Eye white percentage as a predictor of temperament in beef cattle.

open access: yes, 2009
Accurately evaluating and selecting for calm temperament in beef cattle is important for economic and animal welfare reasons. Previous studies have shown that eye white (EW) can be a predictor of a multitude of emotions across different situations, but ...

Realistic modeling of bird flight animations [PDF]

open access: yesACM Transactions on Graphics, 2003
In this paper we describe a physics-based method for synthesis of bird flight animations. Our method computes a realistic set of wingbeats that enables a bird to follow the specified trajectory. We model the bird as an articulated skeleton with elastically deformable feathers.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Influence of wing kinematics on aerodynamic performance in hovering insect flight

open access: yes, 2007
The influence of different wing kinematic models on the aerodynamic performance of a hovering insect is investigated by means of two-dimensional time-dependent Navier–Stokes simulations.

Iceberg Indicators for Animal Welfare in Rural Sheep Farms Using the Five Domains Model Approach

open access: yes, 2020
Animal welfare for sheep in extensive rural farms is difficult to quantify among rural farmers due to several factors, including the lack of technology and the low level of interaction they have with the animals.

Performance of a quasi-steady model for hovering hummingbirds

open access: yesTheoretical and Applied Mechanics Letters, 2015
A quasi-steady model describing aerodynamics of hovering Ruby-throated hummingbirds is presented to study extent of the low-order model in representing the flow physics of the bird and also to separately quantify the forces from the translational ...

SUSPENDED ANIMATION FOR DEEP SPACE FLIGHT

open access: yesASEAN Journal of Psychiatry
The discovery of extrasolar planets as well as the growing number of earth-like exoplanets being detected almost routinely, is galvanizing the interest of the public and space agencies alike to plan for exploratory missions to potentially habitable exoplanets. For manned interstellar space flight, ultralow subzero suspended animation strategies will be

An Experimental High‐Throughput Approach for the Screening of Hard Magnet Materials

open access: yesAdvanced Engineering Materials, EarlyView.
An entire workflow for the high‐throughput characterization and analysis of compositionally graded magnetic films is presented. Characterization protocols, data management tools and data analysis approaches are illustrated with test case Sm(Fe, V)12 based films.

Flight

open access: yes, 2018
Animal flight represents a great challenge and model for biomimetic design efforts. Powered flight at low speeds requires not only appropriate lifting surfaces (wings) and actuator (engine), but also an advanced sensory control system to allow ...

On the move: Influence of animal movements on count error during drone surveys

open access: yesEcology and Evolution
The use of remote sensing to monitor animal populations has greatly expanded during the last decade. Drones (i.e., Unoccupied Aircraft Systems or UAS) provide a cost‐ and time‐efficient remote sensing option to survey animals in various landscapes and ...
