Storwatts: Compressed Air Energy Storage System, Michael Biederer, John O'Malley Iii, Joseph Burke, Matthew Komo Jun 2012

Storwatts: Compressed Air Energy Storage System, Michael Biederer, John O'Malley Iii, Joseph Burke, Matthew Komo

Mechanical Engineering Senior Theses

The current problem with energy backup and grid stabilization systems is that both either require fuel and constant maintenance, such as diesel generators, or cannot perform at their peak operation and need constant replacement, like batteries. Our solution and the goal of the StorWatts senior design project was to design and create a small-scale compressed air energy storage system to be used in place of traditional energy backup and grid stabilization systems. The StorWatts system does not need fuel in order to store and generate power and therefore does not require constant refueling and maintenance. It also can work in …

Common-Path Endoscopic Optical Coherence Tomography Application To Human Internal Organs Detection, Yanjun Li, Yinan Zhang, Xinwei Lan, Hai Xiao Jun 2012

Common-Path Endoscopic Optical Coherence Tomography Application To Human Internal Organs Detection, Yanjun Li, Yinan Zhang, Xinwei Lan, Hai Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

Due to the small volume of incipient Pathological Cells, the conventional imaging methods cannot effectively diagnose early-stage cytopathic effect. Since the spatial resolution of optical coherence tomography (OCT) can reach the magnitude of micron, and if OCT probe possesses the characteristic of small fabric and nice flexibility in order to easily enter human body, OCT probe can detect the cytopathic effect in a very early-stage. So, this article first introduces some existent common-path OCT system and then compares the advantages and the disadvantages of each CP-EOCT. Finally, this article mainly researches on a new common-path Endoscopic OCT (CP-EOCT) which possesses …


Chemical Potential Perturbation: A Method To Predict Chemical Potential Using Molecular Simulations, Stan G. Moore Jun 2012

Chemical Potential Perturbation: A Method To Predict Chemical Potential Using Molecular Simulations, Stan G. Moore

Theses and Dissertations

A new method, called chemical potential perturbation (CPP), has been developed to predict the chemical potential as a function of composition in molecular simulations. The CPP method applies a spatially varying external potential to the simulation, causing the composition to depend upon position in the simulation cell. Following equilibration, the homogeneous chemical potential as a function of composition can be determined relative to some reference state after correcting for the effects of the inhomogeneity of the system. The CPP method allows one to predict chemical potential for a wide range of composition points using a single simulation and works for …


Traffic Signal Optimization Using Ant Colony Algorithm, David Renfrew, Xiao-Hua Yu Jun 2012

Traffic Signal Optimization Using Ant Colony Algorithm, David Renfrew, Xiao-Hua Yu

Electrical Engineering

Traffic signal control is an effective way to improve the efficiency of traffic networks and reduce users’ delays. Ant Colony Optimization (ACO) is a meta-heuristic algorithm based on the behavior of ant colonies searching for food. ACO has successfully been employed to solve many complicated combinatorial optimization problems and its stochastic and decentralized nature fits well with traffic networks. This research investigates the application of the ant colony algorithm to minimize user delay at traffic intersections. Various ACO algorithms are discussed and a rolling horizon approach is also employed to achieve real-time adaptive control. Computer simulation results show that this …

Enabling Green Networking With A Power Down Approach, Brendan Mumey, Jian Tang, Saiichi Hashimoto Jun 2012

Enabling Green Networking With A Power Down Approach, Brendan Mumey, Jian Tang, Saiichi Hashimoto

Electrical Engineering and Computer Science - All Scholarship

The most straightforward way to reduce network power consumption is to turn off idle links and nodes (switches/routers), which we call the power down approach. In a wired network, especially in a backbone network, many links are actually “bundles” of multiple physical cables and line cards that can be shut down independently. In this paper, we study the following routing problem for green networking in wired networks: Given a set of end-to-end communication sessions, determine how to route data traffic through the network such that total power consumption is minimized by turning off unused cables in bundled links and nodes, …


Interfacial Friction Between Semiflexible Polymers And Crystalline Surfaces, Nikolai V. Priezjev Jun 2012

Interfacial Friction Between Semiflexible Polymers And Crystalline Surfaces, Nikolai V. Priezjev

Mechanical and Materials Engineering Faculty Publications

The results obtained from molecular dynamics simulations of the friction at an interface between polymer melts and weakly attractive crystalline surfaces are reported. We consider a coarse-grained bead-spring model of linear chains with adjustable intrinsic stiffness. The structure and relaxation dynamics of polymer chains near interfaces are quantified by the radius of gyration and decay of the time autocorrelation function of the first normal mode. We found that the friction coefficient at small slip velocities exhibits a distinct maximum which appears due to shear-induced alignment of semiflexible chain segments in contact with solid walls. At large slip velocities, the friction …

