共享自动驾驶汽车使用意愿模型及其影响因素

为了构建共享自动驾驶汽车(shared autonomous vehicles，SAV) 的使用意愿模型并分析其影响因素，通过使用时机和使用频率来体现公众对SAV的使用意愿；采用验证性因子分析将态度潜变量转化为潜变量得分，以此将态度潜变量引入传统的有序Logit模型；提出SAV使用意愿的有序Logit模型构建方法，并建立基于个人属性、通勤特征、态度潜变量的SAV使用意愿模型.研究发现:是否使用过滴滴拼车、工作单位停车费、自动驾驶态度对使用时机和3种价格(1，2，3元/km) 下的使用频率有显著影响；使用过滴滴拼车、工作单位收取停车费、支持自动驾驶的群体倾向于频繁地、更早地使用SAV出行；公众期望以1元/km或 2元/km即不超过目前滴滴拼车的价格使用SAV.

论中国儒家思想中人的发展观

从狭义上讲，人的发展观是关于个体人的发展的最根本的看法。中国传统社会中儒家思想的人的发展观就是在这个意义上讨论的，它着重把人的发展的本质内容理解为人的道德修养。这种人的发展观的形成有其深刻的社会经济根源和政治基础。

本文对具有有限时滞的泛函微分方程建立了关于依照两种测度的实际稳定性的Razumikhin型判定定理，其中未采用通常的辅助函数，且可运用多个含有状态变量x的部分变元的Lyapunov函数，得出部分变远实际稳定性的判定定理，从而改进了已有的结果。     

Jane Eyre,a Plain but Spectacular semi-autobiographic Portrait of Charlotte Bronte

Maybe life itself is a endured suffering. This is a story about a special and unreserved woman who has been exposed to a hostile environment but continuously and fearlessly struggling for her ideal life. It is interpreted as a symbol of the independent spirit.Through Jane Eyre,Charlotte Bronte realized her own dream and life pursuit.There she was the master of her own fate.     

邓小平对中美关系的论述及其现实意义

1977年邓小平复出后十分重视中美关系,在他亲自领导下,中美关系有了很大的发展,其间,也经历了许多波折。邓小平对中美关系的重要性有正确的判断,对存在的问题有清醒的认识,对中美关系的斗争性有充分的准备。回顾邓小平对中美关系的论述,在当前中美关系依然错综复杂的情况下,有助于我们正确把握中美关系的航向,有助于中美关系健康稳定发展。

The detection of structural deformation errors in attitude determination

In the determination of the attitude parameters from a multi-antenna GPS array, one of the major assumptions is that the body frame is rigid at all times. If this assumption is not true then the derived attitude parameters will be in error. It is well known that in airborne platforms the wings often experience some displacement during flight, especially during periods of initializing maneouvres, such as taking off, landing,and banking. Often it is at these points in time that it is most critical to have the most precise attitude parameters.There are a number of techniques available for the detection of modeling errors.The CUSUM algorithm has successfully been implemented in the past to detect small persistent changes. In this paper the authors investigate different methods of generating the residuals, to be tested by the CUSUM algorithm, in an effort to determine which technique is best suited for the detection of structural deformation of an airborne platform. The methods investigated include monitoring the mean of the residuals generated from the difference between the known body frame coordinates, and those calculated from the derived attitude parameters. The generated residuals are then passed to a CUSUM algorithm to detect any small persistent changes. An alternative method involves transforming the generated residuals into the frequency domain through the use of the Fast Fourier Transform. The CUSUM algorithm is then used to detect any frequency changes. The final technique investigated involves transforming the generated residuals using the Haar wavelet. The wavelet coefficients are then monitored by the CUSUM algorithm in order to detect any significant change to the rigidity of the body frame.Detecting structural deformation, and quantifying the degree of deformation, during flight will ensure that these effects can be removed from the system, thus ensuring the most precise and reliable attitude parameter solutions. This paper, through a series ofsimulations, will assess the effectiveness of the above mentioned techniques for detecting structural deformation effects on a GPS multi-antenna array. These principles are then tested with experimental data.     

论艺术概括的基本方式和三个层次

艺术概括是塑造优秀文学形象的重要手段 ,它的基本方式是必须融会在个性书写过程中 ,以个性书写为形态。艺术概括包涵三个由浅入深的层次 ,即 ( 1)通过个性概括同类现象的共同特征 ;( 2 )通过个性深入揭示内在本质 ;( 3 )通过个性显示深广的社会意义。达到这三个层次 ,文学形象便可获得深厚的内在意蕴
