Aiming at the air defense task requirements for an enemy’s large-scale aircraft attack, this paper presents a plan generation algorithm which can quickly give interception scheme. The main contribution of is modification standard A* and its combination optimization air-defence mission. Firstly, attack weapon our platform are modeled, kinetic equations efficiency functions constructed, intercept...

Trees play a crucial role in the water, carbon and nitrogen cycle on local, regional and global scales. Understanding the exchange of momentum, heat, water, and CO 2 between trees and the atmosphere is important to assess the impact of drought, deforestation and climate change. Unfortunately, ground measurements of tree properties such as mass and canopy interception of precipitation are often ...

the main goal of this study was to compare of rainfall interception (i) by pinus eldarica and cupressus arizonica plantations afforested in the chitgar forest park in a semiarid climate zone of iran. from the september 2012 to september 2013, gross rainfall (gr) and throughfall (tf) were collected through 10 and 50 rain-gauges, respectively. i was calculated as the difference between gr and tf....

In maize, grain yield is highly associated with light interception and photosynthetic activity during grain filling. In Europe, this period typically occurs when solar radiation is already decreasing and water availability may be limiting. The improvement of cold-tolerance is a major challenge for maize production because earlier sowing would allow a better fit between crop cycle and availabili...

A semidistributed, physical-based Urban Forest Effects – Hydrology (UFORE-Hydro) model was created to simulate and study tree effects on urban hydrology and guide management of urban runoff at the catchment scale. The model simulates hydrological processes of precipitation, interception, evaporation, infiltration, and runoff using data inputs of weather, elevation, and land cover along with nin...

There is increasing interest in evaluating the environmental effects on crop architectural traits and yield improvement. However, crop models describing the dynamic changes in canopy structure with environmental conditions and the complex interactions between canopy structure, light interception, and dry mass production are only gradually emerging. Using tomato (Solanum lycopersicum L.) as a mo...

The exact mechanisms by which humans control the manual interception of moving targets are currently unknown. Here, the authors explored the behaviors associated with the spatial control for manual interception. The examined task required controlling a cursor to intercept moving targets on a touch screen. They explored the effects of target motion direction, curvature and occlusion on manual in...

ion is the removal of rain from surface runoff processes. In addition to infiltration, it includes surface depressional storage and vegetative interception, of which surface depressional storage is of greater importance. Initial abstraction is the surface depressional storage, vegetative interception and infiltration (Fs for the GAML model) prior to the start of runoff. Most of the total surfac...

The aims of this study were to assess the potential radioactive contamination of fodder in the case of accidental radionuclide fallout, and to analyse the relationship between interception and retention of radionuclides as a function of biomass and Leaf Area Index (LAI). The interception and the retention of wet deposited (134)Cs and (85)Sr in ley (a mixture of grass and clover) were measured a...
