Title: Adaptive Control for an HVDC Transmission Link with FACTS and a Wind Farm
Authors: Yufei Tang, Haibo He, Senior Member, IEEE, and Jinyu Wen, Member, IEEE
Abstract: Due to the nonlinearity, uncertainty and complex-ity of the power system, it is a challenging task to design aneffective control approach based on the exact model using tradi-tional methods. In this paper, we investigate the application of anovel approximate dynamic programming (ADP) architecture,goal representation heuristic dynamic programming (GrHDP),to a large benchmark power system. Unlike traditional ADPdesign with an action network and a critic network, GrHDPintegrates the third network, a goal network, into the actor-critic design (ACD) to automatically and adaptively build an in-ternal reinforcement signal representation to facilitate learningand optimization. Then the GrHDP is employed to control thebenchmark power system including a DFIG based wind farmand a STATCOM with HVDC transmission. Various powersystem states, including the voltage of STATCOM, current ofDFIG and DC current of HVDC inverter, are provided to theGrHDP controller to generate three adaptive supplementarycontrol signals. These adaptive supplementary control signalsare then provided to the STATCOM controller, DFIG rotor sidecontroller and HVDC master control, respectively. This controlstructure is validated in Matlab/Simulink to demonstrate itseffectiveness in power system control.

Title: Slim Ware: Dynamic Interfacing Method for Lightweight Middleware in Mobile Computing
Authors: TaeGyu Lee, GiSoo Chung
Abstract: we propose the dynamics and mobility interface method for light-weighting of middleware in mobile computing applications. The previous middleware did not properly support the lightweight and mobility of mobile user terminals. Therefore this paper presents the dynamic configuration method of mobile middleware components and the mobility interface strategy. The proposed middleware system called of "SlimWare" provides the component dynamic logic and the interface design.

Title: RFID-based Location System for Forest Search and Rescue Missions
Authors: Soukayna Mouatadid, Zineb Fatara, Yassine SalihAlj
Abstract: This paper presents the framework of an RFID-based rescue robot for missing people in forest environment. The three main design considerations include the reliability, the cost, and the environmental sustainability. For that, the paper analyzes different outdoor location technologies that can be used for this task, namely GPS, WiMAX and RFID. Former research in mobile robots based on GPS and WiMAX has resulted in high costs systems while RFID offers a lower cost alternative. The aim of this work is to provide an already existing mobile robot with RFID technology. Moreover, to overcome the inability of current rescue robots to detect human presence, the addition of an Infrared camera with thermal sensors is discussed. Finally, in order to optimize the energy management and to increase the autonomy of the rescue robot, the paper presents a power supply solution using solar energy.
