Then principal component analysis was used for data reduction and finally quadratic analysis was used to grade the apples [4].
They can be viewed as a family of generalized linear classifiers which find the desired function based on given empirical data.
Thus it can maximize predictive accuracy while automatically avoiding over-fit to the training data.
The smaller the pairwise misranking error is, the better the prediction fits the training data.
Perhaps the data set is too small.

In spite of the large amount of experimental data published in the literature, the influence of metallurgical parameters (original interlamellar spacing, pearlite colony size, alloying elements) and of processing parameters is not yet well established.
Mechanical properties were examined by tensile test measurements to establish some relationships between microstructural data and the mechanical properties of cold drawn pearlitic steels.
Our pictures are consistent with published data obtained on similar steel and show elongated lamellae that are parallel to the wire axis with an interlamellar spacing much lower than 50 nm.
These data indicate that the dissolution rate of Fe3C seems to be higher in steel 2 than in steel 1 even if few stoichiometric Fe3C clusters were also found within lamellae.
More generally, in collected 3D-AP data, the C concentration in former Fe3C lamellae was found to be in a range of 4 to 13 at.% in steel 3 after drawing and few stoichiometric Fe3C clusters were also found within lamellae.

The intelligent vehicle suppresses the interference from both the software and hardware for sampled path information to guarantee the reliability of data.
The intelligent vehicle uses reasonable algorithm for data processing and real-time returns bodywork offset guide line distance.
The speed detection system is composed of integrated hall sensors and 8 magnetic steels symmetrically placed on reduction gear driven by motor.
Due to the sensors are adjacent each other, the infrared radiation launched from the launch terminal of a sensor may be received by adjacent sensors by diffusing and it is possible to data error.
Then read again and compared data of these three times, the consistent data will be the path information in this cycle.

The milling experiments were carried out on rotor material by uniform design method, which can make the experiment data highly dispersed and representative.
In order to make the experiment data more evenly dispersed in the range, uniform design table U13* with a deviation of 0.1442 is chosen to arrange the experiments.

In order to realize the carbon reduction, it has a certain theoretical and practical significance for the research of the relationship between land use change and soil carbon pools.
Data Collection and Analysis The data used to estimate land areas were extracted from remote sensing images.
The data of soil organic carbon from different types obtained from field laboratory experimental analysis soil samples.
Land use types were determined by a combination of supervised classification and manual interpretation of satellite images, supplemented with secondary information on geomorphology, historical vegetation maps, and ground truth data (Kilic et al., 2006).
This paper used both ERDAS Imagine 9.0 ,GPS and ARCGIS9.0 integrates the data using standard GIS features.

Data and Methods Data sources and processing.
In this study, landsat TM/ETM images covering the whole region, and whose imaging time were 2001.09.14(121-36, Landsat-7 ETM+), 2010.10.28(121-36, Landsat-5 TM) were selected as remote sensing data.
After radiometric correcting, geometric correcting and clipping, we carried out man-computer interactive interpretation and repeated modification until the data met the accuracy.
We evaluated the classification precision of images (taking 2010 as an example) using the land survey data in the same period and outdoor investigations of typical area.
As Table 2 shows, main reasons of farmland reduction were urbanization, increasing in industrial and mining land and surface subsidence leading to stagnant water.

This method was based on a fixed number of gyrations and was established on data from the virgin mixture and the 17% crumb rubber mixture at differing binder contents.
This is illustrated below in Fig. 1, for which a non-linear trend-line is shown to characterize the relationship most accurately for the available sets of data.
From an analysis of the data, a trend in variance was observed for the resilient modulus values between the load pulses in individual specimens.
The data from the test results suggest that with an increase in crumb rubber proportions, the variance in resilient modulus between loading pulses decreases as shown below in Fig. 2 and is quantified by standard deviation.
The remaining three data points in the mid-range correspond to the 20°C testing.
