广西高水头水电站的规划与实践

广西高水头水电站的规划建设从1958年开始,首先建成的是玉林市大容山水电站,设计水头224 m,初期装机6 480 kW,后增加引水流量,扩机至11 160 kW,至今运行良好;20世纪90年代以来高水头电站的规划、建设进入了一个高潮,以天湖水电站一期为代表,设计水头1 074 m,装机30 000 kW,年发电量9 610万kW*h,于1992年建成投产,运行良好.据不完全统计,至2001年底广西已建成水头200 m以上的水电站80座,装机25.8万kW,年发电量11.8亿kW*h,为广西农村电气化建设,生态环境保护、社会可持续发展做出了重大贡献.     

Cognitive science: Making the whole different from the sum of its parts.

Reviews the book, From models to modules: Studies in cognitive science from the McGill workshops edited by I. Gopnik and M. Gopnik (1986). This book is only moderately successful in conveying the exciting advances that are beginning to appear as a result of the interdisciplinary efforts in cognitive science. The book's emphasis on language processes and linguistics will seriously limit its potential readership, although there are some contributions from outside that domain. Moreover, many of the chapters were not prepared with a general audience in mind, and to appreciate a number of the chapters fully the reader must have a strong linguistic background. A more severe problem is that the chapters are based on a series of workshops held at McGill University in 1982 and 1983. The sad consequences are that (a) the book is badly out of date (few references are more recent than 1983), (b) most of the contributions were not original but were based on ideas and results that were or were about to be in print at the time the workshops were held, and (c) many of the chapters are so short that they do not provide adequate depth of coverage. At this late date, the value of the book may be as a summary of a few of the early issues and methodologies that have captured the attention of cognitive scientists.

Integrative Cognitive Therapy for Depression: A Preliminary Investigation.

This study is a preliminary investigation of an integrative treatment aimed at improving the efficacy of cognitive therapy (CT) for depression. The development of the treatment protocol was based on process findings, which suggested that strategies used in CT to resolve alliance ruptures may actually exacerbate problems in the therapeutic relationship. The protocol integrates, within the traditional CT treatment manual, procedures to repair alliance ruptures that are derived from or consistent with humanistic and interpersonal therapies. Although conducted by inexperienced therapists, the integrative treatment led to greater improvement than a waiting-list condition. The results also compare favorably to previous findings for CT.

The Structure of Working Memory From 4 to 15 Years of Age.

The structure of working memory and its development across the childhood years were investigated in children 4-15 years of age. The children were given multiple assessments of each component of the A. D. Baddeley and G. Hitch (1974) working memory model. Broadly similar linear functions characterized performance on all measures as a function of age. From 6 years onward, a model consisting of 3 distinct but correlated factors corresponding to the working memory model provided a good fit to the data. The results indicate that the basic modular structure of working memory is present from 6 years of age and possibly earlier, with each component undergoing sizable expansion in functional capacity throughout the early and middle school years to adolescence.

防御超强台风的实践与思考

超强台风具有巨大的破坏力,如何防御超强台风并降低其灾害损失是一重大课题。浙江省在防御“桑美”超强台风的实践中认为,要取得防台抗灾的胜利,未雨绸缪、常备不懈是基础,以人为本、有效避险是关键。同时,针对“桑美”登陆后暴露出的各种问题,今后还要从4个方面加强工作,即建立集中与分散相结合的避险体系;加强电力、通信等应急基础保障能力建设;全面建成监测预警体系;加强超强台风研究,进一步完善防台风预案。     

A Review of Wavelets for Digital Wireless Communication

Wavelets have been favorably applied in almost all aspects of digital wireless communication systems including data compression, source and channel coding, signal denoising, channel modeling and design of transceivers. The main property of wavelets in these applications is in their flexibility and ability to characterize signals accurately. In this paper recent trends and developments in the use of wavelets in wireless communications are reviewed. Major applications of wavelets in wireless channel modeling, interference mitigation, denoising, OFDM modulation, multiple access, Ultra Wideband communications, cognitive radio and wireless networks are surveyed. The confluence of information and communication technologies and the possibility of ubiquitous connectivity have posed a challenge to developing technologies and architectures capable of handling large volumes of data under severe resource constraints such as power and bandwidth. Wavelets are uniquely qualified to address this challenge. The flexibility and adaptation provided by wavelets have made wavelet technology a strong candidate for future wireless communication.
