the second edition of atoms, radiation, and radiation protection has several important new features. si units are employed throughout, the older units being de-fined but used sparingly. there are two new chapters. one is on statistics for health physics. it starts with the description of radioactive decay as a bernoulli process and treats sample counting, propagation of error, limits of detection, type-i and type-ii errors, instrument response, and monte carlo radiation-transport computations.

• ### TRITIUM MEASUREMENT TECHNIQUES - NCRP REPORT No. 47

As a consequence of the increasing importance of tritium resulting from nuclear fission and neutron activation, from its use in accelerators, from its use in research and industry, and from its use in the investigation of the environment and its distribution in the environment, the NCRP designated a scientific committee to prepare a report on the currently acceptable methods of measuring tritium. This report is particularly aimed in assisting an individual to select a procedure suitable to the problem at hand....

• ### ELECTROMAGNETIC WAVES PROPAGATION IN COMPLEX MATTER

This book is based on the contributions of several authors in electromagnetic waves propagations. Several issues are considered. The contents of most of the chapters are highlighting non classic presentation of wave propagation and interaction with matters. This book bridges the gap between physics and engineering in these issues. Each chapter keeps the author notation that the reader should be aware of as he reads from chapter to the other. The author’s notations are kept in order to eliminate any possible unintentional errors that might lead to confusion.

• ### Acetaria: A Discourse of Sallets

This edition of Acetaria is a faithful reprint of the First Edition of 1699, with the correction of a few obvious typographical errors, and those noted in the Errata of the original edition. Whereas no attempt has been made to reproduce the typography of the original, the spirit has been retained, and the vagaries of spelling and punctuation have been carefully followed; also the old-style S [s] has been retained. Much of the flavour of Acetaria is lost if it is scanned too hurriedly; and one should remember also that Latin and Greek were the gauge of a man of letters, and if the titles...

• ### A non parametric propagation condition identification method and non line of sight mitigation algorithm for wireless sensor network

The localization technology is critical for the application of the WSN. The obstacles induce the larger non-line of sight (NLOS) error and it may decrease the localization accuracy. In this paper, we mainly investigate the non-line of sight localization problem for WSN.

• ### Error Calculus for Finance and Physics: The Language of Dirichlet Forms

Our primary objective herein is not to determine how approximate calculations introduce errors into situations with accurate hypotheses, but instead to study how rigorous calculations transmit errors due to inaccurate parameters or hypotheses. Unlike quantities represented by entire numbers, the continuous quantities generated from physics, economics or engineering sciences, as represented by one or several real numbers, are compromised by errors.

• ### Handbook of Applied Cryptography - chap6

Stream ciphers are an important class of encryption algorithms. They encrypt individual characters (usually binary digits) of a plaintext message one at a time, using an encryption transformation which varies with time. By contrast, block ciphers (Chapter 7) tend to simultaneously encrypt groups of characters of a plaintext message using a fixed encryption transformation. Stream ciphers are generally faster than block ciphers in hardware, and have less complex hardware circuitry. They are also more appropriate, and in some cases mandatory (e.g.

• ### Báo cáo khoa học: "Joint Inference of Named Entity Recognition and Normalization for Tweets"

Tweets represent a critical source of fresh information, in which named entities occur frequently with rich variations. We study the problem of named entity normalization (NEN) for tweets. Two main challenges are the errors propagated from named entity recognition (NER) and the dearth of information in a single tweet.

• ### Báo cáo khoa học: "Binarized Forest to String Translation"

Tree-to-string translation is syntax-aware and efﬁcient but sensitive to parsing errors. Forestto-string translation approaches mitigate the risk of propagating parser errors into translation errors by considering a forest of alternative trees, as generated by a source language parser. We propose an alternative approach to generating forests that is based on combining sub-trees within the ﬁrst best parse through binarization.

• ### Báo cáo khoa học: "Hybrid Parsing: Using Probabilistic Models as Predictors for a Symbolic Parser"

In this paper we investigate the beneﬁt of stochastic predictor components for the parsing quality which can be obtained with a rule-based dependency grammar. By including a chunker, a supertagger, a PP attacher, and a fast probabilistic parser we were able to improve upon the baseline by 3.2%, bringing the overall labelled accuracy to 91.1% on the German NEGRA corpus. We attribute the successful integration to the ability of the underlying grammar model to combine uncertain evidence in a soft manner, thus avoiding the problem of error propagation. ...

• ### Peak load forecasting for Vietnam national power system to 2030

Using the feed-forward back propagation (FFBP) method, a modified model of neural network, this paper will introduce a new long-term prediction approach for the maximum load power of Vietnam. Results from simulation indicate a considerable correlation of three parameters regarding electric power consumption demand, GDP growth rate, and maximum load power demand; the mean error of suggested model is about 1.92%. This is a reasonable range of mean error for a long-term prediction where the correlation of variables is not explicit.

• ### Unaccounted uncertainty from qPCR efficiency estimates entails uncontrolled false positive rates

Accurate adjustment for the amplification efficiency (AE) is an important part of real-time quantitative polymerase chain reaction (qPCR) experiments. The most commonly used correction strategy is to estimate the AE by dilution experiments and use this as a plug-in when efficiency correcting the Cq.

Error Propagation A single bit error in transmission can create errors in several in the corresponding block.

Practical Considerationsof Wideband AQAM In deriving the upper bound performance of wideband AQAM portrayed in Figure 4.21(b), various assumptions were made and stated in Section 4.3.1. However, in order to provide a more accurate comparison between AQAM and constituent fixed modulation modes, those its assumptions must be justified and their effects have to be investigated. Specifically, perfect, i.e. error-free feedback was assumed for the DFE, while in practice erroneous decision can be fed back, which results in error propagation....

• ### FEEDBACK REPORT ON THE EUROPEAN OUTREACH EVENT ON EFRAG PROACTIVE DISCUSSION PAPERS

Script injection attacks typically affect non-malicious users and succeed without compromising Web applica- tion servers or networks. For example, in 2005, the self- propagating Samy worm on MySpace used script injec- tion to infect over a million users [24]. As a MySpace user viewed the MySpace page of another, infected user, the worm script would execute and send a page update request to the server, causing the worm script to be in- cluded also on the viewing user’s page.

• ### Multisensor thiết bị đo đạc thiết kế 6o (P8)

MULTISENSOR ARCHITECTURES AND ERROR PROPAGATION The purpose of this chapter is to extend the data acquisition error analysis of the preceding chapters to provide understanding about how errors originating in multisensor architectures combine and propagate in algorithmic computations. This development is focused on the wider applications of sensor integration for improving data characterization rather than the narrower applications of sensor fusion employed for data ambiguity reduction.
