Structural noise is an important factor that endangers aircraft fatigue life and flight safety. It also has a negative effect on aircraft stealth performance and noise navigability. An optimal design of a structure-acoustic coupled system is an effective way to reduce noise and vibration. Due to the uncertainties that exist in the structural and acoustical parameters, the traditional determinis...

This study investigates variations in how users exert agency and control over their choice patterns within the game-based ITS, iSTART-2, and how these individual differences relate to performance. Seventy-six college students interacted freely with iSTART-2 for approximately 2 hours. The current work captures and classifies variations in students’ behavior patterns using three novel statistical...

Users and providers increasingly disagree on what Denial of Service (DoS) is. For example, an ISP might consider large multimedia downloads an attack to overload its infrastructure or have it pay high interconnection fees. On the other hand, a user will certainly consider selective bandwidth reduction that is used by ISPs as a countermeasure, as a DoS measure. Given the nature of their business...

We are using stealth assessment, embedded in Plants vs. Zombies 2, to measure middle-school students’ problem solving skills. This project started by developing a problem solving competency model based on a thorough review of the literature. Next, we identified relevant in-game indicators that would provide evidence about students’ levels on the various problem-solving facets. Our problem solvi...

The current study examines the influence of corporate frontpaigns. Corporate front-group stealth campaigns are based on s deceive receivers. When companies work together collectively, a disguise true interests, they are utilizing front groups; when fron campaigns using names that deceive, they are engaged in stealth examines the influence of this approach, which is based on cor badly, engaged i...
