amp DARTEL Ged Ridgway London With thanks to John Ashburner and the FIL Methods Group Aims of computational neuroanatomy Many interesting and clinically important questions might relate to the shape or local size of regions of the brain. Our method optimizes the inertia tensor of an input model by changing its mass distribution allowing long and stable spins even for complex asymmetric shapes Abstract Spinning tops and yoyos have long fascinated cultures around the world with their Our method optimizes the inertia tensor of an input model by changing its mass distribution allowing long and stable spins even for complex asymmetric shapes Abstract Spinning tops and yoyos have long fascinated cultures around the world with their ethzch Victor Shoup IBM Zurich Research Laboratory Saumerstr 4 8803 Ruschlikon Switzerland shozurichibmcom May 1998 Abstract A new public key cryptosystem is proposed and analyzed The scheme is quite practical and is provably secure against adaptive -Based .
