Experimental investigation of hypersonic buzz on a high cross-range shuttle configuration

A wind tunnel investigation has been conducted to determine the nature of an unsteady hypersonic flow phenomenon, often referred to as hypersonic buzz, on a 1:100 scale model representative of a high cross-range shuttle configuration. The tests, conducted in helium at a nominal Mach number of 17.5, were specifically directed at obtaining a better understanding of the character of the hypersonic flow field in the vicinity of a deflected control surface. Power spectral densities and root mean squared values of surface pressure fluctuations are presented along with observations made from high speed motion pictures, schlieren and oil flow photographs. Flap deflections of 0, 20, 30, 35, 40 and 60 deg were tested at various angles of attack from 0 deg to 37 deg. It is quite clear from these tests that, under certain conditions, extremely unstable hypersonic flow patterns are formed

Mining for Natural Resources

In this activity, students mine the chips from chocolate chip cookies. They weigh the cookies before and after mining, weigh the chips, and calculate the percent yield. This lab is designed to give students a better understanding of the processes involved in harvesting a natural resource and the impact it has on their environment and community. Analysis and conclusion questions focus on the fact that the mining of nonrenewable natural resources has a dramatic effect on our environment. Educational levels: High school, Middle school

Examining the Theoretical Relationship Between Support Needs and Adaptive Behavior: A Construct Analysis of Children with Intellectual Disability

This dissertation is composed of four stand-alone yet linked chapters. Chapter 1 provides an overview of the theoretical underpinnings of the constructs of adaptive behavior and support needs and their evolution throughout history. There is also a review of the limited literature available examining the relationship between the two constructs that demonstrates the incongruity among outcomes. Chapter 2 examines the construct validity of two new instruments developed by the American Association on Intellectual and Developmental Disabilities the Diagnostic Adaptive Behavior Scale (DABS) and the Supports Intensity Scale for Children (Field Test Version 1.1) (SIS-Children). The chapter provides evidence for the construct validity of the two instruments to measure the prospective constructs of adaptive behavior and support needs through confirmatory factor analysis. Chapter 3 builds on the results from Chapter 2 and goes one step further by examining the theoretical relationship between the constructs of adaptive behavior and support needs in children ages 5-16 with intellectual disability through structural equation modeling. The findings suggest that while the two constructs are intimately related, they do in-fact represent two distinct constructs. Finally, Chapter 4 summarizes the previous chapters and draws from them conclusions and implications for future research, policy, and practice for children with intellectual and developmental disabilities

LIPIcs

We revisit the problem of estimating entropy of discrete distributions from independent samples, studied recently by Acharya, Orlitsky, Suresh and Tyagi (SODA 2015), improving their upper and lower bounds on the necessary sample size n. For estimating Renyi entropy of order alpha, up to constant accuracy and error probability, we show the following * Upper bounds n = O(1) 2^{(1-1/alpha)H_alpha} for integer alpha>1, as the worst case over distributions with Renyi entropy equal to H_alpha. * Lower bounds n = Omega(1) K^{1-1/alpha} for any real alpha>1, with the constant being an inverse polynomial of the accuracy, as the worst case over all distributions on K elements. Our upper bounds essentially replace the alphabet size by a factor exponential in the entropy, which offers improvements especially in low or medium entropy regimes (interesting for example in anomaly detection). As for the lower bounds, our proof explicitly shows how the complexity depends on both alphabet and accuracy, partially solving the open problem posted in previous works. The argument for upper bounds derives a clean identity for the variance of falling-power sum of a multinomial distribution. Our approach for lower bounds utilizes convex optimization to find a distribution with possibly worse estimation performance, and may be of independent interest as a tool to work with Le Cam’s two point method

Extractors: Low Entropy Requirements Colliding With Non-Malleability

The known constructions of negligible error (non-malleable) two-source extractors can be broadly classified in three categories: (1) Constructions where one source has min-entropy rate about $1/2$, the other source can have small min-entropy rate, but the extractor doesn't guarantee non-malleability. (2) Constructions where one source is uniform, and the other can have small min-entropy rate, and the extractor guarantees non-malleability when the uniform source is tampered. (3) Constructions where both sources have entropy rate very close to $1$ and the extractor guarantees non-malleability against the tampering of both sources. We introduce a new notion of collision resistant extractors and in using it we obtain a strong two source non-malleable extractor where we require the first source to have $0.8$ entropy rate and the other source can have min-entropy polylogarithmic in the length of the source. We show how the above extractor can be applied to obtain a non-malleable extractor with output rate $\frac 1 2$, which is optimal. We also show how, by using our extractor and extending the known protocol, one can obtain a privacy amplification secure against memory tampering where the size of the secret output is almost optimal

Estetyka, erotyka i parytet płciowy: Historia piękna i Historia brzydoty pod redakcją Umberta Eco

Even the covers of these books show the contrast between men and women. How esthetic values build a feedback with sexual parity?

The Flash Point of Toruń Tumult (1724) and Monologue-Dialog Between Two Historians: Woldemar Gastpary — Stanisław Salmonowicz

Paper is a kind of comparative analysis „discordant-concordant” images of accidents which took place on 16 and 17 July 1724, also known as Toruń tumult: two outstanding scholars — Woldemar Gastpary and Stanisław Salmonowicz — presented two symmetrical but opposed views of facts. Both scholars try to descript this facts from the Protestant and from the Catholic perspective. Inspired by Tumult monologue-dialog between Protestants and Catholics lead to basic methodological issue and help to visualize a state of osmosis between two spaces: a faith and a knowledge may contribute themselves
