This paper presents a robust hybrid improved dolphin echolocation and ant colony optimization algorithm (IDEACO) for optimization of truss structures with discrete sizing variables. The dolphin echolocation (DE) is inspired by the navigation and hunting behavior of dolphins. An improved version of dolphin echolocation (IDE), as the main engine, is proposed and uses the positive attributes of an...

cephalometric norms of mcnamara analysis have been studied in various populations due to their optimal efficiency. dolphin cephalometric software greatly enhances the conduction of this analysis for orthodontic measurements. however, dolphin is very expensive and cannot be afforded by many clinicians in developing countries. a suitable alternative software program in farsi/english will greatly ...

The resident bottlenose dolphin community at Dolphin Bay in Bocas del Toro sustains the largest dolphin watching (DW) industry in Panama. Our previous work shows that dolphins significantly respond to DW boat presence by modifying their whistle frequency and duration particularly when engaged in foraging activities. The usual assumption is that the noise associated with the DW boats is responsi...

The current conservation status of the bottlenose dolphin (Tursiops truncatus) under the IUCN is 'least concern'. However, in the Caribbean, small and localized populations of the 'inshore form' may be at higher risk of extinction than the 'worldwide distributed form' due to a combination of factors including small population size, high site fidelity, genetic isolation, and range overlap with h...
