我们需要什么样的地域主义

因应"大同文化"的负面影响,"地域主义"在现在的中国已经深入人心,但"地域主义"于中国的实践,一直以来没有什么标准可循,对于地域文化的继承也似乎停留在拼凑临摹传统符号上,浪漫之余略显苍白无力,甚至于直接遁入绝对的"历史主义",这是值得我们注意的现象。本文尝试通过对"批判的地域主义"理论的研究,阐述我们需要什么样的"地域主义"这个问题。

Stability of nonlinear hybrid dynamical systems with time delay via sum of squares decomposition

Considering an infinite number of eigenvalues for time delay systems, it is difficult to determine their stability. We have developed a new approach for the stability test of time delay nonlinear hybrid systems. Construction of Lyapunov functions for hybrid systems is generally a difficult task, but once these functions are found, stability’s analysis of the system is straight-forward. In this paper both delay-independent and delay-dependent stability tests are proposed, based on the construction of appropriate Lyapunov-Krasovskii functionals. The methodology is based on the sum of squares decomposition of multivariate polynomials and the algorithmic construction is achieved through the use of semidefinite programming. The reduction techniques provide numerical solution of large-scale instances; otherwise they will be computationally infeasible to solve. The introduced method can be used for hybrid systems with linear or nonlinear vector fields. Finally simulation results show the correctness and validity of the designed method.

利用MODIS EVI时间序列数据分析福建省植被变化(2000~2017年)

以全国森林覆盖率最高的福建省为研究对象,利用2000~2017年夏季的MODIS EVI植被指数数据和气象与非气象因子进行协同分析,以揭示近17年福建植被的时空变化及其影响因子。结果表明:研究期内福建的EVI均值整体上升,从2000年的0.454上升至2017年的0.505,17 a间上升了11.2%,表明福建省的植被整体处于变好的状态,且在中部和西南部的变化最明显。相关分析表明,在研究期内,气象因子(气温和降水)对EVI变化的影响不显著,植被的变好主要为非气象因子的作用。EVI的提高主要得益于2003年福建省建设生态省后森林覆盖率的提高,并和2012年开始的水土流失治理有明显关系,这说明人类活动的积极作用对福建植被的变好起到了关键的作用。     

INTRODUCTION TO THE SPECIAL ISSUE ON CASE-BASED REASONING IN THE HEALTH SCIENCES

There has been an explosion of interest in health sciences applications of case-based reasoning (CBR), not only in the traditional CBR in medicine domain, but also in bioinformatics, enabling home health-care technologies, CBR integration, and synergies between CBR and knowledge discovery. This special issue features the best papers from the third workshop on CBR in the health sciences, held at ICCBR-05 in Madrid. It is the third in a series of exciting workshops, the first two of which were held at ICCBR-03, in Trondheim, Norway, and at ECCBR-04, in Madrid, Spain. The nine high-quality papers introduced here represent the research and experience of twenty-two authors working in eight different countries on a wide range of problems and projects. These papers illustrate some of the major trends of current research in CBR in the health sciences, and represent overall an excellent sample of the most recent advances of CBR in the health sciences.     

Analysis of finite-buffer discrete-time batch-service queue with batch-size-dependent service

Over the last two decades there has been considerable growth in digital communication systems which operate on a slotted system. In several applications, transmission of packets over the network takes place in batches of varying size, and transmission time depends upon the size of the batch. Performance modelling of these systems is usually done using discrete-time queues. In view of this, we consider a single-server queue with finite-buffer in a discrete-time domain where the packets are transmitted in batches (of varying size) according to minimum and maximum threshold limit, usually known as general batch service rule. The transmission time (in number of slots) of these batches depends on the number of packets within the batch under transmission, and is arbitrarily distributed. We obtain, in steady-state, distribution of the number of packets waiting in the queue and in service (those being transmitted in batches). In addition, we also obtain average number of packets waiting in queue, in the system, with the server, rejection probabilities, etc. Finally, computational experiences with a variety of numerical results have been discussed by introducing a cost model which gives optimum value of the lower threshold limit.     

社交网络中的社团结构挖掘

社交网络已经成为现代人们在线交流并交换信息的重要途径之一。以国内的人人网为例,大量的年轻人,尤其是学生,以此为平台,相互讨论感兴趣的话题。人与人之间因为学习关系、工作关系、共同的兴趣等诸多因素关联起来;以大学生交流为主体的社交网则更有可能因为在相同院、系、所而关联在一起,从而呈现出社团结构。该文以人人网的真实数据,使用CNM算法来验证这一假设;同时,还利用社会网络的结构知识对CNM算法作了改进,提高了社团发现的精度。所挖掘的社团结构关系还表明,高校不同院系和学科形成的社团具有各自的特点。     

Design and analysis of the Dual-Torus Network

In this paper, we propose a new topology called theDual Torus Network (DTN) which is constructed by adding interleaved edges to a torus. The DTN has many advantages over meshes and tori such as better extendibility, smaller diameter, higher bisection width, and robust link connectivity. The most important property of the DTN is that it can be partitioned into sub-tori of different sizes. This is not possible for mesh and torus-based systems. The DTN is investigated with respect to allocation, embedding, and fault-tolerant embedding. It is shown that the sub-torus allocation problem in the DTN reduces to the sub-mesh allocation problem in the torus. With respect to embedding, it is shown that a topology that can be embedded into a mesh with dilation δ can also be embedded into the DTN with less dilation. In fault-tolerant embedding, a fault-tolerant embedding method based on rotation, column insertion, and column skip is proposed. This method can embed any rectangular grid into its optimal square DTN when the number of faulty nodes is fewer than the number of unused nodes. In conclusion, the DTN is a scalable topology well-suited for massively parallel computation.

空域频域相结合的唇型篡改检测方法

近年来,社交网络中的“换脸”视频层出不穷,对说话者进行唇型篡改是其中的视频代表之一,这给大众生活增添娱乐的同时,对于网络空间中的个人隐私、财产安全也带来了不小隐患。大多数唇型篡改检测方法在无损条件下取得了较好的表现,但广泛存在于社交媒体平台、人脸识别等场景中的压缩操作,在节约像素和时间冗余的同时,会对视频质量造成影响,破坏空域上像素与像素、帧与帧之间的连贯完整性,导致其检测性能的下降,从而引发对真实视频的错判情况。当空域信息无法提供足够有效的特征时,能够抵抗压缩干扰的频域信息就自然而然地成为重点研究对象。针对这一问题,通过分析频率信息在图像结构和梯度反馈上的优势,提出了空域频域相结合的唇型篡改检测方法,有效利用空域、频域信息的各自特点。对于空域上的唇型特征,设计了自适应提取网络和轻量级的注意力模块;对于频域上的频率特征,设计了不同分量的分离提取与融合模块。随后,通过对空域上的唇型特征和频域上的频率特征进行有侧重的融合,保留更多关键纹理信息。此外,在训练中设计细粒度约束,分开真假唇型特征类间距离的同时,拉近类内距离。实验结果表明,得益于频率信息,所提方法能有效改善压缩情况下的检测准确性,...
