Developing Institutional Faculty Communities To Review And Assess Sotl Work, Paul Savory, Amy Nelson Burnett, Amy M. Goodburn

Department of Industrial and Management Systems Engineering: Faculty Publications

This workshop explores theoretical questions and practical strategies for how to develop faculty peer reviewers for SOTL work. After reading a set of faculty case-study files that include varying forms of SOTL work, participants will engage in guided discussion about reviewing and assessing such work and about developing faculty communities equipped to do such work. Presenter(s) also will seek feedback on guidelines that they have developed for external reviewers of SOTL work. Many teaching efforts have focused primarily on engaging faculty to participate in SOTL initiatives, with little attention to creating mechanisms for evaluating and assessing the work resulting from …

Multi-User Uwb-Ir Systems With Interleaved Coding-Modulation On Multipath Fading Channels, Michal M. Pietrzyk, Keni Popovski, Tadeusz Wysocki, Beata J. Wysocki, Jos H. Weber

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Interleaved coding-modulation (ICM) is a recently proposed method for ultra-wideband impulse radio (UWBIR) systems. ICM exploits the concept of chip interleaving, allowing to alleviate the problem of inter-symbol and inter-pulse interference commonly present in high data rate UWB-IR systems. In this paper, we extend previous work on ICM to scarcely populated multi-user scenarios. We propose a design of a deterministic chip interleaver based on time-hopping hyperbolic congruence sequences. We also review the main parameters of the random and hyperbolic interleavers. Our results indicate that the proposed type of interleaver yields similar performance to random interleavers but with the advantage of …

Incorporation Of Polyethylene Glycol Into Self-Assembled Monolayers Enhances Substrate-Mediated Gene Delivery By Nonspecifically- Bound Complexes, Angela K. Pannier, Lonnie D Shea

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Developing systems capable of controlled and efficient gene transfer is a fundamental goal of biotechnology, with applications including functional genomics, gene therapy, and tissue engineering. Substrate-mediated delivery, also termed solid phase delivery, describes the immobilization of DNA, complexed with nonviral vectors, to a biomaterial or substrate through specific or nonspecific interactions. Cells cultured on the substrate are exposed to elevated DNA concentrations within the local microenvironment, which enhances transfection. We investigated transfection resulting from DNA complexes immobilized to a substrate through specific interactions introduced through complementary functional groups on the vector and surface or through nonspecific interactions. Self-assembled monolayers (SAMs) …

Effects Of Middle Plane Curvature On Vibrations Of A Thickness-Shear Mode Crystal Resonator, J. S. Yang, Xiaomeng Yang, Joseph A. Turner, John A. Kosinski, Robert A. Pastore, Weiping Zhang

Department of Engineering Mechanics: Faculty Publications

We study the effects of a small curvature of the middle plane of a thickness-shear mode crystal plate resonator on its vibration frequencies, modes and acceleration sensitivity. Two-dimensional equations for coupled thickness-shear, flexural and extensional vibrations of a shallow shell are used. The equations are simplified to a single equation for thickness-shear, and two equations for coupled thickness-shear and extension. Equations with different levels of coupling are used to study vibrations of rotated Y-cut quartz and langasite resonators. The influence of the middle plane curvature and coupling to extension is examined. The effect of middle plane curvature on normal acceleration …

Modeling And Simulation Of The Interaction Between Lubricant Droplets On The Slider Surface And Air Flow Within The Head/Disk Interface Of Disk Drives, Lin Wu

Department of Mechanical and Materials Engineering: Faculty Publications

The dynamic interaction phenomenon between three-dimensional (3-D) lubricant droplets located on the air bearing surface and air flow within the head-disk interface is modeled and numerically simulated. A strong interaction is observed for ultra low flying slider design. The droplet motion and deformation are able to induce non-negligible air bearing force and moment change, which in turn may impose a non-negligible disturbance on the slider’s flying attitude.

