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 2016 Georgia Southern University

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 2016 University of Wollongong

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 ...

Dose Dependence Of Radiation Damage In Nano-Structured Amorphous Sioc/Crystalline Fe Composite, Qing Su, Lloyd Price, Lin Shao, Michael Nastasi 2016 University of Nebraska-Lincoln

Dose Dependence Of Radiation Damage In Nano-Structured Amorphous Sioc/Crystalline Fe Composite, Qing Su, Lloyd Price, Lin Shao, Michael Nastasi

Mechanical & Materials Engineering Faculty Publications

Through examination of radiation tolerance properties of amorphous silicon oxycarbide (SiOC) and crystalline Fe composite to averaged damage levels, from approximately 8 to 30 displacements per atom (dpa), we demonstrated that the Fe/SiOC interface and the Fe/amorphous FexSiyOz interface act as efficient defect sinks and promote the recombination of vacancies and interstitials. For thick Fe/SiOC multilayers, a clear Fe/SiOC interface remained and no irradiation-induced mixing was observed even after 32 dpa. For thin Fe/SiOC multilayers, an amorphous FexSiyOz intermixed layer was observed to form at ...

Turning An Organic Semiconductor Into A Low-Resistance Material By Ion Implantation, Beatrice Fraboni, Alessandra Scidà, Piero Cosseddu, Yongqiang Wang, Michael Nastasi, Silvia Milita, Annalisa Bonfiglio

NCESR Publications and Research

We report on the effects of low energy ion implantation on thin films of pentacene, carried out to investigate the efficacy of this process in the fabrication of organic electronic devices. Two different ions, Ne and N, have been implanted and compared, to assess the effects of different reactivity within the hydrocarbon matrix. Strong modification of the electrical conductivity, stable in time, is observed following ion implantation. This effect is significantly larger for N implants (up to six orders of magnitude), which are shown to introduce stable charged species within the hydrocarbon matrix, not only damage as is the case ...
