Inbreeding depression is widely hypothesized to drive adaptive evolution of precopulatory and post-copulatory mechanisms of inbreeding avoidance, which in turn are hypothesized to affect evolution of polyandry (i.e. female multiple mating). However, surprisingly little theory or modelling critically examines selection for precopulatory or post-copulatory inbreeding avoidance, or both strategies...

This paper focuses on the orbit avoidance strategy of the optical remote sensing satellite. The optical remote sensing satellite, moving along the Sun-synchronous orbit, is equipped with laser warning equipment to alert CCD camera from laser attacks. This paper explores the strategy of satellite avoidance to protect the CCD camera and also the satellite. The satellite could evasive to several t...

A mobile robot system, capable of performing various tasks for the physically disabled, has been developed. To avoid collision with unexpected obstacles, the mobile robot uses ultrasonic range finders for detection and mapping. The obstacle avoidance strategy used for this robot is described. Since this strategy depends heavily on the performance of the ultrasonic range finders, these sensors a...

Given δ and n, a minimum degree game starts with n disconnected nodes. Two players alternate, each adding a new edge in turn, until the resulting graph has minimum degree at least δ. In the achievement game, the last player to move is the winner; in the avoidance game, the last to play is the loser. We determine a winning strategy for the avoidance game for every δ and n. The achievement game i...

Aquatic plants anchored in streams are under pressure from various constraints linked to the water flow and display strategies to prevent their damage or destruction. We assume that the responses of aquatic plants to fast-water flow are a manifestation of a trade-off consisting in either maximizing the resistance to damage (tolerance strategy) in minimizing the hydrodynamic forces (avoidance st...

This research paper proposes a real-time obstacle avoidance strategy for mobile robots with monocular camera. The approach uses binary semantic segmentation FCN-VGG-16 to extract features from images captured by the camera and estimate position distance of obstacles in robot’s environment. Segmented are used create frontal view robot. Then, optimized path planning based on enhanced A* algorithm...
