There were specific differences in median touchapproach time (TA): Saguinus fuscicollis had a shorter TA time than that of S.


Tool approach time and nonoperation time are taken from past experience and approximated for modification into mathematical forms.


Due to the modern knowledge based approach time for generating a mesh can be reduced to one fourth of the time using modern commercial meshing tools.


However, in a real game the approach time depends very much on the position of opponent robots.


Therefore at least 3 to 5 transient tests are required to obtain one size distribution, which makes the approach time consuming and expensive.

When effective population size was larger than 40 or the intensity of selection was high (less than 50% selected), selection had a dramatic effect in reducing the time to approach the maximum point of genetic variance.


Also, firearms did not shoot far or accurately in 1776, so troop formations could take more time to approach the enemy.


Furthermore, the deformable model takes a considerable amount of time to approach the equilibrium state.


Initially the energy decay rate in all five realisations is about 1.3 times the lower bound, but increases over time to approach the upper bound.


Institutional consent is used in emergency situations when there is no time to approach the family for consent.

 This paper presents a target assignation method based on the criterion of the shortest average time to approach in a cooperative engagement scenario, where two teams of aircraft are engaged and the aircraft within a team share information with each other through a certain wireless network. For given relative geometry and airborne weapon configurations, the time to flight of each vehicle against each target can be predicted through properly modeling the engagement process. Under the assumption that the aircraft,... This paper presents a target assignation method based on the criterion of the shortest average time to approach in a cooperative engagement scenario, where two teams of aircraft are engaged and the aircraft within a team share information with each other through a certain wireless network. For given relative geometry and airborne weapon configurations, the time to flight of each vehicle against each target can be predicted through properly modeling the engagement process. Under the assumption that the aircraft, when be assigned a target, always tries to vanish the aiming error during its course to the lunch envelop, and hence its trajectories can be approximated via the ones driven by proportional guidance lows. Given that an analytical expression for trajectories is available, the time to approach is obtainable by numerical integration. Based upon this expression, a target assignation strategy is obtained that minimizes the average time to approach of the group of attacking aircraft.  提出了一种在无线网络的支持下,使得机群平均接近时间最短准则的目标分配方法。对于给定的敌我相对运动态势和机载武器配置,每一架飞机进入攻击位置的时间是可以通过适当的模型和算法计算出来。本文假定飞机在进入发射位置的过程中,一直在试图消除瞄准误差,因而可以采用比例导引律来逼近其航路,由此可以得到飞机应飞时间的积分表达式。以此表达式为基础,以机群整体占位时间最小,本文得到了一个目标分配策略。  Air battle under command of AWACS had already became main develop direction of intermediaterang and longrang air fight in the future. Target information is studied which is measured by AWACS and address a few kinds of guidance laws of fighter, guided by AWACS which are pureproportion navigation, parallelapproach navigation and timeoptimum navigation. The mathematics models of AWACS, fighter and target are established, and simulation is carried out for the whole process of fighter guided by AWACS.  预警机指挥下的空战已经成为未来中远程空战的主要发展方向。文中研究了预警机对于目标信息的测算,提出应用纯比例、平行接近、时间最优等几种不同方法对战斗机实施导引。在此基础上建立了预警机、战斗机、目标的数学模型,并对预警机引导战斗机至目标区域整个过程进行了仿真。仿真结果表明,基于时间最优的导引方法适合于预警机对现代战斗机的导引控制。
