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.

Title: Energy Efficient Video Decoding for the Android Operating System
Authors: WenYew Liang, MingFeng Chang, YenLin Chen and ChinFeng Lai
Abstract: Dynamic voltage and frequency scaling (DVFS) is an effective technique for reducing power consumption. Due to the increasing popularity of multimedia applications for portable consumer electronic devices, the importance on reducing their power consumption becomes significant. This paper proposed a table-based DVFS mechanism for frame decoding that reduces the power consumption of a processor by exploiting the frame decoding complexity. A table-based DVFS predictor is used in the frame decoding prediction. This study was implemented in the Android operating system on an Intel PXA27x embedded platform. Experiment results showed that the energy consumption of decoding videos can be reduced from 9% to 17%, whereas the frame drop-rate is less than 3%.

Title: Indoor Air Quality Control for Energy-Efficient Buildings Using CO 2 Predictive Model
Authors: Zhu Wang and Lingfeng Wang
Abstract: In this paper, an intelligent control system for indoor air quality in energy-efficient buildings is proposed. The goal of intelligent air quality control for energy-efficient buildings is to maintain the indoor CO 2 concentration in the comfort zone with a minimum amount of energy consumption. In this study, the CO 2 concentration is used as the indicator of indoor air quality and a CO 2 predictive model is utilized to forecast the indoor CO2 concentration. Particle swarm optimization (PSO) is applied to derive the optimal ventilation rate. As compared with the traditional ON/OFF ventilation control system, the performance of the proposed intelligent control system has demonstrated its advantage in terms of energy savings. A case study and corresponding simulation results are detailed in the paper.
