Ancient Ecological Security Con-sciousness in City Site Selection

【中文文摘】我国古代城市选址的安全因素包含着两层涵义:自然环境(生态)安全因素和军事安全因素。城市选址的生态安全,一般要从饮用水源、区位及交通条件、气候和抵御自然灾害的能力、发展前景乃至阴阳八卦等方面综合考虑。城市发展水平最终取决于城市所在位置与区域的自然生态演化进程与走向。 【英文文摘】The ancient ecological consciousness incity site selection is inclusive of the meanings intwo aspects:natural environment(eco-environment)security factor and military security factor.Generally,the overall considerations should be made,whileselecting the city sites,on the drinking water source,geographical location and transport conditions,cli-mate and the anti-disaster capacity,developmentprospect and, even on the Yin-Yang Eight Diagrams.The development level of a city is finally determinedby the city location and the natural ecology evolvement and its trend in the region.国家自然科学基金项目(50125820)部分成

多言語コーパスと日本語研究 : 「中日対訳コーパス」の利用研究例から

北京日本学研究センターBeijing Center for Japanese Studies多言語コーパスに焦点を絞って,まずこれまで多言語コーパスを分類するための基準が不足していたことを指摘する。さらに,多言語コーパスというものにおいては異なる言語がさまざまな関係によって関連付けられていることを示し,その関係を分類するための基準を提案する。その上で,多言語コーパスをどのように選定し,使い分けるべきかについての目安を示す。また,「中日対訳コーパス」の作成と利用経験を踏まえて,訳文データの特性に気付かず原語と対等に使うなどの利用上の問題点を指摘したうえ,筆者が提示した利用モデルを説明し,「可能だ」という可能表現,終助詞「だろう」の意味用法,日中同形語である「基本」の意味用法などに関する日中対照研究の事例を通して,対訳コーパスを適正に利用する方法とその効果を示す。Recent developments of the computer-readable corpus and their applications have become increasingly diversified, and the type of users has also expanded to a wider community. These changes have created new problems in application, and studies on these problems have attracted much attention. The problems include ascertaining the characteristics, potentiality, and limitation of each corpus, and complying with the user\u27s specific requirements. Based on the series of research results from building and using the Japanese-Chinese parallel corpora for Japanese studies, the author points out the importance of fully understanding the characteristics of each corpus and the problems of treating sentences in parallel corpora as the equivalent of the original sentences. As an illustration of these issues and to demonstrate the best of use of parallel corpus, he presents his study using particular examples, including the Japanese expression kanou-da denoting the possibility, the sentence final particle daroo, and kihon (jiben) that has the same form in Japanese and Chinese

Jointing sparse recovery estimation algorithm of underwater acoustic channels with long time delay spread

对具有长时延扩展的水声信道,传统的信道估计算法如最小二乘法将在大量零值抽头产生严重的估计噪声,导致估计性能下降,同时信道估计时所需的较高估计器阶数大大提高了运算复杂度。压缩感知信道估计方法可有效利用多径稀疏特性改善性能,但需采用较大的训练序列长度以保证稀疏恢复精度,由此导致额外的系统开销。利用水声信道多径稀疏结构在数据块间存在的相关性,建立基于分布式压缩感知的长时延水声信道联合稀疏模型,从而可利用同步正交匹配追踪算法进行联合重构,以进一步减小系统的训练序列开销,提高估计性能。最后通过仿真和海上实验验证了所提方法的有效性。Efficient estimation of underwater acoustic channels with a large time delay spread was addressed. For the conventional channel estimation methods such as LS, this type of channel estimation would produce serious estimation noise in zero-value taps which lead to poor performance of channel estimation. At the same time, a large time delay spread posed significant difficulties such as large channel order and the corresponding huge computation complexity. Compressed sensing(CS) channel estimation algorithm offered a solution to this problem by exploiting the sparsity of channel to improve the estimation performance. However, to ensure acceptable estimation performance, a long training sequence was needed, which unfortunately would cause additional overhead. A method was proposed which exploiting the joint correlation of sparse multipath structure between adjacent data blocks to deal with the estimation of long time delay channels under the framework of distributed compressed sensing(DCS).Thus the large time delay underwater acoustic channels can be jointly reconstructed by the simultaneous orthogonal matching pursuit(SOMP) algorithm to facilitate the system overhead reduction and estimation performance improvement. Simulation as well as the sea trial results indicate the effectiveness of the proposed method.国家自然科学基金资助项目(No.11274259,No.11574258)~

Acoustic inspection of wall hollowing based on SPCE61A single-chip microcomputer

针对建筑外墙空鼓的检测要求,利用振动与声学理论进行敲击过程的建模和敲击声学特性分析,在此基础上设计了一个基于16位凌阳单片机SPCE61A的嵌入式墙体无损检测系统。由于SPCE61A片内资源有限,通过片内资源的高效调配设计及算法优化实现多点数快速傅立叶计算,提高系统检测性能。实验数据表现的敲击声中低频段能量比与墙体结构的关系与理论分析基本吻合。门限检测方法对墙体进行识别,取100个好墙体的敲击声在9kHz处平均能量的0.6倍作为门限进行检测。实测200次敲击,正确识别率高达99%。如果环境噪声较大,而仍利用门限检测方法,则正确率识别率下降较大。实验结果表明了该系统的有效性。To tackle the safety threats caused by the wall hollowing,this paper designs an acoustic no-ndestructive inspection system based on embedded Sunplus SPCE61A single-chip microcomputer. The imp-act process and the resulting sound emission are analyzed theoretically to obtain the relationship between the hollow wall and the corresponding acoustic feature. Due to the limited on-chip memory capacity of the SPCE61A,the present system adopts the memory distribution and Fast Fourier Transform (FFT) algorithm optimization to realize 256-point FFT computation to ensure the detection performance. Experimental res-ults demonstrate the effectiveness of the present system,which has the potential of being developed as a portable,convenient,accurate and low-cost inspection tool.福建省科技计划重点项目(No.2007H0030);; 香港特区政府RGC项目(No.CityU 1166/02E)资助
