Managing risk in large complex systems

Article Abstract:

Risk management for large industrial or research systems involves thousands of components and subsystems that interact in complex ways that are sometimes unforeseen. Several major disasters are examined including the Bhopal, India disaster, the space shuttle Challenger crash and the Chernobyl nuclear disaster. The analysis begins with a look at chief methods used to assess and evaluate the risks involved with large systems. Questions raised include what risks are involved in pushing systems beyond their intended life, such as elderly aircraft; what external risks affect large systems, such as natural disasters, war or sabotage; how can the range of possible consequences be anticipated and prepared for, how can management and engineers come to agreement on failure prediction, and what are the risks of operating a system from a remote site with inadequate control.

U.S. science and technology museums

Article Abstract:

A survey report on the visitors of the science museums in the United States reveals that the principal evaluation of the visiting kids and their engineering parents is 'fun.' The exhibits that can be manipulated by the own hand have got best response from the kids as well as from their parents. Exhibits preferred both by boys and girls are produced in the museums. The power of grasping things is not equal for every boys and girls. It is parent's duty to motivate their children towards science and technology.

Remote sensing

Article Abstract:

Remote sensing satellites circling the earth in low sun synchronous polar orbits furnish good images using multispectral sensors and radars. It is possible to know the nature, size and thermal status of appreciably small features. The data is extensively used in cartography in the zoning, use and tax accounts of lands, in the warming of natural hazards and in military exercises and logistics.
