Whale Optimization Algorithm (WOA) and Grey Wolf Optimizer (GWO) are well-perform metaheuristic algorithms used by various researchers in solving feature selection problems. Yet, the slow convergence speed issue could demote performance of classification accuracy. Therefore, to overcome this issue, a modified WOA (mWOA) GWO (mGWO) for wrapper-based were proposed study. The mWOA mGWO given new i...

Nowadays, the operation and control of power systems are a big challenge. An essential part system (PS) is load frequency (LFC). Different secondary controllers implemented for problem. Hence, cascaded two-degree freedom tilt-integral-derivative controller having filter (2DOFTIDF) intended in this paper control. In order to determine efficiency 2DOFTIDF controller, well-known non-reheat thermal...

the control of fluidized-bed operations processes is still one of the major areas of research due to the complexity of the process and the inherent nonlinearity and varying dynamics involved in its operation. there are varieties of problems in chemical engineering that can be formulated as nonlinear programming (nlps). the quality of the developed solution significantly affects the performance ...

During a 2 day period in mid-September 2006, more than 200, unconfirmed but identifiable, sei whale (Balaenoptera borealis) calls were collected as incidental data during a multidisciplinary oceanography and acoustics experiment on the shelf off New Jersey. Using a combined vertical and horizontal acoustic receiving array, sei whale movements were tracked over long distances (up to tens of kilo...

The optimal reactive power dispatch (ORPD) is a complex, non-meritorious control issue with continuous and discontinuous variables. This article exhibits whale optimization algorithm (WOA) motivated by the whale’s bubble-net hunting tactic to resolve ORPD. intention comply certain constraints promote voltage transmission quality adequately altering parameters. WOA not only equalizes exploitatio...

Passive acoustic monitoring allows the assessment of marine mammal occurrence and distribution at greater temporal and spatial scales than is now possible with traditional visual surveys. However, the large volume of acoustic data and the lengthy and laborious task of manually analyzing these data have hindered broad application of this technique. To overcome these limitations, a generalized au...

Following an official recommendation in the Faroe Islands that women should abstain from eating mercury-contaminated pilot whale meat, a survey was carried out to obtain information on dietary habits and hair samples for mercury analysis. A letter was sent to all 1180 women aged 26-30 years who resided within the Faroes, and the women were contacted again 1 year later. A total of 415 women resp...
