Mechanical and Aerospace Engineering Faculty Publications

Given size and performance advantages, microchannel heat exchangers are becoming increasingly important for various energy recovery and conversion processes. In this study, detailed experimental measurements were conducted to characterize flow and heat transfer performance of a microchannel heat recovery unit (HRU) manufactured using standard photochemical etching and diffusion bonding processes. According to the global flow and temperature measurement, the HRU has delivered the predicted thermal performance under various oil and air flow rates. As expected, the heat transfer effectiveness varies between 88% and 98% for a given air and oil flow rates while it increases with air inlet temperature due …

Multi-Resonant Feedback Control Of Multiple Degree-Of-Freedom Wave Energy Converters, Ossama Abdelkhalik, Shangyan Zou, Rush D. Robinett Iii, David G. Wilson, Giorgio Bacelli, Ryan G. Coe, Umesh Korde

Michigan Tech Patents

Multi-resonant control of a 3 degree-of-freedom (heave-pitch-surge) wave energy converter enables energy capture that can be in the order of three times the energy capture of a heave-only wave energy converter. The invention uses a time domain feedback control strategy that is optimal based on the criteria of complex conjugate control. The multi-resonant control can also be used to shift the harvested energy from one of the coupled modes to another, enabling the elimination of one of the actuators otherwise required in a 3 degree-of-freedom wave energy converter. This feedback control strategy does not require wave prediction; it only requires …

Gamma-Ray Radiation Effects In Graphene-Based Transistors With H-Bn Nanometer Film Substrates, E. J. Cazalas, Michael R. Hogsed, S. R. Vangala, Michael R. Snure, John W. Mcclory

Faculty Publications

Radiation effects on graphene field effect transistors (GFETs) with hexagonal boron nitride (h-BN) thin film substrates are investigated using 60Co gamma-ray radiation. This study examines the radiation response using many samples with varying h-BN film thicknesses (1.6 and 20 nm thickness) and graphene channel lengths (5 and 10 μm). These samples were exposed to a total ionizing dose of approximately 1 Mrad(Si). I-V measurements were taken at fixed time intervals between irradiations and postirradiation. Dirac point voltage and current are extracted from the I-V measurements, as well as mobility, Dirac voltage hysteresis, and the total number of GFETs that remain …

Tracking Lysosome Migration Within Chinese Hamster Ovary (Cho) Cells Following Exposure To Nanosecond Pulsed Electric Fields, Gary L. Thompson Iii, Hope T. Beier, Bennett L. Ibey

Henry M. Rowan College of Engineering Departmental Research

Above a threshold electric field strength, 600 ns-duration pulsed electric field (nsPEF) exposure substantially porates and permeabilizes cellular plasma membranes in aqueous solution to many small ions. Repetitive exposures increase permeabilization to calcium ions (Ca²⁺) in a dosage-dependent manner. Such exposure conditions can create relatively long-lived pores that reseal after passive lateral diffusion of lipids should have closed the pores. One explanation for eventual pore resealing is active membrane repair, and an ubiquitous repair mechanism in mammalian cells is lysosome exocytosis. A previous study shows that intracellular lysosome movement halts upon a 16.2 kV/cm, 600-ns PEF exposure of …

Demonstration Of A Quasi-Cw Diode-Pumped Metastable Xenon Laser, Carl R. Sanderson, Charles W. Ballmann, Jiande Han, Amanda B. Clark, Brett H. Hokr, Kunning G. Xu, Michael C. Heaven

PRC-Affiliated Research

In this work, we present the first demonstration of a quasi-continuous-wave diode-pumped metastable xenon laser at atmospheric pressures. Lasing in metastable noble gas species has received increased attention in the last few years as a possible high-power laser source. This demonstration shows that metastable xenon has a sufficiently broad absorption spectrum to be pumped with a broad-bandwidth diode laser. This implies that a high-power metastable xenon gas laser should be achievable using high-power pump diodes.

