Ferroelectric Polymer Langmuir–Blodgett Films For Nonvolatile Memory Applications, Stephen Ducharme, Timothy J. Reece, Christina M. Othon, R. K. Rannow

Department of Physics and Astronomy: Faculty Publications

We review the potential for integrating ferroelectric polymer Langmuir–Blodgett (LB) films with semiconductor technology to produce nonvolatile ferroelectric random-access memory (NV-FRAM or NV-FeRAM) and data-storage devices. The prototype material is a copolymer consisting of 70% vinylidene fluoride (VDF) and 30% trifluoroethylene (TrFE), or P(VDF-TrFE 70:30). Recent work with LB films and more conventional solventformed films shows that the VDF copolymers are promising materials for nonvolatile memory applications. The prototype device is themetal–ferroelectric–insulator–semiconductor (MFIS) capacitance memory. Field-effect transistor (FET)-based devices are also discussed. The LB films afford devices with low-voltage operation, but there are two important technical hurdles that must be …

Explaining The American Norm Against Litigation, Shawn J. Bayern

Scholarly Publications

In the United States, a social norm discourages people from vindicating at least some of their rights in court. However, if courts are an instrument of justice and of sound public policy-for instance, if they provide fair compensation for injured parties and efficient incentives for potential injurers-then a norm against using courts is puzzling.

This Comment explores and evaluates explanations for the norm against litigation; the Comment's goal is to provide a plausible account of the norm. As such, the Comment is largely descriptive. However, normative implications may follow from my exploration; for instance, to the extent that an explanation …

Issues Of Processing And Multiple Testing Of Seldi-Tof Ms Proteomic Data, Merrill D. Birkner, Alan E. Hubbard, Mark J. Van Der Laan, Christine F. Skibola, Christine M. Hegedus, Martyn T. Smith

U.C. Berkeley Division of Biostatistics Working Paper Series

A new data filtering method for SELDI-TOF MS proteomic spectra data is described. We examined technical repeats (2 per subject) of intensity versus m/z (mass/charge) of bone marrow cell lysate for two groups of childhood leukemia patients: acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). As others have noted, the type of data processing as well as experimental variability can have a disproportionate impact on the list of "interesting" proteins (see Baggerly et al. (2004)). We propose a list of processing and multiple testing techniques to correct for 1) background drift; 2) filtering using smooth regression and cross-validated bandwidth …

The Relationship Between The Number Of Shots And The Quality Of Gamma Knife Radiosurgeries, D Cheek, Allen G. Holder, M Fuss, B Salter

Mathematics Faculty Research

Radiosurgery is a non-invasive alternative to brain surgery that uses a single focused application of high radiation to destroy intracerebral target tissues. A Gamma Knife delivers such treatments by using 201 cylindrically collimated cobalt-60 sources that are arranged in a hemispherical pattern and aimed to a common focal point. The accumulation of radiation at the focal point, called a \shot" due to the spherical nature of the dose distribution, is used to ablate (or destroy) target tissue in the brain. If the target is small and spherical, it is easily treated by choosing one of four available collimators (4, 8, …

Monte-Carlo-Type Techniques For Processing Interval Uncertainty, And Their Potential Engineering Applications, Vladik Kreinovich, J. Beck, Carlos M. Ferregut, A. Sanchez, George R. Keller, Matthew G. Averill, Scott A. Starks

Departmental Technical Reports (CS)

In engineering applications, we need to make decisions under uncertainty. Traditionally, in engineering, statistical methods are used, methods assuming that we know the probability distribution of different uncertain parameters. Usually, we can safely linearize the dependence of the desired quantities y (e.g., stress at different structural points) on the uncertain parameters xi - thus enabling sensitivity analysis. Often, the number n of uncertain parameters is huge, so sensitivity analysis leads to a lot of computation time. To speed up the processing, we propose to use special Monte-Carlo-type simulations.

Loss Aware Rate Allocations In H.263 Coded Video Transmissions, Xiao Su, Benjamin Wah

Faculty Publications

For packet video, information loss and bandwidth limitation are two factors that affect video playback quality. Traditional rate allocation approaches have focused on optimizing video quality under bandwidth constraint alone. However, in the best-effort Internet, packets carrying video data are susceptible to losses, which need to be reconstructed at the receiver side. In this paper, we propose loss aware rate allocations in both group-of-block (GOB) level and macroblock level, given that certain packets are lost during transmissions and reconstructed using simple interpolation methods at the receiver side. Experimental results show that our proposed algorithms can produce videos of higher quality …

A Framework For Management Of Semistructured Probabilistic Data, Wenzhong Zhao, Alex Dekhtyar, Judy Goldsmith

