Motion Control and Collision Avoidance Algorithms for Unmanned Surface Vehicle Swarm in Practical Maritime Environment

open access: yesPolish Maritime Research, 2019
The issue of controlling a swarm of autonomous unmanned surface vehicles (USVs) in a practical maritime environment is studied in this paper. A hierarchical control framework associated with control algorithms for the USV swarm is proposed.

The topological strong spatial mixing property and new conditions for pressure approximation [PDF]

open access: yes, 2014
In the context of stationary $\mathbb{Z}^d$ nearest-neighbour Gibbs measures $\mu$ satisfying strong spatial mixing, we present a new combinatorial condition (the topological strong spatial mixing property (TSSM)) on the support of $\mu$ sufficient for ...

Verifying collision avoidance behaviours for unmanned surface vehicles using probabilistic model checking [PDF]

open access: yes, 2016
Collision avoidance is an essential safety requirement for unmanned surface vehicles (USVs). Normally, its practical verification is non-trivial, due to the stochastic behaviours of both the USVs and the intruders.

Characterization of postnatal brain injury and behavioural deficits in a rat model of placental insufficiency‐induced fetal growth restriction

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Fetal growth restriction (FGR) is a common pregnancy complication associated with long‐term neurodevelopmental impairments. Using the reduced uterine perfusion pressure (RUPP) rat model of placental insufficiency‐induced FGR, this study demonstrates that FGR leads to persistent anatomical, histological and behavioural ...

Okapi: Causally Consistent Geo-Replication Made Faster, Cheaper and More Available [PDF]

open access: yes, 2017
Okapi is a new causally consistent geo-replicated key- value store. Okapi leverages two key design choices to achieve high performance. First, it relies on hybrid logical/physical clocks to achieve low latency even in the presence of clock skew.

Influence of acute caffeine on 50-kHz ultrasonic vocalizations in male adult rats and relevance to caffeine-mediated psychopharmacological effects [PDF]

open access: yes, 2010
To further characterize caffeine-mediated psychopharmacological effects, the present study investigated whether acute caffeine (3, 10, 30, 50 mg/kg i.p.) exerted any influence on the emission and features of ultrasonic vocalizations (USVs), which are ...

Dynamic RBC‐To‐Membrane Ratio in 129Xe MRI: A Biomarker of Decreased Lung Function in Pulmonary and Vascular Diseases

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2500-2507, May 2026.
ABSTRACT Purpose To present a method for quantifying dissolved 129Xe spectroscopy using singular value decomposition (SVD) and a dynamic red blood cell (RBC)/membrane ratio as a biomarker of disease. Methods A spectroscopic sequence was performed in 45 subjects (27 healthy, 12 dyspnea of unknown origin [DUO], and 6 pulmonary hypertension [PH ...

Information About Dynamics of the Sea Surface as a Means to Improve Safety of the Unmanned Vessel at Sea

open access: yesPolish Maritime Research, 2016
One of the fundamental states of the sea surface is its heave. Despite of years of the intense scientific inquiry, no clear understanding of the influence of this aspect on the dynamics of the sea environment has emerged.
