Some Problems of Berthing of Ships with Non-conventional Propulsions [PDF]

TransNav, 2007
The berthing manoeuvre of ship is the last stage of navigation process. The safety of berthing depends on velocity due impact the quay. In case of ships with non-conventional propulsion (mainly two stern screws and few thrust propellers) the berthing ...

Experimental Evaluation of Unberthing Manoeuvre Control Using an Online Estimation Model Under Actual Sea Conditions [PDF]

TransNav
Ship manoeuvrability varies with speed and is affected by environmental disturbances, making unberthing control challenging. To address this, a control method using an online estimation model is proposed, in which the parameters of a linear motion model ...

An Adaptation of an Algorithm of Search and Rescue Operations to Ship Manoeuvrability [PDF]

TransNav, 2015
This article presents an overview of an algorithm to facilitate action when planning search and rescue operations, taking into account actual hydro-meteorological conditions and the maneuverability of ships involved in the search.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Remaking State Power Through a Paraquat Ban in Malaysia

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper examines the role of the state in its ability to enact environmental regulations. Specifically, this study investigates how Malaysian state actors changed, shifted and betrayed various, oftentimes competing interests to ban paraquat, an acutely toxic herbicide.

Influence of sample intervals in real-sea trails on the nonparametric model of 3-DoF ship motion predictions

Journal of Ocean Engineering and Science
The accuracy of ship manoeuvrability models based on real sea trail data heavily relies on data quality, as noise and measurement errors pose significant challenges in data processing and model training.

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs

Journal of Management Studies, EarlyView.
Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...

Shaping the System Through Turbulence: Strategic Leadership and the Micro‐Foundations of Ecosystem Orchestration in Times of Disruption

Journal of Management Studies, EarlyView.
Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...
