This paper is to study before researchers for and significant visual saliency and attention, and review the related data for the application of this aspect.
This paper is to study before researchers for and significant visual attention, and review the related data for the application of this aspect.
Based on visual attention model,Zhang Libao used high resolution remote sensing image spatial dimension reduction to determine the visual focus,and then according to the location of the focus, in the original remote sensing image to calculate the corresponding interest area.
Study of visual attention model, not only helps to understand the working principle of the human visual information processing, but also help solve the problem of data filtering and improve the efficiency of computer information processing.

Prior to the two-terminal admittance (Y = G + jB) measurements on the sample, measurements were carried out using the empty cell over the entire frequency range considered (100 Hz to 10 MHz) so that they are automatically subtracted from subsequently measured data.
Rietvield refinement of XRD data as well as Mossbauer measurements are underway to identify the species involved in the substitution process, which should provide detailed and direct substantiation on the hopping mechanism and might result in a more rigorous interpretation of the observed trends.
Impedance data at various frequencies and tempera- tures can be displayed in several forms suitable for extracting maximum of information about the material under study.
This may be attributed to a reduction in the capacitive effects of the bulk on Li-doping that will wipe out the effect of the respective increase in the bulk resistance.

Due to stricter limits, current research and development of new diesel engines are oriented towards the increase of engine power per unit volume of the cylinder, towards the increase of engine efficiency and towards the reduction of energy consumption.
To measure parameters as air pressure in the cylinder, it is necessary to use a device that is capable to respond immediately to changes and record the data, since the change takes only a few milliseconds.
Based on the evaluation of obtained data, we have found that in the third set of measurements at the angle of rotation of 30°, there was a significant drop in pressure at the end of the compression stroke from 2.3 MPa to 2.08 MPa.
All these measured data at the end of the compression stroke and the pressure drop increase in the intake manifold confirm the theory of the necessity of periodic inspections of the condition of air filters.

Lossy wavelet coders provide much greater energy compaction than lossless methods, efficiently representing large amounts of data.
Computation of the lifting-based DWT can be explained via a data dependency diagram as shown by a block diagram in Fig.1, For the DWT requiring four lifting factors, such as the (a-b-c-d) filter, the computation is done in four stages as shown in Fig.1.
The multicomponent transform is effective in reducing the correlations that cause reduction in redundancy and increase in compression performance.

Considering that MC9S12XS128 reads more slowly than OV6620 output speed, the high-speed, low-power, asynchronous FIFO dual-ported SRAM IDT7008 is applied to do the data cache to optimize the system.
OV6620, PAL standard, 25 frames per second, 2 fields per frame, then 50 fields per second, i.e. an image is to be produced every one second, 356 x 292 pixels, has high sensitivity, high integration, and great power-reduction relative to CCD.
On the data transmission with MCU, without A/D converter and video sync separator chip LM1881, the field synchronous interrupt signal is ready-made.
Program flowchart Black-Line Extraction Algorithm In order to show the obvious black-white effect of the image, the collected image grayscale data is done the binarization to obtain the binary image.

Since the above data are on 150 mm can not give complete information regarding downfall density using the new automatic reactor, some data was collect on 4H-SiC-4H 100 mm epiwafers produced with the same automatic reactor.
Defect density data collected on 100mm 4H-SiC-4H epiwafers processed with PE1O6 showed a clear reduction of downfall density (< 0.5 cm-2) also for high epilayer thickness.

For discretization finite element model system, any unit can establish energy equation which is similar to the form of up type (among them no crack or no crack propagation units, regardless of the crack propagation energy consumption), group all units of energy equation and reduction finite element incremental equation can be given: (4) is the total stiffness matrix calculation system of thestep, and total stiffness matrix with crack cracking process continually changes; is overall displacement incremental array of thestep; is overall the load incremental array of thestep; is the equivalent excessive nodal force array of tension failure unit of thestep: (5) is the summation of tension failure unit which is beyond the time step; is the transposed of unit geometry matrix; is the stress value of rupture surface of tension failure unit.
In addition, according to the monitoring data simulations shows that the displacement of slope 3157 which near airport changed with time, and then accelerated deformation gradually, until a more stable.
The data of slope simulation and Haizhou mining area monitoring has been very good anastomosis.

Introduction A cell counter is an essential apparatus providing quantitative data in cell culture and biological analysis [1,2].
The former detection method is based on the resistivity reduction occurred when the cells pass through small aperture (order of micrometer size) and the latter is based on the fluorescent markers, attached on the cells, emitting fluorescent light when they are stimulated by laser [3-5].
Spin-On-Glass (SOG) was coated on top side of glass substrate and cured following temperature profiles in data sheet with thickness of 0.8 µm.

The literature [8] introduced the theoretical analysis of the effect of installation of web cleaner on the airflow movement, and thought the web cleaner is conducive to the reduction of the pressure on back casing and improvement of card sliver quality.
The static pressure data on the casing, licker-in grid, back plate and cylinder screen at positions of inlets and outlets are used from Ref. [8], which are to be the initial boundary conditions for the numerical calculation.
Distribution of static pressure on the surface of taker-in and its casing Two experimental studies were also performed under steady state conditions and the tested data of each case were given.
Using the gauge pressure data of the forenamed tests in the FLUENT software computes distributions of static pressure on the casing denoted in the solid line and dashed line, respectively, in Figure 3.

Vickers hardness data obtained at room temperature were plotted in Fig. 5as a function of the volume fraction of the primary Ni3Al precipitates.
Hardness reduction from room temperature was mostly less than ~15 % even at the highest temperature (1173 K).
The discrepancy between experimental data and the mixture rule, i.e., extra hardeningΔHv was however recognized in each alloy and at each temperature.
As one possibility, the observed difference may be attributed to different behavior in thermal expansion 0 20 40 60 80 100 200 300 400 500 600 Volume fraction of primary L12 (%) Vickers hardness (Hv) Base alloy Nb addition Ti addition Fig.5Variation of Vickers hardness with the volume fraction of the primary Ni3Al precipitates for the base, Nb added, and Ti added alloys.Data obtained at room temperature are plotted. 6 8 10 12 14 0 100 200 R.T. 573K 773K 873K 1073K 1173K Al contents (at.%) ΔHv Fig.6 Variation of extra hardening ΔHv with Al content at various temperatures for the Nb added alloys.
