Optimization approach to define geometry (parameters) of radial matching section in RFQ accelerator is suggested. This approach gives wider opportunities to design of radial matching section because it does not have certain prescribed laws of variation of focusing strength along the section. INTRODUCTION Acceptance at the entrance of RFQ accelerator, as it is known, depends on time and rotates ...

This paper presents a linkage factors synthesis and multi-level optimization technique for bi-stable compliant mechanism. The linkage synthesis problem is modeled as multiple level factors and responses optimization problem with constraints. The bi-stable compliant mechanism is modeled as a crank slider mechanism using pseudo-rigid-body model (PRBM). The model exerts the large deflection of fle...

The Bi–In–Sn–Zn system is an important alloy system in lead-free soldering. Thermodynamic descriptions for the ternary systems Bi–In–Sn, Bi–In–Zn, Bi–Sn–Zn and In–Sn–Zn are optimized, using the CALPHAD method and combined to obtain a description of the quaternary Bi–In–Sn–Zn. All available experimental data from the literature are taken into consideration in the optimization. Calculated liquidi...

This paper presents a meta-objective optimization approach, called Bi-Goal Evolution (BiGE), to deal with multi-objective optimization problems with many objectives. In multi-objective optimization, it is generally observed that 1) the conflict between proximity and diversity requirements is aggravated with the increase of the number of objectives and 2) the Pareto dominance loses its effective...

Crude Oil Distillation Unit (CDU) is one of the most important separation installations in petroleum refinery industries. In this work, a Bi-level Surrogate column model Aided Constrained Optimization Design (Bi-SACOD) proposed for time-consuming objectives and constraints evolutionary optimization design CDUs. The main components Bi-SACOD include bi-level surrogate construction (Bi-SMC), manag...

Highly crystalline Bi3+-doped cadmium oxide (CdO) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. The reaction was carried out with cadmium nitrate (Cd(NO3)2.4H2O), bismuth nitrate (Bi(NO3)3.5H2O) and ethylene glycol (C2H6O2) reactan...
