This paper describes the plant modeling research based on improved 3D L-system and quaternion. It first introduces the original 3D L-system and how to implement it, then brings forward the improved modeling method of 3D L-system by specifying the growth vector and azimuth vector and applies the quaternion based computer algorithm in it, in the end generates some 3D plant models of sympodia and uniaxiality based on the improved method and algorithm.

A novel platform system for gait analysis was developed, with its two main parts: force platform and pressure platform, it can offer complete components of pressures in walking, including vertical pressure, shear forces, pressure distribution and COP (centre of pressure) with reliable result. System configuration was introduced as an important part, and gait model was established. Some examples of application were also reported.

Inspired by the transmission of seeds in nature, an evolutionary algorithm, seed optimization algorithm (SOA), is proposed. The algorithm is designed by simulating the self-adaptive phenomena of plant and it can be used to resolve complex optimization problems with the evolution of plant. The global convergence analysis of SOA is made by using the Solis and Wets'research results. Finally, SOA is applied to three function optimization problems and compared with particle swarm optimization (PSO) algorithm. The experimental results show that SOA has stable and robust behaviour and it can be used as a promising alternative to existing optimization methods for engineering design.
