The paper proposes a novel planning approach for optimal sizing of standalone photovoltaic-wind-diesel-battery power supply for mobile telephony base stations. The approach is based on integration of a comprehensive probabilistic sequential Monte Carlo simulator and a black-box optimizer using DIRECT (DIviding RECTangles) method. The main property of the simulator is that input variables are modeled as correlated random processes rather than independent random variables without a time index. By taking ...

The pandemic served to accelerate the contactless method of payment, because payment without contact is now not only a convenience, but a necessity. Before the pandemic in Europe, cash accounted for close to half of the payments, and in just a few weeks of the COVID ...

Monitoring and supervision of overhead power lines have become essential actions in Electrical Power Systems since the introduction of the Smart Grid concept. In order to monitor overhead power lines, simple non-invasive devices are mounted on support poles, which detect line abnormalities and faults by measuring magnetic field originating from power line conductors. Measured signals are also used to determine various electrical and non-electrical line parameters. In this paper a new approximate ...

Abstract The patterns and amount of variation in size, shape, and/or life history traits between females and males are fundamentally important to gain the comprehensive understanding of the evolution of phenotypic diversity. In addition, the covariation of phenotypic traits can significantly contribute to morphological diversification and sexual dimorphism (SD). Using linear and geometric morphometrics, 237 Eristalis tenax specimens sampled from five populations were, therefore, comparatively assessed ...

An improved quantum-behaved particle swarm optimization (IQPSO) algorithm is employed to determine aerosol size distribution (ASD). The direct problem is solved using the anomalous diffraction approximation and Lambert–Beer's Law. Compared with the standard particle swarm optimization algorithm, the stochastic particle size optimization algorithm and the original QPSO, our IQPSO has faster convergence speed and higher accuracy within a smaller number of generations. Optimization parameters for the ...

Project funds can be adequately used to finance the defense system. ...
