RESPONSE TIME OF AN AVIAN PREY TO A SIMULATED HAWK ATTACK IS SLOWER IN DARKER CONDITIONS, BUT IS INDEPENDENT OF HAWK COLOUR MORPH

Response time of an avian prey to a simulated hawk attack is slower in darker conditions, but is independent of hawk colour morph

To avoid click here predation, many species rely on vision to detect predators and initiate an escape response.The ability to detect predators may be lower in darker light conditions or with darker backgrounds.For birds, however, this has never been experimentally tested.We test the hypothesis that the response time of avian prey (feral pigeon Colu

SiaN-VO: Siamese Network for Visual Odometry

click here Despite the significant advancements in drone sensory device reliability, data integrity from these devices remains critical in securing successful flight plans.A notable issue is the vulnerability of GNSS to jamming attacks or signal loss from satellites, potentially leading to incomplete drone flight plans.To address this, we introduce

Semi-universal geo-crack detection by machine learning

Introduction: Cracks are a key feature that determines the structural integrity of rocks, and their angular distribution can be used to determine the local or regional stress patterns.The temporal growth of cracks can be monitored in order to predict impending failures of materials or structures such as a weakened dam.Thus, cracks and their spatial
