Normal Distribution Normal distribution is a statistics‚ which have been widely applied of all mathematical concepts‚ among large number of statisticians. Abraham de Moivre‚ an 18th century statistician and consultant to gamblers‚ noticed that as the number of events (N) increased‚ the distribution approached‚ forming a very smooth curve. He insisted that a new discovery of a mathematical expression for this curve could lead to an easier way to find solutions to

DISTRIBUTION AUTOMATION Abstract— This White Paper on‚ “Power systems” addresses the working process‚ benefits and challenges of implementing Distribution Automation in electrical power distribution sector. The demand for electrical energy is increasing every day. Today over 24% of total electrical energy generated in India is lost in transmission (6%) and distribution (18%). The electrical power deficit in country is currently about 18%. Therefore reduction in distribution

The Poisson distribution is a discrete distribution. It is often used as a model for the number of events (such as the number of telephone calls at a business‚ number of customers in waiting lines‚ number of defects in a given surface area‚ airplane arrivals‚ or the number of accidents at an intersection) in a specific time period. It is also useful in ecological studies‚ e.g.‚ to model the number of prairie dogs found in a square mile of prairie. The major difference between Poisson and Binomial
