The more integrated a plant is, the less controllable (and by implication safe) it is, and the harder it is to start the plant up. ![]() Setting in stone the results of such an analysis early in the design process as the foundation of design is very unlikely to be optimal. Network analysis is all very clever, but it can only do one thing. When you have studied this chapter you should be able to calculate the current, voltage and power in any element of most commonly encountered d.c. circuits only to begin with because they are a little simpler mathematically and the concepts are that much easier to grasp. and d.c, but it is convenient to consider d.c. These theorems, which are introduced in this chapter, are applicable to linear circuits, both a.c. However, a number of techniques have been developed, in the form of network theorems, for simplifying the analysis in the case of more complicated circuits. ![]() ![]() The two basic laws for circuit analysis are Kirchhoff's current law (KCL), sometimes referred to as the first law and Kirchhoff's voltage law (KVL), sometimes called the second law.

This translates to the ways disaster risk can be reduced by understanding who is missed, ways to more effectively engage with people at risk along with appropriate avenues to reach them, and what kinds of information are needed to be most useful for recovery, adaptation, and reducing risk. Social network analysis was used to inform gaps in the types and locations of stakeholders and networks engaged with and involved in the Third National Climate Assessment and that were missed, thus informing ways to improve future engagement, reach, and flow of information and, in turn, improve understanding of stakeholders’ informational needs and improve the usefulness and usability of information products ( Cloyd, Moser, Maibach, Maldonado, & Chen, 2015). For example, with the support of partners at Michigan State University, the United States National Climate Assessment conducted a preliminary social network analysis to diagram the interactions between people and organizations engaged by the National Climate Assessment and show how the network of stakeholders changed over the course of the Third National Climate Assessment (2010–14). Network analysis can inform institutional and interagency guidelines for developing practical ways to ensure effective flow of information and resources. Maldonado, in Social Network Analysis of Disaster Response, Recovery, and Adaptation, 2017 Effective Flow of Information and Resources to Reduce Disaster Risk The Practical and Policy Relevance of Social Network Analysis for Disaster Response, Recovery, and Adaptation One might say that a billion cars have traveled down a particular section of motorway since it was built, but if he/she were planning a journey down that motorway, he or she would want to know the flow of cars per hour through that section. Simply being able to say that a large number of electrons had flowed past a given point is not in it very helpful. One could say that 1 C of charge had flowed between one point and another, which would be equivalent to saying that approximately 6,240,000,000,000,000,000 electrons had passed, but much handier. An electron is very small, and does not have much of a charge, so one needs a more practical unit for defining charge. Electrons are negative and positrons are positive, but while electrons are stable in the universe, positrons encounter an electron almost immediately after production, resulting in mutual annihilation and a pair of 511 keV gamma rays. Unlike charges attract, and like charges repel. Charged objects come in two forms-negative and positive. Charged objects are attracted to other charged particles or objects.
