基于全覆盖路径规划的地面搜索问题研究     

杨恒伏  田祖伟 《湖南第一师范学报》2009,9(1):159-162

对简化的地面搜索问题进行研究。首先用最小覆盖原理求出组内每个人的实际搜索半径;考虑组内所有搜索队员作为一个整体沿区域扫描线方向进行搜索,从而可导出一组搜索队伍总的搜索宽度;然后用搜索队伍总的搜索宽度对目标区域进行栅格化;最后采用基于栅格地图的全覆盖路径规划算法对问题1进行求解。对问题2。首先根据时间均衡原则和各组人数均衡原则,确定好各组人数与各组区域优化分配,于是问题2就转化为问题1,便可采用问题1的模型进行求解。理论分析与计算结果表明该方案是可行的。  相似文献   

基于光谱混合分析的城市植被覆盖度与地表温度关系的研究     

李华朋  张树清  孙妍 《中国科学院大学学报》2010,27(6):739-747

分别选择NDVI和光谱混合分析植被组分(VF)作为城市植被覆盖度指示因子,研究植被覆盖度与地表温度(LST)的相关关系.选择了一定数量的样本点,通过线性拟合的方法研究了NDVI及VF与LST的相关关系.研究结果表明,VF与LST之间的相关性比NDVI与LST之间相关性更好.研究表明,在城市LST研究中VF可以作为表征植被性质的参数.  相似文献   

论焦裕禄精神与党性修养     

楚克松 《商丘职业技术学院学报》2009,8(4):4-6

目前,党性修养问题已引起党和国家的高度重视,焦裕禄则以他共产党员的坚定党性引起了广泛关注。当前,我国面临的国内外形势、部分领导干部存在的作风、党性修养在领导干部作风中的＂根本＂性地位等,都要求我们必须大力弘扬焦裕禄精神,进一步加强党性修养。加强党性修养是共产党人引领社会主义事业不断前进的唯一保证。党性修养的主要内容包括党性内涵等三个方面,其基本途径则包括确立信仰等五个方面。  相似文献

People's Daily: An Evolutionary Narrative on Asia in Its Coverage of the Asian Games     

Wenting Xue 《国际体育史杂志》2013,30(10):1037-1047

Amid the complex international situation and entangled interests, news narration is usually conducted by the government, media and the public together by copying mainstream ideas and concepts. In covering the Asian Games, People's Daily takes on a periodical change in its narration about Asia during the history of China's participation in the Games: in the stage of ‘alienation and struggle’, the narration is focused on politics; in the stage of ‘participation and competition’, the narration becomes two dimensional, touching on both politics and sport; in the stage of ‘hosting the Games and taking the lead’, the narration is further diversified and incorporates politics, sport and culture. Such an evolution takes place in a profound international and historical context, reflecting the changes not only in China's sporting events coverage but also in the ‘mindset and insight’ of Chinese media in covering sporting events and Asia.  相似文献   

Flags,Feuds and Frictions: North Korea and the London 2012 Olympics     

Udo Merkel 《国际体育史杂志》2013,30(15):1810-1822

The Democratic People's Republic of Korea participated in the 2012 Summer Olympics in London with 51 athletes. They won a total of six medals and finished 20th in the overall medal table. However, most observers of the London 2012 Olympics will not remember North Korea's athletic successes but the flag blunder that kicked the Games off with a diplomatic row. On the first day, the South Korean flag was accidentally displayed next to the faces of the North Korean women's football team on the stadium's huge screen. Although there have been several flag controversies and blunders in the context of the Olympic Games, this incident must be considered as one of the most embarrassing and high-profile as, technically, North and South Korea are still at war having signed only an armistice at the end of the Korean War in 1953. This paper deals with three interrelated issues: first, it outlines the development of inter-Korean political and sporting relations since the 2008 Beijing Olympics before, second, it focuses on the political significance of the 2012 London Games. Third, it summarises key themes and ideological messages emerging from a qualitative analysis of the state-controlled North Korean media coverage of the 2012 Olympics. The Korean Central News Agency appears to pursue a dual strategy: it aims to increase the popularity of outstanding North Korean athletes and create home-grown stars, and also attempts to encourage an alternative discourse about the country abroad. All these issues need to be analysed in wider context of significant political changes in both Koreas, particularly in the North, where Kim Jong-un, who came to power in December 2011, has started to carve out a distinct identity and forge his own leadership style.  相似文献

"后散文"的"后"景观     

陈挚 《四川教育学院学报》2006,22(5):48-49,53

“后散文”就是这样一种姿态的散文，它不属于任何流派，也不带浓厚的技术痕迹。我们所看到的，既有内心的，也有文化的；既有主流的，也有边缘的。各种文化、思想和风格在“后散文丛书”中得到了充分展现。从中我们能读到这种市场之“后”的“非媒体散文”，它不时尚，不急躁，不过分自我，能包容对世界的不同看法。或许，正是这样的写作，才更有可能抵达写作的本来意义；让文字与思想、与命运、与灵魂真正融合。  相似文献   

基于贝叶斯网络的验证激励向量生成研究     

王润  蒋剑飞  王琴 《教育技术导刊》2020,19(7):1-4

为了解决传统数字芯片验证环节中基于仿真的验证（或动态验证）功能覆盖率收敛速度慢的缺点,提出一种新的以功能覆盖为导向的测试用例生成方法,该方法基于贝叶斯网络和机器学习技术,可实现从覆盖模型到测试用例生成器反馈回路的自动关闭,在 DUT 的验证过程中,使用该方法为所测试的设计生成新的激励。实验结果表明,基于贝叶斯网络的 CDG 技术测试用例使用较少,覆盖率收敛更快,与传统基于仿真的验证技术相比,测试用例数量减少了 43%。基于贝叶斯网络的 比于传统动态验证技术而言其芯片功能验证更完善。  相似文献   

中国学生贷款补贴体系的演变与发展趋势     

季俊杰 《云南师范大学学报(哲学社会科学版)》2012,44(1):105-110

中国学生贷款现有贴息、税前扣除、特定免税、风险补偿金、代偿、利率补贴等6种补贴形式,它们又可分为显性直接补贴、隐性直接补贴和显性间接补贴、隐性间接补贴四种补贴方式,以及"政府补贴学生"、"银行补贴学生"、"政府补贴银行"三种主客体关系。实践表明,中国学生贷款补贴扩大了资助面,减轻了学生还贷负担,缓解了国家助学贷款的获贷难和回收难问题。今后补贴规模还应进一步加大,并辅之以补贴结构的优化。  相似文献
