Abstract As the second stage of CEPC-SPPC project, SPPC (Super Proton-Proton Collider) aims at exploring new physics beyond Standard Model. The key design goal for accelerator complex is to reach 75 TeV in center mass energy with a circumference 100 km collider and an injector chain four accelerators cascade support collider. important part conceptual study, longitudinal beam dynamics was studi...

this paper describes optimization method that combines the plackett-burman design, a factorial design and the response surface method, which were used to optimize the medium for the production of l-asparaginase by serratia marcescens sb08. four medium factors, from out of 11 medium factors, were screened by plackett-burman design experiments and subsequent optimization process to find out the o...

Antenna current optimization is a tool that offers many possibilities in antenna technology. Optimal currents are determined in the antenna design region and used for physical understanding, as a priori estimates of the possibilities to design antennas, physical bounds, and as figures of merits for antenna designs. Antenna current optimization is particularly useful for small antennas and anten...
