The industries of shipping, shipbuilding and port operations are among those in which mechanical drives with piston machines widely used. wide use is the result many years experience development modernization machines. Usually, they operate as constant operating speeds, exception combustion engines, a wider range speeds. limiting condition innovation machines, resulting from nature machine oper...

In this paper, an enhanced version of the salp swarm algorithm (SSA) for global optimization problems was developed. Two improvements have been proposed: (i) Diversification SSA population referred as $$_{std}$$ , (ii) parameters are tuned using a self-adaptive technique-based genetic (GA) $$_{GA-tuner}$$ . The novelty developing is to enhance its performance through balancing search exploratio...

This paper presents the development of improved hierarchical control system using metaheuristic centralized PID tuner for DC microgrids. Hierarchical is one best strategies employed in photovoltaics (PV) based microgrids with three layers primary, secondary, and tertiary controllers which at center each these layered levels. The principal objective primary controller to ensure near-equal power ...

The Bestrophin family has been characterized as Cl(-) channels in mammals and Na(+) channels in bacteria, but their exact physiological roles remian unknown. In this study, a natural C-terminally truncated variant of mouse Bestrophin 3 (Best3V2) expression in myoblasts and muscles is demonstrated. Unlike full-length Best3, Best3V2 targets the two important intracellular Ca stores: the lysosome ...

We present a design of broadband and wide dynamic range low noise amplifier/radio frequency variable gain amplifier (LNA/RF VGA) for digital video broadcasting – satellite (DVBS2) receiver tuner integrated circuit fabricated using the 0.18 μm complementary metal oxide semiconductor (CMOS) process. The MOS switching filter was used to get broadband characteristics of the LNA circuit and the MOS ...

An earthquake is a tremor felt on the surface of earth created by movement major pieces its outer shell. Till now, many attempts have been made to forecast earthquakes, which saw some success, but these attempted models are specific region. In this paper, an occurrence and location prediction model proposed. After reviewing literature, long short-term memory (LSTM) found be good option for buil...

The objective of this article is to explore the use dielectrics reconfigure remotely microwave filters in rectangular waveguide. To start, we study experimentally phase shift that achievable using dielectric tuning elements a We then compare results obtained with performance standard metallic cylinders and screws. Next, passive intermodulation (PIM) behavior investigated experimentally. PIM are...
