PHYSICAL MATHEMATICS SEMINAR TITLE: OPTIMAL MECHANISMS SPEAKER: MICHAEL P. BRENNER Division of Engineering and Applied Sciences Harvard University ABSTRACT: The talk will describe some recent theoretical and experimental work on the optimal design of mechanisms. Although there is a long history of mathematical approaches to optimal design problems, most of the work focuses on designing a single state of a system to optimize some target function. We will describe several examples involving the design of a mechanism: the examples will include (a) the optimal design of a mems relay switch; (b) the optimal design of the actuation mechanism for the switch; and (c) finding the shape of a nozzle with fixed cross sectional area which ejects the smallest sized droplet under adiabatic forcing.
