The Typical American Source Materials

There are three components to the resource materials in this project. There are: a packet of approximately one hundred small (3\u27\u27 x 5\u27\u27) index cards, a packet of about two hundred large ( 4\u27\u27 x 6\u27\u27) index cards, and a type-written paper. The small index cards contain statistical information, the large index cards contain quotations, and the paper has an introduction to the entire project and the numerical distribution of responses to a questionnarie entitled: The Typical American . In the introduction, the basic tenets and format of the project are given as well as possible uses for it. The materials may be used collectively as a single resource or separately in any of its three parts. The materials are to be used as teaching aids. They may be used in classes of foreign students studying English in the United States or students of English abroad with an interest in American culture. The materials may also be used for Americans who will have foreign students. The materials are to be used primarily as an orientation to the culture and society of the United States of America. They are meant specifically to deal with the collectively perceived entity known as the American . The materials may be used to heighten the awareness of Americans to preconceptions about their culture and how they may be viewed as representatives of it

Testing normality in any dimension by Fourier methods in a multivariate Stein equation

We study a novel class of affine-invariant and consistent tests for multivariate normality. The tests are based on a characterization of the standard d-variate normal distribution by way of the unique solution of an initial value problem connected to a partial differential equation, which is motivated by a multivariate Stein equation. The test criterion is a suitably weighted L2-statistic. We derive the limit distribution of the test statistic under the null hypothesis as well as under contiguous and fixed alternatives to normality. A consistent estimator of the limiting variance under fixed alternatives, as well as an asymptotic confidence interval of the distance of an underlying alternative with respect to the multivariate normal law, is derived. In simulation studies, we show that the tests are strong in comparison with prominent competitors and that the empirical coverage rate of the asymptotic confidence interval converges to the nominal level. We present a real data example and also outline topics for further research

On the use of structured adsorbents in cyclic adsorption processes

Structured adsorbents have been around for some time. However, commercialization for use in PSA and TSA processes has been extremely limited. There are just a few examples that the authors know about. Yet, the potential for a structured adsorbent to minimize pressure drop and alleviate particle fluidization and attrition issues is enormous. The objective of this work is to provide an overview on the use of structured adsorbents in cyclic adsorption processes, such as PSA and TSA processes. This objective will be accomplished by first presenting a brief literature review of the subject, then by discussing one of the successful commercial applications, and finally by presenting the efforts ongoing in Ritter’s adsorption laboratory. They have been working with Catacel (now owned by Johnson Matthey) on a metal foil, parallel channel, structured adsorbent coated with zeolite crystals. A photograph is this type of structure is shown in the photographs below. This material is being studied for use in both PSA and TSA processes. The latest results from Ritter’s group will be presented at this conference. Please click Additional Files below to see the full abstract

A space-time hybrid hourly rainfall model for derived flood frequency analysis

For derived flood frequency analysis based on hydrological modelling long continuous precipitation time series with high temporal resolution are needed. Often, the observation network with recording rainfall gauges is poor, especially regarding the limited length of the available rainfall time series. Stochastic precipitation synthesis is a good alternative either to extend or to regionalise rainfall series to provide adequate input for long-term rainfall-runoff modelling with subsequent estimation of design floods. Here, a new two step procedure for stochastic synthesis of continuous hourly space-time rainfall is proposed and tested for the extension of short observed precipitation time series. First, a single-site alternating renewal model is presented to simulate independent hourly precipitation time series for several locations. The alternating renewal model describes wet spell durations, dry spell durations and wet spell intensities using univariate frequency distributions separately for two seasons. The dependence between wet spell intensity and duration is accounted for by 2-copulas. For disaggregation of the wet spells into hourly intensities a predefined profile is used. In the second step a multi-site resampling procedure is applied on the synthetic point rainfall event series to reproduce the spatial dependence structure of rainfall. Resampling is carried out successively on all synthetic event series using simulated annealing with an objective function considering three bivariate spatial rainfall characteristics. In a case study synthetic precipitation is generated for some locations with short observation records in two mesoscale catchments of the Bode river basin located in northern Germany. The synthetic rainfall data are then applied for derived flood frequency analysis using the hydrological model HEC-HMS. The results show good performance in reproducing average and extreme rainfall characteristics as well as in reproducing observed flood frequencies. The presented model has the potential to be used for ungauged locations through regionalisation of the model parameters.BMBF/FKZ:033068

Novelty Search in Competitive Coevolution

One of the main motivations for the use of competitive coevolution systems is their ability to capitalise on arms races between competing species to evolve increasingly sophisticated solutions. Such arms races can, however, be hard to sustain, and it has been shown that the competing species often converge prematurely to certain classes of behaviours. In this paper, we investigate if and how novelty search, an evolutionary technique driven by behavioural novelty, can overcome convergence in coevolution. We propose three methods for applying novelty search to coevolutionary systems with two species: (i) score both populations according to behavioural novelty; (ii) score one population according to novelty, and the other according to fitness; and (iii) score both populations with a combination of novelty and fitness. We evaluate the methods in a predator-prey pursuit task. Our results show that novelty-based approaches can evolve a significantly more diverse set of solutions, when compared to traditional fitness-based coevolution.Comment: To appear in 13th International Conference on Parallel Problem Solving from Nature (PPSN 2014

Anisotropy in the helicity modulus of a 3D XY-model: application to YBCO

We present a Monte Carlo study of the helicity moduli of an anisotropic classical three-dimensional (3D) XY-model of YBCO in superconducting state. It is found that both the ab-plane and the c-axis helicity moduli, which are proportional to the inverse square of the corresponding magnetic field penetration depth, vary linearly with temperature at low temperatures. The result for the c-axis helicity modulus is in disagreement with the experiments on high quality samples of YBCO. Thus we conclude that purely classical phase fluctuations of the superconducting order parameter cannot account for the observed c-axis electrodynamics of YBCO.Comment: 7 pages, 1 figur

Online Communication Technology and Relational Development

Key to success in negotiation is managing and enhancing relationships. This concept can be difficult to convey in short-term executive training courses where students have little time for relational development. Not to worry: the authors assert that by strategically using online communication before, during, and after such courses, students can effectively both train for, and depend on, good relations at a distance

Magnetization Jump in a Model for Flux Lattice Melting at Low Magnetic Fields

Using a frustrated XY model on a lattice with open boundary conditions, we numerically study the magnetization change near a flux lattice melting transition at low fields. In both two and three dimensions, we find that the melting transition is followed at a higher temperature by the onset of large dissipation associated with the zero-field XY transition. It is characterized by the proliferation of vortex-antivortex pairs (in 2D) or vortex loops (in 3D). At the upper transition, there is a sharp increase in magnetization, in qualitative agreement with recent local Hall probe experiments.Comment: updated figures and texts. new movies available at http://www.physics.ohio-state.edu:80/~ryu/jj.html.
