Figure 1 is the start experimental data of the car MAGOTAN 1.4L (this a dual clutch vehicle), the relationship among the opening degree of the accelerator pedal, the engine speed and time well illustrates that the first clutch begins to engage before the accelerator pedal reaches the target opening. 2.
The hidden layer nodes are 14 by calculation in this paper, BP network structure of predicting accelerator pedal opening is shown in Figure 2. 2.3 Data preprocessing The data sample which is obtained usually can not be directly used for network training, so before the training of neural network we should normalize the data sample.
There are many methods of normalization, this system makes the input data between the range (0, 1), and the specific function is expressed as: (2) —the normalized input or output value; —input or output sample values; , —the maximum and minimum values of the sample data changes.
After finish the data preprocessing, We divide the sample data into two groups, 70%~80% of the sample data is used as training samples and 20%~30% of the sample data is used as tested samples. 2.4 Parameters selection, network training and sample test A sample consists of the front 14 groups of data was selected to be trained according to the analysis of the data and the data that has major influence.
The constringency of the tolerance during the training progress is shown in Figure 3, and the data before and after training is shown in Table 1.

This forms the internally hosted private cloud data center.
Cloud data centers address this, through its isolated data protection feature.
They also share similar features of the data inside in the form of virtualized state.
Here we deviate a little from the purpose of a data center due to our own requirements for the study.
Establishing the cloud based data center in institution A in the table below seemed a tough ask.

Method This research was conducted using a quantitative method, namely a research method that involves direct data measurement to obtain quantitative data in the form of numbers.
In this study, Minitab Software was used both for determining the design of the Taguchi experiment (DoE) and for data analysis.
The right data types for ANOVA are nominal and ordinal in the independent variables.
After experimenting with 30 repetitions, the typing speed data words per minute is obtained as follows: Table 3.
The Taguchi experimental results Source: Data Processing Next is the identification of quality characteristics.

The calculated ∆H data are reported in Table 1 for M=Cu, Ni, Fe, Ti, Zr, Pd, Co, Al, Cr and Nb.
From the data of Table 1 one can see that for a few cases, Ni, Ti, Cr, Fe, the introduction of a substitutional metal in the Mg sublattice gives a positive solution enthalpy, ∆H>0, i.e., a global reduction of the thermodynamic stability of the hydride.
Our theoretical results also agree qualitatively with the experimental data from Ref
Our calculated data disagree for Al and Cu, while Nb seems to be a limiting case.
We note that there are no experimental data yet available to be compared to our predictions for Pd, Zr, Cr.

From 2002 to2009, the cement energy consumption per ton has also reduce over 40 percent in China, but there is great potency in energy saving and emission reduction.
The target of low-carbon building industry in the Eleventh Five-year plan and Twelfth Five-year plan is that until 2012 carbon emission reduction will drop about 56% comparing with the data of 2005.

It is necessary to pay attention to the model of reduction in terms of the production processes in the concept of pro-quality management under analysis.
With relation to this, an effective organization should be deemed to be one which via the most optimal activities creates the bases for the reduction of the costs of the functioning and the maximization of profit. [10] Interesting results of the research were attained in the sphere of assessing the impact of the system of quality management in accordance with the ISO 9001 norm for the economic effectiveness of small and medium-sized organizations.
The data analysis reflects that in the majority of organizations (66%) applying the requirements of the ISO 9001 norm, the indicator of profitability of sales is greater than 3, while a significant proportion of organizations registered this indicator at a level higher than 6.

The fracture toughness and the analysis of the obtained data were performed according to ASTM D 5045-96.
After 2 h of sonication, the tensile strength value was improved for the case of epoxy, however a reduction was observed in the case of hardener and epoxy/solvent system.
This reduction was lowest for the case of epoxy dispersion after 0.5 and 1 h of dispersion.

This is because CNTs and GNPs formed a more efficient percolation hybrid network, with a significant reduction in the role of contact resistance.
This is because that after the addition of aluminum nitrate in CNTs-PDA, -N= formed a coordination bond with Al3+, resulting in -N= reduction, and the emergence of a new bond -N-Al bond, indicating that Al3+ successfully bound to the surface of CNTs-PDA chemically.
After decoration of alumina nanoparticles to the CNTs–PDA , nine new peaks at 25.57, 35.14, 37.77, 43.35, 52.54, 57.49, 66.51, 68.20, and 76.86 are observed, which matched well with the (012), (104), (110), (113), (024), (116), (214), (300)and (1010) planes of the standard XRD data for the hexagonal α-Al2O3 phase (JCPDS No. 46-1212).

It obtains basic energy from oxidation of elemental sulfur and sulfide reduction state to provide energy for its own cell growth and metabolize.
Screening and voluming reduction before experiment, the safety size is >0.25 mm, less than 0.25 mm is not safety, it needs to be disposed [10-14].

By comparing the XRD results of C-PCM and pure paraffin, it is observed that a minor reference peak, which is present in pure paraffin is missing in the XRD data of composite PCM.
The reduction in latent heat of melting and solidification are 4% and 2%, respectively, which are within acceptable limits.
The latent heat of fusion and solidification are about 110 J/g and 107 J/g, respectively which accounts for 8 % and 2 % reduction as compared to before thermal cycles.
