For four representative noises： the Gaussian noise, the uniform noise, the Laplace noise and the Cauchy noise, when the signal is subthreshold, noise can improve the correlation coefficient and SR exists. The efficacy of SR can be significantly enhanced and the maximum of the correlation coefficient can dramatically approach to one as the number of the threshold devices in the parallel array increases. Two theorems are presented to prove that SR has some robustness to noises in the parallel array. These results further extend the applicability of SR in signal processing.展开更多

Her first novel, The Country Girls （1960）, was an immediate success. Her writing is lyrical and intense with passions and aspirations. Set in Britain, the short story Cord describes a story about how the mother and the daughter got along in the short reunion after a long separation. The paper mainly explores different religious values, cultural values, and social values between them which caused irreconcilable conflicts. The present paper concludes that the ＂Cord＂, the blood tie, can never get rid of the spiritual barrier. Only mutual understanding can eliminate the gap and acquire a harmonious relation between parents and children.展开更多

Thee article illustrated that the new views of nature and environment are the important philosophical foundation of project ethics from three aspects： the recognition of the relationship between man and nature, the meditation of traditional mode of production, and the ecological and environmental consciousness.展开更多
