Inferences for One Population Standard Deviation The Standard deviation is a measure of the variation (or spread) of a data set. For a variable x‚ the standard deviation of all possible observations for the entire population is called the population standard deviation or standard deviation of the variable x. It is denoted σx or‚ when no confusion will arise‚ simply σ. Suppose that we want to obtain information about a population standard deviation. If the population is small‚ we can often determine

into the recent trends in power transmission engineering‚ FACTS and HVDC. The first part of our presentation starts with a quick idea of FACTS. FACTS is defined as a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase the power transfer capability. This paper also deals with the basic concept involved in the usage of FACT controllers which are capable of controlling up to three system
