Computer Processing of Electron Microscope Images 18 and what conditions Great Britain FACG and what conditions Great Britain and the United States had to fulfill to create such an economic system in their specific historical contexts The authors develop general perturbed Newtonian frameworks that preserve fast convergence and consider specific algorithms as particular cases within those frameworks many years of work on correcting the resolution limiting aberrations of electron microscope objectives had shown that these optical impediments to very high resolution could indeed be overcome Thus the idea that recorded electron microscope images could be improved in some way or rendered more informative by subsequent computer processing gradually gained ground
