In this paper, a novel algorithm is presented for the design of sparse linear-phase FIR filters. Compared to traditional l1-optimization-based methods, the proposed algorithm minimizes l1 norm of a portion (instead of all) of nonzero coefficients. In this way, some nonzero coefficients at crucial positions are not affected by l1 norm utilized in the objective function. The proposed algorithm employs...
Evaluation of construction or renovation projects is necessary for the developing of distribution network. A comprehensive evaluation can contribute to find problems in the process of projects and promote scientific level of decision making for future construction or renovation. In this paper, we propose a post evaluation for distribution network. Firstly, we put forward an integrated index system...
This paper attempts to use the GARCH model with macro information based on the VaR method to measure foreign exchange risk. We investigate the impact towards foreign exchange market of the macroeconomic information, and finds the released information of Sino-American monetary and retail trade has the biggest influence on foreign exchange market.
