Abstract : There are several methods to cover the costs of a transmission system and distribution networks. These methods are divided into either incremental or marginal approaches, which can be either long-term or short-term. The main difference between the incremental and marginal approach is how to calculate the cost of using the network. In the incremental approach, simulation and in the ma...

any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
