In this thesis, Particle Filter Methods are investigated in the context of moving targets tracking and the associated performance analysis. The application scope of this algorithm which is a particular case of Sequential Monte Carlo Method is far broader than tracking of moving targets. This algorithm can be used for mathematical calculations such as estimation of mathematical expectations, integrals, surface area of curves and many other mathematical calculations. In addition, it has applications in other branches of science like genetics. This algorithm is based on random sampling of a probability density function and resampling from the extracted samples. We change this algorithm in... 

The Droughts in various parts of the world cause a lot of economic and social damage every year. In fact, droughts are due to climate fluctuations that are inherent in the natural processes of meteorological and hydrological processes and reduce water resources; population growth; Of course population growth, exacerbates its consequences. Research as well as observations have shown that climate change also exacerbates extreme phenomena such as drought and flood. The population of Kabul city, the capital of Afghanistan, is increasing due to migration from other cities, and on the other hand, the flow of the river in the summer is minimized, which for some years leads to drought. In these...
