Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec

Sensing and planning are at the core of robot motion. Traditionally, mobile robots have been used for performing various tasks with a general-purpose processor on-board. This book grew out of our research enquiry into alternate architectures for sensor-based robot motion. It describes our research starting early 2002 with the objectives of obtaining a time, space and energy-efficient solution for processing sensor data for various robotic tasks. New algorithms and architectures have been developed for exploration and other aspects of robot motion. The research has also resulted in design and fabrication of an FPGA-based mobile robot equipped with ultrasonic sensors. Numerous experiments with the FPGA-based mobile robot have also been performed and they confirm the efficacy of the alternate architecture.

Universal.Data.Access.Components 2.50 Universal Data Access Components (UniDAC) is a library of components that provides direct access to most popular database servers from Delphi, Delphi for .NET and, C++Builder. UniDAC can work with such servers as Oracle, Microsoft SQL Server, MySQL, Interbase, Firebird. The UniDAC library is designed to help programmers develop faster and cleaner cross-database applications. UniDAC is a complete replacement for such standard universal technology as dbExpress. UniDAC is a handy in use and efficient data access solution bringing into play many features specific to each server.

Faster, better, and cheaper is the name of the game for machine designers. Demands for higherperformance and increasingly efficient machines designed in a shorter amount of time with smaller design teams are challenging machine designers to improve their machine design processes.

The Fortran 90 Handbook is a definitive and comprehensive guide to Fortran 90 and its use. Fortran 90, the latest standard version of Fortran, has many excellent new features that will assist the programmer in writing efficient, portable, and maintainable programs. The Fortran 90 Handbook is an informal description of Fortran 90, developed to provide not only a readable explanation of features, but also some rationale for the inclusion of features and their use. In addition, “models” give the reader better insight as to why things are done as they are in the language.

Collection of key-value pairs. TDictionary represents a generic collection of key-value pairs. This class provides a mapping from a collection of keys to a collection of values. When you create a TDictionary object, you can specify various combinations of initial capacity, equality operation, and initial content. You can add a key that is associated with a corresponding value with the Add or AddOrSetValue methods. You can remove entries with Remove or Clear, which removes all key-value pairs. Adding or removing a key-value pair and looking up a key are efficient, close to O(1), because keys are hashed. A key must not be nil (though a value may be nil) and there must be an equality comparison operation for keys. You can test for the presence or keys and values with the TryGetValue, ContainsKey and ContainsValue methods. The Items property lists all Count dictionary entries. You can also set and get values by indexing the Items property. Setting the value this way overwrites any existing value. The class TObjectDictionary inherits from TDictionary and provides an automatic mechanism for freeing objects removed from dictionary entries.
