Design And Separation Mechanism On Separator For Pea Embryo Skin By Centrifugation, Dong Huanjun, Li Jiapeng, Sun Chuanzhu

Food and Machinery

A centrifugal pea embryo skin separator was designed, and its separation mechanism was also analyzed. The embryo skin did the circular motion under the action of the friction force when it entered the high-speed rotating disk and was thrown out by overcoming the friction force.Due to the different apparent density between the bean embryo and skin, the larger apparent density of the bean embryo was throwninto the outside received barrel, and the smaller apparent density of the bean skin was fallen into the inside received barrel. So chang the height of the received barrel relative to the separation disc can …

Research Of Super High Pressure Food Processing Equipment’S Synchronization Control System, Luo Wei

Food and Machinery

High pressure sterilization equipment’s strict sealing requires the synchronization system which push plug’s movement must have high synchronization accuracy. However, because of the dynamic load, friction, oil leakage, the plugeasily prone to deflection, which are greatly affecting the sealing performance. Considering about this problem, the synchronous system’s mathematical model was established. And then, the control method was also proposed: a PID control was using to the horizontal motion. And the fuzzy PID was used to control the deflection movement. The simulation results show that: the plug under this control strategy not only has a high precision horizontal motion, but also …

The Ko-Lee Key Exchange Protocol With Generalized Dihedral Groups, Christopher Lloyd

Departmental Honors & Graduate Capstone Projects

Given an arbitrary abelian group A, one may form the generalized dihedral group D(A). As D(A) is usually non-abelian, this makes it a possible candidate for use with certain non-commutative key exchange protocols. Specifically, we examine the security of using D(A) with the Ko-Lee key exchange protocol. An appropriate presentation for D(A) is developed alongside methods for computing within the group in the context of the Ko-Lee protocol. Lastly we show that for such groups Ko-Lee is susceptible to a polynomial time attack.

Synthesis Of Structurally Ordered Platinum-Iron Catalysts With Enhanced Oxygen Reduction Reaction Activity, Ye-Zheng Cai, Ming-Chuan Luo, Fang-Hui Wang, Zhao-Nan Sun, Hong Zhu

Journal of Electrochemistry

To improve oxygen reduction reaction catalytic activity of the precious metals platinum for fuel cell, the precursors of carbon-supported structurally disordered platinum-iron alloy (D-Pt₃Fe/C and D-PtFe/C) catalysts with different compositions were synthesized via a modified polyol reduction method. Then, by optimizing the annealing conditions in the inert gas, we turned the structurally disordered platinum-iron alloy to the structurally ordered platinum-iron alloy (O-Pt₃Fe/C and O-PtFe/C) catalysts. The structural characterizations of the as-prepared catalysts were performed by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and X-ray photoelectron spectroscopy (XPS). The results …

Can Nba Teams Benefit From Losing?, Ryan P. Hallisey

Honors Scholar Theses

It has been speculated that franchises in the NBA (national basketball association) lose on purpose because of the benefits that coincide with a team having a poor overall record. Teams that perform the worst are given the highest draft selections in the following season's rookie player draft, thus theoretically improving their chances of becoming a more winning team. Previous economists have used various methodology to prove that NBA teams do in fact lose on purpose; or tank. This paper builds upon this previous methodology to examine the direct impact, negative or positive, that losing on purpose has had on various …

Comparison Of Gaussian And Super Gaussian Laser Beams For Addressing Atomic Qubits, Katharina Gillen-Christandl, Glen D. Gillen, M. J. Piotrowicz, M. Saffman

Physics

We study the fidelity of single-qubit quantum gates performed with two-frequency laser fields that have a Gaussian or super Gaussian spatial mode. Numerical simulations are used to account for imperfections arising from atomic motion in an optical trap, spatially varying Stark shifts of the trapping and control beams, and transverse and axial misalignment of the control beams. Numerical results that account for the three-dimensional distribution of control light show that a super Gaussian mode with intensity I~ e^-2(r/w₀)n provides reduced sensitivity to atomic motion and beam misalignment. Choosing a super Gaussian with n = 6 …

Syntheses Of Carbon Paper Supported High-Index Faceted Pt Nanoparticles And Their Performance In Direct Formic Acid Fuel Cells, Long Huang, Mei Zhan, Yu-Cheng Wang, Yan-Fen Lin, Shuo Liu, Ting Yuan, Hui Yang, Shi-Gang Sun

Journal of Electrochemistry

Direct formic acid fuel fuels (DFAFCs) are promising energy source for portable electronic devices. Palladium (Pd) is more active than platinum (Pt) for the formic acid electrooxidation. However, the stability of Pd is much poorer than that of Pt. Unfortunately, the ultra-low natural abundance of the Pt makes it extremely expensive and limits its application as a fuel cell catalyst. Boosting both the activity and stability of Pt nanoparticles to enhance their efficiency is urgent. As previous works illustrated, nanoparticles enclosed with high-index facets usually bare a higher activity toward fuel cell related reactions than those nanoparticles with low-index facet. …

Variation In Bird Vocalizations Across A Gradient Of Traffic Noise As A Measure Of An Altered Urban Soundscape, Ryan Ernstes, John E. Quinn

Cities and the Environment (CATE)

It is evident that widespread land use and land cover change, including increasing urbanization, are altering ecological processes. One modification gaining attention is increased anthropogenic noise associated with cities. To examine potential impacts of rising anthropogenic noise, we conducted an acoustic analysis of Brown-headed Nuthatch (Sitta pusilla) and Eastern Towhee (Pipilo erythrophthalmus) vocalizations in Greenville Co., South Carolina as a function of a gradient of increasing traffic noise. Our data demonstrate that even moderate levels of noise may alter the structure of avian vocalizations. In particular, the minimum frequency of the Brown-headed Nuthatch vocalization shifted upward …

Transcending Academic Borders: A Defense Of Collaboration Between Art And Science, Laura Borkenhagen

Honors Capstone Projects

The aim of this project in its entirety was to explore different ideas about what the intersection of art and science might look like. These ideas, including my own, are presented in the following essay. In addition to the essay portion of this project, I’ve explored creative writing through poetry in attempts to immerse myself in both sides of this debate, as my academic history leans more towards the scientific realm. In the poems I’ve also tried to include bits of science through metaphorical language. The four works I have chosen to include follow the essay.
