Alfred Hupe drawback of a rocket vehicle: to be forced to carry all necessary reaction mass onboard. The more energetic is the mission transfer the more massive is the spaceship. Future space missions are expected to increase in number, purpose, and energy. It should be clear that any new good method for pract

Hans Wesselinge deformation of the frame is described by a generalized plane stress state with an elasticity modulus scaled by the thickness. This constrained nonlinear optimization problem is solved by sequential quadratic programming (SQP) which requires gradients of the objective and the constraints with respe

Hans Peter Bergner.Introduces a new technique for examining short time-scale sThis thesis brings together the various techniques of X-ray spectral analysis in order to examine the properties of black holes that vary in mass by several orders of magnitude. In all these systems it is widely accepted that the X-ray emis
