MGA trajectory planning with an ACO-inspired algorithm [PDF]
, 2009 Given a set of celestial bodies, the problem of finding an optimal sequence of gravity assist manoeuvres, deep space manoeuvres (DSM) and transfer arcs connecting two or more bodies in the set is combinatorial in nature.

Trajectory-Based 3D Point Cloud ROI Determination Methods for Autonomous Mobile Robot
IEEE Access, 2023 With depth cameras and LiDAR improving and generating more data, their applications in 3D point clouds are growing rapidly. However, the vast amount of generated data increases the computational load and results in a shortage of storage space. Therefore,

Discrete Mechanics and Optimal Control for Space Trajectory Design [PDF]
, 2011 Space trajectory design is often achieved through a combination of dynamical systems theory and optimal control. The union of trajectory design techniques utilizing invariant manifolds of the planar circular restricted three-body problem and the optimal ...

Trajectory: A model of the sign and of semiosis
Sign Systems Studies, 2020 This paper examines how far the model of the trajectory as a path that a moving object follows from a source to a goal is an adequate model of the sign and of semiotic processes.

Brachial-ankle pulse wave velocity trajectories in a middle-aged population
Frontiers in Cardiovascular Medicine, 2023 ObjectiveThe “trajectory” phenotype was observed in several cardiovascular risk factors with aging. We aim to identify multiple brachial-ankle Pulse Wave Velocity (baPWV) trajectory phenotypes and assess their determinants.MethodsAmong 5,182 participants
