摘要： The embodiments present a new class of content masking attacks against the Portable Document Format (PDF) standard. The attacks cause documents to appear different than the underlying content extracted from the documents by information-based services. The first attack allows academic paper writers and reviewers to collude via subverting the automatic reviewer assignment systems in current use by academic conferences. The second attack renders plagiarism detection software ineffective, targeting specific small plagiarism similarity scores to appear natural and evade detection. The final attack places masked content into the indexes for various search engines, which renders as information entirely different from the keywords used to locate it. The final attack enables spam, profane, or possibly illegal content to go unnoticed by these search engines but still be returned in search results.

摘要： Weighing apparatus includes support means to support the article to be weighed, a pair of screws fixedly mounted on the support means and a base member movable relative to the screws between a first position in which the base member is spaced from the bottom of the article and a second position in which the base member is in contact with the article. Screw receiving members are threadably mounted on the screws and are connected to the base member. Upon rotation of the screw receiving members, the base member is moved between the first and second positions.

摘要： An apparatus and method for sensing electro-magnetic radiation and analysing the resultant electrical signal waveform, in order to determine whether the radiation originates from a fire condition, monitors variations in the signal waveform over a predetermined period of time. The amplitudes of the successive transitions in the waveform and the elapsed time between the transitions are measured. Two two-dimensional matrices are produced. The first of these is made up of a plurality of co-ordinate points each corresponding to a respective pair of successively occurring signal transitions. The position of each such point in the matrix is dependent on the respective amplitudes of the two transitions making up each pair. The second matrix is also made up of a plurality of co-ordinate points each corresponding to a respective pair of the signal transitions. In the second matrix, however, the position of each point within the matrix depends on the amplitude excursion and the elapsed time between the two transitions of each pair. The matrices thus produced are compared with predetermined matrices corresponding, for example, to predetermined fire conditions or false alarm conditions, whereby to determine whether the sensed radiation has a pattern corresponding to a fire or a false alarm situation.
摘要翻译：一种用于感测电磁辐射并分析所得到的电信号波形的装置和方法，以便确定辐射是否起源于火情，监视在预定时间段内信号波形的变化。测量波形中连续转换的幅度和转换之间的经过时间。产生两个二维矩阵。其中的第一个由多个坐标点组成，每个坐标点对应于相应的一对连续发生的信号转换。矩阵中每个这样的点的位置取决于构成每对的两个跃迁的相应振幅。第二矩阵也由多个坐标点构成，每个坐标点对应于相应的一对信号转换。然而，在第二矩阵中，矩阵内的每个点的位置取决于每对的两个转变之间的振幅偏移和经过的时间。将如此产生的矩阵与例如对应于预定的火情或假警报状况的预定矩阵进行比较，从而确定所感测的辐射是否具有对应于火灾或虚假警报情况的模式。
