With the rapid increase of image data, how to retrieve has become more and more important.
Lots of image data are stored and transmitted in compressed format, but the study of image retrieval technologies are mostly not based on the data of image compression at present.
When we retrieve the compressed image data, we need the “full decompression operation”.
They. transformed DCT domain coefficients for the Mandala domain data.
Because when the ratio increases to a certain degree, the coefficient in retrieval behind process will lose the function, which is equivalent to the reduction of DCT coefficients in the number when retrieving, to some extent, will weaken the descriptions of the image information.

The working principle is as follows: first the SCM system sends commands to the driver of stepper motor, second the driver chip drive stepper motor, third the robot move to the joint through reduction gear, then the peristaltic pump starts to dispense, At last the robot returns to the initial position.
The upper microcontroller is responsible for the management of entire system, the calculation of kinematics, the planning of trajectory, detecting the signal of sensor, sending data to the lower microcontroller.
The lower microcomputer is mainly responsible for receiving the data, and then controlling stepping motor to drive manipulator to move at the accurate positioning and controlling peristaltic pump to finish gluing task.
Fig. 6 Hardware Structure Diagram The upper and lower machine both adopts AT89C52 in the control system the manipulator, the upper machine is shouldering the task of processing data, and ATM89C52 only contains 256bytes random access data storage, so it is necessary to extend a piece of static data memory RAM6264 to meet the requirements; the upper machine not only can successfully completes the communication with the lower machine, but also realizes the communication with the PC through the switch; when the lower machine receives the value of each joint angle changes, it will control STK672-04 to drive the stepper motor, can achieve the manipulator motion; when the lower machine receives the signal to send dispensing or stop signal, it will control the peristaltic pump to finish dispensing.

The feature of BEB is that the size of CW depends on the number of collisions met by sending data packets.
SUM(send[i]) is the sum of data packets sending by the nodes during the NO.i monitoring cycle. 3.
When a node fails to send data, BEB algorithm would double the CW for the next channel competition.
This parameter reflects the ability of the network data processing.
The greater the throughput is, the stronger the network data processing capability is.

Each data package possesses a header which guides the receiver to take appropriate measure.
Data transferring is affected by switches or routers which locate among web cache, web server or clients.
When cache server possesses what clients request, the clients can directly acquire data without contacting the web sever.
The directive can be expired data, cache control or content-length.
This reflects that if the data element in heap can keep close relation with the users' visiting action.

It is the basic guarantee for reduction in fire casualties to improve the rescue ability effectively.
This system can record and analyze the process data, according to the accumulation of the historical information, directors can make effective decision and evaluation.
These connection will complete the data collection, calculation and connection function.
They will send information to gateway through wireless sensor network, which deals with these data and sends them to distal base through the local transmission network.
Then the base sent the data to the database server, finally the data is transmitted to firefighters through a terminal interface.

The paper divided e-commerce users into new users, general users, Silver users and Gold users, and recommended using different recommendation strategies according to the difference of users Data preprocessing Data preprocessing steps include: data cleaning, user identification, operation identification, perfect path, user transaction mode recognition.
After data preprocessing of the commodity recommendation system, the user transaction mode can be obtained, and generates files for each user transaction mode.
In the e-commerce system, the relevant data of new users is collected less, so we need to adopt a targeted approach of recommendation.
In this method, customer vector dimension reduction using factor analysis to get a few representative customer factors, then regression analysis is used by those customer factors on target customers to predict the assessment score of goods, and then recommend commodity which users are interested in.
Experimental data taken from access to records in a month, after pretreatment, get about 900 user transaction modes.

On the real multilayer weld will be described how to arrange whole experiment in order to obtain not only relevant input data but also verification data.
This approximately corresponds to a reduction in CO2 emissions by 30% [2].
The information obtained from the simulations can be used to support or develop a methodology how to obtain not only input data, but also data which verify the validity and suitability of the computational procedures that are used.
Mechanical analysis uses the results of the temperature-metallurgical analysis as input data and the most common results here are mainly stress and strain fields [4].
The determined geometrical data, which are necessary to define Goldak´s heat source model, are shown in the Table 3.

The lattice parameters (a and c) obtained from XRD data decreases with increase in cobalt content x.
The XRD pattern for pure Sr0.5Ba0.5Fe12O19 is in good agreement with JCPDS data (Cardno.51-1879).
Using the JCPDS data the peaks of the XRD pattern were indices for the hexagonal structure.
(a)Hysteresis loops(b)curves From Fig. 3(b), it is seen that the coercivity value decreases from 5478.8 to 2397.1 oe with increasing cobalt concentration (x=0.0 to 1.0) due to reduction in magneto crystalline anisotropy [11].

There are many measures of the energy consumption reduction.
The work in the paper used the experimental method to verify the effectiveness of the resistance reduction and energy saving[2].
Through the related datum, according to the hull lines of parent ship, this paper designed the model of SSD[4].
When the speed was 14.5kn, the open angle of profile was 12°, and the distance between the SSD and the propeller disc was 40mm, the received power decreased the most, the value reduced from 7076 to 6810, the amplitude reduction was 3.8%.

The results of this study provide important data that can aid in the design and optimization of SIDI CNG engines.
Based on the obtained experimental data, the predictive functions of the spray tip penetration S for the injected CNG across the combustion chamber have been calculated.
The data shows that the spray tip penetration increases as t0.58883.
Figure 8 shows the spray tip penetration as the function of ambient pressure and the data shows that the spray tip penetration decreases as Pa0.67898.
Figure 9 shows the spray tip penetration as the function of the injection pressure and the data shows that the spray tip penetration increases with Pinj0.25524.
