Nanofluids are created by dispersing nanoparticles of various materials (metal oxides, for example) in a base or carrier fluid.
In ferromagnetic materials, the complete magnetization typically remains aligned along the easy axis.

Realization CNC Controller Enable Machine Condition Monitoring Architecture Based on STEP-NC Data Model Firman Ridwan1,2,a and Xun Xu1,b 1Department of Mechanical Engineering, University of Auckland, New Zealand 2Department of Mechanical Engineering, Andalas University, Indonesia afrid003@aucklanduni.ac.nz, bx.xu@auckland.ac.nz Keywords: STEP-NC controller, Canonical Machine Command, Feed-rate Optimization Abstract.
This proved that the system is able to respond according to different workpiece material and spindle speed.
The key feature of the proposed NC program executor is the ability to perform adaptive feed-rate optimization by keeping a constant load within the machine tool’s capability.

Optimization and Application of Composite Index Method for Evaluation of Rock Burst Rating Zhang Jiayong1,2,a, Luo Xinrong1, Guo Liwen2 and Gong Xuemin2 1Faculty Safety Engineering China University of Mining and Technology, Xuzhou Jiangsu 221116 China 2College of Resources and Environment Hebei Polytechnic University, Tangshan Hebei 063009 China azjy815@163.com Keywords: Composite Index Method, Rock Burst, Weight, Analytic Hierarchy Process, Risk Index Abstract.
The most unstable coal bed is the material structural characteristics of the burst.
Therefore, to analyze the factors statistically, using the system engineering theory to find the influence degree of the factors in the process of the rock burst, then to obtain all factors’ weight based on the analytic hierarchy process, the product of the weight and the corresponding real index is the risk index and determined by every factor on the burst.