Computer Science and Software Engineering

This paper describes the theoretical framework and implementation of a database management system for storing and manipulating diverse probability distributions of discrete random variables with finite domains, and associated information. A formal Semistructured Probabilistic Object (SPO) data model and a Semistructured Probabilistic Query Algebra (SP-algebra) are proposed. The SP-algebra supports standard database queries as well as some specific to probabilities, such as conditionalization and marginalization. Thus, the Semistructured Probabilistic Database may be used as a backend to any application that involves the management of large quantities of probabilistic information, such as building stochastic models. The implementation uses XML encoding of …

Final Environmental Assessment And Finding Of No Significant Impact For The Proposed Safety Of Dams Modifications And Bridge Reconstruction, Provo Area Office, Upper Colorado Region, Bureau Of Reclamation, U.S. Department Of Transportation, Utah Division, Federal Highway Administration, U.S. Department Of The Interior

All U.S. Government Documents (Utah Regional Depository)

The Bureau of Reclamation, Provo Area Office (Reclamation) proposes to replace the concrete spillway structure at Scofield Dam, the principal feature of the Scofield Project. This construction project would be completed under the Safety of Dams (SOD) Act of 1978 (Public Law 95-578, as amended). The proposed SOD modifications would correct safety deficiencies of the dam without affecting the purpose, or benefits of the dam. Reclamation also proposes to replace the existing gate house at its current position on the crest of the dam. This building is in poor condition and would be replaced with either a new concrete structure …

The Relationship Between Meteorological Patterns And Rural Ground Ozone Concentration, Dasen Kendrick

Masters Theses & Specialist Projects

Throughout the United States, many areas exceed the level of safe ground ozone (O3) concentration. Non-natural emissions made as result of daily human activities and natural emissions react photochemically to produce ground O3 concentration. Variation in ground O3 concentration is controlled by local and regional emissions, synoptic and mesoscale meteorology, and boundary layer chemistry and dynamics. When the right meteorological variables are present, rural areas can have unhealthy air conditions with high levels of ground O3 concentration similar to that of metropolitan areas. Particular ground O3 concentration episodes were analyzed to summarize what meteorological variables constitute a healthy or hazardous …

Triangle Grouping And Structure Recovery For 3d Building Modelling And Visualization, Joe Hegarty, James Carswell

Conference papers

Location based and spatial technologies research for the web has endless application for mobile/position content delivery (m-commerce or pcommerce). By exploiting the inherent location-based intelligence of the underling spatial component, relevant examples can include geometrically accurate and photo realistic virtual representations for: property assessments; land/marine information systems; routing information; on-line shopping; cultural heritage/tourist information/sites; etc. A major challenge for this technology is its reliance on professional developers when creating the virtual worlds used for web-based navigation of these services. This paper describes SAMATS, a Semi-Automated Modeling And Texturing System, which has the capability of producing geometrically accurate and photorealistic VR …

Existence And Uniqueness Of V-Asymptotic Expansions And Colombeau’S Generalized Numbers, Todor D. Todorov

Mathematics

We define a type of generalized asymptotic series called v-asymptotic. We show that every function with moderate growth at infinity has a v-asymptotic expansion. We also describe the set of v-asymptotic series, where a given function with moderate growth has a unique v-asymptotic expansion. As an application to random matrix theory we calculate the coefficients and establish the uniqueness of the v-asymptotic expansion of an integral with a large parameter. As another application (with significance in the non-linear theory of generalized functions) we show that every Colombeau’s generalized number has a v-asymptotic expansion. A similar …

Natural Flow And Salt Computation Methods, Calendar Years 1971-1995, James Prairie, Russell Callejo

All U.S. Government Documents (Utah Regional Depository)

This paper documents the steps taken to compute natural flow and salt in the Upper and Lower Colorado River Basins from 1971-1995. Natural flow and salt data are hydrologic input data required in the CRSS planning model. The methods used to compute natural flow and salt described in this paper have changed from previous methods as a result of recent research. This research found data and methodological inconsistency in past methods to compute natural flow and salt was compared to data and methods used in the CRSS planning model (Prairie and Fulp, 1999). To assure the computation of natural flow …

It serves as a centralized data repository, acquiring range wide information regarding rare plant and animal species for use by land managers as well as for the evaluation of conservation needs. As well as being used by government agencies, data are used in responding to requests for information from non-government organizations and private interests. Data can be used in the assessment of species’ conservation status state-wide and, in coordination …

Fisheries Research Report No. 152 - Development Of A Dna Database For Compliance And Management Of Western Australian Sharks., Rory Mcauley, K. Ho, R. Thomas

Fisheries Research Reports

Final FRDC Report - Project 2003/067

The capability to identify individual shark species from processed body parts is necessary for the WA Department of Fisheries to ensure the compliance of all WA fisheries with both existing protected species regulations and proposed new management measures for commercially important shark species. This project established a reference database of genetic profiles or ‘fingerprints’ for nine of Western Australia’s protected and commercially important shark species. Fingerprints from a 10th species, the shortfin mako (Isurus oxyrinchus) could not be obtained due to probable primer sequence mismatching. The database, in conjunction with an associated inspection and …

