Territorial targeting in EU private law

In a series of rulings given in the last few years, the Court of Justice of the European Union (EU) has made use of the concept of targeting by a trader of a particular territorial market as a device for determining the scope of European legislation on private law. The concept is of particular importance in the context of trading activities conducted by means of the Internet, though its significance is not confined to such activities. In particular, the European Court has used the concept of targeting for the purpose of restricting the substantive ambit of intellectual property rights created or harmonised by EU legislation. On the other hand, it has avoided use of the concept of targeting in the context of EU legislation allocating jurisdiction between the courts of the Member States, even in respect of disputes involving intellectual property, except where a legislative text specifically invokes such a concept. The instant paper endeavours to review the position as currently established by the European case-law, and to predict the likely further developments.     

水生态保护与建设的理论问题探讨——以武汉城市圈为视角

自武汉城市圈被评为两型社会综合配套改革实验区以来,面对水环境呈现多样性和复杂性的现状,将武汉城市圈建设成为富有滨水特色的现代化生态城市圈是两型社会建设主题中应有之义,也是推动城市圈生态化发展的必由之路。针对武汉城市圈水生态保护与建设的问题,在阐述了其必然性的基础上,对理论支撑及基本原则作了细致具体的分析,希望能对武汉城市圈水生态保护与建设的实践问题等相关研究有所帮助。     

农业用水及土壤水资源分析研究

在现行水资源评价中,只把地表水和地下水作为水资源看待,但我国华北平原地区降水的70%转化成土壤水,成为农业生产最重要的水源。依据华北平原土壤特性,从农业用水的角度分析了土壤水的水文特征,提出土壤水资源分析研究的建议。     

基于用“动态汛限水位”来利用雨洪资源

雨洪资源的依法利用,早已在国外广泛展开。国内的雨洪资源利用,还面临着重新计算汛限水位高度,然后再依法予以重新确认的难题。唯有如此,才能缓解各级行政部门为了多产粮而＂压＂水库管理部门不顾风险的超汛限蓄水。因此,现阶段用＂动态汛限水位＂来化解矛盾,使水库管理部门从被迫接受潜规则的超汛限蓄水,转变为可以摆上台面的依法科学合理...

基于规则的土壤数据校验模型研究与实现①

数据校验是数据挖掘与知识发现中的重要一环。我国土壤观测数据由于台站观测人员上网条件、观测地记录不便以及需要适当的数据预处理等原因,无法实行在线入库,一般借助于Excel等软件来记录中间结果,再提交土壤分中心,这样的记录过程经常引入不必要的错误。提出了一个基于可定制规则库的土壤数据校验模型。模型主要包括数据格式转换模块、权限管理模块、元数据管理模块、重复记录去除模块、数据校验模块及规则定制与解析模块。低侵入式的轻量级设计,使得在大大减轻数据校验人员工作量的情况下,原有的数据填报流程不需要改变。可定制规则使得模型易于扩展。

control with limited communication and message losses

We propose an H^∞ approach to a remote control problem where the communication is constrained due to the use of a shared channel. The controller employs a periodic time sequencing scheme for message transmissions from multiple sensors and to multiple actuators of the system. It further takes into account the information on the random message losses that occur in the channel. An exact characterization for controller synthesis is obtained and is stated in terms of linear matrix inequalities. Furthermore, an analysis on the loss probabilities of the messages to accomplish stabilization is carried out. The results are illustrated through a numerical example.     

A Level-Set Method for Computing the Eigenvalues of Elliptic Operators Defined on Compact Hypersurfaces

We demonstrate, through separation of variables and estimates from the semi-classical analysis of the Schrödinger operator, that the eigenvalues of an elliptic operator defined on a compact hypersurface in ? ⁿ can be found by solving an elliptic eigenvalue problem in a bounded domain Ω?? ⁿ . The latter problem is solved using standard finite element methods on the Cartesian grid. We also discuss the application of these ideas to solving evolution equations on surfaces, including a new proof of a result due to Greer (J. Sci. Comput. 29(3):321–351, 2006).