Orbital Angular Momentum In Four Channel Spatial Domain Multiplexing System For Multi-Terabit Per Second Communication Architectures, Syed H. Murshid, Hari Priya Muralikrishnan, Samuel Peter Kozaitis

Electrical Engineering and Computer Science Faculty Publications

Bandwidth increase has always been an important area of research in communications. A novel multiplexing technique known as Spatial Domain Multiplexing (SDM) has been developed at the Optronics Laboratory of Florida Institute of Technology to increase the bandwidth to T-bits/s range. In this technique, space inside the fiber is used effectively to transmit up to four channels of same wavelength at the same time. Experimental and theoretical analysis shows that these channels follow independent helical paths inside the fiber without interfering with each other. Multiple pigtail laser sources of exactly the same wavelength are used to launch light into a …

This study uses data from the Tar-River Basin in North Carolina to explore how space-time rainfall variability influences the hydrologic response from observational and modeling perspectives. For understanding the basin scale effect, the Tar-River Basin is divided into four cascade sub-basins ranging from 1106 km2 up to 5654 km2. The study evaluates the catchments’ response to rainfall for a large number of storm events by computing the event runoff coefficient based on streamflow observations and through simulations from a semi-distributed hydrological model. Comparison of observed to simulated hydrographs from the hydrological model shows that distributed rainfall forcing …


Evaluation Of Advanced Conductive Nickel Materials For Strain Sensing In Carbon Fiber Reinforced Polymers, Michael Christian Koecher Jun 2012

Evaluation Of Advanced Conductive Nickel Materials For Strain Sensing In Carbon Fiber Reinforced Polymers, Michael Christian Koecher

Theses and Dissertations

Due to their unique properties, carbon fiber reinforced polymers (CFRP) are becoming ever more prevalent in today's society. Unfortunately, CFRP suffer from a wide range of failure modes and structural health monitoring methods are currently insufficient to predict these failures. It is apparent that self-sensing structural health monitoring could be advantageous to protect consumers from catastrophic failure in CFRP structures. Previous research has shown that embedded nickel nanostrand nanocomposites can be used to instantaneously measure strain in carbon fiber composites, but these methods have been severely limited and can induce high stress concentrations that compromise the structural integrity of the …

Mathematical Modeling And Experimental Analysis Of Multiple Channel Orbital Angular Momentum In Spatial Domain Multiplexing, Syed H. Murshid, Hari Priya Muralikrishnan, Samuel Peter Kozaitis

Electrical Engineering and Computer Science Faculty Publications

A novel multiplexing technique known as Spatial Domain multiplexing (SDM) has been developed in recent years and offers many advantages over its counterparts. With multiple channel transmission of the same wavelength over a single multimode carrier fiber, SDM increases the data capacity by multiple folds. Input channels are launched at appropriate input angles to produce skew ray propagation. The output of the system when projected on a screen is observed as concentric rings. These SDM beams carry orbital angular momentum. Experiments show that two input sources with the same launch conditions, but opposite topological charge take different helical paths inside …

Concentration Effects And Ion Properties Controlling The Fractionation Of Halides During Aerosol Formation, Marcelo I. Guzman, Richa R. Athalye, Jose M. Rodriguez

Chemistry Faculty Publications

During the aerosolization process at the sea surface, halides are incorporated into aerosol droplets, where they may play an important role in tropospheric ozone chemistry. Although this process may significantly contribute to the formation of reactive gas phase molecular halogens, little is known about the environmental factors that control how halides selectively accumulate at the air-water interface. In this study, the production of sea spray aerosol is simulated using electrospray ionization (ESI) of 100 nM equimolar solutions of NaCl, NaBr, NaI, NaNO(2), NaNO(3), NaClO(4), and NaIO(4). The microdroplets generated are analyzed by mass spectrometry to study the comparative enrichment of …

Agenda: A Low-Carbon Energy Blueprint For The American West, University Of Colorado Boulder. Natural Resources Law Center, University Of Colorado Boulder. Renewable And Sustainable Energy Institute, Western Resource Advocates, Rocky Mountain Research Station (Fort Collins, Colo.)

A Low-Carbon Energy Blueprint for the American West (Martz Summer Conference, June 6-8)

The future of the planet may depend upon our ability to increase energy supplies even as we reduce carbon emissions. This conference will address how a low-carbon energy program might evolve with a particular focus on the American West. It will focus on the future of energy in the West--on a “managed transition” to a different energy mix, on the need to nest this effort in a framework that acknowledges interconnections, and on identifying the most salient opportunities to consider the legal, political, financial, and technical challenges.
