Assessment of Crash Risks at Highway Access Points with Restricted Sight Visibility
2020The paper describes an approach of crash risk assessment at midblock access points of highways where sight visibility is restricted due to inadequate corner clearance and also prevailing traffic is mixed in character. Field study was conducted at two junctions on two-lane highways and site details as well as associated traffic data were captured ...

Line-of-sight-pointing stability for dual satellites in non-equatorial orbits
AIAA Guidance, Navigation, and Control Conference and Exhibit, 2000Presented here is the feasibility of a novel attitude control approach for satellites in high altitude inclined elliptic orbits, in order to compensate for the effect of longitudinal as well as lateral drifts relative to the ground terminal. The approach using tether connecting two satellites is proposed for achieving the fixed apparent orientation of ...

Driver’s Sight Point and Dynamics of the Driver-Vehicle-System Related to It
SAE Technical Paper Series, 1968<div class="htmlview paragraph">Since the motor vehicle is controlled by the driver, dynamic consideration of the driver-vehicle system is necessary. In this sytem, eye sight is the most important sense with which the driver gets information from the course. In the present research, first, sighting distance in steady straight running was measured

Improving line-of-sight pointing accuracy of laser communication system based on Kalman filter
Optical Engineering, 2019The size of the field of uncertainty (FOU) is an important performance indicator of spatial optical communication systems and is closely related to the line-of-sight (LOS) pointing accuracy. Considering the aircraft-ground laser communication as the research background, the initial pointing angle of the LOS of communication is obtained using the ...

The design concept of a control for rapid torque-limited slewing of a rigid-mast version of the NASA SCOLE configuration is presented and demonstrated by means of numerical simulation. The time-optimal control problem for the system is decomposed into separate single-axis problems, expanding analytically the implicit nonlinear transcendental expression
