Large Birds of Prey, Policies That Alter Food Availability and Air Traffic: a Risky Mix for Human Safety

open access: yesHuman-Wildlife Interactions, 2017
Raptors are considered to pose one of the greatest aviation bird strike risk. We investigated raptor bird strikes reported at the largest Spanish airport (Adolfo Suárez Madrid Barajas; AS-MB) from 2009 to 2016 to determine the factors contributing to the

Detailed Post-Soft Impact Progressive Damage Assessment for Hybrid Structure Jet Engines [PDF]

open access: yes
Currently, certification of engine designs for resistance to bird strike is reliant on physical tests. Predictive modeling of engine structural damage has mostly been limited to evaluation of individual forward section components, such as fan blades ...

Compact Modeling of Volatile‐Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

open access: yesAdvanced Intelligent Systems, EarlyView.
A volatile‐switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I−V sweeps, SET kinetics, relaxation dynamics.

Bird Strike Risk for Space Launch Vehicles [PDF]

open access: yes
Within seconds after liftoff of the Space Shuttle during mission STS-114, a turkey vulture impacted the vehicle's external tank. The contact caused no apparent damage to the shuttle, but the incident led NASA to consider the potential consequences of ...

Choosing Your Ground on the Endangered Species Act: How Do the Ninth, Tenth, and District of Columbia Circuit Courts of Appeal Evaluate Water Management Decisions Made by Federal Water Agencies? [PDF]

open access: yes, 2017
The purpose of this article is twofold. First, federal agencies are responsible for the development and implementation of ESA documents, and knowing what a court will look for and at when that document is challenged can help the agencies to develop a ...

MusicSwarm: Biologically Inspired Intelligence for Music Composition

open access: yesAdvanced Intelligent Systems, EarlyView.
Biologically inspired swarms of frozen foundation models self‐organize to compose complex music without fine‐tuning. By coordinating through stigmergic signals, decentralized agents dynamically evolve specialized roles and adapt to solve complex tasks.

Jet Engine Bird Ingestion Simulations: Comparison of Rotating to Non-Rotating Fan Blades [PDF]

open access: yes
Bird strike events in commercial airliners are a fairly common occurrence. According to data collected by the US Department of Agriculture, over 80,000 bird strikes were reported in the period 1990 to 2007 in the US alone (Ref. 1).

Driver Behavior Modeling with Subjective Risk‐Driven Inverse Reinforcement Learning

open access: yesAdvanced Intelligent Systems, EarlyView.
A subjective risk‐driven inverse reinforcement learning framework is proposed to model driver decision‐making. It infers drivers' risk perception and risk tolerance from driving data. A learnable risk threshold is used to regulate decisions, enabling interpretable and human‐like driving behavior decisions.
