一种网络社团划分的评价及改进方法

主要从节点在所属群体内的相对重要程度出发,尝试性地给出一种网络社团结构的新定义,并在此基础上构建了一种网络社团划分的评价及改进方法。该方法既可以与现有的社团划分算法进行组合,形成新的网络社团划分算法,也可以独立使用,对网络社团的划分结果进行评价与改进。最后,通过MCL、GN、Factions等方法及算例对提出的算法进行了验证与分析。

Gear Fault Detection Analysis Method Based on Fractional Wavelet Transform and Back Propagation Neural Network

A gear fault detection analysis method based on Fractional Wavelet Transform(FRWT)and Back Propagation Neural Network(BPNN)is proposed.Taking the changing order as the variable,the optimal order of gear vibration signals is determined by discrete fractional Fourier transform.Under the optimal order,the fractional wavelet transform is applied to eliminate noise from gear vibration signals.In this way,useful components of vibration signals can be successfully separated from background noise.Then,a set of feature vectors obtained by calculating the characteristic parameters for the de-noised signals are used to characterize the gear vibration features.Finally,the feature vectors are divided into two groups,including training samples and testing samples,which are input into the BPNN for learning and classification.Experimental results showed that this gear fault detection analysis method could well maintain the useful signal components related to gear faults and effectively extract the weak fault feature.The accuracy rate reached 96.67%in the identification of the type of gear fault.

The Electrophysiologic Effects of Sotalol on the Action Potential of the Nascent. Canine Purkinje's Fibers

Utilizing standard microelectrode stimulation and recording techniques, the electrophysiologic effects of the new antiarrhythmic agent sotalol were studied in Purkinje′s fibers obtained from six nascent mongrel canines (ages 5～15 days) and were compared to changes observed in the adult canine Purkinje′s fibers (n=6). A dose dependent lengthening of the faction potential duration (APD) was observed in the nascent group and the overall increase in APD was significantly greater than that observed in the adult group. Sotalol also produced dose dependent changes in the effective refractory. period (ERP) in both groups though the overall increase in ERP in the nascent group was again greater. We conclude that the immature canine heart appears to be quite sensitive to the class Ⅲactions of sotalol, with changes in APD and ERP being comparable if not greater in magnitude than that observed in the adult.

Hydrological Analysis and Ability Assessing of Flood Gating of Karaj Watershed According to the Form of the Watershed

The numeral trait of aquiferous zones in flowage studies and estimations is under most parts of nation. In this study Karaj aquiferous zone in Alborz province was surveyed from the view point of form, the agglomeration of drainage net length of channel and space. The orientation of hillside was specified as the affective factor on creating and streaming the flowage. A flow aggregating hydrological model for the studied zone was prepared and amount of the flow is mostly in which parts of the zone the delay and centralization time in the zone was evaluated and the related diagrams were derived. Finally, the zone was divided into 4 main subzones and their drainage nets were ranked and by 4 factors namely, space, length of canal, drainage aggregation and branch ratio affecting on performance of the zone from the view of from and appearance was surveyed. The factors interfering in SPSS software and their correlations were specified and specific coefficients stand in their related charts. By considering in the zone width and charts it is specified which of the sub zones has the most flowage potential from the view of the zones physical and numeral qualifications. All plots were prepared using GIS and WMS software and the studied zone’s hydrograph was depicted.

Pressure fluctuation characteristics in the pressurization unit of a multiphase pump

The tip clearance induces the tip leakage vortex(TLV),which has a great impact on the pressure fluctuation characteristics of the multiphase pump.To investigate the effect of the tip clearance on the pressure fluctuations,based on the Reynolds time-averaged Navier-Stokes equation and the shear stress transfer(SST)k-ωturbulence model,the three-dimensional turbulent flow in the pump is numerically simulated for different tip clearances in the water and gas-liquid two-phase cases by using the ANSYS CFX software and the results are verified with experimental data.It is shown the greater pressure fluctuation intensity corresponds with the TLV both in the water and gas-liquid two-phase cases.In the meantime,the location of the maximum pressure fluctuation intensity is related to the tip clearance size.In addition,for different tip clearances,the pressure fluctuation intensity with the rotor and stator interaction(RSI)is relatively larger.The difference is that when R_(tc)=1.5 mm,the pressure fluctuation intensity near the impeller middle point is also relatively larger.On the whole,the pressure fluctuation intensity in the gas-liquid two-phase case is larger than that in the water case.Furthermore,the gas causes the frequency of the high-amplitude pressure fluctuation in the impeller and the diffuser to be shifted from 7 f_(n)(f_(n) denotes impeller rotational frequency)and 3 f_(n) to the low-frequency region,respectively.The pressure fluctuations at the blade-passing frequency(BPF)and the multiple BPFs gradually disappear.Meanwhile,the amplitude at the dominant frequency in the gas-liquid two-phase case is at least one order of magnitude smaller than that in the water case,and the peak-to-peak value of the pressure fluctuation is also much smaller.

From Disintegration to Fragmentation:The Islamic Movement and the al-Inqadh Regime in Sudan

The Islamic Movement of Sudan established the first Islamist regime in the Sunni Islamic world by a military coup.By seising state power,the Islamic Movement tried to overhaul the political system of Sudan.However,what it brought to the politics of Sudan was far from what its leader Hasan al-Turabi envisioned.It was largely due to the failure of the Islamic Movement to institutionalise its control over state power,originating from its design to conceal the nature of the coup which prevented it from claiming the official leadership of the state.The military Islamists leading the coup continued to run the state publicly.The institutions of the Islamic Movement itself were weakened in the process,making it more difficult to lay the national politics on an institutional foundation.The division and conflicts among the Islamists could not be solved in an institutional framework,leading to the split of the Islamic Movement.The Islamists were further fragmented after the split,both within and without the regime,opening the gate for factional politics.

The Nature, Characteristics & Influence of the Drastic Changes in the Middle East

The continuously evolving political turbulences and upheavals of the Arab countries can be regarded as an endogenous Arab democratic movement.In this evolving process,“the Islamic Elements”once again become an important source of spiritual and ideological resources for its social transformation.Now as the situation becomes more and more obvious that various factions of Islamic forces are accelerating their proceedings of“realignment”and“differentiation”,an extremely intrigue complex of interconnections is emerging between different Islamic factions and between religious politics and geopolitics.This situational evolution is not only influencing the Middle East region,but also affecting the peace and development of the whole world.
