidative Degradation: Experimental Strategy And Effect Of Oxidation On Quenching Performance, Éder Cícero Adão Simêncio, Rosa Lúcia Simêncio Otero, Lauralice De Campos Franceschini Canale, George E. Totten

Mechanical and Materials Engineering Faculty Publications and Presentations

Although petroleum oils continue to be the dominant type of basestock for the formulation of vaporizable quenchants, there is increasing pressure to identify an alternative basestock to address the limitations to their continued use because they are not a renewable basestock and they possess generally poor toxicity and biodegradability properties. Currently the most often cited alternative basestocks are those based on seed oils since they are renewable and usually non-toxic but especially because they are typically readily biodegradable. However, they suffer a critically important deficiency in that they are also typically much less stable to thermal-oxidative degradation than petroleum oils ...

Kinetics Of Length Scale Dependent Deformation Of Gold Microspheres And Micropillars, A Z M Ariful Islam 2016 The University of Western Ontario

Kinetics Of Length Scale Dependent Deformation Of Gold Microspheres And Micropillars, A Z M Ariful Islam

Electronic Thesis and Dissertation Repository

In this thesis length and time scale dependence of the operative plastic deformation mechanisms in Au is studied. Uniaxial compression tests were performed at various loading rates on FIB-milled Au micropillars and single-crystalline Au microspheres of diameter ranging from 0.8 to 6.0 µm to investigate the incipient and bulk plasticity events. Constant-load ambient-temperature creep tests were performed on the micropillars to study the time-dependent plasticity at very slow strain rates. Uniaxial compression tests were also performed on coated Au microspheres to study the effect of extrinsic constraint on the deformation mechanisms.

During uniaxial compression, both the Au micropillars ...


Measuring Frequency Availability For Cognitive Radio Networks By Means Of Adaptive Threshold, Isaac Cushman 2016 Georgia Southern University

Measuring Frequency Availability For Cognitive Radio Networks By Means Of Adaptive Threshold, Isaac Cushman

Georgia Southern University Research Symposium

Radio Frequency spectrums designated by the FCC broadcast almost all mediums of communication, in both licensed and unlicensed bands, within the United States. As technology rapidly grows however, the availability of open frequencies will quickly decrease. Our goal is to design and experimentally test a system that allows for secondary users to access frequency bands that are not currently being optimally used by the primary users and also determine the effects of mobility on the ability for a sensor to accurately find frequencies by determining an appropriate power level for communication. We set up experimental scenarios in order to test ...


Autonomous Methods In The Application Of Simple Swarm Capabilities, Joseph Watt III 2016 Georgia Southern University

Autonomous Methods In The Application Of Simple Swarm Capabilities, Joseph Watt Iii

Georgia Southern University Research Symposium

Swarm technology is a relatively new aspect to the drone industry. It involves multiple drones being able to communicate with each other and relay this back to the user. From this standpoint one operator can control all of them at once while only giving directions to one or more. This involves the use of different autonomous algorithms, similar to autopilot where programs fly the plane, that relay to one another on what adjustments to make or where to go. This idea is very useful in search and rescue operations where it might be too dangerous to insert a human. Also ...

Accelerated Insulation Recycling System (Airs), Debalina Ghosh

Georgia Southern University Research Symposium

Construction and demolition waste accounts for 52 % of the total landfilled space. While many advances in disassembly sequencing in buildings have been proposed to recycle concrete, steel, and tile associated with construction and demolition waste, the insulation contained within every building persists as a significant environmental challenge to recycle and reuse. Adding to this problem is the fact that when petroleum based foams are incinerated, it emits carbon monoxide, nitrogen oxides, isocyanine, acrylonitrile, and hydrogen cyanide in levels exceeding those allowed by the EPA, posing a significant threat to the environment and human health. Design for Disassembly (DfD) approach is ...

Effectiveness Of Soft Baseplates And Fastenings To Mitigate Track Dynamic Settlement At Transition Zone At Railway Bridge Approaches, Sakdirat Kaewunruen, A Remennikov, Akira Aikawa

Sakdirat Kaewunruen


Railway bridge approaches or bridge ends often suffer from a combination of dynamic wheel/rail interaction and poor formation compaction due to construction difficulties at the location, resulting in an initial short-wavelength track settlement at the first few sleeper bays near the bridge over a short period under revenue services. This settlement then further induces impact loading that aggravates the differential settlement, causing downtime or restricted railway operation; and importantly more frequent maintenance, which is costly and time-consuming. Principally, the stiffness transition zones can be optionally designed to either: (1) provide a gradual increase in the stiffness of ballasted track ...


A Study On The Sustainable Machining Of Titanium Alloy, Abdulhameed Alaa Dawood 2016 Western Kentucky University

A Study On The Sustainable Machining Of Titanium Alloy, Abdulhameed Alaa Dawood

Masters Theses & Specialist Projects

Titanium and its alloy (Ti-6Al-4V) are widely used in aerospace industries because of their light weight, high specific strength, and corrosion resistance. This study conducted a comparative experimental analysis of the machinability of Ti-6Al-4V for conventional flood coolant machining and sustainable dry machining. The effect of cutting speed, feed rate, and depth of cut on machining performance has been evaluated for both conditions. The machining time and surface roughness were found to be lower in dry machining compared to flood coolant machining. The tool wear was found to be unpredictable, and no significant difference was observed for dry and coolant ...
