Standing Up To Words: Writing and Resistance in Toni Morrison s A Mercy
No full textIn Toni Morrison s A Mercy, the protagonist represents both the historical and the contemporary African American author. As Mueller argues, her act of carving words into walls can be read as an act of resistance against the historical silencing of the black voice as well as politically against symbolic violence exercised through language
Data for "Mueller Matrix Extrapolations from Linear Partial Polarimetry"
No full textTo demonstrate our method for extrapolating full, depolarizing Mueller matrices from fewer than 16 measurements, we measured an ensemble of roughened plastic bricks using a Mueller imaging polarimeter and a linear Stokes camera. The Mueller matrix images from the Mueller imaging polarimeter and the images taken with four polarizer orientations from the linear Stokes camera are included.

Near-Infrared Human Eye Mueller Matrix Images
No full textNear-infrared Mueller matrix images of 20 human subjects' eyes.
Images were taken using a dual-rotating-retarder Mueller polarimeter. The human subjects were illuminated with a diffuse near-infrared LED light source (945-955 nm) where 0.0315 W/m2 was incident on the subject’s face and/or eye. Mueller matrix images were reconstructed from 25 polarimetric measurements taken over the course of approximately 15 seconds. Due to the small, random unconscious movements of the eye, image alignment code was applied in post-processing.

Real Estate Rental Growth Rates at Different Points in the Physical Market Cycle
No full textReal estate markets go through both physical cycles (demand and supply) that affect rental growth rates and financial cycles (capital flows to real estate) that affect property Prices (Mueller, 1995). This study develops a rental growth rate hypothesis based on a market’s position in the physical (demand-supply) market cycle. Using data from fifty-four office and industrial markets in the United States over a thirty-year period, an aggregated national average rental growth rate was calculated for each point in the cycle. An ANOVA test for differences of means found that the national average rental growth rates at each point in the cycle were statistically different. The results show local demand and supply, which interact to affect occupancy, are major determinants in rental growth rates. This research should help investors move from using a single rental growth rate for multiple year forecasts, to using yearly cycle driven rental growth rate estimates in their discounted cash flow projections.
Analysis and Modeling of Depolarization Effects in Mueller Matrix Spectroscopic Ellipsometry Data
No full textAbstractIn this paper we present importance of depolarization effects modeling to fit spectroscopic Mueller matrix ellipsometry data. The relevant theoretical background based on Mueller matrix formalism is presented. The sample of SiO2 layer (approx. 1μm thick) on silicon substrate is used to demonstrate depolarization effects in obtained experimental data. In the first step the presence of interferences in the layer is used for modeling of depolarization effects caused by finite spectral resolution of the Mueller matrix ellipsometer. In the next step the depolarization caused by focusing of the probe light is analyzed and modeled. Both finite spectral resolution and beam focusing is a common issue in the optical characterization of samples with lateral dimensions smaller than (commonly used) collimated beam. Therefore to fit experimental data with model it is important to assume those depolarization effect into model
Experiments with non-uniform sediment in case of bed-load transport
No full textAn experimental study was carried out in the framework of a research project concerning the development of a mathematical model for morphological computations in rivers in case of non-uniform sediment. The study consists of a series of laboratory experiments in a straight flume under steady, uniform (equilibrium) conditions with a restriction to bed-load transport and dune regime. The flume was fed upstream by different mixtures of two very narrow sieved size fractions. During one experiment the total amount and composition of the input mixture, the water discharge and the downstream water level were kept constant. When equilibrium was reached besides regular registrations of water and bed level the dunes were extensively sampled. The latter occurred in such a way that vertical probability distributions of the size fractions could be determined. The main results of the experiments are: (i) Vertical sorting of the size fractions occurred in all experiments: at the steep lee side of the dunes the coarse size fraction is generally deposited at a lower level than the fine size fraction. Differences in volume concentration per size fraction until 30% occur between upper and lower layers. (ii) A transition layer was found which is generally below the propagating dunes; it has a relatively coarse composition (vertical sorting:) and has a thickness of 0.1 - 0.5 H (H = average dune height). Exchange of size fractions between this layer and the upper bed layer occurs at a time scale much larger than the dune period. (iii) Because of the phenomena described above several assumptions in a mathematical model for non-uniform sediment (Ribberink, 1980) concerning the transport layer and the deposition/erosion of size fractions to/from non-moving bed are generally not fulfilled. (iv) Data are obtained for the verification and development of semi empirical components in the mathematical model (i.e. transportformula per size fraction, predictors for dune height and bed roughness).The theory of Egiazaroff (1965) concerning the critical bed shear stress per size fraction seems to be useful in a bed-load formula per size fraction of the type of Meyer-Peter & Mueller (1948). (v) A bed sampling technique was developed and suggestions are made concerning the conditions of a non -equilibrium experiment which has the aim to verify the above-mentioned mathematical model for non-uniform sediment.Hydraulic EngineeringCivil Engineering and Geoscience
Determination of Anisotropic Crystal Optical Properties Using Mueller Matrix Spectroscopic Ellipsometry
No full textAbstractIn this paper the Mueller matrix ellipsometry in the spectral range from 0.73 to 6.4eV measured using dual rotating compensator ellipsometer RC2 (Woollam company) is applied to study anisotropic crystals. First we summarize the effects of optical anisotropy to Mueller matrix spectra. As an example of an uniaxial sample we have characterized a Rutile (TiO2) tetragonal crystal. The optical axis of the sample is parallel to its surface. The sample is characterized at variable angle of incidence and variable azimuthal rotation angle. The Mueller matrix spectra are fitted to the model based on Kramers-Kronig consistent Basis spline and obtained optical functions are compared with tabulated data and ab-initio models based on first-principle calculated electronic structure

A Brief Guide for the Creation of Author-specific Citation Metrics and Publication Data Using the Thomson Reuters Web of Science and Scopus Databases
No full textThe objective of this guide is twofold. First, it shall enable interested readers to understand and reproduce the process of collecting author-specific citation metrics and publication data from the Thomson Reuters Web of Science and Scopus databases that is adopted in Andreoli-Versbach and Mueller-Langer (2013). Second, it presents the problems faced during the data collection process and the refined method of data collection we adopt to address related concerns. Thereby, it may serve interested readers as a guideline to accurately and efficiently retrieve citation metrics and publication information from Thomson Reuters Web of Science and Scopus in similar endeavors
