A Toolkit For Specializing Production Operating System Code, Crispin Cowan, Dylan Mcnamee, Andrew P. Black, Calton Pu, Jonathan Walpole, Charles Krasic, Perry Wagle, Qian Zhang Jun 1997

A Toolkit For Specializing Production Operating System Code, Crispin Cowan, Dylan Mcnamee, Andrew P. Black, Calton Pu, Jonathan Walpole, Charles Krasic, Perry Wagle, Qian Zhang

Computer Science Faculty Publications and Presentations

Specialization has been recognized as a powerful technique for optimizing operating systems. However, specialization has not been broadly applied beyond the research community because the current techniques, based on manual specialization, are time-consuming and error-prone. This paper describes a specialization toolkit that should help broaden the applicability of specializing operating systems by assisting in the automatic generation of specialized code, and {\em guarding} the specialized code to ensure the specialized system continues to be correct. We demonstrate the effectiveness of the toolkit by describing experiences we have had applying it in real, production environments. We report on our experiences with …


Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers, Las Vegas Valley Water District Jun 1997

Artificial Recharge In The Las Vegas Valley: An Operational History, Michael Johnson, Erin Cole, Kay Brothers, Las Vegas Valley Water District

Publications (WR)

Artificially recharging the Las Vegas Valley (Valley) ground-water system with treated Colorado River water is one water resource management option employed by the Las Vegas Valley Water District (District) to help meet future long-term and short-term peak water demands. The District began operation of an artificial ground-water recharge program in 1988 in order to bank water for future use and to slow declining water levels. Artificial recharge occurs in the winter months, typically from October to May, when there is excess capacity in the Southern Nevada Water System (SNWS), currently a 400 Million Gallon per Day (MGD) treatment and transmission …


Optimization Considerations For Adaptive Optics Digital Imagery Systems, Robert T. Brigantic Jun 1997

Optimization Considerations For Adaptive Optics Digital Imagery Systems, Robert T. Brigantic

Theses and Dissertations

This dissertation had three objectives. The first objective was to develop image quality metrics that characterize Adaptive Optics System (AOS) performance. The second objective was to delineate control settings that maximize AOS performance. The third objective was to identify and characterize trade-offs between fully and partially compensated adaptive. For the first objective, three candidate image quality metrics were considered: the Strehl ratio, a novel metric that modifies the Strehl ratio by integrating the modulus of the average system optical transfer function to a 'noise-effective-cutoff' frequency at which some specified image spectrum signal-to-noise-ratio level is attained, and the noise-effective-cutoff frequency. It …


Effects Of Tunneling Electrons And Local Field On Nanometer Region Solid / Liquid Interfacial Reactions ——Potential Controlled Stm Induced Nanoscale Modification Of H Terminated Si(111) Surfaces, Zhaoxiong Xie, Xiongwei Cai, Caihui Shi, Bingwei Mao, Zhaowu Tian May 1997

Effects Of Tunneling Electrons And Local Field On Nanometer Region Solid / Liquid Interfacial Reactions ——Potential Controlled Stm Induced Nanoscale Modification Of H Terminated Si(111) Surfaces, Zhaoxiong Xie, Xiongwei Cai, Caihui Shi, Bingwei Mao, Zhaowu Tian

Journal of Electrochemistry

H-terminated n-Si(111) surface was found to be etched in 0.5% HF solution in nanometer scale while scanning the STM tip when the substrate potential was somehow lower than the open circuit potential at tunneling condition of Vb=+1.0 V (tip positive), It=1 nA. Much more stable Si surface was achievable at potentials much more negative than the open circuit potential (such as 500 mV negative to OCP) under the same tunneling condition. Furthermore, the etching rete at less negative potential was found to be somehow related to the tunneling current. These results indicate that the STM induced …


Studies Of Electrocatalytic Properties Of Electrode Of Dispersed Pt On Gc Support In Ethylene Glycol Oxidation, Shengpei Chen, Shigang Sun, Zhiyou Zhou, Shuanjing Hong May 1997

Studies Of Electrocatalytic Properties Of Electrode Of Dispersed Pt On Gc Support In Ethylene Glycol Oxidation, Shengpei Chen, Shigang Sun, Zhiyou Zhou, Shuanjing Hong

Journal of Electrochemistry

The structures and properties of electrocatalyst of dispersed Plutinum (Pt) on glassy carbon (GC) support under different conditions were studied using cyclic voltammetry, potential step technique, X-ray diffraction (XRD) and scanning Electron microscopy (SEM). The results indicated that after having been treated in high temperature,the dispersed Pt on GC support was recrystallised with preferented orientation, and the grain of Pt microcrystal become large and regular. It was illustrated that the dispersed Pt on GC support after high temperature treatment exhibited better stability and high activity for ethylene glycol oxidation.

Electrochemical Behavior Of Superoxide Dismutase On Gold Minigrid With Thin Layer Cell, Xiaqin Wu, Qian Liu, Bin Xu, Xiaoyun Men, Zongrang Zhang May 1997

Electrochemical Behavior Of Superoxide Dismutase On Gold Minigrid With Thin Layer Cell, Xiaqin Wu, Qian Liu, Bin Xu, Xiaoyun Men, Zongrang Zhang

Journal of Electrochemistry

The electrochemical behavior of superoxide dismutase (Cu, Zn-SOD) was investigated on gold wire electrode and gold minigrid with thin layer cell by cyclic voltammetry. A quasi reversible redox wave of SOD has obtained on gold minigrid thin layer electrode, but only oxidation peak has observed on gold wire electrode. The electrochemical reaction parameters, such as the formal potential E0′, diffusion coefficient D and standard rate constant k0′ were estimated.


Electrodeposition Of Amorphous Fe-Cr Alloy Coating, Danhong Cheng, Weiyi Xu, Yiqin Qin, Liqun Hua, Zhongyan Zhang May 1997

Electrodeposition Of Amorphous Fe-Cr Alloy Coating, Danhong Cheng, Weiyi Xu, Yiqin Qin, Liqun Hua, Zhongyan Zhang

Journal of Electrochemistry

The amorphous Fe-Cr alloy coatings were obtained by controlling the composition of bath operation conditions. It was found that the pH value, the current density and the content of chromium in Fe-Cr alloy coatings effect the amorphous structure of the coatings. The result of anodic polarization shows that the corrosion resistance of the amorphous coatings in acidic media is higher than the corrosion resistance of the crystal ones.


An Analysis On The Microstructure Of Electrodeposited Zro2-Ni Functionally Graded Materials, Chengjun Quan, Xinghua Xiang, Jingchuan Zhu, Zhongda Yin May 1997

An Analysis On The Microstructure Of Electrodeposited Zro2-Ni Functionally Graded Materials, Chengjun Quan, Xinghua Xiang, Jingchuan Zhu, Zhongda Yin

Journal of Electrochemistry

The electrodeposited ZrO2-Ni functionally graded coating was fabricated by controlling the ZrO2 concentration in the bath, and the microstructure was analyzed by X-Ray Diffraction (XRD) and Electron Probe Microanalysis (EPMA). The results show that the functionally graded coating has excellent compositional gradient distribution from the substrate to the surface. The content of ZrO2 is up to 14.4 vol% in the surface layer and the coating consists of the t-ZrO2, m-ZrO2 and Ni phases. Owing to the ZrO2 particles pressed by Ni atoms during electrodepositing, t→m transformation has occurred.
