A new texture analysis approach

A new texture analysis approach by using Gibbs random field model is discussed. A parameter vector is defined in order to compute potentials of textures. It is found that texture features can be provided by its corresponding parameter vector, and the vector can be estimated in terms of maximum potential. Conclusions can be inferred that this new method based on the maximum potential is valid. Supported by the National Natural Science Foundation of China Zhang Zhan: born in 1971, Ph.

The Use of Soft Systems Methodology to Enhance Group Creativity

Soft Systems Methodology is especially useful in diagnosing and addressing organizational problems and designing new systems in cultures that are characterised by pluralistic views and values. This paper demonstrates how SSM workshops in a large government agency resulted in a high level of creativity. SSM is then proposed as a methodology that could enhance group creativity in organizational design contexts.     

铬铁矿的分子动力学势能参数反演

导出一组对铬铁矿及其高压相、分解产物都适用的Buckingham势能参数,用于铬铁矿高压相变、分解以及高压相卸压降温过程的分子动力学模拟.首先,利用密度泛函理论(DFT)计算获得铬铁矿、钙铁相、钙钛相、FeO和Cr2O3不同体积时的结构和总能量.再根据晶格能与总能量之间的关系,由DFT所得结构和总能量,列出势能参数所满足方程组.应用遗传算法这一全局优化算法获得势能参数.为检验所得势能参数的正确性,将其用于分子动力学计算,得出的5种晶体的晶格常数与实验和DFT结果分别差～2%和～1%,得出的5种晶体的V(p)关系与DFT拟合的状态方程曲线相吻合.     

The Knowledge Age or the Age of Ignorance and the Decline of Freedom?

Increasingly knowledge has become a determining factor in achieving life’s potential and is the currency of the age. Without access to Information an individuals’ knowledge base cannot be enriched and without knowledge the individual becomes increasingly powerless. Advances in technology have provided opportunities for some to add to their stock of knowledge but access to sources of information is uneven and can lead to social unrest. The availability of information is an important factor in managing change and empowering citizens. The question about information and power then becomes one of ownership or sovereignty of the information. If we are to create an open society then we need to ensure that there is open access to knowledge through flexible and intelligent information systems that are available for all. In this paper we consider if we are truly entering the knowledge age or the age of ignorance.
