A Quantum Test Algorithm, Marek Perkowski, Jacob Biamonte Jan 2005

A Quantum Test Algorithm, Marek Perkowski, Jacob Biamonte

Electrical and Computer Engineering Faculty Publications and Presentations

Current processes validation methods rely on diverse input states and exponential applications of state tomography. Through generalization of classical test theory exceptions to this rule are found. Instead of expanding a complete operator basis to validate a process, the objective is to utilize quantum effects making each gate realized in the process act on a complete set of characteristic states and next extract functional information. Random noise, systematic errors, initialization inaccuracies and measurement faults must also be detected. This concept is applied to the switching class comprising the search oracle. In a first approach, the test set cardinality is held …

Realizing Ternary Quantum Switching Networks Without Ancilla Bits, Marek Perkowski, Guowu Yang, Xiaoyu Song, Jinzhao Wu Jan 2005

Realizing Ternary Quantum Switching Networks Without Ancilla Bits, Marek Perkowski, Guowu Yang, Xiaoyu Song, Jinzhao Wu

Electrical and Computer Engineering Faculty Publications and Presentations

This paper investigates the synthesis of quantum networks built to realize ternary switching circuits in the absence of ancilla bits. The results we established are twofold. The first shows that ternary Swap, ternary NOT and ternary Toffoli gates are universal for the realization of arbitrary n × n ternary quantum switching networks without ancilla bits. The second result proves that all n×n quantum ternary networks can be generated by NOT, Controlled-NOT, Multiply-Two and Toffoli gates. Our approach is constructive.

Biotic Resistance To Invasion: Native Predator Limits Abundance And Distribution Of An Introduced Crab, Catherine E. De Rivera, Greg M. Ruiz, Anson Hines, Paul Jivoff Jan 2005

Biotic Resistance To Invasion: Native Predator Limits Abundance And Distribution Of An Introduced Crab, Catherine E. De Rivera, Greg M. Ruiz, Anson Hines, Paul Jivoff

Environmental Science and Management Faculty Publications and Presentations

Introduced species frequently escape the natural enemies (predators, competitors, and parasites) that limit their distribution and abundance in the native range. This reduction in native predators, competitors, and parasites may result in ecological release in the introduced range. However, biological interactions also can limit the establishment and spread of nonnative populations. The extent to which such biotic resistance occurs is poorly resolved, especially for marine ecosystems. Here we test whether a native predator, the blue crab Callinectes sapidus, affects the abundance and geographic range of the introduced European green crab Carcinus maenas in eastern North America. Both crab species …

Nonindigenous species have caused substantial environmental and economic damage to coastal areas. Moreover, the extent and impacts of nonindigenous species are increasing over time. To develop predictive models and to identify which areas should be targeted for impact mitigation or early detection, we need a basic foundation of knowledge about the spatial and temporal patterns of invasions. This project was developed because we lacked the necessary data to rigorously evaluate the patterns of coastal invasions. This collaborative project, between the Smithsonian Environmental Research Center, the National Estuarine Research Reserve System (NERRS) and the National Marine Sanctuary Program (NMSP), established a …

Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner Jan 2005

Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner

Environmental Science and Management Faculty Publications and Presentations

Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and physiology of species important to this ecosystem. Since the response of plants to elevated CO2 may be limited by environmental factors, soil temperature was also examined to determine if low soil temperatures limit CO2 response. To determine how CO2 and soil temperature affect the growth of species native to the sagebrush steppe, bottlebrush squirreltail [Elymus elymoides (Raf.) Swezey], Thurber needlegrass (Stipa thurberiana Piper), …

Temporal Variation In Nutrient Uptake Capacity By Intact Roots Of Mature Loblolly Pine, Melissa S. Lucash, J. Devereux Joslin, Ruth D. Yanai

Environmental Science and Management Faculty Publications and Presentations

Nutrient uptake is generally thought to exhibit a simple seasonal pattern, but few studies have measured temporal variation of nutrient uptake capacity in mature trees. We measured net uptake capacity of K, NH+ 4, NO 3 −, Mg and Ca across a range of solution concentrations by roots of mature loblolly pine at Calhoun Experimental Forest in October 2001, July 2001, and April 2002. Uptake capacity was generally lowest in July; rates in October were similar to those in April. Across a range of concentrations, antecedent nutrient solution concentrations affected the temporal patterns in uptake in July but not in …

