  • Communication happens in the form of signals. Signals are transmission of energy (mechanical, electrical or light) through appropriate media. A signal that is constant and changed once conveys single information. The more changes in the signal, the more information that the signal can convey. For example, a push can mean one thing and removing it can mean another thing.

  • Rawson and Tupper's Basic Ship Theory, first published in 1968, is widely known as the standard introductory text for naval architecture students, as well as being a useful reference for the more experienced designer. The fifth edition continues to provide a balance between theory and practice. Volume 2 expands on the material in Volume 1, covering the dynamics behaviour of marine vehicles, hydrodynamics, manoeuvrability and seakeeping. It concludes with some case studies of particular ship types and a discussion of maritime design.

  • In almost all areas of daily life the demands on the communications infrastructure increased dramatically. With regard to the volume of data that has to be transmitted, no matter whether we are dealing with public or private networks, industrial fields or automobiles, needs will continue to rise. Consequently, the demands on the bandwidth of communications systems will continue to increase since more and more video data streams with high picture quality (IP TV), in addition to telephone and data circuits, will be transmitted.

  •  This guide publication is a reference containing fundamental engineering guidelines and basic recommendations on structural and electrical aspects of transmission line design, as well as explanations and illustrations. The many cross-references and examples should be of great benefit to engineers performing design work for RUS borrower transmission lines. The guide should be particularly helpful to relatively inexperienced engineers beginning their careers in transmission line design.

  • More complex networking services in Red Hat Linux require more advanced administration methods. While graphical tools such as Network Configuration (via the redhat-config-network command) are available to assist in configuring all aspects of Linux networking, the best way to learn networking is by practicing with the key command line utilities and associated configuration files.

  • ATM is a packet-switched technology based on a 53-byte packet called a cell. Each cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length cell reduces delay and jitter, allowing time sensitive information such as voice and video to be transported along with data. There are various transmission media and rates available with bandwidth measured in megabits to gigabits.

  • Network management is the poor cousin of network design and implementation. All too often it is treated as an inconvenience by equipment manufacturers, or forgotten entirely. But the ability to manage network devices is fundamental to their utility, and a successful and functional network can only be built from equipment that can be easily managed and operated. Management refers to the ability to confi gure, control, operate, and diagnose equipment. Of course, no vendor ships devices that cannot be managed, but typically each is operated and controlled in a different way.
