如今,准确及时的短期交通情况预测对智能交通系统有着重要意义。交通网络中的车速预测是智能交通系统的重要组成部分。准确及时的车速预测可以支撑交通管理,改善交通状况。然而大规模网络范围内的交通速度预测是一项具有挑战性的任务,原因是道路网络的计算复杂性、交通堵塞在长时间上的传播以及交通数据中的空间相关性。近年来,基于深度学习的方法在交通预测中显,示出了其优越性。这些方法能够有效地捕捉路网复杂的空间相关性和非线性交通状况。然而,从模型结构的深度、预测区域的空间尺度和预测能力的角度来看,这些时空数据尚未在交通预测中得到充分的利用。因此,为了克服上述问题,本文提出了一种基于深度学习的交通网络速度预测结构Att BDLSTM-FCN,该结构基于全卷积神经网络、双向长短期记忆和注意力机制,考虑双向空间特征和时间关系,去预测交通网络的车速。在该模型中,使用FCN增强了基于注意力的双向LSTM预测能力。通过大规模真实数据集上的实验,本文模型优于现有的最新模型。另外,我们提出的模型也可以预测多个阶段的交通速度。

关于贸易与增长关系的讨论并不简单。长期来看,贸易会促进经济增长和繁荣,但增长质量和数量之间存在广泛的非一致性,在增长质量层面贸易是否产生了积极的作用?本研究分析了贸易对发展中国家经济增长质量的影响。主要目标国家是非洲,拉丁美洲和亚太地区,使用(1990-2009)的面板数据。本研究从三个指标衡量经济增长的质量:效率,稳定性和增长的可持续性。我通过主成分分析法(PCA)测算经济增长的综合质量指标和增长效率、稳定性、可持续性3个分类质量指标。然后利用静态和动态面板考察了国际贸易对增长质量的作用,并考察了政府干预的影响。实证结果表明,贸易并不直接影响经济增长质量,但政府干预会改善贸易的作用,联合项对经济增长质量产生积极和显著增强。在分类指标回归中,贸易和政府干预在增长效率,稳定性和可持续性渠道也产生了积极作用。

The ceramic composites of sodium bismuth titanate with reduce graphene oxide NBT/rGO of different compositions were fabricated by solid state sintering method and characterized. In this work, the graphene oxide (GO) and reduce graphene oxide (rGO) was successfully synthesized by Hummer’s modified method which is confirmed by FTIR and XRD results. The reduce graphene oxide used as 2D filler in piezoelectric creamic material. The crystalline structure of NBT/rGO composite was confirmed by X-ray diffraction with rhombohedral symmetry. The dispersion of rGO in the ceramic can be detect by the optical microcopy images. The electrical conductivity of sodium bismuth titanate shows increase at higher values of frequency and conductivity nanocomposites of different wt% were start decreases up to certain value of frequency. The broadening of peaks in frequency explicit plots of electrical conductivity with the help of LCR Meter (Impedance Capacitance and Resistance). The crystalline size of reduced graphene oxide and NBT is calculated by Scherrer’s formula of XRD peaks.

Violence comes first by which human lives are being destroyed. Violence poses serious challenges to law enforcement agencies and policy makers as well as it threatens the writ of the Government. Violence condition of a country can be visualized through an accurate violence risk map. This paper presents the methodology to develop an incidence of violence (IOV) risk map using GIS. IOV data for year 2010 was collected from Pakistan Institute for Peace Studies (PIPS) that have 3104 records and cover 16 categories of attack types. IOV data was further geocoded by using online Google geocoding service. IOV risk maps were developed through two available methods: kernel density and getis-ord-gi* by giving single parameter “frequency”, and one new indexing method by giving two additional parameters as well “severity” and “probability”. For each district, IOV frequency and IOV severity values were calculated from PIPS data whereas IOV probability value was derived from the Benazir Income Support Program—Poverty Scorecard Survey (BISP—PSS). A value ranging from 1 to 5 was assigned to each of three parameters against each district and then all three parameters were multiplied with each other to generate IOV risk index that had values ranging from 1 to 125. IOV risk index was further classified through natural breaks into three categories: low risk (1 - 40), moderate risk (41 - 70) and high risk (71 - 125). For validation purpose, spatial overlay analysis was conducted between year 2011 IOV data (classified through natural breaks) and year 2010 IOV risk maps (developed through kernel density, getis-ord-gi* and indexing method). The indexing method has proved as a reliable method to develop an IOV risk map with an accuracy of 93 percent then getis-ord-gi* and kernel density having accuracy of 58 percent and 89 percent respectively. Furthermore, indexing method predicted IOV risk areas more efficiently in terms of spatial distribution. Indexing method highlighted Khuzdar, Zhob, Up

本论文主要关注如下问题:在许多未标记的人脸图像数据集中,将人脸图像聚类成数据中存在的不同身份。该问题在社交媒体和司法鉴定时有着广泛的应用。近些年来,视频监控在许多领域得到了广泛的关注,包括司法鉴定,公共安全,交通控制和住宅监控等。如今,警方通过从视频监控所拍摄的视频或照片来对犯罪分子进行搜查。然而,人工从视频中找到相关目标将会耗费大量的人力和物力,进而促进了自动化的发展。本文将重点研究基于密度的噪声应用空间聚类(DBSCAN)算法,该方法是一种高效且有效的方法,具有良好的性能,并且取得比其他聚类方法(如,k-means,谱聚类和Rank-Order)更高的精度。基于密度的聚类算法DBSCAN的核心思想是聚类中的每个对象必须在其邻域内具有一定数量的其他对象。与其他聚类算法相比,DBSCAN具有许多优点,例如,它可以检测任意形状的聚类,并且对异常值等具有鲁棒性。因此,DBSCAN在过去几十年中引起了很多研究兴趣,并且有着许多扩展和应用。本文将研究五种不同的聚类算法,并在不同数据集上进行测试。五种聚类算法是k-means,threshold clustering,mean shift,DBSCAN和rank-order。在第一个实验中,本文将这些聚类方法在LFW子集和全集上进行测试。本文还在ISIS人脸数据集上进行测试,以评估这些聚类算法的性能。本文通过实验发现,threshold clustering在F-measure和误报数量上有着非常好的性能。除此之外,DBSCAN在整个实验过程中都取得了较好的效果。因此,DBSCAN是一种高效的人脸聚类方法.
