A data acquisition card with USB2.0 interface is used to obtain the real-time unbalanced signal.
The data collection of this system is used the Taiwan ADVANTAGE 4711A type data acquisition card, it can collect the information after the data acquisition board, and it can also send out the control command to control the action of the motors and the hydraulic system.
The AC variable frequency motor drives the milling cutter rotating; the rotate speed is controlled by the output voltage of the data acquisition card.
The hydraulic system is controlled by the voltage signal given by the data acquisition and realizes clamping and loosening.
From Tab.1, the measured data of the automated balancing machine designed is agree with the test data of the manufacturers.

Data collection process involves two types of data exchange, data exchange between data sensors and data collector, and data exchange between data collector and data center system.
Data collector and data center system must set their own data representation and data transmission format according to the character of the system.
Data transmission uses data flow for sending and receiving.
When the collector and the data center are connected, it begins to send data stream which includes the data of each sensor, data identification code and data meaning.
It realizes the sub metering of the building energy consumption, and energy saving and emission reduction.

Mechanical and physical tests were used to measure the retained properties and to observe the causes of damage and strength reduction.
The experimental data showed that resin properties may strongly influence the durability of FRP reinforcement, environmental combined cycles did not take to significant damage of conditioned specimens; steel fibers are sensitive to alkaline attack when resin does not provide adequate protection to fibers.
Then management of thickness, sizing and sorting with a starch removal and moisture reduction are performed.

I think that such evaluation is a result of applying outdated comparative data relating to the costs and amounts of produced crude oil.
Current data relating to the costs of one barrel of crude oil are carefully protected.
Nevertheless, basing on data gathered some years ago by Cambridge Energy Research Associates (CERA)[5], and keeping in mind that the cost of production increases each year, the following question is worth posing: Is the energetic balance of technologies based on recovery and combustion of crude oil still positive?
The above-mentioned data clearly indicate that half of daily production took place at the cost that was lower than the sale price, on the understanding that in oil industry this does not necessarily mean direct losses, as the barriers to exit are very expensive (huge fixed costs, long-term contracts).
The indisputable merit of using hydrogen as energy carrier is the reduction of toxic emission to the natural environment.

In this study, because three CCD cameras were used to detect obstacles and determine the guide
line of the AGV system, it was necessary that a PC-based hardware platform would be able to handle
a great deal of image data easily and quickly.
The command control module was constructed to transmit data and orders clearly between the main control and other modules.
It communicated with the main module by an RS232 serial device and with the others by an interrupt device of 8bit data port.
Thus, each module was constructed from classes for data processing and transmission to the hardware module, and each was run independently by the multi-thread method.
Two servo motors were set up with a planetary gear type speed reducer of 1/50 reduction ratio to drive the wheel in the central lower part of the frame, as shown in Fig. 5.

The advent of different molecular techniques that broadly categorized as non-PCR or PCR-based led breeders to estimate genetic diversity on the basis of data generated by different molecular markers, which provided a means of rapid analysis of germplasm and estimates of genetic diversity, which were often found to corroborate phenotypic data.
Fuentes et al. [11] compared different methods of genetic diversity estimates ,which showed that estimates based on RAPD data rather than AFLP efficiently represented the genetic parentage and phenotypic diversity between rice varieties.
The rapid changes in population size, ecological degradation and globalization have led to a dramatic reduction in crop genetic diversity.
As a mixture of blast disease-susceptible and –resistant varieties were grown, disease incidence was reduced by 94 and 89% increase in yield was noted in susceptible varieties.Wei et al. [21] showed that genetic diversity and allelic reduction occurred over time in Chinese cultivars.
Advances in informatics and communication techniques have also markedly increased our capacity to use, analyse and communicate related data and information.

Material and methods
The interest for practical medicine is focused at the data covering the effects of plasma-based chemical surface modification of materials with different degradation rate as well as biostable ones.
The data on the contact angles of several test liquids in one sample allow measuring the free surface energy of the solid sample.

Reduction of the polar component may be explained by the changes in the number of polar groups, electric charges and free radicals.

Introduction
Nowadays, monitoring water quality parameters can be done using an online system with the advantages over the conventional method include: less time consuming because data can be obtained in real time, inexpensive without the need for human to collect water samples and transport them to laboratory, and more accurate since some oxidation reduction process must be measured on-site [1].
On the other hand, measurement data must be obtained and transferred across geographical location continuously for analysis purposes [2].
The main component of an online water quality monitoring system is the sensors, where measurement data were produced from physicochemical interaction with the water samples.
Data were taken for 5 min by applying an input voltage of 1.4 V with DO concentration of 6.7 mg/l (represents the largest deviation from the regression line in Figure 2(b)).
Central to the operating principle of the sensor was the RuO2 working electrode, where the reduction process of O2 took place.
