High-elevation habitats offer ecological advantages including reduced competition, predation, and parasitism [1]. However, flying organisms at high elevation also face physiological challenges due to lower air density and oxygen availability [2]. These constraints are expected to affect the flight maneuvers that are required to compete with rivals, capture prey, and evade threats [3-5]. To test...

The challenge posed by left-turns has been well-documented in literature. Left-turns are thought to be complex roadway sites resulting in a significant proportion of motor-vehicle collisions. The purpose of the present study was to determine whether subjective and objective workload is affected by left-turns of varying complexity (i.e., information processing and maneuvering) in a sample of you...

Marine simulator has been widely used in seafarer training and examination. Besides, in order to reduce the human subjective influence during the examination, the automatic evaluation system for ship maneuvering based on the marine simulator has become more and more necessary. So, the general design idea of the automatic evaluation system of ship maneuvering is proposed. And, considering differ...

Aimed at solving the problem of decreased filtering precision while maneuvering target tracking caused by non-Gaussian distribution and sensor faults, we developed an efficient interacting multiple model–unscented Kalman filter (IMM-UKF) algorithm. By dividing the IMM-UKF into two links, the algorithm introduces the cubature principle to approximate the probability density of the random variabl...

The manipulator with a large degree of redundancy is useful for realizing multiple tasks such as maneuvering the robotic arms in the constrained workspace, e.g. the task of maneuvering the end-effector of the manipulator along a pre-specified path into a window. This paper presents an online technique based on a posture generation rule to compute a null-space joint velocity vector in a singular...

For non-ellipsoidal extended targets and group targets tracking (NETT and NGTT), using an ellipsoid to approximate the target extension may not be accurate enough because of the lack of shape and orientation information. In consideration of this, we model a non-ellipsoidal extended target or target group as a combination of multiple ellipsoidal sub-objects, each represented by a random matrix. ...
