Applications of new technology in power substations
The authors describe the applications of some of the more modern technologies to instrument designed specifically to operate in utility substation environments. Particular emphasis is placed on the use of CMOS logic, processor, and memory circuits, high-density flexible magnetic disk media, and high-capacity Winchester technology storage devices. The operating history of a number of units over a five-year period is reported, as well as the steps taken to protect these devices in a hostile environment. In addition, areas requiring specific improvement and adaptation are noted.<<ETX>>
Microprocessor-based substation control
Abstract This paper describes a new approach to automating power substations. The current methods involved in the operation and control of substations are discussed and the basic functions involved are identified. The concept of integrating all these functions into one microprocessor-based control system is developed. The integrated microprocessor design presented in this paper eliminates the need for the presently used local controllers and other devices, leading to a cost-effective and highly reliable central substation controller.
Chapter 1 – Nanotechnology: A Toolkit for Cell Behavior
Tissue engineering seeks to effectively manipulate cellular populations to improve the function of damaged or diseased tissues and organs. Many techniques can affect cell behavior; however, in order to maintain desirable function, scientists and engineers design solutions that are as biomimetic as possible. True biomimeticity is very challenging without the incorporation of nanotechnology. Since cells in human tissues are surrounded by a 3D hierarchical tissue extracellular matrix containing numerous nano components, a revolutionary change in tissue engineering is to explore biomimetic nanobiomaterials and advanced 3D nano/microfabrication techniques for creating novel tissue constructs and regulating cell behavior. This chapter will provide an overview of recent nanotechnology in tissue engineering applications. We will put special emphasis on integrating cutting-edge 3D nano/microfabrication techniques with nanobiomaterials for complex tissue and organ regeneration.
