A key objective of cognitive modeling research at the Air Force Research Laboratory’s Warfighter Training Research Division is to be able to explore the effects of background knowledge and task strategies on performance and learning of skills relevant to accomplishing the Air Force mission. In pursuit of that objective, this paper compares three variants of a computational process model of basi...

One of the ways to increase maneuverability wheeled vehicles National Guard Ukraine is use a four-axle chassis with two turntables, which will allow machine turn smallest radius, move crab, sideways and around its own vertical axis. The creation such associated large amount various experiments tests finished sample. development computer technology technologies has led software applications for ...

Mathematical modeling is created for the mathematical task of spatial motion controlled parachute-tether system “wind kite” type. The model consists a main para-chute and braking parachute. parachutes are connected by tether. supposed to be solid body. This body has two planes symmetry. parachute with axial tether an absolutely flexible elastic thread. ideal hinges control carried out changing ...

With the widespread informationization in modern warfare, higher requirements are required for monitoring high-value target’s movement state and corresponding attack conditions. Since impact-angle constraint guidance law can improve striking effect of a missile, study hitting conditions angle range has become particularly important. This paper proposes relationship between missile’s line-of-sig...

Industrial subsea infrastructure inspections using autonomous underwater vehicles (AUV) require high accuracy of AUV navigation relative to the objects being examined. In addition traditional tools with inertial systems and acoustic equipment, technologies video information processing are also actively developed today. The visual odometry-based techniques can provide higher for local maneuverin...

With the rapid development of global trade and maritime transportation, a comprehensive emission inventory is necessary to control air pollution from ships as well comply with international environmental standards. The purpose this study calculate volume emissions in Yeosu Gwangyang ports Korea based on bottom-up approach supported by data automatic identification system (AIS) Korean port manag...

Power output is a unifying theme for bird flight and considerable progress has been accomplished recently in measuring muscular, metabolic and aerodynamic power in birds. The primary flight muscles of birds, the pectoralis and supracoracoideus, are designed for work and power output, with large stress (force per unit cross-sectional area) and strain (relative length change) per contraction. U-s...

in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...
