  • The growth of the Internet, which I have been involved in, and the growth of mobile telephone services, which NTT DoCoMo has been a leader in, have been peculiarly interlinked and at the same time separate. The Internet is a lab experiment that broke free, and finds itself in a world of its own contriving, which it often does not understand. The mobile telephone world was developed for commercial purposes, and is in many respects the son of its father, the wired telephone system.

  • This is a substantially new and different edition of Systems Analysis and Design. We hope that the new materials bring it up to date and that we’ve kept the best of the old. It has been written for people studying systems analysis and design or who are already working in systems teams. People who are involved in the development of new systems or the development of new systems analysts, or both, have written it. It is intended to be a practical book, easy to read and easy to use. It follows the same structure as the previous edition and has new and updated material in it. There are...

  • An HVAC designer is almost certain to be faced with the need to write reports. The ability to produce an organized, understandable, and succinct report will go far toward establishing credibility with both superiors and clients. Writing a good report requires the same attributes needed for success in any other area: understanding of basic principles, planning and organization, and careful investigation.

  • Any value that you'll run across as an engineer will either be unitless or, more commonly, will have specific types of units attached to it. In order to solve a problem effectively, all the types of units should be consistent with each other, or should be in the same system. A system of units defines each of the basic unit types with respect to some measurement that can be easily duplicated, so that for example 5 ft. is the same length in Australia as it is in the United States. There are five commonly-used base unit types or dimensions that one might encounter (shown with their...

  • In a normal alternating current power system, the voltage varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear electrical load is connected to the system, it draws a sinusoidal current at the same frequency as the voltage (though usually not in phase with the voltage). When a non-linear load, such as a rectifier, is connected to the system, it draws a current that is not necessarily sinusoidal. The current waveform can become quite complex, depending on the type of load and its interaction with other components of the system.

  • This book is designed for a one-semester course on Nano- and Microelectromechanical Systems or Nano- and Microengineering. A typical background needed includes calculus, electromagnetics, and physics. The purpose of this book is to bring together in one place the various methods, techniques, and technologies that students and engineers need in solving a wide array of engineering problems in formulation, modeling, analysis, design, and optimization of high-performance microelectromechanical and nanoelectromechanical systems (MEMS and NEMS).

  • The most fundamental point to understand about the C++ I/O system is that it operates on streams. A stream is an abstraction that either produces or consumes information. A stream is linked to a physical device by the C++ I/O system. All streams behave in the same manner, even if the actual physical devices they are linked to differ. Because all streams act the same, the same I/O functions and operators can operate on virtually any type of device. For example, the same method that you use to write to the screen can be used to write to a disk...

  • In this demo, we present SciSumm, an interactive multi-document summarization system for scientific articles. The document collection to be summarized is a list of papers cited together within the same source article, otherwise known as a co-citation. At the heart of the approach is a topic based clustering of fragments extracted from each article based on queries generated from the context surrounding the co-cited list of papers.

  • In this paper we examine how the differences in modelling between different data driven systems performing the same NLP task can be exploited to yield a higher accuracy than the best individual system. We do this by means of an experiment involving the task of morpho-syntactic wordclass tagging. Four well-known tagger generators (Hidden Markov Model, Memory-Based, Transformation Rules and Maximum Entropy) are trained on the same corpus data. After comparison, their outputs are combined using several voting strategies and second stage classifiers. ...

  • The LoopStar 800 SONET Access System enables service providers to cost effectively deploy a fiber-based solution to address locations where copper-based M13 multiplexers are typically deployed. While providing an effective alternative to copper-based M13s, the LoopStar 800 can deliver other advanced services simultaneously from the same system. As a result, the LoopStar 800 provides increased network visibility through its SONET management features and supports other services without significantly increasing the per port cost over traditional M13 multiplexers....

  • Machine translation of locative prepositions is not straightforward, even between closely related languages. This paper discusses a system of translation of locative prepositions between English and French. The system is based on the premises that English and French do not always conceptualize objects in the same way, and that this accounts for the major differences in the ways that locative prepositions are used in these languages.

  • This paper describes a multi-lingual phrase-based Statistical Machine Translation system accessible by means of a Web page. The user can issue translation requests from Arabic, Chinese or Spanish into English. The same phrase-based statistical technology is employed to realize the three supported language-pairs. New language-pairs can be easily added to the demonstrator. The Web-based interface allows the use of the translation system to any computer connected to the Internet.

  • In the past the evaluation of machine translation systems has focused on single system evaluations because there were only few systems available. But now there are several commercial systems for the same language pair. This requires new methods of comparative evaluation. In the paper we propose a black-box method for comparing the lexical coverage of MT systems. The method is based on lists of words from different frequency classes. It is shown how these word lists can be compiled and used for testing. We also present the results of using our method on 6 MT systems that translate...

  • Given several systems’ automatic translations of the same sentence, we show how to combine them into a confusion network, whose various paths represent composite translations that could be considered in a subsequent rescoring step. We build our confusion networks using the method of Rosti et al. (2007), but, instead of forming alignments using the tercom script (Snover et al., 2006), we create alignments that minimize invWER (Leusch et al., 2003), a form of edit distance that permits properly nested block movements of substrings. ...

The enormous potentialities of the information implicitly stored in a standard printed dictionary or a MRD can only be evidenced and made explicit when the same data are given a new logical structure in a data base model, and exploited by appropriate software. ...
