基于移动多核GPU的并行二维DCT变换实现方法     

龚若皓  杨斌 《成都信息工程学院学报》2015,30(1):22-26

传统的基于CPU的串行程序所实现的二维DCT变换算法时间复杂度高变换效率低,难以满足许多应用的实时要求。特别是在当代以嵌入式处理器为核心的移动端信息处理终端,有限的CPU性能更加难以实现快速的DCT变换。值得欣慰的是新一代嵌入式处理器提供了支持GPGPU技术的GPU,为解决复杂的移动计算问题提供了高效的并行化解决途径。基于最新的ARM Cortex-A15内嵌GPU Mali-T604及Open CL框架设计实现了一种针对二维DCT变换的并行化加速方案并实测了优化效果,实验结果表明文中的并行方案能够提高二维DCT变换的效率,在输入数据量足够大的条件下能够达到近20倍的加速比。  相似文献

Empowering farmers with remote sensing knowledge: A success story from the US Upper Midwest     

S. K. Seelan  D. Baumgartner  G. M. Casady  V. Nangia  G. A. Seielstad 《国际地球制图》2013,28(2):141-157

Satellite imagery has proven potential in farm level applications, especially in the US Upper Midwest where the farm sizes are large enough to be studied using high and medium resolutions. In order for farmers to use this technology to improve their productivity and income, it is imperative that they be sufficiently exposed to the technology so that they are able to take full advantage of it. Training of farmers and ranchers in satellite imagery use started at the University of North Dakota in 2000 and has been refined over time. The basic ‘hands on’ training involves downloading imagery from the Upper Midwest Aerospace Consortium (UMAC) website, downloading and use of free visualization software programs available on the web and an introduction to the various application possibilities. Advanced training, which involves more complex extraction of useful information from digital images, is also available to those who complete the basic training. Over 500 farmers, ranchers, crop consultants and other end users have been trained through this programme and the results are beginning to show through the success stories of cost savings and environmental benefits that have emerged.  相似文献   

British National Report to the International Cartographic Association for the Period 2011-2015     

David Forrest 《The Cartographic journal》2013,50(3):213-214

In recent years, the concepts of usability, user experience, and user-centricity have gained in interest. Digital applications, developed in line with criteria related to these approaches, ask for a deeper understanding of users and their requirements. But, even though there is a wide range of methods available, the creation of user-centric applications with good usability and user experience still poses great challenges for developers. This is also true for web maps, i.e. web map applications, which today are ubiquitous on the Internet. They have evolved into an important information and communication tool and address users who do not possess any specific knowledge of Geoinformatics (GI) or Cartography. Despite the efforts made to meet the requirements and preferences of laymen, these users still often face problems when dealing with web map applications. This refers to aspects of design, content, and functionality. Here, participatory design, which is well-known in the field of Software and Web Engineering, might provide a suitable means. By engaging users directly and actively in the application development process, developers are able to gain a profound understanding of the users and their needs. However, there are several open questions regarding the use of participatory design for designing and implementing web map applications: What does the use of participatory design in web map development processes look like in detail? How and to what degree can users be involved in the development processes? Which added values exist? These questions are addressed by the project YouthMap 5020, whose main goal it was to create a prototype youth-centric web map for the Austrian city of Salzburg (zip code 5020). Applying the approach of participatory design, about 120 teenage pupils from several local schools were involved in all kinds of tasks related to the phases of generating the youth-centric Salzburg web city map. Experience and knowledge gained thereby allowed elaborating recommendations generally useful for generating youth-centric web map applications.  相似文献

城镇化与生态环境耦合是当前研究热点,而其动态模拟将是未来的重要方向。基于系统科学与跨尺度耦合理论揭示城镇化与生态环境耦合系统的本质,即一个非线性的、具有高低阶多重反馈的开放的复杂巨系统。通过综述城镇化与生态环境耦合动态模拟的理论、方法与应用的研究进展,可知：① 动态模拟成为趋势,相关理论与机理解析不断完善;② 动态模拟技术趋向多元化、精细化、智能化和集成化;③ 应用研究基于多类型案例区、多要素以及近远程与跨区域3个方面。当前研究不足包括：① 理论发展与整合不足;② 方法集成与数据共享力度滞后;③ 耦合关系链条和主控要素的动态特征未被完整揭示,远程耦合模拟缺乏定量表达、系统性整合以及与区域联动层面的应用衔接。今后,应以理论为根基,推动多科学交叉融合;以方法为支撑,推动动态模拟技术整合与数据共享;以应用为导向,揭示城市群等重点地区的近远程关系链条与主控要素的动态演化模式,为区域可持续城镇化提供决策支持。  相似文献   

GGR Biennial Review: Key Advances in Secondary Ion Mass Spectrometry in the Geological Sciences during the Period 2008–2009     

Michael Wiedenbeck 《Geostandards and Geoanalytical Research》2010,34(4):387-394

Secondary ion mass spectrometry (SIMS or ion microprobe) remains one of the most powerful techniques in the analytical geochemist’s toolkit. The key strength of SIMS is its capacity to provide trace element and isotope data at sampling sizes which are not approached by other methods. As compared with the main competing technique of laser ablation-ICP-MS, SIMS commonly provides a total sampling mass some 10 to 500 times smaller; this feature can be the deciding factor as to whether an analytical objective is technically achievable. Additional strengths of SIMS lie in the areas of depth profiling and trace element imaging. Though perhaps not as commonly used in the geosciences, these two operational modes represent unique capabilities of SIMS.  相似文献   

Marine genetic resources: A review of scientific and commercial interest     

David Leary  Marjo Vierros  Gwenaëlle Hamon  Salvatore Arico  Catherine Monagle 《Marine Policy》2009

Marine genetic resources both within and beyond national jurisdiction have been the focus of international negotiations in a range of forums in recent years. One recurrent theme throughout these discussions has been the absence of detailed information upon which policy responses to the emerging issue of the conservation and sustainable use of marine genetic resources (especially in areas beyond national jurisdiction) could be based. In an effort to address some of these knowledge gaps, this article examines the level and nature of scientific and commercial interest in marine genetic resources, including in areas beyond national jurisdiction. It also examines the changing perspectives of the scientific community in relation to the potential of marine genetic resources.  相似文献
