On the Probability Density Function of the Real and Imaginary Parts in WFRFT Signals

引用

China Communications 2016年第9期13卷 44-52页

作者： xiaolu wang Lin Mei Zhenduo wang Naitong Zhang Communications Research Center School of Electronics and Information EngineeringHarbin Institute Technology

Recently a Hybrid Carrier （HC） scheme based on Weighted-type Fractional Fourier Transform （WFRFT） was proposed and developed, which contains Single Carrier （SC） and Multi-Carrier （MC） synergetie transmission. The wide interest is primarily due to its appealing characteristics, such as the robust performances in different types of selective fading channels and a great deal of potential for secure communications. According to the literatures, the HC signal and SC or MC signal probability distributions are different. In particular, some benefits of this HC scheme are brought by the quasi-Gaussian distribution of WFRFT signals. However, until now researchers have only presented statistic properties through computer simulations, and the accurate expressions of signals are not derived yet. In this paper, we derive the accu- rate and rigorously established closed-form expressions of Probability Density Function （PDF） of WFRFT signal real and imaginary parts with a large number of QPSK subcarriers, and this PDF can describe the behavior of data modulated by WFRFT, avoiding the complex computation for extensive computer simulations. Furthermore, the components of PDF expression are described and analyzed, and it is revealed that the tendency of signal quasi-Gaussian changes with the increasing of the parameter a （a in （0,1]）. To validate the analytical results, extensive simulations have been conducted, showing a very good match between the analytical results and the real situations. The contribution of this paper may be useful to deduce the closed form expressions of Bit Error Ratio （BER）, the Complementary Cumulative Distribution Function （CCDF） of Peak to Average Power Ratio （PAPR）, and other analytical studies which adopt the PDF.

Comparison of predicting drag methods using computational fluid dynamics in 2d/3d viscous flow

Science China(Technological Sciences) 2007年第5期50卷 534-549页

As a result of the necessity of aircraft engineering design and the progress of computational fluid dynamics (CFD), techniques of accurately predicting aero- dynamic drag are being increasingly explored. According to the momentum bal- ance, the drag can be represented by an integral over a cross-flow plane (called wake integration method) at an arbitrary distance behind the configuration. A for- mulation to reduce the size of the wake cross plane region required for calculating the drag is developed by using cutoff parameters of vorticity and entropy. This in- creases the calculation accuracy and decreases the computation time required. Numerical experiments are made to obtain the threshold values of these cutoff pa- rameters. The wake integration method is applied to predict drags of some exam- ples including airfoil, a variety of wings and wing-body combination. Numerical results are compared with those of traditional surface integration method, showing that the predicting drag values with the wake integration method are closer to the experimental data. The results also show that drag prediction within engineering accuracy is possible by using CFD and the numerical drag optimization of complex aircraft configurations is possible, too.

Comparison of two design methods of aerodynamic biobjectives for airfoil and wing shapes

Science China(Technological Sciences) 2004年第2期47卷 203-215页

A simplified adaptive wing, which deflects its leading edge and trailing edge flaps to vary its shape, is calculated to investigate the potential aerodynamic gains and compared with a biobjective optimization (BO) wing in the present paper. In subsonic-transonic flights the deflection angle of a flap is determined through optimization using a deterministic method. In supersonic flight the flaps are not deflected due to the requirement of having a minimum drag. For comparison the aerodynamic characteristics of a BO airfoil and wing is calculated. A parallel genetic algorithm is used in BO. Euler equations served as governing equations in flow field calculation. Numerical results in both 2D (airfoil) and 3D (wing) cases show that aerodynamic performances of the two design airfoils and wings are much better than those of the original ones, with the adaptive design one the best. Keywords simplified adaptive wing - biobjective optimization - airfoil and wing design

Three-Dimensional Modelling of a Multi-Layer Sandstone Reservoir： the Sebei Gas Field, China

引用

Acta Geologica Sinica(English Edition) 2016年第1期90卷 209-221页

作者： OU Chenghua wang xiaolu LI Chaochun HE Yan State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation Southwest Petroleum UniversityChengdu 610500SichuanChina Natural Gas Exploitation Company of Qinghai Oilfield CNPCGolmud 816000QinghaiChina Auditing Department Southwest Petroleum UniversityChengdu 610500SichuanChina

Multi-layer sandstone reservoirs occur globally and are currently in international production. The 3D characteristics of these reservoirs are too complicated to be accurately delineated by general structural-facies-reservoir modelling. In view of the special geological features, such as the vertical architecture of sandstone and mudstone interbeds, the lateral stable sedimentation and the strong heterogeneity of reservoir poroperm and fluid distribution, we developed a new three-stage and six-phase procedure for 3D characterization of multi-layer sandstone reservoirs. The procedure comprises two-phase structural modelling, two-phase facies modelling and modelling of two types of reservoir properties. Using this procedure, we established models of the formation structure, sand body structure and microfacies, reservoir facies and properties including porosity, permeability and gas saturation and provided a 3D fine-scale, systematic characterization of the Sebei multi-layer sandstone gas field, China. This new procedure, validated by the Sebei gas field, can be applied to characterize similar multi-layer sandstone reservoirs.

Visual Information Based Social Force Model for Crowd Evacuation

Tsinghua Science and Technology 2022年第3期27卷 619-629页

With the increase in large-scale incidents in real life, crowd evacuation plays a pivotal role in ensuring the safety of human crowds during emergency situations. The behavior patterns of crowds are well rendered by existing crowd dynamics models. However, most related studies ignore the information perception of *** overcome this issue, we develop a visual information based social force model to simulate the interpretable evacuation process from the perspective of visual perception. Numerical experiments indicate that the evacuation efficiency and decision-making ability promote rapidly within a small range with the increase in unbalanced prior knowledge. The propagation of acceleration behavior caused by emergencies is asymmetric due to the anisotropy of visual information. Therefore, this model effectively characterizes the effect of visual information on crowd evacuation and provides new insights into the information perception of individuals in complex scenarios.

China's Urban Employment and Urbanization Rate:A Re-estimation

引用

China & World Economy 2014年第1期22卷 30-44页

作者： xiaolu wang Guanghua Wan National Economic Research Institute Asian Development Bank

The present paper argues that China＇s existing population and employment statistics are misleading, and have failed to include many of the migrant and labor force flows between urban and rural areas. The paper reconciles the differences between official census data and other survey statistics and attempts to recalculate China＇s urban population and employment figures. Our analyses indicate that official statistics of 2012 underestimate China ＇s urban employment by approximately 47 million while overestimating rural employment by 31 million. The adjusted urbanization rate exceeded 55 percent in 2012, almost 3 percentage points higher than the official statistics. Nevertheless, there remains much potential for rural-to-urban migration. More specifically, if the current bottlenecks in household registration, social security and public welfare systems can be removed or relaxed, China＇s urbanization rate could rise by another l O percentage points or even more over the next decade.