Depth-Shifting Of Shallow Water Guide Source Observations, Lisa M. Zurk, Brian H. Tracey Jan 2005

Depth-Shifting Of Shallow Water Guide Source Observations, Lisa M. Zurk, Brian H. Tracey

Electrical and Computer Engineering Faculty Publications and Presentations

In theory, matched field processing offers the significant benefit of higher signal gains and increased localization capability. However, this has not been robustly observed in practice because of inherent uncertainties about details of the shallow water propagation environments which limit the prediction of the channel response. The use of guide sources to directly measure the transfer function between source and receiver arrays has been proposed as a means for reducing mismatch. However, the guide source measurement only provides a measured transfer function at the guide source location. In this paper a method of depth-shifting guide source observations is proposed, making …

Adhesion Of Copper To Poly(Tetrafluoroethylene) And Fluorinated Ethylene Propylene Copolymer Surfaces Modified With Vacuum Uv Radiation From Helium Arc Plasma, Zheng Sun

Theses

Teflon materials including poly(tetrafluoroethylene) (PTFE) and poly (tetrafluoroethylene-co-hexafluoropropylene) (FEP) were exposed to vacuum UV (VUV) radiation from a He DC arc plasma that was made to rotate inside of a graphite tube by the application of an auxiliary magnetic field. The polymer films were covered with optical filters having different cut-off wavelengths to vary the spectrum of the VUV radiation that modified the fluoropolymer surface. The properties of the surface changed after surface modification as follows: (1) water contact angles started to decrease in the wavelength region between 173 and 160 nm and continued to decrease with shorter wavelengths; (2) …

Utilizing Neural Networks To Proactively Monitor Energy Usage In City Of Rochester Buildings, Brian J. Gillis Jan 2005

Utilizing Neural Networks To Proactively Monitor Energy Usage In City Of Rochester Buildings, Brian J. Gillis

Theses

Energy usage within buildings in the United States is a very important topic because of the current price of natural gas, steam, and electricity and the ever-increasing depletion of fossil fuels. Therefore, it is necessary to carefully analyze building energy consumption. Currently, there are several methods used for analyzing a solitary building's energy usage. One method involves the use of a neural network (NN) model. The current use of NN for building energy prediction typically requires the collection of hourly energy usage data from a single building using data loggers during several different seasons and occupancy levels in order to …

Application Of Phenology To Assist In Hyperspectral Species Classification Of A Northern Hardwood Forest, Gretchen Sprehe Jan 2005

Application Of Phenology To Assist In Hyperspectral Species Classification Of A Northern Hardwood Forest, Gretchen Sprehe

Theses

Tree species have unique spectral reflectance patterns that allows them to be both compared to other objects and to other types of trees. Increasing the spectral separation of such images may assist with surveying and forestry inventories. In past studies, most classifications were done with summer leaves, which darken and become very similar shades of green. This study utilized the phenology of trees to investigate how the changing colors of young or senescing leaves may assist in species classification based on aerial images. Images were taken of the Hubbard Brook Experimental Forest, which is mainly dominated by sugar maple (Acer …

Al2o3 Hosted Attenuated Phase Shift Mask Materials For 157 Nm, Yang Liu Jan 2005

Al2o3 Hosted Attenuated Phase Shift Mask Materials For 157 Nm, Yang Liu

Theses

The Semiconductor Industry Association Roadmap 2003 has put 157 nm optical lithography as the next generation lithography wavelength for the node of 70 nm integrated circuits and below. The small departure from 193 nm puts more challenge on imaging tools and processes. One of the crucial areas is the exploration of thin film optical materials for mask coatings at vacuum ultraviolet (VUV) wavelength. Attenuated Phase Shift Mask (APSM) is one of the optical enhancement technologies pushing critical dimension of lithography to diffraction limits. As no existing single material satisfies those demanding requirements of APSM, non-stoichiometric composite materials will be explored …
