    • A domain-based spam-resistant ranking architecture that computes trust in a domain based on web-servers on which a domain is hosted and a set of other domains that link to the domain. The ranks of pages are computed based on how much trust there is in each domain and which pages link to it. Web documents are ranked in a spam-resistant manner by assigning uniform significance to each IP address of a network location and then assigning trust values to domains hosted on those IP addresses. Then, based on a domain graph, the invention constructs a domain-rank which is an estimate of how authoritative the domain is. The domain ranks are then used to assign a minimum rank to each document.
    • 基于域的基于垃圾邮件的排名体系结构,可以根据托管域的Web服务器和一组链接到该域的其他域来计算域中的信任。 页面的排名是根据每个域中的信任度以及链接到哪个页面来计算的。 通过为网络位置的每个IP地址分配均匀的重要性,然后为托管在这些IP地址上的域分配信任值,将Web文档排列为垃圾邮件的方式。 然后,基于域图,本发明构造了一个域级,其是该域的权威性的估计。 然后,域排名用于为每个文档分配最低等级。

    • Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for web page identification by propagating scores in a graph. In one aspect, a method identifies two or more web pages, wherein each web page is associated with one or more features, and each web page is associated with a respective first score, and each feature is associated with a respective second score. A graph is generated linking the two or more web pages and the one or more features. An updated first score is calculated for each web page and an updated second score is calculated for each feature. For each web page, a determination is made as to whether the respective updated first score meets a threshold. The web page associated with the updated first score that meets the threshold is identified as a web page that an advertiser can use as a landing page.
    • 方法,系统和装置,包括在计算机存储介质上编码的计算机程序,用于通过在图中传播分数来进行网页识别。 在一个方面,一种方法识别两个或多个网页,其中每个网页与一个或多个特征相关联,并且每个网页与相应的第一分数相关联,并且每个特征与相应的第二分数相关联。 生成链接两个或多个网页和一个或多个特征的图形。 为每个网页计算更新的第一分数,并为每个特征计算更新的第二分数。 对于每个网页,确定相应的更新的第一分数是否满足阈值。 与更新的第一分数相关联的满足阈值的网页被标识为广告商可以用作着陆页的网页。

    • Systems, methods, and computer-readable media are disclosed for evaluating data quality. An exemplary embodiment includes storing a plurality of records, the records sharing a common attribute, and reading first values for the common attribute corresponding to a first time period and second values for the common attribute corresponding to a second time period. A business rule for evaluating the common attribute is accessed, and first and second consistency data are generated. The first consistency data may reflect the extent to which the first values of the common attribute are consistent with the business rule at the first time. The second consistency data may reflect the extent to which the second values of the common attribute are consistent with the business rule at the second time. The first consistency data and the second consistency data are processed to generate a quality change rate of the common attribute from the first time period to the second time period, based on the difference between the first consistency data and the second consistency data.

    • A pneumatic-internal combustion (IC) engine based power management system with improved energy efficiency for automobile application. More particularly, the pneumatic IC engine based power management system comprises a compressor, a pressure vessel, a pneumatic motor and related control mechanisms to provide energy on demand and reduce environmental pollution. The compressor is driven by the IC engine during low power demand by the vehicle. The lightweight pressure vessel wrapped with high strength metal wire and/or fibers provide impact resistance adequate to store compressed air at rated pressure. For low/no load condition of engine or compressor, the IC engine will shut off rather than idling to save fuel. The stored compressed air drives the air motor that powers the vehicle's initial motion and then starts the IC engine to provide continuous power. A controller monitors the power demand and actuates different system components accordingly through sensors. The system also supports accessories such as air conditioning, heater etc. and a wheel-rim system for inflation maintenance and easy change over of tyres.
    • 一种基于气动内燃机的电力管理系统,具有改善汽车应用的能源效率。 更具体地,基于气动IC引擎的电力管理系统包括压缩机,压力容器,气动马达和相关的控制机构,以便按需提供能量并减少环境污染。 在车辆的低功率需求下,压缩机由IC发动机驱动。 用高强度金属丝和/或纤维包裹的轻质压力容器提供足以在额定压力下存储压缩空气的冲击强度。 对于发动机或压缩机的低/无负载状态,IC发动机将关闭而不是空转以节省燃料。 存储的压缩空气驱动空气马达,为车辆的初始运动提供动力,然后启动IC引擎以提供连续的动力。 控制器监控电力需求,并通过传感器相应地启动不同的系统组件。 该系统还支持空调,加热器等配件,以及用于充气维护和轮胎容易更换的轮辋系统。
