Modeling and Simulation of Automatic Berthing based on Bow and Stern Thruster Assist for Unmanned Surface Vehicle

open access: yes, 2021
In order to solve the technical problems of autonomous berthing of the Unmanned Surface Vehicle (USV), this research has met the requirements of maneuverability berthing under different conditions by effectively using the bow and stern thrusters, which ...

Research on Autonomous Collaborative Berthing of Multi-Tug and Ultra-Large Under-Actuated Vessels

open access: yesJournal of Marine Science and Engineering
In the autonomous berthing of ultra-large under-actuated vessels, the combined effects of low-speed maneuvering and shallow water conditions introduce strong nonlinear hydrodynamic characteristics which cannot be accurately captured by conventional ...

Courting Science: Litigation, Expertise, and Scientific Investment in the Christian Conservative Legal Movement

open access: yesLaw &Policy, Volume 48, Issue 4, October 2026.
ABSTRACT In this article we analyze case studies of abortion and marriage equality to identify how judicial discretion and signaling prodded conservative investments in new movement organizations charged with overcoming scientific expertise barriers that had previously stymied conservative policy victories.

On 3‐MMC: A Cathinone I Have Come to Know and Love

open access: yesAnthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,

(Im)possibility of Redress: Mega‐Infrastructures and the Voided Politics of Contestation

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 3, September 2026.
ABSTRACT Drawing on critical geography's recent engagement with negativity, this article intervenes in dominant relational approaches to infrastructure by examining the (im)possibility of redress under mega‐infrastructure development through a case study of the Lamu Port–South Sudan–Ethiopia Transport (LAPSSET) Corridor in coastal Kenya.

A Testbed to Evaluate the Tasks to be Executed by Autonomous Space Robots: An Experiment on Satellite Berthing.

open access: yesJournal of the Robotics Society of Japan, 1998
We developed the Advanced Space Robot Testbed with Redundant Arms (ASTRA) for studying the autonomous control of a space robot. Berthing a satellite that is moving in space is the kind of difficult and dangerous task expected of space robots. This paper describes a robot which berthes a mockup satellite that is moving and rotating in zero gravity.

Shore Construction Detection by Automotive Radar for the Needs of Autonomous Surface Vehicle Navigation

open access: yesISPRS International Journal of Geo-Information, 2019
Autonomous surface vehicles (ASVs) are becoming more and more popular for performing hydrographic and navigational tasks. One of the key aspects of autonomous navigation is the need to avoid collisions with other objects, including shore structures ...

Temporal Shifts in Subtidal Rocky Benthic Communities Associated With the Invasion of Rugulopteryx okamurae in a Port Environment

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The invasive brown alga Rugulopteryx okamurae, native to the northwestern Pacific, has rapidly expanded along the European Atlantic coast, reaching the Basque Coast in 2023, and was likely already present in 2022. Using annual data from a monitoring survey conducted between 2010 and 2025, this study assesses the spatio‐temporal variability of ...

Phased manifold-based RRT*: An optimized motion planning approach for autonomous bow-in berthing of inland vessels

open access: yesJournal of Ocean Engineering and Science
To address the issue of autonomous bow-in berthing for inland vessels under environmental influence, a phased manifold-based rapidly-exploring random tree star (PMRRT*) approach is proposed for the trajectory and posture planning (TPP).
