提出一种三层前馈输入延迟神经网络模型用于建立射频功率放大器有记忆的非线性行为模型.反向传播算法用来训练神经网络以提取神经网络模型参数.在仿真中,提出的模型可以通过典型的偶次多项式有记忆功率放大器模型来证明,并且比较了不同数目的延迟单元和隐层神经感知器的模型结构下的性能.为了用实验验证模型的有效性,建立了能达到60×106 sample/s采样率数字测试平台用于采集功率放大器的输入和输出数据.选用矢量信号源产生的3.75 MHz 16-QAM信号作为功放输入信号来测试功放的动态AM/AM和AM/PM特性.通过分析比较时域和频域仿真结果和实验测试结果,模型在收敛性、精度和执行效率方面都达到很好的效果. 相似文献

以大学生为研究对象,采用《父母教养方式评价量表》(EMBU)和《简易应对方式问卷》(SCSQ)对436名大学生进行问卷调查,探讨其父母教养方式与简易应对法方式的关系。结果表明,大学生体验到更多的父母情感温暖、理解,大学生父母教养方式的多数因子与简易应对方式密切相关。父亲情感温暖、理解和父亲惩罚、严厉对大学生积极应对方式具有显著的影响;父亲拒绝、否认,父亲偏爱被试和父亲过度保护对大学生消极应对有显著的影响。而母亲教养方式对大学生简易应对方式均无显著的影响。 相似文献

对"生活世界"的关注必须具体落实到对生活在世界中的人的"生活方式"的关照,才能彰显"生活世界"之所以存在并超越现状的魅力."生活方式"是生活在"生活世界"中的人的生存形式和内容,是对"生活世界"话语的关注性超越.可以把学生在一定空间中展现出的流动的"生活方式"分为认知方式、理解方式、体验方式、行为方式、话语方式和交往方式,从而在对学生独特的"生活方式"加以考察的基础上要求教育回归学生的"生活方式".如果说"回归"是从教育不注重学生的生活现实出发走向学生的本真存在,那么"超越"不但是对教育"回归"本身的超越、学生本真存在的超越,更是一代新人对成人所代表的现世的超越、是基于回归学生的"生活方式"从而在达成成人和学生的"视界融合"的同时对人类生活的超越. 相似文献

《Adolescence education newsletter》1999,2(2):2
The UN Educational, Scientific and Cultural Organization Regional Clearing House on Population Education has commissioned a series of case studies on the promotion of adolescent reproductive and sexual health, with emphasis placed on advocacy and information, education and communication (IEC). The case studies will document the experiences of Bangladesh, China, India, Indonesia, Iran, Malaysia, Philippines, Sri Lanka, and Thailand. The advocacy activities include programs to gain the support of lawmakers and policymakers, the mass media and other influential groups. IEC activities, on the other hand, reach out to the youth, counselors, teachers and trainers, extension workers and motivators, and health personnel. Advocacy and IEC also differ in strategies. Political lobbying, high level meetings, seminars, mass media campaigns, and advocacy skills training are typical advocacy strategies; while, individual counseling, research, non-governmental organization involvement in communities, youth camps are of IEC strategies. The case studies also examine national policies, program responses and strategies, and factors that have contributed to best practices, and innovative approaches to advocacy and IEC. The impact of the target groups of the case studies will be evaluated and those with successful outcomes will be identified. 相似文献

随着高校后勤化的推进,学生宿舍已经不仅仅是学生睡觉、休息的地方,它更成为学生学习、生活、娱乐、交往的重要场所,也是大学生思想品德、组织纪律、集体主义、精神文明建设、素质教育等诸方面培养和形成的重要阵地,它对学生的人格塑造、道德养成、人生观、世界观、价值观的树立和形成,甚至生活道路的选择,都产生着直接或间接的影响,同时学生宿舍也成为学生违纪的高发地。为了更好的发挥学生宿舍中管理育人、服务育人的功能,高等院校必须更新观念、加大投入,培养一支高素质的管理干部队伍,将大学生宿舍文化建设纳入校园文化建设之中,创建和谐宿舍文化。 相似文献

汉水流域丧歌作为一个典型的汉水文化事象,其中蕴涵着丰富而典范的孝文化、乐感文化和伦理习俗文化等中国文化的核心内核。迎来送往、养生送死、慎终追远、追根溯源等传统道德标准是汉水流域丧歌创作和流传的最深刻文化动因,而其巨大的习俗传承价值、伦理教育价值、历史认识价值、社会心理价值和美学认同价值则是其长期而广泛流传的最直接的现实动因。演唱丧歌是汉水文化习俗的最重要的组成部分和最普遍的表现形式,几乎伴随着汉水流域民俗大礼———丧礼形式的每一过程。加之汉水文化产生和繁育在世界文化遗产与中国道教圣地武当山、世界民间故事村武家沟村、汉民族第一部神话史诗《黑暗传》、第一个以“汉”命名并将“汉”字几乎覆盖所有中国文化事象的朝代汉代和汉民族民歌村吕家河村等古老文化化石和文化富集区所在地,在中国文化产生和演变的历程中具有典范和代表意义,因而,挖掘、整理、保护好汉水流域丧歌,并进而认识、利用、传承好汉水流域丧歌,不仅对于抢救、挖掘、整理、保护、传承、利用地方文化具有示范作用,同时,对于在全球化背景下重新辨证深入地全面认识和实现中国传统文化的价值,实现中国传统文化的科学持续发展,有效地服务于中国特色的精神文明和和谐社会的建设,不仅具有深远的历史文化价值,而且更具有直接强大的现实社会价值。 相似文献
