Abstract F-theory/heterotic duality is formulated in the stable degeneration limit of a K3 fibration on the F-theory side.In this note, we analyze the structure of the stable degeneration limit.We discuss whether stable degeneration exists for pairs of rational elliptic surfaces.We demonstrate that, when two rational elliptic surfaces have an ident
The works of art are priceless going by the quality of works exhibited by an artist.The artist tends to describe a particular scene near to the natural object in question.In the 15th and 16th centuries , France relayed on the impressionists who graduated from workshops and schools of apprentice in the likes of Gauguin, Work Shirts Monet, Manet, Deg
The growth in renewable power generation and more strict local regulations regarding power quality indices will make it necessary to use energy storage systems with renewable power plants Baby Transport in the near future.The capacity of storage systems can be determined using different methods most of which can be divided into either deterministic
A new model has been defined that enables the 50"x60" estimation of the lethal radius (radius of efficiency) of HE (High Explosive) artillery projectiles against human targets.The model is made of several modules: CAD (Computer Aided Design) modeling, fragment mass distribution estimation, fragment initial velocity prediction, fragment trajectory c
