  •  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.

  • In this laboratory experiment, you will use SPICE to study sinusoidal waves on lossless transmission lines. Our goal is for you to become familiar with the basic behavior of waves reflecting from loads in transmission lines, and compare the simulations with numeric calculations and the Smith Chart.

  • This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location.

  • There are many occasions when data need to be transmitted over a voice communication network. Many people use a computer to connect to their Internet Service Provider via the telephone lines to transmit and receive data, check their email, surf the Web, etc. Telephone networks were originally built for human speech, not for computer data and is unsuitable for digital communication in its raw form.

  • A bit (binary digit) is the smallest unit of information • N = 2n where N is the number of representations and n is the number of bits (ex. ASCII, Unicode, PCM code etc.) • Data communications transfer information using codes that are transmitted as signals (either analog or digital) • In general, analog lines provide a slow service that contains high error rates.

  • Power quality is an important measure of fitness of electricity networks. With increasing renewable energy generations and usage of power electronics converters, it is important to investigate how these developments will have an impact to existing and future electricity networks. This book hence provides readers with an update of power quality issues in all sections of the network, namely, generation, transmission, distribution and end user, and discusses some practical solutions.

  • 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.

  • Temperature measurement and control are vital in many industrial processes. Accurate control of the temperature is essential in nearly all chemical processes. In some applications, an accuracy of around 5-10~ may be acceptable. There are also some industrial applications which require better than 4-1 ~ accuracy.

  • The transportation system is a network of highways, trails, railroads, airports, transmission lines, pipelines, canals, and waterways set in the landscape. The goal of the transportation designer is to fit the highway or other facility into the adjacent landscape in a way that is complementary to, and enhances, the existing landscape. Achieving this goal requires consideration of natural, ecological, aesthetic, economic, and social influences related to that landscape.
