  • As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.

  • Expert Indexing in Oracle Database 11g is about the one database structure at the heart of almost all performance concerns: the index. Database system performance is one of the top concerns in information technology today. Administrators struggle to keep up with the explosion of access and activity driven by the proliferation of computing into everything from phones to tablets to PCs in our increasingly connected world.

  • This paper studies the impact of written language variations and the way it affects the capitalization task over time. A discriminative approach, based on maximum entropy models, is proposed to perform capitalization, taking the language changes into consideration. The proposed method makes it possible to use large corpora for training. The evaluation is performed over newspaper corpora using different testing periods. The achieved results reveal a strong relation between the capitalization performance and the elapsed time between the training and testing data periods. ...

  • In this paper, we propose adding long-term grammatical information in a Whole Sentence Maximun Entropy Language Model (WSME) in order to improve the performance of the model. The grammatical information was added to the WSME model as features and were obtained from a Stochastic Context-Free grammar. Finally, experiments using a part of the Penn Treebank corpus were carried out and significant improvements were acheived.

  • Typically, the lexicon models used in statistical machine translation systems do not include any kind of linguistic or contextual information, which often leads to problems in performing a correct word sense disambiguation. One way to deal with this problem within the statistical framework is to use maximum entropy methods. In this paper, we present how to use this type of information within a statistical machine translation system. We show that it is possible to significantly decrease training and test corpus perplexity of the translation models. ...

  • This paper investigates two elements of Maximum Entropy tagging: the use of a correction feature in the Generalised Iterative Scaling (Gis) estimation algorithm, and techniques for model smoothing. We show analytically and empirically that the correction feature, assumed to be required for the correctness of GIS, is unnecessary. We also explore the use of a Gaussian prior and a simple cutoff for smoothing. The experiments are performed with two tagsets: the standard Penn Treebank POS tagset and the larger set of lexical types from Combinatory Categorial Grammar. ...

  • We discuss text summarization in terms of maximum coverage problem and its variant. We explore some decoding algorithms including the ones never used in this summarization formulation, such as a greedy algorithm with performance guarantee, a randomized algorithm, and a branch-andbound method. On the basis of the results of comparative experiments, we also augment the summarization model so that it takes into account the relevance to the document cluster.

  • If you’ve looked at a few 8051 datasheets, other 8051 books or flicked through the chapters in this guide, you may be left thinking that it is necessary to be an 8051 expert to produce workable programs with C51. Nothing could be further from the truth. It is perfectly possible to write real commercial programs with nothing more than a reasonable knowledge of the ISO C language and some appreciation of hardware. However, to get the maximum performance from the 8051 family, knowing a few tricks is very useful. This is particularly true if you are working on a very cost-sensitive...

  • Much has been written in the past few years on Customer Satisfaction measurement models in order to study the relationship between satisfaction and market share, and the impact of customer switching barriers (Fornell 1992) in terms of customer satisfaction Index (CSI). A Customer Satisfaction Index quantifies the level of profitable satisfaction of a particular customer base and specifies the impact of that satisfaction on the chosen measure(s) of economic performance.

  • ‘In my experience a major shortcoming of most “how to” books on leadership and management is that they purport to offer “Silver Bullets” – magical solutions that, once revealed, will enrich and transform the reader and his or her organisation. Regrettably, business life is not that simple. Rather, it is characterised by uncertainty and lack of precedent and complicated by the different wants, needs and motivations of people.

  • While there are many books on learning PHP and developing small applications with it, there is a serious lack of information on scaling PHP for large-scale, business-critical systems. Schlossnagle’s Advanced PHP Programming fills that void, demonstrating that PHP is ready for enterprise Web applications by showing the reader how to develop PHP-based applications for maximum performance, stability, and extensibility.

  • Simulation is an imitative process. It is used to study relationships between parameters that interact in a system. In some cases it may point out errors that cause a design to respond incorrectly. In other cases it permits optimization of a design for maximum performance or economy of operation or construction. In still other situations, the system may be so complex that simulation is the only way that variables affecting the design, and their interaction with each other, can be controlled and studied. In order to imitate the behavior of a product or system, simulation employs models.

  • When computing the performance of a vehicle in longitudinal motion (maximum speed, gradeability, fuel consumption, braking, etc.), the vehicle is modelled as a rigid body, or in an even simpler way, as a point mass. The presence of suspensions and the compliance of tires are then neglected and motion is described by a single equation, the equilibrium equation in the longitudinal direction. If the x-axis is assumed to be parallel to the ground, the longitudinal equilibrium equation reduces to m¨ = x ∀i ...
