We are living in an inter-connected, global digital society where the services of different operating systems are universal in nature, but many Internet activities are still being tackled by national laws and regulations. A long-existing question is which law is applicable in cases of Internet activities because the online world does not have any physical boundaries. How the European Union (EU) approaches this duality has become a concern for data protection laws. By analysing some recent Court of Justice of the European Union case laws, this article seeks to discover how the EU data protection law tackles disputes involving transnational issues online, which includes its extra-territorial application and cross-border data transfers. The article also indicates that there is an enormous gap between legislation and practice. 相似文献

In this paper we propose a compact split step Padé scheme (CSSPS) to solve the scalar higher-order nonlinear Schrödinger equation (HNLS) with higher-order linear and nonlinear effects such as the third and fourth order dispersion effects, Kerr dispersion, stimulated Raman scattering and power law nonlinearity. The stability of this method has been proved. It has been shown as well that the CSSPS method gives the same results as classical numerical methods like the split step Fourier method and Crank–Nicholson (CN) method but it presents many advantages over theme. It is more efficient. This proposed scheme is well suited to higher-order dispersion effects and readily generalized for nonlinear and dispersion managed fibers. We tested this scheme for the case of the quintic nonlinearity and confirmed that this effect has no significant role on the propagation of single solitons. 相似文献

Legal reasoning with subjective logic 总被引:1,自引:0,他引:1
Judges and jurors must make decisions in an environment of ignoranceand uncertainty for example by hearing statements of possibly
unreliable ordishonest witnesses, assessing possibly doubtful or irrelevantevidence, and enduring attempts by the opponents
to manipulate thejudge's and the jurors' perceptions and feelings. Three importantaspects of decision making in this environment
are the quantificationof sufficient proof, the weighing of pieces of evidence, and therelevancy of evidence. This paper proposes
a mathematical frameworkfor dealing with the two first aspects, namely the quantification ofproof and weighing of evidence.
Our approach is based on subjectivelogic, which is an extension of standard logic and probability theory,in which the notion
of probability is extended by including degrees ofuncertainty. Subjective Logic is a framework for modelling humanreasoning
and we show how it can be applied to legalreasoning. 相似文献

数字X射线图象的形成是一个X射线信息影象的形成、转换和传递的复杂过程,且通常得到的数字X射线图象的灰度值没有准确的物理意义,在实验的基础上,提出了一种基于朗伯定律的理想图象模型,用以对数字X射线图象进行灰度的校正及线性化,经过这样的处理后,图象的灰度值与吸收体厚度之间的关键近似为线性,这对于人体特征参数的定量分析(如对心脏形态、血流的分析,以及在DSA中对造影剂浓度的分析等)具有重要作用。 相似文献

"任务驱动法"是建立在建构主义教学理论基础上的教学法,作为建构者——教师,仅是学习的指导者、辅助者、咨询者、导航者,而学生才是教与学活动中的主体,在具体教学过程中,我们应将大量时间留给学生带着驱动"任务"进行研究性学习。目前,我国中学信息技术课程中普遍采用这一教学法,即在具体教学过程中,我们应尽量压缩教师讲授内容的时间,而将大量的时间留给学生进行研究性学习。本文就如何优化信息技术课程谈几点思考。 相似文献

In this paper an adaptive guidance law based on the characteristic model is designed to track a reference drag acceleration for reentry vehicles like the Shuttle. The characteristic modeling method of linear constant systems is extended for single-input and single-output (SlSO) linear time-varying systems so that the characteristic model can be established for reentry vehicles. A new nonlinear differential golden-section adaptive control law is presented. When the coefficients belong to a bounded closed convex set and their rate of change meets some constraints, the uniformly asymptotic stability of the nonlinear differential golden-section adaptive control system is proved. The tracking control law, the nonlinear differential golden-section control law, and the revised logical integral control law are integrated to design an adaptive guidance law based on the characteristic model. This guidance law overcomes the disadvantage of the feedback linearization method which needs the precise model. Simulation results show that the proposed method has better performance of tracking the reference drag acceleration than the feedback linearizaUon one. 相似文献

In this article the suggested permit and licence systems included in the draft Afghan Water Law of 2008 (superseding those laws of 1981 and 1991) are examined by comparing them with main canal data from two pilot studies within the Kunduz Basin. The comparison highlights the difficulty of making these proposed legal frameworks operative. Overall, it appears that the sections within the law on permits and licences are not implementable within or even useful for the traditional irrigation systems, but mainly play into the hands of the national hydrocracy and please international donors. 相似文献
