Computer data processing mode in the era of big data from pattern recognition to intelligent sensing is discussed in this paper. Intelligence refers to the interconnection between things and things and people through the Internet of Things and mobile Internet, combined with the general big data computing, communication, artificial intelligence and other technologies. Neighborhood dependence reflects the proportion of approximate samples to all samples under decision class in mixed information system, and it is also a measure to describe the degree of relationship between conditional attribute set and decision attribute, so it can be used as a heuristic function to reduce the attribute of mixed information system. This paper designed the model from the collection to processing, from pattern analysis to the intelligent sensing. The experimental results have proven that the proposed model can sense the data effectively.

Scenario test for advanced driver assistance systems function based on V2X technology is the most important step before any application to be put into practise. Lots of advantage V2X applications were intended on warning the threaten from blind spot of driver which are much more strict than the other function based on cameras or microwave radars always. Because of the high safety risk induced by drivers and vehicles, it has to avoid these scenarios with only software test or even vote of experience. To test the original design fully, this work offered a method which was integrated by cooperative navigation and wireless communication technology. By using the structure of cooperative system, the Kalman Filter was selected for the estimator for tracking the moving target and a novel virtual-real interaction concept was suggested for high speed, high accuracy and high risk test scenario. The designed system can play as a vehicle of a crowed of vehicles to accompany with the test vehicle, so not only the wireless network can be offered, but also the motion simulation. Each part in the system was detailed by mathematical model. Compare to other test methods, the suggested method has advantage in low risk, high accuracy and high efficiency. And the relative navigation keeps a desire distance between the scenario design and real time information.

Signal collision is a very common phenomenon in broadcast wireless communication such as V2X network by lacking of central regulator due to its high speed and complex traffic situation. However, it also contains useful information which can enhance environmental awareness capabilities to adjusting transmit power for keeping the channel's busy ratio under a desired limitation especially. This paper suggests an improved HMM model for information perception by measurement on collision time's length without any changes in V2X communication standard or wireless hardware. Essentially, it's designed to estimate the number of collision nodes by combing the characters of BSM as the apriori knowledge and the periodic surveillance records on control channel as the measurement information. The significant change compare to our previous work is in the initial conditions estimation with types of BSM which is more realistic. The clogged city scenario which induces signal collision easily was selected for test the performance of suggested method with a fully connected network. Computer simulation's results showed that the suggested model can work well with high accuracy also even with different types of BSM which contains kinds of additional information.

Considering the elasticity of aircraft in gust, the L1 adaptive control can respond quickly while keeping up robust performance against elastic deformation. This paper presents a designed method of gust alleviation controller based on L1 adaptive output feedback. The pitching angle rate and the normal acceleration at the center of gravity are used as the feedback signals. The flap and the elevator are selected as the control surfaces of the gust alleviation system. Applying L1 adaptive output feedback controller can reduce the residual overload in gust. In the design process, the nonlinear part and the elastic part in the elastic modal plane model are considered as uncertainty in L1 adaptive control. The adaptive law can estimate the uncertain parameters and the low pass filter can keep the robustness. The simulation results show that the L1 adaptive control can reduce the influence of gust in the longitudinal of the aircraft.

A control method of variable lane based on video detection is proposed in this paper to handle the adaptive switching of the lane's oriented attribute. Based on the image calibration, visual loop detectors are built up in the surveillance video of the intersection. Then, the characteristics of the traffic flow, such as flow rate, velocity, queue length, can be obtained by the video detection based on these detectors in real time. With further analysis of the traffic flow in the channelized lane, the variable lane's orientation is determined for the objective of enlarging the traffic capacity of the intersection. Based on the simulation on the software VISSIM, we verify that the proposed method can enhance the traveling capability and reduce the congestion, compared with the original control method.

Now Eucalyptus wood begins to be used to pulp. However, water, adhesives and other assistants are severely wasted because the extractive of Eucalyptus wood is enriched. What is worst, water pollution becomes more serious because of the polluting extractives of Eucalyptus wood. Therefore, based on the single-factor method, the fresh E. camaldulensis shavings were treated in the sorbitic extractor and supersonic wave extractor. The extractives were analyzed by ZETA and SIZER to find out the leaching rule of nano particles from E. camaldulensis wood, hence to obtain the way to lower the negative effect of the extractives. The results were following as: (1) the regression curve showed that the extraction mass increases when the extracting time extends in the sorbitic extractor; (2) diameters of leached nano particles distribute from 37.8 to 106 nm by volume evaluating indicator, and 28.2 to 91.3 nm by number evaluating indicator in the sorbitic extractor. The particles with diameters of 4150~5560 nm, 1110~6440 nm and 4150~5560 nm are too few to test, and their volume are only 0.3%, 2.6% and 0.3% respectively, however, they can bring barrier of wood extractives on wood permeability and obstructive action of wood turpentine on pulping; (3) the volume of the particles with diameter of 28.2~78.8 nm was 80.1%, the number of the particles with diameter of 24.4-50.7 nm was 89.0%, and the volume of 190-396 nm particles is 15.2%, but its number was very less. Therefore, not only extraction mass is increased but also the grouping number of leached nano particles from E. camaldulensis is lowered in supersonic wave extractor.
