Experiment data show that the fusion of multiple classifiers for face recognition has higher efficiency, accuracy of recognition and lower rate of error recognition.
Face identification technology not only avoids users being involved too much but also combines the advantages of contactless data acquisition and convenient hiding without any damage to the users, so it is called the most promising method of verifying the user identification in the 21st century[2].
Because face images are comparatively larger, the number of samples in face recognition is fewer, we extract principal components for data set by using PCA and reduce the dimension of samples.
The features after rank reduction are sent to SVM for study.

Based on the construction environment, theconstructiontechnology, the smaller earthwork excavation of deep high pressure rotary jet grouting pile with undrained caisson combined construction technology combined with monitoring data for the open caisson excavation control is adopted.
The hydrological condition As pore water,the project site of shallow groundwater, supplied by the atmospheric precipitation and surface water, it has certain hydraulic connection with the Yangtze river water level, during exploratory period underground water level buried depth is commonly 0.15 ~ 1.20 m, In case of rain or rainstorm, the underground water level may rise to the ground.According to the hydrological data, the project site along Yangtze River tide as follows: Table 1 The Yangtse River tide table Historical highest tide level 6.03[m] 0.1% design high water level 6.62[m] History lowest tide level -0.19[m] 1% design high water level 6.02[m] Years of average high water level 3.31[m] 97% design low water level -0.25[m] Years of average low water level 0.88[m] 99% design low water level -0.31[m] Deep well sinking construction Circulating water pump house connected caisson is divided into four sections, two sinking, about 23m sinking depth.
Table 2 Сaisson deviation form Quality common fault causes analysis Preventive measures and treatment methods Caisson tilt 1) Soil at the foot of caisson cutting edge is soft and hard uneven. 2) No even digging make the well surface difference in elevation. 3) Digging too much, caisson sink suddenly, easy to produce tilt. 4) The well abandoned soil or pile, Inoue and load points and uneven, resulting in the sidewall bias. 1) Strengthen the observation and data analysis during sinking ,discover tilt and correct timely. 2) In high blade feet side reinforcing soil, low side ,little dig or no digging, stay positive and then uniformly layered soil. 3) In lower blade feet side appropriate backfill sand, delaying the sinkingSpeed.
Caisson sinking too fast 1)In soft soil layer,soil compressive strength is small, make sinking, faster than the excavation speed. 2)Caisson external soil liquefaction. 1) Adjustment of excavation, no dig or partly excavation at the edge of the foot. 2) Filling the rough material between the open caisson wall and soil wall, or rammeding the earth of well Cylinder, increasing friction drag; as the external well, Soil liquefaction virtual pit, can fill gravel processing. 3) Reduction of each section of cylinder body height, weight loss of open caisson.

DLS data showed QDs and core/shell to be stable.
A more common method is to passivize QDs with layer of another wider band-gap semiconducting species, forming a core–shell structure and this passivizing shell provides several advantages including: (i) enhancement of QD luminescence, (ii) reduction of cytotoxicity by preventing the leaching of core and hence make them suitable for biological applications [4].
The TEM data shows the particle size lies in the range of 4-8 nm.

However, this method was modified by using undisturbed sample to compare the result with bar linear shrinkage method and the measurement was obtained by the reduction of its diameter at four points of the sample.
Materials and Methods Some past research had been reviewed to provide rationale data of the study and to give some information on the physical properties of the peat soil.
The data obtained was analyzed and compared with previous study to make a conclusion.
Table 2 shows the summary of data for all tests that had been conducted.
Modified shrinkage data was obtained from the average of four points measurement.

Necessity for reduction of greenhouse gases emissions, the growing demand for improvement of biorefinery technologies and the development of new biorefining concepts, oblige us as a society, mainly scientists, to develop novel biorefinery approaches.
The legislative ideas and policy actions included in the Fit for 55 package are as follows: 1) the EU's emissions trading system, 2) member states' emission reduction targets, 3) emissions and removals from land use, land use change, and forestry, 4) renewable energy, 5) energy efficiency, 6) alternative fuels infrastructure, 7) CO2 emission standards for cars and vans, 8) energy taxation, and 9) the carbon border, 10) sustainable aviation fuels, 11) greener fuels in shipping, and 12) social climate fund [2].
All the above-mentioned growing demand for the reduction of greenhouse gases and the improvement of biorefining technologies and the development of new methods oblige us as a society, mainly scientists, to develop sustainable lignocellulose (LC) processing technologies.
Three parallel tests were run for each sample, and the average of the data is displayed with a relative standard deviation (RSD) for all experiments that was less than 5%.

Without the half select condition, the proposed 10T cell allows efficient bit-interleaving to provide soft error rate protection and the dynamic power is also decreased significantly due to the reduction in the number of bitlines discharged and charged during the read and write operation.
When column-based write signal is activated, the data will be written into the selected cell.
Because we do not need to consider pull-up ratio and the read margin during the write operation, the two pass gates (M7 and M8) and the portion for storing data can adopt the minimum size design.
