Research and implementation of intelligent terminal lightweight face recognition system by Guo-jun MA, Hai-dong ZHOU

“…In order to solve this problem that traditional face recognition scheme was not efficiently suitable to intelligent terminal scene.An improved lightweight scheme of feature weighted clustering matching based on SIFT was presented.The scheme can learn automatically and adaptively add test samples to the training sample space.Reasonable division and scientific distribution of weight make this scheme has improved at run time and recognition rate.The improved algorithm has been tested in the ORL face database and Yale face database,compared with the classical SIFT algorithm the recognition rate improved by 6.13% and 14.11%,the running efficiency increased 9.1% and 4.7%.At the same time,in accordance with the test method by Zhou,in the ORL face database,the recognition rate was up to 74.05%,significantly improved than PCA,LBP and other classical algorithm.The algorithm in Android terminal is implemented,and the improved algorithm is verified to be available in the Android system by experiments.Finally,an improved scheme was proposed based on the cloud architecture.…”

Forecasting the Remaining Duration of an Ongoing Solar Flare by Jeffrey W. Reep, Will T. Barnes

“…We test this on a large collection of flares observed with GOES‐15, and show that it generally outperforms simple linear regression, giving a median error of less than 2 min for the approximate end time of a flare. This random forest model is computationally light enough to be performed in real time, allowing for the prediction to be made during the course of a flare.…”

A TSN traffic scheduling algorithm combined with enqueue shaping by Wenxuan HAN, Hailong ZHU, Xinxin HE, Yanjue LI, Changchuan YIN

“…Most of the existing studies on the scheduling of mixed traffic in time-sensitive network (TSN) focus on how to ensure low-latency of stream reservation (SR) traffic.However, SR traffic blocks best-effort (BE) traffic for a long time will lead to excessive delay in BE traffic, which is not conducive to the state maintenance of network and the management of system.In order to reduce the maximum end-to-end delay of BE messages, a traffic scheduling algorithm which combines with enqueue shaping was proposed.It reduced the blocking of BE traffic by reducing the reserved bandwidth of SR traffic.The algorithm first added enqueue buffers in front of SR queues.Then, the reserved bandwidth ratio among the same priority traffic was adjusted by setting the number of frames in each enqueue buffer entering the SR queue during enqueue shaping.Finally, it jointed egress shaping to reserve bandwidth resources for each SR flow to match its latency requirement.Simulation results showed that combining enqueue shaping can reduce the maximum end-to-end delay of BE messages by 9.66%～75.76%.…”

Influence of Parameter on Dynamic Load and Load Sharing Characteristic of Split Torque-combine Power Gear Transmission System by He Lin, Sanmin Wang

“…By applying the fourth order Runge-Kutta algorithm to solve the system dimensionless dynamical equations， dynamic load characteristic is analyzed under the excitations of backlash， general transmission error and time-varying mesh stiffness. The results show that dynamic load factor happens to jump to 2.705 under the backlash excitation， load sharing characteristic keeps very similar on the same stage when general transmission error varies， the dynamic characteristic vibrates severely on split torque gears while the perturbation factor of time-varying mesh stiffness is larger than 0.25， the investigation will provide a guidance for dynamic load design of this typical gear system.…”

False traffic information detection based on weak classifiers integration in vehicular ad hoc networks by Xiang-wen LIU, Ya-li SHI, ENGXia F

“…Vehicles report traffic information mutually by self-organized manner in vehicular ad hoc networks (VANET),and the message need to be identified in the open network environment.However,it is very difficult for fast moving ve-hicles to detect a lot of traffic alert information in a short time.To solve this problem,a false traffic message detection method was presented based on weak classifiers integration.Firstly,the effective features of traffic alert information was extended and segmentation rules were designed to divide the information feature set into multiple feature subsets,then the corresponding weak classifiers were used to process feature subsets respectively according to the different character-istics of the subsets' features.Simulation experiments and performance analysis show that the selected weak classifiers integration method reduces the detection time,and because of the application of combined features,the detection rate is better than the test of using only some of the characteristics.…”

Cascaded algorithm for background modeling using pixel-based and block-based methods by Wen-hua XIE, Ben-shun YI, Jin-sheng XIAO, Liang-cai GAN

“…Block-based background modeling couldn't obtain the exact shape of foreground,while pixel-based approaches couldn't handle non-stationary backgrounds effectively.To solve the problem,a hierarchical scheme for background modeling was presented.The hierarchical model used block-based method proposed to obtain coarse background and foreground regions firstly,and then the operations of pixel-level foreground refining and model updating based on Gaussian mixture model were performed on special regions of the input image.These two algorithms in different levels were combined by adopting an asymmetric feed-forward strategy.Experimental results show that the hierarchical method proposed can obtain the exact shape of foreground and process non-stationary scenes well,in addition,it is insensitive to illumination change and can provide better results than any single approach in it,meanwhile,the integrated computation time is shorter than the sum of those of running the block and pixel-level methods,and satisfies real-time processing.…”
