From an object-oriented programming perspective, an important class of aspects (in the sense of aspect-oriented programming) can be modelled via method call interception (MCI). This concept allows us to intercept transitions from a caller to a callee in a way that extra functionality can be superimposed on the actual method call. We describe fundamental language constructs for MCI. The style of...

Recent reports have highlighted incidents of massive Internet traffic interception executed by rerouting BGP paths across the globe (affecting banks, governments, entire network service providers, etc.). The potential impact of these attacks can range from massive eavesdropping to identity spoofing or selective content modification. In addition, executing such attacks does not require access or...

Proxy servers are being increasingly deployed at organizations for performance benefits; however, there still exists drawbacks in ease of client authentication in interception proxy mode mainly for Open Source Proxy Servers. Technically, an interception mode is not designed for client authentication, but implementation in certain organizations does require this feature. In this paper, we focus ...

Small cruising zooplankton depend on remote prey detection and active prey capture for efficient feeding. Direct, passive interception of prey is inherently very inefficient at low Reynolds numbers because the viscous boundary layer surrounding the approaching predator will push away potential prey. Yet, direct interception has been proposed to explain how rapidly cruising, blind copepods feed ...

A game-theoretic approach to the design of robust integrated guidance-control system for a moving-mass actuated kinetic warhead is presented. Feedback linearized form of the kinetic warhead dynamics and a high-order target model are used in the formulation. Nonlinear feedback solution to the robust finite-horizon target interception problem is derived using the recently developed multi-stepping...

People generally try to keep their eyes on a moving target that they intend to catch or hit. In the present study we first examined how important it is to do so. We did this by designing two interception tasks that promote different eye movements. In both tasks it was important to be accurate relative to both the moving target and the static environment. We found that performance was more varia...
