Problems with voltage and stability have arisen as a result of the dramatic development in renewable energy generating units, notably solar systems linked to low medium networks, influence active loads that vary rapidly from time during day. Because reactive power is directly proportional voltage, its use producing units can only improve their efficiency. Better performance for these controller...

The paper applies jellyfish search algorithm (JSA) for reaching the maximum profit of IEEE 30-node and 118-node transmission power networks considering electrical market wind turbines (WTs). JSA is compared with particle swarm optimization (PSO), genetic (GA), moth (MSA), salp (SSA), water cycle (WCA) three study cases. same different electric prices all nodes are, respectively, considered in C...

Wireless Mesh Networks (WMNs) have rapid real developments during the last decade due to their simple implementation at low cost, easy network maintenance, and reliable service coverage. Despite these properties, nodes placement of such networks imposes an important research issue for operators influences strongly WMNs performance. This challenging is known be NP-hard problem, solving it using ...

In this paper, an improved coyote optimization algorithm (ICOA) is developed for determining control parameters of transmission power networks to deal with optimal reactive dispatch (ORPD) problem. The performance ICOA method superior its conventional (COA) thanks modifications two new solution generations COA. COA uses a center generate update step size in the first generation and produced one...

A raga is a unique set of notes with certain rules that carefully followed, retain and protect its purity produce amazing musical effects. An automated transcription identification important for computational musicology, which an step musicology indexing, classifying, recommending tunes. In the present research, audio features such as mel frequency cepstrum coefficients (MFCCs), spectral flux, ...

Abstract Groundwater (GW) plays a key role in water supply basins. As global warming and climate change affect groundwater level (GWL), it is important to predict for planning managing resources. This study investigates the GWL of Yazd-Ardakan Plain basin Iran base period 1979–2005 predicts periods 2020–2059 2060–2099. Lagged temperature rainfall are used as inputs hybrid standalone artificial ...
