摘要： Several(generalized)hypergeometric functions and a variety of their extensions have been presented and investigated in the literature by many authors.In the present paper,we investigate four new hypergeometric functions in four variables and then establish several recursion formulas for these new functions.Also,some interesting particular cases and consequences of our results are discussed.

摘要： Climate change is one of the biggest challenges of our times.Global warming has caused extreme weather events,losses of species and their habitats,rising sea levels,and a range of other impacts.These pose fundamental threats to the livelihood of humans.“The speed at which temperatures are increasing is alarming,”said Pascal Peduzzi,director of GRID-Geneva at the United Nations Environment Program(UNEP).To fight climate change,all the countries must take action and reduce their greenhouse gas emissions.

摘要： Task 1 Word on the street is that gossip (流言) is the worst. An Ann Landers advice column once characterized it as "the faceless ghost that breaks hearts and ruins careers". The Talmud describes it as a sword that kills three people:the teller, the listener, and the person being gossiped about. And Blaise Pascal observed, not unreasonably, that if people really knew what others said about them.

摘要： 高精度数据算法是一种处理大数字的数学计算方法,是运用计算机对超大数据进行的模拟运算。在信息技术教学中,高精度数据算法的内容可以锻炼学生的计算思维,增强学生的信息意识,从而全面提升学生的综合素质,帮助学生解决日常生活中的相关问题。依托高精度数据的算法探究来谈信息技术教学核心素养的渗透。

摘要： In The World Republic of Letters(1999,2004),Pascale Casanova analyzes the overlapping levels of power behind the global production and circulation of aesthetic style,literary prestige,and cultural capital.Influenced by scholars like Pierre Bourdieu,she offers us a sociological account of world literature by situating its world-making poiesis at the global intersection of aesthetics and politics.In other words,this metaphorical world republic of letters,however cosmopolitan it aspires to become,betrays a hegemonic political economy in which Paris occupies the center of prestige and power,whereas minor literatures on the periphery are often rendered inferior,if not invisible.

摘要： 德尔斐(Delphi),泛希腊圣地代表,最初以非自愿形式植入我的视野一编程教材上具有催眠功效的铅字:宝蓝公司软件工程师丹尼.索普为避免歧义和技术窃听,借用古希腊女祭司皮堤亚的圣所德尔斐来命名Pascal面向对象扩展语言。原以为结课即是永别该词,孰料12年后,我竟伫立在帕尔纳索斯山南坡阿波罗神庙的遗址上,默念出这剂埋伏在记忆深处的药引,仿佛一曲缺席自然小调的多利亚调式,等来了久违的Cm6和弦。

摘要： 1648年,有一位法国物理学家表演了一个著名的实验。他用1个密闭的装满水的桶,在桶盖上插入1根细长的管子,从楼房的阳台上向细管子里灌水,结果只用了几杯水,就把桶压裂了,桶里的水从裂缝中流了出来。这对许多人来说是不可思议的。这就是历史上有名的帕斯卡桶裂实验,而这位法国物理学家就是布莱士·帕斯卡(Blaise Pascal)。

摘要： 随着GeForce RTX系和GTX 16系游戏显卡的全面铺开,图灵核心已经在市场上得到了玩家的广泛认可。不过除了强悍的游戏性能之外,图灵核心在NVENC上也进行了全新的升级,相比上一代的Pascal NVENC,它表现出了更流畅的游戏直播帧率和更清晰的游戏画面以及更低的CPU占用率。对喜好主播的玩家们来说,这无疑是个巨大的福音。当然,口说无凭,今天就让我们来实际体验一下,基于Turing核心的NVENC,到底有哪些“高人一等”的地方。

摘要： Aiming at the problem that constructing methods in hybrid encryption algorithms are fixed,a multi-crypto system hybrid encryption algorithm model based on RSA and Hill is proposed. Firstly,the plaintext is divided by a series of random numbers which are encrypted by the RSA cipher as a session key in the hybrid encryption algorithm.Then the key of Hill cipher is replaced by Pascal matrix whose generation algorithm has been improved.Security analysis and experimental results show that this encryption algorithm has better encryption efficiency and stronger anti-attack capacity.%针对混合加密算法构造方法固定的问题,提出了一种基于 RSA和 Hill的多密码体制混合加密算法模型.首先,根据生成的一系列随机数分割明文,将混合加密算法中会话密钥转换为明文的随机分割数,并使用RSA密码对其加密.然后,改进Pascal矩阵生成算法,用该算法生成的Pascal矩阵代替 Hill密码的密钥对明文加密.安全性分析和实验结果表明,该加密算法具有较强的抗攻击性和较好的加密效率.

摘要： 本发明涉及数字图像处理技术领域，提供一种基于广义Pascal映射的椭圆检测加速方法，包括：步骤100，利用椭圆检测方法中的边缘处理方法，从真实图像中提取较为准确的边缘点信息，并将边缘点连接成弧，将经过去噪处理后的弧集合，做为椭圆检测加速方法的输入；步骤200，利用广义Pascal映射，从步骤100输入的弧集合中筛选出可能属于同一个椭圆的有效候选弧组合；步骤300，计算候选椭圆的五个参数；依次重复步骤200到步骤300，直至找到弧集合中所有的有效候选弧组合及对应的候选椭圆；步骤400，对候选椭圆集进行聚类和验证，得到最终检测椭圆集。本发明能够减少无效椭圆拟合的计算，同时保证检测精确度。
