Improved beluga whale optimization algorithm based cluster routing in wireless sensor networks

Mathematical Biosciences and Engineering
<abstract><p>Cluster routing is a critical routing approach in wireless sensor networks (WSNs). However, the uneven distribution of selected cluster head nodes and impractical data transmission paths can result in uneven depletion of network energy. For this purpose, we introduce a new routing strategy for clustered wireless sensor networks

FInCH: Fast statistical inference for continuous‐time animal movement

Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1437-1459, July 2025.
Abstract It is common for movement ecologists to model individual‐level animal movement in discrete time using methods such as hidden Markov models (HMMs). Although often the fitting of HMMs is computationally efficient, the key assumptions required to model in discrete time become limiting when dealing with temporally irregular data or an animal that ...

Optimal Control Strategy for Stability Performance Improvement of Hybrid Power Systems With Electric Vehicle Integration

Energy Science &Engineering, Volume 13, Issue 6, Page 2772-2787, June 2025.
ABSTRACT The present article explores the frequency control of hybrid power systems integrated with electric vehicles (EVs). The hybrid power system is a complicated nonlinear entity that highlights the significant issue of dynamic control owing to inadequate damping under fluctuating load conditions.

An effective approach for uncertainty analysis of power spectral density of stochastic vibration problems via B-spline theory and maximum entropy method [PDF]

The recovery of the probability density function (PDF) of the response of a stochastic dynamic system is a quite thorny problem, since the PDF of structural response, especially the power spectral density (PSD), usually has a complex shape.

Optimum Allocation of Service Transformers in the Presence of Renewable Energy‐Based Distributed Generations Considering Different Load Profiles

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
• As the main contribution, simultaneous optimisation of the site and size of service transformers, WTs and PVs is investigated with respect to the impact of the load profile. In other words, in a distribution network, since it is important to optimally allocate service transformers and various factors can affect the optimal results, this paper focuses
