The Expert program is a part of larger project (Intelligent Tutoring System) and plays a role of an assistant and disputant with the system user. The authors of the article analyse algorithm of this module and discuss various Java technologies for preparation of application.

Content-based image retrieval is an important area of research involving techniques of image processing, information retrieval, and data mining. Mathematical morphology is a powerful set of tools in image processing and normally used for filtering, shape description etc.. Sequence data mining and clustering are the popular data mining techniques that are successfully applied to varieties of app...

Data mining faces multiple defies, with improving its results through the use of domain knowledge at the top. The advent of domain driven data mining brings new techniques to use that knowledge. Educational data mining is a favored domain to explore such tools, both due to the advances in the area and the existence of domain knowledge. In this work, we propose a new methodology for anticipating...

INTRODUCTION The amount of data being generated and stored is growing exponentially, due in large part to the continuing advances in computer technology. This presents tremendous opportunities for those who can unlock the information embedded within this data, but also introduces new challenges. In this chapter we discuss how the modern field of data mining can be used to extract useful knowled...

in the present study, an investigation was carried out on parvadeh coal mine in tabas, iran, to survey the effect of fractures on unusual methane gas emission in coal mines. this coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. gas concentration monitoring programs were carried out at the mine s...

The supervision of people in special circumstances, having as their purpose detecting risk situations, is an area which has many applications. In this context we are interested, in this paper, the problems of driver drowsiness detection based on video analysis. We describe a new approach to detect reduced alertness automatically, to prevent the driver. Unlike many other works, our noninvasively...

The paper analyzes knowledge mining of the test case System. Widespread use of test case systems and explosive growth of databases require traditional manual data analysis to be coupled with methods for efficient computer-assisted analysis It is very important for us to utilize this kind of information effectively. Today, the design of test case with enhanced reliability is a real challenge as ...

Abstract Background The mining-induced stress in the surrounding rock after coal seam mining is primary cause of damage and failure area. However, magnitude direction field induced by overburden strata during excavation process deep adjacent seams are not yet clear, it difficult to determine how working faces interact with each other. Results In this study, a large-scale numerical model was bui...
