Purpose To meet the government standard basic criterion GB18871-2002 for radiation protection and safety,and to optimize the design of the shielding protection of medical linear accelerator.
The topics discussed include GA design GA improvement, optimal designof parameters of classical controller, simultaneous optimal design of the structure and theparameters of digital controller and emulation of on-line design.
Along the manual initial horizontal alignment, using the combination of generalized reduced gradient and gradient projection techniques by means of DTM and computer, the optimization of both vertical and horizontal alignments can be realized.
Stress concentration reduction in a finite plate with a hole is accomplished by introducing optimally size and placed auxiliary holes with simultaneous shape optimization of both central and auxiliary holes.
A simultaneous optimization of resolution, efficiency and migration times of enkephalin-related peptides in micellar electrokinetic capillary chromatography (MEKC) was performed.
This paper presents a new method for the optimization of alignments in rail- way design. A recurrence relation model is developed to represent the railway line in space. Along the manual initial horizontal alignment, using the combination of generalized reduced gradient and gradient projection techniques by means of DTM and computer, the optimization of both vertical and horizontal alignments can be realized. Several examples are worked out with satisfactory results, sho- wing the feasibility of the method.
Based on the theory of engineering optimization,an approximative for- mula for the cost of the piping and its insulation is presented in this paper.A rea- sonable procedure is also put forward for simultaneous optimal design of the pipe diameter and the insulation thickness.The calculation results have been analyzed.
The writer identification of text-independent is a subject in the area of image processing and pattern recognition,which has a wide range of potential applications. A feed-forward neural network method is proposed and applied to writer identification.The two problems that feature extraction from gray image and design of feed-forward neural network are discussed. Eighteen gray features of three sorts are extracted from a person's handwriting image. And a new genetic algorithm is proposed to optimize the stru...
