Lexical Semantics and Knowledge Representation in Multilingual Text Generation develops the means for systematically deriving a set of paraphrases from the same underlying representation with the emphasis on events and verb meaning. Lexical Semantics and Knowledge Representation in Multilingual Text Generation provides detailed insights into designing the representations and organizing the generation process.Furthermore, the same mapping mechanism is used to achieve multilingual generation: English and German output are produced in parallel, on the basis of an adequate division between language-neutral and language-specific (lexical and grammatical) knowledge.

As process geometries have shrunk into the deep-submicron region, the logic capacity of FPGAs has greatly increased, making FPGAs a viable implementation alternative for larger and larger designs. transistor-level) design of the FPGA.

There is also another important reason for writing this book. This is but a tiny fraction of the books dedicated to the finite element method in other subjects such as Civil Engineering.The motivation to write this book comes from the need to redress this imbalance. At present, there are only a handful of other books that describe it in relation to Electrical Engineering topics [3], let alone charged particle optics.

Stochastically-Based Semantic Analysis investigates the problem of automatic natural language understanding in a spoken language dialog system.Stochastically-Based Semantic Analysis will be of most interest to researchers in artificial intelligence, especially those in natural language processing, computational linguistics, and speech recognition. The focus is on the design of a stochastic parser and its evaluation with respect to a conventional rule-based method. Stochastically-Based Semantic Analysis.

It includes the theory of functional systems in fuzzy logic, providing an explanation of what can be represented, and how, by formulas of fuzzy logic calculi. This book presents fuzzy logic as the mathematical theory of vagueness as well as the theory of commonsense human reasoning, based on the use of natural language, the distinguishing feature of which is the vagueness of its semantics. The book is based on logical formalism demonstrating that fuzzy logic is a well-developed logical theory.

Design has generally focused on new architectures with little attention being paid to optimization. Oversampled A/D converters have become very popular in recent years.

To meet these needs it is necessary to have a well designed maritime surveillance and control system capable of tracking ships and providing other types of information required by a variety of user groups ranging from port authorities, shipping companies, marine exchanges to governments and the military. Principles of Integrated Maritime Surveillance Systems is therefore essential to a variety of user groups ranging from port authorities to shipping companies and marine exchanges as well as civil governments and the military.Principles of Integrated Maritime Surveillance Systems Principles of Integrated Maritime Surveillance Systems will be of vital interest to anyone responsible for the design, implementation or provision of a well designed maritime surveillance and control system capable of tracking ships and providing navigational and other types of information required for safe navigation and efficient commercial operation..

Starting from established approaches, the book covers various object models and discusses their properties. This constraint store serves as a communication medium between concurrent threads of control and as a vehicle for their synchronization. Its central contribution is the notion of partial information provided by a shared constraint store. Objects for Concurrent Constraint Programming analyzes the possibility of supporting object-oriented programming in ccp.

More advanced systems utilize dedicated hardware to speed up the processing stage. This chapter presents a set of introductory material, which in addition to providing a general view on the topic, highlights the importance of research in this area. Biological visual systems have evolved over millions of years, and each specie has developed a specialized visual system tailored for the essential tasks of survival, such as catching a prey, or escaping a predator.

PIVOT, the fully automated system implementing these techniques, is quantitatively evaluated on 83 images covering 18 test scenes, and compared to three existing systems for building extraction. PIVOT's performance illustrates the implications of a clearly articulated set of philosophical principles, taking a significant step towards automatic detection and delineation of 3D objects in real-world environments. Geometric Constraints for Object Detection and Delineation Many of these problem domains do not have strong constraints on object shape or scene content, presenting serious obstacles for the development of robust object detection and delineation techniques. The results highlight the performance improvements possible with rigorous photogrammetric camera modeling, primitive-based object representations, and geometric constraints derived from their combination.

The resulting Tetrobot system consists of fundamental components which may be mechanically reassembled into any modular configuration, and the control architecture will provide position control of the resulting structure.. Tetrobot arms, platforms, and walking machines have been built and controlled in a variety of motion and loading conditions.

In the United States, the FCC propelled the wireless era from infancy to mainstream with a $7.S.

Intelligent Image Databases: Towards Advanced Image Retrieval addresses the image feature selection issue in developing content-based image retrieval systems. A major challenge in building a region-based image retrieval system is that prominent regions are rather difficult to capture in an accurate and error-free condition, particularly those in images of real-world scenes.

However, for high accuracy and/or higher processing complexity, not only the relative overhead cost of the front-end and back-end converters will diminish but also the implementation of the processing core in digital VLSI will benefit more of technology scaling to achieve higher density of integration.

This volume is an invaluable resource for researchers, practitioners, and students working in information retrieval and databases. While this text focuses on algorithms and not on commercial product per se, the basic strategies used by many commercial products are described. Information Retrieval: Algorithms and Heuristics is a comprehensive introduction to the study of information retrieval covering both effectiveness and run-time performance.

Deadline Scheduling for Real-Time Systems Also, adding to the complexity is the fact that a variety of algorithms have been designed for different combinations of these considerations. This includes cyclic scheduling, rate monotonic scheduling and fixed schedules created by off-line scheduling techniques such as dynamic programming, heuristic search, and simulated annealing. There exists a wealth of literature on EDF-based scheduling with many extensions to deal with sophisticated issues such as precedence constraints, resource requirements, system overload, multi-processors, and distributed systems.
