IMPROVING DESIGN OF DYNAMIC BALANCE CHARACTERISTIC FOR SCROLL COMPRESSOR’S TRANSMISSION SYSTEM by QIU HaiFei

“…In order to promote development of scroll compressor’s high speed and low vibration,and reduce its vibration and running noise,equivalent mechanical model and dynamic balance equation of the principal axis’ s transmission system were set up.Program of parametric finite element model for the principal axis assembly was developed on APDL language,and then its dynamic balance characteristic was improved based on that,and the location（ radius of the centroid R₂ and R₃） more reasonable of balance weight’s centroid was confirmed. …”

 ‘Twisting herself into all shapes’: blackface minstrelsy and comic performance in Harriet Wilson’s Our Nig by Elizabeth Boyle

“…This article argues that the practical jokes running throughout Wilson’s novel Our Nig; or Sketches from the Life of a Free Black (1859) are evidence of a deliberate and sophisticated comic strategy that exploits the spectacular body’s potential for subversive performance and works against the alienating conditions of social and political marginalisation experienced by African Americans in the antebellum period. …”

Single image visibility restoration using optical compensation and pixel-by-pixel transmission estimation by Yan YANG, Gao-ke CHEN

“…Aiming at image degradation in hazy and sandstorm weather,an optical compensation color restoration and pixel-by-pixel transmissvity estimation algorithm was proposed.The blue light was absorbed by sandstorm particles.The color shift phenomenon could be eliminated by optical compensate method,which convert the sandstorm images into hazy images.Then the ratio relationship between the minimum channel and its Gaussian function as the transmissivity,and median filter was used to eliminate its texture effects.The depth of the restored transmissivity alternated obviously and the edge was well preserved,which did not need the time-consuming postprocessing operativity.Finally,the image was restored by the atmospheric scattering model.The experimental results show that recovered sandstorm image treatment is better,and the saturation of the haze image is appropriate,the bright area is more nature,and running time is faster.…”

Research on power efficient autonomous UAV navigation algorithm: an edge intelligence driven approach by Chunmin LIN, Liekang ZENG, Xu CHEN

“…Autonomous drone navigation has received growing attention in the recent community.Compared with traditional navigation approaches which rely on location-based services highly, deep learning based visual methods have showed superior performance in self-adaption and generalization, which are a promising solution for autonomous navigation.Running the resource-hungry deep learning execution in the resource-constrained unmanned aerial vehicle (UAV), however, significant challenges were presented in power efficiency.To tackle this challenge, following the idea of edge intelligence, a deep reinforcement learning approach was introduced to dynamically configure the computational scale of the deep learning model on UAV and hence realize the autonomous navigation with low latency and high energy efficiency.Evaluations based on both simulation and real prototype experiments show that the proposed approach has the less energy consumption, longer navigation trail and higher obstacle avoidance rate.…”

Dynamics Modeling and Analysis of the Power Coupled System in Megawatt Wind Power Speed-increasing Gearbox by Wang Chunguang

“…Taking the wind power speed-increasing gearbox of load distribution type with two-stage planetary one-stage parallel axis as study object,considering the meshing stiffness,supporting stiffness and torsional coupling stiffness of the planetary gear mechanism and parallel shaft gear at low speed stage,medium speed stage and high speed stage,the dynamics model with considering the radial direction deviation and torsion deviation is established.The inherent characteristic of the model is analyzed,the vibration mode is divided into displacement vibration modal and torsional vibration modal and the vibration characteristics of each modal are obtained.Through changing the numerical size at all stages torsion coupling stiffness,the influence law of torsional coupling stiffness numerical variation on the coupling vibration state between low speed stage and medium speed stage,and medium speed stage and high speed stage is obtained.Through changing the connection types of all stages,the gear at all stages running at the coupling vibration condition can be decreased or avoided.…”

CALCULATION AND ANALYSIS OF INHERENT FREQUENCY FOR HIGH-SPEED DRY GAS SEAL TEST BENCH ROTOR by DING XueXing, WU YuanYuan, ZHANG WeiZheng, ZHAI Xiao, LU JunJie

“…In order to avoid the design of the rotor of the dry gas seal high speed test stand occur resonance phenomenon during high speed running,the transfer matrix method was applicated to calculate the natural frequency.Then it obtains that its natural frequency is 14044.586r/min when the dry gas seal static and ring `s quality is 33.78 kg in rotor system,and using the finite element method analysis the modes of the rotor system when it is operating in the vicinity of its natural frequency,then it will get the modal figure with four modal value.Comparative and analysis the results of the two methods,though simplified model are not the same,the results are similar.And the design of speed can meet the requirements,so it can describe the design of the rotor system is reasonable.…”

Research and implementation on acquisition scheme of telecom big data based on Hadoop by Baoyou WANG, Jing QIAN, Shijin YUAN

“…ETL is a very important step in the implementation process of data warehouse.A good ETL flow is important,which can effectively process the telecom big data and improve the acquisition efficiency of the operation platform.Firstly,the main data content of the big data platform was expounded.Secondly,in order to improve the efficiency of massive data collection,Hadoop and Oracle mashup solution was suggested.Subsequently,a dynamic triggered ETL scheduling flow and algorithm was proposed.Compared with timer start ETL scheduling method,it could effectively shorten waiting time and avoid the phenomenon of resources to seize and congestion.Finally,according to the running log of Hadoop platform and Oracle database,the relationship between acquisition efficiency and data quantity was analyzed comparatively.Furthermore,practice result shows that the hybrid data structure of the big data platform complement each other and can effectively enhance the timeliness of data collection and access better application effect.…”
