Decentralized Stabilization of Large-scale Uncertain Systems with State-Delays——LMIs Approach

This paper deals with the problem of decentralized robustcontrol for a class of interconnected uncertain systemswith state delays.The parameter uncertainties are un-known but norm-bounded.A new sufficient condition isobtained for each subsystem and overall system to be sta-bilizable via linear memoryless state feedback robust de-centralized controllers.The results depend on the size of the delays and are given in terms of linear matrix ine-qualities,so they are less conservative than those of delay-independent.Moreover,matching condition is not a necessary condition.Finally,an example is presented to illustrative the effectiveness of the proposed method.

Utilization Survey of Livestock Manure Resources in Large-scale Farms of Yangzhou

Based on surveying the conditions of large -scale farms and commercial manure in the each county of Yangzhou city, the situations and problems for utilization of livestock manure resources were grasped. After an analysis of the potential value of livestock manure, the suggestion and strategy for utilization of livestock manure resources were proposed based on the actual conditions in Yangzhou city.

Formation conditions and exploration direction of large natural gas reservoirs in the oil-prone Bohai Bay Basin, East China

The Bohai Bay Basin is a typical oil-prone basin, in which natural gas geological reserves have a small proportion. In this basin, the gas source rock is largely medium-deep lake mudstone with oil-prone type Ⅱ2-Ⅱ1 kerogens, and natural gas preservation conditions are poor due to active late tectonic movements. The formation conditions of large natural gas fields in the Bohai Bay Basin have been elusive. Based on the exploration results of Bohai Bay Basin and comparison with large gas fields in China and abroad, the formation conditions of conventional large-scale natural gas reservoirs in the Bohai Bay Basin were examined from accumulation dynamics, structure and sedimentation. The results show that the formation conditions of conventional large natural gas reservoirs in Bohai Bay Basin mainly include one core element and two key elements. The core factor is the strong sealing of Paleogene "quilt-like" overpressure mudstone. The two key factors include the rapid maturation and high-intensity gas generation of source rock in the late stage and large scale reservoir. On this basis, large-scale nature gas accumulation models in the Bohai Bay Basin have been worked out, including regional overpressure mudstone enriching model, local overpressure mudstone depleting model, sand-rich sedimentary subsag depleting model and late strongly-developed fault depleting model. It is found that Bozhong sag, northern Liaozhong sag and Banqiao sag have favorable conditions for the formation of large-scale natural gas reservoirs, and are worth exploring. The study results have important guidance for exploration of large scale natural gas reservoirs in the Bohai Bay Basin.

AN ADAPTIVE CONTROL STRATEGY FOR PROPER MESH DISTRI-BUTION IN LARGE EDDY SIMULATION

The Filtering Grid Scale （FGS） of sub-grid scale models does not match with the theoretical Proper FGS （PFGS） because of the improper mesh. Therefore, proper Large Eddy Simulation （LES） Mesh is very decisive for better results and more economical cost. In this work, the purpose is to provide an adaptive control strategy for proper LES mesh with turbulence theory and CFD methods. A new expression of PFGS is proposed on the basis of -5/3 law of inertial sub-range and the proper mesh of LES can be built directly from the adjustment of RANS mesh. A benchmark of the backward facing step flow at Re = 5147 is provided for application and verification. There are three kinds of mesh sizes, including the RANS mesh, LAM （LES of adaptive-control mesh）, LFM （LES of fine mesh）, employed here. The grid number of LAM is smaller than those of LFM evidently, and the results of LAM are in a good agreement with those of DNS and experiments. It is revealed that the results of LAM are very close to those of LFM. The conclusions provide positive evidences for the novel strategy.

食品大规模侵权损害多元化救济制度论析

当前,食品大规模侵权事件时有发生,究其原因主要在于食品大规模侵权损害的民事救济制度不足、社会救济制度薄弱、行政救济制度不合理。各救济制度在实践中的局限性严重阻碍其功能的充分发挥。因此应完善代表人诉讼制度和惩罚性赔偿制度,建立责任保险制度和补偿基金制度,落实行政救济制度。通过多元化救济制度,减轻法院诉讼负担,保障受害者权利,维护社会稳定。

