This paper addresses the noise-minimal trajectory optimization problem for a specific type of aircraft: rotorcraft. It relies on realistic noise footprint computation software provided by industry that is black-box. Locally optimal trajectories are computed through tailored solution approach based Mesh-Adaptive Direct Search algorithm. We propose multiple surrogates defined according to our kno...

Objectives: The purpose of this research work was to formulate and systemically evaluate in vitro performances polymeric microspheres nifedipine. Methods: Nifedipine containing two polymers, poloxamer 407 carbopol 934, were prepared by single emulsion cross-linking technique. Glutaraldehyde selected as the agent. A Box–Behnken design employed study effect independent variables, polymer concentr...

A new implementation scheme of AES (Advanced Encryption Standard) is proposed in this paper. The LUT based design of S-box consumes almost 75% of power. Instead of using LUT based S-box, composite field S-box design is used. That can reduce the amount of power consumption. The values of s-box are known to everyone. By masking the each value in the s-box by another masking function increase the ...
