The present paper describes the activities carried out at Chieti-Pescara University after the 2009 L'Aquila Earthquake. The activities are multidisciplinary and have involved both engineers (structural and industrial) and architects (urban planner and specialist in historical buildings). The goal was to obtain a comprehensive approach to old towns reconstruction. This activity is particularly important to minimize the earthquake consequences.Two peculiar aspects of the work are selected among other ones and presented within this paper. The first one is: how reliable are speedy in-situ surveys, in order to evaluate post-earthquake damages and building occupancy? Considering that both people safety and reconstruction funding depend on this judgment, it is important to check the procedure reliability. The second aspect is the analysis of an old urban center, viewed as a system of fragile components. System components are both material (e.g. a particular building) and immaterial (e.g. availability of the road system), and have been selected to maximize inhabitants safety, above all in terms of first aid to injured people and in terms of efficiency of strategic structures and infrastructures. These considerations are being slowly introduced in the Seismic Italian Code.

The inverted pendulum system is a challenging control problem in the control theory, which continually moves away from a stable state. The paper presents the design of a Proportional-Integral-Derivative (PID) controller for a single-input multi-output (SIMO) inverted pendulum system and using the Bees Algorithm (BA) to obtain optimal gains for PID controllers. The Bees Algorithm optimizes the gains so that the controller can move the cart to a desired position with the minimum amount of the change in the pendulum’s angle from the vertically upright position during the movement. The tuning aim is to minimize the control responses of the cart’s position and the pendulum’s angle in time domain. MATLAB/Simulink simulation has been performed to demonstrate that the effects on the system performance of PID controllers with optimal gains. The obtained results show that the tuning method by using the Bees Algorithm produced PID controllers successfully within the controller design criteria. Following a description of the inverted pendulum system and the Bees Algorithm, the paper gives the obtained simulation results for the system demonstrating the efficiency of the design.

This paper presents a new approach for designing the Power System Stabilizer. As in power system network, low frequency oscillation always occurs for a long period of time that will decrease the power transfer capability. Power System Stabilizer known as PSS is being installed as one of the control devices in a generating unit. The conventional PSS (CPSS) is the most commonly used in power system, which uses lead-lag compensation. The lack in CPSS has drawn an interest of designing the new approach of PSS to outperform the conventional one. Thus, Bees Algorithm (BA) which is known as one of the numerous intelligent optimization methods is proposed in this paper. It is appears to aid the system stability by optimizing the PSS parameters tuning. The PSS with the BA approach is labelled as BA-PSS and being tested on single machine infinite bus system (SMIB) in Matlab/Simulink environment. BA-PSS performance is compared with CPSS as to validate the ability of the proposed method to achieve great performance in power system stability enhancement. Different type of mechanical input is being injected into the system and the result shows that BA-PSS is capable to optimize the parameters tuning of PSS. BA-PSS also improved the unstable or poorly stable modes as the system achieve the stability with lower overshoot and less time settling. The superior response of BA-PSS controller proved the ability of BA approach in which is capable to solve the lack in CPSS with better performance in enhancing the system stability.

The query of database must rely on professional query language, which is difficult to grasp for ordinary users. Natural language query interface (NLQI) can be applied to solve this problem with better human-computer interaction and intelligence. However, current natural language understanding technology is not mature. Though the query sentences’ structure is fixed, it is also difficult to accurately convert query sentences into understandable database query language for computer. Therefore a method of designing NLQI based on syntax and semantic analysis is proposed in this paper. First of all, Maximum forward and maximum reverse matching algorithms are used to analyse sentence by part of speech (POS) template, which is able to demonstrate the syntax relationship among the words. After syntax analysis, query conditions and targets are identified. Then, single conditions and targets are analyzed to relative standard forms by the relationship among entity, property, connect verb and unit. At last, these standard forms are transformed to SQL sentence. Regarding printing ERP system as experimental subject, experiment is done in this paper. The result shows that the method proposed in this paper can meet the needs of natural language query, and has a good transform effect for combination, omitting and other complex sentences.

Sliding mode control systems provide robust and simple means for controlling linear and nonlinear plants whose parameters may vary within known boundaries. The existence of an ideal sliding mode requires fast switching, which induces chattering in the system, may excite high frequency plant dynamics and consequently affect the stability of the system. This paper proposes a new simple sliding mode controller based on second order reachability law. The reachability condition in this paper is based not only on the first derivative of the switching function but also on its second derivative. The proposed controller alleviates chattering, guarantees zero steady state error, and offers smooth transients for the system states. To demonstrate the validity of the proposed controller, a second order system is used as a workbench example. The simulation results of the workbench example using MATLAB illustrate the feasibility and efficacy of the proposed controller.