Towards Completely Automated Glycan Synthesis, Matteo Panza

Dissertations

Carbohydrates are ubiquitous both in nature as biologically active compounds and in medicine as pharmaceuticals. Although there has been continued interest in the synthesis of carbohydrates, chemical methods require specialized knowledge and hence remain cumbersome. The need for development of rapid, efficient and operationally simple procedures has come to the fore. This dissertation focuses on the development of a fully automated platform that will enable both experts and non-specialists to perform the synthesis of glycans. Existing automated methods for the synthesis of oligosaccharides are highly sophisticated, operationally complex, and require significant user know-how. By contrast, high performance liquid chromatography (HPLC) …

Additively Manufactured Continuous Carbon Fiber Thermoplastic Composites For High-Performance Applications, Nekoda Van De Werken

Mechanical Engineering ETDs

The goal of this dissertation is to provide a foundation for the advancement of additive manufacturing (AM) toward production of high-performance carbon fiber reinforced polymer matrix composites (CFRPs). AM can provide valuable advantages over conventional composite manufacturing techniques, including the control over fiber orientation, capability of manufacturing complex geometries, out-of-autoclave processing, elimination of the need for composite tooling, and the ability to perform lights-out manufacturing. Currently, however, a suite of challenges related to modelling, design, manufacturing defects, and general limitations in the current understanding of the processing-structure-property relationships exist in AM of composites. To this end, this dissertation investigates novel …

The Catch Partner, Tyler Marr, Cindi Albrightson

Student Research

When improving a skill, the process should be as efficient as possible. Football leagues across the world have the issue when throwing without a partner, quarterbacks must use a net to catch the ball. This demands a process of throw the ball, retrieve the ball, walk back away from the net, and repeat. The time wasted in this process greatly reduces the number of throws made. Players also currently have no means of practicing catching the football without the help of another person. A football net with a passing machine would solve the issue of time and energy being wasted …

The consumption of alcohol has many effects on people, both directly and indirectly. Its no question that when most adults get together for a good time, alcohol will be involved one way or another. However, the over consumption of alcohol can lead to some of the scariest and sometimes fatal results. There are too many people that lose their lives due to drunk driving accidents, or alcohol poisoning each year. No matter how terrifying the risks are of over consuming alcohol, people are still going to go out and take their chances. But what if there were a way to …

Protective Windshield Cover, Kathryn Mcdowell, Cindi Albrightson

Student Research

A broken or cracked windshield caused by debus from strong winds and hailstorms are very common. The goal with this protective windshield cover is that the customer wouldn’t have to worry about having to replace or repair their windshield after a severe storm. It is made out of Nitrile rubber (NBR) foam, which is commonly used in yoga mats; it is very flexible and light weight. Replacing a windshield can be pretty expensive and a hassle. With this product it would make sure they had one less thing to worry about when the storms blow through.

Automatic Landing Gear, Daniel Battles, Cindi Albrightson

Student Research

Airplanes that are equipped with retractable landing gear are typically more desirable by pilots because of the benefits that come from this. There are also cons to having retractable landing gear, and having to remember to retract or extend the gear is one example. A switch on the dashboard must be flipped in order to activate the gear at the right time. In the incident that an airplane lands without the landing gear down, this is referred to as a “Gear up landing”. Gear up landings are usually caused from pilot error, which in many cases means that the pilot …

Optical Angular Scatterometry: In-Line Approach For Roll-2-Roll And Nano-Imprint Fabrication Systems, Juan Jose Faria-Briceno

Electrical and Computer Engineering ETDs

As critical dimensions continue to shrink and structures become more complex, metrology processes are challenging to implement during in-line nanomanufacturing. Non-destructive, non-contact, and high-speed conditions are required to achieve proper metrology processes during in-line manufacturing. Optical scatterometry is a nanoscale metrology tool widely used in integrated circuit manufacturing for characterization and quality control. However, most applications of optical scatterometry operate off-line. A high-speed, in-line, non-contact, non-destructive scatterometry angular system has been demonstrated in this work to scan pattern surfaces during real-time nano-fabrication.

