The purpose of this paper is to research on the application of data warehouse model based on the integration of emerging technologies in business data mining. Single approaches of tackling business challenges did not effective in many reasons. In this research, we introduced and discussed a novel integration for tools and agents techniques and methodologies, which gives insight a best adaptation of business scanning system to the specific needs of the various businesses that allowing decision-makers to optimum decision outcomes. The experiment result shows the performance can be improved substantially. Copyright © 2016 American Scientific Publishers All rights reserved.

Principles and characteristics of setpoint overshoot method are illustrated. The proposed method has been developed for PID controller tuning of an unidentified process using closed loop experiments. It requires one closed-loop step setpoint response experiment using a proportional only controller, and it mainly uses information about the first peak (overshoot) which is very easy to identify. It was applied in turbine of power plant to tune the PI parameters of load control. The application results demonstrate the validity of the proposed method. © (2013) Trans Tech Publications, Switzerland.

CCD technology is used in production process of cultural products to detect flatness, which reduces the error formation probability. This paper proposes an image detection model for cultural production flatness measurement based on computer vision feature point matching algorithm. The method uses the pixel frequency sorting method to divide pixel level of collected images, so as to obtain high precision pixel characteristics as the basis for measuring the flatness for cultural products' structure, and extracts image features of cultural products and carries out matching process to establish an image detection model for flatness measurement. The experimental results show that the proposed algorithm greatly improves the accuracy of flatness measurement for cultural product structure. © (2014) Trans Tech Publications, Switzerland.

Wind power and other new energy connected to power grid bring new challenges to optimal operation of power systems. The stability of power grid mainly depends on primary frequency compensation and secondary frequency compensation of thermal power units. By analyzing the theory and practice of DEH and coordinated control system(CCS) of thermal power units, combined with the insufficient of actual primary frequency compensation and automatic power generation control (AGC) strategy response to frequency of accidents, the optimization of primary frequency compensation and AGC of thermal power unit's automatic control were offered. The practical application results show that the proposed control strategy can effectively control the thermal power units to achieve the stability of power grid frequency. © (2013) Trans Tech Publications, Switzerland.

The mechanism of NOx formation in coal combustion, NOx control methods and key DeNOx technologies is to be introduced. Denitrification is very significant for saving energy and carbon sources. By analysis of NOx production mechanism, the principles of controlling NOx production and lowering emission of NOx by classified combustion are described. Combined with actual operation, low-NOx combustion rehabilitation programs and relevant test to be done is to be proposed. The actual operation of the unit achieved good results after the transformation, provide a reference for similar units. © (2014) Trans Tech Publications, Switzerland.

The general information and features of supercritical unit are illustrated. According to the engineering application situation, by comparing two feedforward methods, the new method application effect than classic control method, the response of unit's load is much faster than before. It's benefit to Automatic Generation Control (AGC). It's hoped that the analysis and optimization can provide useful experience and lessons for the design of the supercritical boiler control to some extent. © (2012) Trans Tech Publications, Switzerland.
