Material selection for optimum design of MEMS pressure sensors

open access: yesMicrosystem Technologies, 2019
Choice of the most suitable material out of the universe of engineering materials available to the designers is a complex task. It often requires a compromise, involving conflicts between different design objectives.

Optimum Experimental Designs

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1959
Summary After some introductory remarks, we discuss certain basic considerations such as the nonoptimality of the classical symmetric (balanced) designs for hypothesis testing, the optimality of designs invariant under an appropriate group of transformations, etc. In section 3 we discuss complete classes of designs, while in section 4 we

Aerodynamic shape optimization of a low drag fairing for small livestock trailers [PDF]

open access: yes, 2008
Small livestock trailers are commonly used to transport animals from farms to market within the United Kingdom. Due to the bluff nature of these vehicles there is great potential for reducing drag with a simple add-on fairing.
