1利用图像分析技术评价发酵面食品品质的研究显示文摘利用C-Cell研究两种有代表性的发酵面食——面包和馒头的瓤部纹理结构,探索以仪器分析代替感官评价的可能性.结果表明:利用C-Cell对面包芯纹理结构进行分析时所得到的某些参数之间具有显著的相关性,表征切片大小的参数与气孔数量和面积以及气孔平均延长性显著正相关;切片亮度与气孔对比度显著相关,而后者与表征瓤部纹理细腻程度的参数显著负相关;此外,气孔壁厚度、孔洞的存在以及气孔直径等参数均与面包芯的粗糙度显著相关.同样,利用C-Cell可以得到相对准确而客观的馒头内部纹理结构的优劣评价,其中,气孔对比度、气孔直径、孔壁厚度、粗糙气孔体积以及气孔延长度等均可用于馒头内部品质的评价,对小麦粉馒头加工品质的质量评价具有重要的意义.孙辉 Shuping Yan F.

2STUDY ON THE PREDICTIVE METHOD OF BUCKLING DEFORMATIONS OF THIN-PLATE WELDED STRUCTURES显示文摘The buckling formation and influence factors during welding thin - plated structures were investigated based on finite element methods, An engineering treatment method for prdicating the buckling distor- tion was proposed in here. It was used the equivalent applied thermal - load to simulate the welding residual stress,therefore the calculation of complex welding distoriton can be transformed into 3D elas- tic structural applied- load analyses, which can reduce the quantities of calculating works effectively. The validation of the method was verified by comparison of the numerical simulation and experimental results. The simulation of buckling distorition for side - walled structrues of paseenger train was per- formed and the calculation was in agreement with measuring results in general. It was shown that the main factors for producing the buckling were the intermittent fillet and ping the during welding the stiffened beams and columns to the panel.The existence of the free edge of panels would reduce the crit- ical buckling stress and enlarge the deflection obviously,but the continuous weld in closed frames didn’ t degrade the buckling situation.X.

8Generation of X-ray Emission in Repetitive Nanosecond-pulse Discharge at Atmospheric Pressure显示文摘Pulsed discharges can generate high power densities and high equivalent electric fields in plasma to emit X-rays,which is closely related to discharge mechanism.In this paper,discharge characteristics and X-ray emission of typical nanosecond-pulse discharges(corona,diffuse,spark or arc)are reviewed.Especially,the diffuse discharges are observed at pulse repetition frequencies up to 1 kHz.Factors influencing the discharge characteristics and X-ray emission are analyzed,such as the gap spacing,parameters of the applied pulse(amplitude,pulse repetition frequency),anode and cathode materials,and curvature radius of cathode.It is concluded that the maximum X-ray intensity is obtained in a diffuse discharge,and the X-ray intensity is affected by the pulse repetition frequency,applied voltage,anode material,and curvature radius of cathode.For example,X-ray intensity increases with the pulse repetition frequency and the atomic numbers of the anode material,but it decrease with the increase of curvature radius.It is also shown that the cathode material has no obvious influence on the X-ray intensity.ZHANG Cheng SHAO Tao YAN Ping Victor F.

9Quantifying the Microstructures of Pure Cu Subjected to Dynamic Plastic Deformation at Cryogenic Temperature显示文摘A pure Cu (99.995 wt%) has been subjected to dynamic plastic deformation at cryogenic temperature to a strain of 2.1. Three types of microstructures that are related to dislocation slip, twinning and shear banding have been quantitatively characterized by transmission electron microscopy (TEM) assisted by convergent beam electron di?raction (CBED) analysis. Microstructures originated from dislocation slip inside or outside the shear bands are characterized by low angle boundaries (<15°) that are spaced in the nanometer scale, whereas most deformation twins are deviated from the perfect Σ3 coincidence (60°/<111>) up to the maximum angle of 9°. The quantitative structural characteristics are compared with those in conventionally deformed Cu at low strain rates, and allowed a quantitative analysis of the flow stress-structural parameter relationship.F.

11PECS: Towards Personalized Edge Caching for Future Service-Centric Networks显示文摘Mobile operators face the challenge of how to best design a service-centric network that can effectively process the rapidly increasing number of bandwidth-intensive user requests while providing a higher quality of experience(QoE). Existing content distribution networks(CDN) and mobile content distribution networks(mCDN) have both latency and throughput limitations due to being multiple network hops away from end-users. Here, we first propose a new Personalized Edge Caching System(PECS) architecture that employs big data analytics and mobile edge caching to provide personalized service access at the edge of the mobile network. Based on the proposed system architecture, the edge caching strategy based on user behavior and trajectory is analyzed. Employing our proposed PECS strategies, we use data mining algorithms to analyze the personalized trajectory and service usage patterns. Our findings provide guidance on how key technologies of PECS can be employed for current and future networks. Finally, we highlight the challenges associated with realizing such a system in 5G and beyond.Ming Yan Wenwen Li Chien Aun Chan Sen Bian Chih-Lin I André F. Gygax 2019China Communications2019,16,8:3

13Generation of Runaway Electrons in Atmospheric Pressure Air Under 30-200 kV Voltage Pulses of Rise Time 1.5 ns显示文摘A pulse generator with a voltage rise time of~1.5 ns and voltage amplitude variable from 30 kV to 200 kV was designed for generating runaway electron beams in atmospheric pressure air with different interelectrode gaps.The influence of the voltage amplitude and gap length on the generation was studied.In the gas diode geometry under study,the gap voltage at which the generation of a runaway electron beam begins was determined.Decreasing the voltage pulse amplitude does not increase the beam current pulse width measured with a time resolution of~0.1 ns.It is shown that the escape of beam electrons to the downstream of the foil is sync in time with the voltage drop across the gap,and that the delay of beam current generation increases gradually from 1.1 ns to 2.6 ns as the voltage pulse amplitude across the gap decreases from~100 kV to 40 kV.Sergey B.

19Progress in Human Brain Banking in China显示文摘Human brain banks collect,preserve,and distribute postmortem and biopsied brain samples for histological,pathological,and molecular research.Different from the western countries,human brain banking in China has remained preliminary over decades.However,joint efforts during the past few years have substantially promoted this key frontier of neuroscience in China.This special topic brings together review and perspective articles on the ethical,administrative,and practical issues of brain banking.Several original studies report molecular and pathological characterizations based on banked human brain samples.Chao Ma Ai-Min Bao Xiao-Xin Yan Dick F.

20SIMULATON ON WELDING PROCESS OF T - JOINTS显示文摘T-joints are widely used in ship manufacturing and other welding structures.The welding residual stress and deformation hare significant influence on failure and service life in welding structures.By us- ing of 3D thermal elasto - plastic FEM, the temperature fields,stress fields and deformation of weld- ing processes on T - joints are analyzed in this paper.The moving heat source is considered in the com- putation. Moreover, weld metal filling and multiple - pass welding are simulated using activate/deac- tivate ability.For avoiding 'locking' in full integration elements of welding computation,the re- duced intergration elements are used in weld area.The nonlinear FEM analysis program MARC is used to complete the computations, as well as its user subroutines that are programmed to develop the special techniques needed in the simulation of welding process.Some different welding procedures are com- pared, and the welding residual stress and deformation are discussed in details.H.
