A novel technique of batch process monitoring based on lifting wavelet and multi-way principal component analysis (LWMPCA) is developed in this paper. The proposed technique consists of a preprocessing unit based on lifting wavelets transform in combination with MPCA. The superiority of the proposed method is illustrated by applying it to the simulation benchmark of fed-batch penicillin fermentation...
It is important for most oil companies to focus on the core assets which are oil and gas reserves so as to avoid risk posed by some factors such as oil prices and costs, etc. This paper will set up a model related to investment in upstream business based on system dynamics principles and predict the size and structure of investment in upstream business with computer simulation method. It demonstrates...
Ontology learning is a technology. Ontology learning can be used to establish ontology automatically or semi-automatically by introducing the ontology engineering and machine learning technology and many other sciences and technologies. The ontology learning technology which is proposed in our paper is to reduce the time of building an entire ontology. Our paper presents an Ontology Learning model...
Following problems have been found in traditional learning material management model based on courseware: common redundancy, the overlapped and desultory construction of the learning materials, and hardly adaptive to the diversity of the learning objectives and teaching methodologies. In the paper, a material-framework-objective model was proposed to improve the efficiency and quality of learning...
Traditional learning material management model based on courseware caused many problems includes common redundancy, the overlapped and desultory construction of the learning materials, and hardly adaptive to the diversity of the learning objectives and teaching methodologies.
