作者： Wen H. Chen (Compression Labs, Inc. 2860 Junction Ave SanJose ,ca 95134)

Video is used across a range of applicaticos,from low data-rate mdeo telephony to digitalbroadcast high deftnuzontelevision. Since all applications in thts range require that digually represent-ed sequece of images be reduced in let-rtue for efficient transmision or strage, all applications can uli-lize the same core compression technology. CLI has spent nearl two decades advancing the quality andapplication of digitof video technolegy and continues to rvaluaie meny video compression techniques in-cluding fractof coding, mavelets, subband coding, the discreie cisine transform (DCT), and vectorquantization. CLI currently has concluded that the discrete cosine transform (DCT) combined with mo-tion compensation provides the best pictrue quality for a wide range of video applicarions. In face, theDCT is the technology used by telecommunicationscomputer, and consumer video standards such as H.261 ,JPEG ,adn MPEG. This paper reviews these and other digital video compression iechnologies andthen discusses how CLI applies them to dtfferent video applications. Even within standardsbased mar-kets such as that for MPEG video ditribution syuerns, different products are differentiated easily bydifferences between their proprietary methods for preprocessing ,coding mode selection, postprocessing,etc.

新闻报道的空间建构是新闻报道有效叙事之重点环节,聚焦于现场的报道,是一种立足于深刻认知新闻现场和现场新闻之内在关联的选择性重构,现场既代表新闻报道的语境与情境还原,同时也是实现传受双方互动理解的一种审美超越。现场的报道空... 详细信息

新闻报道的空间建构是新闻报道有效叙事之重点环节,聚焦于现场的报道,是一种立足于深刻认知新闻现场和现场新闻之内在关联的选择性重构,现场既代表新闻报道的语境与情境还原,同时也是实现传受双方互动理解的一种审美超越。现场的报道空间建构不仅体现出新闻报道的时效要求对叙事策略选择的必然,更通过叙事设计的结构化、进入化策略来实践传受双方知觉场的共建,尤其在当代新媒体环境下,新闻报道的空间叙事策略将伴随社会空间的心灵感知而不断创新发展。重视并有效发掘、应用那些能够激发受众感知的想象力的空间要素,才是新闻报道未来创新的方向,空间的重构也绝非是媒介技术提供的拟态逼真,而是构建合乎受众认知需求与审美体验的空间实践,是叙事的社会参与,也是其心灵对话空间的共建。

作为语言类型学建立的一种新型语义分析工具,语义地图是描写和解释多功能语素关联类型的一种有效方法。本文试图从语义地图理论的视角,建立汉语方位介词“在”与韩语、日语中相应表达形式,以及与英语、西班牙语中相应表达形式的语义地图模型,并通过对语义地图的对比,考察这一工具是否与偏误研究的结论一致,是否有助于挖掘不同母语背景的留学生对汉语介词的习得特征,以及是否能为对外汉语介词教学提供有效的针对性教学方针和策略。

Acta Mathematica Scientia 2011年第6期31卷 2247-2264页

Using an improved computational fluid dynamics （CFD） method developed for highly unsteady three-dimensional flows, numerical simulations for oscillating flow cycles and detailed unsteady simulations of the flow and forces on the aortic vessels at the iliac bifurcation, for both healthy and diseased patients, are analyzed. Improvements in computational efficiency and acceleration in convergence are achieved by calculating both an unsteady pressure gradient which is due to fluid acceleration and a good global pressure field correction based on mass flow for the pressure Poisson equation. Applications of the enhanced method to oscillatory flow in curved pipes yield an order of magnitude increase in speed and efficiency, thus allowing the study of more complex flow problems such as flow through the mammalian abdominal aorta at the iliac arteries bifurcation. To analyze the large forces which can exist on stent graft of patients with abdominal aor- tic aneurysm （AAA） disease, a complete derivation of the force equations is presented. The accelerated numerical algorithm and the force equations derived are used to calculate flow and forces for two individuals whose geometry is obtained from CT data and whose respective blood pressure measurements are obtained experimentally. Although the use of endovascular stent grafts in diseased patients can alter vessel geometries, the physical characteristics of stents are still very different when compared to native blood vessels of healthy subjects. The geometry for the AAA stent graph patient studied in this investigation induced flows that resulted in large forces that are primarily caused by the blood pressure. These forces are also directly related to the flow cross-sectional area and the angle of the iliac arteries relative to the main descending aorta. Furthermore, the fluid flow is significantly disturbed in the diseased patient with large flow recirculation and stagnant regions which are not present for healthy subjects.
