Communications Interception is an essential part of law enforcement used by authorised government agencies to investigate criminal activities. With the growth of IP based applications and new IP technologies such as mobile IP, Internet Service Providers (ISPs) will find themselves increasingly obliged to provide interception capabilities. IP interception is usually done with expensive hardware ...

Merchant, Hugo and Apostolos P. Georgopoulos. Neurophysiology of perceptual and motor aspects of interception. J Neurophysiol 95: 1–13, 2006; doi:10.1152/jn.00422.2005. The interception of moving targets is a complex activity that involves a dynamic interplay of several perceptual and motor processes and therefore involves a rich interaction among several brain areas. Although the behavioral as...

This paper presents a novel on-line trajectory planning method for the autonomous robotic interception of moving targets in the presence of dynamic obstacles, i.e., position and velocity matching (also referred to as rendezvous). The novelty of the proposed time-optimal interception method is that it directly considers the dynamics of the obstacles as well as the target in its interception mane...

Vegetation cover plays an essential role in the vertical and horizontal distribution of rainwater. As rainwater passes through canopy, it can be divided into interception loss, throughfall, stemflow. In areas where yerba mate is cultivated, loss influences variability water reaching soil, surface runoff, nutrient cycling. The objective this study was to evaluate stemflow, ( Iex paraguariensis )...

Accurately quantifying the vegetation rainfall interception at a high resolution is critical for rainfall-runoff modeling and flood forecasting, and is also essential for understanding its further impact on local, regional, and even global water cycle dynamics. In this study, the Remote Sensing-based Gash model (RS-Gash model) is developed based on a modified Gash model for interception loss es...

A one-dimensional mass and energy balance model was developed to simulate rainfall interception in Sacramento County, California. The model describes tree interception processes: gross precipitation, leaf drip, stem flow, and evaporation. Kriging was used to extend existing meteorological point data over the region. Regional land use/ land cover and tree canopy cover were parameterized with dat...

Eye movements aid visual perception and guide actions such as reaching or grasping. Most previous work on eye-hand coordination has focused on saccadic eye movements. Here we show that smooth pursuit eye movement accuracy strongly predicts both interception accuracy and the strategy used to intercept a moving object. We developed a naturalistic task in which participants (n = 42 varsity basebal...

A new architecture, denoted as the Nyquist folding digital receiver (NYFDR), to compress the data for signal interception is presented. The NYFDR is a digital version of the Nyquist folding receiver (NYFR). Simulation results show that the NYFDR has advantages over NYFR in the detection of Nyquist zone. Moreover, the data rate and resource consumption of the NYFDR are less than those of the dig...

In the Internet, BGP is de facto inter-domain routing protocol. And it is vulnerable to a number of damaging attacks. Among these attacks, IP prefix hijacking and traffic interception are regarded as the serious threats in the Internet. There have been many incidents of IP prefix hijacking in the Internet. The hijacking AS can blackhole the hijacked traffic by introducing network unreachability...

Artificial night light has the potential to significantly alter visually-dependent species interactions. However, examples of disruptions of species interactions through changes in light remain rare and how artificial night light may alter predator-prey relationships are particularly understudied. In this study, we examined whether artificial night light could impact prey attraction and interce...
