E-learning is popularized so fast and Collaborative Learning (CL) becomes so important an instructional strategy. There are huge Group Session (GS) texts needed to be analyzed to evaluate CL, thus the automatic or semi-automatic methods of analyzing the GS texts become very important. In this paper we present a method called Interaction Analysis depended on Knowledge Extraction (IAKE) to analyz...

We discuss various properties of the ground state of a Bose-condensed dilute gas confined by an external potential. We devote particular attention to the role played by the interaction in determining the kinetic energy of the system and the aspect ratio of the velocity distribution. The structure of the wave function near the classical turning point is discussed and the drawback of the Thomas-F...

Mark Duffy produced a complete set of grinding data on pilot-scale tower mill. Here these are analyzed in terms kinetics. The results show that the can be fitted with simple first-order breakage model, which is not normally observed any system, including other types machines such as tumbling ball mills and rod mills. model has only two parameters, making it possible to determine parameters usin...
