    • An edge sharpness measurement apparatus includes a clamp for securing a test medium against a frictional member, and an engagement mechanism for a normal force, such that the normal force directs the test medium against the frictional member with a force based on operational conditions of the test medium. A further engagement mechanism is for a tangential force, in which the engagement mechanism is adapted to increase the tangential force to identify a tangential force sufficient to dispose the frictional member across the test medium. A pivot defines an angle of application of the tangential force relative to the normal force, such that disposing the frictional member across the test medium defines a point of overcoming frictional forces between the test medium and the frictional member. A measurement device, such as a gauge or range on a spring, measures the tangential force sufficient to dispose the frictional member.
    • 边缘锐度测量装置包括用于将测试介质固定在摩擦构件上的夹具和用于法向力的接合机构,使得法向力基于测试的操作条件用力将测试介质抵靠摩擦构件 中。 进一步的接合机构用于切向力,其中接合机构适于增加切向力以识别足以将摩擦构件设置在测试介质上的切向力。 枢轴限定相对于法向力的切向力的施加角度,使得在测试介质上布置摩擦构件限定了克服测试介质和摩擦构件之间的摩擦力的点。 测量装置,例如弹簧上的量规或范围,测量足以设置摩擦构件的切向力。

    • Rules, applied to deny authorization of likely fraudulent transactions, are derived from a modified Patient Rule Induction Method algorithm that uses a target variable and a data set of past transactions each associated with a plurality of input variables and a hyper-rectangle enclosing a multi-dimensional space defined by a representation of the input variable values as points within the multi-dimensional space. While a count of the points within the hyper-rectangle is greater than a minimum support parameter, a first plurality of points proximal to edges of the hyper-rectangle are removed, where each such removing maximizes a mean value of the target variable, and then, while the mean value remains maximized, a second plurality of points proximal to the edges is added, where each adding maximizes or maintains the mean value. The hyper-rectangle is bounded within a minimum bounding box that defines the rules.
    • 应用于拒绝对可能的欺诈交易的授权的规则来自修改的患者规则诱导方法算法,该算法使用目标变量和与多个输入变量相关联的过去交易的数据集,以及包围多个输入变量的超矩形, 由输入变量值的表示定义的多维空间作为多维空间内的点。 虽然超矩形内的点的计数大于最小支持参数,但是去除超矩形边缘附近的第一多个点,其中每个这样的移除最大化目标变量的平均值,然后 当平均值保持最大时,添加靠近边缘的第二多个点,其中每个添加最大化或维持平均值。 超矩形在定义规则的最小边界框内是有界的。