Role Of Atomic Scale Interfaces In The Compressive Behavior Of Carbon Nanotubes In Composites, S. Namilae, Namas Chandra

Department of Engineering Mechanics: Faculty Publications

Carbon nanotubes (CNT) are potentially promising fibers for ultra high strength composites. In order to fully har-ness the outstanding mechanical properties of carbon nanotubes as fiber reinforcements, it is essential to understand the nature of load transfer between fiber and matrix under various types of loading conditions that include tension, compression, torsion and a combination thereof. In this paper, we study the compressive behavior (buckling and post-buckling) of carbon nanotubes in the neat form, when they are embedded in polyethylene matrix and with in¬terface chemical modifications using molecular dynamics simulations based on Tersoff–Brenner potential. It is ob¬served that the critical …

Optical Emission In Magnetically Confined Laser-Induced Breakdown Spectroscopy, X. K. Shen, Yongfeng Lu, T. Gebre, Hao Ling, Y. X. Han

Department of Electrical and Computer Engineering: Faculty Publications

Magnetically confined laser-induced breakdown spectroscopy was investigated by studying the optical emission from laser-induced plasma plumes expanding across an external transverse magnetic field. KrF excimer laser pulses with a pulse duration of 23 ns and a wavelength of 248 nm were used to produce plasmas from Al, Cu, and Co targets. Various optical emission lines obtained from Al and Cu targets show an obvious enhancement in the intensity of optical emission when a magnetic field of ~0.8 T is applied, while the optical emission lines from Co targets show a decrease in the optical emission intensity. The enhancement factors of …

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

This paper is a summary of what is known scientifically about the closure of earthen manure structures without artificial liners, including lagoons, storage basins, and runoff holding ponds, and what needs to be examined further to increase our understanding of the dynamics of closing them in an environmentally safe manner. This information should be useful as a guide for state regulatory agencies considering rules for closure and for academicians and consultants who work with livestock production facilities.

Load Transfer Issues In The Tensile And Compressive Behavior Of Multiwall Carbon Nanotubes, G. A. Shen, S. Namilae, Namas Chandra

Department of Mechanical and Materials Engineering: Faculty Publications

Carbon nanotubes (CNT) are considered to be ultra strong and stiff reinforcements for structural composite applications. The load transfer between the inner and outer nanotubes in multiwall carbon nanotubes (MWCNT) has to be clearly understood to realize their potential in not only composites, but also other applications such as nano-springs and nano-bearings. In this paper, we study the load transfer between the walls of multiwall nanotubes both in tension and compression using molecular dynamics simulations. It is found that very minimal load is transferred to the inner nanotube during tension. The load transfer in compression of capped nanotubes is much …

Vegetative Treatment Systems For Open Lot Runoff: Review Of Literature, Richard K. Koelsch, Jeffrey Lorimer, Kyle Mankin

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Runoff from open lot livestock systems (beef and dairy) defined as Concentrated Animal Feeding Operations (CAFO) must be controlled by systems designed and managed to prevent the release of manure-contaminated runoff for storms equal to or less than a 25-year, 24-hour design storm. This performance standard has been attained for open lot systems with some combination of clean water diversion, settling basins, runoff collection ponds and irrigation systems (baseline system).

An alternative approach is to rely on overland flow and infiltration into cropland with perennial forage or grasses for treatment of open lot runoff. Such vegetative systems have been researched …

“Strategically Locating Soybean And Biodiesel Processing Facilities In Nebraska”, Lori Luebbe

Industrial Agricultural Products Center: Publications and Information

Is the production of biodiesel feasible in Nebraska? A standard answer depends on the business operating condition. More specifically, a statewide, as opposed to a site specific, study conducted by the Independent Biodiesel Feasibility Group (IBFG) in July 2005 for the Nebraska Soybean Association (NSA) concluded a positive return on equity could be expected. At that time, the return was estimated to be poor for the small scale, 5 million gallons per year (MGPY) scenario analyzed and only modest for the mid, 15 MGPY, and larger scale, 30 MGPY scenarios. For a complete copy of the feasibility study, contact the …

Yield Response Of Corn To Deficit Irrigation In A Semiarid Climate, José O. Payero, Steven R. Melvin, Suat Irmak, David D. Tarkalson

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Irrigation water supplies are decreasing in many areas of the U.S. Great Plains, which is requiring many farmers to con¬sider deficit-irrigating corn (Zea mays L.) or growing crops like winter wheat (Triticum aestivum L.) that require less water, but that are less profitable. The objectives of this study were to: (1) quantify the yield response of corn to deficit irrigation, and (2) determine which of several seasonal water variables correlated best to corn yield in a semiarid climate. Eight (T1–T8) and nine (T1–T9) deficit-irrigated treatments (including dryland), were compared in 2003 and 2004 in North Platte, Nebraska. The …
