This paper presents an improved approach for detecting copy-move forgery based on singular value decomposition(SVD).It is a block-based method where the image is scanned from left to right and top to down by a sliding window with a determined *** each step,the SVD is ***,the diagonal matrix’s maximum value(norm)is selected(representing the scaling factor for SVD and a fixed value for each set of matrix elements even when rotating thematrix or scaled).Then,the similar norms are grouped,and each leading group is separated into many subgroups(elements of each subgroup are neighbors)according to 8-adjacency(the subgroups for each leading group must be far from others by a specific distance).After that,a weight is assigned for each subgroup to classify the image as forgery or ***,the F1 score of the proposed system is measured,reaching 99.1%.This approach is robust against rotation,scaling,noisy images,and illumination *** is compared with other similarmethods and presents very promised results.

Marine Life Science & Technology 2022年第1期4卷 127-137页

作者： Shen Fan Meng Wang Wei Ding Yong-Xin Li Yu-Zhong Zhang Weipeng Zhang College of Marine Life Sciences Ocean University of ChinaQingdao266003China State Key Laboratory of Microbial Technology Shandong UniversityQingdao266237China Department of Chemistry The University of Hong KongHong KongChina

The hadal zone is the deepest point in the ocean with a depth that exceeds 6000 m. Exploration of the biological communities in hadal zone began in the 1950s (the first wave of hadal exploration) and substantial advances have been made since the turn of the twenty-first century (the second wave of hadal exploration), resulting in a focus on the hadal sphere as a research hotspot because of its unique physical and chemical conditions. A variety of prokaryotes are found in the hadal zone. The mechanisms used by these prokaryotes to manage the high hydrostatic pressures and acquire energy from the environment are of substantial interest. Moreover, the symbioses between microbes and hadal animals have barely been studied. In addition, equipment has been developed that can now mimic hadal environments in the laboratory and allow cultivation of microbes under simulated in situ pressure. This review provides a brief summary of recent progress in the mechanisms by which microbes adapt to high hydrostatic pressures, manage limited energy resources and coexist with animals in the hadal zone, as well as technical developments in the exploration of hadal microbial life.

地区科技与经济的协调发展是当今经济社会发展的主题之一，该方面研究主要涵盖协调性概念、判断与评价标准、预警以及对策与措施四方面内容。基于数据包络分析方法(DEA)建立的综合评价模型直接从作用的有效和无效角度出发，能客观衡量地区科技发展与经济发展的耦合效果。实证研究表明，东部地区科技发展与经济发展协调性较好，中西部地区则一般或较差；东部应重视科技资源的使用效率，中西部则应重视科技成果的转化，加大科技资源的投入，发挥科技发展对经济发展的带动作用。

如何促进印度的技术发展

如何促进印度的技术发展

作者： BALAD VRUSHTI JITENDRA 浙江大学

学位级别：硕士

India's growing importance in global technological advancements is evident through its partnership with the US in cutting-edge technologies such as 5G,6G,quantum computing,and space *** Minister Modi's recent visit to the US in July 2023 holds significant global implications,including potential trade,technology,defence,and climate change *** has been steadily making strides both regionally and *** further elevate its profile,strengthening its technological prowess is *** has methodically nurtured its tech capabilities over the years,positioning itself for international acclaim,particularly in the IT *** research aims to uncover the path to nurturing technology in India while confronting the hurdles obstructing its economic and technological *** seeks to gauge India's impending global significance,particularly in the technology sector,which has become a favoured hub for outsourcing tech-related *** study aims to examine and understand how India has achieved such technological advancements and what are the implications to the international relations and what are the remaining challenges it *** the purpose of this study,this research involves examining India's policy both internally and internationally;as well as a more detailed case *** also engages some comprehensive examinations of other countries,such as the US and China to see what lacks for India advancing it high technology development.I argue that incorporating the outlined recommendations,India can chart a path to global technology leadership,promoting economic growth,job creation,and societal advancement through sustained collaboration among government,academia,industry,and stakeholders while customizing best practices to its unique socio-economic context.

“道”与“实践智慧”：技术发展模式的比较

科学技术哲学 2011年第11期 283-288页

作者：王前朱勤

中国传统哲学的“道”与亚里士多德的“实践智慧”有某些共同之处，同时也有根本差别。比较两者的共性与差别，不仅有助于理解中国和西方技术发展的不同模式，而且对处理当代科学技术与社会的关系有重要启发意义。“实践智慧”立足于西... 详细信息

中国传统哲学的“道”与亚里士多德的“实践智慧”有某些共同之处，同时也有根本差别。比较两者的共性与差别，不仅有助于理解中国和西方技术发展的不同模式，而且对处理当代科学技术与社会的关系有重要启发意义。“实践智慧”立足于西方文化传统，对于逻辑思维是非常有益的补充。而“道”的观念则提供了控制技术发展后果的另一种思路，具有更大的启发性。这一思路通过与“实践智慧”相互补充，将有助于引导技术走向和谐的发展模式。
