Hohmann Transfer via Constrained Optimization
In the first part of this paper, inspired by the geometric method of Jean-Pierre Marec, we consider the two-impulse Hohmann transfer problem between two coplanar circular orbits as a constrained nonlinear programming problem. By using the Kuhn-Tucker theorem, we analytically prove the global optimality of the Hohmann transfer. Two sets of feasible solutions are found, one of which corresponding...
متن کاملMemoriam.
George W. Housner, Carl F Braun Professor of Engineering, emeritus, died after a short illness on 10 November 2008, just a few weeks before his 98th birthday. He was in the retirement home in Pasadena where he had lived for several years. For all of us who knew George, this marked the end of an era.

متن کاملIn Memoriam: Mark Everingham
MARK EVERINGHAM was a brilliant colleague. You may have been aware of him at conferences where he asked penetrating questions that could crystallize a key aspect of a paper. In conversation with him you might have been stunned by a new connection he made between areas of research or to a crucial related work. These questions and observations were a reflection of his very broad knowledge and dee...
متن کاملSteven Hsiao: In Memoriam
Steven Hsiao Hopkins neuroscientist Steven Hsiao, one of the world’s leading experts on the neural basis of touch, passed away on June 16, 2014 at the age of 59 from lung cancer. Steve, the heir of an eminent line of sensory neuroscientists that included Vernon B. Mouncastle and Kenneth O. Johnson, sought to understand the neural code: how do spatio-temporal patterns of activity along the neura...
