    • An antenna array formed on a deformable dielectric material or substrate includes a center element and plurality of radial elements extending from a center hub. In the operative mode, the radial elements are folded upwardly into an approximately vertical position, with the center element at the center of the hub and the radial elements circumferentially surrounding the center element. In one embodiment the center element serves an active element of the antenna array and the radial elements are controllable in a directive or reflective state to effect a directive beam pattern from the antenna array. When not in use, the antenna elements are deformed into a plane and can therefore be integrated into a housing for compact storage. In a phased array embodiment, the center element is absent and the plurality of radial elements, are controllable to steer the antenna beam.
    • 形成在可变形电介质材料或衬底上的天线阵列包括中心元件和从中心毂延伸的多个径向元件。 在操作模式中,径向元件向上折叠成大致垂直的位置,中心元件位于毂的中心,而径向元件周向围绕中心元件。 在一个实施例中,中心元件用于天线阵列的有源元件,并且径向元件可以以指示或反射状态控制,以实现来自天线阵列的指向波束图案。 当不使用时,天线元件变形成平面,因此可以集成到壳体中以进行紧凑的存储。 在相控阵实施例中,中心元件不存在并且多个径向元件是可控的以引导天线波束。

    • A method is provided for determining a rating of a likelihood of a victim system receiving malicious traffic from an attacker system at a point in time. The method comprises: generating a first forecast from a time series model based on past history of attacks by the attacker system; generating a second forecast from a victim neighborhood model based on similarity between the victim system and peer victim systems; generating a third forecast from a joint attacker-victim neighborhood model based on correlation between a group of attacker systems including the attacker system and a group of victim systems including the victim system; and determining the rating of the likelihood of the victim system receiving malicious traffic from the attacker system at the point in time based on the first forecast, the second forecast, and the third forecast.
    • 提供了一种用于确定受害者系统在某个时间点从攻击者系统接收恶意流量的可能性的等级的方法。 该方法包括:基于攻击者系统的攻击历史,从时间序列模型生成第一预测; 基于受害者系统和同伴受害者系统之间的相似性,从受害者邻域模型生成第二预测; 基于包括攻击者系统在内的一组攻击者系统和包括受害者系统在内的一组受害者系统之间的相关性,从联合攻击者 - 受害者邻域模型产生第三预测; 以及基于所述第一预测,所述第二预测和所述第三预测,确定所述受害者系统在所述时间点从所述攻击者系统接收到恶意流量的可能性的等级。
