Optimal rank reduction

This paper proposes a clustering-based objective reduction method (COR) for MaOPs. The proposed method is more efficient than existing ones and it can automatically determine these parameters. Moreover, the proposed method still achieves comparable results with existing methods.

This paper proposes a novel Large-scale (massive) Multi-input Multi-output Multicarrier Code division multiple access (LS MIMO MC-CDMA) model and application to the Fifth-Generation Mobile Communication Systems (5G). This system uses combined cylindrical array antenna multiple beamforming architecture with spatial multiplexing. The model is optimized by Min-Max criteria in order to minimize side lobes and maximize the reduction of propagation loss. The Monte Carlo simulation results unify with the analytical solution for system performance.

Linear Context-Free Rewriting Systems (LCFRSs) are a grammar formalism capable of modeling discontinuous phrases. Many parsing applications use LCFRSs where the fan-out (a measure of the discontinuity of phrases) does not exceed 2. We present an efficient algorithm for optimal reduction of the length of production right-hand side in LCFRSs with fan-out at most 2. This results in asymptotical running time improvement for known parsing algorithms for this class.
