Experimental study on the effects of stern bulb arrangement on the slamming load

International Journal of Naval Architecture and Ocean Engineering, 2020
The present study concerns the stern slamming load of container carriers, with stern bulb arrangement variation. First, a series of wedge drop tests were conducted using simple wedge models with fixed deadrise angles, and tests with the cross-section ...

A Simulation Model for a Hybrid‐Electric Craft in Restricted Waters

Journal of Advanced Transportation, Volume 2020, Issue 1, 2020., 2020
Sustainable mobility is one of the most challenging issues for passenger transport inside environmental protected areas and ecologically fragile environments. To reduce the pollutant emissions, the adoption of electric or hybrid‐electric solutions for crafts propulsion is a suitable option for green navigation.

Analysis of the Effect of Addition of Bilge Keel, Bulbous Bow, Skeg and Combination on Value of Ship Resistance and Seakeeping of Ship using CFD Method

Proceedings of the 7th International Seminar on Ocean and Coastal Engineering, Environmental and Natural Disaster Management, 2019
: The hull added by the Bulbous Bow, Skeg, and Bilge Keel can improve the ship's ability to operate. Based on several studies it is known that the best bulbous bow model is the V model, the best Skeg form is the Foil model and the most optimal Bilge Keel

THE SIMULATION OF SKEG EFFECT TO BARGE RESISTANCE CALCULATION USING CFD-RANS OPENFOAM

Wave, 2021
The paper discusses the significance of different types of skegs in a barge toward the pressure, fluid velocity and the ship total resistance. There are three kinds of skeg configurations: barge without skegs, skegs without deflection, and skegs with ...

Variability in Overwinter Antarctic Krill Transport Pathways and Connectivity in the South‐West Atlantic Sector of the Southern Ocean

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Our study demonstrates that particles transported within sea ice are advected over substantially larger distances compared with those transported solely by ocean currents, indicating that sea ice dynamics play a dominant role in enhancing long‐range particle dispersal in the Southern Ocean relative to ocean‐only transport.

Eveningness in Middle‐Aged and Older Adults: Associations With Sleep, Internalising Symptoms, and Alertness

Journal of Sleep Research, Volume 35, Issue 1, February 2026.
ABSTRACT Evening chronotype, characterised by a preference for later circadian timing, can present challenges in societal activities oriented towards morning schedules. This study investigates the link between chronotype and sleep, alertness, and internalising symptoms in middle‐aged and older adults. The sample comprised 652 healthy adults (ages 35–98)

Characterizing watercraft‐related mortality of sea turtles in Florida

The Journal of Wildlife Management, Volume 83, Issue 5, Page 1057-1072, July 2019., 2019
ABSTRACT Mortality from being struck by a motorized watercraft is considerable for many aquatic vertebrates around the world, including sea turtles. We studied stranded (i.e., dead, sick, or injured) sea turtles found in Florida, USA, during 1986–2014 and identified those with sharp force or blunt force injuries indicative of a vessel strike.

Approximating the smallest $k$-enclosing geodesic disc in a simple polygon

Journal of Computational Geometry
We consider the problem of finding a geodesic disc of smallest radius containing at least $k$ points from a set of $n$ points in a simple polygon that has $m$ vertices, $r$ of which are reflex vertices. We refer to such a disc as a SKEG disc. We present

The Challenges of Being Left Behind: Peripheralisation in English Small Rural Towns

Sociologia Ruralis, Volume 66, Issue 1, January 2026.
ABSTRACT Rural small towns have long been viewed as places of retail and service provision for both their populations and people in surrounding rural hinterlands, although in many countries these roles are in decline, with these settlements increasingly viewed as ‘left behind places’ experiencing peripheralisation.
