Cooler is the key device of rotary calcining kiln to produced limestone. Through design processes, better heat exchange can be obtained. According to the structural features and working principles of rotary calcining kiln, the finite element model of cooler is built. Then the convection heat transfer coefficient is calculated on the theory of heat transfer. On the simulation analysis of the heat transfer...
Collaborative filtering, which plays an important role in making personalized recommendation, is one of the most traditional and effective recommendation algorithms. However, this algorithm suffers the sparse user rating record matrix problem which would result in poor recommendation precision. A usual approach to alleviate this problem is filling empty values with user average rating value. This...
With the development of our society, the languages are also constantly evolving. In order to master the word situation of modern Uyghur language, I regard modern Uyghur language data analysis technology as the study method, the standard Uyghur language textbooks frequency list of elementary and junior high school as the object of study, we can make a study of the word situation survey. In this article,...
In recent years, there are more and more Open APIs available on the Internet that can be invoked by independent users for their innovative applications. With the development of cloud computing, the number of Open APIs in clouds is also increasing. With the number increasing of functionally-equivalent Open APIs in the cloud, optimal API selection is becoming more and more important. In this paper,...
In order to solve the problems of difficulty to determine the number of partitions and rule redundancy in neuro-fuzzy system modeling, this paper presents a new approach based on DENCLUE using a dynamic threshold and similar rules merging (DDTSRM). By introducing DDT, which uses a dynamic threshold rather than a global one in merging density-attractors in DENCLUE, our approach is good at determining...
