第四届海峡两岸计算流体力学学术研讨会

作者： Pong-Jeu LU and Ting-Ting JUAN Department of Aeronautics and Astronautics, National Cheng Kung University University Rd., 70101, tainan, Taiwan

＜正＞ A new prosthetic valve design concept is proposed which fully utilizes the aeronautic wing design guidelines. The design objective of this aero-shaped valve （ASV） lies in lowering the valve-induced damage to the blood cells and minimizing the impact momentum between the occluder and the strut of the valve. Based on the theory of wing sections and the analogy of flight stability, an optimization procedure, which integrates Computational Fluid Dynamics （CFD）, Artificial Neural Network （ANN）, and Genetic Algorithm （GA） is developed to search for an optimal occluder shape and a minimal-moment rotating center. Comparing the optimal ASV-1 design to the baseline plate occluder, ASV-1 has better hemodynamic characteristics of lower pressure loss and Reynolds stresses. Moreover, ASV-1 has a nearly zero-moment when reaching the maximum opening angle, resulting in an extremely low impact force. The concern of strut failure and valve sound can thus be greatly relieved. The present work demonstrates that an optimization procedure can help improve the prosthetic valve performance to an extent that cannot be enjoyed by simple intuitive design methods.

第二届仪器科学与技术国际学术研讨会

作者： Terry. Y. Chen and Y. C. Chou Department of Mechanical Engineering National Cheng Kung University tainan Taiwan 701 China

＜正＞ A novel approach, called min-max scan, is proposed to measure the full-field principal stress directions digitally. By using a light-field plan-polariscope and a PC-based image processing system, the intensities of the model images under varying loads are scanned and compared in real-time to form images representing the minimum （isoclinics） and maximum intensities at each point on the model. The influence of isochromatics on the isoclinics is eliminated. Using two sets of images obtained at the angle of 0 and π/8, respectively, the full-field principal stress directions can be determined in the range [0, π/2 ]. Relevant theory for the proposed approach is introduced and the experiment results are shown.

对小分子给体进行氟代,往往能够通过拉深其最高占据分子轨道(HOMO)能级来提高光伏器件的开路电压,从而有助于获得更高的光电转化效率。本工作设计合成了含3′,4′-二氟-3,3″-二辛基三联噻吩结构的新型共轭单元,并通过Stille偶联、Knoevenegal缩合等反应进一步合成了以噻吩取代侧链的苯并二噻吩为核心、氟代三联噻吩为共轭桥、罗丹宁为封端基团的新型小分子电子给体光伏材料(命名为BDT4F-RO)。此分子的结构和初步的理化性能分别通过核磁共振波谱(^(1)H NMR、^(13)C NMR、^(19)F NMR)、紫外-可见吸收光谱、循环伏安法和热重分析等进行测试表征。结果表明:薄膜状态下的BDT4F-RO在300~700 nm均有较强的吸收,吸收边界位于690 nm。与不含氟原子的类似物BDT-RO相比,BDT4F-RO具有较深的HOMO能级,这也使得对应的光伏器件有更高的开路电压(0.95 V)。但是总体的效率上BDT4F-RO远逊于BDT-RO,这可能是氟原子的引入使得BDT4F-RO与受体分子IDIC的混溶性较差所致。

INTRODUCTION Silicon has already been demonstrated as a viable material for passive and active optoelectronic device applications in the infrared regime (λ > 1.2 μm) of the electromagnetic spectrum. Over these years, silicon’s role in integrated optics has been successfully transformed from substrate material to guiding material. In fact, a lot of works in the past have shown that the silicon planar and rib waveguides can be fabricated with low losses, and hence they can easily be adapted into the designs of many passive and active silicon-based devices.

明代中后期,随着商品经济的发展和市民阶层的壮大,"人本主义"思想开始出现,艺术家们从感性出发,开始关注社会风俗题材和世俗审美趣味,籍以表达对日常世俗生活的迷恋和对自然人性的追求。陈洪绶在其绘画作品中运用了大量的表达世俗情怀的传统吉祥纹样,同时吸收了两汉时期高雅古朴的画像石、画像砖纹样以及唐代的人物纹样,使得"世俗"和"高古"这一对立的审美范畴在传统装饰纹样层面上得到了和谐的统一。

第八届东亚资源再生技术国际会议

＜正＞A new type of adsorbent for anions removal was developed and tested. The preparation and the adsorption efficiency are described. Some anions, for example arsenic and phosphate, are either toxic or pollutant compound in aqueous environment and industrial wastewater that are commonly removed by chemical precipitation and iron exchange. In spite of the efficiency, great amount of hazardous sludge is produced in precipitation. In this research work, a natural porous material, diatomite, was used as carrying material for iron-based adsorbent. After the surface modification, Fe content on the surface of diatomite increased so that its color changed into red. The adsorptions of both original and modified diatomite for arsenic and phosphate were also tested. The results demonstrate that the adsorption capacity of diatomite was increased significantly by mean of modification with iron hydroxide. The adsorption capacity of modified diatomite for arsenic was 15 mg/g and for phosphate 5.68 mg/g. Competitive adsorption between phosphate and arsenic was also described. By regarding water as a valuable resource, the new adsorbent enhances also the recycling of process water and the winning of drinking water with advantages.

The Eighth Chinese Optoelectronics Symposium

作者： Y. K. Su, S. C. Wei and S. J. Chang Institute of Microelectronics & Department of Electrical Engineering National Cheng Kung University, tainan

GaN-based light emitting diodes (LEDs) with p-cap layers grown at various temperatures were fabricated. It was found that the LED with 900℃-grown p-cap layer could only endure negative 1100 V electrostatic discharge (BSD) pulses while the LED with 1040℃-grown p-cap layer could endure ESD pulses as high as negative 3500 V. It was also found that the ESD performances of the LEDs with 900 and 1040℃-grown p-cap layers were limited by the V-shape defects and the bonding pad design, respectively.
