The second edition of Atoms, Radiation, and Radiation Protection has several important new features. SI units are employed throughout, the older units being defined 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, typeI and typeII errors, instrument response, and Monte Carlo radiationtransport computations.

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....

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.

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 oldstyle 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...

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.

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.

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.

Treetostring translation is syntaxaware and efﬁcient but sensitive to parsing errors. Foresttostring 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 subtrees within the ﬁrst best parse through binarization.

In this paper we investigate the beneﬁt of stochastic predictor components for the parsing quality which can be obtained with a rulebased 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. ...

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. errorfree feedback was assumed for the DFE, while in practice erroneous decision can be fed back, which results in error propagation....

Script injection attacks typically affect nonmalicious 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 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.

Under the name of ideal circuit network, it is easy to make us understand that digital circuits are independent of the inner status and their outputs just only depend on the inputs. They are time constants and therefore Boolean algebra is a special suitable means of describing. In fact propagation delay time of circuit system should be in thought firstly in designing circuit network. In that case Boolean algebra does not seems to be fully suitable for describing actual circuit systems.

We introduce a new approach to transitionbased dependency parsing in which the parser does not directly construct a dependency structure, but rather an undirected graph, which is then converted into a directed dependency tree in a postprocessing step. This alleviates error propagation, since undirected parsers do not need to observe the singlehead constraint. Undirected parsers can be obtained by simplifying existing transitionbased parsers satisfying certain conditions.

For Chinese POS tagging, word segmentation is a preliminary step. To avoid error propagation and improve segmentation by utilizing POS information, segmentation and tagging can be performed simultaneously. A challenge for this joint approach is the large combined search space, which makes efﬁcient decoding very hard. Recent research has explored the integration of segmentation and POS tagging, by decoding under restricted versions of the full combined search space.
