A reduction in cutting forces was observed with the increase in vibration amplitude.
An average 25% reduction in cutting forces was found by the increasing vibration amplitude from 10 µm to 30 µm (Figure 6).
For all the three cases a reduction in cutting forces with the increase in frequency was observed (Figure 7).
An average 36% reduction in cutting forces occurred when the frequency increased from 10 kHz to 20 kHz.
Authors would also like to acknowledge Tampere University of Technology, Finland for providing material data for Ti alloy.

By this process, we identify performance and applicability of chosen sensors and also obtain base data for analyzing measured value in unknown conditions.
The extent of pipe thickness reduction can be monitored by Non-Destructive Evaluation (NDE) techniques.
This test shows clearly the relations between force and vibration mode, and it would be base data to compare to the result obtained in the real situation.
For this purpose, specimens with different thickness are used in the test, and thus we could get preliminary data of the test condition similar to FAC occurrence.
Since we don't know what would be the characteristics of the vibration mode in the specific system, we tried to break down the phenomena case by case to obtain the baseline data here.

More generally, the outcome is some combination of energy consumption reduction and improvement of life quality.
Clinch et al. [22] have proven that the rebound effect will, by its nature, diminish over time as the housing stock achieves a higher level of comfort by energy efficiency improvement (see Fig.2), by using time-series data on residential energy consumption in Ireland.
However, the findings regarding the rebound effect in the household energy efficiency of China and its related influence on energy demand and energy security are only perceived without direct data proof.
Hence, in the future, we will collect the relevant data to prove the existence of the high rebound effect with more accurate value.

There is still insufficient data from the excavation of smelting furnaces dated to the Joseon Dynasty.
This process would have had the effect of pre-reduction, among others.
Not much data exists as to the production of cast ironware in the Chungju region.
As only analysis data on iron bars exists at this time, further research into intermediary materials is required.
Archaeological and scientific studies into these sites need to continue, and experimental archeology studies carried out based on accumulated research data will able to enhance the general level of research.

The low frequency sub-band images abstracted by DWT not only retain the main characteristics of the original image, but have the less data dimension compared with the original image[[] M.Zhu and A.M.Martinez:discriminant analysis.IEEE Trans.Pattern Analysis and Machine Intelligence,Vol.28(8),p1274-p1286,2006. ].
After passing a series of transitions, the image dimension number is reduced, largely reducing the disposing data amount of recognition dispose machine, and decreasing the noise and redundant message[[] Yuan Weilin,Ma yan,Liu Shengwei: " Analysis of Remote Sensing image compression based on DWT and Matlab".Geomatics World 2013(3) ]
Usually speaking, in order to satisfy the accuracy requirement, k shall be no less than 5, that is to say, every image will require at least 320 pieces of data to display.
Due to the large data size, the matching rate during the recognition process is slow, and the running time is too long.
However, the paper has not given detailed description in terms of the training classifier, and excessive data is filtered during the DWT process.

Foreign and domestic scholars have made a wide range of researches in damage identification with data of vibration.
Node vibration data far from the damage location was selected and collected to form the objective function.
How to find test points and collect data far from the location at the upper of the jacket.
Based on tested modal in q nodes, the modal data in the direction with the biggest range of variation can be selected as test data.
The data are used to form the objective function needed in the optimization module, the function is minfx=1nk=1n(Zij-zij)2

Based the panel data of China from 1997 to 2008, this paper constructed the regional total-factor energy efficiency (TFEE) by using the method of the data envelopment analysis (DEA) and then discussed the regional influence of FDI on local energy efficiency.
Some policy suggestions are also put forward for energy-saving and emission reduction target.
Mielnik (2002) came up with the hypothesis that FDI has a negative effect on energy intensity after making an OLS regression of data from 20 developing countries [2].
In order to guide the boot of FDI and to save energy, the paper uses panel data of 1997 - 2008 of China to explore how FDI influence on Chinese energy efficiency.
All the data were extracted from "sixty years of new China's compilation of Statistics" and "China energy statistical yearbook" (1997-2008).

Chiller power consumption, P1 (kW) These data are normally readily available and displayed on a BEMS system shown in Fig. 2.
The COP values obtained from the above equation result in better accuracy due to the fact that they were generated from experimental data.
Based on the BEMS system operational data, each of the fourteen chillers’ performance curves is generated on site, enabling a default operating priority to be established.
The data indicate that strategy 3, with CH6, CH8 and CH3 running at 70%, 90%, and 80% PLF respectively, results in the lowest additive power demand of 2046 kW.
The operational data indicates that the system’s chilled water flow was not balanced and needed further adjustment.

The use of the heterostructures (HS) with the corrugated interface as active element allows one to increase SC photoresponse due to the front surface reflection reduction (optical losses).
For p-n (hetero) junction or for thin metal layer barrier Schottky photoconverters (solar cells) data of the total (specular+diffuse) reflection of light, Rsum allow to calculate the internal quantum efficiency ( )IReIQ sum phi )(1)( � � � = , where Iph is the photocurrent density, e is the electron charge, I is the incident light intensity.
Optical characteristics of microtextured surfaces determine ability of such surfaces for reduction of optical losses in SC.
These conditions are seen can be optimized for maximal reduction of optical losses (total reflection).
The optimized microrelief of dendrite type allows one to obtain somewhat more gain in a reflectance reduction than microrelief of quasigrating type.
