Finite Element Preconditioning on Spectral Element Discretizations for Coupled Elliptic Equations by JongKyum Kwon, Soorok Ryu, Philsu Kim, Sang Dong Kim

“…The uniform bounds on eigenvalues of B^h2−1A^N2 are shown both analytically and numerically by the P1 finite element preconditioner B^h2−1 for the Legendre spectral element system A^N2u¯=f¯ which is arisen from a coupled elliptic system occurred by an optimal control problem. The finite element preconditioner is corresponding to a leading part of the coupled elliptic system.…”

Application oriented cross-layer multi-channel MAC protocol for VANET by Cai-xia SONG, Guo-zhen TAN, Nan DING, Jun-ling BU, Fu-xin ZHANG, Ming-jian LIU

“…An application oriented cross-layer multi-channel(AOCM)MAC protocol was proposed for VANET.The AOCM protocol could derive the optimal control channel(CCH)interval to ensure the timely and reliable transmission of safety messages on the CCH,based on real-time statistics and prediction for different types of sages coming from upper application layer.In the service channels(SCH),the proposed protocol relies on a reservation mechanism for con-tention-free transmission,so as to improve the throughput of SCH.The proposed protocol was suitable for both saturation and unsaturation conditions,and has low computational complexity and high scalability.Extensive simulation results demonstrate the superiority of the AOCM protocol compared with other existing protocols.…”

Design and analysis of active queue management algorithm based on predictive control by WANG Ping, CHEN Hong, LU Xiao-hui

“…Model predictive control as a novel active queue management（AQM） algorithm was proposed for Internet system with large delay,called MPAQM.Considering the causality of time-delay system,the predicted output was defined.Then,the control requirement was converted to the optimal control objective,and the drop probability was obtained by solving the optimal problem.Furthermore,the delay-independent stability condition of closed-loop system was derived,which gave the guidelines how to select the parameters of MPAQM algorithm to assure the stability and fast convergence of the network system.The performances of MPAQM were evaluated through a series of simulations in NS2 under the single/multiple topology.The simulation results show that the queue length with MPAQM algorithm reaches the desired value with minimal tracking error and lower drop probability.MPAQM algorithm outperforms RED,PI and SPI-RED algorithms in terms of disturbance rejection,stability,and robustness.…”
