Engineering point defects such as metal and oxygen vacancies play a crucial role in manipulating the electrical,optical,and catalytic properties of oxide semiconductors for solar water ***,we synthesized nanoporous CuBi_(2)O_(4)(np-CBO)photocathodes and engineered their surface point defects via rapid thermal processing(RTP)in controlled atmospheres(O_(2),N_(2),and vacuum).We found that the O_(2)-RTP treatment of np-CBO increased the charge carrier density effectively without hampering the nanoporous morphology,which was attributed to the formation of copper vacancies(VCu).Further analyses revealed that the amounts of oxygen vacancies(Vo)and Cu^(1+)were reduced simultaneously,and the relative electrochemical active surface area increased after the O_(2)-RTP ***,the point defects(VC_(u),Cu^(1+),and Vo)regulated np-CBO achieved a superb water-splitting photocurrent density of-1.81 m A cm^(-2) under simulated sunlight illumination,which is attributed to the enhanced charge transport and transfer properties resulting from the regulated surface point ***,the reversibility of the formation of the point defects was checked by sequential RTP treatments(O_(2)-N_(2)-O_(2)-N_(2)),demonstrating the strong dependence of photocurrent response on the RTP ***,the surface point defect engineering via RTP treatment in a controlled atmosphere is a rapid and facile strategy to promote charge transport and transfer properties of photoelectrodes for efficient solar water-splitting.

Self Localization Method using Parallel Projection Model for Mobile Sensor in Navigation Applications

引用

Journal of Computer Science & Technology 2009年第3期24卷 588-603页

作者： Shung Han cho Yuntai Kyong Sangjin Hong We-Duke cho Department of Electrical and Computer Engineering Stony Brook University- SUNY Stony Brook NY U.S.A. Department of Electronics Engineering College of Information Technology Ajou University Suwon Korea

This paper presents a novel self localization method using parallel projection model for mobile sensor in navigation applications. The algorithm estimates the coordinate and the orientation of mobile sensor using projected references on visual image. The proposed method considers the lens non-linearity of the camera and compensates the distortion by using a calibration table. The method determines the coordinates and orientations with iterative process, which is very accurate with low computational demand. We identify various sources of error on the coordinate and orientation estimations, and present both static sensitivity analysis of the algorithm and dynamic behavior of the mobile sensor. The algorithm can be utilized in mobile robot navigation as well as positioning application where accurate self localization is necessary.

日照是影响人们身体健康的重要因素,学生宿舍作为青年学生长时间居住的场所,其日照情况有必要得到重视。我国北方寒冷地区高校学生宿舍多采用南北朝向的内廊式建筑形式,导致约一半宿舍单元长期无日照,给学生健康带来明显不利的影响。在“健康中国”战略大背景下,如何使更多寒冷地区学生宿舍获得基本日照,是未来该类建筑设计中需要关注和解决的重要问题。文章以西安某大学宿舍区为例,从建筑朝向和群体布局两个方面提出宿舍区再设计策略,可为西安地区高校u字形内廊式学生宿舍建筑的日照优化设计提供依据,相关研究方法可为同类气候区其他建筑的日照优化设计提供参考。
