Modified Artificial Potential Field for the Path Planning of Aircraft Swarms in Three-Dimensional Environments

Sensors, 2022
Path planning techniques are of major importance for the motion of autonomous systems. In addition, the chosen path, safety, and computational burden are essential for ensuring the successful application of such strategies in the presence of obstacles ...

An Application of Super-Resolution Generative Adversary Networks for Quasi-Static Ultrasound Strain Elastography: A Feasibility Study

IEEE Access, 2020
In this work, a super-resolution approach based on generative adversary network (GAN) was used to interpolate (up-sample) ultrasound radio-frequency (RF) echo data along the lateral (perpendicular to the acoustic beam direction) direction before motion ...

Modified side overlap esophagogastrostomy after laparoscopic proximal gastrectomy

Annals of Gastroenterological Surgery, 2022
We report a new method of esophagogastrostomy after proximal gastrectomy, side overlap with fundoplication by Yamashita (SOFY) in 2017. Recently, even better treatment results can be obtained by modifying the SOFY method.

Trajectory estimation and position correction for hopping robot navigation using monocular camera

ROBOMECH Journal, 2020
In this paper, a navigation and environment mapping method is presented for small exploration robots that use hopping motion. While previous research about hopping rovers mostly focuses on mobility and mechanical design, the motivation for the proposed ...

Collision and obstacle avoidance for agents based on velocity programming in unknown environments under kinematical constraints

IET Control Theory & Applications, 2023
This paper conducts research on obstacle and collision avoidance under kinematical constraints in unknown environments, while communication and simultaneous localization and mapping (SLAM) are unavailable to agents. Then a strategy based on mixed‐integer
