A Staged Finite-Time Control Strategy for Formation of Underactuated Unmanned Surface Vehicles by Hui Ye, Xiaofei Yang, Chunxiao Ge, Zhaoping Du

“…The formation control issue for a group of underactuated unmanned surface vehicles (USVs) is discussed in the paper, and a staged finite-time control strategy for the USVs is proposed. Firstly, we try to steer each USV to its own starting point in the formation for a limited time, under the initial condition that each of these vehicles is parked at random. …”

Knee Point Search Using Cascading Top-k Sorting with Minimized Time Complexity by Zheng Wang, Shian-Shyong Tseng

“…And in each step an optimization problem of the selection number k is solved, where the objective function is defined as the expected time cost. Because the expected time cost in one step is dependent on that of the afterwards steps, we simplify the optimization problem by minimizing the maximum expected time cost. …”

Nash equilibria – existence, uniqueness and convergence – in two person non-zero games of timing by Daina Sūdžiūtė

“… Special class of Nash equilibria with spectra S1 = S2 = {a,b} is investigated in two person non-zero games of timing. The formulas of the existing and unique equilibria are derived when the kernels satisfy some conditions of monotonicity and boundedness. …”

Low-Complexity Decoding Algorithms for Distributed Space-Time Coded Regenerative Relay Systems by Chao Zhang, Huarui Yin

“…We examine decoding structure for distributed space-time coded regenerative relay networks. Given the possible demodulation error at the regenerative relays, we provide a general framework of error aware decoder, where the receiver exploits the demodulation error probability of relays to improve the system performance. …”
