Recent years have witnessed the expeditious evolution of intelligentsmart devices and autonomous software technologies with the expandeddomains of computing from workplaces to smart computing in everydayroutine life activities. This trend has been rapidly advancing towards the newgeneration of systems where smart devices play vital roles in acting intelligently on behalf of the users. Context-awareness has emerged from the pervasive computing paradigm. Context-aware systems have the ability to acquirecontextual information from the surrounding environment autonomously,perform reasoning on it, and then adapt their behaviors accordingly. With theproliferation of context-aware systems and smart sensors, real-time monitoring of environmental situations (context) has become quite trivial. However,it is often challenging because the imperfect nature of context can cause theinconsistent behavior of the system. In this paper, we propose a contextaware intelligent decision support formalism to assist cognitively impairedpeople in managing their routine life activities. For this, we present a semanticknowledge-based framework to contextualize the information from the environment using the protégé ontology editor and Semantic Web Rule Language(SWRL) rules. The set of contextualized information and the set of rulesacquired from the ontology can be used to model Context-aware Multi-AgentSystems (CMAS) in order to autonomously plan all activities of the users andnotify users to act accordingly. To illustrate the use of the proposed formalism,we model a case study of Mild Cognitive Impaired (MCI) patients usingColored Petri Nets (CPN) to show the reasoning process on how the contextaware agents collaboratively plan activities on the user’s behalf and validatethe correctness properties of the system.

当前,随着社会经济的逐步发展和越来越城市化,在土木建设工程中深基坑支护获得了越来越多的关注,也成为了时下的难点。靠近地铁隧道、地铁站等地下结构的深基坑支护结构,受附近地下建筑物和土体的约束,影响支护结构的支护方式和变形稳定性,导致土压力分布不同本研究在前人研究的基础上,针对地铁隧道双排桩、基坑、基坑支护结构的联合作用,建立了三维有限元模型,采用大型通用计算程序ABAQUS模拟西安施工过程的单元计算模型。研究了有限宽度土深基孔双排桩支护系统的理想设计方法和变形特性,得出以下结论:1、在地铁隧道附近的深基坑工程中,双排桩能有效应对复杂的周边环境,减少基坑周围土体位移,为基坑开挖提供良好的支撑。本文介绍了双排桩支撑系统的参数优化:桩长33米,桩径1.2米,桩刚度,桩间距2D,桩排间距4D。2、双排桩支护结构与单排桩的变形特征不同:单排桩的变形曲线是上大下小的渐变曲线,而双排桩的变形曲线是上下小、中间大的弓形或双反弯点曲线。双排桩支撑体系中桩体的最大位移明显小于单排桩支撑结构。冠梁的存在可以极大地改变双排桩的变形状况,导致桩顶位移显著减小。前后桩会有一个中间大的弓形或双反弯点位移曲线并且两侧细小。3、双排桩支护系统受力或变形情况的变化,可由桩长、直径、刚度、桩间距、桩排间距的变化引起:使基坑周围的土壤更受限制。(1)桩长由27m增加到35m时,桩的最大水平位移降低了 2cm左右,降低幅度为29%。桩长可以改变双排桩支撑结构的变形形式,有效减小桩顶位移和最大位移,有效增加桩的嵌入效果。能有效减小双排桩的水平位移,有利于双排桩支护结构的稳定性。(2)桩径由0.6m增加至1.4m时,桩身最大水平位移降低3cm左右,降低幅度为38%°双排桩的横向抗弯刚度随着桩径的增加而增加,这显著增强了双排桩对基坑周围土体的限制作用。该技术有效地减少了基坑周围的水平土壤位移,同时还增加了双排桩支撑结构的稳定性。(3)当柱刚度从0.5EI增加到1.5EI时,桩的最大水平位移减少了 2.2cm左右,相关减少了 27%。增加桩身刚度,提高桩身对周围土体的抵抗力,从而减小桩身的水平位移,有利于双排桩支护系统的稳定性。(1)国家研究表明,当桩距从2D增加到6D时,后桩的最大水平位移增加了1.99cm,而前桩的最大水平位移增加了 3.3c,上升率分别为52%和75%,前排桩的水平位移增加比后排桩大得多。随着桩间距的增加,相同间距内的双排桩数量会减少,其横向抗弯能力会不知不觉地降低,这对基坑的支护条件是不利的。(2)桩排间距由2D增加到6D时,前后桩最大水平位移分别减少3.32cm和2.65cm,减少幅度分别为50.69%和38.97%。通过增加双排桩的桩排间距,可以调整桩间土壤的分布比例,从而减少桩的水平位移。随着桩排间距的增加,桩的水平位移会继续减小。1、针对双排桩不同弯矩分布特点,采用多种加固方法,降低工程造价:当桩长和单桩弯矩分布不同时,可采用分段加固。当前后排桩的直径和弯矩不同时,可以使用不对称加固。当桩排间距和单桩弯矩增加量不同时,可以同时使用分段配筋和不对称配筋。2、随着基础隧道距离从10米增加到30米,地铁隧道水平位移从5.6米下降到2.1米,相关减少62.9%;垂直位移从3.7米减少到0.7米,减少了 80.7%。由于减小幅度较大,水平和竖向位移均呈下降趋势。基坑开挖对地铁隧道的影响越明显,基坑与隧道的距离越近。地铁隧道的存在会使基坑与隧道距离较小时改变双排桩的力学变形性能,降低基坑与隧道之间的地表沉降,但地表沉降距离基坑末端会不断增加,地铁隧道对基坑有一定的屏蔽作用;当基坑与隧道距离较大时,基坑与隧道之间的地表沉降减小,但地表沉降远离。3、随着基坑开挖深度由15米增加到25米,地铁隧道水平位移由0.7厘米增加到11.6厘米,相差1426.3%;垂直位移由2.5cm增加到10.4cm,相差308.2%。横轴和纵轴位移均呈上升趋势,增长幅度异常大。基坑开挖对地铁管道的影响越大,基坑开挖深度越深。地铁隧道的存在对其紧邻的基坑开挖有重大影响。地铁隧道的存在可以改变基坑与地铁隧道之间的土体沉降方式,以及双排桩支护系统的变形特性。随着基坑开挖深度的增加,地铁隧道对基坑开挖的影响会逐渐减弱,双排桩支护结构的水平位移会明显增加,基坑周围的地表沉降会迅速增加。

Significance of body material and temperature variation on burning time and burning rate of Si/Pb O/Pb_3O_4/FG and B/BaCrO_4/FG pyrotechnic delay compositions were experimentally studied. Brass and stainless steel were used as delay body materials. High resolution oscilloscope and a customized chronometer were simultaneously used for the measurement of burning time and burning rate. Results reveal that brass material with controlled column dimensions reduced the variation in burning time of Si/Pb O/Pb_3O_4/FG delay mixture from 7.43% to 4.17% and that of B/Ba CrO_4/FG mixture from 16.83% to 9.39%.Similarly the variation in burning rate was reduced from 7.57% to 4.12% and from 17% to 9.69% for Si/Pb O/Pb_3O_4/FG and B/BaCrO_4/FG mixtures respectively. Si/PbO/Pb_3O_4/FG delay mixture was also subjected to temperature ranging from -54℃ up to+100℃. The burning rate of this composition varied linearly with temperature. Burning rate increased from 28.01 mm/s to 34.38 mm/s when the temperature was varied from -54℃ to +100℃.
