Temporal variation in modal properties of a base-isolated building during an earthquake

Temporal variation of dynamical modal properties of a base-isolated building is investigated using earthquake records in the building. A batch processing least-squares estimation method is applied to segment-wise time-series data. To construct an input-output system, an auto-regressive model with exogenous input （ARX） of second-order including a forgetting coefficient as a weighting coefficient is used for the estimation of modal parameters. The fundamental and second natural frequencies and the damping ratios of the fundamental and second natural modes of the base-isolated building are identified in the time domain. The identified results are consistent with the results obtained from the micro-tremor vibration data, forced-vibration test data and earthquake records in the present base-isolated building in the case of taking into account the amplitude-dependency of the iso- lators and viscous dampers. It is finally pointed out that several factors, e.g., amplitude dependency of the isolator and damper system and special characteristics of the series-type viscous damper system, may be related complicatedly with the temporal variation in modal properties of the above-mentioned system.     

输入输出理论——任务型教学与大学英语视听说课教学模式的创新

学习者不仅需要可理解性输入,更需要可理解性输出,从而使其二语既流利又准确.任务型语言教学是将真实的语言材料带入课堂,印在虚拟的环境下进行真实的语言练习.这与我们所倡导的重视语言输出,提高学生的口语水平,能有效的使用英语进行交际相一致.在语言输入输出理论指导下的任务型教学充分调动了学生学习英语的积极性,发挥了学生的主体作用和老师的引导作用,提高了学生的英语水平,同时通过任务的完成培养了学生的自主学习能力.     

大学英语课程2+2+1教学模式研究

大学英语教学模式要满足国家和社会对人才培养的需要,采用多媒体大班授课,网络自主学习和口语练习是有效的互补式的大学英语的教学模式,有利于培养提高学生英语综合应用能力。     

Input-output approach to robust stability and stabilization for uncertain singular systems with time-varying discrete and distributed delays

Based on input-output approach, the robust stability and stabilization problems for uncertain singular systemswith time-varying delays are investigated. The parameter uncertainties are assumed to be norm-bounded and the time-varying delays include both discrete delay and distributed delay. By introducing a new input-output model, the time-delay system is embedded in a family of systems with a forward system without time delay and a dynamical feedback uncertainty. A sufficient and necessary condition, which guarantees the system regular, impulse-free and stable for all admissible uncertainties, is obtained. Based on the strict linear matrix inequality, the desired robust state feedback controller is also obtained. Finally, a numerical example is provided to demonstrate the application of the proposed method.
