However, the relative difference in ΔT within a data set can be used for quantitative comparisons.
The effect of the weave pattern can clearly be seen in both data sets.
To account for the different spatial resolution of the two data sets, the length has been normalised.
The data in Fig. 6(a) is comprised of 9 images stitched together while Fig. 6(b) is a single image.
(a) (b) (c) Fig. 8 : Normalised ΔT data from natural frequency loading with increasing damage increments The effect of the damage on the stress concentration at the bolt hole can clearly be seen in the data in Fig. 8(b) and (c).

Besides, by using dimension reduction on high-dimensional data set, it realizes to extract the key factors of supply chain performance and breaks the bottleneck that problems in supply chain management cannot be recognized rapidly or analyzed by traditional performance evaluation method.
Regard as a high dimension data point to calculate the distance concentration of nth data point, which will be used for the weight of each PAC learning machine.
The total number of sub-data sets is, and .
Step 2 Analyze the corresponding ith sub-data set of the jth PCA algorithm, n first principle components, which are sued as n out vectors, i.e., the first principle component from different data sets.
The number of samples for suppliers in 2007 is 70, so the failure rate of data is 15.98%.

Emission data plays an important part for assessing control measures and development of technology.
Initial Values Databases contain all the data which can be used while Fuel Burn Emissions has the whole results of calculation.
The deviation of individual data reaches about 9%, because actual datasets are abstracted from average values not the data of detailed divided segments, while the computed emissions are very accurate by detailed segments division.
But the relation is not very clear for lacking of adequate data of more other flights the software needs.
The relation between emissions, fuel burn and type of engines is not very clear because of lacking adequate data, but there is no doubt that the relation will be set up and stronger and more clear after in effort to get adequate data of more flights.

The rolling process can provide excellent combinations of cost and process reduction than existing one.
Internal property data for AISI 304 stainless steel in DEFORM-3D is used as property of billet. 3.
(4) Initial material which diameter is 100mm and thickness 25mm is possible to transform with thickness up to approximately 7.5 mm with 81% or higher of area reduction rate.

Frost Resistance: Field Data, Correlation with Characteristics, Modeling The results of the samples mass loss study before and after 350 cycles of frost influence showed an increase of «M» on average by 0.29% of the mass of samples saturated with salt solution before the beginning of the research.
In addition, data on water absorption kinetics and capillary suction (WM and Wca [20]) obtained in previous studies, according to DSTU B V.2.7-170:2008 and EN 1015-18:2002, are coordinated with water absorption data WM.F received during the frost resistance test.
In view of the fact that there is sufficient interdependence between the experimental KF data and compressive strength of the main sample cubes frost resistance tested (fcm.F), further analysis of the correlation existence was carried out between fcm.F and «significant» characteristics of concrete (refer with: Fig. 1).
To assess the degree of impact of prescription factors on the preservation of fcm.F, according to the experimental data obtained, a quadratic experimental-statistical model (ES-model) has been built [23], which is adequate to the experiment with an error of sе{fcm.F} = 1.96 MPa with 17 statistically significant coefficients at bilateral risk 0.2 (refer with: Eq. 1).
The results of the study on fcm.F is generally consistent with capillary porosity data Wca [20].

The EBSP orientation data were collected at the quarter position on the longitudinal plane.
The starting material was obtained after cold rolling to 60% thickness reduction and then annealing at 700°C for 30 minutes to develop a fully recrystallized grain structure.
From the EBSP data, the fraction of twin boundaries (misorientation of 60°) was about 45 percent.
Fig. 3 grain-boundary misorientation distribution constructed from EBSP data of the starting material after cold-rolling and annealing.
Figure 4 shows boundary misorientation maps obtained from EBSP data on the 36%Ni steel ARB-processed from one cycle (ε=0.8) to six cycles (ε=4.8).

Domestic scholars mostly using time series data, they did researches on whether there exist EKC inverted "U"-shaped curve between economic growth and environmental pollution, but came to different conclusions.
Therefore this paper take relationship between industrial economic growth and environmental pollution as the research contents, based on the environmental Kuznets curve hypothesis, using the environmental and economic data of Chongqing ranged from 1995 to 2009, analyze the relationship between the Chongqing industrial economic growth and environmental pollution.
According to the data of Chongqing Statistical Yearbook and Chongqing Environmental Gazette, we can find that in Chongqing industrial wastewater emissions generally showed a declining trend, decreased from 0.956 billion tons in 1995 to 0.657 billion tons in 2009, an average annual decline of 2.64%.
Analysis of Results Based on the data of Chongqing Industrial GDP per capita and environmental pollution, take the industrial GDP per capita as the independent variable, and the industrial wastewater emissions, industrial gaseous waste emissions, industrial solid waste generation as the dependent variable, to do the cubic curve regression simulation.
In this regard, we propose the following policy recommendations: First, adjust and optimize the Chongqing industrial structure, exploit the "three wastes" emissions reduction potential.

According to the Traffic Masterplan data, Via Cristoforo Colombo can be characterized as follows: the total average number of (veh/h) for the two directions, is 5.921 during the daytime and 554 during night time.
About the other main roads and their limits by law, please refer to the data shown in Fig. 1.
The traffic data, calculated from the Traffic Masterplan, was seasonably integrated to include specific field measurement to calibrate the model.
During the night time, the burying effect, as expected, is a reduction of sound levels between 5 and 25 (dBA).
The selection of the most representative indicators was based on criteria of response to the question of information, scientific validity and availability of data [3,4].

Implementation of biodiesel in India will lead to many advantages like green cover to wasteland, support to agriculture and rural economy and reduction independence on imported crude oil and reduction in air pollution.
The data measured in the form of signals by various sensors are transmitted to the electronic control unit.
The fuel supply system is kept in neem oil mode and the data of manometer reading and exhaust gas constituents was recorded.
The data are recorded in neem mode.

Construction industry is an important tache and constitute in low-carbon city and emission reduction.
Fig. 1 Proportion of carbon emissions forecasting in China and the world in 2020 Low-carbon city refers to the urban space as a carrier,includes low carbon production and consumption [1], and it’s energy goal is to achieve 3d: demand reduction, decarburization and decentralization.
According to the Ministry of Construction, floor space of buildings completed currently is 20 million square meters each year, it is expected that in 2020, this data will add 13 billion.
