Momentum, Summer 2018
(Virginia Tech, 2018)
Momentum is the quarterly magazine of the Department of Mechanical Engineering at Virginia Tech.
Relationship between Organic Carbon and Opportunistic Pathogens in Simulated Glass Water Heaters
Controlling organic carbon levels in municipal water has been hypothesized to limit downstream growth of bacteria and opportunistic pathogens in premise plumbing (OPPPs). Here, the relationships between influent organic ...
Evaluation of Resiliency of Transportation Networks After Disasters
(The National Academies of Sciences, Engineering, and Medicine, 2012)
The resiliency of infrastructure, particularly as related to transportation networks, is essential to any society. This resiliency is especially vital in the aftermath of disasters. Recent events around the globe, including ...
Zro2 Thin-Film-Based Sapphire Fiber Temperature Sensor
(Optical Society of America, 2012-10-01)
A submicrometer-thick zirconium dioxide film was deposited on the tip of a polished C-plane sapphire fiber to fabricate a temperature sensor that can work to an extended temperature range. Zirconium dioxide was selected ...
Evidence for anisotropic polar nanoregions in relaxor Pb(Mg1/3Nb2/3)O-3: A neutron study of the elastic constants and anomalous TA phonon damping in PMN
(American Physical Society, 2012-09-18)
We use neutron inelastic scattering to characterize the acoustic phonons in the relaxor Pb(Mg1/3Nb2/3)O-3 (PMN) and demonstrate the presence of a highly anisotropic damping mechanism that is directly related to short-range ...
Multi-dimensional characterization of electrostatic surface potential computation on graphics processors
Background Calculating the electrostatic surface potential (ESP) of a biomolecule is critical towards understanding biomolecular function. Because of its quadratic computational complexity (as a function of the number of ...
Network-based functional enrichment
Background Many methods have been developed to infer and reason about molecular interaction networks. These approaches often yield networks with hundreds or thousands of nodes and up to an order of magnitude more edges. ...
Understanding Application Behaviours for Android Security: A Systematic Characterization
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2016), TR-16-05
In contrast to most existing research on Android focusing on specific security issues, there is little broad understanding of Android application run-time characteristics and their security implications. To mitigate this ...
Missing genes in the annotation of prokaryotic genomes
Background Protein-coding gene detection in prokaryotic genomes is considered a much simpler problem than in intron-containing eukaryotic genomes. However there have been reports that prokaryotic gene finder programs have ...
Quantitative prediction of the effect of genetic variation using hidden Markov models
Background With the development of sequencing technologies, more and more sequence variants are available for investigation. Different classes of variants in the human genome have been identified, including single nucleotide ...