Klein Paradox With Spin-Resolved Electrons And Positrons, P Krekora, Q Su, Rainer Grobe

Faculty publications – Physics

Using numerical solutions to relativistic quantum field theory with space-time resolution, we illustrate how an incoming electron wave packet with a definite spin scatters off a supercritical potential step. We show that the production rate is reduced of only those electrons that have the same spin as the incoming electron is reduced. This spin-resolved result further clarifies the importance of the Pauli-exclusion principle for the Klein paradox.

An Investigation Of Rupture In Thin Fluid Films, Robin Baur

HMC Senior Theses

The behavior of a fluid with a thin capillary meniscus can be modelled on a one-dimensional domain Ω = [−L, L] by the thin film equation ht = −(hnhxxx)x with boundary conditions hx(±L) = ±α (giving a fixed contact angle) and hxxx(±L) = 0 (prohibiting mass flux). It is desirable to know whether or not such a film experiences rupture; that is, whether there exists some x0, t0 (with t0 possibly ∞) such that h(x0, t0) = 0, corresponding to the appearance of a dry spot. We approach this problem using energy methods, which use the conservation or dissipation of …

Focused-Laser Interferometric Position Sensor, Stephen J. Friedman, Brett E. Barwick, Herman Batelaan

Department of Physics and Astronomy: Faculty Publications

We describe a simple method to measure the position shifts of an object with a range of tens of micrometers using a focused-laser (FL) interferometric position sensor. In this article we examine the effects of mechanical vibration on FL and Michelson interferometers. We tested both interferometers using vibration amplitudes ranging from 0 to 20 μm. Our FL interferometer has a resolution much better than the diffraction grating periodicities of 10 and 14 μm used in our experiments. A FL interferometer provides improved mechanical stability at the expense of spatial resolution. Our experimental results show that Michelson interferometers cannot be used …

Numerical Modeling Of Hohlraum Radiation Conditions: Spatial And Spectral Variations Due To Sample Position, Beam Pointing, And Hohlraum Geometry, David H. Cohen, O. L. Landen, J. J. Macfarlane

Physics & Astronomy Faculty Works

View-factor simulations are presented of the spatially varying radiation conditions inside double-ended gold Hohlraums and single-ended gold Hohlraums ('' halfraums '') used in inertial confinement fusion and high-energy density physics experiments [J. Lindl, Phys. Plasmas 11, 339 (2004); M. D. Rosen, Phys. Plasmas 3, 1803 (1996)]. It is shown that in many circumstances, the common assumption that the Hohlraum '' drive '' can be characterized by a single temperature is too simplistic. Specifically, the radiation conditions seen by an experimental package can differ significantly from the wall reemission measured through diagnostic holes or laser entrance holes (LEHs) by absolutely calibrated …

Disc Separation Of The Schur Complement Of Diagonally Dominant Matrices And Determinantal Bounds, Jianzhou Liu, Fuzhen Zhang

Mathematics Faculty Articles

We consider the Gersgorin disc separation from the origin for (doubly) diagonally dominant matrices and their Schur complements, showing that the separation of the Schur complement of a (doubly) diagonally dominant matrix is greater than that of the original grand matrix. As application we discuss the localization of eigenvalues and present some upper and lower bounds for the determinant of diagonally dominant matrices.

Developing A Strategic Is Plan For The Cherry Creek Sneak, Stephanie Bass

Regis University Student Publications (comprehensive collection)

The Cherry Creek Sneak is the 3rd largest 5-mile race in the United States.Currently, 10% of the proceeds from the race are donated to the ColoradoGovernor's Council to fight childhood obesity. The co-owners of the race, Pat Downing and Paula Tiernen, live in different states, and because of this, are unable to manage The Cherry Creak Sneak, or any business regarding the race efficiently. In order to continue the race in the future, they have requested that the Cherry Creek Sneak website be the place where their business is conducted. The goal of this project, therefore, is to create a …

The Residual Effect Of Novice Primary Teachers On Reading Achievement Scores, Connie Mayo

Masters Theses & Specialist Projects

This dissertation was an exploratory investigation of the residual effect of novice primary teachers on reading achievement scores. The study employed the theory of pedagogical content knowledge as a basis for understanding teacher expertise and comparing the expert teacher to the novice teacher. The research sought to answer two major questions; (a) Is there a statistically significant difference between the reading achievement, (measured two years later) of students taught by teachers of differing experience levels in primary grades and the state mean for the appropriate grade level? and (b) Is there a statistically significant difference among the two-year-later reading achievement …
