Rainfall interception losses from an agroforestry system in semi-arid Kenya comprising Grevillea robusta and maize were measured over a period of 33 months. These measurements showed that interception was slightly higher (10.2%) under trees with no maize understorey, than in the intercropped treatment (9.8%), and was directly related to the degree of tree canopy cover. Interception estimates us...

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...

Leaf shapes of cotton (Gossypium hirsutum) range from highly divided leaves (okra leaf) to normal leaf shape (Meredith, 1 ). The variation in leaf shape results in differences in canopy architecture and light interception characteristics (Wells and Meredith, 1 ). Heitholt et al. (1 ) described higher yields of okra leaf isolines for a given amount of intercepted radiation, indicating that the o...

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...

In The Cancer Genome Atlas the goals were to define how to treat advanced cancers with targeted therapy. However, the challenges facing cancer interception for early detection and prevention include length bias in which current screening and surveillance approaches frequently miss rapidly progressing cancers that then present at advanced stages in the clinic with symptoms (underdiagnosis). In c...
