Doppler–Kinematic Spatio-Temporal Graph Learning for Low-Slow-Small Target Recognition Using Multi-Dimensional Radar Observations

Remote Sensing
Low-slow-small (LSS) target recognition using multi-dimensional radar remains challenging due to weak signatures, similar kinematics, and overlapping short-term Doppler patterns. Digital-array radar provides continuous, complementary Doppler-spectrum and

An application of graph theory and nonlinear programming to the kinematic synthesis of mechanisms

Mechanism and Machine Theory, 1991
In this investigation a systematic 'start-from-zero' approach for the design of mechanisms has been described and applied to the creation of automotive windshield wiper mechanism. Following specification of the design goals and restrictions, the potentially useful kinematic structures have been generated with the aid of graph theory.

Kinematic structure correspondences via hypergraph matching [PDF]

, 2016
In this paper, we present a novel framework for finding the kinematic structure correspondence between two objects in videos via hypergraph matching. In contrast to prior appearance and graph alignment based matching methods which have been applied among

Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

Advanced Intelligent Systems, EarlyView.
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...
