Introduction Aluminium weight reduction potential when used as transportation material will surely meet the stringent environment regulations and improves fuel economy.
By minimizing the usage of steel and replacing with light weight material like aluminium can lead to an overall reduction in the weight of the car.
Conclusions · This paper has described the use of Design of Experiments (DOE) for conducting FSSW experiments with the 99% confidence level and empirical relationships developed from the experimental data can be employed to study the relationship between tool rotating speed, plunge depth and dwell time of friction stir spot welded Aluminium –interstitial free steel using response surface methodology

The main reactions were organics oxidation, ammonia oxidation and nitrate reduction.
Kinetic and stoichiometric parameters provide degrees of freedom for matching ASM model predictions with experimentally collected data.

It can be seen that be of HCPE is higher relative to diesel engine by empirical data, but compared with traditional engine driving pump system, there is a reduction by 20.67%～87.67% under total working conditions.
When α turns bigger and n turns lower, combustion condition rapidly deteriorates, which results in the evident reduction of pc.

The data were obtained at room temperature and typically the operating pressure in the analysis chamber was below 1×10 -8 Pa.
In contrast with the crystalline V2O5, the disappearance of some peaks shows the reduction of crystalline arrangement in c-direction with organic molecules intercalating in the interlayer[6].
Some reduction always occurs during aging of V2O5-based composite.

Some of the proven benefits of the six sigma system are productivity improvement, customer satisfaction, defect reduction, cycle time reduction, and culture change, etc [11, 13].
The response surface methodology (RSM) has been implemented to optimize the collected experimental data.

And the power plunged from 2839W to 2594W, the reduction is 254W, it is about the amount of power provided by one section.
And the power plunged from 2522W to 2291W, the reduction is 231W, it is about the amount of power provided by one section.
Conclusion Based on the relevant historical data accumulated for a long time, the thesis elaborated the abnormal phenomenon of the power of certain GEO satellite solar array, and analyzes the cause of the abnormal phenomenon.

The review of the literature suggests that coolant supply cutting Inconel 718 provides several advantages in terms of tool wear reduction and surface finish.
The experimental system consists of a vertical machining center (DMU 80T CNC milling machine), a three component dynamometer, a charge amplifier, an 8-channel data recorder and a PC based software for online monitoring and recording of the cutting force.
This indicates that the amount of reduction of temperature by the cooling air and presence of MQL application enabled favorable lubrication between the cutting tool and the work-piece.

Therefore, exploratory development of compositon of the electrode materials, internal resistance, stomatal aperture, size and shape in the electrode microstructure has become an important method to improve the electrode performance, including highly active catalyst for oxygen reduction, stable and efficient gas diffusion electrode and collecting way.
The global module design of battery Through calculating, the current density is determined at 50mA/cm2, and has 44 monomers and two-sided oxygen electrode which is made up of two parts, each of whose size is equal to the original data size of monomer battery, and pile series connection module design.
According to the oxygen's cathodic reduction reaction, calculate the minimum air demand, and according to the result, the appropriate draught fan and air transmitting way is determined.Air will be transmitted to the bottom of the pile through two aerofoll fans which is parallel connected, and then go through each baterry cell's surface of oxygen electrode and finally discharged from side above.

Also, FMEA allows the prosperity of a company through its contribution to cost reduction in the phase of design and development of a particular product and through reduction of defects registered with the client in the subsequent exploitation. [2].
Some of the data can be seen in Table 1.

Introduction The monitoring of environmental parameters is a process of data collection and studies and monitors systematically and continuously the variables concerned, in order to identify and to evaluate qualitatively and quantitatively the conditions of natural resources at a certain moment, as well as their trend along the time [1,2].
It is worthy to point out that in the decreasing of relative humidity down to 50 %, the removal of water molecules resulting from physical adsorption promotes a reduction in the values of capacitance.
Comparison of the Reduction of Metal Oxide Surfaces: TiO2-anatase, TiO2-rutile and SnO2 rutile.
