Based on the maize ecophysiological characteristics, the maize developping process-based cooperative models including growth model, developmental phase models, water balance model and nitrogen balance model etc. was built combined with the basic data such as variety characteristics, weather data, soil level and cultivation management with the technology support of system engineering method, cro...

We derive for the Navier-Stokes equation an exact equation satisfied by the dissipation rate correlation function, 〈ǫ(~x+~r, t+ τ)ǫ(~x, t)〉. In the equal time limit, for the homogeneous, isotropic state of fullydeveloped turbulence, we show that the correlation function behaves as Ar1 +Br2 with μ1 = 2−ζ6 and μ2 = z ′′ 4−ζ4 for r in the inertial range; the ζ’s are exponents of velocity structure...

Many researches have been working on the protein folding problem from more than half century. Protein folding is indeed one of the major unsolved problems in science. In this work, we discuss a model for the simulation of protein conformations. This simple model is based on the idea of imposing few geometric requirements on chains of atoms representing the backbone of a protein conformation. Th...

This paper describes the design and empirical validation of three distinct pedagogical agent roles (Expert, Motivator, and Mentor) for college students within the MIMIC (Multiple Intelligent Mentors Instructing Collaboratively) agent-based research environment. The pedagogical agent roles were operationalized by image, animation, affect, voice, and dialogue and were developed in Poser 4 and imp...
