预应力混凝土连续梁桥合龙顺序对结构内力的影响分析

分析了三跨一联连续梁桥悬臂施工不同合龙顺序可能导致主梁与支座间存在＂间隙＂的缺陷,用MIDAS/Civil程序分别计算了在不同合龙工序状态下,结构内力和变形的变化值。结合实例,模拟计算了当主梁与支座间分别存在1～5 mm间隙时,对主梁内力的影响。理论计算表明,当主梁与支座间存在较小间隙时（3 mm以下）,采用适当的合龙工序,在具有季节性施工的地区,更具有工程实用价值。     

面向多智能体的出行前信息下通勤者出行行为研究

采用面向多智能体的建模与仿真方法,对先进的交通信息系统(ATIS)提供的出行前信息下通勤者出行行为进行了研究.首先,基于贝叶斯理论,建立了在出行前信息与以往出行经验作用下,通勤者出行时间感知动态更新模型;进而以信念-愿望-意图(BDI)模型为基础,将每个通勤者一车辆单元刻画为一个具有双层结构的智能体,并采用面向多智能体语言AgentSpeak(L)刻画了智能体的出行行为决策机制;最后,采用面向多智能体编程平台Jason与微观交通仿真平台Paramics相结合的方式进行了相应的仿真试验.结果表明:贝叶斯理论可以较好地解释驾驶员(尤其是通勤者)出行行为动态特性,同时验证了多智能体技术与微观交通仿真技术的结合在驾驶员行为分析中应用的有效性,为驾驶员行为分析提供了新思路.

Remaining Useful Life Prediction of Turbofan Engine Using Hybrid Model Based on Autoencoder and Bidirectional Long Short-Term Memory

High voltage electrostatics and corona discharge are utilized for various applications in pollution and environmental control. The traditional applications have many flaws due to improper construction of electrode design and assembly that cause system failure, in particular when electrically stimulated devices are exposed to high humidity. A new innovative-patented design by Hamade, electrically stimulated catalytic converter (ESCC), eliminates such flaws and shows the wide practical applications of the new design. The new design utilized previous patented designs and work of the same inventor but retrofitted for catalytic auto exhaust emission control. The current and previous patents include: employing electrically stimulated filtration (ESF) to replace high efficiency particulate air (HEPA) filters, treatment of biological and infectious diseases, electret fabrication, and, most notably, the invention of a new electrically stimulated catalytic converter (ESCC). The electrically stimulated catalytic converter invention includes an exhaust conduit fed from the engine exhaust port with a housed corona charger apparatus. The opposite end is opened to the atmosphere outside of the vehicle or connected to a reduced-size catalytic converter. The corona charger is intrusively or non-intrusively associated with a main flow path defined by the exhaust conduit. The corona charger includes at least one electrode, which may be recessed away from, the main flow path. A plurality of corona chargers may be used in various combinations, optimally a two dimensional grid. The electrically stimulated catalytic converter is adapted to treat and eliminate auto exhaust pollution emission to air.     

Theoretical,Simulation and Experimental Analysis of Microfluidic Droplet Generation and Recovering Process with Applications in Frying Oil Assessments

The research on microfluidic droplet size prediction has been extensive and fruitful, while the droplet deforming process has been seldom studied. In this paper, a frying-oil-assessing microfluidic device was designed to study the droplet deforming and recovering processes, which were dominated by channel geometry, flow rates, sheath flow viscosity and interfacial tension of the two phases. Theoretical expressions of the deforming process and its extreme value were obtained for the first time, supported by simulation and experiments. Theoretical, simulation and experimental results indicated that the steady-state droplet length could be a useful parameter for frying oil assessment.     

综合施策缓解上海市居住区停车矛盾

面对居住区停车供需矛盾日益突出,上海市近年修订、出台了一系列相关标准和指导意见,在停车规划、建设及管理方面进行探索。首先分析上海市中心城老旧小区停车难的主要原因,即小客车快速增长、停车历史配建不足、车辆随意停放且小区内部空间有限。为缓解居住区停车矛盾,上海市坚持区域差别化发展理念、动态调整居住区停车配建标准,在加强停车配建审核管理、鼓励小区内部挖潜扩容、推进停车错时共享、利用互联网+探索共享新模式、完善夜间道路临时停车管理机制等方面进行了积极的探索和实践。