Our system has demonstrated scanning capabilities using flat, 1D and 2D complex structures. The flat surface samples consist …

To coincide with the 2020 election season, I am currently working on an update of the project that will include a touch screen voting interface and multiple networked stations that also produce audio and video output. The interface will be housed in the same voting booths that once housed the Diebold Accuvote TS. The Diebold Accuvote TS is a screen-based voting machine that does not utilize paper as a backup. Researchers have examined …

Being Together—Or, Being Less Un-Together—With Networked Music, Rebekah Wilson, Andrew Mcmillan

Journal of Network Music and Arts

When musicians cannot travel to another location where other musicians are, they generally assume that this means they cannot perform music together—even while the technology exists to allow them to do so. The perception that Internet technology is not suited for music performance is due to a lack of exposure on navigating the limitations specific to networked music, along with the cultural belief that latency is incompatible with music performance. Many groups, however, have successfully created networked music performance systems. Such systems are particularly interesting in affording new musical and social opportunities in cases when musicians cannot travel due to …

Considering Telematic Tools For Conferences, Scott Deal, Rodney Smith, Chuiyuan Meng, Matt Vice

Journal of Network Music and Arts

Participation in conferences is an elemental component of professional life throughout the world. Two problems offset the social synergy gained from attending a far-away gathering of like-minded people. The first is the highly pronounced carbon footprint from air travel, and the second is the expense involved to participate in a conference which may be on another continent. These factors prevent many from participating who could otherwise benefit as well as contribute. As videoconferencing becomes more common and more sophisticated, it will serve as an alternative that not only benefits constituencies, but will expand the reach of a conference to more …

Understanding The Telematic Apparatus, Patrick Muller, Benjamin Burger, Joel De Giovanni, Matthias Ziegler

Journal of Network Music and Arts

Under the conditions of its geographic distribution, the “telematic performance” can be regarded as a remediation of traditional concert, theater or dance formats. Conversely, and as this paper argues, the telematic performance can also be understood as an artistic format of its own right, one which then can serve as a trope for social interaction under the conditions of critical posthumanism. To gain a wider perspective, this paper analyzes Alan Turing’s “Imitation Game” from his seminal article Computing Machinery and Intelligence, 1950, proposing it as an early conceptualization of a telematic performance. This against-the-grain reading of Turing’s text reveals certain …

Sensing Place And Presence In An Intimal Long-Distance Improvisation, Ximena Alarcon Diaz, Paul Boddie, Cagri Erdem, Eigil Aandahl, Elias Sukken Andersen, Eirik Dahl, Mari Lesteberg, Alexander Refsum Jensenius

Threadless Fire Hose Coupling, Jacob Proveaux, Cindi Albrightson

Student Research

Threading a fire hose is not a difficult task to accomplish when there is no pressure, the operator is not donned in full structure firefighting gear and the threads are still like new. However, it is difficult when these factors are applied. That’s when minutes, when seconds count. A house can be fully involved, completely engulfed by flames, in a matter of minutes. Connecting to a hydrant or connecting two hoses together with less than perfect threads is no place to waste valuable seconds while someone’s property is burning. This is where the threadless fire hose coupling concept comes in.

Robust And Self-Synchronous Steganography For Voice-Over-Ip Based On Ldpc Codes, Zhanzhan Gao, Guangming Tang, Haitao Song

Journal of System Simulation

Abstract: VoIP (Voice over IP) is a kind of voice communication technology based on UDP/IP protocols, so packet loss will inevitably happen when the channel environment deteriorates. Besides that, stego VoIP data flows are real-time and have no head or tail, which pose more challenges to accurately extract the secret messages. This paper proposes a robust and self-synchronous VoIP steganography method, which solves the above two problems under the premise of maintaining good imperceptibility. In this method, low density parity check (LDPC) codes are introduced to preprocess the secret data, and the encoded data are embedded into voice …

Transient coverage region is computed by light of view intersection and tangent searching methods. Transient coverage boundaries of different simulation times are stitched by two-dimension convex hull algorithm. Between points of the stitched region polygon edges, new vertexes are interpolated. With the method proposed, limb coverage problem and coverage fusion when time step is large can be solved. Computer simulation results show that the algorithm achieves a fine accuracy and …

Locally Weighted Learning Control For Dynamic Restricted Manipulators, Wang Gang, Tairen Sun, Shengpei Ding

Journal of System Simulation

Abstract: This paper proposes a locally weighted learning control law for a manipulator with state and input constraints and modeling uncertainties. By visualizing the control input as an extended state, the control problem is converted into control design for a state-constraint uncertain nonlinear system. Barrier Lyapunov functions are introduced into a backstepping procedure and a locally weighted learning control is designed, which ensures the exponential convergence of the barrier functions to a small neighborhood of zero and then guarantees satisfaction of system constraints and the tracking error convergence. The control feasibility and effectiveness is validated by theoretical analysis and …
