Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Atlas: Commercial fisheries for shellfish around Ireland [PDF]

, 2017
Fishing is the longest standing and most prevalent marine activity in the territorial and coastal waters of Ireland. Today over 2,000 vessels are registered as commercial fishing vessels and over 80% of these are under 12m in length and depend largely or

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Linear Modelling of Marine Vessels Fuel Consumption for Ration of Subsidized Fuel

International Journal of Maritime Technology, 2018
An approach to deal with the phenomenon of maritime fuel smuggling is to control the quantity of fuel that is supplied to vessels. For the same reason, fuel is delivered to marine vessels in Iran in accordance with the ration defined by the National ...

Marine vessels alter the behaviour of bottlenose dolphins Tursiops truncatus in the Istanbul Strait, Turkey

Endangered Species Research, 2017
The non-lethal impacts of marine vessels on cetaceans are now a globally recognised threat. This study is the first to investigate the effect of marine traffic on the behaviour of bottlenose dolphins Tursiops truncatus in the Istanbul Strait, Turkey. The

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.
