Advancing Model‐Based Systems Engineering in the Development of Naval Vessel Systems Architecture
Systems Engineering, EarlyView.ABSTRACT The increasing complexity of modern naval vessels due to technological advancements poses challenges for early‐stage ship design (ESSD). Developing well‐defined system architectures and adopting systems engineering approaches are essential to address these challenges.

A Systems Engineering Methodology for System of Autonomous Systems: Architecture and Integration
Systems Engineering, EarlyView.ABSTRACT Artificial intelligence and machine learning (AI/ML) rapidly transform systems by providing autonomous capabilities. This new class of systems can become a constituent system in a system of systems (SoS) to evolve it into a system of autonomous systems (SoAS).

Wildlife Biology, EarlyView.Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Comparison Between Helicopter and Cable Crane in Logging Operation
Chemical Engineering Transactions, 2017 In Italy, differently from others European Countries (Switzerland) where the use of helicopters is more diffuse, log transportation in slop land is generally performed by cable crane although its use is generally difficult and high time consuming for ...

Living under the scope: behavior affects survival in a heavily harvested and long‐lived ungulate
Wildlife Biology, EarlyView.The spatiotemporal behavior of game species may play a critical role in their survival throughout the hunting season. Where humans are the most dominant predators, avoidance of landscape features that allow hunter access to hunting grounds can be key to increasing survival.

Monitoring wildlife using long‐endurance solar‐electric UAVs
Wildlife Biology, EarlyView.This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Numerical optimization of helicopter rotor blade design for active twist control
Aviation, 2007 The vibration of a helicopter has several different sources, such as the rotor, engine and transmission system. This creates a number of problems with performance, for example poor manoeuvrability, discomfort of the pilot, low fatigue life of the ...

Micro‐habitat selection by boreal woodland caribou improves access to food
Wildlife Biology, EarlyView.Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

The installation of a common rail diesel engine on a light helicopter of the eurocopter EC120 class
Ingeniería e Investigación, 2016 A feasibility study for the installation of a CRDID (Common Rail Direct Injection Diesel) on a light helicopter is introduced. The total mass available for the CRDID is evaluated starting from fuel consumption and helicopter data.