现代化通信工具大规模侵权惩罚性赔偿制度构建

现代化通信工具在带给人们无限便利的同时,也为侵权者的侵权带来了效率。但面对以损害波及面大、个体侵权数额小、侵权主体隐蔽为特点的现代化通信工具大规模侵权,我国现行侵权责任法颇感力不从心。美国于二十世纪九十年代产生的现代化通信工具大规模侵权的惩罚性赔偿制度,历经几十年的审判实践验证具有极为显著的制度优势。惩罚性赔偿制度不仅可以填补侵权行为造成的一般侵权责任无法填补的社会整体利益的损害,而且能够激励受害人积极主张权利,并且以最小的成本遏制恶性的侵权行为。惩罚性赔偿制度的构建需要设立开放性和指导性的一般条款,明确现代化通信工具大规模侵权的认定标准,并应赋予现代化通信工具运营商不真正连带责任。

大型体育赛事赛会志愿者的地位及其相关法律责任

大型体育赛事赛会志愿者是赛事组委会或志愿者组织的受托人。这是赛会志愿者基于委托合同具有的基本法律地位,并决定了其与赛事组委会或志愿者组织之间的合同责任性质和具体内容,也影响着他们和志愿服务对象之间法律责任的承担方式。

大规模侵权救济问题研究

大规模侵权责任须符合侵权责任构成要件,可以被纳入侵权责任法的调整范围,且受害者众多,发生原因同一或同质,救济困难。从我国法制环境看,产品责任、药品责任和环境污染责任是主要的大规模侵权责任类型。目前对此种侵权损害的救济方式主要有大规模侵权损害救济基金、责任保险、惩罚性赔偿和举证责任倒置及连带赔偿责任。对于此四种救济方式而言,法技术上的可为之处主要在于认定此类侵害行为与损害结果之间的因果关系及被告之间的责任承担。在因果关系的认定上,应适用举证责任倒置规则,由被告证明其行为与损害没有因果关系。在责任承担上,由加害者在无法反证其不应承担责任的情形下,对受害者承担连带责任。

浅析大规模产品侵权的举证责任——以“三鹿奶粉事件”为分析案例

"三鹿奶粉事件"引起人们对大规模产品侵权问题的思考,而我国法律并未就大规模产品侵权问题作出规定。基于大规模产品侵权的特殊性分析,应该在大规模产品侵权举证责任分配方面为众多的受害人提供充分的、及时的救济,由政府为受害人提供产品缺陷举证责任上的帮助,并且实行因果关系推定。

Probing dynamics of dark energy with latest observations

We examine the validity of the ACDM model and probe the dynamics of dark energy with the latest astronomical observations. Using the Ore（z） diagnosis, we find that various kinds of observational data are in tension within the ACDM framework. We then allow for dynamics of dark energy and investigate the constraint on dark energy parameters. We find that for two different kinds of parametri- sations of the equation of state parameter w, a combination of current data mildly favours an evolving w, although the significance is not sufficient for it to be supported by Bayesian evidence. A forecast of the DESI survey shows that the dynamics of dark energy could be detected at the 7σ confidence level and would be decisively supported by Bayesian evidence, if the best-fit model of w derived from current data is the true model.

我国大规模侵权的法律问题及救济机制研究

随着社会工业化程度的发展和社会物质生活水平的提高,大规模侵权现象日渐增多,呈现出侵权类型多样、损害后果严重、救济途径有限等特点。司法实践中,大规模侵权的法律规定存在空白,处理机制有待完善。基于此,在借鉴英美法系国家,如美国和英国关于大规模侵权的实体法律问题及其救济机制相关研究的基础上,总结、梳理我国大规模侵权的实体法律适用及救济机制研究,以期有助于司法实践。

风险社会大规模损害责任法的范式重构——从侵权赔偿到成本分担

风险社会是人类利用科技从事创造活动而产生的人为风险成为影响人类生活乃至生存和发展的主要因素的社会,如何缓解与分配风险损害成为风险社会的核心问题。风险社会的大规模损害以事故型和累积型大规模公害为主导。侵权法解决的损害问题是私人对私人利益的侵害,其主要功能在于补偿受害者,其制度运行有赖于损害的确定性、有限性、可计量性、可预期和可控制性、私人性。风险损害所具有的不确定性、无限性、不可计量性、不可预期性、不可控制性和社会公共性颠覆了这些条件,对风险损害主要以规制法予以事前防范。规制法防治私人对公共利益的侵害,其主要通过事前预防责任的分担降低风险损害,事后责任作为补充。规制法责任的实质是对风险成本的分担。分担应遵循社会分担、有效分担、平衡分担以及预防为主、救济为辅的原则。规制法的责任制度包括预防责任和补救责任。
