A classification of on-road obstacles according to their relative velocities [PDF]
The systems based on image processing have numerous applications in the domain of motion control of robots and autonomous vehicles. The current paper is oriented to the solution of the problem that precedes the implementation of automatic avoidance of the on-road obstacles—how to detect them, to track in the sequence of images, and to recognize which ...

Application of Improved Blocked-Off Method to Simulate the Interacting Influences of Obstacle Shape and Wall Velocity on the Turbulent Mixed Convection Flow in a Trapezoidal Cavity [PDF]
In the current research, interaction influences of obstacle shape and top wall velocity on the hydrothermal behaviours of the turbulent mixed convection flow in a trapezoidal cavity are numerically simulated.

Trajectory generation for road vehicle obstacle avoidance using convex optimization [PDF]
This paper presents a method for trajectory generation using convex optimization to find a feasible, obstacle-free path for a road vehicle. Consideration of vehicle rotation is shown to be necessary if the trajectory is to avoid obstacles specified in a ...

Motion planner of mobile robots for obstacles in occluded areas
Motion planning for mobile robots considering occluded obstacles is a navigation challenge in dynamic environments. If an obstacle suddenly appears from the occluded area, a robot might collide with the obstacle. This is the occlusion problem. Therefore,

Obstacle Boundary Point and Expected Velocity‐Based Flocking of Multiagents with Obstacle Avoidance
Obstacle avoidance is a key technology of multiagents flocking control. However, most existing research studies assume that the agent can obtain global information about obstacles and have specific constraints on the shape and boundary of obstacles, which easily limit their practical applications.

Minimum critical velocity of a Gaussian obstacle in a Bose-Einstein condensate [PDF]
When a superfluid flows past an obstacle, quantized vortices can be created in the wake above a certain critical velocity. In the experiment by Kwon et al. [Phys. Rev.
