In Wireless Sensor Networks (WSNs), routing algorithms can provide energy efficiency. However, due to unbalanced consumption for all nodes, the network lifetime is still prone degradation. Hence, efficient was developed in this article by selecting cluster heads (CH) with help of adaptive whale optimization (AWOA) which used reduce time-consumption delays. The multi-objective function CH select...

Cetacean sighting data collected under various programmes in Colombian Pacific waters were collated with the goal of assessing the distribution and abundance patterns of all species occurring in the exclusive economic zone (EEZ). Distribution maps are presented for 19 species and one genus based on 603 sightings collected between 1986 and 2008. Ordered by sighting frequency, these species were:...

During recent decades, evolutionary algorithms have been widely studied in optimization problems. The multi-objective whale algorithm based on multi-leader guiding is proposed this paper, which attempts to offer a proper framework apply and other swarm intelligence solving adopts several improvements enhance performance. First, search agents are classified into leadership set ordinary by grid m...

In many fields, complicated issues can now be solved with the help of Artificial Intelligence (AI) and Machine Learning (ML). One more modern Metaheuristic (MH) algorithms used to tackle numerous in various fields is Beluga Whale Optimization (BWO) method. However, BWO has a lack diversity, which could lead being trapped local optimaand premature convergence. This study presents two stages for ...

<span lang="EN-US">Renewable energy generation is increasingly attractive since it <br /> non-polluting and viable. Recently, the technical economic performance of power system networks has been enhanced by integrating renewable sources (RES). This work focuses on size solar wind production replacing thermal to decrease cost losses a big electrical system. The Weibull Lognormal prob...

Recent International Whaling Commission (IWC) debate on the interaction of whale watching and whaling provides fertile ground for empirical research (International Whaling Commission 2005). Commentary to date on the relationship between whale watching and whaling has been largely anecdotal, rendering the potential effect whaling might have on whale watching largely uninformed. From this situati...

The use of auditory evoked potential (AEP) measurements has added considerably to knowledge of the hearing mechanisms of marine mammals. We have recently measured the hearing of a stranded infant Risso's dolphin, the audiograms of white-beaked dolphins temporarily caught and released, and the hearing of anaesthetized polar bears. Most small toothed whales echolocate and hear very high frequency...

HIGHLIGHTS Novel whale optimization algorithm is proposed for prediction of breast cancer. Deep learning-based WOA adjusts the CNN structure as per maximum detection accuracy. Proposed method achieves 92.4% accuracy in comparison to 90.3%. Validity evaluated with magnifying factors like 40x, 100 x, 200x, 400x.
